Sixth Committee Debate on International Law Commission Report Highlights Work on Official Immunity

Discussion of the International Law Commission's annual report continued in the Sixth Committee (Legal) today, with speakers taking the floor to discuss, among other topics, the appropriate balance to be struck between preventing impunity and respecting sovereign equality when considering the immunity from foreign criminal jurisdiction provided to State officials.

The Commission has been working on this item since 2007, recalled Claudio Grossman, the topic's Special Rapporteur, adding that finalizing this work "carries tremendous significance". Elaborating on developments in 2026, he said that the major advancement was a revision of the draft articles concerning crimes under international law with respect to which immunity ratione materiae (functional immunity) does not apply. While the Commission retained a non-exhaustive-list-based approach regarding these crimes, it expressly included three additional crimes - those of aggression, slavery and slave trade, he noted.

"Their inclusion was not intended as a merely symbolic gesture," he observed; rather, it reflects the Commission's assessment that these offences satisfy the legal criteria for inclusion. Emphasizing that including the crime of aggression "preserves the development of international criminal law since Nuremberg", he described the addition of the other two crimes as "equally significant". Further noting that all draft articles were adopted unanimously, he underscored: "This expresses a significant level of consensus."

This topic "strikes at the difficult and fundamental questions as to the balance between accountability for crimes and respect for sovereign equality", observed Canada's representative. While relevant State practice indicates that certain serious crimes may be recognized as customary exceptions to functional immunity, others - especially those added more recently - do not appear to be supported to the same extent. The question of immunity should be considered in close connection with a preliminary assessment of the criteria establishing jurisdiction, which may vary from State to State, added the representative of Italy.

Some speakers, including the representatives of Croatia and Lithuania, welcomed the Commission's inclusion of the crime of aggression among those to which immunity ratione materiae does not apply, both recalling the aggression they suffered during the 1990s. "As an umbrella crime, aggression is often accompanied by numerous war crimes and crimes against humanity attributed to the leadership, and the consequences of all those severe crimes burden societies for decades," Croatia's representative observed, expressing hope that the draft articles will lead to more legal certainty on this "sensitive issue".

However, the representative of Saudi Arabia said that the gravity of a crime does not suffice to prove an exception from immunity. She said that the list of crimes proposed - particularly that of aggression - is "problematic" due to limited international practice, the non-universality of some instruments and the risk of politicizing the exercise of foreign criminal jurisdiction. Similarly, Serbia's representative noted that certain issues under this topic remain controversial among States. Given its sensitive nature, he suggested further discussion through an international conference of plenipotentiaries.

Sea Level Rise in Relation to International Law

On this topic, the representative of the Gambia observed that her country is "particularly vulnerable" to this phenomenon as a low-lying coastal State. Stressing that the Commission's 2025 report has been "instrumental in providing the requisite analysis in the evolution of rules governing sea level rise", she said that States must respect and protect the human rights of affected persons. "We continue to maintain that persons affected by sea level rise remain right-holders," she said.

Concurring, Costa Rica's representative urged that respect for human dignity should guide States as they develop future normative instruments on this issue. Further, he stressed that sea level rise should not undermine State sovereignty, adding: "The loss of territory, changes to ecosystems and mounting pressures on communities and their livelihoods - including fishing and tourism - reveal a reality that demands immediate attention."

Other Decisions and Conclusions of the Commission

Welcoming the inclusion of the topic "Identification and legal consequences of obligations erga omnes in international law", the representative of Côte d'Ivoire encouraged the Commission to conduct its work in a manner that reflects the diversity of legal traditions and perspectives from all regions.

On another matter, Estonia's representative noted the inclusion of an updated version of the syllabus on extraterritorial jurisdiction, a topic included in the Commission's long-term programme of work in 2006. She said that the Commission could help build a shared understanding of the grounds and limits of jurisdiction, strengthen legal certainty and support cooperation between States.

General Principles of Law

The representative of Paraguay said that the Commission's draft conclusions on this topic "constitute a greater understanding of one of the sources of international law" in the Statute of the International Court of Justice. He observed that identifying these principles requires a sufficiently broad survey of global legal systems to determine the existence of a principle common among them. Adding that this identification - and subsequent transposition to the international legal system - should be done according to established methodology, he said that the Commission's comments are "useful references" in this regard.

For his part, the representative of the Czech Republic said that insufficient State practice, jurisprudence and doctrinal support exist to establish the existence of general principles of law formed within the international legal system. He also expressed concern that such an approach may blur the distinction between general principles of law and other sources of international law - particularly customary international law. Nevertheless, he said that scholarly and intergovernmental discussions on certain aspects of the Commission's draft conclusions should continue.

Emphasizing that the Commission's work offers States useful references for the identification and application of international norms, the representative of Lebanon observed: "This contribution is a part of a broader mission to make the international legal order more coherent, more intelligible and more predictable." Noting that the quality of international law "depends on taking into consideration the diversity of legal traditions and national experiences", he pointed out that "linguistic and legal pluralism enriches the analysis and promotes the development of solutions" that lead to wider State endorsement.

"The diversity of national experiences should be considered not as a constraint but, rather, as a resource," he stressed.
