A territorial commissioner is the federal government's representative in each territory, similar to how lieutenant governors represent the Crown in provinces. Commissioners are appointed by the federal government and fulfill ceremonial roles like giving assent to territorial legislation. However, the commissioner's role reflects territories' different constitutional status—they represent federal authority rather than just the Crown. Historically commissioners had more active governing roles, but as territorial governments have developed, the position has become increasingly ceremonial. The commissioner works alongside elected territorial premiers and assemblies. The ongoing presence of federally-appointed commissioners reflects that territorial powers derive from federal delegation rather than constitutional right.
