Legislation to establish a new supreme court for both New South Wales and Van Diemen's Land was prepared in London by James Stephen, counsel to the Colonial Office, and Francis Forbes, Chief Justice of Newfoundland and Chief Justice-designate of New South Wales. The act was called an "Act to provide for the better administration of justice in New South Wales and Van Diemen's Land and for the more effectual government thereof" and is commonly numbered as "4 Geo. IV, c. 96". The statute was passed on 19 July 1823.
