Article 100 of the Constitution deals with voting in Houses of Parliament, their power to act despite vacancies and the quorum required for a meeting. The quorum is one-tenth of the total number of members of the House.
What quorum means
A quorum is the minimum number of members who must be present for a House to transact business. Article 100 states that, until Parliament provides otherwise by law, the quorum for a meeting of either House is one-tenth of the total number of members of the House.
Quorum is not the same as a majority
A quorum establishes the minimum presence needed for business; it is not the number required to pass every motion. Voting outcomes depend on the relevant constitutional or procedural rule. Questions may mix up quorum, simple majority, special majority and total strength, so identify which concept is being asked.
How to remember the article
Use Article 100 for voting and quorum in Parliament. Read the exact constitutional text for the phrase one-tenth of total membership. If a question supplies a House strength, calculate one-tenth only after confirming what total the question uses.
