The Cooperatives assert that because these provisions were invalid, nothing remained to remand. ¶ 139 The Cooperatives cite Carondelet Health Servs., Inc. v. Arizona Health Care Cost Containment Sys. Admin., 182 Ariz. 221, 895 P.2d 133 (App.1994), and Cochise County v. Arizona Health Care Cost Containment Sys., 170 Ariz. 443, 825 P.2d 968 (App.1991), to support their contention. But neither ease addressed whether an agency decision adopting rules could be reversed and remanded for compliance with the APA. Rather, each case voided actions taken pursuant to invalid rules.
