BOSTON - An insurer has no duty to provide coverage beyond $5,000 for property damage caused by an oil spill because the policy's pollution exclusion bars additional coverage, the Massachusetts Appeals Court said July 2 (Frank Izdebski v. Hanover Insurance Group Inc., Nos. 12-P-1950, 12-P-1951, Mass. App.; 2014 Mass. App. Unpub. LEXIS 814).
