ICJ issued advisory opinion on right to strike in 2023. ILO requested it to resolve disputes as 'strike' not in 1948 treaty but walkouts covered. Court heard arguments from 18 countries and five international orgs during October hearings. 14-judge panel voted 10-4 in favor of right to strike. Unions support ruling, though ICJ opinions not legally binding. Expert Paul van der Heijden says decision supports workers facing legal opposition. Court President Yuji Iwasawa notes ruling doesn't define right's scope but may influence laws
