What powers does the federal government retain over Australian Capital Territory legislation?

The federal government of Australia retains significant authority over the Australian Capital Territory (A.C.T.), distinct from its relationship with the Australian states. While the territory has operated under its own Legislative Assembly since 1989, the federal government holds a formal veto power over any legislation passed by the territory government.1

Additionally, the federal government maintains direct control over planning and development in specific areas designated as having national significance. While planning and development responsibilities were divided between the federal and territory governments following the abolition of the National Capital Development Commission in 1988, the federal government's overarching veto power ensures it retains ultimate oversight of the territory's legislative output.12
