Explanation:

A proclamation imposing President’s Rule must be approved by both the Houses of Parliament within two months from the date of its issue.
If approved by both the Houses of Parliament, the President’s Rule continues for six months. It can be extended for a maximum period of three years with the approval of the Parliament, every six months. However, if the dissolution of the Lok Sabha takes place during the period of six months without approving the further continuation of the President’s Rule, then the proclamation survives until 30 days from the first sitting of the Lok Sabha after its reconstitution, provided the Rajya Sabha has in the meantime approved its continuance.
