Thesis Title

Re-Defining Investor Obligations in International Investment Law: Embedding the Business and Human Rights Agenda on Mandatory Corporate Human Rights Due Diligence in the International Investment Regime

Thesis Summary

There is growing recognition of the human rights impacts of foreign investment activities on the population of capital importing countries. International investment law has been facing a legitimacy crisis, partly attributable to the lack of human rights accountability of foreign investors. The thesis analyses the notion of investor due diligence in international investment arbitration and its potential in ameliorating this accountability gap by advancing higher standards of corporate conduct with respect to human rights. The thesis draws on the business and human rights field in this regard.
