In order to institute suits in the Courts of Admiralty in the United States it is necessary that the voyage should be on tidal waters, and that the service on which suit is brought should be connected with commerce and navigation. The jurisdiction of those Courts in America extends to personal suits, and includes claims founded in contract and in wrong, and also those cases where claims, founded in a hypothecary interest of the nature of a lien, are urged and adjudicated upon. Their jurisdiction extends, moreover, to those cases in which shares of fish, taken on the Bank and other Cod-fisheries, and of oil in the Whale-fishery, are claimed; and, as in English Courts, the seaman may unite his claims, though founded on distinct contracts, in one suit, but this only when demanding wages. The Courts of Common Law in the United States also take cognizance of mariners’ contracts, but they are not competent to give a remedy so as to enforce the mariner’s lien on the vessel; hence, they confine their jurisdiction to personal suits against the master or owner, in accordance with the contract made with the seaman; but, in cases of tort committed on the high seas, and where the form of action is trespass, or a special action, the common law has concurrent jurisdiction. The laws of the United States[14] expressly provide that the crews of merchant vessels shall have the fullest liberty to lay their complaints before their consuls abroad, and shall in no respect be restrained therein by any master or officer, unless some sufficient and valid objection exist against their landing, in which case it is the duty of the master to apprize the consul forthwith, stating the reason why the seaman is not permitted to land; whereupon, the consul must proceed on board, and act as the law directs. In all cases where deserters are apprehended the consul is required to investigate the facts, and, if satisfied that the desertion was caused by unusual or cruel treatment, the mariner shall be, in such case, not merely discharged, but shall receive, in addition to his wages, three months’ pay, and the whole act is required to be entered upon the crew-list and shipping articles, with full particulars of the nature of this treatment. Any consul or commercial agent of the United States neglecting or omitting to perform his duties, or guilty of malversation or abuse of power, is liable to an action from the parties aggrieved; and, for corrupt conduct in office, he is liable to indictment, and on conviction may be fined from one to ten thousand dollars, and be imprisoned not less than one, or more than five, years.
