Commentary on Sections Powers: supplementary Section 33: Exercise of powers
84.This section provides that powers under sections 21 to 30 are additional to those already in common law, and should not be taken to affect the Royal prerogative. It also provides for the use of reasonable force by a constable or member of the armed forces in relation to those sections.
85.Anything seized may be retained for as long as is necessary and a power to search premises conferred by this Act includes the power to search a container. A member of HM Forces not in uniform must produce evidence that he is a member of HM Forces, if he is requested to do so when exercising the powers in sections 21 to 30.
