A Nebraska county judge struck down a law that would allow the controversial Keystone XL pipeline to run through the state.
The ruling may cause further delay in the process leading to a decision on the TransCanada pipeline, which would carry crude from Alberta to Gulf of Mexico refineries.
Tension over President Obama's final decision on Keystone XL has increased since the State Department released its final environmental review of the project.
It's a win for pipeline opponents such as the coalition Bold Nebraska, which argued Heineman overstepped his authority when approving the route for the $5.4 billion project early last year.
