Donskoy's petition challenged the rule for deciding whether claims share the same underlying facts, the timing of the Ninth Circuit's summary decision, and its treatment of his appeal as insubstantial.
Question presented
1. Whether the legal test examining the transactional nucleus of facts shared between causes of action, which evolved as common law of “res judicata doctrine” for the purpose of estoppel, is unconstitutional. 2. Whether the court of appeals may not take for review on the merits and grant a motion for summary disposition at “any time” during prolonged extension of time given for filing the answering brief. 3. Whether the court of appeals erred in affirming, based on “insubstantial appeal” standard, the district court dismissal of the Petitioner’s complaint.
