Comprehensive practice flashcards covering the elements of crime, categories of crime, parties to a crime, offence classifications, and crime prevention strategies from the lecture notes.

Define the meaning of crime

A crime is any act or omission of duty (failure to act) that results in harm to society by the state.

Why does the concept of what is considered a crime change over time?

Crime is linked to moral and ethical judgements about a person's behaviour, meaning it changes alongside society's attitudes (for example, regarding homosexuality or euthanasia).

What three key elements must the Crown prove to secure a criminal conviction?

1. Actus Reus (the accused committed the guilty act)
2. Mens Rea (the accused intended to commit the crime / guilty mind)
3. Causation (a link between the act and the crime)

What forms can Actus Reus take, and how can it be proven in court?

It can be a voluntary physical act (e.g., using a weapon to harm someone) or the planning of a crime (e.g., planned terrorism). It is proven by witness testimony, physical evidence, and/or DNA evidence.

Which case is cited as an example relating to Actus Reus?

R v Dean [2013] NSWSC 1027.

What is Mens Rea, and what different levels of intention can satisfy it?

Mens Rea focuses on the mental state of the accused (guilty mind). The requisite levels of intention set by legislation can include wilful, reckless, or criminally negligent intent.

Which case is cited as an example relating to Mens Rea?

R v Thomas Sam; R v Manju Sam (No. 18).

What is a strict liability offence, and why are these offences utilised?

A strict liability offence is an exception where the prosecution only needs to prove the actus reus, without having to prove mens rea. They are often considered resource efficient (e.g., speeding or running a traffic light).

Which case is cited in connection with strict liability offences?

R v Wayne Alfred CARR [2017] NSWLC 21.

What is causation in criminal law, and what must the prosecution establish regarding it?

Causation requires the prosecution to prove a substantial link between the criminal act and the harm caused, meaning the chain of causation (the series of linked events leading to the outcome) must not be broken.

Which case is cited to illustrate causation and the chain of causation?

R v Blaue (1975) WLR.

How does the categorisation and seriousness of a crime affect where it is heard?
