Criminal Law Flashcards
Define Actus Reus
An Actus Reus is the voluntary physical act (i.e. bodily movement) required to commit a given crime.
It is a required component of every common law crime along with mens rea.
Omission as Actus Reus
A failure to act can constitute an actus reus IF:
(1) D had a specific duty to act;
(2) D had knowledge of facts giving rise to the duty; and
(3) It was reasonably possible for D to perform the duty
Define Mens Rea
The mental element required AT THE TIME a crime was committed (i.e. the intent element).
There are three forms of mens rea that differ by crime:
(1) Specific Intent
(2) General Intent
(3) Malice
Note that in cases of Strict Liability and Vicarious Liability, there is not a mens rea requirement.
Specific Intent (Mens Rea)
D must have a specific intent or objective to commit the given crime (i.e. they acted intending to commit the crime).
Specific intent can never be inferred; it must be proven.
D can raise the defenses of mistake of fact and voluntary intoxication against Specific Intent crimes.
(1) Attempt
(2) Larceny & Robbery
(3) Forgery
(4) False pretenses
(5) Embezzlement
(6) Conspiracy
(7) Assault
(8) Burglary
(9) First Degree Murder
(10) Solicitation
General Intent (Mens Rea)
D must be aware of his actions and any attendant circumstances.
General intent can be inferred from the act itself.
(1) Battery
(2) Rape
(3) Kidnapping
(4) False Imprisonment
Malice (Mens Rea)
D acts with reckless disregard or undertakes an obvious risk which expectedly leads to a harmful result.
(1) Arson
(2) Common Law Murder
Strict Liability
Crimes where there is no intent or awareness requirement (i.e. no mens rea requirement)
(1) Statutory Rape
(2) Regulatory Crimes
(3) Administrative Crimes
(4) Morality Crimes (bigamy/polygamy)
Vicarious Liability
When a person who did not commit a crime is held liable for the criminal conduct of another.
Same as respondeat superior arising with relation to employment or business associations.
MPC Mens Rea Standards
Subjective Standards:
(1) Purposely (i.e. acting purposely with the conscious objective to engage in certain conduct or cause a certain result)
(2) Knowingly (i.e. acting with the awareness that certain conduct is particular or is very likely to cause a particular result)
(3) Recklessly (i.e. consciously taking substantial or unjustifiable risk)
Objective Standard:
(1) Negligence (i.e. fails to become aware of a substantial or unjustifiable risk)
Note: MBE usually tests common law and will specify when to use MPC.
Concurrence Requirement
D’s criminal act (Actus Reus) and the requisite intent (Mens Rea) for the crime must coincide.
i.e. D intends to murder P at P’s home, but then accidentally runs P over on the way there. Not Murder because the act and intent did not coincide.
Causation Requirement
D’s conduct must be BOTH the cause-in-fact and the proximate cause of the crime committed.
Note: MBE often tests Causation when it comes to homicide crimes.
Cause-in-fact
but for D’s conduct, the result would not have occurred.
Note: Homicide/Manslaughter - hastening an inevitable death is enough
Proximate Cause
the actual result is the natural and probable consequence of D’s conduct even if it did not occur exactly as expected.
Superseding Factors break the chain of causation
Intervening Acts must be entirely unforeseeable to shield D from liability (i.e. refusal of medical treatment or negligence by a third party doctor are foreseeable).
Transferred Intent Doctrine
D intended the harm caused but caused it to a different victim/object than intended.
Applies re: homicide, battery, and arson. (NOT ATTEMPT!)
D can typically be charged with an Attempt on P1 and the resulting crime to P2 (via transferred intent).
Defenses and mitigating circumstances may also be transferred.
Merger Doctrine
two crimes merge prohibiting D from being prosecuted separately for each.
(1) Inchoate offense and its completed substantive offense. (Solicitation and Attempt but NOT Conspiracy)
or
(2) An offense and its lesser included offense (i.e. Felony Murder during a Robbery precludes being charged with Robbery)
Accomplice Liability
An accomplice is liable for the crimes he committed or counseled and any other probable or foreseeable crimes committed.
To be liable as an accomplice one must:
(1) Aid, counsel, or encourage the principal before or during the commission of the crime
(2a) With the intent to assist the principal; and
(2b) With the intent that the principal commit the crime
Accomplice Liability Defenses/Exceptions
Accomplice liability does not apply where:
(1) Accomplice withdraws before the principal commits IF the accomplice:
(a) repudiates prior aid/encouragement,
(b) do everything possible to counteract prior aid/encouragement and,
(c) do so BEFORE the chain or events is in motion and unstoppable.
(2) Accomplice is a member of a protected class (i.e. minor victim of a statutory rape)
(3) Accomplice is a party not provided for in statute (i.e. purchaser of drugs)
Accessory after the fact
Different than accomplice liability because it relates to actions taken after the commission of the crime (i.e. assisting in escape of known felon).
Gives rise to the crime of obstruction of justice.
Solicitation
Inciting, urging, or otherwise asking another to commit a crime with the intent that they commit it.
Completed once D asks the solicited to commit the felony. No affirmative response is required, but if they agree it becomes a conspiracy.
Refusal is not a defense.
Impossibility/Withdrawal are not defenses.
MPC allows renunciation but Common Law does not (majority).
Conspiracy (elements)
an agreement between two or more people to commit a crime or unlawful objective.
Elements:
(1) agreement between two or more people (i.e. meeting of the minds)
(2) Intent to enter into agreement
(3) Intent to commit the crime
(4) An overt act in furtherance of the target crime***
Note:
Common Law requires both parties to have criminal intent but MPC allows unilateral for cases re: undercover officers.
Conspiracy ends upon completion of the target crime.
Co-Conspirator Liability
each conspirator is liable for co-conspirators’ crimes that are:
(1) Foreseeable; and
(2) Committed in furtherance of the conspiracy
Withdrawal from Conspiracy
Under Common Law, one cannot withdraw from the conspiracy itself but MPC allows withdrawal if the withdrawing party thwarts the conspiracy.
Elements:
(1) Subsequent crimes can be withdrawn from including the target offense of the conspiracy.
(2) An affirmative act that notifies co-conspirators of withdrawal is required.
(3) Withdrawal must be timely (i.e. given enough time for co-conspirators to abandon plans).
(4) The withdrawing party must attempt to neutralize the effect of any assistance he provided to the original conspiracy.
Attempt
An act done with the specific intent to commit a crime, that constitutes an overt or substantial step towards committing the crime, but falls short of completion.
The overt act must be beyond mere preparation. (Dangerously close to success under common law)
Defenses:
(1) Legal impossibility (NOT Factual Impossibility)
(2) Abandonment is NOT a defense.
Insanity
Legal insanity is a defense to all crimes regardless of their level of intent requirement. There are four legal insanity tests: M’Naghten, Irresistible Impulse, MPC, and Durham.
M’Naghten Insanity Test
Due to a mental illness or defect, D does not know right from wrong at the time of the act.
Irresistible Impulse Test
Due to a mental illness or defect, D was unable to control his actions or conform his conduct to the law
MPC Insanity Test
As a result of D’s mental disease, D lacked the capacity to either appreciate the criminality of his conduct or conform it to the requirements of the law.
Durham Insanity Test
but for his mental illness, D would not have acted
Infancy Defense
Minors under 7 years of age have no criminal liability.
Minors aged 7 to 14 have the rebuttable presumption against criminal liability.
Diminished Capacity Defense
If D can show that he has some mental defect short of insanity that prevented him from forming the intent required for the crime. (typically only limits specific intent)
Due Process & D’s mental condition (at trial)
Due Process forbids D from being tried, convicted, or sentenced as a result of mental disease if D is unable to either:
(1) understand the nature of the proceeding, or
(2) assist his lawyers in preparation of his defense.
