If the State of arrival refuses admission to persons, vehicles, animals or goods, or if persons refuse to submit to the frontier controls of the State of arrival, or send or take back any vehicles, animals or goods which are accompanying them, the authorities of the State of departure may not refuse to accept back such persons, vehicles, animals or goods. However, the authorities of the State of departure may take any measures to deal with them in accordance with the law applicable in that State and in a way which does not impose obligations either on the State of transit or on the State of arrival.
