On November 6, 2024, the French Supreme Court rejected the enforcement of an interim award on jurisdiction in the legal saga opposing Malaysia to the heirs of the Sultan of Sulu and spanning several jurisdictions. The Supreme Court ruled that the arbitration clause in an 1878 agreement – and on the basis of which a US$15 billion award has since been issued against Malaysia – is null and void. This decision will presumably lead the French Supreme Court to annul the US$15 billion award itself next.
