| Nevertheless, the Supreme Court's unequivocal stand to date |
as to the preemptive effect of the FAA provides strong reason |
to believe that a similar result will obtain with regard to |
Section 10(a) grounds for vacatur. If it does, and if the |
Supreme Court eventually determines that the Section 10(a) |
standards are the sole grounds for vacatur of commercial |
arbitration awards, FAA preemption of conflicting state law |
with regard to the "back end" issues of vacatur (and |
confirmation and modification) would be certain. If the Court |
takes the opposite tack and holds that the Section 10(a) |
grounds are not the exclusive criteria for vacatur, the |
preemptive effect of Section 10(a) would most likely be |
limited to the rule that state arbitration acts cannot |
eliminate, limit or modify any of the four grounds of party |
and arbitrator misconduct set out in Section 10(a). Any |
definitive federal "common law," pertaining to the |
nonstatutory grounds for vacatur other than those set out in |
Section 10(a), articulated by the Supreme Court or established |
as a clear majority rule by the United States Courts of |
Appeals, likely would preempt contrary state law. A holding by |
the Supreme Court that the Section 10(a) grounds are not |
exclusive would also free the States to codify other grounds |
for vacatur beyond those set out in Section 10(a). |
