The Duty to Investigate Violations of the Right to Life in Armed Conflicts in the Jurisprudence of the Inter-American Court of Human Rights

Abstract

This article explores how the Inter-American Court of Human Rights (the Court) has dealt with allegations of violations of the right to life during an armed conflict and, in particular, how it has dealt with allegations of violation of the obligation to investigate such allegations. The article notes that international humanitarian law (IHL) was initially used by the Court to strengthen the general obligations of states to protect the rights guaranteed by the American Convention on Human Rights (ACHR). Later IHL began informing the interpretation of specific rights. This change has been more significant in relation to the interpretation of the right to life under the ACHR than in the examination of state compliance with the right of access to justice, which encompasses the duty to investigate allegations of violations of the right to life during an armed conflict. The analysis of the Court's jurisprudence demonstrates that the different ways in which the Court has addressed the relationship between IHL and international human rights law (IHRL) have been informed by its primary effort to ensure that the interpretation of the ACHR provides the widest protection possible to individual rights.
