TransCanada Corp.’s Keystone XL Pipeline faces one less hurdle after Nebraska’s highest court cleared its path through the state, setting aside a challenge to the power of its Republican governor to dictate the route, and sending the matter back to Washington.

The project would send crude from Alberta’s oil sands to a network junction in southeast Nebraska, for transport to Gulf Coast refineries. While the ruling is a victory for energy independence proponents, the project’s fate remains uncertain. It now returns to President Barack Obama for approval, who deferred a decision citing the lawsuit.

The U.S. Senate Energy Committee Jan. 8 passed a measure by a vote of 13-9 forcing approval of the pipeline, setting up a confrontation with Obama, who has pledged to veto the legislation.

The full chamber is to take up the issue next week, Republican Majority Leader Mitch McConnell of Kentucky said. A final Senate vote isn’t expected until later this month. The House is scheduled to vote today on similar legislation.

Democrats in both chambers say they have the votes to sustain a veto, though Keystone supporters say they are still trying to persuade colleagues.

The Obama administration had suspended a State Department review of the international pipeline while the Nebraska case was pending.
