A/HRC/20/16 operative, technical, financial and human resources and, in some cases, a lack of political will to effectively and practically address the problem. 114. In 2007, the Economic Commission for Latin America and the Caribbean concluded that to end violence against women, it is imperative that it become a focus of public agendas: firstly, as a human rights violation, secondly, because violence is an obstacle for development and, finally, because it is a key issue for democracy and governance.189 In this sense, the elimination of violence against women is based on three pillars: legal protection, public policies and a culture of respect without discrimination.190 115. A holistic approach for the elimination of all forms of violence against all women would require that systemic discrimination, oppression and marginalization of women be addressed at the political, operative, judicial and administrative levels.191 116. In cases involving gender-related killings, the international and regional human rights systems have included some of the following standards regarding the due diligence obligations of States: (a) Conduct effective investigations of the crime, and prosecute and sanction acts of violence perpetrated by State or private actors, especially when these acts demonstrate a pattern of systemic violence towards women; (b) remedies; Guarantee de jure and de facto access to adequate and effective judicial (c) Include in the obligation of access to justice a requirement to treat women victims and their relatives with respect and dignity throughout the legal process; (d) Ensure comprehensive reparations for women victims of violence and their relatives, including measures that are designed to address institutional and social factors; (e) Identify certain groups of women as being at particular risk for acts of violence due to having been subjected to discrimination based on more than one factor, including women belonging to ethnic, racial and minority groups. Such factors must be considered by States in the adoption of measures to prevent all forms of violence; (f) Modify the social and cultural patterns of conduct of men and women and eliminate prejudices, customary practices and other practices based on the idea of the inferiority or superiority of either of the sexes, and on stereotyped roles for men and women. 189 190 191 28 Economic Commission for Latin America and the Caribbean (ECLAC), (2007), ― Ni una m s El derecho a vivir una vida libre de violencia en Am rica Latina y el Caribe‖, (LC/L.2808), Santiago de Chile.
