I have a civ pro question that seems so basic but is giving me a hard time.
Here are the facts:
(1) Man gets fired, files a grievance for wrongful termination, grievance is denied in a quasi-judicial proceeding with hearings, presentation of evidence, witnesses, etc etc
(2) Man petitions for writ of mandate in trial court, which is denied.
(3) Man appeals denial, appellate court affirms
If one wanted to collaterally estop man from relitigating an issue previously decided in Round 1, would one look to the findings in the quasi-judicial grievance proceeding, the trial court order, the appellate court decision, or some combination of all three?
