It sets the provisions for disqualification of elected members on the grounds of defection to another political party.
The anti-defection law punishes individual Members of Parliament (MPs)/MLAs for leaving one party for another.
It allows a group of MP/MLAs to join (i.e., merge with) another political party without inviting the penalty for defection.
As per the 1985 Act, a 'defection' by one-third of the elected members of a political party was considered a 'merger'.
