The Massachusetts Appeals Court has ruled that an arbitrator exceeds her authority only when "she awards relief beyond the scope of the arbitration agreement, beyond that to which the parties bound themselves, or enters an award prohibited by law." Conway v. CLC Bio, LLC, 2015 WL 9883907, Mass. App. Ct. No. 14-P-350 (June 12, 2015), at 5-6. The Court also reiterated that the Federal Arbitration Act ("FAA") requires enforcement of an agreement to arbitrate statutory claims "absent a question of arbitrability, countervailing Congressional command, or cognizable challenge to the validity of the agreement to arbitrate." Id., at 10.
Employers and employees everywhere should check their employee handbooks - if it has an arbitration provision, it is likely any disputes between the two will take place in arbitration rather than in court.
