Introduction
Criminal law does not punish only completed crimes.
In some circumstances, a person can be held criminally responsible even when the intended crime was never completed.
A person may attempt to rob a bank but flee before obtaining any money. A person may shoot at another person intending to kill but miss. A person may break into a building intending to commit a felony but be arrested before reaching the intended target.
These situations raise a fundamental question:
When does preparation for a crime become a criminal attempt?
The answer is important because criminal law must balance two competing principles.
On one side, the law has an interest in preventing serious crimes before they are completed.
On the other, criminal punishment should not ordinarily be imposed merely because a person had a bad idea, entertained a criminal intention, or took innocent preparatory steps.
The law of attempt draws a boundary between thought, preparation, and punishable criminal conduct.
An attempt is generally understood as an inchoate offense: a crime that is begun but not completed. Cornell’s Legal Information Institute describes attempt as an offense involving an intent to commit a crime combined with conduct that moves sufficiently toward its commission. Cornell Legal Information Institute — Attempt
Attempt therefore occupies an important position between criminal intention and completed criminal conduct.
1. What Is an Attempt?
An attempt occurs when a person intends to commit a particular crime and takes sufficiently substantial steps toward committing it, but the intended crime is not completed.
The basic structure is:
Criminal intent + criminal conduct toward completion + failure to complete the crime = attempt
For example:
A intends to rob a bank.
A purchases a disguise, drives toward the bank, enters the building carrying a weapon, and approaches the teller.
Before A can demand money, the police intervene.
The robbery was not completed.
But A’s conduct may constitute an attempted robbery.
The important question is not simply whether A intended to commit the robbery.
The question is whether A went far enough beyond preparation to become criminally liable for an attempt.
2. Attempt as an Inchoate Offense
Attempt belongs to the category of inchoate offenses.
An inchoate offense criminalizes conduct directed toward the commission of another crime even though the target crime has not been completed.
Other commonly recognized inchoate offenses include:
- solicitation;
- conspiracy; and
- attempt.
These offenses differ from completed crimes because the intended criminal result may never occur.
Attempt is therefore a form of preventive criminal liability.
The law intervenes before the completed harm occurs.
3. Why Does Criminal Law Punish Attempts?
At first glance, punishing an unsuccessful crime might seem strange.
Suppose A intends to kill B but misses.
B survives.
Why should A be punished for homicide?
The answer is that A may have created a substantial danger even though the final result did not occur.
Attempt law recognizes that criminal responsibility can arise from:
- dangerous conduct;
- culpable intention;
- substantial movement toward a criminal objective; and
- the resulting threat to protected interests.
The law therefore does not need to wait until the intended victim is actually harmed in every case.
Attempt law serves several functions:
- Prevention — intervening before the crime is completed.
- Deterrence — discouraging people from beginning criminal conduct.
- Protection — protecting victims and society from developing criminal threats.
- Moral accountability — recognizing culpable conduct even when circumstances prevent completion.
- Law enforcement — allowing intervention before the intended crime reaches completion.
4. The Basic Elements of Attempt
Although precise formulations differ by jurisdiction, attempt generally requires several components.
1. The defendant had the required criminal intent.
2. The defendant intended to commit the target crime.
3. The defendant took conduct sufficiently beyond mere preparation.
4. The defendant’s conduct was directed toward completion of the offense.
5. The target crime was not completed.
These elements must be analyzed carefully because attempt is highly dependent on the specific offense and jurisdiction.
5. Specific Intent and Attempt
Mens rea is particularly important in attempt cases.
A person generally cannot accidentally attempt a crime.
Attempt ordinarily requires an intention to commit the target offense.
This is one reason attempt is closely connected to the law of specific intent.
Cornell explains that specific intent refers to a mental state in which the actor intends a particular consequence or objective beyond merely engaging in the prohibited conduct. Cornell Legal Information Institute — Specific Intent
Consider attempted murder.
A person may recklessly fire a gun without intending to kill anyone.
That conduct may constitute another offense.
But attempted murder ordinarily requires proof that the defendant intended to kill.
The absence of the intended result does not eliminate the need for the required mens rea.
6. Attempt Requires Intent Toward the Target Crime
Suppose A wants to frighten B.
A fires a gun into the air.
A never intended to kill B.
If the jurisdiction requires intent to kill for attempted murder, A’s conduct does not become attempted murder merely because the conduct was dangerous.
The prosecution must establish the mental state required for the attempted offense.
This principle is crucial:
Attempt liability generally focuses on what the defendant intended to accomplish, not merely on how dangerous the conduct happened to be.
7. Preparation vs. Attempt
The most difficult question in many attempt cases is:
When has the defendant gone far enough?
Criminal law must distinguish between preparation and attempt.
Preparation
The defendant is getting ready to commit a crime.
Attempt
The defendant has crossed the legal threshold into conduct sufficiently directed toward committing the crime.
For example:
A plans to rob a bank.
A researches the bank’s security system.
This is preparation.
A then enters the bank carrying a weapon and approaches the teller.
This is much closer to attempt.
The exact dividing line varies by jurisdiction.
8. The Last Act Test
Historically, some courts asked whether the defendant had performed the last act necessary to complete the crime.
Under this approach, attempt liability generally did not arise until the defendant had reached the final stage before completion.
The problem is obvious.
Waiting until the last possible moment could prevent law enforcement from intervening until the danger had become extremely serious.
Modern law therefore often uses broader approaches.
9. The Dangerous Proximity Test
Another approach asks whether the defendant’s conduct came sufficiently close to the completed crime.
This is sometimes described as dangerous proximity.
The closer the defendant came to completion, the stronger the argument for attempt.
For example:
A points a loaded gun at B and pulls the trigger.
If the gun malfunctions, A has moved extremely close to completing the intended killing.
By contrast:
A buys a gun and thinks about killing B next year.
That is much more remote.
The proximity approach therefore examines the distance between preparation and completion.
10. The Unequivocality Approach
Another approach focuses on whether the defendant’s conduct clearly demonstrates criminal purpose.
The idea is that conduct should not constitute attempt unless it strongly indicates what the defendant intended to accomplish.
For example:
A walks toward a bank carrying an ordinary backpack.
That conduct is ambiguous.
A walks toward a bank wearing a disguise, carrying a weapon, and carrying a note demanding money.
The conduct is much more indicative of an intended robbery.
The more unequivocal the conduct, the stronger the attempt argument.
11. The Substantial Step Test
Modern American criminal law is strongly influenced by the Model Penal Code’s substantial-step approach.
Under the Model Penal Code, conduct may constitute an attempt when it represents a substantial step toward commission of the planned crime and strongly corroborates the actor’s criminal purpose.
Cornell’s Legal Information Institute identifies the Model Penal Code as an influential framework for American criminal law. Cornell Legal Information Institute — Model Penal Code
Examples of substantial steps can include:
- lying in wait for the intended victim;
- searching for or following the victim;
- enticing the victim to a particular location;
- unlawfully entering a location where the crime is intended to occur;
- possessing specially designed materials necessary for the crime; or
- reconnoitering the place where the offense is planned.
The conduct must be sufficiently connected to the criminal purpose.
12. Why the Substantial-Step Test Matters
The substantial-step approach allows criminal law to intervene before the final act.
This is especially important for serious offenses.
Suppose A plans to assassinate B.
A:
- obtains a weapon;
- studies B’s schedule;
- travels to B’s workplace;
- waits in a concealed position; and
- prepares to shoot.
Under a strict last-act approach, A might not have committed attempt until pulling the trigger.
Under a substantial-step approach, A may already have crossed the line into attempt.
The law can therefore intervene before the intended victim is actually attacked.
13. Conduct Must Strongly Corroborate Criminal Purpose
The substantial-step test does not mean that every preparatory act is criminal.
The conduct should strongly corroborate the defendant’s criminal purpose.
Buying a knife is ordinarily innocent.
Buying a knife while simultaneously stalking a particular victim and waiting outside that person’s home may provide much stronger evidence of criminal intent.
Context therefore matters.
The same physical act can have very different legal significance depending on the surrounding circumstances.
14. Attempt Requires a Specific Criminal Objective
Attempt liability is normally tied to a particular target crime.
A person does not simply “attempt to commit a crime” in the abstract.
The prosecution generally identifies the offense the defendant intended to commit.
For example:
- attempted murder;
- attempted robbery;
- attempted burglary;
- attempted arson;
- attempted theft.
The mental state must correspond to the target offense.
15. Factual Impossibility
One of the most famous attempt issues is factual impossibility.
Suppose A intends to kill B.
A fires a gun at B while believing the gun is loaded.
The gun is actually unloaded.
The intended killing is factually impossible.
Can A nevertheless be guilty of attempted murder?
Generally, factual impossibility does not necessarily prevent attempt liability.
The defendant’s conduct can demonstrate a genuine criminal intent even though an unknown factual circumstance prevented completion.
The law therefore may ask:
What did the defendant believe the circumstances to be?
rather than:
Would the crime actually have succeeded under the circumstances as they really existed?
16. Factual Impossibility Example
A reaches into B’s empty pocket intending to steal a wallet.
B has no wallet.
A cannot actually steal anything.
Nevertheless, A may have attempted theft because the failure resulted from a factual circumstance—the absence of property—not from a lack of criminal purpose.
Similarly:
A shoots at B intending to kill.
The gun is unloaded.
A may still face attempted murder liability where the jurisdiction recognizes such liability.
17. Legal Impossibility
Legal impossibility is different.
Legal impossibility may arise when the defendant’s intended conduct, even if completed exactly as intended, would not constitute the crime.
For example, suppose A performs conduct believing it is criminal, but the conduct is actually lawful.
Historically, some jurisdictions treated legal impossibility as a defense to attempt.
Modern approaches have often narrowed the distinction between factual and legal impossibility.
The precise treatment varies considerably by jurisdiction.
This is an area where students should be cautious about treating old common-law rules as universal modern law.
18. Abandonment and Renunciation
Another important issue is what happens when the defendant voluntarily stops.
Suppose A intends to rob a store.
A enters the store, approaches the cash register, and then changes their mind and leaves.
Can A argue:
“I abandoned the crime, so there is no attempt.”
The answer depends on the jurisdiction.
Some jurisdictions recognize voluntary abandonment or renunciation as a defense under certain circumstances.
The Model Penal Code provides a particularly influential formulation.
The defendant generally must have abandoned the criminal effort completely and voluntarily, rather than stopping because success became impossible or because the defendant feared arrest.
19. Voluntary vs. Involuntary Abandonment
This distinction is critical.
Voluntary abandonment
“I changed my mind. I no longer want to commit the crime.”
Involuntary abandonment
“I stopped because the police arrived.”
Or:
“I stopped because the victim escaped.”
Or:
“I stopped because I realized the alarm system was too difficult to defeat.”
The second category is less likely to qualify for an abandonment defense under approaches requiring genuine voluntary renunciation.
The law is generally reluctant to reward a defendant for stopping only because the crime has become difficult or dangerous.
20. Abandonment After an Attempt
A particularly important question is whether abandonment can erase liability once an attempt has already been completed.
Suppose A takes a substantial step toward murder but then changes their mind.
Some jurisdictions may recognize voluntary abandonment as a defense.
Others may limit the defense or apply specific statutory requirements.
The timing and legal consequences of abandonment therefore depend heavily on the governing law.
Students should never assume that “I stopped” automatically eliminates attempt liability.
21. Impossibility and Attempt
Impossibility demonstrates why attempt law focuses heavily on the defendant’s conduct and mental state.
Consider two people.
Person A
Intends to kill B and shoots at B, but the gun is unloaded.
Person B
Does not intend to kill anyone but accidentally fires an unloaded gun.
The physical result is identical:
Nobody dies.
But the legal analysis is completely different.
Person A may have attempted murder.
Person B has not.
The difference is criminal intent.
22. Attempt and Concurrence
Attempt also requires the relationship between conduct and mental state to be sufficiently established.
The defendant must possess the required criminal intent while taking the conduct that constitutes the attempt.
This reflects the broader principle of concurrence between actus reus and mens rea.

A person cannot ordinarily be convicted of attempting a crime simply because they once intended to commit it.
The criminal conduct must occur in connection with the required mental state.
23. Attempted Crimes That Require a Result
Some crimes require a particular result.
Attempt law allows liability even when the result never occurs.
For example:
Completed murder
Intent to kill + conduct + death.
Attempted murder
Intent to kill + substantial step toward killing + no death.
This is one of the central functions of attempt law.
It allows criminal law to address dangerous conduct before the final result occurs.
24. Attempted Crimes That Do Not Require a Completed Result
Attempt can also apply to offenses where the defendant begins conduct directed toward the prohibited offense but fails to complete it.
For example:
A attempts to burglarize a building but is arrested before entering.
The precise offense classification depends on the jurisdiction’s burglary statute and the elements of the offense.
Attempt law therefore operates in conjunction with the substantive criminal law.
One must first understand the target offense before determining what constitutes an attempt to commit it.
25. Defenses to Attempt
Attempt liability can raise several possible defenses.
Depending on the jurisdiction, these may include:
- lack of intent;
- failure to take a sufficient step;
- abandonment or renunciation;
- legal impossibility;
- factual circumstances negating an element of the target offense;
- lack of causation where causation is required for the attempted offense; and
- constitutional or statutory defects in the underlying criminal law.
The availability of each defense depends on the jurisdiction and offense.
26. Lack of Intent
Because attempt ordinarily requires intent toward the target crime, lack of the required intent can defeat an attempt charge.
Suppose A fires a gun merely to scare B.
A did not intend to kill B.
A may be guilty of another offense, but attempted murder may fail if intent to kill is required.
The prosecution therefore cannot simply prove dangerous conduct.
It must establish the mental state required for the attempted offense.
27. Insufficient Conduct
A defendant may also argue:
“I never went beyond preparation.”
Suppose A purchases a disguise and a weapon but never travels to the intended crime scene.
Depending on the jurisdiction, that may be insufficient for attempt.
By contrast, if A travels to the scene, waits for the victim, and begins executing the plan, the prosecution has a much stronger case.
The central issue is whether the defendant crossed the jurisdiction’s legal threshold.
28. Attempt and the Principle of Legality
Attempt law must also respect the principle of legality.
Criminal liability should not be based on vague or unpredictable standards.
People should be able to understand when conduct becomes criminal.
This is particularly important because attempt law criminalizes conduct before the intended offense has been completed.
The further the law moves away from completed harm, the more important clear boundaries become.
Cornell’s Legal Information Institute explains the legality principle as requiring criminal laws to provide adequate notice of prohibited conduct and limiting retroactive criminalization. Cornell Legal Information Institute — Legality
29. Attempt and the First Amendment
Attempt liability can occasionally intersect with constitutional protections involving speech.
A person can express a criminal thought without necessarily committing an attempt.
For example:
“I want to rob that bank someday.”
That statement alone ordinarily does not establish attempted robbery.
But speech can become evidence of criminal purpose when combined with substantial conduct.
The distinction is between:
expression of an idea
and
conduct demonstrating execution of a criminal plan.
The precise constitutional boundaries depend on the circumstances and applicable law.
30. Attempt and Law Enforcement Intervention
Attempt law has an important relationship with preventive policing.
The state does not necessarily need to wait until the defendant completes the intended offense.
Suppose police discover that A intends to assassinate B.
A has:
- acquired a weapon;
- followed B;
- studied B’s movements;
- positioned themselves near B’s home; and
- begun waiting for an opportunity to attack.
Intervention at this stage may prevent the completed crime.
Attempt law provides a legal framework for determining whether the defendant has already crossed the threshold into criminal conduct.
31. Attempt and the Completed Crime
A defendant generally cannot be convicted of both an attempt and the completed target offense as though they were two entirely independent crimes arising from the same conduct, although the precise treatment depends on jurisdiction and statutory structure.
Once the intended offense is completed, the attempt has ordinarily merged into the completed offense for many purposes.
For example:
Attempted robbery → completed robbery
The completed robbery generally becomes the principal offense.
The exact rules concerning merger and sentencing vary by jurisdiction.
32. Attempt and Multiple Crimes
A single course of conduct can potentially involve multiple criminal offenses.
Suppose A attempts to rob B and assaults B during the attempt.
Depending on the jurisdiction, A may face liability for:
- attempted robbery; and
- assault or another completed offense.
The fact that the target crime was not completed does not necessarily eliminate liability for other crimes that were completed during the attempt.
33. Attempt and Causation
Attempt also connects to the causation principles discussed earlier in criminal law.
When the intended result does not occur, ordinary result-based causation may be absent.
That is one reason attempt is analytically different from a completed result crime.
Suppose A shoots at B intending to kill.
A misses.
There is no death.
Therefore, A cannot be guilty of completed homicide on the basis of B’s death.
But A may be guilty of attempted murder because the law of attempt focuses on the defendant’s intent and conduct directed toward the intended result.
Thus:
No completed result does not necessarily mean no criminal liability.
34. Attempt and Transferred Intent
Transferred intent can also create complicated attempt questions.
Suppose A intends to kill B but shoots at B and misses.
The bullet strikes C instead.
If C survives, A may face liability for attempted murder of B and potentially other offenses concerning C.
The exact treatment depends on jurisdiction.
The important point is that attempt liability is based on the criminal objective and the conduct undertaken to accomplish it.
35. Attempt and Mistake of Fact
A mistake of fact can affect attempt liability depending on what the defendant believed and what the target offense requires.
Suppose A takes a coat believing it belongs to B.
The coat actually belongs to A.
If A genuinely intended to steal the coat, the law of impossibility may become relevant.
The defendant’s belief about the circumstances can matter greatly.
Attempt doctrine therefore sometimes asks:
What crime did the defendant believe they were committing, and what circumstances prevented completion?
36. Attempt and Mistake of Law
Mistake of law is generally more difficult.
Suppose A believes an act is criminal when it is actually lawful.
Can A be convicted of attempting a crime?
Under traditional principles, criminal law generally does not punish a person merely because they mistakenly believe lawful conduct is illegal.
This can become a question of legal impossibility.
Modern attempt doctrines vary, however, so the governing statute and case law must be consulted.
37. Attempt and Strict Liability Offenses
Attempt can become especially complicated when the target offense is a strict-liability offense.
If the completed crime does not require a particular mens rea, does an attempt require the defendant to possess an intent that the completed offense itself does not require?
Different legal systems and statutes can answer this differently.
The important principle is that attempt doctrine does not operate independently of the target offense.
The court must determine:
- what the completed offense requires;
- what mental state attempt requires; and
- whether the legislature has created a specific attempt rule.
38. The Moral and Philosophical Problem of Attempt
Attempt raises a deeper question about criminal responsibility.
Should we punish someone for what they almost did?
Consider two people.
Person A
Attempts to kill someone but misses.
Person B
Intends to kill someone but never acts.
Their thoughts may be equally disturbing.
Their legal responsibility is not.
Why?
Because criminal law generally distinguishes between:
thought
preparation
attempt
completion
Attempt law therefore reflects the idea that criminal responsibility requires more than a guilty mind.
At the same time, the law recognizes that sufficiently dangerous conduct should not always be allowed to continue until the intended victim is actually harmed.
Attempt occupies the difficult middle ground between those principles.
39. The Preparation–Attempt Continuum
Rather than imagining an absolute dividing line, it is often useful to visualize a continuum:
Thought → Planning → Preparation → Substantial Step → Attempt → Completion
The further the defendant moves toward completion, the stronger the case for criminal attempt becomes.
For example:
Thought
“I want to rob a bank.”
Usually no criminal liability.
Planning
“I will rob the bank next Friday.”
Usually no attempt.
Preparation
Buying a disguise and studying the bank.
Potentially still preparation.
Substantial step
Traveling to the bank with the disguise, weapon, and plan.
Potential attempt.
Attempt
Entering the bank and beginning execution of the robbery.
Strong attempt.
Completion
Obtaining the money through the elements of robbery.
Completed robbery.
This continuum helps explain why attempt cases are often fact-specific.
40. A Practical Framework for Attempt Problems
When analyzing an attempt case, use the following sequence.
Step 1: Identify the target offense
What crime did the defendant allegedly intend to commit?
Step 2: Identify the required mens rea
What mental state does that offense require?
Step 3: Determine the defendant’s actual intent
Did the defendant possess the required criminal purpose?
Step 4: Identify the defendant’s conduct
What did the defendant actually do?
Step 5: Separate preparation from execution
Was the defendant merely preparing, or had the criminal plan begun to be executed?
Step 6: Apply the jurisdiction’s attempt test
Was the conduct:
- sufficiently close to completion;
- a substantial step;
- unequivocally criminal; or
- otherwise sufficient under the governing law?
Step 7: Examine impossibility
Did an unknown factual circumstance prevent completion?
Step 8: Examine abandonment
Did the defendant voluntarily and completely renounce the criminal purpose?
Step 9: Determine whether another crime was completed
The defendant may have committed a separate offense even if the target crime was not completed.
Step 10: Apply the relevant statute and precedent
Attempt law varies significantly between jurisdictions.
41. Common Mistakes
Mistake 1: Thinking criminal intent alone is enough
A criminal thought ordinarily does not constitute an attempt.
Mistake 2: Treating every preparatory act as an attempt
Buying equipment or making plans does not automatically cross the legal threshold.
Mistake 3: Assuming the defendant must perform the final act
Modern attempt law often allows liability before the last act.
Mistake 4: Assuming impossibility always defeats attempt
Factual impossibility generally does not automatically prevent attempt liability.
Mistake 5: Assuming abandonment always eliminates liability
Abandonment rules vary, and voluntary renunciation is generally treated differently from stopping because of police intervention or practical difficulty.
Mistake 6: Ignoring mens rea
Dangerous conduct without the required criminal intent may not constitute the attempted offense.
Mistake 7: Treating attempt law as identical everywhere
The threshold for attempt varies among jurisdictions.
Mistake 8: Forgetting the target offense
The elements of the attempted crime must be identified before attempt liability can be analyzed.

Frequently Asked Questions
What is an attempt in criminal law?
An attempt occurs when a person intends to commit a crime and takes sufficiently substantial conduct toward committing it but does not complete the intended offense.
Is criminal intent alone enough for attempt?
Generally, no. Attempt ordinarily requires both the required criminal intent and conduct that crosses the jurisdiction’s threshold beyond mere preparation.
What is the difference between preparation and attempt?
Preparation involves getting ready to commit a crime. Attempt involves conduct sufficiently directed toward the actual commission of the crime.
What is a substantial step?
A substantial step is conduct that goes beyond mere preparation and strongly corroborates the defendant’s criminal purpose under the Model Penal Code approach.
Can someone be guilty of attempted murder if nobody is injured?
Yes. Attempted murder generally focuses on the defendant’s intent to kill and conduct sufficiently directed toward killing. The absence of the victim’s death is what distinguishes the attempt from completed murder.
Does factual impossibility prevent an attempt conviction?
Generally, factual impossibility does not automatically prevent attempt liability. For example, attempting to shoot someone with an unloaded gun may still constitute attempted murder if the defendant believed the gun was loaded and intended to kill.
Is legal impossibility a defense?
Historically, legal impossibility was often recognized as a defense. Modern jurisdictions differ in how they treat the distinction between factual and legal impossibility.
Can abandonment be a defense?
Potentially. Some jurisdictions recognize voluntary abandonment or renunciation, but the requirements vary. Stopping because of fear of arrest or because the crime has become difficult is generally treated differently from genuinely abandoning the criminal purpose.
Can a person be guilty of attempt and another completed crime?
Yes. An unsuccessful attempt may involve other completed offenses, such as assault, weapons offenses, or unlawful entry, depending on the facts and jurisdiction.
Why does criminal law punish attempts?
Attempt law allows the legal system to intervene before serious crimes are completed, while requiring more than mere criminal thoughts or intentions.
Conclusion
The law of attempt occupies one of the most important boundaries in criminal law.
A person can think about committing a crime without becoming criminally liable for the thought. A person can sometimes prepare to commit a crime without having committed an attempt. But once the person intentionally moves sufficiently beyond preparation and begins executing the criminal plan, the law may recognize an independent offense even though the intended crime ultimately fails.
That boundary is not always easy to draw.
A person buying a weapon may be doing something entirely lawful.
A person buying a weapon, stalking a particular victim, traveling to the victim’s home, waiting outside, and preparing to attack is in a very different legal position.
The difference is not simply the existence of a criminal thought.
It is the combination of criminal intent and sufficiently advanced conduct.
Attempt law therefore embodies a careful compromise.
On one side is the principle that criminal law should not punish people merely for what they think.
On the other is the recognition that society should not have to wait until a murder, robbery, arson, or other serious offense is successfully completed before the law can intervene.
The doctrine of attempt creates the legal space between those extremes.
The central question is ultimately:
Has the defendant merely contemplated a crime, or has the defendant crossed the line into conduct that demonstrates a genuine and sufficiently advanced effort to commit it?
Once that question is answered, the remaining issues—mens rea, substantial step, impossibility, abandonment, and defenses—allow the law to determine whether the defendant should be held criminally responsible for the unsuccessful offense.
Attempt therefore represents a fundamental principle of modern criminal law:
The law may punish a sufficiently advanced criminal endeavor even when the intended crime ultimately fails—but it must draw that line carefully enough to distinguish criminal conduct from criminal thought.

Contract Law
10 questions, new every day. See how many you get right — then come back tomorrow for a new category.
Question 1 of 10
Generally, when can an offeror revoke an offer?
Offers are generally revocable at will before acceptance (subject to real exceptions, like option contracts or firm offers for the sale of goods) — the offeror just has to actually get the revocation to the offeree before they accept.
Question 2 of 10
What is the "mirror image rule"?
Under the mirror image rule, an acceptance that changes or adds terms is not a true acceptance at all — it is legally treated as a counteroffer, which the original offeror is then free to accept or reject.
Question 3 of 10
Contracts for the sale of goods are generally governed by which body of law in the U.S.?
The UCC (adopted, with variations, in every U.S. state) governs contracts for the sale of goods, with somewhat different rules than the common law that governs contracts for services or real estate.
Question 4 of 10
What does the "Statute of Frauds" require?
The Statute of Frauds requires specific categories — real estate sales, contracts that can't be performed within a year, and a few others — to be in writing. Most everyday contracts don't need this.
Question 5 of 10
What is "undue influence" as a contract defense?
Undue influence typically arises where one party is in a position of trust or dominance over another (like a caregiver over an elderly, dependent person) and uses that position to unfairly pressure them into an agreement.
Question 6 of 10
What is "anticipatory repudiation"?
When a party clearly announces in advance that they will not perform, the other side generally does not have to wait for the actual performance date — they can treat the contract as breached immediately and pursue remedies right away.
Question 7 of 10
What is the legal effect of a counteroffer?
A counteroffer kills the original offer — the original offeror can no longer simply accept their own original terms once a counteroffer has been made, unless the original offer is renewed.
Question 8 of 10
What is the "implied warranty of merchantability"?
Under the UCC, when a merchant sells goods, the law automatically implies a promise that those goods are reasonably fit for the ordinary purposes they are used for — no specific statement from the seller is required to create it.
Question 9 of 10
What does a contract's "choice of law" clause specify?
In deals crossing state or national lines, a choice of law clause lets the parties agree in advance on which jurisdiction's legal rules will apply to interpreting and enforcing the contract, adding predictability to the relationship.
Question 10 of 10
What is a "merger" or "integration" clause in a contract?
A merger/integration clause signals the written document is meant to be the entire deal — this triggers the parol evidence rule, generally barring earlier oral or written statements from being used to contradict the final written terms.
