Definitions and Concepts

Criminal law is a system of rules established by a governing authority to define unacceptable behavior.
These rules are enforced through the state apparatus.
Criminal law distinguishes between criminal and civil wrongs.
A criminal wrong is an act that violates the rights of society as a whole, while a civil wrong affects the rights of individuals.
The goal of criminal law is to punish offenders, deter future criminal behavior, and rehabilitate offenders.
The key functions of criminal law include retribution, deterrence, incapacitation, and rehabilitation.

Elements of a Crime

A criminal act, often referred to as actus reus , is a violation of the law. It encompasses the physical elements of a crime.
A criminal state of mind or mens rea is the mental element necessary for criminal responsibility.
This is a crucial element, and often describes different levels of intent and awareness.
A crime requires a specific outcome or consequence.
This often includes causing harm to another person or property.
Some crimes only require a mens rea without a demonstrable actus reus, while others require both.

Types of Crimes

Crimes can be categorized in different ways, including by severity and nature of the crime.
Felonies are serious crimes, punishable by imprisonment for a year or more.
Misdemeanors are less serious crimes, punishable by a fine or imprisonment for less than a year.
Infractions are the least serious crimes that are usually punishable only by fines.
Crimes are also categorized by the conduct they relate to (e.g.: assault, theft, drug offences).

Defenses to Criminal Charges

A defendant can raise various defenses to a criminal charge, including:
Self-defense
Duress
Necessity
Intoxication
Insanity
Lack of capacity to understand the nature of the act
Entrapment

Procedure in Criminal Cases

Criminal proceedings typically involve arrest, investigation, indictments, arraignments, plea bargaining, trial, sentencing and appeal.
Due process rights are fundamental to protections in the criminal justice system.
These rights vary based on jurisdiction, but most include the right to a fair trial, representation by legal counsel, and protection against self-incrimination.

Punishment and Sentencing

Punishments for criminal offences vary considerably.
They may include fines, imprisonment, community service, probation, or a combination of these.
Sentencing is governed by sentencing guidelines or laws unique to each jurisdiction.
Factors that affect sentencing decisions often include the severity of the crime, the defendant's prior criminal record, and the circumstances of the case.

International Criminal Law

International criminal law governs crimes that affect or concern multiple countries or world stability.
Examples include genocide, war crimes, crimes against humanity, and aggression.
International criminal tribunals and courts are established to address these crimes.
The focus of criminal law is not limited to the national level.
