It is competent for a magistrate to impose both a fine and a term of imprisonment (even if wholly suspended) for a single offence, as provided for in section 50(5) of the Magistrates Court Act. What is incompetent is the imposition of two separate terms of imprisonment for one offence. However, where a sentence is manifestly too lenient so as to induce a sense of shock or constitute a mockery of justice, a reviewing court is entitled to withhold its certificate.
