To “break quorum” means there are not enough members present (or participating) for a group to legally conduct official business or take valid votes, according to that group’s rules or laws.

Quick meaning

  • A quorum is the minimum number of members who must be present for a meeting, board, council, or legislature to act.
  • Breaking quorum happens when attendance drops below that minimum, either because too few people show up or because some members leave during the meeting.
  • Once quorum is broken, most bodies can’t validly vote, pass motions, or do other official business until enough members are back.

How it works in practice

  • Many organizations define quorum in their bylaws (for example, a simple majority, two‑thirds, or another fraction of all members).
  • If a board has 10 members and its quorum is 6, then having only 5 present means quorum is broken and the board usually must adjourn, recess, or only take limited procedural steps (like trying to summon absent members).
  • In some legislatures (like the Texas House in 2021), members from one party have left the chamber or even the state specifically to break quorum and stop a bill from being passed; this is often called “quorum‑busting” or a “walkout.”

Why people break quorum on purpose

  • It can be used as a tactic by a minority that lacks the votes to win normally, but can still prevent the majority from meeting the quorum needed to act.
  • By denying quorum, that minority can delay or block votes on controversial measures, force negotiations, or draw public attention to an issue.
  • Because this can paralyze a body, many rulebooks include ways to discourage or punish intentional quorum‑breaking, such as compelling attendance or imposing penalties.

Key takeaways

  • “Quorum” = minimum number needed to do real business.
  • “Breaking quorum” = falling below that number, so the body is effectively blocked from acting.
  • It can be accidental (low attendance) or deliberate (a walkout to block action), but either way, decisions taken without quorum are usually not valid.
