In Am. Credit Bureau v. Pima County, 122 Ariz. 545, 546-47, 596 P.2d 380, 381-82 (App. 1979), appellants timely appealed from a post-judgment order denying a motion to vacate a monetary judgment which motion claimed in part that the superior court lacked jurisdiction of the entire matter because no claim had been filed against the County. The Court held that the court's earlier Ariz. R. Civ. P. 54(b) judgment on the power of the county sheriff was void so it could be attacked later in the post-judgment motion, there was still a timely appeal from the order seeking to attack the entire basis of the final judgment.
