We read with interest the comments of Prof John Ruggie, the former Special Representative of the Secretary General on Business and Human Rights (SRSG), on our new co-edited book entitled, Human Rights Obligations of Business: Beyond the Corporate Responsibility to Respect?, which were posted on the website of the Business and Human Rights Resource Centre. Prof Ruggie recognises that the “contributing authors address both the strengths and weaknesses of the GPs”. He, however, has “real problems” with the Introduction (which was jointly written by us) and our individual chapters in the book. He thus saw it necessary to respond to our work and, in the spirit of robust discussion and debate, we wish to respond and engage with some of the key points made by Prof Ruggie. Clearly, this document cannot be exhaustive or comprehensive – it simply outlines, in brief, our lines of response.
