The Ninth Circuit certified a question to the Washington Supreme Court as follows:
Under Washington law, is an insurer bound by representations made by its authorized agent in a certificate of insurance with respect to a party's status as an additional insured under a policy issued by the insurer, when the certificate includes language disclaiming its authority and ability to expand coverage?
T-Mobile USA Inc. v. Selective Ins. Co lf Am., 2018 U.S. App. LEXIS 31863 (9th Cir. Nov. 9, 2018).
In 2010, T-Mobile entered into a Field Services Agreement (FSA) with Innovative Engineering, Inc. under which Innovative would provide services in connection with the construction of rooftop cellular antennae towers in New York City. The FSA required Innovative to maintain general liability insurance naming T-Mobile as an additional insured, and required that Innovative provide T-Mobile with certificates of insurance documenting the coverage. Innovative obtained coverage from Selective Insurance Company of America.
