Selangor exco member Nik Nazmi Nik Ahmad's legal troubles for organising the Black 505 rally three years ago is not over, as prosecutors are appealing against the punishment meted last month.

Lawyer Syahredzan Johan confirmed the appeal by the Attorney-General's Chambers.

"We were informed a couple of days after the High Court decision, while the official notice of appeal dated Dec 14 was received yesterday," he said.

The notice of appeal by the chambers was signed by Trials and Appeals division head Ahmad Kamal Md Shahid. With this, the appeal will be heard at the Court of Appeal in Putrajaya.

Nik Nazmi, who is also the Seri Setia assemblyperson, was fined RM1,500 by the Shah Alam High Court on Dec 8 for violating the Peaceful Assembly Act 2012.

The Selangor exco member for education, science and innovation had pleaded guilty to the offence of not giving proper notice on the Black 505 rally held on May 8, 2013 at a stadium in Kelana Jaya.

Under Article 64(1)(e) of the Selangor state constitution, an elected representative can lose his seat if he is jailed for a year or fine of not less than RM2,000 and has not received a pardon.

Nik Nazmi pleaded guilty after three witnesses had testified in the trial which began last month.

On April 25, 2014, the Court of Appeal struck out his charge after it declared the requirement to give the 10 days' notice as unconstitutional.

However, another Court of Appeal bench led by Court of Appeal president Justice Md Raus Sharif ruled in Johor PKR secretary R Yuneswaran's case that giving a 10-day notice was not against the constitution.

Following that Nik Nazmi and several others were re-charged under Section 9(5) of the Peaceful Assembly Act 2012.
