Commonwealth of Australia v Ling

The Commonwealth of Australia (the appellant) appealed to the High Court of Australia against a decision of the Federal Court of Australia concerning the validity of certain regulations made under the *Migration Act 1958* (Cth). The respondent, Mr Ling, was a citizen of Hong Kong who had entered Australia and sought to remain here. The dispute centred on the appellant's contention that the Federal Court had erred in finding that the regulations, which purported to prescribe the criteria for the grant of a protection visa, were invalid.

The High Court was required to determine whether the regulations, specifically Regulation 4.11A of the Migration Regulations, were beyond the scope of the power conferred by section 41(1) of the *Migration Act 1958* (Cth) to make regulations prescribing criteria for the grant of visas. The central legal question was whether the regulations, by requiring an applicant for a protection visa to satisfy criteria beyond those specified in the *Migration Act* itself, were ultra vires the enabling legislation.

The Court, comprising Brennan CJ, Toohey and Gummow JJ, held that the regulations were invalid. Their Honours reasoned that section 41(1) of the *Migration Act* did not grant the executive government a broad power to prescribe any criteria it wished for the grant of a visa. Instead, the power was limited to prescribing criteria that were relevant to the purpose of visa classification. The regulations, by imposing additional substantive requirements for the grant of a protection visa that were not contemplated by the Act, exceeded this limited power and were therefore beyond the scope of the legislative authority delegated to the Executive. The appeal was dismissed.
