As Assistant Solicitor General, Ryan successfully defended Texas A&M University in state and federal appeals related to the tragic “Aggie Bonfire” collapse, the State of Texas in a constitutional challenge to the Texas Civil Commitment of Sexually Violent Predators Act, and a court of appeals sued by a sitting appellate justice over opinion authorship.
