Criminal Law Flashcards
Elements of a Crime
1) Act -voluntary act (willed bodily movement) -omission/failure to act
2) Causation
3) Mental State (mens era) i.e. intent
**General Rule: almost every crime requires the 3 elements. DON’T DISCUSS MENTAL STATE if the other elements aren’t met.
Burden of Proof for Criminal Cases
Beyond a Reasonable Doubt is required (except for petty offenses) (preponderance of evidence standard violates due process clause)
Other Burdens of Proof in Criminal Cases
1) Burden of Production - coming forward with enough evidence to put a fact at issue 2) Burden of Persuasion - convincing trier of fact (usually jury) that the evidence proves a fact if D has burden of production for an issue, the issue is called “affirmative defense” (i.e. insanity)
Right to Trial by Jury
only petty offenses can be tried by a judge. 6th Amendment guarantees right to trial by jury. greater than 6 months in jail = right to jury trial
What is a petty offense?
Less than 6 months in jail. More than 6 months in jail=right to jury trial
Theories of Punishment
+Retribution - (backward looking)
+Utilitarianism
+Deterrence - (forward looking)
- specific: offender afraid to re-offend
- general: send message to society in general. everyone afraid to offend.
+Rehabilitation - (“fix” the offender for his/her own good & good of society)
Moral Influence Theory
+Incapacitation - (‘thug in prison can’t shoot your sister’)
Omissions
General Rule: omission is not an act Exception: where you have a duty to act. duty exists in limited circumstances. MPC 2.01: must be physically capable AND have a legal duty.
Omissions: 4 situations where failure to act may be breach of legal duty
1) statutory 2) status relationship (i.e. mother/child, spouses) 3) contractual 4) omission AFTER: creation of risk OR assumption of care
Omission Recap
omission is NOT an act UNLESS physically capable of acting AND duty exists. Duty exists IF: statutory, status relationship, contractual, or omission after creation of risk or assumption of care
Acting
Cause (stimulus) & Effect: Stimulus (cause): axe, poison, throw a punch, throw a can of gasoline Effect: death, vomiting, burns down building
Causation
Actual Cause (“but for” causation) Proximate Cause (was effect foreseeable)
Causation
Step 1 (stimulus): Ask “but for”…i.e. “but for Colonel Mustard swing the axe, would victim have died?” Step 2: Ask “was the effect of the stimulus foreseeable?”
Proximate Cause Test
Needs to be foreseeable and should not be highly extraordinary
Actual Causation: Special Rules
+accelerating the result if my actual cause accelerates a result that would have otherwise occurred, then both are actual causes. Dealing with multiple actual causes simultaneously. Tiebreaker.
+concurrent sufficient causes two people attack simultaneously, then both are actual causes. “but for” test does not work.
+independent supervening cause examples: but for the stabbing, would John have died from cancer?
Proximate Causation: Special Rules
- Special Rule on Foreseeability
- Eggshell Skull Rule
- you take your victim as you find them
- if reasonable person in your situation would have known this person has thin skull,then you are proximate cause of death of thin skulled person
- Medical Malpractice
- “mere” malpractice is foreseeable (may still be proximate cause)
- “gross” malpractice is not foreseeable (not proximate cause)
- Eggshell Skull Rule
Causation Flowchart
- Determine if action is “but for” cause (actual causation)
- Determine if action is “foreseeable” or instead “highly extraordinary” (Proximate causation). Foreseeable, proximate cause. Highly extraordinary, then not proximate cause.
- Before you make conclusion that someone was actual or proximate cause. Ask if there is a human actor whose act comes between 1st act and the effect. i.e. did someone else’s act intervene between first person’s act & final result.
- Ask if middle actor’s act is “voluntary”. (Volunary = “free, deliberate, informed”)
- IF YES for #3 & #4, then this middle act is “intervening cause” or “superceding cause” and original actor is no longer the legal cause
Voluntary has different meanings for the act and causation
Act: Voluntary act = willed bodily movement
Causation: voluntary = free, deliverate, informed behavior. involuntary if middle actor acts because of: shame (stephenson); public duty; fear; insanity; ignorance of fact; self-defense. Involuntary=not intervening cause. Typically a year and a day rule applies for causation.
intentionally, knowingly, willfully…all mean the same thing
negligence: inadvertant risktaking, gross deviation from reasonable person
recklessness: early common law, same as negligence
malice: intent or recklessness
MPC Mental States
Purposely, knowingly, recklessly, negligently
MPC vs C/L Mental States
Purposely (C/L: Intent)
Knowingly (C/L: intent)
Recklessly (Old C/L: Negligence)
Negligently (C/L: Negligence)
(from Regina v Cunningham)
Purposely: conscious object to engage in conduct or cause result
Knowingly: awareness/practically certain
Recklessly: conscious disregard of substantial and unjustified risk
Negligently: disregard of…risk of which he should have been aware
Knowledge is satisfied if D is aware of high probability of existence of fact, unless he actually believes it does not exist
MPC Principles of Interpretation for Mens Rea
1) single mens rea term applies to every element that follows the mens rea (unless a contrary purpose is clear)
2) if statute is silent, must show recklessness (at a minimum)
Strict Liability Crimes
Presumption against strict liability
factors considered to overcome presumption:
- public welfare offense?
- legislative policy?
- reasonable burden?
