OPINION
¶ 1 We granted review in this case to determine whether we should continue to follow the rule that a party seeking to obtain relief from a judgment entered after remand from an appellate court must first apply to the appellate court for permission to pursue its motion in the trial court. We conclude that we should not continue to follow that rule and therefore overrule
Rogers v. Ogg,
FACTS AND PROCEDURAL HISTORY
¶ 2 In September 1996, U S West Communications brought an action in tax court
1
against the Arizona Department of Revenue and all fifteen Arizona counties (collectively the Department) challenging the 1996 valuation for ad valorem tax purposes of some of U S West’s property. In that action, U S West challenged the Department’s interpretation of the pertinent statutes, alleging the Department incorrectly determined the Class 3 value of its property and that as applied by the Department, the statute resulted in a discriminatory tax. U S West moved for and obtained summary judgment, and the Department’s cross-motion for summary judgment was denied. On appeal, however, the court of appeals held that the Department properly interpreted and applied the statutes, rejected U S West’s constitutional challenge to those statutes, and ordered that judgment be entered in favor of the Department.
U S West Communications, Inc. v. Arizona Dep’t of Revenue,
¶ 3 Some months later, U S West filed a timely motion under Rule 60(c), Ariz.R.Civ. P., to set aside the judgment, arguing that the Department deprived it of its “day in court” and its opportunity to present evidence of de facto discrimination. Claiming excusable neglect, U S West argued that Rule 60(c)(1) provided a basis for relief for its failure to present the evidence because the trial judge’s grant of summary judgment precluded it from doing so. It also argued that it was entitled to relief under Rule 60(c)(2) because of newly discovered evidence that its competitors were receiving disparate and more favorable treatment from the Department. Finally, U S West sought alternative relief under the catch-all provision of Rule 60(c)(6).
¶ 4 Because the court of appeals’ mandate had issued,
Rogers
required that U S West first seek permission from that court to file
*103
its Rule 60(c) motion in the tax court.
See Rogers,
¶5 We granted U S West’s petition for review to examine whether we should continue to follow the Rogers rule in light of developments since it was articulated in 1966. We note that the Rogers rule has no basis in the text of the rules and conclude we should not continue to follow our previous cases on the subject.
DISCUSSION
¶ 6 In
Rogers,
we held that a motion for relief from a judgment on the grounds of newly discovered evidence and fraud could not be filed in the trial court after the case had been appealed and decided by this court. We required, instead, that a litigant seeking relief from a judgment entered pursuant to an appellate court mandate must first obtain permission from the appellate court. This rule was necessary, we said, because a lower court was without power “to disturb the judgment without leave of the appellate court” that had ordered its entry.
Rogers,
¶ 7 Ten years after we decided
Rogers,
the United States Supreme Court abandoned the rule requiring appellate leave prior to seeking relief from a judgment entered pursuant to an appellate court mandate.
See Standard Oil Co. v. United States,
¶ 8 We believe the points made by the United States Supreme Court are persuasive. 2 Of course, questions arise, as they *104 may have in this case, whether certain issues were settled on appeal, whether motions were properly documented or supported, or whether evidence was truly newly discovered, but we believe trial judges are better equipped to resolve these and similar problems than appellate courts.
¶ 9 For obvious jurisprudential reasons, we are quite reluctant to overrule our past decisions but more willing to do so on procedural matters than on substantive issues.
State v. Salazar,
¶ 10 In the present case, we deal with a procedural matter. While we are not required to follow United States Supreme Court' decisions on non-federal issues, procedural uniformity is a desirable and important objective, absent serious disagreement with that Court’s reasoning.
See Orme School v. Reeves,
CONCLUSION
¶ 11 We believe the reasoning of Standard Oil is compelling and therefore adopt the rule followed in that case. We thus overrule Rogers v. Ogg 3 insofar as it deals with the present issue and hold that relief under Rule 60 from a judgment entered pursuant to an appellate court mandate may be sought without first obtaining permission from the appellate court and without first seeking recall of the mandate. In this and future cases, trial courts may entertain Rule 60 motions and take appropriate action without leave from an appellate court. In the present case, therefore, the motion for permission to file is denied as unnecessary, and the trial judge is directed to proceed as he deems appropriate with U S West’s pending motions for relief from or modification of the judgment. Of course, we express no opinion on the propriety of granting or denying relief.
Notes
. The tax court, a department of the Superior Court in Maricopa County, is established by A.R.S. § 12-161 (1992) as the trial court that exercises original jurisdiction over cases involving the legality of any tax, impost, or assessment.
. Shortly after Butcher & Sherrerd was decided, the Advisory Committee on Rules for Civil Procedure issued a proposed amendment to Rule 60, Fed.R.Civ.P., that would have removed the requirement of seeking leave from the appellate court. 12A Charles Alan Wright, Arthur P. Miller, Mary Kay Kane and Richard L. Marcus, Federal Practice & Procedure App. F, at 769 (1955 Report of the Advisory Committee, Proposed Amendments to the Rules of Civil Procedure for the United States District Courts) (2000). In its note supporting the amendment, the Advisory Committee stated that:
An appellate court cannot know whether the requirements for reopening a case ... are actually met without a full record which must *104 obviously be made in the district court. The amendment expressly negates any such barren requirement.
Id. at 770. The proposed amendment was not made, but Standard Oil obviated the need by removing the leave requirement.
. We also disapprove the pertinent portions of cases decided by this court and the court of appeals on the authority of
Rogers. See, e.g., Peabody Coal Co. v. Navajo County,
