(September 8, 2015, 12:01 PM EDT) -- BOSTON — The First Circuit U.S. Court of Appeals on Sept. 4 affirmed a finding that an insurer has a duty to defend an insured in an environmental contamination coverage dispute and said the district court applied the correct allocation method but that because the record does not support the insured’s claim for unfair or deceptive business practices, that portion of the district court’s ruling must be vacated (Peabody Essex Museum Inc. v. United States Fire Insurance Co., No. 13-1528, 13-1602, 1st Cir.; 2015 U.S. App. LEXIS 15858)....
