Timbarra Protection Coalition Inc v Ross Mining NL

Timbarra Protection Coalition Inc (the appellant) appealed to the Supreme Court of New South Wales, Court of Appeal, against a decision of the Land and Environment Court concerning the validity of a mining project. The dispute centred on whether a particular factual condition, referred to in section 77(3)(d1) of the *Environmental Planning and Assessment Act 1979* (NSW), constituted a "jurisdictional fact" for the purposes of the Act.

The Court of Appeal was required to determine the correct interpretation of section 77(3)(d1) of the *Environmental Planning and Assessment Act 1979* and, in particular, whether the satisfaction of the condition stipulated therein was a prerequisite to the exercise of the Minister's power to grant approval for the mining project. This involved considering the nature of "jurisdictional facts" in administrative law and how they operate to limit or define the scope of statutory powers.

The Court reasoned that the language of section 77(3)(d1) indicated that the condition was intended to be a jurisdictional fact. Spigelman CJ, Mason P and Meagher JA held that if the condition was not satisfied, the Minister lacked the power to grant the approval. The Court applied principles of statutory interpretation to ascertain the legislative intent, concluding that the condition was a threshold requirement that had to be met before the Minister could validly exercise their discretion.

Consequently, the Court of Appeal allowed the appeal, set aside the decision of the Land and Environment Court, and remitted the matter to that court for redetermination in accordance with the Court of Appeal's reasons. The respondent was ordered to pay the costs of the appellant in both the Court of Appeal and the Land and Environment Court.
