Performance and quality

The average duration of a case remained at eleven months. The average time between closure and award was 45 days. The expedited procedure took 5.8 months on average. The rate of voluntary compliance rose by two points.

The satisfaction survey shows that 92% of parties say they are satisfied or very satisfied, notably with the quality of the arbitrators (95%) and the clarity of the procedure (91%). The points for improvement concern cost (68%) and the time taken to constitute the tribunal.

Finances and outlook

The tribunal's budget is balanced by registration fees and administrative costs. Funding assistance benefited 31 parties for a total of €187,000. No OIMAP funding is needed for the tribunal's day-to-day running, which guarantees its independence.

The 2025 objectives include the consolidation of multiple proceedings, publication of guidelines on third-party funding of disputes and the launch of an online mediation platform.

Acknowledgements and governance

The report pays tribute to the arbitrators, mediators, experts and staff of the Registry. It also presents the composition of the council, the committees and the rules of governance. The council met six times and held an extraordinary session devoted to the revision of the Rules.

Finally, it recalls the institution's ethical commitments: independence, transparency, combating conflicts of interest and respect for diversity.
