(3) Every rule under this Act shall be laid before each House of Parliament forthwith, and, if any address is presented to His Majesty by either House of Parliament within the next subsequent thirty days on which the House has sat next after any such rule is laid before it, praying that the rule may be annulled, His Majesty in Council may annul the rule, and it shall thenceforth be void, but without prejudice to the validity of anything previously done thereunder. SUPPLEMENTAL =19.= Nothing in this Act shall affect the prerogative of mercy, but the Secretary of State on the consideration of any petition for the exercise of His Majesty’s mercy, having reference to the conviction of a person on indictment or to the sentence (other than sentence of death) passed on a person so convicted, may, if he thinks fit, at any time either-- (_a_) refer the whole case to the Court of Criminal Appeal, and the case shall then be heard and determined by the Court of Criminal Appeal as in the case of an appeal by a person convicted, or (_b_) if he desires the assistance of the Court of Criminal Appeal on any point arising in the case with a view to the determination of the petition, refer that point to the Court of Criminal Appeal for their opinion thereon, and the Court shall consider the point so referred and furnish the Secretary of State with their opinion thereon accordingly. =20.= (1) Writs of error, and the powers and practice now existing in the High Court in respect of motions for new trials or the granting thereof in criminal cases, are hereby abolished. (2) This Act shall apply in the case of convictions on criminal informations and coroners’ inquisitions and in cases where a person is dealt with by a court of quarter sessions as an incorrigible rogue under the Vagrancy Act, 1824, as it applies in the case of convictions on indictments, but shall not apply in the case of convictions on indictments or inquisitions charging any peer or peeress, or other person claiming the privilege of peerage, with any offence not now lawfully triable by a court of assize. (3) Notwithstanding anything in any other Act, an appeal shall lie from a conviction on indictment at common law in relation to the non-repair or obstruction of any highway, public bridge, or navigable river in whatever court the indictment is tried, in all respects as though the conviction were a verdict in a civil action tried at assize, and shall not lie under this Act.
