US Supreme Court rejected a “Wholly Groundless” exception to clauses delegating arbitrability

In Schein, Inc. v. Archer and White Sales, Inc., 586 U.S. the Supreme Court confirmed that when an arbitration agreement delegates to an arbitrator the question of whether the agreement applies to a particular dispute, courts have no power to decide this question, even if a court considers the arbitrability argument to be “wholly groundless.” The Supreme Court thus confirmed the Kompetenz-Kompetenz doctrine recognised in US law.
