Opponents of TransCanada Corp.‘s proposed northern portion of the Keystone XL oil pipeline from Canada running through parts of Nebraska argued last Thursday in state district court in Lancaster County that Nebraska Gov. Dave Heineman lacked the authority to approve a proposed route for the project. In January, he approved a new alternative route (see Shale Daily, Jan. 23). Opponents of the project want Heineman’s decision voided by a district court judge because they allege a state pipeline siting act passed last year by Nebraska’s legislature is unconstitutional. The legislation gave the governor the ultimate decision on the route. At the end of last year Lancaster County District Judge Stephanie Stacy rejected the state’s attempt to have the lawsuit dismissed.
