actus reus

The physical element of a crime: the conduct, act, or legally relevant omission that the prosecution must prove, together with its circumstances and consequences, beyond reasonable doubt.

Related: mens rea, burden of proof, strict liability offence
mens rea

The mental element of a crime, such as intention, recklessness, or negligence. Except for strict liability offences, the prosecution must prove the accused held the required state of mind.

Related: actus reus, strict liability offence, criminal negligence
strict liability offence

An offence where the prosecution need not prove mens rea; proof of the prohibited act alone suffices. Common for traffic and regulatory matters, though defences of honest and reasonable mistake may apply.

Related: mens rea, actus reus, summary offence
burden of proof

The obligation on a party to prove a fact in dispute. In criminal trials the prosecution bears this burden and must satisfy the criminal standard of proof.

Related: standard of proof, presumption of innocence, actus reus
standard of proof

The degree of certainty required to discharge the burden of proof. Criminal guilt must be established beyond reasonable doubt; civil liability is decided on the balance of probabilities.

Related: burden of proof, presumption of innocence
presumption of innocence

The principle that an accused person is treated as innocent until the prosecution proves guilt. It underpins bail considerations, trial procedure, and the right to silence.

Related: burden of proof, right to silence, bail
summary offence

A less serious criminal matter heard by a magistrate alone in the Local Court, without a jury, and carrying limited maximum penalties such as imprisonment of up to two years.

Related: indictable offence, committal hearing, strict liability offence
indictable offence

A serious criminal matter ordinarily tried on indictment before a judge and jury in the District or Supreme Court, attracting heavier maximum penalties than summary offences.

Related: summary offence, committal hearing, charge negotiation
committal hearing

A Local Court proceeding in which a magistrate decides whether the prosecution evidence is sufficient for a serious matter to proceed to trial in a higher court.

Related: indictable offence, summary offence, legal aid
charge negotiation

Also called plea bargaining: an arrangement where the accused agrees to plead guilty, often to a reduced charge or with fewer counts, in exchange for a lighter outcome.

Related: indictable offence, mandatory sentencing, sentencing discretion
legal aid

Government-funded legal assistance for people who cannot afford representation, subject to means and merit tests. Access is limited and many accused remain unrepresented.

Related: committal hearing, presumption of innocence, court hierarchy
bail

The conditional release of an accused person into the community while awaiting trial or sentence. Australian law now emphasises unacceptable risk and, for some offences, a show cause requirement.

Related: remand, presumption of innocence, crime prevention
remand

Detention in custody of an accused person who has been refused bail or cannot meet bail conditions, pending trial or sentencing. Remandees are legally presumed innocent.

Related: bail, presumption of innocence, recidivism
court hierarchy

The ranking of courts from Local Court through District and Supreme Courts to appellate courts. It allocates jurisdiction, enables appeals, and produces precedent.

statute law

Legislation enacted by parliament, such as the Crimes Act 1900 (NSW). It is the dominant source of criminal law and can override inconsistent common law rules.

Related: statute law, precedent, defence of mental illness
defence of mental illness

A partial or complete answer to a charge where the accused's mental impairment prevented them from knowing the nature or wrongness of the act. May lead to detention in a mental health facility.

Related: mens rea, common law, criminal negligence
criminal negligence

A failure to exercise the standard of care a reasonable person would exercise, so serious and blameworthy that it warrants criminal liability, as in dangerous driving causing death.

Related: mens rea, defence of mental illness, actus reus
sentencing discretion

The latitude a judicial officer has to select a penalty after weighing aggravating and mitigating factors, guided by statutory purposes such as deterrence, rehabilitation, and protection of the community.

Related: mandatory sentencing, recidivism, charge negotiation
mandatory sentencing

Laws that fix a minimum penalty for particular offences, removing or limiting judicial discretion. Critics argue such laws can produce unjust outcomes and breach proportionality.

Related: sentencing discretion, rule of law, recidivism
recidivism

Reoffending by a person previously convicted or punished. High rates are used to evaluate whether sentencing achieves rehabilitation and community protection.

Related: sentencing discretion, remand, crime prevention
crime prevention

Related: recidivism, young offenders, bail
