Explanation:

All the constitutional emergencies are subjected to judicial review.

1. The 38th Amendment Act of 1975 made the satisfaction of the President in invoking Article 356 final and conclusive which could not be challenged in any court on any ground. But, this provision was subsequently deleted by the 44th Amendment Act of 1978 implying that the satisfaction of the President is not beyond judicial review.

In Bommai case (1994), The Hon'ble Supreme Court held that the presidential proclamation imposing President’s Rule is subject to judicial review.

2. The 38th Amendment Act of 1975 made the satisfaction of the president in declaring a Financial Emergency final and conclusive and not questionable in any court on any ground. But, this provision was subsequently deleted by the 44th Amendment Act of 1978 implying that the satisfaction of the president is not beyond judicial review.

3. The 38th Amendment Act of 1975 made the declaration of a National Emergency immune from the judicial review. But, this provision was subsequently deleted by the 44th Amendment Act of 1978. Further, in the Minerva Mills case4, (1980), the Supreme Court held that the proclamation of a national emergency can be challenged in a court on the ground of malafide or that the declaration was based on wholly extraneous and irrelevant facts or is absurd or perverse.
