Edward Douglass White, San Francisco National Bank v. Dodge…
“ And though we have repeatedly decided in this court that the statute of a state cannot control the mode of procedure in equity cases in Federal courts, nor deprive them of their separate equity jurisdiction, we have also held that, where a statute of a state created a new right or provided a new remedy, the Federal courts will enforce that right, either on the common-law or equity side of its docket, as the nature of the new right or new remedy requires. ”
