Twenty-second Amendment to the United States Constitution
As worded, the primary focus of the 22nd Amendment is on limiting individuals twice elected to the presidency from being elected again. Due to this, several issues could be raised regarding the amendment's meaning and application, especially in relation to the 12th Amendment, ratified in 1804, which states, "But no person constitutionally ineligible to the office of President shall be eligible to that of Vice-President of the United States". While it is clear that under the 12th Amendment the original constitutional qualifications of age, citizenship, and residency apply to both the president and vice president, it is unclear whether someone who is ineligible to be elected president could be elected vice president. Because of this apparent ambiguity, there may be a loophole in the 22nd Amendment whereby a two-term former-president could be elected vice president and then succeed to the presidency as a result of the incumbent's death, resignation, or removal from office (or even succeed to the presidency from some other stated office in the presidential line of succession).
President's rule
In practice, president's rule has been imposed under different circumstances:If approved by both houses, President's Rule can continue for 6 months. It can be extended for a maximum of 3 years with the approval of the Parliament done every 6 months. If the Lok Sabha is dissolved during this time, the rule is valid for 30 days from the first sitting of the Lok Sabha provided that this continuance has already been approved by Rajya Sabha. The 44th Amendment Act of 1978 introduced a new provision to put a restraint on the power of the Parliament to extend President's rule in a state. According to this provision, President's rule can only be extended over a year every 6 months under following conditions:
President's rule can be revoked at any time by the President and does not need the Parliament's approval.
