The city of Williston enacted two ordinances that would ban man camps within its city limits. Target Logistics and Halliburton sued in federal court. They said, among other things, that Williston was discriminated unconstitutionally against out-of-state people and companies, favoring its own local people. Later, Weatherford joined the suit.
Now, Target Logistics and Halliburton are dismissed out of the case, but Weatherford is pressing on.
