Michigan has a republican form of government with three branches of government: the executive branch consisting of the Governor of Michigan and the other independently elected constitutional officers; the legislative branch consisting of the House of Representatives and Senate; and the judicial branch consisting of the one court of justice. The state also allows direct participation of the electorate by initiative, referendum, recall, and ratification.
