Unfortunately, in the XXI century Human Rights are still not respected in many countries, mainly in those in the process of development. Faced with this situation, international organizations such as the UN are shifting the focus of responsibility, which was traditionally placed on States, to multinational companies. Therefore, progress is being made towards a public-private co-protagonistism in respect for Human Rights. But it is not only a question of "protecting" and "respecting" human rights, but of "remedying", following the three keys of the UN Guiding Principles, human rights violations, improving access to justice for victims who suffer their violation by multinationals. This paper examines, on the one hand, the main international instruments; subsequently, the problems faced by victims are analysed from a practical point of view; and, finally, some ways are presented to guarantee their access to justice and, ultimately, reparation.
