Most states have consuls-general, consuls, vice-consuls, consular agents, sometimes also consular students.

(c) The nomination of consuls is an attribute of a sovereign state. They may be chosen either from among its own citizens or from those of the foreign state. Consuls chosen from the citizens of the state to which they are accredited exercise only in part the full consular functions, the limit of the functions being determined by the laws of the accrediting state and by the laws of the receiving state. Some states refuse to receive their own citizens as consuls; others do not accredit foreigners as consuls.

The commission or patent by which a consul-general or consul is always appointed is transmitted to the diplomatic representative of the appointing state in the state to which the consul is sent, with the request that he apply to the proper authority for an exequatur, by which the consul is officially recognized and guaranteed such prerogatives and immunities as are attached to his office. The vice-consul is usually appointed by patent, though he may be nominated by his superior, and is recognized by granting of an exequatur. The exequatur may be revoked for serious cause, though the more usual way is to ask the recall of a consul who is not satisfactory to a state. The exequatur may be refused for cause. It is usually issued by the head of the state. If the form of government in the receiving state or in the accrediting state changes, it is customary to request a new exequatur.

Note. The consular agents, while appointed and confirmed as are the higher consular officers, do not in the practice of the United States receive an exequatur.

(d) Functions. The consul, as the officer representing particularly the commercial and business interests of the state from which he comes, and in a minor degree the other individual interests, has a great variety of functions. His functions are in general such as affect only indirectly the state in which he resides. He is not, like the diplomatic agent, directly concerned with affairs of state; he has no representative character, though in effect he is often the local representative of the diplomatic agent accredited to the state.

The functions of a consul are largely matters determined by custom, treaty stipulation, and by special provisions of his exequatur. Within these limits domestic law of the accrediting state determines the consul's functions. (1) In general the consul has many duties in connection with the commercial interests of the subjects of the state which he serves. These duties extend both to maritime and land commerce. The consul is to care that the provisions of commercial treaties are observed, that proper invoices of goods are submitted, and that shipment is in accord with the regulations of the state which he serves. He is to furnish such reports in regard to commercial and economic conditions as are required. These reports often involve many subjects only indirectly related to trade and commerce. (2) The consul has many duties relating to the maritime service of the state which accredits him. This usually includes such supervision of merchant vessels as the domestic law of his state may grant to him, together with that accorded by custom. His office is a place of deposit of a ship's papers while the ship remains in port. When necessary he may supervise the shipment, wages, relief, transportation, and discharge of seamen, the reclaiming of deserters, the care of the effects of deceased seamen, in some states the adjudication of disputes between masters, officers, and crews, and if necessary he may intervene in cases of mutiny or insubordination. In case of wrecked vessels the consul is usually left considerable latitude in his action. The consul may also authenticate the bill of sale of a foreign vessel to the subject of the state which accredits him. This authentication entitles the vessel to the protection of the consul's state. The consul may also be intrusted with other duties by treaties and custom of given states. (3) The consul represents the interests of the citizens of the state in whose service he is, in matters of authentication of acts under seal, in administration of the property of citizens within his district, in taking charge of effects of deceased citizens, in arbitration of disputes voluntarily submitted to him, visé of passports, and minor services. (4) The consul furnishes to the state which he represents information upon a great variety of subjects particularly relating to commercial, economic, and political affairs, the conditions of navigation, and general hydrographic information. Besides this he is expected to keep his state informed of the events of interest transpiring within his district.

As Hall says: "In the performance of these and similar duties the action of a consul is evidently not international. He is an officer of his state to whom are entrusted special functions which can be carried out in a foreign country without interfering with its jurisdiction. His international action does not extend beyond the unofficial employment of such influence as he may possess, through the fact of his being an official and through his personal character, to assist compatriots who may be in need of his help with the authorities of the country. If he considers it necessary that formal representations shall be made to its government as to treatment experienced by them or other matters concerning them, the step ought in strictness to be taken through the resident diplomatic agent of his state,—he not having himself a recognized right to make such communications."[260] In late years there has been in the consular conventions between different states a tendency to extend to consuls the right of complaint to the local authorities in case "of any infraction of the treaties or conventions existing between the states," and "if the complaint should not be satisfactorily redressed, the consular officer, in the absence of the diplomatic agent of his country, may apply directly to the government of the country where he resides."[261]

(e) In some of the Eastern and non-Christian states consuls have special powers and functions in addition to the ordinary powers and functions. The extent of the powers varies, and is usually determined by treaty. With the advance of civilization these special functions are withdrawn, as by the Treaty of the United States with Japan, Nov. 22, 1894,[262] the jurisdiction of the consular courts of the United States in Japan came to an end July 17, 1899.
