His Honour apparently relied on the rule which has prevailed since Montague (Lord) v. Dudman [1] that a bill of discovery lies to "aid the proceeding in some suit relating to a civil right in a court of common law, as an action; but not to aid the prosecution of an indictment or information, or to aid the defence to it" [2] . But his Honour did not refer to any authority. In Robertson, Civil Proceedings by and against the Crown, at p. 174 it is stated that informations for penalties are to be regarded rather as civil than as criminal proceedings. In Attorney-General v. Freer [3] , Graham B. said: "I think that the Attorney-General is perfectly right when he says that these proceedings for penalties here, are although partly of a criminal nature, for many purposes to be considered as in the nature of civil actions" [4] . In R. v. McStay [5] Williams J. said that proceedings under Pt. VII. are not strictly criminal proceedings, a view he adhered to in McGovern v. Hillman Tobacco Pty. Ltd. [6] where, after citing s. 237 of the Act, he said: "Accordingly, proceedings must, for many purposes, be considered as being in the nature of a civil action" [7] . In Jackson v. Butterworth [8] Fullagar J., who was then a judge of the Supreme Court of Victoria, held that proceedings under Pt. VII. are civil rather than criminal in their nature, an opinion he adhered to in Jackson v. Gromann [9] . The question was touched upon by the Full Court consisting of Latham C.J., Dixon J. (as he then was) and McTiernan J. in Mallan v. Lee [10] but nothing decisive was said. Latham C.J. expressed the view that the proceedings might assume a civil form or a criminal form. He said: "If proceedings are instituted in a court of summary jurisdiction (as in the present case) there is nothing to distinguish the proceedings from any other proceedings for an offence. If proceedings were instituted in the Supreme Court or the High Court they might assume a civil form or, in accordance with the directions of the Judge, a form more nearly approaching to that of criminal proceedings" [1] . Dixon J. did not discuss the question. McTiernan J. said [2] that it had been argued that the understating of income in breach of s. 230 could not be aided and abetted in the proper sense of the words because the understatement did not amount to the commission of a crime. He then said: "The argument is based upon other sections of the Act providing procedure which is more appropriate to civil than to criminal matters, for the prosecution of "offences" against the Act. The authorities which have been cited in connection with this argument do not enable a clear conclusion to be reached that such procedural provisions alter the character which the words, "guilty of an offence", naturally ascribe to the conduct of understating income in breach of s. 230. I think that the better test is to accept the legislative definition of the conduct: I should hold accordingly that it is an offence and is criminal" [3] . We are here primarily concerned with the sections in Pt. VII. relating to the procedure laid down for the recovery of pecuniary penalties for offences and not with the nature of the offences themselves and nothing that was held in Mallan v. Lee [4] throws any doubt upon the remarks of Williams J. and Fullagar J. in the cases cited. The most that can be said is that the proceedings being for the recovery of penalties are of a penal nature. It is clear that the actual procedure by which an order for the recovery of a penalty is obtained in this Court is, in the absence of a special order, the civil procedure of this Court. This is expressly provided for by s. 237 of the Assessment Act. Discovery and the administration of interrogatories are part of the ordinary civil procedure of the Court. The practice is now regulated by O. 32 of the Rules of Court. Originally orders for discovery were not obtainable at common law, except to a limited extent, and a party to a common law action who desired general discovery had to proceed by bill in equity. But the Court of Equity would not make an order for discovery or for the administration of interrogatories in favour of the prosecutor whether the prosecutor was the Crown or a common informer or any other person where the proceeding was of such a nature that it might result in a penalty or forfeiture: " nemo tenetur seipsum prodere ". When discovery and interrogatories were provided for under the rules made under the Judicature Act the same principle was applied. It was held that the orders were not intended to confer a right to discovery, Hunnings v. Williamson [1] ; or to administer interrogatories, Martin v. Treacher [2] , where prior to the Judicature Act such orders were not obtainable. See also Mexborough (Earl) v. Whitwood Urban District Council [3] ; Colne Valley Water Co. v. Watford & St. Albans Gas Co. [4] . The subject is discussed in the judgment of Isaacs J., as he then was, in R. v. Associated Northern Collieries [5] . The proceedings there in question were brought under s. 13 (1) of the Australian Industries Preservation Act 1906-1910 which provided that proceedings for the recovery of pecuniary penalties for offences, other than certain offences, should be instituted in the High Court by way of civil action and should be tried before a justice of that Court without a jury. His Honour held that in a civil action for penalties, in the absence of statutory provision to the contrary, the plaintiff is not entitled to an order for discovery of documents against the defendant and that this rule applies equally both to actions by the Crown and actions by a common informer.
