A minimum number of members or directors required to be present at a meeting before the body may validly transact business. The requirement ensures that decisions reflect sufficient participation and prevents a small subset from binding the larger group. Governing documents or statutes may raise or lower the default but often impose a floor such as one third of the fixed number of directors.

Shareholder Consent Action
