By seriousness

Treason: The gravest offence, now governed by the Treason and State Offences Act 1963.

Felonies and misdemeanours: The old English division survives in Sierra Leone because the received law still uses it. Felonies were the serious offences; misdemeanours the lesser ones.

Customary offences: Offences known to customary law and tried in local courts.

By mode of trial

Indictable offences: Tried in the High Court on .

Summary offences: Tried by magistrates.

Hybrid offences: Offences triable either way.

By moral quality

Mala in se and mala prohibita: Wrongs in themselves, as against wrongs only because forbidden. Regulatory offences are typically mala prohibita, and are more often strict.

By subject matter

The scheme of this module: Offences against the person, against property, against public morals and order, against the State, and against the administration of justice, followed by inchoate offences and defences.
