Convention Law and Legal Definition

Convention refers to all kinds of agreements, compacts or treaties entered into by the nations, such as Geneva Convention. Convention is mostly used to denote a deliberative assembly which amends, revises or helps in framing a constitution of a state. Such a convention is termed constitutional convention.

In legislative law, the term convention is used to denote a deliberative assembly consisting of delegates elected for the purpose of policy making and purposes other than normal legislation. These delegates usually exercise the organization’s highest policymaking powers. Such delegates may be appointed from subordinate or constituent organizations within a state or national organization, or elected directly from the organization's membership or from defined geographic or other constituencies into which the membership is grouped. Such convention is termed assembly, delegate assembly, convocation or congress.
