Choice of law issues in insurance cases often involve complex multi-jurisdictional scenarios where courts must determine which state’s laws should govern a claim. This becomes particularly intricate in Supplementary Uninsured/Underinsured Motorist (SUM) coverage cases, where the insurance policy, accident location, parties involved, and applicable damages may all be governed by different states’ laws.
The Fourth Department’s decision in Erie Insurance Co. v Boss presents a fascinating example of how New York courts approach these jurisdictional puzzles. When faced with competing interests between the state that issued the policy and the state where the accident occurred, courts must balance various policy considerations and legal principles to reach a fair outcome.
This case also highlights the ongoing evolution of choice of law doctrine in insurance contexts, which has seen significant development in recent years, particularly in no-fault insurance cases and complex multi-state scenarios.

Matter of Erie Ins. Co. v Boss, 2011 NY Slip Op 03758 (4th Dept. 2011)
(1) New York policy, (2) Massachusetts accident, (3) Massachusetts tort-feasor, and (4) New York victim.
What is the result? Massachusetts law.
“We thus conclude that an individual insured under a New York automobile policy who is injured in an accident in another jurisdiction should not be placed in either a better or worse position when filing a SUM benefits claim than he or she would have been if the tortfeasor had been fully insured. To apply New York law to the measure of damages in this case would not be consistent with the purpose served by SUM coverage, which is to take the place of a tortfeasor’s insufficient insurance coverage.”
Compare with recent New York no-fault choice of law cases.
Key Takeaway
The Fourth Department’s ruling demonstrates that in SUM coverage cases, courts prioritize the fundamental purpose of uninsured motorist coverage over the technical details of policy origin. By applying Massachusetts law despite the New York policy and New York victim, the court ensured the injured party received the same protection they would have had if the tortfeasor carried adequate insurance, maintaining the essential function of SUM coverage as a substitute for insufficient third-party insurance.

Legal Context
Why This Matters for Your Case
New York law is among the most complex and nuanced in the country, with distinct procedural rules, substantive doctrines, and court systems that differ significantly from other jurisdictions. The Civil Practice Law and Rules (CPLR) governs every stage of civil litigation, from service of process through trial and appeal. The Appellate Division, Appellate Term, and Court of Appeals create a rich and ever-evolving body of case law that practitioners must follow.
Attorney Jason Tenenbaum has practiced across these areas for over 24 years, writing more than 1,000 appellate briefs and publishing over 2,353 legal articles that attorneys and clients rely on for guidance. The analysis in this article reflects real courtroom experience — from motion practice in Civil Court and Supreme Court to oral arguments before the Appellate Division — and a deep understanding of how New York courts actually apply the law in practice.

New York law varies by jurisdiction — court decisions in one Appellate Division department may not be followed in another, and local court rules in Nassau County Supreme Court differ from those in Suffolk County Supreme Court, Kings County Civil Court, or Queens County Supreme Court. The Appellate Division, Second Department (which covers Long Island, Brooklyn, Queens, and Staten Island) and the Appellate Term (which hears appeals from lower courts) each have distinct procedural requirements and precedents that affect litigation strategy.
