John Ruggie, appointed UN Special Representative of the Secretary-General on business and human rights has recently released his report, "Protect, Respect and Remedy: a Framework for Business and Human Rights." [PDF]
From the summary:
Responding to the invitation by the Human Rights Council for the Special Representative of the Secretary-General on the issue of human rights and transnational corporations and other business enterprises to submit his views and recommendations for its consideration, this report presents a conceptual and policy framework to anchor the business and human rights debate, and to help guide all relevant actors. The framework comprises three core principles: the State duty to protect against human rights abuses by third parties, including business; the corporate responsibility to respect human rights; and the need for more effective access to remedies. The three principles form a complementary whole in that each supports the others in achieving sustainable progress.
The report will be considered by the United Nations Human Rights Council during the first two weeks of June.
