"The Hurriyat Conference strongly denounces the proposed Police Bill. It is repressive in nature," an amalgam spokesman said in a statement here.
"We ask the people to oppose it as it aims to destroy the very fabric of a civilised society," he said.
The Jammu and Kashmir Liberation Front (JKLF), another separatist outfit, also condemned the proposed bill.
"Through this bill, the NC-led coalition government wants to give state protection to misdeeds of police and other security agencies and increase their powers," a JKLF statement said.
