The Queensland Council for Civil Liberties (QCCL) says police will be pressured into breaking the law to keep their figures up on scorecards.

As the Queensland Police Service aims to reduce state-wide crime by 10 per cent, officers will be assessed according to their number of traffic fines, random breath tests (RBTs) and street checks.

Terry O'Gorman from QCCL says it is a return to the so-called "kill sheet" quotas of the 1970s and 80s.

He says police will be under pressure to break the law.

"Police under pressure to complete scorecards will cut corners, will bully and bluster people into letting police search their cars when the police have no right to," he said.

"If police are going to be put on scorecards and you've got say 10 police in a squad and four are doing fewer RBTs, fewer street stops than the rest of them, then those four are going to be asked by their superior for a please explain.

"That is a return to the kill sheet."

Mr O'Gorman claims complaints have already been received about the abuse of search powers since the new bikie laws came into effect late last year.

But Queensland Police Commissioner Ian Stewart has defended the scorecard system, saying it is not a repeat of the controversial 1970s and 1980s quota system.

"I expect our people to do their job. Their job is to stop crime in the community, make the community safer and build relationships with our community on a constant and continuous basis," he said.
