10. Offences against public morals and public order

Bigamy, blasphemy, sexual morality and the Public Order Act

Posted By lanbuk.com

In simple terms

This group of offences protects shared moral standards and public peace. Several raise sharp questions in Sierra Leone because of legal pluralism and the constitutional protection of free expression.

Bigamy

Section 57 of the 1861 Act: Being married, marrying another during the life of the spouse.

Proof: The prosecution must prove the first marriage, its validity, that it subsisted, and the second ceremony. A polygamous or potentially polygamous first marriage will not ground bigamy.

Mens rea: An honest and reasonable belief that the first spouse is dead, or the first marriage dissolved or void, is a defence.

Legal pluralism: A man married under customary law may not later marry another woman under the Christian or Civil Marriage Acts; but a man married under those Acts may, under customary law, take further customary wives, though the general law regards those unions as invalid.

Blasphemy and sexual morality

Blasphemy: Historically a common law misdemeanour; the gist is scurrilous vilification of the Christian religion. It is rarely if ever prosecuted today.

Other offences: Incest, brothel-keeping, living on immoral earnings and unnatural offences under the received law.

The Public Order Act 1965

Insulting conduct: Section 3 punishes threatening, abusive or insulting words or behaviour with intent to provoke a breach of the peace. In Dumbar v The State the Court of Appeal, following Ward v Holman, upheld a of a politician who insulted the Prime Minister's government at a public meeting.

Offensive weapons, processions and meetings: The Act also controls these.

Seditious and defamatory libel

History: Part V of the Act created libel, false news and seditious libel. Regina v Loshak convicted a foreign journalist of seditious publication; Conteh v R allowed an appeal where the words did not defame the Prime Minister.

Current law: Part V was repealed by the Public Order (Amendment) Act 2020. Criminal and seditious libel under the Act no longer exist. Loshak and Conteh are now of historical and constitutional interest.

Words and Latin in this note

Mens rea
The mental element in the definition of a crime. It is not one standard. Intention is the highest form. Recklessness is below it. Gross negligence sits at the bottom. The definition of the particular crime decides which is required. Open the note.
