The Northern Territory of Australia v Sangare

The Northern Territory of Australia (the Territory) appealed to the High Court of Australia against a decision of the Full Federal Court concerning the validity of a notice issued under section 19 of the *Aboriginal Land Rights (Northern Territory) Act 1976* (Cth) (the Act). The notice, issued by the Minister for Indigenous Affairs, purported to withdraw certain land from the operation of the Act, thereby removing it from the definition of "Aboriginal land" for the purposes of the Act. The primary dispute concerned whether the Minister had the power to issue such a notice and, if so, under what conditions.

The central legal issue before the High Court was whether the Minister's power to withdraw land from the operation of the Act under section 19 was conditioned upon the land being used for a purpose specified in section 19(1)(a) or (b) of the Act, or whether the Minister had an unfettered discretion to withdraw land for any reason. The High Court was required to interpret the scope and limitations of the Minister's power under section 19, particularly in light of the purpose of the Act, which is to provide for the granting of traditional Aboriginal land in the Northern Territory.

Gageler J, in his reasons, considered the text and purpose of section 19 of the Act. His Honour concluded that the power to withdraw land under section 19 was not unfettered. Instead, the power was exercisable only for the purposes specified in section 19(1)(a) and (b), which relate to the land being used for a purpose other than traditional Aboriginal ownership or occupation. The Minister's decision to withdraw the land was therefore vitiated by a failure to exercise the power for the proper purpose.

The appeal was dismissed, with the High Court upholding the Full Federal Court's decision that the notice issued under section 19 was invalid.
