The Callinan review into lockout laws, which was due to be released by the end of August, has been delayed until mid-September.

The NSW Government will now receive the independent review on 13 September following an extension request by the Hon. Ian Callinan AC, according the Liquor and Gaming NSW.

Callinan made the formal request this week on the back of the State Supreme Court’s ruling that the NSW Justice Department does not have the legal authority to declare Sydney specific CBD venues subject to the lockout laws.

The retired Justice of the High Court of Australia is awaiting further evidence and examining the recent Supreme Court decision regarding the lockouts.

Mr Callinan was appointed to review the effectiveness of the 1.30am lock outs, 3am cut-off for liquor sales, 10pm take-away liquor laws and the annual liquor licence fee program.

Callinan has received more than 1,800 public submissions and input from three round-tables. There have been calls to lift blanket lockout laws, while Sydney Lord Mayor Clover Moore called for compromise.
