During legislative sessions, the Legislature is called upon to: enact or reject legislation affecting public policy in the state; provide for the levy and collection of taxes and other revenue to support state government and assist local government; and appropriate funds for these purposes. The Senate also has the exclusive power to confirm certain gubernatorial appointments. Although laws are enacted only when the Legislature is convened in formal session, policy issues and the general operation of state and local government are under continuous review by legislators serving on permanent and interim study committees.
