Collegial body
Collegial body (or collegiate body, collegial executive, collective executive) is a governmental or organizational entity in which power and authority are vested equally in each of a number of colleagues, rather than in a single individual. This structure is typically contrasted with monocratic authority (bureaucracy), where power is held by a single chief or executive and flows through a hierarchy.
In sociology and political science, collegiality is analyzed both as a historical mechanism for limiting arbitrary power and as a modern structural adaptation in organizations dominated by professionals.
