Representative Matters

(2017-ongoing): This breach of contract claim turned on environmental issues including new regulations of the discharge of treated wastewater by a regional wastewater treatment facility located in Riverside California. A bench trial was held in 2017-2018. Ring Bender (Patrick “Kit” Bobko, Norm Dupont and Jay Tufano) then completed appellate briefing in April 2023. The case is now waiting for oral argument and a decision before California’s Fourth Appellate District, Division 3.
  • Bradford v. City of Compton (2016-2022):Jury trial with a defense verdict in favor of municipal defendant on labor discrimination/retaliation claims. After remand from the Court of Appeal, a second trial resulted in verdict for plaintiff. In October 2021, the Court of Appeal reversed the jury verdict and thereby remanded the case for further proceedings.  In January 2022, the California Supreme Court denied Plaintiff’s petition for review. In June 2022, the California Court of Appeal granted a summary reversal of an award of attorneys’ fees to plaintiff’s lawyers in the second trial.
