Amicus brief submitted to the Inter-American Commission of Human Rights after Castle Rock police department failed to enforce an order of protection against Ms. Gonzales’s husband. This brief argues that there is an international consensus recognizing states’ obligation to protect against domestic violence and provide effective remedies for its victims. Even if laws and orders are issued, they must be enforced. The police failure to enforce the protective order in this case, together with the United States’ failure to provide a judicial remedy for this lack of enforcement, violate established international human rights treaties and standards, under which states are required to respect, protect, and fulfil women and girls’ rights to be free from gender-based violence, including domestic violence.
