South Australian Cold Stores Ltd v Electricity Trust (SA) [1957] HCA 69

South Australian Cold Stores Ltd v Electricity Trust (SA) [1957] HCA 69

The Prices Commissioner's document was ineffective because it was not gazetted and did not specify a day on which it was to come into operation as required by s. 44. The increased rates therefore were not lawfully chargeable. However, the company's earlier payments at the increased rates were not recoverable or available as a set-off because they were made without inquiry on an assumption that the charges were lawful, not under a relevant mistake of fact. The Trust was entitled only to the unpaid balance calculated at the old lawful rates, accepted by the parties as £3,211.

Appeal Concerning Recovery of Electricity Supply Charges and the Validity of a Prices Order / Appeal to the High Court of Australia From a Judgment of the Supreme Court of South Australia

Legal Issues

  1. 1 ["Whether the Prices Commissioner's document validly fixed increased maximum rates for electricity supplied by the Electricity Trust." 'Whether the document specified a commencement day as required where it was not published in the Gazette.' 'Whether the document impermissibly operated retrospectively on electricity already supplied.' 'Whether South Australian Cold Stores Ltd. could recover or set off prior overpayments as money paid under a mistake of fact.' 'What amount the Electricity Trust was entitled to recover for electricity supplied during December 1952 and January and February 1953.']

Ratio Decidendi

The Prices Commissioner's document was ineffective because it was not gazetted and did not specify a day on which it was to come into operation as required by s. 44. The increased rates therefore were not lawfully chargeable. However, the company's earlier payments at the increased rates were not recoverable or available as a set-off because they were made without inquiry on an assumption that the charges were lawful, not under a relevant mistake of fact. The Trust was entitled only to the unpaid balance calculated at the old lawful rates, accepted by the parties as £3,211.

Court Disposition

Appeal allowed with costs; judgment for the Electricity Trust reduced to £3,211; no order as to costs in the Supreme Court.
