What are the main provisions related to disqualification on the ground of defection according to the Tenth Schedule?
The Tenth Schedule provides for the disqualification of members on the ground of defection in the following manner:

1. Definition of defection: A member is deemed to have defected if they voluntarily give up their membership or support to a political party, or join another political party, without proper authorization from the party.

2. Disqualification: A member who has defected becomes disqualified for being a member of Parliament or State Legislature and cannot hold any office of profit under the government.

3. Time limits for disqualification: The disqualification comes into effect after the expiry of a period of one month from the date on which the defection takes place, to allow members to rectify their actions.

4. Anti-defection law exceptions: Members are not considered to have defected in certain cases, such as when they merge with another political party with the approval of two-thirds of their original party's members, or if a person is elected as Speaker or Chairman and resigns from his position without being affiliated with any political party.

5. Appointment of Presiding Officers: The President of India shall appoint a Speaker for the Lok Sabha and the Chairman for the Rajya Sabha, who will then decide on cases of defection based on the Tenth Schedule provisions.

6. Procedure for deciding disqualification: If a member is accused of defection, the Presiding Officer has to give them a chance to present their case before making a decision. The disqualified member can appeal to the President or Governor, whose decision will be final and cannot be challenged in any court.
