MI HB5124

Establishes procedures for adopting concurrent jurisdiction plans allowing circuit, probate, and district courts to exercise each other's powers and jurisdiction, subject to supreme court approval and limitations.

Applies different concurrent jurisdiction frameworks to three categories of counties: general judicial circuits (section 401), large counties with third-class district courts (sections 406-408), and specific large counties including Genesee, Ingham, Kent, Macomb, Oakland, Washtenaw, and Wayne.

Prohibits concurrent jurisdiction plans from delegating powers of appointment to public offices as established by constitution or statute.

Requires concurrent jurisdiction plans to prioritize benefits to citizens rather than courts or judges, and establishes procedures for judges to file objections with the state court administrator based on resource allocation, training, or other concerns.

Takes effect January 1, 2013, and grandfathers concurrent jurisdiction plans that were adopted and approved before that date as valid under the new framework.
