Legal Definitions - proportional quorum

Definition: Proportional quorum is a type of quorum that is calculated based on a defined or assumed set, usually either the number of seats (including vacancies) or the number of sitting members (excluding vacancies). It is used to determine the minimum number of members required to be present for a deliberative assembly to legally transact business.

• If a board of directors has 10 members and a proportional quorum is set at 60%, then at least 6 members must be present for the board to conduct business.
• In a parliament with 100 seats, a proportional quorum of 50% would require at least 51 members to be present for the parliament to conduct business.

These examples illustrate how proportional quorum is calculated based on a defined or assumed set, and how it is used to determine the minimum number of members required for a deliberative assembly to legally transact business.
