Labour Court of Appeal Brussels, Confederation of Christian Trade Unions and General Federation of Labour of Belgium v United States, A.R. 2010/AB/1214, 3 May 2012
The jurisdictional immunity of states is a rule of customary international law that prohibits the jurisdictions of one state from exercising its jurisdictional power over another state that has not consented. However, this immunity is limited: it concerns acts relating to sovereignty, not administration. In principle, the states may not invoke jurisdictional immunity before a court of another state in proceedings relating to employment contracts. However, no exception to the states’ jurisdictional immunity is provided for collective labor relations. Disputes concerning the regulations on the establishment of works councils are collective and not individual. The primacy of access to justice (Article 6 of the ECHR) over the rule of jurisdictional immunity and immunity from execution presupposes that the person against whom the immunity is asserted does not have other reasonable means of effectively obtaining the protection of the rights guaranteed to him by the ECHR. What matters in this regard is not that an action can be brought in the state of residence of the plaintiffs or that certainty is provided as to the application of the law of that state by the foreign jurisdiction, but that that jurisdiction (or the body of the international organization to which an internal action can be brought, as in the cases submitted to the Supreme Court) provides the guarantees of impartiality and independence of the court.
