Proposal to the CSRP EM - Draft request for an advisory opinion to the International Tribunal for the Law of the Sea Mbengue, Y.S. /Brehmer, Patrice Ly, I. This document highlights the pivotal role the CSRP (Sub-Regional Fisheries Commission) can play by seeking an advisory opinion from the International Tribunal for the Law of the Sea (ITLOS). This move would help secure the legal foundation for international regulations that mandate the use of a monitoring system for all fishing vessels on the high seas. To that end, we have formulated two questions for ITLOS. By clarifying the compatibility of this obligation with both the freedom of the high seas and flag State jurisdiction, and by establishing whether such a system constitutes "due diligence" for resource conservation, the CSRP will not only more effectively combat IUU (illegal, unreported, and unregulated) fishing, but also promote sustainable fisheries management. It will also solidify its leadership as a key player in fisheries governance, while simultaneously promoting increased flag State accountability and better harmonisation of maritime surveillance efforts. In addition to these inquiries, we are submitting three further questions, specifically concerning flag State jurisdiction within a coastal State's Exclusive Economic Zone (EEZ) and the extent of its enforcement obligations. This only further strengthens the ambition of this initiative. CSRP 2025 text https://www.documentation.ird.fr/hor/fdi:010097675 fdi:010097675 Mbengue Y.S., Brehmer Patrice, Ly I..
