Majority voting rule: legislative questions decided by members present and voting, with speaker exercising a casting vote on ties. Questions at sittings of a State Legislature are determined by a majority of votes of members present and voting, excluding the Speaker or Chairman in the first instance, who has a casting vote in the case of equality. A House may act notwithstanding vacancies and its proceedings remain valid despite subsequent discovery that an ineligible person took part. Until the Legislature provides otherwise, the Constitution prescribes a quorum rule and the Speaker or Chairman must adjourn or suspend meetings when no quorum is present.
