SIS Forum (Malaysia) (“SIS Forum”) sought judicial review of the Minister of Home Affairs’ (“Minister”) decision to ban a book published by it, “Muslim Women and the Challenges of Islamic Extremism”. The book was a compilation of essays submitted during an international roundtable discussing challenges faced by Muslim women, including gender discrimination. The book was in circulation for two years before it was banned by the Minister for violating the Printing Presses and Publications (Control of Undesirable Publications) (No 5) Order 2008 (the “Act”). The Act prohibits publication of materials which are “prejudicial to public order”, among other things, and affords the Minister an absolute discretion to prohibit publication of any material contravening the Act. The High Court found that the Minister was unable to provide examples of how the book implicated public order issues by affecting public safety and tranquility of the community. Moreover, the book had been in circulation for 2 years and had not adversely impacted the safety and tranquility of the public. Accordingly, the High Court granted judicial review application for substantive relief to SIS Forum.
