ORDERED that the order is reversed insofar as appealed from, on the law, the motion is granted, and the matter is remitted to the Supreme Court, Kings County, for the entry of a judgment declaring that the defendant is obligated to defend and, if necessary, indemnify the plaintiff and reimburse the plaintiff for all past defense costs in the underlying personal injury action; and it is further,
ORDERED that the order is affirmed insofar as cross-appealed from; and it is further,
ORDERED that the plaintiff is awarded by one bill of costs.
The plaintiff, the City of New York (hereinafter the City), as an additional insured of the defendant, Northern Insurance Company of New York (hereinafter Northern), made a claim under the insurance policy at issue. The City's notice showed that it was aware of the occurrence for over 16 months before notifying Northern, and the City offered no excuse for the failure to notify Northern earlier. As a result, Northern disclaimed coverage.
However, Northern's two-month delay in disclaiming coverage was unreasonable as a matter of law, as the ground for the disclaimer was obvious on the face of the City's notice of claim. Northern's attempt to justify its delay in disclaiming coverage on the ground that it had to investigate whether the City was an additional insured is, in this instance, an insufficient excuse as a matter of law, as such an investigation was unrelated to the reason for the disclaimer and could have been asserted at any time. Thus, the City should have been granted summary judgment (see, Mount Vernon Fire Ins. Co. v. Gatesington Equities, 204 A.D.2d 419; cf., 2540 Assocs. v. Assicurazioni Generali, 271 A.D.2d 282; see also, Zappone v. Home Ins. Co., 55 N.Y.2d 131).
Since this is an action for a declaratory judgment, the matter is remitted for the entry of a judgment declaring that Northern is obligated to defend and, if necessary, indemnify the City and to reimburse it for all past defense costs in the underlying personal injury action (see, Lanza v. Wagner, 11 N.Y.2d 317, 334, appeal dismissed 371 U.S. 74, cert denied 371 U.S. 901).
The parties' remaining contentions are either without merit or need not be reached in light of this determination.
