The objective of this work is to investigate the resolution me-chanism for specific instances of the National Contact Points of the OECD Guidelines for Multinational Enterprises on Responsible Business Conduct as a non-judicial mechanism for access to justice. To this end, the cases processed in Argentina (period 2004-2021) and Spain (period 2001-2023) are analyzed, in order to establish limits and possibilities for their use by social actors, such as unions and NGO in the context of economic globaliza-tion and transnational law.
