The fact that a party did not sign an arbitration agreement is not dispositive of the question of whether it is bound to such agreement. “[A] nonsignatory party may be bound to an arbitration agreement if so dictated by the ‘ordinary principles of contract and agency’” (
Thomson-CSF, SA v Am Arbitration Ass’n, 64 F3d 773, 776 (2d Cir 1995)). Accordingly, traditional state law contract principles govern the applicability of an arbitration agreement to non-signatories. Courts have held that non-signatories may be bound to arbitration agreements under various theories, including:
- incorporation by reference of the agreement to arbitrate into another contract;
- assumption or assignment;
- agency;
- veil-piercing/alter ego;
- third-party beneficiary; and
- estoppel.
(Arthur Andersen LLP v Carlisle, 556 US 624 (2009) (arbitration agreements are enforceable by and against non-signatories, under state law contract principles); Color-Web, Inc v Mitsubishi Heavy Industries Printing & Packaging Machinery, Ltd, 2016 WL 6837156 (SDNY 21 November 2016) (applying estoppel to bind non-signatory plaintiffs and defendants to arbitration, including corporate parents, agent, and successor)).
Independent contractors, however, are not ‘agents’ that can be bound as non-signatories to an arbitration clause (Oudani v TF Final Mile, LLC, 876 F3d 31 (1st Cir 2017)).
