NSW MPs are spending as little as 60 seconds meeting to assess the human rights implications of proposed laws such as police powers and limits to Aboriginal land claims, prompting criticism that Parliament's oversight regime is an "embarrassing" rubber stamp.

Minutes from the government-dominated Legislation Review Committee, set up to determine if bills trespass on personal rights and liberties, show the average fortnightly meeting last year ran for 3.25 minutes, raising questions over whether proposed laws are being properly scrutinised. Two meetings lasted one minute.

Nationals MP Stephen Bromhead says the committee works effectively.

The NSW Greens have called for the committee to be abolished and replaced by a NSW Human Rights Commission and a Human Rights Act to protect civil liberties. Both safeguards exist in Victoria.

But the committee's chair, Nationals MP Stephen Bromhead, says longer meetings are not needed and the committee works effectively.
