The Circuit Court is a trial court of general jurisdiction established by the Michigan Constitution of 1908.  At one time the Circuit consisted of Eaton, Barry and Calhoun Counties and later Barry and Eaton Counties.  In 1991, the Circuit Court was split and Eaton County became a separate circuit, the 56th Circuit Court.
