In simple terms
Two years after independence Sierra Leone replaced the inherited English law of treason with its own statute, the Treason and State Offences Act 1963. Its leading interpretation comes from the case that followed the 1967 military takeover.
The 1963 Act
Treason (s.3): Preparing or endeavouring to overthrow the Government by unlawful means; preparing or endeavouring to carry out by force an enterprise which usurps the executive power of the State; inciting or assisting an armed invasion; and assisting an enemy in time of war.
Treason felony (s.4): Lesser acts such as preparing or endeavouring to procure an alteration of the law by unlawful means.
Inchoate treason: Attempts, soliciting and incitement are covered.
Attorney-General's consent: Section 1(2) requires the Attorney-General's consent before a prosecution is instituted.
Lansana and Eleven Others v Reginam
Separate offences: "Prepares" and "endeavours" in s.3(1)(a) create two separate offences, so a count charging both is bad for duplicity.
Consent: Consent is a condition ; without valid consent, given with knowledge of the facts and before the matter first comes before a magistrate, the proceedings are a nullity.
Conspiracy as an overt act: A conspiracy to do the forbidden acts is an overt act of "preparing" under ss.3 and 4.
Later cases: Lansana was applied in Juxon-Smith v The State and in the treason trials of State v Jemilah Bangura and State v Mohamed Forna and Fourteen Others.
Sedition
Akin to treason: Sedition was sometimes described as akin to treason, but Sierra Leone repealed seditious in 2020.
Current law note
Penalty: Treason now carries life imprisonment, not death.
