About anti-defection law:

  • The anti-defection law was added to the Constitution as the Tenth Schedule by the 52nd amendment in 1985.
  • The anti-defection law sought to prevent political defections which may be due to reward of office or other similar considerations.
  • It lays down the process by which legislators may be disqualified on grounds of defection by the Presiding Officer of a legislature, based on a petition by any other member of the House.


Conditions of disqualification under the anti-defection law :

  • Political Party members
    • If he either voluntarily gives up the membership of his party or
    • Disobeys the directives of the party leadership on a vote
  • Independent Members
    • If he / she joined a political party
  • Nominated Members
    • Nominated members who were not members of a party could choose to join a party within six months; after that period, they were treated as a party member or independent member, as the case might be.



  • The anti-defection law makes it mandatory that at least two-thirds of the strength of a party should agree for a ‘merger’ with another political party without getting disqualified under the anti-defection law.
  • There will be no disqualification if a person is elected as speaker or chairman, and he resigns from his party.


Deciding authority:

  • The Chairman or the Speaker of the House takes the decision to disqualify a member. However, if the complaint is against the defection of the Chairman or Speaker, a member of the House elected by that House shall take the decision.

Note: The law does not specify a time-period for the Presiding Officer to decide on a disqualification plea.
