The Iowa Utilities Board denied Thursday a request by a group of landowners to halt construction of the Dakota Access Pipeline. The Board voted against a lengthy stay of construction on parcels of land for 14 landowners while a court considers a lawsuit that they have filed.

The suit challenges the boards’ authority to allow eminent domain for a privately owned pipeline project. The landowners were told that they would not likely be successful in there court case and that Dakota Access would be financially harmed by construction delays.

Construction on the pipeline at the site in Southern North Dakota near the Standing Rock Indian Reservation has not resumed after a protest in opposition to the pipeline. The pipeline company agreed to halt construction near the reservation until a hearing next week in federal court.

The Iowa landowners plan to appeal the decision in district court and hope to delay construction until a court can hear their legal challenge to the project.
