Day & Zimmermann, Inc. v. Challoner

Summary

The Court, in a per curiam opinion, held that the federal district court must apply the conflict‑of‑law rules of the state in which it sits—in this case Texas—under Klaxon, vacating the Fifth Circuit's judgment and remanding for further proceedings. Justice Blackmun filed a brief concurrence, noting that while he would have denied certiorari, he agrees with the per curiam opinion’s directive that the appellate court apply Texas choice‑of‑law rules, though it may still find Texas strict liability applicable.
