The lobbying group representing the oil industry wants to see the rule of law upheld in a court case over the future of a controversial pipeline in North Dakota.

Speaking to reporters on Wednesday, Robin Rorick, director of the American Petroleum Institute’s midstream group, that oversees transportation issues, said construction on the Dakota Access oil pipeline should be allowed to continue. Rorick said the pipeline went through the proper permitting process, which he described as “open and transparent.”
