(AP) — The trial of a lawsuit filed by Nebraska landowners challenging Gov. Dave Heineman’s decision to approve a new route for the proposed Keystone XL pipeline through the state will be held Friday afternoon in Lincoln.

In June, a Lancaster County District judge rejected a motion by state officials to dismiss the lawsuit, filed by three Nebraska landowners. They say a law passed during a special legislative session in 2011 as a way to reroute the pipeline away from Nebraska’s environmentally sensitive Sandhills was unconstitutional.

The landowners say the law doesn’t allow for judicial review and doesn’t spell out what criteria should be considered when a pipeline project is being evaluated.

Those who favor the pipeline have cited the nation’s need for more oil and praised its potential economic impact.
