10 Both Commissioners and Registrars exercise the functions of the Court pursuant to powers delegated to them from the Chief Judge. For a Registrar, that delegation arises pursuant to section 13 of the Civil Procedure Act 2005. That delegation gives the Registrar a quasi-judicial function. For a Commissioner, that delegation arises pursuant to section 36 of the Land and Environment Court Act 1979. Commissioners are statutory officers appointed under that Act but are not, strictly speaking, judicial officers. There are some powers that are exercisable by Commissioners that are not exercisable by a Registrar. For example, a Commissioner can make a final determination in proceedings falling in Classes 1, 2 and 3 of the Court's jurisdiction. Indeed, that is the primary function of their role. Conversely, there are powers that are exercisable by the Registrar that are not exercisable by a Commissioner. For example, a Registrar has the delegation to make a general order for costs whereas such an order is not within the power of a Commissioner.
