Henry Schein arose from a complaint filed by Archer & White Sales, a small dental equipment distributor, against Henry Schein, LLC, the successor-in-interest to a dental equipment manufacturer, alleging violations of federal and state antitrust law. Henry Schein invoked the dispute resolution provision in the parties' distribution contract and sought to compel arbitration of the dispute. Archer objected, claiming that the dispute was not subject to arbitration, because the dispute resolution carved out actions seeking injunctive relief, and the complaint sought an injunction. Relying on Fifth Circuit precedent, the district court held that where a party's argument for arbitration is "wholly groundless," it has authority to resolve the threshold question of arbitrability, notwithstanding that the agreement expressly incorporated AAA rules that empower arbitrators to resolve arbitrability questions.
