Michigan Compiled Laws, Chapter 400. Social Services § 400.59d

Sec. 59d. The decision of the director may be in favor of either of the contending counties or that domicile lies in neither of the counties or that settlement does not lie in this state or that there is insufficient evidence on which to make a finding of settlement. The decision of the director shall be final. If the decision is that there is insufficient evidence for a determination, all the proceedings of both counties shall be set aside and the county granting relief may proceed anew as if no notice had been sent under sections 59a and 59b.  1
