Explanation:

Under the Constitution, a person shall be disqualified for being elected as a member of Parliament:
•If he holds any office of profit under the Union or state government (except that of a minister or any other office exempted by Parliament). Holding government contracts amounts to office of profit.
•If he is of unsound mind and stands so declared by a court.
•If he is an undischarged insolvent.
•If he is not a citizen of India or has voluntarily acquired the citizenship of a foreign state or is under any acknowledgement of allegiance to a foreign state; and
•If he is so disqualified under any law made by parliament.
A member incurs disqualification under the defection law:
•If he voluntary gives up the membership of the political party on whose ticket he is elected to the House;
•If he votes or abstains from voting in the House contrary to any direction given by his political party;
•If any independently elected member joins any political party; and
•If any nominated member joins any political party after the expiry of six months.
