Can a father appeal against a juvenile court's finding that his son committed a sexual assault against his mother?

Under these circumstances, the issues Father's appeal raises are " 'abstract or academic questions of law' " (Epstein v. Superior Court (2011) 193 Cal.App.4th 1405, 1408), since we cannot render any relief to Father that would have a practical, tangible impact on his position in the dependency proceeding. Even if we found no adequate evidentiary support for the juvenile court's findings with respect to his conduct, we would not reverse the court's jurisdictional and dispositional orders nor vacate the court's assertion of personal jurisdiction over his parental rights.
