Chapter VI : Enemy character - Art. 57.
Art. 57. Subject to the provisions respecting transfer to another flag, the neutral or enemy character of a vessel is determined by the flag which she is entitled to fly.
The case where a neutral vessel is engaged in a trade which is closed in time of peace, remains outside the scope of, and is in no wise affected by, this rule.
