African Investment Disputes

In the early days of investment treaty awards, twenty or so years ago, it was obvious something was badly amiss. With virtually no legal analysis, the Metalclad tribunal found an indirect expropriation against Mexico based on the government’s refusal to authorize a landfill in a historically polluted area. A few years later, foreign asset owners busily sued Argentina for the country’s emergency measures, adopted in the face of a national economic crisis; the arbitrators were unsympathetic to the Argentine lawyers’ argument that it was ‘necessary’ for the country’s government to override the stipulated water rates in contracts with irresponsibly privatized utilities so households could afford drinking and bathing during the crisis and recovery. In CME, a case against the Czech Republic, the tribunal awarded hundreds of millions to a U.S. mogul after reasoning very erratically that the country had violated most of the cryptic investor protections in the invoked treaty. The dispute arose from Czech efforts to regulate broadcasting of cheap American re-runs on a major privatize TV station that was filling the airwaves with profitable muck. A sister tribunal in Lauder, bizarrely hearing a parallel claim by the human owner of the CME company, refused to award any compensation for the same dispute.

A fundamental premise of The Investment Treaty Regime and Public Interest Regulation in Africa is that national constitutions “are supreme in the hierarchy of legal norms within the domestic context, and governmental actions in Africa, including the making of investment treaties, are governed by these fundamental legal norms.” In this monograph, I addressed, then, the question of the limits that national constitutions and the right of African states to regulate in international law place on the authority of African states in their conclusion of international economic treaties such as investment treaties. I examined four different and fundamental areas of public interest: national judicial systems, the environment, human rights, and development. Based on a constitutional-general international law imperatives analysis, I developed the imperatives theory as a theoretical framework to explain the conflict of legal norms and interests through a critical analysis of the intersections of public law and policy and international investment treaties. The issue addressed by the imperatives theory is whether the fundamental human rights and corresponding obligations of African states towards citizens under African constitutions, international environmental treaties and international human rights treaties do place or should place, limitations on the competence of African states to conclude investment treaties the terms of which constrain the exercise of the states’ public interest regulatory authority.
