Quick questions on Meaning of crime and the elements of a crime: HSC Legal Studies

A crime is an act or omission against the community that is punishable by the state under the criminal law. It is distinct from a civil wrong (tort, breach of contract), which is between two private parties and resolved by damages or another civil remedy.

The prosecution must prove two elements to convict.

A crime is an offence against the whole community, prosecuted by the state, and punished to protect society; a successful prosecution results in a criminal sanction such as imprisonment or a fine. A civil wrong (such as a tort or breach of contract) is a dispute between private parties, brought by the wronged party, and resolved by a remedy such as damages or an injunction. The standard of proof differs: beyond reasonable doubt for crime, the balance of probabilities for civil matters. The same conduct can give rise to both: a fatal assault can lead to a criminal prosecution for manslaughter and a civil claim in negligence by the family.

Some statutory offences displace mens rea and are strict liability. Common examples include traffic offences (e.g. exceeding the speed limit under the Road Transport Act 2013 (NSW)) and certain regulatory offences. The prosecution need only prove the actus reus.

The physical element. Conduct (an act or omission), circumstances (the surrounding context) and consequences (any result). Murder under the Crimes Act 1900 (NSW) s 18 requires an act causing death.

The mental element. The accused must have acted with the relevant fault state: intention, knowledge, recklessness, or (rarely) negligence. The required mens rea differs offence by offence.
