If you wish to argue a Procedural Due Process violation, you do just that, it does not fall under 1983, nor as a EP claim. A 1983 complaint is just that, a Complaint for damages and or Declaratory/Injunctive relief.
If a Judge violates DP, then on appeal argue that. An Appeal is not a legal injury, it is asking a higher court to review a case on any alledged assignment of error, here, violation of DP.
Since you said MI small claims are not subject to appeal, the most you can do is write the judge/referee with your statement of opposition.
