Under what condition can the President promulgate any such Ordinance?
The President can promulgate any such Ordinance if it meets the criteria outlined in Article 213(1) of the Indian Constitution. Specifically, the Governor must be satisfied that circumstances exist which render it necessary for him to take immediate action, and one of the following conditions must apply:

(a) A Bill containing the same provisions would under this Constitution have required the previous sanction of the President for the introduction thereof into the Legislature.
(b) The Governor would have deemed it necessary to reserve a Bill containing the same provisions for the consideration of the President.
(c) An Act of the Legislature of the State containing the same provisions would under this Constitution have been invalid unless, having been reserved for the consideration of the President, it had received the assent of the President.
