O'Sullivan v. Haught

Summary

The court held that the denial of summary judgment based on a colorable collateral-estoppel claim was immediately appealable, so the Appellate Court improperly dismissed the defendant's appeal. Exercising supervisory authority, the court held that the pending de novo probate appeal suspended the preclusive effect of the Probate Court decree, although the trial court reached that result for the wrong reason. The judgment was reversed and remanded with directions to affirm the denial of summary judgment on the tortious-interference claim and order further proceedings.
