1. A writ of prohibition is a preventive remedy not available to correct errors or reverse illegal proceedings. Huhn v. Foley Bros. Inc.
2. In effect, the district court has ordered a judgment which directs the commission to enter an order determining that certain actions of the Black and White Duluth Cab Company are violations of law and to issue a cease and desist order against that company as to such violations. This the court may not do. It exhausts its powers when it determines whether the commission's orders are unreasonable or arbitrary. It may not go further and direct the commission as to what order it must enter and then direct it to issue a cease and desist order in furtherance of the order it assumes to direct the commission to make. Steenerson v. G. N. Ry. Co.
The court may not assume the functions of the commission. To do so would be an unconstitutional assumption of legislative powers. State v. G. N. Ry. Co.
3. Respondent takes the position that the commission is not an interested party, but when the district court on appeal from an order of the commission orders a judgment requiring the commission to do something beyond the jurisdiction of the court, the state, through the attorney general, acquires an interest sufficient to justify an application for a writ of prohibition.
