The master of a ship on arrival, or already in a district, who is unwilling to comply with, or submit to, any provision of, or requirement made, under these regulations which may be applicable shall notify the authorised officer, and the authorised officer may then require the master to remove the ship immediately from the district.

If before leaving the district the master wishes to discharge cargo or disembark passengers or to take on board fuel, water or stores, the authorised officer shall permit him to do so, but may impose such conditions under these regulations as the authorised officer considers necessary.

When the authorised officer has required the removal of a ship from the district, it shall not, during its voyage, call at any other district.
