Customs prosecutions for the recovery of penalties instituted under Pt. XIV of the Customs Act are proceedings instituted on behalf of her Majesty in right of the Commonwealth. In Anonymous [1] we find it said as far back as 1793 that "an information for the duties is nothing more than the king's action of debt" [2] . And in books such as Maddox's Exchequer and Gilbert's Exchequer we are told how the Court of Exchequer became the court to which all cases concerning the revenue, that is cases which touched the profits of the Crown, were removed for trial. Thus in Attorney-General v. Constable [3] Kelly C.B. said: "The case of the Attorney-General v. Barker [4] clearly shows that it was settled law before the Judicature Acts that it was part of the prerogative of the Crown that the Sovereign was entitled to be an actor in any litigation affecting the rights of the Crown, and to determine in the Court of Exchequer any matter in which the Crown is interested" [5] . Later, revenue cases were removed to the Exchequer Division and later still to the King's Bench Division of the High Court of Justice on its revenue side. By the Crown Suits &c. Act 1865, (28 & 29 Vict. Ch. 104), intituled an Act to amend the Procedure and Practice in Crown Suits in the Court of Exchequer at Westminster, provision was made for the practice and procedure of the Court of Exchequer in proceedings by English information in the Court of Exchequer and proceedings at law on the revenue side of that Court. Section 6 defined information to mean an information, styled an English information, exhibited in the Court of Exchequer in the name of Her Majesty's Attorney-General as the informant. In the Annual Practice 1912, vol. II, Pt. X, pp. 1097 et seq. notes appear upon the procedure and practice on the revenue side of the King's Bench Division. On p. 1098 of the notes, which were supplied by an officer of the King's Remembrancer's Department, Royal Courts of Justice, a form of information is set out, the title being "Between His Majesty's Attorney-General (on behalf of His Majesty) Informant and A.B., Defendant". Immediately under the title appear the words: "Information. To the Right Honourable (name) Lord Chief Justice of England, and to the rest of the Judges of the King's Bench Division of the High Court of Justice, Informing, showeth unto their Lordships, Sir A.B., Knight, His Majesty's Attorney-General on behalf of his Majesty as follows." The information then proceeds to state the facts of the case). Section 247 of the Customs Laws Consolidation Act 1876 provides that all suits, prosecutions, or informations for recovery of penalties under the Customs Acts in the High Court of Justice in England may be commenced either by writ of subpoena or capias as the first process at the election of the Commissioners of Customs, in which shall be specified the amount of the penalty or penalties sued for. The prosecution proceeded by way of information and it was not necessary that the information should be filed before the writ of capias issued: Attorney-General v. Reilly [1] . Order 68 of the rules of the Supreme Court in England excepts the procedure or practice in proceedings on the revenue side of the King's Bench Division of the High Court of Justice from the operation of these rules except to the extent provided for in that order. So that, as I understand it, it remained the practice in England for the Attorney-General to institute revenue proceedings on behalf of the Crown first in the Court of Exchequer, then in the Exchequer Division, and finally in the King's Bench Division on its revenue side by information until informations were abolished by the Crown Proceedings Act 1947. For present purposes the significant fact is that in the form of information set out on p. 1098 of the above notes the personal name of the Attorney-General appears - presumably in accordance with, as will appear, immemorial tradition and the requirement of the Crown Suits &c. Act 1865 that an information should be exhibited in the name of Her Majesty's Attorney-General.
