For purposes of section 1(1) of the General Law Amendment Act 50 of 1956, 'control' (beheer) requires more than mere physical possession or detention (detentio). It requires complete control, namely physical possession together with lawful authority over the property, including the right or permission to use it or permit its use, either for a specific purpose or at discretion. The nature of the article and the circumstances relating to possession determine whether there is control. A police officer in charge of a vehicle pound who has custody of seized vehicles held as evidence has control only in a limited administrative capacity for the purposes authorized by the Criminal Procedure Act, not complete control. Unauthorized removal and use of such vehicles constitutes removal from the control of the institution that has lawful control, thereby satisfying the elements of the offence under section 1(1).
