A detention order might be appealed using the national appeal procedure. When this procedure is not utilised, the owner or operator or its representative in the State concerned, might contest the decision, submitting a complaint to the flag State or the recognised organisation (if authorised to act on behalf of the flag State). The flag State or recognised organisation should review the case. If they are of the opinion that the detention should be overturned then they may then submit a reconsideration request to the port State regarding its decision to detain the ship, including all, relevant, supporting information.
In such cases the port State should investigate the decision and inform the flag State or the recognised organisation of the outcome. If the port State agrees to reverse its decision it should also inform the Information System Manager and the Secretariat.
If the flag State or recognised organisation disagrees with the outcome, or if the port State's outcome is not received 90 days a request for detention review may be submitted to the Secretariat within 120 days of the ship's release. The request must include all relevant information and any prior requests for reconsideration, in electronic format (email) and in English.
If the port State is also a member of another PSC MoU, the Secretariat will liaise with the Secretariat of the other relevant PSC MoU.
Upon receiving a request for a detention review, the Secretariat will assess its validity, considering factors such as the applicable timeframe for submitting the request, previous request to the Port State, if the request is submitted by a flag State and/or RO, and if all detainable deficiencies are challenged.
If the request is accepted, the Secretariat will gather all relevant information, including:
The Secretariat will inform the port State of the review request by electronic means, including a copy of the complaint letter, and invite the port State to submit relevant information via email. If the port State does not reply within 10 working days, the DRP will proceed with the review, based on the information submitted by the flag State and/or recognised organisation.
The Secretariat will set up a “Detention Review Panel (DRP)” comprising of itself and 4 MoU Authorities, requested on an rotating basis, excluding the port and flag State. Once the panel is formed, a virtual meeting will be scheduled within 10 working days, organized by the Secretariat. During the meeting, the Secretariat will present the case and all relevant information without prejudging the outcome. Panel members will have 10 working days to submit their opinions to the Secretariat. which will then share these with all panel members for information.
The Detention Review Panel will:
If a Panel member requires additional information, the Secretariat is to be contacted to ensure that all members receive the same information. Panel members are invited to execute their task following Annex 1 of this instruction.
When no unanimous opinion is reached, a virtual meeting will be organized by the Secretariat to discuss the difference in opinions and attempt to achieve unanimity. If unanimity cannot be achieved, the panel's recommendation will be based on the majority opinion.
The Secretariat will prepare a summary of the opinions of the DRP within 30 working days of accepting the request and will inform the flag State or the recognised organisation, as appropriate, of the outcome of the review. The port State and the MoU Advisory Board will receive the summary of opinions. Copies will be sent to the DRP members. The detail of correspondence between the DRP and the port State will be kept as an internal matter.
If DRP supports the flag State or recognised organisation’s complaint, the port State will be requested to reconsider its decision.
The DRP’s findings are not binding but may provide justification for the port State to amend its inspection data in the Information System and to inform the Information System Manager and the Secretariat accordingly. The Secretariat will inform the flag State or recognized organization, as appropriate, on the action (or not) taken by the port State, with copies sent to the MoU Advisory Board (MAB) and the DRP members for their records.
The Secretariat will prepare an ongoing overview for every MAB meeting about results / status of the review.
The Secretariat will prepare an anonymous summary of the completed cases and publish it on the internal part of the website in order to improve harmonisation of inspections.
The MAB will submit an annual report on the activities of the DRP to the Port State Control Committee.
