When CEQA Litigation Becomes “One Battle After Another”: First District Holds Res Judicata Precludes Third CEQA Action Challenging Caltrans’ Richardson Grove State Park Highway Improvement Project Where Petitioners Sought to Relitigate Issues Necessarily Resolved By Unappealed Final Orders Discharging Two Earlier Writs

April 13, 2026

In an important published opinion filed March 26, 2026, the First District Court of Appeal (Div. 2) affirmed a trial court’s judgment denying the third CEQA writ petition filed over the last fifteen years challenging Caltrans’ EIR for a project to improve a one-mile stretch of U.S. Highway 101 running through Richardson Grove State Park in Humboldt County. At issue in each action filed in the serial CEQA litigations – which the Court described as a “labyrinthine” “15-year litigation odyssey” – was the legal adequacy of the EIR’s analysis of the project’s impacts on adjacent old-growth redwood trees and their root systems. Bess Bair et al. v. California Department of Transportation et al. (2026) 119 Cal.App.5th 579. After an extensive procedural and legal analysis, the Court held the last petition was properly denied on res judicata grounds following the trial court’s discharge of peremptory writs in the two earlier actions by final orders that were never appealed.
