In Woodland Joint Unified School Dist. v. Commission on Professional Competence (1992) 2 Cal.App.4th 1429, the appellant claimed that his due process rights were violated when material in private files was admitted before the commission. The appellate court concluded that the appellant "waived this contention by failing to object to the material on this ground either before the Commission or in the trial court." ( Id. at p. 1449.) Woodland Joint USD involved waiver of an evidentiary objection; it does not hold that a terminated employee waives a Skelly objection by failing to assert it in a postdeprivation administrative hearing.
