159. (1) If at any time when the Legislature of a Province is not in session the Governor is satisfied that circumstances exist which render it necessary for him to take immediate action, he may promulgate such Ordinances as the circumstances appear to him to require:
Provided that the Governor shall not, without instructions from the President, promulgate any such Ordinance if an Act of the Provincial Legislature containing the same provisions would under the provisions of this Constitution have been invalid unless, having been reserved for the consideration of the President, it had received the assent of the President.
(2) An Ordinance promulgated under this section shall have the same force and effect as an Act of the Provincial Legislature assented to by the Governor, but every such Ordinance-
(a) shall be laid before the Provincial Legislature and shall cease to operate at the expiration of weeks from the reassembly of the Legislature or if before the expiration of that period a resolution disapproving it is passed by the Legislative Assembly and agreed to by the Legislative Council, if any. upon the passing of the resolution or, as the ease may be, on the resolution being agreed to by the Council; and
(b) may be withdrawn at any time by the Governor.
(3) If and so far as an Ordinance under this section makes any provision which would not be valid if enacted in an Act of the Provincial Legislature assented to by the Governor, it shall be void:
Provided that, for the purposes of the provisions oi this Constitution relating to the effect of an Act of a Provincial Legislature which is repugnant to an Act of the Federal Parliament or an existing law with respect matter enumerated in the Concurrent Legislative List, an Ordinance promulgated under this section in pursuance of instructions from the President shall be deemed to be an Act of the Provincial Legislature which has been reserved for the consideration of the President and assented to by him.
