A review of laws designed to crack down on misbehaving pubs and clubs is being kept under wraps by the NSW government, despite Parliament being asked to consider significant changes and an extract being provided to a Sydney hotel baron.

A bill introduced by Racing Minister Paul Toole winds back key aspects of the "three strikes" law under which pubs face the loss of their licence for serious breaches under the Liquor Act. For clubs, the ultimate penalty is the removal of a licensee.

The changes before Parliament include removing the automatic nature of a first strike for a breach as well as reducing the types of breaches attracting a strike.

As well, while presently a strike remains in place for three years, the bill allows a venue's licensee to appeal to the Independent Liquor and Gaming Authority after six months to have it removed for good behaviour.
