STUDY LABOUR AND SOCIAL JUSTICE COMPANIES AND HUMAN RIGHTS A Global Comparison of Legal Due Diligence Obligations Robert Grabosch April 2020 This study illustrates many countries have unilaterally de­veloped varying theories in sup­port of their efforts to regulate corporate due diligence in hu­man rights. Most of those the­ories have been limited to the­matic or regional approaches. Many of the laws have ex­traterritorial effects. These laws apply to foreign compa­nies doing business in their country, own a branch or sub­sidiary in their country or are listed on their country’s do­mestic stock exchange. Civil society and labor unions exert influence on the devel­opment of regulatory require­ments. Whenever legislation was passed without consider­ing the interests of these par­ties, doubts have arisen and many questions remain.
