s 31 Authorisation for enforcement officers
31.—(1) The Authority must issue to each enforcement officer a written authorisation specifying such of the powers expressly specified in section 22, 23 or 24 as exercisable by an enforcement officer, as what that enforcement officer may exercise, and no other powers. (2) The authorisation under subsection (1) issued to an enforcement officer may also do all or any of the following:(a) limit when, and where in Singapore, the enforcement officer may exercise powers in section 22, 23 or 24 expressed as exercisable by an enforcement officer or any of them; (b) limit the circumstances in which the enforcement officer may exercise those powers or any of them. (3) To avoid doubt, the Authority cannot authorise under this section an enforcement officer to arrest any individual. (4) The powers that an enforcement officer may be authorised under this section to exercise may be exercised only —(a) to the extent authorised by the Authority under subsection (1); (b) upon production of the identification card issued under section 30(3); and (c) as directed (generally or specially) by an authorised officer or other employee of the Authority. (5) An enforcement officer who is authorised under subsection (1) to exercise any power expressly specified in this Act as exercisable by an enforcement officer is deemed to be a public servant for the purposes of the Penal Code 1871 when exercising that power. (6) To avoid doubt, an enforcement officer does not cease to be acting on the direction of an officer or employee of the Authority by reason only that the officer or employee of the Authority is not present at all times.
