Defendant New York City Economic Development Corporation (EDC) and plaintiffs Aquatic Development Group, Inc. (ADG) and Recreation Development, Inc. (RDI) are not signatories to the Waterpark Concession Agreement between plaintiff Randalls Island Aquatic Leisure, LLC (RIAL) and the City (through the Department of Parks and Recreation), which governs this dispute. Thus, ADG and RDI are not proper plaintiffs, and EDC is not a proper defendant, which alone is a sufficient ground on which to dismiss the complaint as against it. There can be no breach of contract claim against a non-signatory to the contract (Nuevo El Barrio Rehabilitación de Vivienda y Economía, Inc. v Moreight Realty Corp., 87 AD3d 465, 467 [2011]). There can be no claim of breach of the implied covenant of good faith and fair dealing without a contract (American-European Art Assoc. v Trend Galleries, 227 AD2d 170, 171 [1996]). And there can be no quasi-contract claim against a third-party non-signatory to a contract that covers the subject matter of the claim (Bellino Schwartz Padob Adv. v Solaris Mktg. Group, 222 AD2d 313, 313 [1995]).
