Harlan F. Stone,
Stratton v. St. Louis Southwestern Railway Company…
“ The fact that in them the suits brought were denominated 'equitable,' although the only relief of an equitable nature, sought or allowed, was the injunction against payment over of the tax, which was but incidental to the recovery of the money, cannot alter the character of the right as one enforceable at law. In determining what is a legal remedy and its adequacy to defeat their equity jurisdiction, the federal courts are guided by the historic distinction between law and equity in those courts, not by the name given to remedies or to distinctions made between them by the state practice. ”
