[21. Validation of requisition orders.- (1) Notwithstanding anything contained in this Act, or a judgment, decree or order of a Court if any order for requisition made under section 5, 6 or 7 on or after the 26 January 1950 and before the commencement of the Bombay Land Requisition (Amendment) Act, 1951 (Bom. XL of 1951), has not specified the purpose for which such requisition was made, but if such order for requisition was in fact made for the purpose of the State or any other public purpose, such order shall not be deemed to be or ever to have been invalid, nor shall such order be called in question in any Court merely on the ground that the order has not specified the purpose for which the requisition was made.
(2) Nothing contained in this section shall-
(a) affect the judgment, decree or order of any competent Court passed before the 31 August 1951 holding any such order invalid on the ground specified in sub-section (1), or
(b) preclude any Court from requiring the State Government or the officer who made such order for requisition to produce before it evidence to show that the order for requisition was in fact made for the purpose of the State or any other public purpose.
