Substantive and Adjective Criminal Law in Mexico: social control for the prevention and repression of criminal conduct

This study aimed to analyze the persistent human rights violations within the Mexican criminal justice system, despite the reforms implemented. The main objective was to examine the role of formal social control in crime prevention and repression, as well as to evaluate the effectiveness of substantive and procedural criminal law in protecting fundamental rights. To conduct this research, an review of specialized literature and reports from international and national organizations was carried out. The results reveal that, despite normative advances, practices such as torture, arbitrary detention, and inhumane prison conditions persist. These violations are exacerbated by the lack of judicial independence, corruption, and impunity. The analysis of substantive and procedural criminal law showed that, while there are advances in legislation, problems such as the imprecision of some criminal offenses, the workload of system operators, and the lack of resources persist. In conclusion, the Mexican criminal justice system faces significant challenges in protecting human rights. A comprehensive reform is required that addresses the structural causes of violations, strengthens judicial independence, professionalizes police forces, and guarantees access to justice. Furthermore, it is essential to promote a culture of legality and respect for human rights.
