"If such an administrative tribunal falls into an error of law which causes it to identify a wrong issue, to ask itself a wrong question, to ignore relevant material, to rely on irrelevant material or, at least in some circumstances, to make an erroneous finding or to reach a mistaken conclusion, and the tribunal's exercise or purported exercise of power is thereby affected, it exceeds its authority or powers. Such an error of law is jurisdictional error which will invalidate any order or decision of the tribunal which reflects it."
5 This was later clarified in the case of Minister for Immigration and Multicultural Affairs v Yusuf (2001) 206 CLR 323 at 351:
""Jurisdictional error" can thus be seen to embrace a number of different kinds of error, the list of which, in the passage cited from Craig , is not exhaustive. Those different kinds of error may well overlap. The circumstances of a particular case may permit more than one characterisation of the error identified, for example, as the decision-maker both asking the wrong question and ignoring relevant material. What is important, however, is that identifying a wrong issue, asking a wrong question, ignoring relevant material or relying on irrelevant material in a way that affects the exercise of power is to make an error of law. Further, doing so results in the decision-maker exceeding the authority or powers given by the relevant statute. In other words, if an error of those types is made, the decision-maker did not have authority to make the decision that was made; he or she did not have jurisdiction to make it."
6 There have been a number of decisions of this Court which canvass judicial review in relation to the decision of the Registrar of the Workers Compensation Commission which have been referred to in Zuanic v Gypro-Tech (Australia) Pty Limited (in Liq) & Ors (2006) NSWLR 206 at [53]-[55].
7 In any event, I have some reservation that this Court is entitled to interfere with a decision of the Registrar made under s 327 of the Workplace Injury Management and Workers Compensation Act 1998 (NSW) ('WIMWCA'). There are two other relevant sections of the WIMWCA, namely ss 350 and 375.
8 Section 350 reads:
"Decisions of Commission
(1) Except as otherwise provided by this Act, a decision of the Commission under the Workers Compensation Acts is final and binding on the parties and is not subject to appeal or review.
(2) A decision of or proceeding before the Commission is not:
…
(b) liable to be challenged, appealed against, reviewed, quashed or called into question by any court.
(3) …"
9 Section 375 relevantly reads:
"Constitution of Commission for particular proceedings
(4) The Registrar does not constitute, and does not exercise functions as, the Commission (except when acting as an Arbitrator pursuant to the Registrar's power to exercise the functions of an Arbitrator)."
10 Wood CJ at CL said in Campbelltown City Council v Vegan [2004] NSWSC 1129, at [33]
"The term "the Commission", it seems to me, should be understood in accordance with such content as is given to that expression by ss 4, 366, 368 and 375 of the Act. As such I consider that it means the Commission as constituted either by an arbitrator or by a Presidential Member, and that it does not mean an Appeal Panel. "
11 Wood CJ at CL's approach prevents the operation of s 350 from making a decision of the Appeal Panel unreviewable by this Court. However, if the decisions of a Registrar or of an Appeal Panel are not decisions of the Commission, it is difficult to see how such decisions could be decisions of a "court or tribunal", so as to allow relief being granted by this Court pursuant to s 69(3) of the SCA.
12 On the other hand, if I adopt the view that the Registrar exercises the power of a court or tribunal, then the privative clause contained in s 350 of the WIMWCA operates to exclude the jurisdiction of this Court. Section 69(5) of the SCA by its terms means that the privative clause would prevent the operation of s 69(3).
13 The issue of jurisdiction was not ventilated before me, and for reasons of comity, I will assume that this Court has jurisdiction to hear this matter pursuant to s 69 (3) of the SCA.
