Section 25

Any postal article sent by post which is suspected by the

Postmaster General to be sent in contravention of any of the provisions of this Act or of any rule made thereunder may be detained and opened in the post office in the presence of the Postmaster General and shall either be returned to the sender or forwarded to its destination, in each case charged with such additional postage (if any) as the Minister with the approval of His

Majesty the Sultan and Yang Di-Pertuan prescribes unless otherwise dealt with under sections 26, 28, 29, 30 and 31.

Any officer in charge of a post office or authorised by the

Postmaster General in that behalf may open or unfasten any printed packet, literature for the blind, or small packet, in course of transmission by post, with a view to detect any attempt to contravene the provisions of this Act or of any rule made thereunder.

If any question arises whether any postal article is a letter or any other description of postal article within the meaning of this Act, the decision thereon of the Postmaster General shall be final and shall not be subject to appeal to or review in any court.
