He shall transact all necessary business with the officers of government and may require information in writing from all executive and administrative state officers, elective and appointive, upon any subject relating to the duties of their respective offices.
The governor may initiate court proceedings in the name of the state to enforce compliance with any constitutional or legislative mandate, or to restrain violations of any constitutional or legislative power, duty or right by any officer, department or agency of the state or any of its political subdivisions.
