Jakarta. Deliberations to revise the existing antiterrorism law may not be finished within this year, a lawmaker has said amid mounting calls for immediate enactment of the government-proposed bill.

Seeking tougher action against alleged terrorists, the revised law was scheduled for enactment in October — nine months after the revisions were proposed.

Lawmakers had asked security experts, human rights activists, Islamic scholars and state officials to give their input on the revised law by August, but the request had fallen on deaf ears so far.

"They will submit their input to the special committee in late October instead," Arsul Sani, a member of the House of Representatives' special committee for the antiterrorism bill, said on Thursday (25/08).

The government-proposed revisions range from preventive detention aimed at deradicalization, longer period of arrest, revocation of citizenship, wiretapping without court permit to the involvement of the Indonesian military in counterterrorism operations.

"The revisions have sparked controversies. We don't want to rush this bill," Arsul, a United Development Party lawmaker, said.

"The special committee's deliberations may not be completed until late this year," he said.

The government proposed the revisions to the existing law on antiterrorism in January, when the country was on heightened alert following attacks by Islamic State sympathizers in downtown Jakarta, killing eight people.

Calls for immediate enactment of the bill reemerged last month when an Islamic State-linked suicide bomber attacked the Solo Police headquarters in Central Java, killing himself and injuring an officer.
