The Criminal Courts of France: Criminal Jurisdiction, Trial Courts, and the Organisation of Criminal Justice

Introduction

The criminal justice system of France is organised around a structured hierarchy of courts within the ordre judiciaire (judicial order). Its central purpose is to determine whether a person has committed a criminal offence, establish the applicable legal responsibility, impose a lawful sentence where guilt is proved, and protect the procedural rights of everyone involved. Although criminal proceedings are conducted within the same judicial order as civil litigation, they operate according to distinct rules, institutions, and principles reflecting the special consequences of criminal liability.

French criminal law distinguishes three principal categories of offences: contraventions, délits, and crimes. This classification is fundamental because it determines which court has jurisdiction, the procedural framework that applies, the possible penalties, and, in serious cases, whether an investigating judge must conduct a formal judicial investigation. Minor offences are generally dealt with by the tribunal de police; intermediate offences by the tribunal correctionnel; and the most serious crimes by the cour d’assises or, for specified offences, the cour criminelle départementale.

The organisation of criminal justice cannot, however, be understood simply as a list of courts. It is a system in which several institutions perform different functions. The public prosecutor directs or supervises criminal investigations and decides whether to bring proceedings; the police and gendarmerie investigate suspected offences under judicial authority; investigating judges conduct judicial investigations in cases requiring them; trial courts determine guilt and sentence; and appellate courts review decisions within the limits established by procedural law. The Cour de cassation ensures the correct interpretation and application of law without ordinarily conducting a new trial on the facts.

A defining characteristic of the French model is therefore the distinction between investigation, prosecution, adjudication, and review. These functions interact, but they are not interchangeable. The public prosecutor represents the public interest in the enforcement of criminal law, while the trial court must independently assess the evidence and decide whether the legal conditions for conviction have been satisfied.

This article examines the structure and jurisdiction of the French criminal courts, the classification of offences, the principal stages of criminal proceedings, the role of judges and prosecutors, the rights of defendants and victims, and the mechanisms through which criminal judgments may be challenged and enforced. It also considers the influence of European human-rights standards and the practical challenges facing contemporary French criminal justice.

1. The constitutional and institutional foundations of criminal justice

French criminal courts form part of the ordre judiciaire, the judicial order responsible both for resolving private-law disputes and for determining criminal responsibility. This institutional arrangement reflects the dual structure of the French legal system: judicial courts exercise criminal jurisdiction, while administrative courts generally review disputes involving the exercise of public administrative authority.

The distinction is important because criminal proceedings may involve public officials, regulatory authorities, police officers, or public institutions without thereby becoming administrative litigation. Where the question is whether a person has committed an offence under criminal law, the matter ordinarily belongs to the judicial order. The criminal courts apply the Code pénal (Penal Code) and the Code de procédure pénale (Code of Criminal Procedure), subject to constitutional guarantees, international obligations, and the European Convention on Human Rights.

The organisation of criminal justice is governed principally by three bodies of law:

• The Constitution of 1958, which establishes the institutional framework of the Republic and protects fundamental principles relevant to judicial authority and individual liberty.
• The Penal Code, which defines criminal offences, the conditions of criminal responsibility, and the penalties that may be imposed.
• The Code of Criminal Procedure, which regulates investigations, prosecutions, judicial investigations, trials, appeals, and the enforcement of criminal judgments.

The Constitutional Council also plays an important role. Through constitutional review, including the question prioritaire de constitutionnalité (QPC), it may examine whether statutory provisions applicable to criminal proceedings comply with constitutionally protected rights and freedoms. The ordinary criminal courts, however, remain responsible for applying criminal legislation to individual cases.

The institutional system is not limited to the courts that conduct trials. It includes the ministère public (public prosecution service), judicial police, investigating judges, judges responsible for pre-trial liberty, and judges responsible for the enforcement of sentences. These actors perform different functions within a common procedural framework.

A fundamental distinction must therefore be maintained between the authority that investigates and prosecutes an alleged offence and the authority that determines guilt. The public prosecutor may decide to bring a case before a criminal court, but the prosecutor cannot determine the defendant’s guilt. That decision belongs to the competent judicial body, which must assess the evidence independently and apply the law.

2. The classification of criminal offences: contraventions, délits, and crimes

The starting point for understanding French criminal jurisdiction is the classification of offences according to their seriousness. Article 111-1 of the Penal Code divides criminal offences into three categories: contraventions, délits, and crimes. This is not merely a descriptive classification. It determines the competent court, the applicable procedural rules, the potential penalties, and often the institutions responsible for investigating and prosecuting the matter. Légifrance+1

2.1. Contraventions: the least serious offences

Contraventions are the least serious category of criminal offences. They include conduct such as certain traffic violations, public disturbances, and minor breaches of legal obligations. They are divided into five classes, with the fifth class representing the most serious category of contravention.

The principal penalty is a fine. Contraventions do not carry imprisonment as a criminal penalty, although additional measures may be imposed where legislation permits. Depending on the offence, these may include suspension of a driving licence, confiscation of specified objects, or an obligation to complete a particular course or programme.

The amount of the fine depends on the class of the offence and the applicable statutory provisions. The classification is therefore determined by law rather than by the subjective assessment of the police officer, prosecutor, or judge.

The ordinary court for contraventions committed by adults is the tribunal de police. Some minor offences may be dealt with through simplified procedures without a conventional public hearing. More serious contraventions may be examined at a hearing, where the defendant can contest the accusation and the evidence.

2.2. Délits: intermediate criminal offences

Délits occupy the middle category. They include a broad range of conduct, such as theft, fraud, assault, certain forms of harassment, drug-related offences, and various economic or financial crimes.

The ordinary court with jurisdiction over offences in this category is the tribunal correctionnel. Unlike the tribunal de police, it may impose imprisonment, subject to the maximum penalty prescribed for the particular offence. It may also impose fines, community service, probationary measures, professional prohibitions, driving restrictions, confiscation, and other supplementary penalties.

The general statutory framework permits imprisonment of up to ten years for many offences classified as délits, although individual offences may carry different maximum penalties and certain circumstances, including legally defined recidivism, may increase the applicable maximum. The sentence imposed in an individual case must be determined within the limits of the relevant legislation and the general principles governing sentencing.

The category is particularly important because it covers a wide variety of conduct. A relatively straightforward theft case and a complex financial fraud prosecution may both fall within the jurisdiction of the tribunal correctionnel, even though their factual complexity, evidence, and potential consequences differ considerably.

2.3. Crimes: the most serious offences

Crimes constitute the most serious category of criminal offences. They include murder, assassination, rape, certain forms of armed robbery, and other offences for which the Penal Code prescribes criminal imprisonment (réclusion criminelle or, in some cases, détention criminelle).

The applicable penalties may range from fifteen years to life imprisonment, depending on the offence and its legally defined circumstances. The distinction between réclusion criminelle and détention criminelle reflects the statutory terminology used for criminal penalties; it does not create a separate hierarchy of trial courts.

Criminal cases in this category are generally heard by either the cour criminelle départementale or the cour d’assises. The division of jurisdiction depends on the statutory penalty, the age and legal status of the accused, the circumstances of the case, and other rules established by the Code of Criminal Procedure.

The distinction between délit and crime is particularly consequential. It determines not only the trial court but also the procedural route by which a case may reach trial. Serious criminal cases ordinarily involve a formal judicial investigation conducted by an investigating judge before the accused is committed for trial.

2.4. Why the classification matters

The classification of an offence is determined by the law defining the conduct and its applicable penalty, not simply by the apparent seriousness of the facts. A violent incident, for example, may be classified as a délit or a crime depending on the legal elements established by the prosecution and the circumstances specified in the relevant provision.

Where a single case involves several offences, the rules governing connected offences and jurisdiction become important. A court competent to hear the most serious offence may, in appropriate circumstances, also determine related offences. The purpose is to avoid fragmented proceedings and inconsistent findings where the accusations form part of a connected factual situation.

The distinction is also relevant to limitation periods, investigative powers, detention rules, and the availability of particular procedural mechanisms. A legal classification therefore has consequences extending far beyond the name of the court in which a trial takes place.

3. The tribunal de police: jurisdiction over contraventions

The tribunal de police is the criminal court responsible for judging contraventions committed by adults. It sits within the tribunal judiciaire, the general first-instance court of the judicial order, rather than operating as an entirely separate institution.

Its jurisdiction is defined by the category of offence. Under Article 521 of the Code of Criminal Procedure, the tribunal de police hears contraventions. The court ordinarily sits with a single professional judge, assisted by a court registrar. The public prosecution service may be represented by the procureur de la République or a deputy prosecutor. Ministère de la justice+1

The court’s role is to determine whether the alleged contravention has been established and, if so, to impose the penalty authorised by law. It may acquit the defendant where the evidence is insufficient or the legal elements of the offence have not been demonstrated.

The principal sanctions are fines. Depending on the offence, additional penalties may also be imposed. These can include suspension of a driving licence, confiscation of certain property, or other measures specifically authorised by legislation.

The tribunal de police does not impose imprisonment for contraventions. This distinguishes it from the tribunal correctionnel, which has jurisdiction over offences punishable by imprisonment.

3.1. Simplified proceedings and hearings

Not every contravention requires a full oral hearing. French criminal procedure permits certain cases to be dealt with through simplified procedures, particularly where the nature of the offence and the available evidence make a conventional hearing unnecessary.

However, simplified treatment does not eliminate the procedural rights of the person concerned. The defendant must have access to the applicable legal remedies and the opportunity to contest the decision in accordance with the relevant procedural rules.

Where a hearing takes place, the court examines the accusation, the evidence, and any arguments submitted by the defendant. The public prosecution service may request a particular penalty, but the court is not required simply to adopt the prosecutor’s position. It must reach its own decision.

3.2. The practical significance of the court

Although the tribunal de police deals with the least serious category of criminal offences, its work is important to the everyday administration of justice. Traffic violations, public-order offences, and other regulatory breaches can affect individuals’ finances, professional activities, and legal status.

A conviction may also have consequences beyond the immediate fine. Certain offences may result in supplementary restrictions or be relevant to subsequent legal proceedings. The court must therefore apply the statutory framework carefully, even where the potential penalty is comparatively limited.

4. The tribunal correctionnel: the principal court for misdemeanours

The tribunal correctionnel is the ordinary first-instance criminal court for délits committed by adults. It is one of the most frequently used criminal jurisdictions in France and handles a wide range of offences, from theft and fraud to assault, drug offences, and complex financial misconduct.

Its jurisdiction is defined principally by the nature of the offence. It also has authority, in appropriate circumstances, to determine related contraventions and connected offences. For example, where a traffic incident gives rise to both a contravention and a more serious offence of involuntary injury, the correctional court may examine the connected allegations together. Ministère de la justice+1

4.1. Composition of the court

The ordinary formation of the tribunal correctionnel consists of three professional judges: a president and two other judges. This collegial composition is intended to provide collective judicial deliberation and a considered assessment of the evidence and legal issues.

However, French procedure permits a single professional judge to hear specified categories of offences. Article 398-1 of the Code of Criminal Procedure identifies the offences that may be dealt with under this simplified judicial formation. The precise availability of single-judge proceedings depends on the statutory provisions applicable to the particular offence.

The use of a single judge does not mean that the proceedings cease to be judicial or that the defendant loses the ordinary guarantees of criminal procedure. The judge must still assess the evidence, hear the parties in accordance with the applicable rules, and give a reasoned decision.

For particularly lengthy or complex trials, additional judicial arrangements may be made to ensure continuity of the hearing. The Code of Criminal Procedure provides mechanisms for additional judges to attend proceedings where extensive debates are anticipated.

4.2. The jurisdiction and powers of the correctional court

The tribunal correctionnel determines whether the defendant has committed the offence charged and, if so, what penalty is appropriate within the statutory limits.

It may impose:

• imprisonment, where authorised by the offence-specific legislation;
• fines;
• community service;
• probationary and other alternative measures;
• professional or occupational prohibitions;
• driving restrictions;
• confiscation of property;
• other supplementary penalties prescribed by law.

The court also determines the civil consequences of the offence where a victim has joined the criminal proceedings as a partie civile. This permits the criminal court to examine claims for compensation arising from the alleged criminal conduct, subject to the applicable rules.

The distinction between criminal and civil responsibility remains important. A person may be acquitted of a criminal charge while a separate civil claim raises different legal questions, depending on the applicable procedural and substantive rules. Conversely, a criminal conviction may provide the basis for an award of compensation to a victim who has properly constituted themselves as a civil party.

4.3. Public hearings and judicial reasoning

Hearings before the tribunal correctionnel are generally public. Publicity enables citizens and the press to observe the administration of criminal justice and supports confidence in judicial proceedings.

Nevertheless, publicity is not absolute. The court may restrict public access where the law permits, including to protect privacy, public order, or other legally recognised interests. The need to protect victims, particularly in cases involving sexual offences or vulnerable persons, may justify restrictions on public attendance.

At the conclusion of the proceedings, the court delivers a judgment addressing the charges and the legal consequences. It must explain the basis of its decision in accordance with the applicable procedural requirements.

4.4. Different routes to a correctional trial

A case may reach the tribunal correctionnel through several procedural routes. These include:

• Convocation par procès-verbal: a defendant is summoned following a procedure in which the police or gendarmerie officer records the relevant procedural information.
• Convocation par officier de police judiciaire: the defendant is summoned by an officer of the judicial police in accordance with statutory conditions.
• Comparution immédiate: a procedure allowing a defendant to be brought before the court rapidly after the investigation, where the statutory conditions are satisfied.
• Comparution à délai différé: a procedure allowing the case to proceed to trial after a short delay where certain investigative or evidential steps remain necessary.
• Comparution sur reconnaissance préalable de culpabilité (CRPC): a procedure based on the defendant’s admission of guilt and a proposed penalty, subject to statutory conditions and judicial approval.

These mechanisms are not interchangeable. Each has its own conditions, safeguards, and consequences. In particular, the CRPC procedure is not simply a private agreement between the prosecutor and defendant: the proposed outcome must be examined by a judge, and the defendant must receive the assistance and information required by law.

The choice of procedure depends on the circumstances of the case, the available evidence, the nature of the offence, and the statutory requirements. service-public.gouv.fr+1

5. The cour criminelle départementale: a professional criminal court for specified serious offences

The cour criminelle départementale occupies a distinctive position in the French criminal justice system. It was introduced to hear certain serious criminal cases at first instance without a citizen jury, using a panel composed entirely of professional judges.

Its jurisdiction and composition have been subject to legislative development. An important change took effect on 25 July 2026 through Law No. 2026-651 of 23 July 2026 on criminal justice and respect for victims. The amended Article 380-16 of the Code of Criminal Procedure now provides that adults accused of crimes punishable by fifteen or twenty years of criminal imprisonment are tried at first instance by the cour criminelle départementale. The amended provision no longer includes the former exclusion based on legal recidivism. Légifrance+1

This recent legislative change matters because some official explanatory pages still describe the earlier jurisdictional rule, under which the court’s competence was framed around crimes punishable by fifteen to twenty years and the absence of legal recidivism. The current statutory text must take precedence over older summaries.

5.1. Composition

Under Article 380-17 of the Code of Criminal Procedure, the cour criminelle départementale is composed of five professional judges: one president and four assessors. The judges are selected from the relevant judicial magistracy, subject to the statutory rules governing their appointment to the formation.

Unlike the ordinary cour d’assises, the cour criminelle départementale does not include a jury of citizens. The determination of guilt and the sentence are made by professional judges.

The public prosecution service is represented by the avocat général or the appropriate prosecutor, depending on the organisation of the proceedings. The accused is entitled to legal representation and the procedural safeguards applicable to criminal trials.

5.2. Jurisdiction and limits

The court’s competence is not determined simply by the general description of an offence as serious. Article 380-16 establishes a specific statutory threshold based on the penalty prescribed for the crime.

The court also has jurisdiction over connected misdemeanours in the circumstances provided by law. However, it is not competent where one or more co-accused do not satisfy the statutory conditions set out in Article 380-16. Such rules matter in cases involving several defendants, where the legal classification and applicable penalties may differ between participants.

The cour criminelle départementale is not a general replacement for the cour d’assises. Crimes outside its statutory jurisdiction remain within the jurisdiction of the latter court. The cour d’assises therefore continues to hear the most serious criminal cases and other cases assigned to it by law.

5.3. The 2026 reform and the need for current legal interpretation

The 2026 amendment illustrates why the criminal courts must be understood through the legislation in force at the relevant date. Older descriptions of the cour criminelle départementale may refer to the former recidivism exclusion or describe its jurisdiction in broader terms than the current statutory wording permits.

For legal research, the controlling reference is the version of Article 380-16 in force on the date relevant to the proceedings. The legislative reform also amended other provisions concerning the organisation and composition of criminal courts. Accordingly, a description based solely on pre-July 2026 procedural guidance may be incomplete. Légifrance+1

6. The cour d’assises: trial of the most serious crimes

The cour d’assises is the traditional French criminal court for serious crimes. It is a departmental jurisdiction, and its proceedings are characterised by the participation of professional judges and citizens selected to serve as jurors.

It hears cases involving crimes that fall outside the statutory jurisdiction of the cour criminelle départementale, including offences punishable by thirty years of criminal imprisonment or life imprisonment. It also retains jurisdiction in other circumstances assigned to it by the Code of Criminal Procedure.

6.1. Composition of the court

At first instance, the ordinary cour d’assises is composed of three professional judges: a president and two assessors. They sit together with six citizens selected as jurors.

The jury is an important feature of the French criminal justice system. It introduces citizen participation into the determination of criminal responsibility for particularly serious offences. Jurors are not merely observers; they participate in the deliberations and decision-making process under the statutory rules.

The public prosecution service is represented by the avocat général, who presents the prosecution’s case and requests the application of criminal law. The accused is represented by a lawyer, and the victim may participate as a civil party where the relevant conditions are satisfied.

6.2. The role of jurors

The participation of jurors reflects the idea that the judgment of serious crimes is not exclusively a matter for professional judicial institutions. Citizens are called upon to participate in the administration of criminal justice, alongside judges trained in law and procedure.

Jurors must assess the evidence presented at trial, consider the arguments of the prosecution and defence, and participate in deliberations on guilt and sentence. Their role is subject to procedural safeguards designed to ensure that decisions are based on the evidence and the law rather than external pressure or personal prejudice.

The composition of the court differs on appeal. The appellate cour d’assises ordinarily includes three professional judges and nine jurors. This larger jury reflects the special structure of the appellate trial of serious criminal cases. service-public.gouv.fr+1

6.3. The trial and the examination of evidence

Proceedings before the cour d’assises are generally oral and involve an extensive examination of the evidence. Witnesses may be heard, experts may present their findings, and the accused may be questioned about the alleged conduct.

The court examines not only the factual elements of the offence but also the legal conditions of criminal responsibility. The prosecution must establish the elements of the alleged crime, while the defence may challenge the reliability, relevance, or interpretation of the evidence.

The accused has the right to challenge the prosecution’s case, present arguments, and receive legal assistance. The presumption of innocence remains applicable throughout the proceedings. The seriousness of the accusation does not diminish the requirement that guilt be established in accordance with the law.

6.4. Publicity and closed hearings

The principle of public hearings applies to the cour d’assises, but it is subject to statutory exceptions. A court may order proceedings to take place à huis clos, meaning without public attendance, where the law permits.

This may be particularly relevant in cases involving sexual offences, minors, or circumstances in which public disclosure would seriously affect protected interests. The restrictions are intended to reconcile the public character of justice with the protection of privacy, dignity, and vulnerable participants.

7. Specialised criminal courts and national prosecution structures

The ordinary criminal courts do not handle every category of criminal conduct through the same institutional arrangements. French law has developed specialised jurisdictions and prosecution services for offences requiring particular expertise, central coordination, or national and international investigative capacity.

Specialisation is particularly important in cases involving terrorism, organised crime, large-scale financial misconduct, and serious offences crossing regional or national borders.

7.1. The juridictions interrégionales spécialisées (JIRS)

The juridictions interrégionales spécialisées are specialised judicial structures established to deal with particularly complex criminal cases. They operate across several judicial districts and bring together prosecutors and investigating judges with experience in organised crime and serious economic and financial offences.

Their areas of work include complex cases involving:

• organised drug trafficking;
• human trafficking and aggravated exploitation;
• arms trafficking;
• organised extortion;
• money laundering;
• corruption and influence-peddling;
• serious financial fraud;
• complex offences involving multiple defendants or jurisdictions.

The JIRS framework is designed to address cases that exceed the practical capacity or expertise of an ordinary local investigation. It may involve coordination across several regions, specialist investigative techniques, and cooperation with foreign authorities.

The JIRS are not a separate category of criminal trial court equivalent to the tribunal correctionnel or cour d’assises. Rather, they are specialised judicial arrangements through which investigation, prosecution, and judicial proceedings may be handled by designated authorities with wider territorial competence. Ministère de la justice

7.2. The Parquet national antiterroriste (PNAT)

The Parquet national antiterroriste was established in 2019 to centralise and coordinate the prosecution of terrorism-related offences and certain other exceptionally serious international crimes.

Based in Paris, it has national jurisdiction in its designated fields. These include terrorist offences, specified offences involving weapons of mass destruction, crimes against humanity, war crimes, and certain offences involving torture or enforced disappearance.

The creation of the PNAT reflects the particular investigative and prosecutorial challenges associated with terrorism and international criminal conduct. Such cases may involve foreign networks, digital evidence, cross-border financial transactions, international cooperation, and security-related information.

The PNAT is a prosecution service rather than a trial court. It directs or coordinates prosecutions within its statutory competence, while the determination of guilt remains the responsibility of the competent criminal court.

7.3. The Parquet national anticriminalité organisée (Pnaco)

A significant recent development is the establishment of the Parquet national anticriminalité organisée (Pnaco), which entered into operation in January 2026. It was created under the legislation adopted in June 2025 to strengthen the national response to organised crime, including major narcotics trafficking networks and other forms of highly structured criminal activity.

The Pnaco is based within the tribunal judiciaire of Paris and is intended to address the most serious forms of organised criminality. Its work includes coordination across national and regional judicial structures and cooperation with European and international partners.

Its remit covers major organised-crime cases, including certain forms of trafficking, exploitation, and complex criminal networks. It is designed to coordinate action from the investigative stage through prosecution and the enforcement of sentences in the cases within its jurisdiction.

The Pnaco does not replace local prosecutors or the JIRS. Instead, it provides a national-level structure for particularly serious organised-crime cases, while the wider judicial system continues to deal with offences falling outside its specific competence. Ministère de la justice

7.4. The Parquet national financier (PNF)

The Parquet national financier is a specialised prosecution service responsible for designated serious financial and economic offences. Its work includes complex corruption, tax-related criminal offences, serious financial misconduct, and offences affecting the integrity of financial markets.

The PNF operates within a specialised framework that allows it to deal with cases of national or international significance. It may coordinate investigations involving corporate structures, cross-border financial transactions, public procurement, and complex ownership arrangements.

As with the PNAT and Pnaco, the PNF is not a court that determines guilt. Its role is prosecutorial. Trial proceedings take place before the criminal court with jurisdiction under the applicable statutory rules.

7.5. Specialised criminal jurisdictions and the ordinary court structure

Specialisation does not eliminate the ordinary criminal hierarchy. A case investigated or prosecuted by a specialised service must still be brought before a court legally competent to hear the offence.

The distinction is important for understanding the French system: specialised prosecution and investigation structures may centralise a case, but they do not independently create a criminal conviction. The judicial determination of guilt and sentence remains subject to the applicable trial-court jurisdiction and procedural safeguards.

8. Criminal justice for minors

French criminal justice distinguishes between adults and minors. This distinction reflects the principle that children and adolescents have different developmental capacities and that criminal proceedings involving minors must take account of their age, maturity, educational needs, and prospects for rehabilitation.

The principal framework is the Code de la justice pénale des mineurs (Code of Criminal Justice for Minors), which entered into force in 2021. It establishes specialised procedures and institutions for dealing with minors accused of criminal offences.

The system is not simply a reduced version of adult criminal justice. It gives particular importance to educational measures, individual assessment, and the protection of the minor’s rights.

8.1. The juge des enfants

The juge des enfants is a specialised judicial officer who performs both protective and criminal functions in relation to minors.

In criminal matters, the judge may deal with certain offences committed by minors and may order measures intended to address the minor’s conduct and circumstances. The judge’s role is not limited to imposing punishment. It may include educational measures and decisions designed to reduce the risk of further offending.

The juge des enfants also has a separate protective jurisdiction concerning minors whose health, safety, or development is at risk. These protective proceedings must be distinguished from criminal proceedings, even though they may involve the same child or family circumstances.

8.2. The tribunal pour enfants

The tribunal pour enfants hears more serious cases involving minors, including certain offences committed by children and adolescents and crimes committed by minors under sixteen.

It is presided over by a professional judge, ordinarily the juge des enfants, and includes two lay assessors. The participation of non-professional assessors reflects the importance attached to educational and social perspectives in juvenile justice.

The court may impose criminal penalties where the law permits, but the juvenile framework gives particular significance to educational measures and the individual circumstances of the minor.

8.3. The cour d’assises des mineurs

The cour d’assises des mineurs is responsible for judging crimes committed by minors aged sixteen to eighteen. Its composition and procedure reflect the special requirements of juvenile criminal justice.

It includes three professional judges and six jurors. The professional judges include judges with particular experience in juvenile matters. The proceedings are adapted to the age and legal status of the accused, and the minor must be assisted by a lawyer.

The court may also deal with an adult co-accused in certain circumstances where the statutory rules governing connected proceedings apply. The participation of an adult in a case involving a minor does not remove the need to apply the special legal framework governing the juvenile accused.

8.4. Confidentiality and protection

Proceedings involving minors are generally subject to restricted publicity. The objective is to protect the minor’s identity, dignity, and prospects for reintegration.

The public nature of justice must therefore be balanced against the special protections applicable to children. The rules are intended to prevent unnecessary exposure and to recognise that a criminal proceeding involving a minor may have long-term consequences for education, family life, and social development. Ministère de la justice+2

9. The public prosecution service: ministère public

The ministère public is central to the operation of French criminal justice. It represents the public interest in the enforcement of criminal law and is responsible for bringing criminal proceedings where the statutory and evidential conditions justify prosecution.

At the level of the tribunal judiciaire, the principal prosecutor is the procureur de la République. The prosecutor is assisted by deputy prosecutors and other members of the prosecution service. At appellate level, the procureur général represents the public prosecution service before the cour d’appel.

9.1. The prosecutor’s role

The prosecutor receives reports of suspected offences, assesses the available information, and decides what action should be taken. Depending on the case, the prosecutor may:

• decide that no prosecution should be brought;
• direct or supervise further investigation;
• initiate criminal proceedings;
• refer the matter for a formal judicial investigation;
• propose an alternative procedure where the law permits;
• bring the case before the competent trial court.

The prosecutor’s decision is guided by the principle of opportunité des poursuites, often translated as prosecutorial discretion. This means that the prosecutor assesses whether prosecution is appropriate in light of the facts, the available evidence, the public interest, and the applicable legal framework.

This discretion is not unlimited. It operates within statutory requirements and is subject to procedural safeguards and judicial oversight. A decision not to prosecute may, in certain circumstances, be challenged or followed by other lawful procedural routes available to victims.

9.2. The prosecutor and judicial independence

The French public prosecution service belongs to the judicial order, but its institutional status differs from that of judges who adjudicate cases. Prosecutors perform a function of public accusation and do not decide whether a defendant is guilty.

This distinction is essential. The prosecutor may request conviction and propose a sentence, but the trial court must independently assess the case. The prosecutor’s submissions are not binding on the court.

The principle of impartial adjudication requires that the judge deciding the case remain independent of the prosecution. The adversarial process allows the defence to challenge the prosecution’s evidence and legal arguments.

9.3. The prosecutor and the police

The prosecutor supervises criminal investigations conducted by the judicial police, subject to the applicable legal framework. Police officers and gendarmes gather evidence, identify suspects, interview witnesses, conduct searches where authorised, and perform other investigative acts.

The investigation is intended to establish both incriminating and exculpatory material. The prosecution must not treat the investigation as a process concerned solely with confirming guilt. The obligation to investigate objectively is important to the fairness and reliability of the proceedings. Ministère de la justice

10. Judicial investigation and the juge d’instruction

In serious and complex criminal cases, French criminal procedure may involve a formal judicial investigation known as information judiciaire. This is conducted by an investigating judge, the juge d’instruction.

The investigating judge is a professional magistrate responsible for conducting a judicial inquiry into the alleged offence. The judge is not a prosecutor and does not act as the trial court. The purpose of the investigation is to establish the relevant facts and determine whether sufficient grounds exist for the case to proceed to trial.

10.1. The investigating judge’s powers

The juge d’instruction may conduct or order investigative measures authorised by law. These can include:

• questioning suspects and witnesses;
• arranging confrontations between individuals;
• ordering expert examinations;
• requesting documents and records;
• authorising or conducting searches within the applicable legal framework;
• examining financial and digital evidence;
• ordering other investigative acts necessary to establish the facts.

The investigation is conducted à charge et à décharge: both incriminating and exculpatory evidence must be considered. This principle is particularly important because the investigating judge is not simply an extension of the prosecution service.

10.2. The status of the person under investigation

A person formally placed under investigation may be designated as mis en examen. This status is distinct from a conviction. It indicates that the investigation has reached a stage at which there are serious or corroborating indications of possible involvement in the alleged offence, as defined by the Code of Criminal Procedure.

A person may also be granted the status of témoin assisté (assisted witness), which provides certain procedural rights where the statutory conditions are met but the requirements for formal examination as a mis en examen have not been satisfied.

The distinction matters because a person under investigation remains presumed innocent. The formal status provides procedural rights and access to legal assistance; it does not establish criminal responsibility.

10.3. Completion of the investigation

At the conclusion of the judicial investigation, the investigating judge may issue an order closing the investigation. Depending on the evidence and applicable legal standards, the judge may:

• issue a non-lieu, meaning that the case will not proceed to trial;
• refer the matter to the correctional court where the alleged conduct constitutes a délit;
• commit the accused for trial before the appropriate criminal court where the alleged conduct constitutes a crime.

The decision is subject to the procedural remedies provided by law. The investigating judge’s role is therefore significant, but the final determination of guilt remains with the trial court.

11. Judicial liberty and detention: the juge des libertés et de la détention

The juge des libertés et de la détention (JLD) is a specialised judicial judge responsible for deciding certain matters involving individual liberty during criminal proceedings.

The JLD’s function is particularly important where the prosecution or investigating authorities seek measures that substantially restrict personal freedom. The judge may be required to decide whether pre-trial detention is justified or whether less restrictive measures are sufficient.

11.1. Pre-trial detention

Pre-trial detention is a serious restriction of liberty because it takes place before a final determination of guilt. It must therefore be justified by statutory conditions and cannot be treated as an automatic consequence of a serious accusation.

Depending on the procedural stage and legal framework, the JLD may examine whether detention is necessary to prevent specified risks, such as interference with evidence, pressure on witnesses, collusion with accomplices, flight, or further offending.

The court must consider whether less restrictive measures, including judicial supervision, could adequately address the relevant risks.

11.2. Judicial supervision and alternatives

French procedure provides alternatives to detention, including contrôle judiciaire (judicial supervision). This may impose obligations or restrictions such as reporting requirements, limitations on travel, restrictions on contact with specified persons, or other measures authorised by law.

The purpose is to ensure the proper conduct of proceedings while avoiding unnecessary deprivation of liberty. The JLD therefore plays an important role in balancing investigative needs, public safety, and individual rights.

12. The stages of criminal proceedings

French criminal proceedings are not a single uninterrupted judicial event. They normally involve several stages, each with a distinct legal purpose.

12.1. Reporting and initial information

Proceedings may begin through a complaint by a victim, a report by a public authority, information received by the police, or the discovery of an offence during another investigation.

A complaint may be submitted to the police, gendarmerie, or public prosecutor. The victim’s report may provide the initial basis for an investigation, although the prosecution service retains responsibility for deciding what action should follow.

12.2. Preliminary investigation

A enquête préliminaire is conducted under the supervision of the public prosecutor. It allows the judicial police to gather evidence and identify the persons potentially responsible.

The police may interview witnesses, examine documents, obtain relevant information, and undertake investigative acts within the limits established by law. More intrusive measures require specific legal authority and may require judicial authorisation.

12.3. Investigation in cases of flagrance

French law also recognises enquête de flagrance, a special form of investigation applicable where an offence is discovered in circumstances satisfying the statutory definition of flagrancy.

The legal framework permits certain investigative powers to be exercised under conditions that differ from those governing an ordinary preliminary investigation. The use of such powers remains subject to procedural limits and the applicable guarantees.

12.4. Prosecution decision

After considering the available evidence, the prosecutor determines the appropriate procedural response. This may include discontinuing the case, pursuing an alternative measure, initiating proceedings before the competent court, or requesting a formal judicial investigation.

A decision to discontinue proceedings (classement sans suite) does not necessarily mean that the alleged conduct has been judicially declared lawful or that the evidence has been tested at trial. It is a prosecutorial decision made within the applicable legal framework.

12.5. Trial

The case is brought before the court with jurisdiction over the relevant category of offence. The trial court examines the evidence, hears the parties, applies the relevant law, and determines whether the prosecution has established criminal responsibility.

The defendant must be given a fair opportunity to understand and contest the allegations. The court must consider the evidence impartially and reach its decision according to the applicable standard of proof.

12.6. Appeal and enforcement

Following judgment, the parties may exercise the remedies available under the Code of Criminal Procedure. If the decision becomes final, the sentence is enforced in accordance with the applicable rules.

The stages are connected, but each has a separate legal function. A police investigation does not establish guilt; a prosecutor’s decision to prosecute does not establish guilt; and a pre-trial detention order is not a sentence. Criminal responsibility is determined by the competent court through lawful proceedings.

13. Procedural rights of defendants

The legitimacy of criminal justice depends not only on the ability of the state to investigate and prosecute offences but also on its obligation to respect the rights of individuals accused of wrongdoing.

French criminal procedure recognises a range of protections grounded in the Constitution, the Code of Criminal Procedure, European Union law where applicable, and the European Convention on Human Rights.

13.1. Presumption of innocence

The presumption of innocence is a fundamental principle. A person accused of an offence must be treated as innocent unless and until guilt is established through lawful proceedings.

The seriousness of the accusation, the existence of a police investigation, or the decision to place someone under formal investigation does not remove this protection.

The burden of establishing criminal responsibility rests on the prosecution. The defendant is not required to prove innocence.

13.2. Right to legal assistance

The right to legal assistance is central to the defence. A person in police custody (garde à vue) must be informed of the right to consult and be assisted by a lawyer, subject to the applicable procedural rules.

The lawyer’s role is especially important where the person is questioned, where statements may be used as evidence, or where detention and investigative measures may affect fundamental rights.

Legal assistance also applies during trial proceedings. In serious criminal cases, representation by a lawyer is compulsory.

13.3. Right to information and access to the case

The accused must be informed of the allegations and given the opportunity to understand the legal and factual basis of the prosecution.

Access to relevant procedural materials is essential to preparing a defence. The defendant and lawyer must be able to examine the evidence and challenge its reliability, legality, or interpretation in accordance with the procedural rules.

13.4. Right to remain silent

The right not to incriminate oneself and the right to remain silent are important protections in criminal proceedings. A suspect cannot be compelled to provide a confession simply because the authorities consider the evidence against them persuasive.

The right to remain silent does not prevent lawful questioning, but it protects the individual against being forced to contribute to their own criminal conviction.

13.5. Fair trial and reasonable time

The right to a fair trial includes the requirement that proceedings be conducted by an independent and impartial tribunal established by law. It also includes the right to have the case heard within a reasonable time.

This requirement is particularly significant in complex criminal cases, where investigations may involve many defendants, extensive digital evidence, international cooperation, and large documentary records.

The French system must balance the need for thorough investigation with the obligation to avoid unjustified procedural delay. Ministère de la justice+1

14. Victims and civil parties in criminal proceedings

French criminal procedure recognises that criminal offences may cause both public harm and individual injury. The prosecution represents the public interest in enforcing criminal law, while victims may seek recognition and compensation for their personal losses.

A victim may participate in proceedings as a partie civile (civil party), subject to the statutory requirements.

14.1. The role of the civil party

The civil party may seek compensation for harm directly caused by the alleged offence. The claim may concern physical injury, psychological harm, property loss, financial damage, or other legally recognised consequences.

The civil party may participate in the criminal proceedings, make submissions concerning the civil claim, and exercise procedural rights within the limits established by law.

The victim’s role must be distinguished from that of the public prosecutor. A victim may seek compensation and participate in the proceedings, but does not replace the prosecution service in representing the public interest.

14.2. Compensation and criminal responsibility

Where the defendant is convicted, the criminal court may also determine the civil claim and order compensation where the legal requirements are satisfied.

The civil claim is concerned with the harm suffered by the victim, while the criminal judgment determines whether the defendant is criminally responsible and what penalty should be imposed.

The two questions are related but conceptually distinct. Criminal punishment is not simply a method of compensating the victim, and civil compensation does not replace the state’s responsibility to enforce criminal law.

14.3. Victim protection

Victims may be entitled to protective measures, information about proceedings, and access to support services. Particular safeguards may apply to victims of sexual violence, domestic violence, trafficking, and other serious offences.

The court may also restrict public access to proceedings where the law permits, especially where publicity would expose a victim to unnecessary harm or compromise protected interests.

15. Appeals and the review of criminal judgments

French criminal justice provides mechanisms for challenging judicial decisions. The nature of the remedy depends on the court that delivered the judgment and the category of offence.

The right to appeal is important because it permits a higher court to review a decision and, where the law allows, reconsider the factual and legal issues.

15.1. Appeals from the tribunal de police

Decisions of the tribunal de police may be challenged through the appeal mechanisms provided by criminal procedure. The availability of an appeal may depend on the nature of the decision and the applicable statutory conditions.

Where an appeal is available, the competent appellate court reviews the matter within the scope of the appeal and the relevant procedural rules.

15.2. Appeals from the tribunal correctionnel

Judgments of the tribunal correctionnel may generally be appealed to the criminal chamber of the cour d’appel. The appeal may be brought by the defendant, the public prosecutor, and, within the limits of their respective rights, the civil party.

The appeal court may examine the issues raised by the appeal and deliver a new decision. Its powers depend on the scope of the challenge and the procedural position of the parties.

15.3. Appeals from the cour criminelle départementale

The cour criminelle départementale is subject to a specific appellate framework. Under the rules applicable to its judgments, an appeal results in a new trial before the competent cour d’assises formation.

This is significant because the appeal is not merely a narrow review of the written judgment. The case is reheard in accordance with the applicable criminal procedure, including the rules governing the presentation and assessment of evidence.

The 2026 reform of the criminal justice framework should be considered when examining the precise rules applicable to an individual case. Ministère de la justice+1

15.4. Appeals from the cour d’assises

A judgment of the cour d’assises may also be challenged by appeal. The case is then reheard by another cour d’assises formation, with the composition and jury numbers applicable to appellate proceedings.

This provides an opportunity for a new examination of the case, rather than limiting the challenge to questions of legal interpretation.

15.5. The Cour de cassation

The Cour de cassation is the highest court in the French judicial order. Its criminal chamber examines appeals on points of law, known as pourvois en cassation.

The Court does not ordinarily conduct a new trial or reassess the facts as if it were another trial court. Its role is to determine whether the lower court correctly applied the law and respected the procedural requirements governing the case.

If the Court identifies a legal error, it may quash the challenged decision. Depending on the circumstances, the case may be referred to another court for reconsideration or dealt with under the applicable procedural rules.

This distinction between appeal and cassation is fundamental. An appeal may involve a new examination of facts and law; cassation principally concerns the legality of the decision and the proper application of procedural and substantive rules.

16. Sentencing and the enforcement of criminal judgments

A criminal judgment does not end the institutional process. Where a defendant is convicted, the sentence must be implemented in accordance with the law. French criminal justice therefore includes specialised judicial functions concerned with the execution and adaptation of penalties.

16.1. The principle of individualised sentencing

The court must determine a sentence within the limits established by legislation. The decision must take account of the nature and circumstances of the offence, the defendant’s personal situation, the degree of responsibility, and the statutory principles governing punishment.

The purpose of sentencing is not confined to imposing a penalty. French criminal law recognises several objectives, including the protection of society, prevention of further offending, rehabilitation, and the reintegration of the convicted person.

The sentence must be proportionate and legally justified. The court cannot impose a penalty that has no basis in legislation or exceeds the applicable statutory maximum.

16.2. The juge de l’application des peines

The juge de l’application des peines (JAP) is responsible for certain judicial decisions concerning the implementation and adaptation of sentences.

The judge may consider matters such as sentence adjustments, conditional release, electronic monitoring, and other measures authorised by law. The precise powers depend on the nature of the sentence and the applicable statutory conditions.

The purpose of sentence enforcement is to ensure that the judgment is implemented lawfully while considering the practical and rehabilitative dimensions of punishment.

16.3. Prison administration and judicial oversight

The administration of prisons is primarily an executive responsibility, but the execution of criminal sentences remains subject to judicial oversight and legal safeguards.

Prisoners retain fundamental rights, subject to lawful restrictions inherent in detention. Questions concerning sentence enforcement, detention conditions, and procedural rights may give rise to judicial proceedings where the applicable legal conditions are satisfied.

The relationship between courts and prison administration demonstrates that criminal justice continues beyond conviction. The state must ensure that punishment is carried out in accordance with the law and that the rights of detained persons are respected.

17. International and European influences on French criminal justice

French criminal procedure is shaped not only by domestic legislation but also by international and European legal obligations.

The European Convention on Human Rights is particularly important. Article 6 protects the right to a fair trial, while Article 5 concerns the right to liberty and security. Article 3 prohibits torture and inhuman or degrading treatment, and Article 8 protects private and family life.

These guarantees influence the interpretation and application of French criminal procedure. They are relevant to police custody, pre-trial detention, the independence and impartiality of courts, access to legal assistance, and the fairness of criminal trials.

17.1. The European Court of Human Rights

The European Court of Human Rights supervises compliance with the European Convention on Human Rights by the states that are parties to it.

Individuals may bring applications against France after satisfying the admissibility requirements, including the requirement to exhaust effective domestic remedies in the ordinary course.

The Court’s judgments may require changes in national practice or legislation where a violation is established. Its case law has influenced French rules concerning detention, police questioning, procedural fairness, and the protection of defendants and victims.

17.2. European Union criminal cooperation

European Union law has also influenced French criminal justice, particularly in cross-border cooperation.

The European Arrest Warrant allows Member States to surrender individuals for prosecution or execution of criminal sentences under a common legal framework. Other instruments facilitate cooperation in the gathering and exchange of evidence, mutual recognition of judicial decisions, and coordination in serious cross-border investigations.

Eurojust supports cooperation between national judicial authorities, while Europol assists law-enforcement cooperation and information exchange. These bodies do not replace national criminal courts, but they contribute to the investigation and prosecution of offences that cross national borders.

17.3. International criminal law

France also participates in the international legal framework governing serious international crimes. The French criminal justice system may exercise jurisdiction over certain offences committed abroad where the statutory conditions are satisfied.

The specialised role of the PNAT in relation to crimes against humanity, war crimes, torture, and enforced disappearance illustrates the interaction between domestic criminal jurisdiction and international criminal law.

Such cases may involve difficult questions of jurisdiction, evidence, immunity, international cooperation, and the relationship between domestic proceedings and international institutions.

18. Contemporary challenges facing French criminal courts

The French criminal justice system must respond to changing patterns of offending, growing evidential complexity, and increasing demands for effective judicial protection.

18.1. Delays and judicial workload

One of the principal challenges is the volume of criminal cases and the time required to investigate and determine them. Complex cases may involve numerous defendants, extensive witness evidence, forensic examinations, financial records, and digital communications.

Delays can affect victims, defendants, witnesses, and public confidence. For defendants, prolonged proceedings may create uncertainty and, in cases involving pre-trial detention, may raise particularly serious liberty concerns.

The right to a hearing within a reasonable time therefore remains an important measure of the effectiveness of criminal justice.

18.2. Organised crime and transnational networks

Organised criminal networks operate across borders and may combine drug trafficking, human exploitation, cybercrime, money laundering, and corruption.

These cases require specialist knowledge, cooperation between police and judicial authorities, and the ability to trace complex financial and digital evidence. The JIRS, PNAT, PNF, and Pnaco reflect the institutional response to these challenges.

18.3. Digital evidence and technological change

Digital evidence has become central to many criminal investigations. Mobile phones, electronic communications, cloud storage, financial platforms, location data, and online activity may all be relevant to establishing the facts.

The use of such material raises questions about authenticity, integrity, privacy, lawful collection, and the rights of the defence. Courts must assess whether digital evidence has been obtained and presented in accordance with the law and whether it is sufficiently reliable to support a finding of guilt.

Artificial intelligence and automated analytical systems may assist in processing large volumes of information, but their use must remain compatible with judicial independence, transparency, the right to challenge evidence, and the principle that a human judicial authority must determine criminal responsibility.

18.4. Victim protection and access to justice

The criminal justice system must ensure that victims can report offences, participate in proceedings, and obtain appropriate protection and compensation.

This is particularly important in cases involving domestic violence, sexual offences, trafficking, and exploitation, where victims may face intimidation, trauma, or practical barriers to participation.

Effective access to justice requires more than formal procedural rights. It also depends on the availability of legal assistance, information, interpretation, support services, and timely judicial decisions.

18.5. Maintaining the balance between public security and individual liberty

Criminal justice necessarily involves the exercise of coercive state powers. Police custody, searches, surveillance, detention, prosecution, and imprisonment may all be necessary in appropriate cases, but they must be grounded in law and subject to effective safeguards.

The central challenge is to ensure that the pursuit of public security does not undermine the principles that give criminal justice its legitimacy. The presumption of innocence, judicial independence, proportionality, and the right to a fair trial are not obstacles to effective enforcement; they are essential conditions of lawful enforcement.

19. Conclusion

The criminal courts of France form a structured system in which jurisdiction is determined primarily by the legal classification and seriousness of the offence. The tribunal de police hears contraventions, the tribunal correctionnel hears délits, and serious crimes are allocated between the cour criminelle départementale and the cour d’assises according to the statutory framework.

The system also includes specialised arrangements for juvenile justice, organised crime, terrorism, and complex financial offences. These structures allow the French state to address different categories of criminal conduct while retaining the basic institutional distinction between investigation, prosecution, adjudication, appeal, and enforcement.

The 2026 legislative changes to the cour criminelle départementale demonstrate that the organisation of criminal justice is not static. Its jurisdiction, composition, and procedural rules evolve through legislation and must be understood by reference to the law in force at the relevant time.

Ultimately, the legitimacy of French criminal justice depends on more than the ability to prosecute and punish. It requires that criminal responsibility be established through fair procedures, that defendants receive effective protection of their rights, that victims have meaningful access to justice, and that judicial decisions remain independent and reasoned. The criminal courts are therefore not merely instruments of state authority; they are institutions through which the rule of law is applied to the most consequential questions of individual responsibility and public protection.

Frequently Asked Questions (FAQs)

1. How are criminal offences classified in France?

French criminal law recognises three categories: contraventions, délits, and crimes. They are classified according to their seriousness and the penalties prescribed by law. The classification determines the competent court and influences the applicable procedural framework.

2. Which court hears minor criminal offences in France?

The tribunal de police hears contraventions committed by adults. It principally imposes fines and may impose supplementary penalties authorised by law, but it does not impose imprisonment for contraventions.

3. What is the difference between a tribunal de police and a tribunal correctionnel?

The tribunal de police hears contraventions, the least serious category of criminal offence. The tribunal correctionnel hears délits, which may carry imprisonment and other more substantial criminal penalties.

4. Which court hears theft and fraud cases in France?

The tribunal correctionnel generally hears theft and fraud cases classified as délits. However, the legal classification and jurisdiction may differ where the offence involves aggravating circumstances or forms part of a more serious criminal accusation.

5. What is the cour criminelle départementale?

It is a criminal trial court composed of five professional judges. Under Article 380-16 of the Code of Criminal Procedure, as amended with effect from 25 July 2026, it hears adults accused of crimes punishable by fifteen or twenty years of criminal imprisonment, subject to statutory conditions.

6. Does the cour criminelle départementale use a jury?

No. It consists of five professional judges and does not include citizen jurors. This distinguishes it from the ordinary cour d’assises.

7. What is the difference between the cour criminelle départementale and the cour d’assises?

The cour criminelle départementale hears specified serious crimes at first instance through a panel of five professional judges. The cour d’assises hears crimes outside that court’s statutory jurisdiction and includes professional judges and citizen jurors in its ordinary first-instance formation.

8. Which court hears murder cases in France?

The competent court depends on the legal classification and the penalty prescribed for the offence. Serious murder or assassination cases will ordinarily be heard by the cour d’assises, while the precise jurisdiction must be determined under the relevant provisions of the Penal Code and Code of Criminal Procedure.

9. Can a criminal case be heard by a single judge in France?

Yes. Certain cases before the tribunal correctionnel may be heard by a single professional judge under Article 398-1 of the Code of Criminal Procedure. The ordinary formation remains a panel of three professional judges.

10. What does the public prosecutor do in French criminal proceedings?

The procureur de la République represents the public prosecution service at first-instance level. The prosecutor assesses suspected offences, directs or supervises investigations, decides whether to prosecute, and presents the prosecution’s case before the court.

11. Does the French prosecutor decide whether the defendant is guilty?

No. The prosecutor may request conviction and propose a penalty, but only the competent court can determine criminal responsibility. The trial court must assess the evidence independently and respect the presumption of innocence.

12. What is a juge d’instruction?

A juge d’instruction is an investigating judge responsible for conducting a formal judicial investigation in cases referred for information judiciaire. The judge gathers evidence both for and against the person under investigation and determines whether the case should proceed to trial or be closed.

13. Is everyone investigated by a French judge formally accused?

No. French procedure distinguishes between different procedural statuses. A person may be designated as mis en examen or may have the status of témoin assisté, depending on the evidence and statutory conditions. Neither status is a conviction.

14. What is the juge des libertés et de la détention?

The juge des libertés et de la détention (JLD) is a specialised judicial judge who decides certain matters involving personal liberty during criminal proceedings, particularly applications concerning pre-trial detention and related restrictions.

15. What is garde à vue?

Garde à vue is a form of police custody under French criminal procedure. It permits the temporary detention of a person suspected of an offence where the statutory conditions are satisfied. The person must be informed of their rights, including the right to legal assistance.

16. Can a victim participate in a French criminal trial?

Yes. A victim may constitute themselves as a partie civile where the legal requirements are met. This allows the victim to participate in the proceedings and seek compensation for harm directly caused by the alleged offence.

17. Are criminal trials in France public?

As a general rule, criminal hearings are public. However, legislation permits restrictions, including closed hearings in certain cases involving minors, sexual offences, privacy, or other protected interests.

18. How are minors tried in France?

Minors are subject to a separate criminal justice framework under the Code de la justice pénale des mineurs. Depending on the age of the minor and the seriousness of the offence, proceedings may take place before the juge des enfants, tribunal pour enfants, or cour d’assises des mineurs.

19. What is the JIRS?

The juridictions interrégionales spécialisées are specialised judicial structures responsible for particularly complex organised-crime and financial-crime cases. They allow investigations and prosecutions to be coordinated across several judicial districts.

20. What is the difference between the PNAT, PNF, and Pnaco?

The PNAT specialises in terrorism and specified serious international crimes; the PNF handles designated serious financial and economic offences; and the Pnaco coordinates the most serious organised-crime cases at national level. All three are prosecution services, not trial courts.

21. Can a defendant appeal a criminal conviction in France?

Yes, subject to the applicable procedural rules. Decisions of criminal courts may be challenged through appeal where legislation permits. The competent appellate court and the scope of review depend on the court that delivered the original judgment.

22. What does the Cour de cassation do in criminal cases?

The criminal chamber of the Cour de cassation reviews whether the lower court correctly applied the law and complied with procedural requirements. It does not ordinarily conduct a new examination of the facts.

23. What happens after a person is convicted?

The sentence is enforced under the applicable legal framework. The juge de l’application des peines may decide certain matters concerning sentence adjustments, conditional release, electronic monitoring, and other measures authorised by law.

24. Does French criminal law apply to offences committed outside France?

In certain circumstances, yes. French criminal law may apply to conduct committed abroad where statutory rules concerning territoriality, nationality, the nature of the offence, or other jurisdictional grounds are satisfied. International cooperation may also be necessary to investigate and prosecute such cases.

25. Which laws govern criminal proceedings in France?

The principal legislation consists of the Penal Code and the Code of Criminal Procedure. The Constitution, applicable European Union law, the European Convention on Human Rights, and relevant international treaties also shape the legal framework.
