14 While it is true, as counsel for the first respondents has pointed out, that the appellant has not, either here or below, taken any jurisdictional point and, indeed, originally submitted that no quarrel was taken with the order, made by the judge below, that the appellant should cease representing the second respondents, this cannot alter the fact that, to the extent that the court below lacked jurisdiction, the proceedings were a nullity. There was simply no statutory authorisation for them. Consent does not operate to waive a nullity, or to create jurisdiction (see Mason v Ryan (1884) 10 VLR 335 at 339) and it was the duty of the Judge below to satisfy herself that she had jurisdiction. (See R v Blakeley; Ex parte The Association of Architects, Engineers, Surveyors and Draughtsmen of Australia [1950] HCA 40; (1950) 82 CLR 54 at 90 - 91 and Danae Investment Trust Plc v MacIntosh Nominees Pty Ltd (1993) 10 ACSR 1 and 5). That being so, it seems to me, this Court is obliged itself to take notice of the fact of that absence of jurisdiction. (See also, in this respect, O 63 r 10(2) of the Rules of the Supreme Court 1971.)
