Court of Chancery Holds Arbitrator Decides Limitations Defense
The Delaware Arbitration Act has a unique provision that permits the Court of Chancery to enjoin an arbitration when the claim asserted is barred by a statute of limitations. However, to get into Court, the arbitration agreement must be governed by Delaware's Arbitration Act. If it is not, then this unique remedy is not available, and it is up to the arbitrator to decide if the claim is barred on limitations grounds.
This decision also contains an excellent discussion of when the Delaware Arbitration Act applies and, when it does, to what extent its provisions control.
