Sewerage Rates (Amendment) Act (No 2) 1982 (ACT)

In the Federal Court of Australia, the Sewerage Rates (Amendment) Act (No 2) 1982 (ACT) was challenged by the Sewerage Authority of the Australian Capital Territory. The dispute centered on the validity of the Sewerage Rates (Amendment) Ordinance (No 2) 1982 (ACT), which amended the Sewerage Rates Ordinance 1968 (ACT) to increase sewerage rates for the rating year starting 1 July 1982 and subsequent years. The Sewerage Authority argued that the Ordinance was beyond the legislative powers of the Australian Capital Territory (ACT) and exceeded the scope of the Seat of Government (Administration) Act 1910 (Cth).

The court was required to determine whether the Sewerage Rates (Amendment) Ordinance (No 2) 1982 (ACT) was within the legislative powers of the ACT and whether it exceeded the scope of the Seat of Government (Administration) Act 1910 (Cth). The key issue was whether the amendment of sewerage rates fell within the legislative powers granted to the ACT under the Commonwealth Constitution and the Seat of Government (Administration) Act 1910 (Cth). The Sewerage Authority contended that the amendment exceeded the legislative powers of the ACT, as sewerage rates were not a matter of exclusive state power and thus could not be regulated by the ACT.

The court held that the Sewerage Rates (Amendment) Ordinance (No 2) 1982 (ACT) was within the legislative powers of the ACT and did not exceed the scope of the Seat of Government (Administration) Act 1910 (Cth). The court reasoned that sewerage rates were a local matter and could be regulated by the ACT as part of its administrative powers. The amendment of sewerage rates was considered a valid exercise of the ACT's legislative powers, as it related to the administration of the ACT and did not infringe upon the exclusive legislative powers of the Commonwealth or the states. Consequently, the Sewerage Rates (Amendment) Ordinance (No 2) 1982 (ACT) was upheld as valid and binding.
