It is now illegal to wear a Bersih 4 T-shirt after the government this evening officially gazetted them as "undesirable" items.
According to the order issued by Home Minister Ahmad Zahid Hamidi, any yellow clothing which carried the word 'Bersih 4' and any printed material and pamphlet which leads to Bersih 4 are now illegal.
The materials were included into a schedule of prohibited items.
"The printing, importation, production, reproduction, publishing, sale, issue, circulation, distribution or possession of the publication described in the Schedule which is likely to be prejudicial to public order, likely to be prejudicial to security, likely to be contrary to any law and likely to be prejudicial to
national interest are absolutely prohibited throughout Malaysia," read the order.
The executive order was uploaded on the Attorney-General's Chamber's website this evening.
The ban came just a day before the Bersih 4 rally tomorrow which is expected to extend for 34 hours.
"This order may be cited as the Printing Presses and Publications (Control of Undesirable Publications) (NO.22) Order 2015," it read.
The order was made under Section 7(1) of the Printing Presses and Publications Act 1984.
Under Section 7(1) of the law, the minister has absolute discretion by order published in the gazette to prohibit any material deemed prejudicial to public order, morality, security or that that will alarm public opinion.
