Section 33 Exercise of powers
This section applies for the purposes of sections 21 to 30.
A power conferred on a person—
is additional to powers which he has at common law or by virtue of any other enactment, and
shall not be taken to affect those powers or Her Majesty's prerogative.
A constable or member of Her Majesty's forces may if necessary use reasonable force for the purpose of exercising a power conferred on him.
Where anything is seized it may (unless the contrary intention appears) be retained for so long as is necessary in all the circumstances.
A power to search premises conferred by virtue of this Act shall be taken to include power to search a container.
A member of Her Majesty's forces exercising a power when he is not in uniform shall, if requested to do so by a person at or about the time of exercising the power, produce to that person documentary evidence that he is a member of Her Majesty's forces.
