Artikel 12

Each Contracting State shall have the power, at the time of signing or ratifying this Convention, of declaring that it reserves the right of limiting the transport of emigrants, in accordance with the provisions of its own legislation to vessels which have been granted special authorisation as fulfilling the requirements of the said legislation. In exercising this right, however, the Contracting State shall be guided, as far as possible, by the principles of this Statute.
The vessels so authorised to transport emigrants shall enjoy all the benefits of this Statute in all maritime ports.
