How can a Proclamation of Emergency be issued, varied, or revoked under Article 352?
Under Article 352, the President can issue a Proclamation of Emergency if satisfied that a grave emergency exists. The President can also vary or revoke a Proclamation through a subsequent Proclamation. However, the President cannot issue, vary, or revoke a Proclamation unless the Union Cabinet's decision to do so has been communicated to him in writing. Every Proclamation must be laid before each House of Parliament, and it will cease to operate at the expiration of one month unless approved by resolutions of both Houses of Parliament.
