Headnotes

  1. Civil Procedure — Choice of Law In diversity of citizenship cases, a federal court must follow the conflict of laws rules prevailing in the state in which it sits, and may not make an independent determination of what the better or proper conflicts rule should be. 313 U.S. at 496
  2. Civil Procedure — Erie Doctrine The prohibition against independent federal determinations in diversity cases extends to the field of conflict of laws, because otherwise the accident of diversity of citizenship would constantly disturb equal administration of justice in coordinate state and federal courts sitting side by side, and any other ruling would do violence to the principle of uniformity within a state. 313 U.S. at 496
  3. Civil Procedure — Erie Doctrine Where the conflict of laws rules of the forum state govern, the proper function of the federal court sitting in that state is to ascertain what the state law is, not what it ought to be; subject only to review by the Supreme Court on any federal question that may arise, the state is free to determine whether a given matter is governed by the law of the forum or by some other law. 313 U.S. at 496
  4. Civil Procedure — Choice of Law The Full Faith and Credit Clause does not require a state, contrary to its own policy, to give effect in actions brought locally on contracts made in other states to laws of those states relating, not to the validity of such contracts, but to the right to add interest to the recovery as an incidental item of damages. 313 U.S. at 497
  5. Civil Procedure — Choice of Law Nothing in the Constitution ensures unlimited extraterritorial recognition of all statutes or of any statute under all circumstances; the Full Faith and Credit Clause does not compel a forum state to apply another state's statute where such application would interfere with the forum's local policy. 313 U.S. at 497
