In which specific circumstances can a Proclamation of Emergency be declared for the whole or any part of a State?
A Proclamation of Emergency can be declared for the whole or any part of a State when a resolution with respect to the continuance in force of a Proclamation approved under clause (3) is passed by either House of Parliament, and when:

1. A Proclamation of Emergency is in operation in the whole of India or, as the case may be, in the whole or any part of the State at the time of passing the resolution.
2. The Election Commission certifies that the continuance in force of the Proclamation approved under clause (3) during the period specified in such resolution is necessary on account of difficulties in holding general elections to the Legislative Assembly of the State concerned.
