Mich. Comp. Laws § 105.17: Circuit court; jurisdiction; proceedings.

Sec. 17.

Upon filing the return to the probate court, as mentioned in the preceding section, the circuit court shall have jurisdiction of the case. The parties may proceed to trial by jury without reference to any term of court upon the question as to the amount of damages to be awarded; but the finding of the jury before the probate court as to the necessity of taking the land shall be held to be conclusive. The appeal of 1 or more persons interested in any judgment of confirmation shall not in any way affect said judgment as to other persons interested therein who do not appeal.
