A/HRC/17/31 the duty to protect against human rights abuse by third parties, including business enterprises. The State duty to protect is a standard of conduct. Therefore, States are not per se responsible for human rights abuse by private actors. However, States may breach their international human rights law obligations where such abuse can be attributed to them, or where they fail to take appropriate steps to prevent, investigate, punish and redress private actors’ abuse. While States generally have discretion in deciding upon these steps, they should consider the full range of permissible preventative and remedial measures, including policies, legislation, regulations and adjudication. States also have the duty to protect and promote the rule of law, including by taking measures to ensure equality before the law, fairness in its application, and by providing for adequate accountability, legal certainty, and procedural and legal transparency. This chapter focuses on preventative measures while Chapter III outlines remedial measures. 2. States should set out clearly the expectation that all business enterprises domiciled in their territory and/or jurisdiction respect human rights throughout their operations. Commentary At present States are not generally required under international human rights law to regulate the extraterritorial activities of businesses domiciled in their territory and/or jurisdiction. Nor are they generally prohibited from doing so, provided there is a recognized jurisdictional basis. Within these parameters some human rights treaty bodies recommend that home States take steps to prevent abuse abroad by business enterprises within their jurisdiction. There are strong policy reasons for home States to set out clearly the expectation that businesses respect human rights abroad, especially where the State itself is involved in or supports those businesses. The reasons include ensuring predictability for business enterprises by providing coherent and consistent messages, and preserving the State’s own reputation. States have adopted a range of approaches in this regard. Some are domestic measures with extraterritorial implications. Examples include requirements on “parent” companies to report on the global operations of the entire enterprise; multilateral soft-law instruments such as the Guidelines for Multinational Enterprises of the Organization for Economic Cooperation and Development; and performance standards required by institutions that support overseas investments. Other approaches amount to direct extraterritorial legislation and enforcement. This includes criminal regimes that allow for prosecutions based on the nationality of the perpetrator no matter where the offence occurs. Various factors may contribute to the perceived and actual reasonableness of States’ actions, for example whether they are grounded in multilateral agreement. 7
