Before joining MSSSV, David was a partner at a prominent Long Island law firm. His practice focuses on advising, supporting and defending the insurance industry. It has included representing insurers in large, complex insurance coverage litigation in trial and appellate courts throughout the United States.

The coverage issues in those suits arose out of a variety of underlying liabilities. Many were “long tail” environmental or toxic tort claims that involved activities spanning years, if not decades, and potential exposures in the tens of millions of dollars. Others arose out of products liability, general liability, construction defect, and intellectual property disputes.

Some of the coverage issues David has litigated include the extent of an insurer’s defense obligation, the definition of “suit,” whether an underlying claim presented a claim for “damages,” allocation of liability amongst co-insurers, the applicable trigger of coverage, whether “property damage” or “bodily injury” exists, the application of policy exclusions, whether an occurrence is present, the timing and number of occurrences, determining the applicable limits of liability, and the exhaustion of underlying coverage or self-insured retentions.

In addition to defending insurers in litigation, David has provided insurers with opinions on a variety of coverage issues, as well as advice on claim management, dispute resolution strategy, and assessment of claim exposure.

Some of the notable insurance coverage cases David has litigated include:

NL Indus., Inc. v. OneBeacon Ins. Co., No. 108881-2009 (May 1, 2012, Sup. Ct. N.Y. Co.) (Bench Ruling) (Defeated claim that public relations and lobbying costs constitute reimbursable defense costs under a liability policy.)

Certain Underwriters at Lloyd’s, London v. Millennium Holdings, LLC52 A.D. 3d 295 (1st Dep’t 2008) (Obtained injunction preventing insured from prosecuting parallel litigation in Texas.)

Puget Sound Energy v. Certain Underwriters at Lloyd’s, London, 134 Wn. App. 228 (2006), rev. denied, 160 Wn. 2d 1022 (2007) (Successfully argued that trial court had the equitable power to bar contribution claims against an insurer that had settled with a common insured.)
