If no single party or pre-poll alliance gets a clear majority in any state election, it is called a hung assembly. This may lead to the formation of a coalition government in which parties enter into post-poll alliances. It may even lead to formation of a government with outside support of parties and independent MLAs.
In case no government can be formed, then re-election may take place or President’s Rule could be imposed by the state governor under Article 356 of the Constitution.
