LINCOLN, Neb. (AP) — Nebraska landowners who oppose the Keystone XL pipeline are still trying to overturn a law that allowed the governor to approve the project.

That’s despite the fact that pipeline developer TransCanada is no longer relying on it.

Pipeline opponents said Monday they’re concerned that companies could use the law in the future to avoid a state commission that regulates pipelines, opting instead for a governor’s review and blessing.

Former Gov. Dave Heineman approved a Nebraska route for the Keystone XL in 2013. But the 2012 law which gave him that power is mired in court, preventing the project from moving forward.

TransCanada says it withdrew its eminent domain claims against landowners and reapplied to the commission. Spokesman Mark Cooper says the company now believes there’s no case to continue challenging the pipeline-siting law.
