What Is a Quorum and Why Does It Matter?
Before a meeting is called to order, someone may ask the question: do we have enough people here to proceed? Getting it wrong can cause actions to become invalid later if there is clear proof that no quorum was present when the business was transacted.
The Basic Definition
A quorum is the minimum number of members that must be present for a deliberative body to conduct business. Action taken without a quorum—a motion passed, or an officer elected—may later be ruled null and void.
The rule exists to protect the membership as a whole. Without it, a small group of people could show up to a thinly attended meeting and bind the entire organization to decisions the broader membership never had a chance to weigh in on.
The Default Under Robert's Rules
Robert's Rules of Order, Newly Revised (RONR) sets a default quorum of a majority of the entire membership when an organization's bylaws are silent on the matter. A majority simply means more than half. (If an organization has 9 members, a majority is five. For this reason, it is wise to be careful with percentages; if the quorum was defined as 50%, what would it be in this case?) For most associations, a majority is unworkably high. A membership of 500 would need 251 people in the room.
That is why the default rarely applies in practice. Most organizations set their own quorum in the bylaws at something more realistic. For boards of directors specifically, RONR defaults to a majority of the board when the bylaws say nothing.
Setting the Right Threshold
There is no universal formula. The right quorum depends on your membership size, your typical meeting attendance, and what kind of decisions your body makes. Some organizations use a fixed number; others use a percentage. Boards usually go with a majority of board members.
Set it high enough to be meaningful and low enough to be achievable. A quorum requirement that routinely cannot be met causes governance problems, since the organization ends up unable to conduct business. RONR 40:3 states: "The quorum should be as large a number of members as can reasonably be depended on to be present at any meeting, except in very bad weather or other exceptionally unfavorable conditions."
What to Do When Quorum Is Not Present
If you cannot achieve quorum, the meeting cannot proceed to business. The presiding officer should say so promptly. Four things remain permissible without a quorum, humorously memorized by parliamentarians with the acronym FART:
• Fix the time to which to adjourn
• Adjourn
• Recess
• Take steps to contact and bring in absent members
Proceeding anyway, or simply not bothering to check, creates real exposure. Decisions made without quorum can be challenged and unwound, sometimes with legal and financial consequences.
Quorum Can Be Lost Mid-Meeting
Checking quorum at the start of a meeting is not enough. If members leave and quorum drops below the required threshold, business cannot proceed. Any member can raise a point of order to alert the assembly that quorum may have been lost.
This happens more often than it should. Members leave during a long meeting, the remaining group keeps going, and nobody notices until someone raises the issue afterward. Keeping an eye on attendance throughout is a basic responsibility of the chair and the secretary.
A Few Practical Notes
Your bylaws should state the quorum requirement explicitly. Use a sign-in sheet or attendance record at every meeting so you have documentation. And if your bylaws have quorum language in more than one place, check that the provisions are consistent.
If your governing documents are silent on quorum or the language is ambiguous, that is worth fixing. A parliamentarian can help you draft language that fits your organization and holds up under scrutiny.
