Human rights, regarded as fundamental and inalienable entitlements, are delineated and safeguarded through a combination of international legal frameworks and national laws. In this article, we conduct an in-depth analysis of the mechanisms for preserving human rights within both the international legal context and the specific framework of Vietnamese criminal law. We also put forth a set of recommendations designed to augment the effectiveness of human rights protection. In practice, the preservation and realization of human rights can be a complex challenge, and there are instances where these rights may be transgressed within the course of judicial proceedings. To tackle this problem, it is imperative that the provisions pertaining to human rights in both international and Vietnamese criminal law are given the requisite attention and adherence. Moreover, to ensure the comprehensive and effective implementation of human rights protection, it is imperative to establish a clear and robust legal framework. Striking the delicate balance between justice and human rights protection remains an ongoing endeavor, demanding continuous vigilance and adaptability in our legal systems. Ultimately, the harmonious coexistence of legal processes and human rights preservation is essential to fostering a just and equitable society.
