9. General Considerations.—
The study of maritime law has the double attraction of historical and practical interest. It deals with the legal affairs of one of the most important phases of modern commercial activity and its problems are solved by precedents from a remote past. It is not a law which is confined within the narrow circle of the present or the limits of particular countries. It is ancient and international. At a time when this country is on the threshold of a revival of its merchant marine, and when there is also a general feeling that it is necessary to proceed to a constructive readjustment and restatement of our entire body of law, the law of the sea, which is really part of the law merchant, must not be neglected. The present is imperfectly understood when the past is forgotten and it is difficult to appreciate any rule without considering its origin. Maritime law is not an exception. Its story presents all the attractions which incline the student to the study of history. It is profitable to follow here, as in politics, the development of ideas and customs, the efforts to accommodate the necessities of commerce by sea to those of the land, the methods of regulating the varied interests on shipboard and those between the shipowner and the ship's company, and the experiments towards ameliorating the age-long friction between the capitalist who supplied the ship and those who labored in her navigation. Through it all appears a constant search for justice, a sincere effort to accomplish what is right and fair for all concerned.
Here one may trace, for example, the rule of general average, the doctrine that what is sacrificed for the common benefit shall be compensated by a common contribution, a rule of such plain and simple equity that the failure of other codes to adopt it is a constant surprise. It appears in a fragment of Greek legislation and forms the text for a chapter in the Digest of Justinian. Its antecedents were probably Phœnician. It survived the Roman Empire in the traditions of seafaring men and reappears in the compilation of sea laws which Cœur-de-Lion revised on his return from the Holy Land, the Rolls or Judgments of Oléron. The Black Book of the admiralty preserves it in London. It may be traced through the Middle Ages down to the York-Antwerp Rules of 1890 and the practice of adjusters of the present day.
Or one may consider the treatment of employer's liability for injuries received in the course of the employment without his personal fault. Is vicarious liability the true test or the doctrine of fellow service? The merchants of the Mediterranean had the problem in the operations of a very large and extended commerce and the maritime law evolved the doctrine that justice requires that one injured in the service of the ship should be cured at the expense of the ship, and have his wages but no more. The last word on the real equity of this solution of a perplexing economic question remains to be said, perhaps, but the student can trace its development and application through many centuries down to the current decisions of our own Supreme Court.
On no other branch of law have tradition and custom exercised a greater influence. It grew out of the necessities of navigation and commerce by sea and remains substantially uniform in spite of forms of government, racial habits and local innovations. In its essence, it is less susceptible of statutory modification than the common law and careless legislation has had only local effects, diverting business into other channels but ineffective to change the substance of the law. Maritime commerce is naturally free and the wisest commercial governments are those which regulate it least. Its freedom is a direct implication from the doctrine of the natural freedom of the seas. The extent to which governments may profitably regulate it without impairing its usefulness or diverting the current to other shores may be found in the history of this law. Underlying principles are the same whether ships move by sail or steam or electricity or are great or small. There have been large vessels before the twentieth century and an equivalent commerce. The law has remained the same. Men pay damages every day in some of our ports for overlooking rules that were current in Roman times and needless litigation is carried through appellate courts because of professional and judicial failures adequately to investigate the underlying principles of the maritime law.
The opportunities for the student are large and inviting. If this country is to do its part in the commerce of the future, its own maritime laws must be restated and reformed. This means not only the formal statutes and department regulations but also the great mass of judicial opinions of more than a hundred years. All are intertwined with each other and the result is chaotic. The fault has not been in the underlying principles of the maritime law but in legislation and interpretation. Our peculiar system has left the final word in the majority of decisions to judges trained in the common law and not professionally acquainted with any other. The result calls for the treatment which Justinian administered to the incongruous compilations, statutes and reports of his time. The student, either of business, history or law, who will apply himself to an investigation of the law of the sea and ascertain its simple fundamentals will not only have an interesting and profitable occupation but also be in a position to contribute substantially to the public welfare.
