Powers

In 1978, the Northern Territory was granted limited self-government by the
Northern Territory (Administration) Act 1974' (Cth), an act of the
federal parliament. The federal government retains control of certain legislative areas, including Aboriginal land, industrial relations, national parks and uranium mining. For inter-governmental financial purposes the Northern Territory has been regarded by the Commonwealth as a State since 1 July 1988.
All questions arising in the Assembly are determined by a majority of votes and the Speaker, or other member presiding, is also entitled to vote. Where there is an equality of votes the Speaker, or other member presiding, shall have a casting vote.

Source of legislative power
The Legislative Assembly acting with the assent of the administrator is vested with general legislative power, similar to that of the state parliaments. The ''Northern Territory (Administration) Act 1974'' (Cth) granted self-government to the Territory. The federal government retains control of certain legislative areas, including Aboriginal land, industrial relations, national parks and uranium mining.
However, while the state parliaments derive their legislative powers from constitutional sources, the Northern Territory derives its legislative power from the delegation of powers from the Commonwealth. The

, both of which had a four-member Advisory Council that was half-elected and half-appointed; in addition, development of North Australia was left to the locally-based North Australia Commission. These changes were reversed in 1931, with the Northern Territory reformed and the federal government resuming control until the 1947 formation of the
Northern Territory Legislative Council, which was half-elected and half-appointed.
The Legislative Assembly was created in 1974 by the ''Northern Territory (Administration) Act 1974'' (Cth), an act of the Australian federal parliament, which was a fully-elected body in contrast to the Legislative Council. The Legislative Assembly consisted of 19 fully elected members, but initially lacked significant powers, until limited self-government was granted in 1978. For the
1983 election, the number of members was increased to 25.
