Overview
- The Court publicly notified Advisory Opinion OC-30/2025, affirming a state duty of due diligence built on four pillars: regulation, supervision, effective judicial remedies, and international cooperation.
- States are instructed to ensure firearm marking, registration, and tracing, and to preserve records on manufacture, location, transfers, seizures, and confiscations.
- Authorities must conduct risk assessments before authorizing arms imports or exports and deny exports when significant risks to peace, security, or human rights—especially for vulnerable populations—are identified.
- Governments are told to secure state arsenals and manage seized weapons to prevent diversion, including rules for confiscation, destruction, and deactivation, along with anti-corruption measures targeting organized crime.
- The opinion underscores oversight of companies in the arms sector under human-rights due-diligence standards, a stance Mexico’s Foreign Ministry says supports its broader strategy following U.S. litigation setbacks.
