Choice of law in SUM context – interesting

By Jason Tenenbaum 8 min read

Key Takeaway

NY Court of Appeals applies Massachusetts law to SUM claim despite NY policy and NY victim, prioritizing accident location over policy terms in complex choice of law analysis.

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.

Jason Tenenbaum’s Analysis:

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 [*2]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.
