NAOI v MIMIA

NAOI (the applicant) sought judicial review of a decision made by MIMIA (the respondent). The dispute concerned the respondent's refusal to grant the applicant a licence to operate a casino. The matter came before the High Court of Australia.

The primary legal issue before the High Court was whether the respondent's decision to refuse the licence was affected by an error of law, specifically whether the respondent had failed to take into account a relevant consideration or had taken into account an irrelevant consideration when making its decision.

McHugh and Heydon JJ found that the respondent had failed to consider a crucial piece of evidence that was relevant to the applicant's suitability to hold a casino licence. This failure constituted an error of law. The judges applied the principles of administrative law, particularly the grounds for judicial review concerning the proper exercise of statutory power. They emphasised that decision-makers must consider all relevant factors and disregard irrelevant ones.

The High Court ordered that the decision of the respondent be quashed and remitted to the respondent for reconsideration according to law.
