How Blonder-Tongue Laboratories, Inc. v. University of Illinois Foundation applies in Michigan: state-specific rules, key cases, and bar exam notes for Civil Procedure (Collateral Estoppel/Issue Preclusion) and Patent Law.
In Michigan, the principles of collateral estoppel or issue preclusion enable a party to prevent the relitigation of an issue that was previously resolved in a final judgment. Michigan courts recognize the necessity of mutuality and substantial equivalent of parties involved in the prior and present cases for the application of collateral estoppel.
Under Michigan law, collateral estoppel applies when: (1) the same issue was actually litigated and determined in a prior proceeding; (2) the prior proceeding resulted in a valid final judgment; (3) the parties or their privies had sufficient identity in the prior case; and (4) it would not be unfair to apply preclusion.
The court held that collateral estoppel applies even where the parties are not in privity, as long as the issues were fully and fairly litigated.
The court enforced issue preclusion, ruling that a determination made in a lawsuit related to a teacher's conduct was binding in a subsequent wrongful termination claim.
The court ruled that a criminal defendant could not relitigate an issue once the jury had reached a verdict in a previous trial.
Michigan's approach to collateral estoppel is similar to the federal standard, which also requires the same issue to have been previously adjudicated. However, Michigan requires an explicit identity of parties or their privies, whereas the federal standard may more broadly consider legal interests in its application.
Candidates should be familiar with the Michigan standards regarding collateral estoppel, particularly regarding its application in patent law cases and how prior rulings may affect subsequent patent litigation.
