Michigan Compiled Laws, Chapter 600. Revised Judicature Act of 1961 § 600.550a

Sec. 550a. (1) Except as otherwise provided in this section, if a new judicial circuit is proposed by law, that new circuit is not created and any circuit judgeship proposed for the circuit is not authorized or filled by election unless each county in the proposed circuit, by resolution adopted by the county board of commissioners, approves the creation of the new circuit and each judgeship proposed for the circuit and unless the clerk of each county adopting that resolution files a copy of the resolution with the state court administrator not later than 4 p.m. of the sixteenth Tuesday preceding the August primary immediately following the effective date of the amendatory act permitting the creation of the new circuit. The state court administrator shall immediately notify the elections division of the department of state with respect to each new judicial circuit and circuit judgeship authorized under this subsection.

(2) By proposing a new judicial circuit and 1 or more circuit judgeships for the circuit, the legislature is not creating that circuit or any judgeship in the circuit. If a county, acting through its board of commissioners, approves the creation of a new circuit and 1 or more circuit judgeships proposed by law for that circuit, that approval constitutes an exercise of the county's option to provide a new activity or service or to increase the level of activity or service offered in the county beyond that required by existing law, as the elements of that option are defined by 1979 PA 101, MCL 21.231 to 21.244, and a voluntary acceptance by the county of all expenses and capital improvements that may result from the creation of the new circuit and each judgeship. However, the exercise of the option does not affect the state's obligation to pay a portion of the circuit judge's or judges' salary as provided by law, or to appropriate and disburse funds to the county for the necessary costs of state requirements established by a state law that takes effect on or after December 23, 1978.

(3) Each circuit judgeship created under subsection (1) must be filled by election under the Michigan election law, 1954 PA 116, MCL 168.1 to 168.992. The first term of each circuit judgeship is 6 years, unless the law permitting the creation of the new circuit and 1 or more judgeships provides for a term of a different length.

(4) The reformation of the eleventh, twenty-third, twenty-sixth, thirty-fourth, fiftieth, and fifty-third judicial circuits under 2002 PA 92  1 does not require a resolution of approval by the county board of commissioners under this section or section 550.  2

(5) The reformation of the twenty-seventh and fifty-first judicial circuits under the amendatory act that added this subsection  3 does not require a resolution of approval by the county board of commissioners under this section or section 550.
