Fair and equitable treatment provisions are found in almost all bilateral and multilateral investment treaties and many international investment agreements. Throughout the course of the last decade, this treatment standard has been frequently invoked in investor-State arbitrations. Under its aegis, tribunals have developed a number of vaguely defined sub-categories, or what have been referred to as ‘facets’ or ‘components’ of the standard, such as the obligation of the State to refrain from acting in an arbitrary manner, to afford justice and due process to foreign investors, to act transparently, and to respect the legitimate expectations of the investor (see comment entitled ‘Fools Gold? Legitimate Expectations as Understood in Glamis Gold v USA‘). Despite such attention, the precise application of and relationship between these components remains vague and elusive.
The task of interpreting and applying fair and equitable treatment was made more complex by the following series of events.
In 1999, an American investor brought a claim under NAFTA‘s investor protection provisions. The investor alleged, inter alia, that Canada’s regulations with respect to the importation of softwood lumber violated Article 1105 of NAFTA. Article 1105(1) provides that ‘Each Party shall accord to investments of investors of another Party treatment in accordance with international law, including fair and equitable treatment and full protection and security.’ At the time of the arbitration, trends in the decisions of arbitral tribunals favoured interpreting fair and equitable treatment provisions as either an autonomous treaty provision or a standalone principle found in customary international law. The tribunal favoured the former, finding for the investor, but leaving the question of damages to be assessed at later date by a new tribunal.
Following the decision, and in a dramatic twist, the NAFTA parties issued a joint interpretive note clarifying their view of both Article 1105, and fair and equitable treatment and full protection and security. The note read as follows:
