The Western Australian Government's stop and search legislation will not pass through parliament this year.

The bill would give police the power to search people for weapons in entertainment precincts without proving grounds for suspicion.

The Police Minister Rob Johnson says he is referring the legislation to an upper house committee for review.

Mr Johnson admits pressure from his Liberal colleagues persuaded him to consider a last-minute compromise on his stop and search legislation.

"I'm not too upset that it'll take an extra couple of months or so to get this legislation into law," he said.

Mr Johnson says it had become clear Labor would filibuster during debate and conceded some of his colleagues had raised concerns about the lack of parliamentary scrutiny of the legislation.

The Minister says he will consider any amendments suggested by the committee.

Today is the last scheduled parliamentary sitting day of the year.

'Embarrassing setback'

The State Opposition says the government's admission that its stop and search legislation will not pass parliament this year is an embarrassing setback for Mr Johnson.

Labor's Leader in the Upper House Sue Ellery says the minister has buckled to criticism of the laws from the public and his own backbenchers.

"Rob Johnson is a joke and Rob Johnson has demonstrated that yet again and tried to cover his own tracks by blaming the Labor Party for delaying a debate the government hasn't even started," she said.
