When an operator sends such a complaint, the flag State or Recognized Organization may then ask the port State to reconsider its decision to detain the ship.

If the flag State or the Recognized Organization disagrees with the result of the investigation as mentioned above, a request for review may be sent to the Paris MoU Secretariat.

To complete the detention review procedure and include the outcome in the 2018 Paris MoU Annual Report, cases concerning detentions in 2018 shall be submitted before 15 February 2019.
