Justice O’Connor, joined by Chief Justice Burger and Justices White, Blackmun, Powell, Rehnquist and Stevens, authored the opinion of the Court, addressing the statutory interpretation issue first. She held that the D.C. Circuit created a false distinction between the CFTC's jurisdiction over state law counterclaims and counterclaims arising under the CEA, simply to avoid a constitutional problem, and ignored the legislative intent of Congress in doing so. The situation faced by the litigants here was common: a claim and counterclaim arising out of the same transaction and occurrence, and it was well within the statutory jurisdiction of the CFTC to adjudicate such both actions. This is in keeping with Congress’ intent to create a more efficient means of adjudicating such disputes, as well as the administration's interpretation of the statute.
