TransCanada v. USA

In January 2016, Transcanada Corporation filed a request for arbitration arising out of the denial of the application for a Presidential Permit to construct the Keystone XL Pipeline, a proposed 1,897 km crude oil pipeline from Alberta (Canada) to Nebraska (United States), and the Government’s actions leading to that denial. The company argued that due to the "politicization" of the Obama administration's decision on whether to award a Presidential Permit for the Keystone XL Pipeline the US government was in breach of NAFTA provision regarding national treatment, most-favoured nation treatment and minimum standards of treatment, and that its actions amounted to an expropriation of property for which the company was entitled to compensation. The case was subsequently discontinued after the Trump administration's reversal of the decision to deny the Presidential Permit.
