Case Overview
The case, *William Clayton et al. v. Canada*, is an investor-state arbitration brought by U.S. investors (the Clayton family and their company, Bilcon of Delaware) against the Government of Canada. The dispute arises under Chapter 11 of the North American Free Trade Agreement (NAFTA). The arbitration is administered by the Permanent Court of Arbitration (PCA) under the UNCITRAL Arbitration Rules. The dispute concerns the Claimants' investment in a proposed basalt quarry and marine terminal project at Whites Point, Nova Scotia, which was ultimately rejected by Canadian environmental authorities following a joint federal-provincial environmental assessment.
Procedural History
The Claimants issued a Notice of Arbitration on May 26, 2008. The Tribunal, composed of Bruno Simma (President), Bryan Schwartz (appointed by the Claimants), and Donald McRae (appointed by Canada), rendered a 2-1 Award on Jurisdiction and Liability on March 17, 2015. The majority found Canada liable for breaches of NAFTA, while Professor McRae dissented. Following the award, Canada applied to the Federal Court of Canada to have the liability award set aside on jurisdictional grounds. On May 2, 2018, the Federal Court dismissed Canada's application, upholding the award. The arbitration then proceeded to the quantum phase to determine damages.
Key Issues and Positions
Arbitration (Merits)
The Claimants alleged that the environmental assessment process for their project was manipulated, lacked due process, and was arbitrary and discriminatory. They argued that the Joint Review Panel (JRP) improperly departed from its mandate under Canadian environmental law by basing its negative recommendation on a vague and previously unannounced standard of "community core values." This conduct, they claimed, breached Canada's obligations under NAFTA Articles 1105 (minimum standard of treatment), 1102 (national treatment), and 1103 (most-favoured-nation treatment). Canada defended the JRP's process as being consistent with its mandate and domestic law, arguing that the panel's conclusions were reasonable and non-discriminatory.
Set-Aside Application
Before the Federal Court of Canada, the key issue was the scope of the NAFTA Tribunal's jurisdiction. Canada argued that the Tribunal majority exceeded its jurisdiction by grounding its liability finding in a perceived breach of Canadian domestic administrative and environmental law, rather than applying the distinct, high-threshold standard of customary international law required by NAFTA. Canada contended that the Tribunal had wrongfully acted as a court of appeal for a domestic regulatory decision. The investors countered that the Tribunal had acted squarely within its mandate to decide NAFTA claims, and that its consideration of Canadian law was an essential and permissible part of the factual analysis required to determine whether Canada's conduct was arbitrary and breached international law standards.
Tribunal/Court Reasoning and Holdings
Merits (NAFTA Tribunal Award)
A majority of the Tribunal (President Simma and Arbitrator Schwartz) found that Canada had breached its obligations under NAFTA Article 1105 (Minimum Standard of Treatment) and Article 1102 (National Treatment). The majority held that the JRP's reliance on the concept of "community core values" constituted a "fundamental departure from the methodology required by Canadian and Nova Scotia law" and amounted to the creation of a new standard of assessment without notice to the investor. This conduct was deemed arbitrary and unjust, frustrating the investor's legitimate expectations and rising to the level of a breach of the international minimum standard. The finding of a breach of national treatment was based on the conclusion that the investors "did not receive the expected and legally mandated application" of the environmental assessment standards that would be applied to a Canadian proponent. Professor McRae dissented, arguing that the JRP had acted within its legal mandate and that the majority had erred by equating a potential breach of domestic law with a breach of NAFTA's international law standard.
Set-Aside (Federal Court of Canada)
The Federal Court of Canada dismissed Canada's application to set aside the award. The Court held that the Tribunal had not committed a jurisdictional error. It reasoned that the central issue decided by the Tribunal—whether Canada's conduct breached its NAFTA obligations—was squarely within the scope of the submission to arbitration. The Court found that the Tribunal's analysis of Canadian domestic law was an incidental and necessary part of its assessment of the factual matrix, undertaken to determine whether the conduct met the international law threshold for a treaty breach. The Court characterized Canada's arguments as a challenge to the merits of the Tribunal's decision—its findings of fact and its application of law to those facts—which are not reviewable grounds for setting aside an award under Canada's *Commercial Arbitration Act*.
Disposition / Relief
The NAFTA Tribunal found Canada liable for breaches of its treaty obligations, with the quantum of damages to be determined in a subsequent phase. The Federal Court of Canada dismissed Canada's application to set aside the liability award, with costs awarded to the investors.
