The ADJR Act
14. The ADJR Act provides a scheme for administrative review by the Federal Court of Australia of federal decisions "… of an administrative character made, … under [a federal] enactment": see ADJR Act, s 3(1). The grounds of review are specified in s 5(1). They include that the decision was not authorised by the enactment in pursuance of which it was purported to be made: subs 5(1)(d); that the decision involved an error of law, whether or not the error appears on the record of the decision: subs 5(1)(f); and that there was no evidence or other material to justify the making of the decision: subs 5(1)(h). The ground under subs 5(1)(h) is not taken to be made out unless, inter alia, the decision maker based the decision on the existence of a particular fact and that fact did not exist: see subs 5(3)(b). In administrative law terms such a fact is categorised as a jurisdictional fact. In Timbarra Protection Coalition Inc v Ross Mining NL & Ors [1999] NSWCA 8 the New South Wales Court of Appeal extensively reviewed what constitutes a jurisdictional fact. Spigelman CJ said at 14-15:
"The issue of jurisdictional fact turns, and turns only, on the proper construction of the Statute. (See e.g. Ex Parte Redgrave; Re Bennett (1946) 46 SR (NSW) 122, 125). The Parliament can make any fact a jurisdictional fact, in the relevant sense: that it must exist in fact ('objectivity') and that the legislature intends that the absence or presence of the fact will invalidate action under the statute ('essentiality').
