Sub-section (3) of s. 113 provides that an appeal does not lie to the High Court from a judgment decree order or sentence from which an appeal may be brought to the Court under sub-s. (1) of the section. It seems evident that the words "does not lie" mean that the appeal shall not lie as of right or by special leave. If this provision be within the legislative power of the Parliament, part of its operation must be to exclude cases within sub-s. (1) from the application of pars. (b) and (c) of s. 39 (2) of the Judiciary Act 1903-1955. These form "conditions" "subject to" which federal jurisdiction is expressed to be conferred by sub-s. (2) upon State courts. But it would seem that the intention of sub-s. (3) of s. 113 of the Conciliation and Arbitration Act 1904-1956 is impliedly to repeal pro tanto the "conditions" and not to extend the implied repeal into the affirmative investment of federal jurisdiction accomplished, as was decided in Lorenzo v. Carey [1] , by the body of sub-s. (2) of s. 39 of the Judiciary Act. If it were otherwise the operation of sub-s. (1) of s. 113 of the Conciliation and Arbitration Act 1904-1956 might be much restricted. For but for s. 39 (2) State courts would not exercise federal jurisdiction in many cases in which they entertained a matter arising under the Conciliation and Arbitration Act. It will be seen from the text of sub-s. (3) that its scope is coextensive with sub-s. (1), that is to say there is to be no appeal to this Court "from a judgment decree order or sentence from which an appeal may be brought to the Commonwealth Industrial Court under sub-s. (1) of this section". It is therefore necessary to turn to sub-s. (1). That sub-section provides that the Commonwealth Industrial Court has jurisdiction to hear and determine an appeal from a judgment decree order or sentence of a State court (not being a Supreme Court) or of a court of a Territory of the Commonwealth made given or pronounced in a matter arising under (a) the Conciliation and Arbitration Act; or (b) the Public Service Arbitration Act. It is convenient in what follows to disregard par. (b) which does not affect the matter. We may put aside the reference to a court of a Territory. Presumably that part of sub-s. (1) is based on the doctrine of Porter v. The King; Ex parte Yee [2] and depends on the application of that doctrine to the Commonwealth Industrial Court. The doctrine is discussed in the case of Reg. v. Kirby; Ex parte Boilermakers' Society of Australia [3] . There may be a different basis for the Capital Territory but for present purposes that too can be put on one side. These are not matters which can affect the portion of the sub-section which here matters. It is there expressed to confer on the Commonwealth Industrial Court jurisdiction to hear and determine appeals from an order of a State court. The legislative power authorising this must be found in s. 77 of the Constitution. Section 71 no doubt authorises the creation of a federal court, but in spite of occasional judicial observations that may possibly suggest the contrary the jurisdiction which a federal court so created may exercise cannot come from s. 71 alone. It must be conferred and defined by the exercise of further legislative power. When s. 1, s. 61 and s. 71 of the Constitution say the legislative executive and judicial powers of the Commonwealth shall be vested in the respective repositories of those powers they mean in accordance with the provisions that follow. When you turn to s. 77 and read it with ss. 75 and 76, the impression that s. 77 is dealing with original jurisdiction is very strong. The legislative power it confers is confined to the matters which are actual or possible subjects of original jurisdiction in the High Court, they are described by reference to ss. 75 and 76 and in the very next section, s. 78, they seem again to be referred to under the description "matters within the limits of the judicial power". The appellate power conferred by s. 73 is not concerned with "matters" but with judgments decrees orders and sentences of the courts and the commission which it identifies. But the view that s. 77 relates to original jurisdiction only was rejected by this Court early in its history: Ah Yick v. Lehmert [1] ; see the discussion by Taylor J. in Collins v. Charles Marshall Pty. Ltd. [2] . It is true that the court in rejecting that view was concerned only with s. 77 (iii.). But if it be true of that paragraph of s. 77 it must be true of the whole section. The decision in Ah Yick v. Lehmert [1] gave an operation to s. 39 (2) which has been acted upon very often indeed and whatever difficulty one may feel about finding a justification for it in the text of ss. 75 to 78 it should be accepted in its application to s. 113 (1) of the Conciliation and Arbitration Act. But as was pointed out in Collins v. Charles Marshall Pty. Ltd. [3] when you come to apply s. 77 with reference to appellate jurisdiction it is important to notice that, on the very terms of the section, the legislative power it confers must be exercised "with respect to any of the matters mentioned in" ss. 75 and 76. The validity of sub-s. (1) of s. 113 of the Conciliation and Arbitration Act, if it is to be sustained at all must be sustained under par. (i.) of s. 77 in relation to s. 76 (ii.) of the Constitution. That means that s. 113 (1) must amount to an exercise of a power, with respect to a matter or matters arising under a law made by the Parliament (namely the Conciliation and Arbitration Act), to make laws defining the jurisdiction of a federal court, that is to say of the Commonwealth Industrial Court. Section 113 (1) does not go directly to the "matter". It does not say that if the decision of the court below involves a matter arising under the Conciliation and Arbitration Act, there may be an appeal. It defines the jurisdiction by reference to judgments orders etc. but it defines the judgments orders etc. in terms requiring that they should be given in a matter arising under the Act. Is that the same thing? The answer must be that usually it will be the same thing but that cases may occur where it is not. Take as an example this very case. Suppose the magistrate had dismissed the informations on the ground that s. 138 was void, that it was no part of the Act. Would an appeal against such a dismissal be a matter arising under the Conciliation and Arbitration Act? Again, suppose that there is a proceeding under s. 123 in a State court on a count of work and labour done for the recovery of wages to which the defendant pleads by way of confession and avoidance, for example a plea of payment. If his defence is unsuccessful and he appeals against the finding that his plea is not made out, is that in itself a "matter arising under" the Conciliation and Arbitration Act? Take still another example. Suppose that upon an information in a State court for an offence under a provision of the Conciliation and Arbitration Act the magistrate considers that it is not proved that the defendant was himself a principal offender but convicts him on the strength of s. 5 of the Crimes Act 1914-1955, or convicts him of an attempt under s. 7 of that Act. Is an appeal from that conviction itself a matter arising under the Conciliation and Arbitration Act? It seems clear enough in the case of each of these examples that the order was made or the judgment given by the court below "in a matter arising under" that Act. But does the appeal involve such a "matter"? The distinction between an appeal which itself involves a matter arising under a given federal statute and an appeal from a judgment or order pronounced or made in such a matter may seem neither wide nor frequent in its practical applications, but its existence can scarcely be denied. Perhaps the fact is that, for the very reason that s. 77 really relates only to original jurisdiction, the conception of an appeal per se involving any of the matters mentioned in ss. 75 and 76, as distinguished from the proceeding in the court below doing so, is foreign to the constitutional provision. But when it was decided that s. 77 applied to appellate jurisdiction it necessarily followed that the appellate jurisdiction conferred under s. 77 (i.) must be defined by reference to one or other or more of the matters set out in ss. 75 and 76. Does it follow that s. 113 (1) is framed in such a way that it cannot be sustained? With some misgiving we have come to the conclusion that the sub-section can be sustained as a law substantially with respect to matters arising under a federal law (namely the Conciliation and Arbitration Act) conferring jurisdiction in respect of such matters. At the same time it cannot be denied that the law is one going, or possibly going, beyond that category. The provision however is distributable and s. 15A of the Acts Interpretation Act will operate to confine its operation to appeals which themselves come within s. 77 (i.) of the Constitution. The central point is whether the section sufficiently manifests an intention to legislate with respect to a matter within s. 76 (ii.) and, on the whole we think that it does so, although owing to the form in which the sub-section is cast it may include cases outside the required description. Accepting the validity in substance of sub-s. (1) of s. 113, a basis is provided for the operation of sub-s. (3). If an appeal is of the class properly falling within sub-s. (1) then according to sub-s. (3) it is not an appeal that lies to this Court. The provision must rest for its validity upon the words in s. 73 of the Constitution which authorise exceptions. Section 73 begins - "The High Court shall have jurisdiction, with such exceptions and subject to such regulations as the Parliament prescribes, to hear and determine appeals from all judgments, decrees, orders, and sentences"; then follow the descriptions of judgments etc. from which an appeal is to lie. It is upon the legislative power to prescribe exceptions that sub-s. (3) rests. An exception assumes a general rule or proposition and specifies a particular case or description of case which would be subsumed under the rule or proposition but which, because it possesses special features or characteristics, is to be excluded from the application of the rule or proposition. It is not a conception that can be defined in the abstract with exactness or applied with precision; it must depend very much upon context. Section 73 defines the appellate jurisdiction of this Court by reference to the judgments decrees orders and sentences from which there are to be appeals. In every case the judgments decrees orders and sentences are defined by reference to the courts or tribunals by which they are given made or pronounced. In the case of each description of court or tribunal the intention of s. 73 doubtless is that the general rule shall be that the High Court has jurisdiction to hear and determine appeals from its judgments decrees orders or sentences. From that general rule the legislation is empowered to prescribe exceptions. In the present case there is no attempt to use the power to prescribe exceptions so as to destroy the general rule, in relation to any court or tribunal or class of courts or tribunals comprised within s. 73, that an appeal shall lie from its judgments decrees orders or sentences. The class of judgments etc. with which s. 113 (3) is concerned is included within that part of par. (ii.) of s. 73 which relates to the judgments decrees orders or sentences of any court exercising federal jurisdiction. It concerns State courts exercising federal jurisdiction; but the judgments decrees orders or sentences of these courts which are to be excepted are those which involve a matter arising under the Conciliation and Arbitration Act. What that means is a question dealt with in the earlier part of this judgment in the course of the discussion of the validity of sub-s. (1) of s. 113. Does that amount to prescribing an exception or exceptions under s. 73? It will be noted that the judgments etc. to be excepted are described not by reference to the courts giving them save that ex hypothesi they must be State courts exercising federal jurisdiction and must not be Supreme Courts. From what has been said about sub-s. (1) of s. 113 it will be seen that upon analysis the judgments etc. are really defined by reference to the matter involved in the appeal, that is to say by reference to the fact that a matter arising under the Conciliation and Arbitration Act is involved in the appeal from the judgment etc. It is difficult to see why that should be an inadmissible ground of exception. The ground relates directly to the judgment etc. as something either actually inherent in it or alleged by the appellant to be inherent in it. It is true that it relates rather to its legal basis than its operative effect as between the parties, its pecuniary significance, its finality or its interlocutory character. But familiar as these are as grounds for restricting or regulating appeals from judgments orders etc. they are not exhaustive. It is not desirable to go beyond the precise ground of exception which s. 113 (3) appears to take. It is enough to say that it fixes upon a description of judgment decree order or sentence of State courts exercising federal jurisdiction, it does not eat up or destroy the general rule laid down by the Constitution that appeals shall lie to this Court from judgments decrees orders and sentences of courts of a State exercising federal jurisdiction, and the description upon which it fixes, though it relates to the "matter" involved in the appeal, goes to the basis or alleged basis of the judgment decree order or sentence and forms a ground of exception within the power of prescribing exceptions which the Parliament obtains under s. 73.
