Parker v. Winnipiseogee Lake Cotton and Woollen Company…
“ The 16th section of the Judicial Act of 1789 provides, 'that suits in equity shall not be sustained in either of the Courts of the United States in any case where plain, adequate, and complete remedy can be had at law.' This is merely declaratory of the pre-existing rule, and does not apply where the remedy at law, is not 'plain, adequate, and complete,' or, in other words, where it is not 'as practical and as efficient to the ends of justice and to its prompt administration as the remedy in equity.' 3 Pet., 215. ”
