Am. Ins. Co. v. Siena Constr. Co., 2007 WL 4711517 (Mass. Super. Ct. Dec. 24, 2007)
In this case, the Superior Court considered two consolidated cases that both arose out of an explosion of a newly constructed building. In both cases the plaintiffs were insurance companies acting as subrogees. Defendants (general contractors and subcontractors) moved for summary judgment on the ground that recovery was barred by “Waiver of Subrogation” clauses found in the contracts. The plaintiffs argued that the waiver of subrogation clause did not extend to damages caused by a defendant’s gross negligence or its violation of a statute or regulation. In addition, they argued that the subcontractors were not protected by the waiver of subrogation clause.
The original judge in the case held that analogous case law concerning exculpatory clauses supported a denial of defendants’ summary judgment motion. The judge also held that, by its terms, the waiver of subrogation clause did not include subcontractors. In the consolidated case, the new judge accepted the rulings of prior judge and the motions for summary judgment were allowed in part and denied in part. Plaintiffs’ claims were allowed to proceed but as to defendants with valid waiver of subrogation clauses (contractors not subcontractors) recovery was limited to damages arising from defendant’s gross negligence, or negligence premised on a violation of statute or regulation.
