In case of condemnation to secure any real estate, rights, or interests authorized under this chapter, the court actions shall be brought in the name of the state of Washington in the respective counties in which the real estate is located and in the manner provided by law for acquiring property for public uses for the state. In such actions the selection of the real estate, rights, and interests by the department is, in the absence of bad faith, arbitrary, capricious, or fraudulent action, conclusive upon the court and judge before which the action is brought that the real estate, rights, and interests are necessary for public use for the purposes sought.
