In Arizona State Highway Commission v. Superior Court, 81 Ariz. 74, 299 P.2d 783 (1956) the Arizona Legislature empowered the highway commission to determine the placement of school crossings. Id. at 75, 299 P.2d at 783. A party challenged the agency's application of that discretion in the placement of a particular school zone and crosswalk. The Arizona Supreme Court held that a court cannot require an agency to exercise its legislatively conferred discretion in any particular manner, but can require that it not abuse that discretion. Id. at 77, 299 P.2d at 785.
