Crime and Criminal Law
Criminal law, a.k.a. substantive law, is the
law of crimes
Defined by statute
 prescriptions
 proscriptions
Enforced by the state
Primary purpose is to protect the public from
harm by punishing harmful acts that have
occurred and seeking to avoid harm by
forbidding conduct that may lead to it
Crime and Criminal Law
What Is Crime?

Crime and Criminal Law
Crime as a Subset of Harmful Acts
Core offenses
All social harm
Mala in se
Not regulated by
criminal law
All crimes
Mala in se and mala prohibita
All harms
Crime and Criminal Law
Mala in se: Crimes that are considered bad in
of themselves
Mala Prohibita: Crimes that are considered
crimes because we have placed restrictions on
them
Crime and Criminal Law
Sources of Criminal Law
State and federal constitutions
State and federal statutes
Common law

codified in most states mid-1800s
Federal law is growing source of criminal law
Statutes define elements (various parts) of a
crime more specifically than common law
Crime and Criminal Law
Limitations on the Criminal Law
Substantive due process: There are limits to
what conduct the law may seek to prohibit
Forbids passage of laws that infringe on the
rights of individuals


free speech
assembly
Overbreadth doctrine: Laws are
unconstitutional when they fail to narrowly
define the specific behavior to be restricted
Crime and Criminal Law
Limitations on the Criminal Law (cont.)
Void for vagueness: laws are unconstitutional
if they fail to clearly define the prohibited act
and the punishment in advance
Fair notice: letting people know what is and is
not permitted
Must not restrict due process: laws must be
enforced fairly and non-arbitrarily
Must not restrict equal protection: laws
cannot restrict the rights of members of
suspect classifications
Crime and Criminal Law
Limitations on the Criminal Law (cont.)
Cruel and unusual punishment: punishments
must be proportional to the crime
Ex post facto laws: people cannot be
penalized for behavior which was not illegal
at the time they acted; penalties cannot be
increased after the crime has been committed

ex post facto laws do apply retroactively if they
are beneficial
Bills of attainder: laws that impose
punishment without trial
Crime and Criminal Law
Elements of Criminal Offenses
Elements must be present for criminal liability
to attach
Actus reus
Mens rea
Concurrence
Causation
Harm
Make up the corpus delicti
Crime and Criminal Law
Actus Reus (Criminal Act)
The guilty act; three forms:
Voluntary bodily movements
An omission in the face of a duty to act


failure to perform a legal duty
failure to prevent serious harm when a special
relationship exists
Possession

if the person has some knowledge that their
possession is illegal
Crime and Criminal Law
Mens Rea (Criminal Intent)
Guilty mind; inferred from circumstances
surrounding the criminal act
Four levels:
1. Purposeful
2. Knowing
3. Reckless
4. Negligent
Doctrine of transferred intent
Crime and Criminal Law
Concurrence
The union of the criminal act and the criminal
intent (actus reus and mens rea)
Crime and Criminal Law
Causation
The criminal act is the act that is the cause of
the harm
2 types:
1. Factual cause: “but for” the actor’s
conduct the harm would not have occurred
2. Legal cause: consequences of an act
which are not reasonably foreseeable to the
actor (intervening causes) relieve the actor of
some degree of criminal liability
Crime and Criminal Law
Harm
The result of the act, the injury to another or
to society
Crime and Criminal Law
Liability Without Fault
Strict liability: imposes accountability without
proof of criminal intent in situations where
society deems it fair to do so
Statutory rape
Vicarious liability (only civil law) : the
imputation of accountability from one person
to another
Crime and Criminal Law
Inchoate Crimes
Crimes that occur in preparation for an
offense
Three types:



attempt
solicitation
conspiracy
Crime and Criminal Law
Parties to Crime
Doctrine of complicity—where more than one
person may be held liable for criminal activity
Requires that all criminal elements be present
Common law recognizes four parties to a
crime:
1. Principles in the first degree
2. Principles in the second degree
3. Accessories before the fact
4. Accessories after the fact
Crime and Criminal Law
Defenses to Criminal Liability
Defense is a response by the defendant
which allows them to avoid criminal liability
Alibi: defendant asserts that they did not
commit the crime
Affirmative defenses: defendant admits that
they committed the act, but deny criminal
liability
Shifts both the burden of production and
persuasion to the defense (preponderance of
the evidence)
Crime and Criminal Law
Justification Defenses
A defense in which the defendant admits they
are responsible for the act, but claims that
under the circumstances the act was not
criminal
Self-defense
Consent
Execution of public duties
Crime and Criminal Law
Self-Defense
Use of force to repel an imminent, unprovoked
attack, in which they reasonably believed that
they were about to be seriously injured
May only use as much force as is necessary
Retreat doctrine: a person must retreat rather
than use deadly force if doing so is possible
Castle doctrine: persons attacked in their home
need not retreat
Can also apply to the defense of others and
property
Crime and Criminal Law
Consent
Persons may content to suffer what otherwise
would be an objectionable injury
Consent must be voluntary, knowing, and
intelligent
Crime and Criminal Law
Execution of Public Duties
Agents of the state are permitted to use
reasonable force in the lawful execution of
their duties
Crime and Criminal Law
Excuse Defenses
One in which the defendant admits that what
they did was wrong but that under the
circumstances they are not responsible for
their improper conduct




duress
intoxication
age
insanity
Crime and Criminal Law
Duress
Situations involving the threat of serious,
imminent harm to oneself, where the act is
less serious than the threatened harm
Those forced to commit a crime in such
circumstances do not act voluntarily


eliminates actus reus
eliminates mens rea
Crime and Criminal Law
Intoxication
Voluntary and Involuntary
Voluntary never leads to acquittal; may only
mitigate
Involuntary may work as a defense as the
person is not responsible for their actions
Crime and Criminal Law
Age
Persons below a certain age lack the
capability to form mens rea
Crime and Criminal Law
Insanity
Impairs mens rea
Mental illness and legal insanity are not the
same
M’Naghten rule—right wrong rule
Durham test—product test
Irresistible mpulse test
Substantial capacity test
GBMI- from Insanity Defense Reform Act of
1984
Crime and Criminal Law
Procedural Defenses
It is claimed that the defendant’s due process
rights were violated
Double jeopardy, denial of speedy trial, use of
illegally seized evidence
Entrapment in one of two scenarios (Sherman v.
U.S. 1958)
1. The crime is the result of the “creative
activity” of law enforcement
2. The prosecutor cannot prove beyond a
reasonable doubt that the defendant was
“independently predisposed” to commit the crime
