The Supreme Court held that because the respondents challenged the entire contract instead of simply the clause requiring arbitration, the arbitration provisions are enforceable apart from the rest of the contract. This is true regardless of state law on void contracts. The challenge to the contract must, therefore, be heard by an arbitrator rather than a court.
