Mealey's (March 31, 2017, 11:40 AM EDT) -- BROOKLYN, N.Y. — A New York appeals panel on March 15 held that a commercial general liability insurer is estopped from disclaiming coverage under a policy exclusion because it failed to provide an additional insured timely notice of its denial of coverage on the basis of the exclusion, partly reversing a lower court’s grant of summary judgment in favor of the insurer in a coverage dispute arising from a building collapse (Harco Construction, LLC, et al. v First Mercury Insurance Co., et al., [Index No. 16011/13] No. 2015-00839, N.Y. Sup., App. Div., 2nd Dept., 2017 N.Y. App. Div. LEXIS 1766)....
