The appropriate governing body of a public employer is the policymaking individual or body representing the public employer. In the case of the state, the appropriate governing body is the governor or his designee or, in the case of a constitutionally created body, the constitutionally designated head of that body. At the local level, the appropriate governing body is the elected or appointed representative body or individual charged with management of the local public body. In the event of dispute, the board shall determine the appropriate governing body.
