In The South Saskatchewan Comm. Fdn., Inc. v. United States, ___ Fed. Cl. ___ (8/25/26) (“South Saskatchewan”), CFC here, TN here, and GS here [to come], the Court rejected a Canadian charity’s attempt to apply an exemption in the United States-Canada Convention with Respect to Taxes on Income and on Capital (including a key Protocol). I found South Saskatchewan interesting because of the CFC’s application of interpretive techniques to resolve the treaty dispute between the parties in a situation where the Canadian tax authority and the U.S. did not agree on the interpretation as applied to the facts.
South Saskatchewan starts with the goal of treaty interpretation being to effectuate the shared understanding of the parties to the treaty. This is the contract model of interpretation. But, in this case, Canada’s understanding of the treaty is not the U.S.’s understanding. I infer that, assuming Canada’s current interpretation was taken in good faith, Canada did not have a shared understanding with the U.S. What does a court do when it cannot discern a shared understanding?
South Saskatchewan says (Slip Op. 6) after citing Loper Bright:
The meaning of both U.S. and Canadian laws, as well as that of the Tax Treaty, is susceptible to being construed, interpreted, and applied using traditional methods of statutory interpretation.
I am not sure how traditional methods of statutory interpretation flange with the goal of interpreting treaties to apply the shared understanding of the parties. Since, for U.S. purposes, the treaty is the law of the land and the treaty is text, I guess it is close enough to written law (statutes) that the interpretive model for statutes can apply. Maybe.
The Court adopts the U.S. interpretation based on a textualist reading of the Treaty Protocol. The Court finds helpful “extrinsic evidence” in the “legislative history” [caveat, legislative history is my term not the Court’s] of the Senate’s ratification of the Protocol. This legislative history is (i) the Treasury Technical Explanation accompanying the submission of the Protocol to the Senate for approval and (ii) the Joint Committee on Taxation (“JCT”) Report which “reflects the contemporaneous understanding of the Senate that ratified the Fifth Protocol.” (Slip Op. 9.) Both documents informed the Senate of the meaning of the Protocol.
