§ 31. At the end of the nineteenth century, in 1899, the so-called Peace Conference at the Hague, convened on the personal initiative of the Emperor Nicholas II. of Russia, has shown the possibility that parts of the Law of Nations may well be codified. Apart from three Declarations of minor value and of the convention concerning the adaptation of the Geneva Convention to naval warfare, this conference has succeeded in producing two important conventions which may well be called codes—namely, first, the "Convention for the Pacific Settlement of International Disputes," and, secondly, the "Convention with respect to the Laws and Customs of War on Land." The great practical importance of the first-named convention is now being realised, as the Permanent Court of Arbitration has in a number of cases already successfully given its award. Nor can the great practical value of the second-named convention be denied. Although the latter contains, even in the amended form given to it by the second Hague Peace Conference of 1907, many gaps, which must be filled up by the customary Law of Nations, and although it is not a masterpiece of codification, it represents a model, the very existence of which teaches that codification of parts of the Law of Nations is practicable, provided the Powers are inclined to come to an understanding. The first Hague Peace Conference has therefore made an epoch in the history of International Law.
Work of the second Hague Peace Conference and the Naval Conference of London.
§ 32. Shortly after the Hague Peace Conference of 1899, the United States of America took a step with regard to sea warfare similar to that taken by her in 1863 with regard to land warfare. She published on June 27, 1900, a body of rules for the use of her navy under the title "The Laws and Usages of War at Sea"—the so-called "United States Naval War Code"—which was drafted by Captain Charles H. Stockton, of the United States Navy.
Although, on February 4, 1904, this code was by authority of the President of the United States withdrawn it provided the starting-point of a movement for codification of maritime International Law. No complete Naval War Code agreed upon by the Powers has as yet made its appearance, but the second Hague Peace Conference of 1907 and the Naval Conference of London of 1908-9 have produced a number of law-making treaties which represent codifications of several parts of maritime International Law.
The second Hague Peace Conference met in 1907 and produced not less than thirteen conventions and one declaration. This declaration prohibits the discharge of projectiles and explosives from balloons and takes the place of a corresponding declaration of the first Hague Peace Conference. And three of the thirteen conventions, namely that for the pacific settlement of international disputes, that concerning the laws and customs of war on land, and that concerning the adaptation of the principles of the Geneva Convention to maritime war, likewise take the place of three corresponding conventions of the first Hague Peace Conference. But the other ten conventions are entirely new and concern: the limitation of the employment of force for the recovery of contract debts, the opening of hostilities, the rights and duties of neutral Powers and persons in war on land, the status of enemy merchant ships at the outbreak of hostilities, the conversion of merchant ships into war ships, the laying of automatic submarine contact mines, bombardments by naval forces in time of war, restrictions on the exercise of the right of capture in maritime war, the establishment of a Prize Court, the rights and duties of neutral Powers in maritime war.
The Naval Conference of London which met in November 1908, and sat till February 1909, produced the Declaration of London, the most important law-making treaty as yet concluded. Its nine chapters deal with: blockade, contraband, unneutral service, destruction of neutral prizes, transfer to a neutral flag, enemy character, convoy, resistance to search, compensation. The Declaration of London, when ratified, will make the establishment of an International Prize Court possible.
Value of Codification of International Law contested.
§ 33. In spite of the movement in favour of codification of the Law of Nations, there are many eminent jurists who oppose such codification. They argue that codification would never be possible on account of differences of languages and of technical juridical terms. They assert that codification would cut off the organic growth and future development of International Law. They postulate the existence of a permanent International Court with power of executing its verdicts as an indispensable condition, since without such a court no uniform interpretation of controversial parts of a code could be possible. Lastly, they maintain that the Law of Nations is not yet at present, and will not be for a long time to come, ripe for codification. Those jurists, on the other hand, who are in favour of codification argue that the customary Law of Nations to a great extent lacks precision and certainty, that writers on International Law differ in many points regarding its rules, and that, consequently, there is no broad and certain basis for the practice of the States to stand upon.
Merits of Codification in general.
§ 34. I am decidedly not a blind and enthusiastic admirer of codification in general. It cannot be maintained that codification is everywhere, at all times, and under all circumstances opportune. Codification certainly interferes with the so-called organic growth of the law through usage into custom. It is true that a law, once codified, cannot so easily adapt itself to the individual merits of particular cases which come under it. It is further a fact, which cannot be denied, that together with codification there frequently enters into courts of justice and into the area of juridical literature a hair-splitting tendency and an interpretation of the law which often clings more to the letter and the word of the law than to its spirit and its principles. And it is not at all a fact that codification does away with controversies altogether. Codification certainly clears up many questions of law which have been hitherto debatable, but it creates at the same time new controversies. And, lastly, all jurists know very well that the art of legislation is still in its infancy and not at all highly developed. The hands of legislators are very often clumsy, and legislation often does more harm than good. Yet, on the other hand, the fact must be recognised that history has given its verdict in favour of codification. There is no civilised State in existence whose Municipal Law is not to a greater or lesser extent codified. The growth of the law through custom goes on very slowly and gradually, very often too slowly to be able to meet the demands of the interests at stake. New interests and new inventions very often spring up with which customary law cannot deal. Circumstances and conditions frequently change so suddenly that the ends of justice are not met by the existing customary law of a State. Thus, legislation, which is, of course, always partial codification, becomes often a necessity in the face of which all hesitation and scruple must vanish. Whatever may be the disadvantages of codification, there comes a time in the development of every civilised State when it can no longer be avoided. And great are the advantages of codification, especially of a codification that embraces a large part of the law. Many controversies are done away with. The science of Law receives a fresh stimulus. A more uniform spirit enters into the law of the country. New conditions and circumstances of life become legally recognised. Mortifying principles and branches are cut off with one stroke. A great deal of fresh and healthy blood is brought into the arteries of the body of the law in its totality. If codification is carefully planned and prepared, if it is imbued with true and healthy conservatism, many disadvantages can be avoided. And interpretation on the part of good judges can deal with many a fault that codification has made. If the worst comes to the worst, there is always a Parliament or another law-giving authority of the land to mend through further legislation the faults of previous codification.
