Clause 10

A Controller and any authorised officer may detain, open and examine any article coming into Singapore in any manner whatsoever from any place outside Singapore which he has reason to believe contains or consists of a publication the importation, sale or circulation of which is prejudicial to public safety or public interest in Singapore.

If after such article has been opened and examined it is found to contain or to consist of a publication which in the opinion of the Controller or authorised officer is prejudicial to public safety or public interest in Singapore he may detain such article for so long as he deems necessary and may in his absolute discretion destroy or cause to be destroyed such article or such contents thereof consisting of any such publication:Provided that instead of destroying or causing any such article to be destroyed the Controller or authorised officer may in his discretion cause the same to be returned to the sender thereof.

The provisions of this section shall not apply to any article sent from any country outside Singapore and coming into Singapore by land, air or water (whether or not landed or transhipped in Singapore) for the sole purpose of being carried to any country outside Singapore either by the same or another conveyance.
