Koagne argued that instruments such as the Guiding Principles on Business and Human Rights, due to their voluntary nature, have allowed companies to systematically choose to defend their own commercial interests over the rights of the communities in their territories.

Therefore, he considers a binding treaty is crucial to regulate the violations perpetrated by transnational corporations and to recognize their “extraterritorial obligations”: these companies should respond for their crimes in their countries of origin, but also in the other countries where they operate.
