What is CL and MPC broadly?

Common law is judge made rules in preceding case law that can be used when non statute exists or the statute is unclear.

Model Penal Code is when states adopt parts or all of the MPC to create clearer statutes.

200

Intoxication CL v. MPC

  • Intoxication acts as a defense to crime if it negates a required element of the crime

  • At Common Law, voluntary intoxication is only a defense to the extent that it negates the mens rea of a specific intent crime (i.e., voluntary intoxication cannot serve to negate the mens rea for a general intent offense. You don’t get a pass for being drunk if you made yourself that way!) As such, it is a failure-of-proof defense

  • Under the M.P.C., a defendant may not introduce evidence of intoxication to negate a reckless (or negligent) mens rea

  • Both the Common Law and M.P.C. recognize involuntary intoxication as an affirmative defense 

200

Types of Omission Crimes

  • 1) State imposes a duty to act

  • 2) Relationship imposes a duty to act

  • 3) Contractual duty to care

  • 4) Voluntary assumption of care

  • 5) Creation of the peril

200

CL Involuntary Manslaughter Rule

In the commission of an unlawful act that is not a felony: (1) high degree or risk of death or serious bodily injury, in addition to the unreasonable risk required for ordinary negligence and (2) The defendant must be aware of the fact that his conduct creates that risk 

(Gross negligence so extreme that is punishable as a crime)

200

300

Solicitation CL v. MPC Key Differences

  • Failure to communicate is no bar to convocation under the MPC (even if letter has not actually been received) but is a bar in common law

  • Abandonment available under the MPC (BUT, must persuade or prevent; as with all abandonment, must be complete and voluntary)

300

CL Necessity Defense Rule

The defendant (1) reasonably believed that there was (2) an actual and specific threat that (3) required immediate action; (4) there was no realistic alternative to the criminal act, (5) the harm caused was not greater than the harm avoided, and (6) defendant did not contribute to/cause the threat

300
CL Depraved Heart Murder

Extremely reckless conduct, which creates what a reasonable man would realize to be not only an unjustifiable but also a very high degree of risk of death or serious bodily injury to another or to others - though unaccompanied by any intent to kill or do serious bodily injury – and which actually causes the death of another, may constitute murder

Note***

Below knowledge but above recklessness so with some knowledge (if it is just recklessness it is just involuntary manslaughter)

300

Accomplice Liability MPC

  • A person is an accomplice of another person in the commission of an offense if:

    • a) with the purpose of promoting or facilitating the commission of the offense, he

      • i) solicits such other person to commit it, or

      • ii) aids or agrees or attempts to aid such other person in planning or committing, or

  • Common Law: look to what remains to complete the offense, based on the gravity of the offense and probability of success

  • MPC: look to what has been done already

400

    • An intentional homicide committed by a defendant who, when he killed the defendant, was in the heat of passion from adequate provocation from the victim, which a reasonable man would lose his self-control from.

Conspiracy CL v. MPC

  • Common Law

    • Must be bilateral (at least 2 people agree)

    • Overt act not traditionally required but now a statutory requirement

    • Conspiracy merges into completed offense

    • Pinkerton Rule: A co-conspirator can be convicted of substantive offenses committed by a co-conspirator so long as it was reasonably foreseeable that the substantive offense was within the scope of the unlawful project (in this case he was sitting in jail when the offenses)

  • MPC

    • Permits unilateral conspiracy (can form even where only one party agrees)

    • Overt act “in pursuance of” the conspiracy required (except for most serious offenses which I do not need to memorize)

    • No merger! Parities may be convicted of conspiracy and completed offenses

    • No Pinkerton liability: parties only liable for conspiracy and crimes they have personally committed

500
Vicarious Liability of Co-Conspirators: the Pinkerton Rule

A defendant can be held vicariously liable for a substantive offense committed by another member of a conspiracy if: (1) the defendant was a party to the conspiracy, (2) the offense was within the scope of the unlawful project, (3) the offense was committed in furtherance of the conspiracy, and (4) the defendant could have reasonable foreseen the offense as a necessary or natural consequence of the unlawful agreement

The M'Naghten Test Rule Statement
