The Updated Set of Principles for the Protection and Promotion of Human Rights through Action to Combat Impunity (2005) represents a cornerstone of contemporary international human rights law. Adopted by the UN Commission on Human Rights, the Principles clarify States’ obligations to investigate serious violations, prosecute perpetrators, ensure victims’ rights to truth and justice, and provide effective reparation and guarantees of non-recurrence. This article presents Victim Support Taiwan’s (VST) curated edition of the Principles, accompanied by an analytical overview from a victim-centered perspective. It explains key concepts such as impunity, universal jurisdiction, and restrictions on amnesty and prescription, while situating the framework within Taiwan’s legal development and regional security context. By linking international standards with domestic reform, the article highlights how combating impunity strengthens the rule of law and affirms victims as active rights-holders under international law.
