Whether Section 2 of the Federal Arbitration Act requires a court to decide any challenge to a delegation provision's validity before the court may proceed to address whether the parties' underlying dispute is arbitrable

QUESTION PRESENTED Where an arbitration agreement contains a separate “delegation provision” that reserves for an arbitrator the authority to decide any disputes concerning arbitrability, does Section 2 of the Federal Arbitration Act require a court to decide any challenge to that provision’s validity before the court may proceed to address whether the parties’ underlying dispute is arbitrable?
