The respondents were arrested under a special warrant issued pursuant to the Gaming and Betting Act 1912, sec. 40, and were brought before a Stipendiary Magistrate. The respondents Albert Bates and Nellie Isabel Bates were charged together with using a house as a common gaming house, and the respondent Saunderson was charged separately for that he was found in such house without lawful excuse. The Stipendiary Magistrate, by consent, heard both charges together and convicted the respondents. The respondents then appealed to Quarter Sessions and the learned Chairman stated a case for the determination of the Supreme Court of New South Wales. The question submitted by this case was answered in the Supreme Court by declaring "that as the Magistrate had no jurisdiction to hear the cases together the proceedings before such Magistrate were a nullity, and there was consequently no adjudication from which to appeal to the said Court of Quarter Sessions." Against this determination an appeal has been brought to this Court by special leave. The learned Judges of the Supreme Court were of opinion that the question submitted for their determination was governed by the decisions in R. v. Crane[1] and in R. v. Dennis[2]. We do not think it necessary to decide whether the Magistrate had, or had not, jurisdiction to hear these cases together, for we are unable to agree with the conclusion that if there was no jurisdiction there was no adjudication from which an appeal lay to the Court of Quarter Sessions; Crane's Case is, we think, a decisive authority to the contrary. It is desirable, however, to say that the cases of R. v. Biggins[3] and R. v. Justices of Staffordshire[4] will require consideration if the question of the jurisdiction of a magistrate to hear cases together by consent of the parties hereafter becomes of importance. The Magistrate had jurisdiction over the charges laid against the respondents and, even if what took place before him was no trial at all or a mistrial, nevertheless, to adapt the words of Lord Sumner, in Crane v. Public Prosecutor[5], the respondents were convicted and to all appearances convicted on the charges laid against them. The Justices Act 1902, sec. 122, provides that "every person who for any offence has by the conviction or order of a justice ... been adjudged to be imprisoned ... or to pay any fine ... may appeal to a Court of Quarter Sessions against such conviction. ..." Those words, to use Lord Atkinson's language in Crane v. Public Prosecutor[6], "cannot mean validly convicted, otherwise the statute would be futile and unworkable." "The very purpose" for which the appeal is given is "to consider whether the convictions of persons who had, in fact, been convicted were valid or the contrary, and to deal with them accordingly." Consequently, there was an adjudication from which an appeal lay to the Court of Quarter Sessions. The duty of the Court of Quarter Sessions was to determine the matter of the appeals and by its order confirm, quash, set aside, vary or reduce the conviction or sentence as to the Court seemed just. The word "quash" in sec. 125 is unlimited and confers the power which a superior Court could on certiorari exercise in respect of a conviction made without jurisdiction. The other words confer power beyond that exercisable on certiorari and include complete authority to determine the whole matter.
