Forced workplace arbitration

1. Whether a court of appeals may summarily deny a petition for a writ of mandamus challenging a district court’s order compelling arbitration—an order not otherwise appealable under 9 U. S. C. § 16(b)—without addressing sworn, uncontroverted evidence that no arbitration agreement was ever formed, where mandamus is the petitioner’s only avenue for review before an arbitral award issues. 2. Whether the Federal Arbitration Act preempts a generally applicable state employment-protection statute—here, the Illinois Workplace Transparency Act, 820 ILCS 96/1-1 et seq., as amended—that voids a non-negotiated choice-of-law clause imposed on an employee as a condition of a pre-dispute arbitration agreement, where the statute does not single out arbitration for disfavored treatment. 3. Whether a delegation clause assigning all questions of an arbitration agreement’s formation and enforceability to the arbitrator is itself enforceable where it was imposed in the same non-negotiated, adhesive manner as the remainder of the agreement and lacks mutuality.
