Current Role
  • Partner, Hagens Berman Sobol Shapiro LLP
  • Practice focuses on consumer, insurance, and antitrust class actions as well as appellate representation
Recent Success
  • In 2023, Mr. DeStefano argued and the Hagens Berman Arizona team prevailed before the Arizona Supreme Court in Franklin v. CSAA Insurance, obtaining a unanimous decision in Plaintiffs’ favor confirming that people injured by underinsured motorists in Arizona have the right to add together (or “stack”) insurance coverages for multiple vehicles under a single insurance policy. Mr. DeStefano and the Hagens Berman team are now working to recover additional insurance benefits for Arizona residents — many of them seriously injured — who were underpaid by thousands of dollars due to their insurers’ erroneous view of the law before Franklin.
  • When Continental Casualty Co. decided to seek and impose massive premium hikes on its long-term-care insurance customers, Hagens Berman filed suit to stop them and correct the abuse. The federal court initially granted Continental’s motion to dismiss, but Mr. DeStefano obtained a published reversal of that ruling from the U.S. Court of Appeals for the Seventh Circuit in 2020. After the case was remanded, he defeated three additional motions to dismiss in similar cases against Continental Casualty and discovery is ongoing.
  • Mr. DeStefano has also been active in litigation challenging insurers’ deliberate underpayments of total loss auto claims—unfair practices that short consumers after serious car accidents when they are often injured and at their most vulnerable. In early 2022, the U.S. District Court for the District of New Jersey granted Mr. DeStefano’s motion to certify a class of New Jersey consumers challenging GEICO’s use of improper adjustments to lower payments and its failure to pay substantial taxes and fees owed.
  • Mr. DeStefano also helped represent NFL legend Jim Brown in the appeal of his right-of-publicity suit against Electronic Arts for the unauthorized use of his likeness in Madden NFL video games. Shortly after briefing, Electronic Arts agreed to a $600,000 judgment in favor of Brown.
  • Mr. DeStefano was part of the Hagens Berman team that obtained court approval of $400 million settlement to compensate Hyundai and Kia owners for misstatement of EPA fuel economy ratings and successfully defended the settlement before the U.S. Court of Appeals for the Ninth Circuit, sitting en banc. Settlement payments averaged $353 for Hyundai owners and $667 for Kia owners.
