Ron is a business trial lawyer, appellate lawyer and counselor. Ron advises financial institutions, insurers and reinsurers, technology companies, and other businesses in high-stakes litigation matters, particularly where taking the case through trial or appeal needs to be part of the client’s arsenal.

Ron and his trial teams have prepared to try and tried two to four cases a year in courts and before arbitration panels every year for more than a decade. He and his teams have also prepared and argued appeals in appellate courts around the country at the rate of several a year. Most of this work has been for an array of insurers and reinsurers in sophisticated coverage, bad faith, and reinsurance disputes. A substantial part of this practice includes representing insurers and reinsurers in business disputes against financial institutions, other large companies, and healthcare and managed care companies on E&O, D&O, professional liability, reinsurance, and ERISA coverage disputes. The firm’s practice extends to trial and appeals courts in more than 25 jurisdictions. These cases include disputes in the billions of dollars.

Representative Matters

  • USA Gymnastics v. Liberty Insurance Underwriters Inc. – USA Gymnastics has demanded coverage from our client Liberty Insurance Underwriters Inc. under a D&O liability policy issued to USAG beginning in May 2016. The alleged claims arise from (1) multiple cases pending in Michigan, Colorado, and California against USAG seeking damages for Dr. Larry Nassar’s sexual abuse of athletes while he was serving as USAG’s team physician, and (2) investigations initiated by, among others, both houses of Congress and the US Olympic Committee, investigating Nassar’s abuse and how it was able to proceed. Liberty denied coverage under its polices, among other reasons, based on exclusions of coverage of claims related to intentional acts and claims for bodily injury, lack of an insured claim for a wrongful act, and because claims pre-dated Liberty’s policy period. Ron argued the case before the US Court of Appeals for the Seventh Circuit on November 9, 2020. Listen to the argument here.
  • In Re Verizon Insurance Coverage Appeals – Represented excess insurer in Delaware Superior Court and Delaware Supreme Court, winning a reversal and judgement at Supreme Court, in $50 million D&O dispute concerning coverage for “Securities Claims.” Appeal also addressed whether trial court wrongly denied separate trial on allocation and reasonableness of defense costs and Delaware choice of law. Watch the argument here.
  • Millennium Laboratories, Inc. v. Allied World Assurance Company (U.S.) Inc. – Lead trial and appellate lawyer in successful defense against $5 million coverage demand in D&O coverage litigation. The Policyholder, sought coverage for costs Millennium incurred in defending against an investigation by the U.S. Department of Justice (the “DOJ Investigation”), which was commenced by the DOJ’s service of a document subpoena on Millennium.  The policy at issue contained an endorsement that defined “Claim” so as to include certain investigations commenced by service of a subpoena.  Our insurance coverage department represented Allied World at every stage of the coverage litigation, before the U.S. District Court for the Southern District of California and then the U.S. Court of Appeals for the Ninth Circuit, securing a defense judgment of no coverage.
  • Jacob Horn, et al. v. Liberty Insurance Underwriters, Inc. – Secured summary judgment for insurer in connection with coverage demand for $60 million consent judgment entered to resolve for alleged underlying violations of the TCPA.

Zurich contended that the insured never sought consent and never properly notified Zurich of the claim, which are both conditions precedent under the Zurich policy. In December 2016, we secured a defense verdict, removing Zurich’s $15 million policy from exposure. The Court denied post-trial motions in June 2017. TIAA-CREF appealed to the Delaware Supreme Court, seeking relief from the finding that it had never properly given Zurich notice of the settlement and potential claims and also urged the court to reverse the lower court’s denial of prejudgment interest. Ron argued the appeal for Zurich on June 6, 2018. Watch the full argument here.
  • Massachusetts Bay Ins. Co. v. American Healthcare Services Association, et al. – Lead trial and appellate attorney.  On March 1, 2017, Ron argued an appeal before the Supreme Court of New Hampshire in a case involving a multi-million dollar healthcare insurance dispute stemming from dozens of patients contracting Hepatitis C while being treated at a New Hampshire area hospital, which ultimately led to a criminal prosecution.  In September 2017, the Court ruled in favor of Ron’s client, Arch Insurance Company.
