Cowles v. Marshall ( 1788 )

By the whole Court:

If the facts stated in the petition can be supported by legal proof the petitioner hath an adequate remedy at law.—He doth not pray for the admission of any evidence for the disclosure of facts which he could not have the benefit of, in a trial at law, therefore, he is not entitled to relief in a court of equity which would deprive the opposite party of the privilege of a trial by jury, and of appeal, if aggrieved by the judgement.
