Managing an Appeal against a Detention
Appeal time limits, authority, form and effect depend on the notification and port-State law; flag, RO and P&I provide support only within the applicable procedure.
Operational Explanation
SOLAS I/19(f) protects against undue detention or delay. A concrete appeal follows the law, notification and procedure of the port State and competent regime. The Paris MoU format, including information on the reverse of a form, is not universal.
Regulatory Reference
Every regional PSC MOU (Paris MoU, Tokyo MOU, etc.) provides an appeal procedure against detention decisions, with specific details printed on the detention notification form and varying between member States; the right of appeal is a common principle across all regional PSC regimes.
Above the MoU procedures, however, sits a Convention right worth knowing before opening a dispute. SOLAS Regulation I/19(f) reads: “When exercising control under this regulation all possible efforts shall be made to avoid a ship being unduly detained or delayed. If a ship is thereby unduly detained or delayed it shall be entitled to compensation for any loss or damage suffered”.
Two words carry the whole provision. Unduly: it is not enough that the detention was lifted, or that the deficiency was later closed. The detention must have been undue, that is, imposed without the conditions of I/19(b) and (c). A detention founded on real clear grounds and then resolved by repair is not undue and opens no right. And shall be entitled: the wording is mandatory, not permissive — which does not make compensation automatic, but does mean the port State's legal order must provide a route to obtain it.
The same right is restated, in recommendatory form, at paragraph 2.1.4 of the Procedures for Port State Control, 2025 (Res. A.1206(34)), where the verb becomes “should”. In arguing an appeal, cite the Regulation rather than the resolution: the first is treaty law binding on the port State, the second is the procedure that State is invited to follow. Note finally that XI-1/4, at paragraph 3, applies the I/19 procedures to operational control: the protection against undue detention therefore also covers detentions grounded on crew familiarisation failings.
Scope of Application
Treat each detention under the procedure identified by the detaining authority. Time limit, competent body, form, suspensive or non-suspensive effect and reconsideration differ.
Procedure / How to Complete It
- Read the notification and national procedure immediately.
- Preserve appeal deadline and form without waiting only for technical rectification.
- Engage flag, RO, P&I or counsel as support where admitted.
- Keep formal appeal, reconsideration and deficiency closure distinct.
Practical Example
Example: after a detention for a deficiency contested as incorrectly assessed by the PSCO, the operator files a formal appeal with the maritime authority of the port State, attaching the Classification Society's technical documentation; at the same time, it arranges correction of the contested deficiency anyway, so as not to prolong the ship's hold while awaiting the outcome of the appeal.
What Typically Goes Wrong
Common Mistakes Mistake Library
| Mistake | Consequence | How to avoid it |
|---|---|---|
| Appeal addressed to the individual PSCO who carried out the detention instead of the competent maritime authority of the port State | Appeal not processed according to the correct formal procedure | Always check the appeal procedure details on the notification form and address it to the correct competent authority |
| Correction of deficiencies postponed while awaiting the outcome of the appeal | Unnecessary prolongation of the ship's hold, since detention is not suspended during the appeal | Proceed in parallel with correcting the deficiencies, regardless of the expected outcome of the appeal procedure |
| Coordination with the Classification Society and P&I Club started late relative to the decision to file an appeal | Insufficient technical and legal support to effectively sustain the appeal | Involve the Classification Society and P&I Club promptly in assessing and preparing the appeal |
What the PSCO Checks
Operational Tips
- Never assume that an appeal suspends the detention: always check this critical point before planning the ship's operational schedule.
- Involve the Classification Society and P&I Club promptly in assessing the merits and preparing the appeal.
- Treat a complaint to the flag Administration or the RO as a complementary, not alternative, channel to the official appeal procedure.
Preparation checklist
Educational checklist. This summary supports learning and preparation only. It does not replace the vessel’s approved procedures, manuals, statutory documents, company SMS, or applicable official requirements. Completing it demonstrates neither compliance nor readiness for an inspection: it shows that a list has been read, not that the ship is in order. Always verify the current documents carried on board.
- Appeal procedure details checked on the detention notification form
- Appeal addressed to the correct maritime authority of the port State
- Classification Society and P&I Club involved promptly
- Correction of deficiencies initiated in parallel, without waiting for the outcome of the appeal
- Any complaint to the flag Administration/RO considered as a complementary channel
