Amendment of Canberra Sewerage and Water Supply Regulations (ACT)

The case involved the Territory for the Seat of Government, with the Minister of State for the Interior, Thomas Paterson, as the respondent, and an individual or entity challenging the validity of the Amendment of Canberra Sewerage and Water Supply Regulations. The dispute centred around the power of the Minister to exempt certain land from payment of sewerage and water charges through a notice in the Gazette. The High Court of Australia was tasked with determining the legality of the regulation.

The primary legal issue before the court was whether the Minister had the authority under the Building and Services Ordinance 1924-1934 to create a regulation that allowed for the exemption of land used for church or school purposes from sewerage and water charges through a notice in the Gazette. The court had to consider the scope of the Minister's powers and whether such a regulation was consistent with the Ordinance.

The court examined the relevant provisions of the Ordinance and found that the Minister's power to make regulations was limited to matters necessary for the effective administration and control of building and services within the Territory. The court held that the regulation in question went beyond the scope of what was necessary and was thus invalid. The regulation was seen as an attempt to make policy decisions that should be left to Parliament, rather than merely implementing the provisions of the Ordinance.

The court's decision resulted in the invalidation of the regulation allowing the Minister to exempt land from sewerage and water charges through a notice in the Gazette. The court's ruling emphasised the importance of adhering to the legislative framework and respecting the division of powers between the executive and the legislature. No further orders were made by the court beyond the declaration of the invalidity of the regulation.
