This article outlines the case for a business duty of care to exercise human rights due diligence, judicially enforceable in common law countries by tort suits for negligence brought by persons whose potential injuries were reasonably foreseeable. A parent company’s duty of care would extend to the human rights impacts of all entities in the enterprise, including subsidiaries. A company would not be liable for breach of the duty of care if it proves that it reasonably exercised due diligence as set forth in the Guiding Principles on Business and Human Rights. On the other hand, a company’s failure to exercise due diligence would create a rebuttable presumption of causation and hence liability. A company could then avoid liability only by carrying its burden to prove that the risk of the human rights violations was not reasonably foreseeable, or that the damages would have resulted even if the company had exercised due diligence.

In June 2014, the Human Rights Council passed a resolution establishing an inter-governmental working group to discuss a legally binding instrument relating to transnational corporations and other business enterprises. In this article, I outline four arguments for why such an instrument is desirable. Identifying the purpose of such a treaty is crucial in outlining a vision of what it should seek to achieve and in determining its content. The arguments indicate that a treaty is necessary to provide legal solutions to cure serious lacunae and ambiguities in the current framework of international law which have a serious negative impact upon the rights of individuals affected by corporate activities. The emphasis throughout is upon why a binding legal instrument is important, as opposed to softer forms of regulation such as the United Nations Guiding Principles on Business and Human Rights. The four arguments in turn provide the resources to respond to objections raised against the treaty and to reject an alternative, more restrictive proposal for a treaty that only addresses ‘gross’ human rights violations.

The business and human rights debate has essentially bypassed the media industry. This article addresses that gap in the debate by applying the Guiding Principles on Business and Human Rights to the media. Application of human rights responsibilities to the media in accordance with the Guiding Principles is significantly complicated by the existence of media rights of freedom of expression. It is argued that the application of the Guiding Principles to the media industry leaves significant scope for it to be involved with serious and systemic human rights violations. This conclusion indicates that the Guiding Principles are an inadequately theorised tool for dealing with human rights responsibilities of the media. It may reveal deeper flaws in the Guiding Principles, which extend to industries other than the media. At the least, a dialogue between the human rights community and the media industry must commence in order to work out how human rights might apply in the context of the responsibilities of one of the world’s most important and powerful industries.

The claim that corporations have human rights obligations remains contentious and can be fraught with confusion. This article synthesizes existing corporate human rights theory and responds to objections to the idea that transnational corporations (TNCs) have human rights obligations. The argument proceeds in three stages. The first section describes the different forms TNCs take and explains why TNCs are properly understood as moral agents responsible for their policies and practices. The second section reviews and explains different philosophical theories of corporate human rights obligations. The third section articulates and responds to objections to the idea that corporations have human rights obligations. The main conclusion of this article is that there are multiple, compelling and overlapping justifications of corporate human rights obligations.

In the last several decades a diverse movement has emerged that seeks to extend the accountability for human rights beyond governments and states, to businesses. Though the view that business has human rights responsibilities has attracted a great deal of positive attention, this view continues to face many reservations and unresolved questions.

Business ethicists have responded in a twofold manner. First, they have tried to formulate the general terms or frameworks within which the discussion might best proceed. Second, they have sought to answer several questions that these different frameworks pose: A. What are human rights and how justify one’s defence of them?; B. Who is responsible for human rights? What justifies their extension to business?; and C. What are the general features of business’s human rights responsibilities? Are they mandatory or voluntary? How are the specific human rights responsibilities of business to be determined?

Within the limited space of this article, this article seeks to critically examine where the discussion of these issues presently stands and what has been the contribution of business ethicists.
