Greg Deschenes has over 30 years’ experience handling complex commercial litigation, with an emphasis on all aspects of insurance-related litigation. Representing major insurance companies and insurance guaranty funds in state and federal courts across the country, Greg has prevailed at trial and the appellate level in cases involving property and casualty insurance coverage, bad faith, insurance insolvency and class actions.
For more than three decades I’ve litigated insurance coverage disputes involving environmental and toxic tort, construction defect, catastrophic losses, advertising injury and personal injury, directors’ and officers’ liability, business interruption, life and disability insurance claims.
I represent a number of insurance guaranty funds in coverage litigation and disputes with receivers of insolvent insurers.
I’ve defended insurers against a variety of bad faith lawsuits, including both first-party insurance and third-party bad faith claims. In New England, I’ve acted as regional counsel for a Fortune 200 property and casualty insurance company in the defense of major environmental insurance coverage and bad faith/extra-contractual liability lawsuits.
I have significant experience defending products liability, environmental, securities fraud and complex business litigation cases.
I also have extensive appellate experience and have successfully represented clients in cases before the First Circuit Court of Appeals, the Massachusetts Supreme Judicial Court, the Connecticut Supreme Court, the Maine Supreme Judicial Court, the New Hampshire Supreme Court and the Rhode Island Supreme Court.
The insurance industry faces a number of challenges managing emerging risks posed by new technologies such as data security breaches and cyberattacks, AI and driverless vehicles, climate change and pandemics, and other catastrophic events.
Greg has participated as a faculty member in many continuing legal education programs and has published numerous articles on litigation and insurance topics, including the following:
This article covering a summary judgment in favor of client Westchester Surplus Lines Insurance Co. mentions Boston partner Greg Deschenes and Manchester associate Nate Warecki, both of the Complex Disputes group, for representing the insurer. A federal judge ruled the insurer is not responsible for covering an apartment complex owner for a lawsuit filed by the family of a child bitten by a dog at the complex, because an animal exclusion in a commercial general liability policy precludes insurance for the incident.
