Constitution of India · Part VI: The States · Conduct of Business
Article 189: Voting in Houses, power of Houses to act notwithstanding vacancies and quorum
In plain words
Unless the Constitution provides otherwise, questions in a House of a State Legislature are decided by a majority of members present and voting. The Speaker or Chairman does not vote at first, but has a casting vote in a tie.
- A House can act despite vacancies, and proceedings are valid even if someone not entitled later turns out to have taken part.
- Until the State Legislature provides otherwise, the quorum is ten members or one-tenth of the total members, whichever is greater. Without a quorum, the presiding officer must adjourn or suspend the meeting.
