Henry Billings Brown,
Cowley v. Northern Pacific Railroad Company…
“ If any action or proceeding in a state court were subject to be defeated or impaired by one of the parties exercising his statutory right to remove it to a federal court, no one would be safe in instituting such a proceeding in any case wherein, by reason of diversity of citizenship or otherwise, it might be subject to removal. While the federal court may be compelled to deal with the case according to the forms and modes of proceeding of a court of equity, it remains in substance a proceeding under the statute, with the original rights of the parties unchanged. ”
