Representative Matters

  • Helped coordinate the nationwide defense of a firm client against waves of litigation, including securing defense verdicts in several state court matters, removing numerous other matters to federal court, and then successfully coordinating those matters through the United States Judicial Panel on Multidistrict Litigation, before ultimately reaching a favorable global resolution.
  • Member of the trial team in a significant arbitration in New York City that resulted in a substantial recovery for a firm client in an overpayment recovery action.
  • Member of the trial and appellate team that secured summary judgment in favor of a firm client, who had been sued in successive lawsuits in state court. Colin convinced the trial court that the second action ― though different in kind ― was barred by res judicata and/or collateral estoppel. Colin then successfully argued before the Pennsylvania Superior Court to have the victory affirmed on appeal.
  • Member of the trial and appellate team that secured summary judgment in favor of firm clients, who had been accused by the widow of a former National Hockey League player of failing to pay insurance benefits that the companies maintained were never purchased. The Superior Court affirmed the trial court’s decision.
  • Member of the trial and appellate team that secured a $7 million jury verdict in favor of landowners, whose property had been taken to create a municipal golf course. The jury verdict was appealed to the Commonwealth Court and the Supreme Court, which both affirmed it. The case resulted in new precedent in Eminent Domain matters that now allows “bona fide” offers to purchase land to be considered by a jury in valuing land taken by the government.
