(2) A suit to obtain an urgent or immediate relief against the Government (including the Government of the State of Jammu and Kashmir) or any public officer in respect of any act purporting to be done by such public officer in his official capacity, may be instituted, with the leave of the court, without serving any notice as required by sub-section (1); but the court shall not grant relief in the suit, whether interim or otherwise, except after giving to the Government or public officer, as the case may be, a reasonable opportunity of showing cause in respect of the relief prayed for in the suit:
