This paper analyzes the African Court on Human and Peoples’ Rights’ judgment in Augustino and Abdulkarim v. Tanzania, focusing on the interpretation of Article 36(1)(b) of the Vienna Convention on Consular Relations (VCCR) and its integration into the African Charter on Human and Peoples’ Rights. The goal is to examine the Court’s reasoning, assess its alignment with international jurisprudence from the ICJ and IACHR, and highlight its contribution to fair trial guarantees for detained foreign nationals. The study employs a doctrinal analysis of the judgment and comparative review of relevant international case law. It concludes that the AfCHPR’s findings reinforce the global understanding of consular notification as a procedural safeguard, emphasizing its significance in protecting vulnerable individuals and ensuring state accountability under international law.
