Constitution of the State of Michigan

1963

Michigan adopted its current constitution in 1963, replacing a document that dated to 1908. The revision came after decades of population growth and industrial transformation that had strained the old framework, and it modernized state government by strengthening civil rights protections, reorganizing the executive branch, and creating a non-partisan supreme court. It was the product of a constitutional convention that drew delegates from across the state and across party lines. Michigan has since amended it on numerous occasions, most significantly through voter-initiated ballot measures.
