John Marshall,
Parker v. the Judges of the Circuit…
“ It is contended, that an injunction could not be awarded while the record was before this Court on a writ of error.We do not think this a valid objection. The suit in Chancery does not draw into question the judgment and proceedings at law, or claim a right to revise them. It sets up an equity independent of the judgment, which admits the validity of that judgment, but suggests reasons why the party who has obtained it ought not to avail himself of it. It proposes to try a question entirely new, which has not been, and could not be, litigated at law. ”
