Defence or stay instead of injunction or prohibition

No cause or proceeding at any time pending in the Court shall be restrained by prohibition or injunction, but every matter of equity on which an injunction against the prosecution of any such cause or proceeding might formerly have been obtained, whether unconditionally or on any terms or conditions, may be relied on by way of defence thereto, Provided that26 (a) nothing in this Act shall disable the Court, if it thinks fit to do so, from directing a stay of proceedings in any cause or matter pending before it; and (b) any person, whether a party or not to any such cause or matter, who would formerly have been entitled to apply to any Court to restrain the prosecution thereof, or who may be entitled to enforce, by attachment or otherwise, any judgment, decree, rule or order, in contravention of which all or any part of the proceedings in the cause or matter have been taken, may apply to the Court, by motion in a summary way, for a stay of proceedings in the cause or matter, either generally, or so far as may be necessary for the purposes of justice, and the Court shall thereupon make such order as shall be just.
