Explanation:

This question is based on the Supreme Court guidelines with regard to dissolution of a state assembly. The SC has laid down the following guidelines:

1.    presidential proclamation dissolving a state legislative assembly is subject to judicial review;

2.    if a state government works against secularism, president’s rule can be imposed,

3.    no wholesale dismissal of opposition ruled state governments when a new political party assumes power at the centre;

4.    if president’s rule is imposed only on political considerations the court can even restore the assembly;

5.    imposition of president’s rule and dissolution of state assembly cannot be done together

6.    state assembly can be dissolved only after parliament approves central rule;

7.    the Supreme court or a high court can compel the union government to disclose material on whose basis president’s rule is imposed on a state;

8.    the power of the president under Article 356 is a constitutional power , it is not an absolute power.

The existence of material is a pre-condition to form the satisfaction to impose the president’s rule.
