The company behind the Keystone XL oil pipeline says it is taking legal action against the Obama administration’s rejection of the project.
The Calgary-based TransCanada Corporation says it intends to launch a claim under a section of the North American Free Trade Agreement, as well as sue on the grounds the president “exceeded” his power under the constitution.
The pipeline would have transported tarsands crude from Alberta to the Texas Gulf Coast.
President Barack Obama rejected the project in November, saying it would not serve the national interests of the United States.
The company alleges the denial was “arbitrary and unjustified.”
TransCanada is seeking to recover more than $15 billion in costs and damages.
