This article considers the positive evolution of international law in the past century, and the emergence of a rules-based multilateral system under the UN Charter, which has, inter alia, enabled formerly colonised peoples to exercise their right to self-determination and prohibited the use of force in international relations. The author reaffirms his faith in the ability of international law to provide a common language for the international community to face successfully common challenges, such as poverty, global warming, and the protection of privacy rights in the era of social media and artificial intelligence. Looking beyond traditional beneficiaries and duty-bearers of international obligations, the author makes a case for all actors to engage in respecting, upholding and promoting international law.

Although fair trial guarantees have always been recognised as constituting an integral aspect of international arbitral proceedings, this has largely been viewed through the lens of civil procedure rather than as a matter of public law and human rights. This state of affairs has further been compounded by the confidential nature of arbitration and the relative scarcity of set aside (annulment) proceedings before the courts of the seat of arbitration on the grounds of unequal treatment, and before human rights bodies such as the European Court of Human Rights. Moreover, it has always been difficult to reconcile contractual freedom and the advantages offered by arbitration with equal treatment and fair trial claims. This article demonstrates the existence of a set of general principles concerning the meaning and content of equal treatment, which are consistent with its commercial (and civil procedure) and human rights dimensions. The basis of this conclusion is Article 18 of the UNCITRAL Model Law on International Commercial Arbitration, as consistently interpreted and adapted by local laws and judgments, arbitral statutes and determinations by the European Court of Human Rights.
