US SUPREME COURT DECISIONS

Whenever a statute grants a new right or a new remedy for the violation of an old right, or whenever such rights and remedies are dependent on state statutes or on acts of Congress, the jurisdiction, as between the law side and the equity side of the federal courts, must be determined by the essential character of the case. Unless it comes within some of the recognized heads of equitable jurisdiction, the remedy of the party is at law.

The facts are stated in the opinion of the Court.
