10. Desertion.—
In the maritime law, desertion consists in quitting the ship and service by a sailor, without leave and against his duty, without an intent to return. If not justified, it works a forfeiture of wages. The mitigating circumstances must be such as amount to a reasonable excuse, founded on gross misconduct of the master or hard usage. Slight and transient causes will not answer, especially where the desertion appears to have been deliberate and premeditated, and not the result of sudden impulse. It was formerly the law that a deserting seaman might be arrested and imprisoned on shore by local magistrates on the complaint of the master and so compelled to return to his service (Robertson v. Baldwin, 165 U. S. 275). Recent legislation, however, has repealed the older statutes and there are now no laws of the United States which authorize the imprisonment of seamen deserting from vessels owned by citizens of the United States. This is probably true also in the case of foreign-owned vessels within American ports (Ex parte Larsen, 233 Fed. 708). Among the causes which have been held to justify desertion are sickness, unwholesome food, cruel treatment, deviation and unseaworthiness. But the justification must be clearly shown, for it is a serious thing to quit the ship, and the law will not permit it unless the reasons are sound and substantial. Of course, besides the forfeiture of wages which desertion entails, the deserter will be liable to the owner for such damages as his breach of contract may cause. The offense may be committed by any member of the ship's company.
