If any single political party or political parties alliance wins the majority seats in the Assembly the leader of that political party or alliance will become as the Chief Minister of the state. Even though any party or alliance haven't won the majority seats then Governor invites the leader of the most seats won party or alliance to form the government but the party have to prove its majority in the house in short period of the time.
