Ragan v. Merchants Transfer &amp; Warehouse Co.Ragan v. Merchants Transfer &amp; Warehouse Co. Ragan v. Merchants Transfer & Warehouse Co. Ragan v. Merchants Transfer & Warehouse Co., 337 U.S. 530 (1949), is a United States Supreme Court case in which the Court held that federal courts sitting in diversity should begin the running of the statute of limitations for a claim according to state law instead of according to the federal rules of civil procedure. The court reasoned that a claim could not be given longer life in federal court than it would have had in a state court while being consistent with the holding in "Erie Railroad v. Tompkins".
