The Nineteenth Constitutional Amendment Act, 1966 abolished the system of Election Tribunals in India. Prior to this amendment, disputes concerning the elections of Members of Parliament and State Legislatures were handled by these tribunals.

After their abolition, the authority to resolve such election disputes was transferred to the High Courts under the Representation of the People Act, 1951. This shift aimed to make the dispute resolution process more efficient and authoritative. The amendment came into force on 11 December 1966.
