In a judgment delivered on February 28, 2020, the Supreme Court of Canada held (by majority, 7–2) that Canadian common law does not contain an all-encompassing doctrine of non-justiciability based on foreign acts of state; and (by a narrower majority, 5–4) that alleged breaches of customary international law (CIL) arguably provide a novel cause of action in tort. The court held that claims against a Canadian mining corporation related to alleged violations at a mine in Eritrea could proceed to trial.

On June 6, 2018, the International Court of Justice (Court) rendered a judgment on preliminary objections in the case of Immunities and Criminal Proceedings (Equatorial Guinea v. France). France had made three preliminary objections: two related to the Court's jurisdiction on the basis of, respectively, United Nations Convention Against Transnational Organized Crime (Palermo Convention) and the Optional Protocol to the Vienna Convention on Diplomatic Protection (VCDR) concerning the Compulsory Settlement of Disputes (Optional Protocol), and the third challenged admissibility for abuse of process and abuse of rights. The Court accepted the first objection regarding jurisdiction on the basis of the Palermo Convention and rejected the other two. This judgment is an important contribution to the development of international law, both regarding the particular instruments at issue and broader questions of law of treaties and international dispute settlement.

On September 6, 2018, Pre-Trial Chamber I of the International Criminal Court (Court) issued its “Decision on the ‘Prosecution's Request for a Ruling on Jurisdiction Under Article 19(3) of the Statute.’” The decision is notable both for the procedural posture—the Prosecution submitted its request prior to opening a preliminary examination—and the majority's conclusion that the Court may exercise territorial jurisdiction over alleged deportation from Myanmar, a nonstate party to the Rome Statute of the International Criminal Court (Rome Statute or Statute), to a state party, Bangladesh.

On June 10, 2022, by consensus, the International Labour Conference (ILC) adopted a resolution amending the Declaration on Fundamental Principles and Rights at Work to encompass “a safe and healthy working environment.” Under this Declaration, adopted in 1998, all 187 member states of the International Labour Organization (ILO) have an obligation, arising from their membership, “to respect, promote and realize … the principles concerning the fundamental rights” that are the subject of ILO Conventions recognized as fundamental. The other four fundamental categories are freedom of association and the effective recognition of the right to collective bargaining, the elimination of all forms of forced or compulsory labor, the effective abolition of child labor, and the elimination of discrimination in respect of employment and occupation.
