In 1995, Professor Krzysztof Skubiszewski added a Dissenting Opinion to the East Timor Judgment, wherein the ICJ declined jurisdiction in a proceeding started by Portugal against Australia for its having concluded the East Timor Gap treaty with Indonesia, in blatant violation of the East Timorese’s right to self-determination. Ad-hoc Judge Skubiszewski posited that the Court should have accepted jurisdiction and he presented a series of convincing arguments for this proposition. In 2019 the ICJ rendered an Opinion in the Chagos Islands case. The fact that the ICJ accepted jurisdiction in this case demonstrates that an impressive development has taken place since 1995, one whereby many of Professor Skubiszewki’s requests have been implemented. At the same time however, the Chagos Opinion is not fully satisfying as it neglects, to a considerable extent, the human rights issue. This contribution shows that Skubiszewski’s Dissenting Opinion would have provided guidance also for these questions and that it remains as topical today as it was in 1995.
This article discusses the classical question whether general principles of law form a separate source of international law. To this end it adopts the method of a posteriori analysis, examining the normative nature of various principles of law one by one. This analysis leads to the conclusion that only some principles have a normative nature, while others lack it.
