Can the validity of an order or instrument authenticated in the name of the President be questioned on the ground that it was not made or executed by the President?
No, the validity of an order or instrument authenticated in the name of the President cannot be questioned on the ground that it was not made or executed by the President. This is stated in Article 77 (2), which specifies that "The President shall make rules for the more convenient transaction of the business of the Government of India, and for the allocation among Ministers of the said business." Furthermore, the validity of an order or instrument which is authenticated as per these rules "shall not be called in question on the ground that it is not an order or instrument made or executed by the President."
