Summary

The opening of the case’s Wikipedia article: what the case was about and what the Court held.

Dean Witter Reynolds Inc. v. Byrd, 470 U.S. 213 (1985), is a United States Supreme Court case concerning arbitration. It arose from an interlocutory appeal of a lower court's denial of brokerage firm Dean Witter Reynolds' motion to compel arbitration of the claims under state law made against it by an aggrieved former client. The Court held unanimously that the Federal Arbitration Act required that those claims be heard that way when the parties were contractually obligated to do so, even where parallel claims made under federal law would still be heard in federal court.

Justice Thurgood Marshall wrote for the court, resolving a conflict between the appellate circuits; Byron White added a concurrence in which he noted some issues with the underlying securities law that were not before the Court but, he felt, could in future cases make it harder for parties such as Byrd to claim that federal law always allowed them to litigate private actions for securities fraud. In the aftermath of the decision many district courts followed his opinion, leading to later Supreme Court rulings that greatly favored arbitration over litigation in securities disputes. It has been described as completing the federalization of American arbitration law.

Data notes

Each justice’s vote and what they wrote are from the justice-centered file of the Supreme Court Database. “Wrote a concurrence” means the justice sided with the majority and wrote separately; a justice who dissented in part is counted on the side they took overall. A justice who wrote nothing is listed as joining their side.

Positions are each justice’s Martin–Quinn score for the case’s term, the same scores as the Ideology page: negative is more liberal, positive more conservative. A score sums up a justice’s votes across the whole term, so it says where they usually sit, not why they voted as they did here. The median line is the Court’s median justice that term.

Data notes

The Supreme Court Database codes the main constitutional provision, statute or court rule each case turned on, and the basis of the decision: judicial review of a federal or state law, interpreting a statute, supervising the lower courts, and so on. A case can rest on more than one. “Overruled” counts only where the majority opinion says so.
