Maryland Cas. Co. v. NSTAR Elec. Co.Annotate this Case
When a fire caused by NSTAR Electric and Gas Company employees damaged a building owned by the Massachusetts Institute of Technology (MIT), two insurers paid the claims of the building’s tenants. The insurers then brought this complaint against NSTAR Electric Company and NSTAR Electric & Gas Company (collectively, NSTAR) seeking to recover for the claims paid. NSTAR moved for partial summary judgment, contending that, to the extent to which the insurers sought recovery for business interruption losses, the claims were barred by Massachusetts Department of Telecommunications and Energy Tariff No. 200A, filed with and approved by the Department of Public Utilities, and in effect when the explosion occurred. The tariff contained a limitation of liability clause that limited NSTAR from liability to nonresidential customers for special, indirect, or consequential damages resulting from the utility’s gross negligence. A judge of the superior court allowed NSTAR’s motion for partial summary judgment, concluding that a tariff filed with and approved by a regulatory agency may limit a public utility’s liability. The Supreme Judicial Court affirmed, holding that the limitation of liability clause in the tariff precluded Plaintiffs’ claims to recover for business interruption and other consequential or economic damages.
