Michigan Compiled Laws, Chapter 600. Revised Judicature Act of 1961 § 600.9924

Sec. 9924. (1) All files, records, funds, and pending cases of the courts abolished under section 9921  1 or courts or divisions of courts abolished on or after April 1, 1973, and succeeded by the district court shall be transferred to the district court of the district in which the courts have served, in accordance with rules prescribed by the supreme court, and the district court shall exercise all powers in regard thereto as provided by rules of the supreme court. The district court shall have jurisdiction to hear and determine all cases transferred under this section, and shall exercise all authority with regard to those cases as though the cases had been commenced in district court. All orders and judgments of courts or divisions of courts abolished on or after May 1, 1981, and succeeded by the district court shall be appealable in like manner and to the same courts as applicable before that date. This subsection shall not apply to files, records, funds, and pending cases of the traffic and ordinance division of the recorder's court which are transferred to the recorder's court pursuant to section 38 of Act No. 369 of the Public Acts of 1919, being section 725.38 of the Michigan Compiled Laws.

(2) When 2 or more district court districts are reconstituted into a single district, all files, records, funds, property, and pending cases of the district court of the abolished districts shall be transferred to the district court of the reconstituted district. The district court of the reconstituted district shall exercise all powers with regard to transferred files, records, funds, property, and cases as the district courts of the abolished districts could have exercised before the reconstitution. The district court of the reconstituted district shall have jurisdiction to hear and determine all cases transferred to it from the district courts of the abolished districts.

(3) When 2 or more district court districts are reconstituted into a single district, each incumbent district judge of the abolished district or reconstituted district shall serve as a district judge of the reconstituted district until the expiration of the term for which he or she was elected or appointed and shall be considered an incumbent district judge of the reconstituted district for all purposes for the balance of that term.
