However, not all of the disputes involving territorial sovereignty are excluded from the jurisdiction of the court or tribunal. Provided that the court judgment or arbitral award will not affect the settlement of the sovereignty dispute between the disputed states or the claim to sovereignty of any state, it may, to a certain extent, has jurisdiction over a dispute of the interpretation and application of UNCLOS with territorial sovereignty disputes ancillary to it.
