OPINION
¶ 1 We granted review to determine whether an appellee, in an appeal from an order granting the appellee a new trial, must file a protective cross-appeal if it wishes to preserve its ability to challenge the underlying judgment, in the event the appellate court overturns the order granting a new trial. We hold that an order granting a new trial vacates the original entry of judgment and that an appellee need not challenge the underlying judgment through a mandatory protective cross-appeal.
I.
¶ 2 The Nielsons obtained a $2 million jury verdict against the Smiths. On August 10, 2000, the trial court entered judgment for the *531 Nielsons in the amount awarded. Thereafter, the Smiths moved for a new trial. The trial court granted the motion, vacated the judgment and set a new trial. The Nielsons filed a timely notice of appeal from the order granting a new trial. The Smiths did not file a cross-appeal from the underlying judgment.
¶ 3 In a memorandum decision, the court of appeals reversed the trial court’s order granting a new trial and instructed the trial court to reinstate judgment in favor of the Nielsons. After we denied the Smiths’ petition for review, the court of appeals issued its mandate on June 11, 2002, and the trial court reinstated the original judgment.
¶4 On July 3, 2002, the Smiths filed a notice of appeal from the underlying August 10, 2000 judgment. The Nielsons moved to dismiss the appeal, arguing that under Rule 9(b), Arizona Rules of Civil Appellate Procedure, the Smiths’ failure to challenge the original judgment by filing a protective cross-appeal to the Nielsons’ appeal from the order granting a new trial barred the Smiths from now challenging the underlying judgment. The court of appeals denied the Nielsons’ motion, finding nothing in Arizona law that required the Smiths to file a mandatory protective cross-appeal. We granted review to consider this procedural question of statewide importance. We exercise jurisdiction pursuant to Article VI, Section 5.4 of the Arizona Constitution and Rule 3(b) of the Arizona Rules of Procedure for Special Actions.

¶ 5 We review issues of law
de novo. US West Communications, Inc. v. Ariz. Corp. Comm’n,
¶ 6 According to the Nielsons, the court of appeals lacks jurisdiction to hear the Smiths’ appeal because the Smiths failed to file a timely appeal from the judgment entered against them. That is, they argue, the thirty day limit of Rule 9 began to run on August 10, 2000, when the trial court entered the original judgment, even though the court later vacated the judgment and ordered a new trial. Unfortunately, neither Arizona’s procedural rules nor our case law clearly answers the question whether the Smiths timely filed their appeal.
¶ 7 Rule 9, 1 on which the Nielsons primarily rely, does not answer the question posed here. That rule sets forth the time period required to file an appeal or cross-appeal after entry of judgment. Rule 9(b)(4) extends the time for filing an appeal if a party timely files certain motions, including a motion for a new trial. Nothing in the rule speaks directly to a party’s obligation to file a cross-appeal to an appeal taken from a trial *532 court’s order granting a motion for a new trial.
¶ 8 Nor does Rule 13(b) 2 provide guidance. Although an appellee’s brief to the appellate court may include “any issue properly presented in the superior court,” Rule 13(b) does not explain whether an appellee must file a compulsory cross-appeal under the circumstances involved here. Ariz. R. Civ.App. P. 13(b).
¶ 9 We also find no clear answer in Arizona ease law. Both the Nielsons and the Smiths rely upon decisions that have little relevance to the issue before us.

One opinion of this court, not referred to by either party, lends some support to the Nielsons’ position. In
Blakely Oil, Inc. v. Wells Trackways, Ltd.,
¶ 10 In addition, the plaintiffs in
Blakely Oil
were “aggrieved parties” as to that portion of the trial court’s order that denied their motion for JNOV. The Smiths, in contrast, found themselves appellees in a challenge to an order decided entirely in their favor. A second Arizona appellate decision,
Aegerter v. Duncan,
directly addresses the right of a party not aggrieved by a decision to file a cross-appeal.
¶ 11 The Nielsons seek to bolster their argument by pointing to other jurisdictions, particularly California, Florida and Oregon, that require protective cross-appeals. Courts in both California and Oregon long have required protective cross-appeals in scenarios similar to that involved here.
See Puckhaber v. Henry,
¶ 12 Because litigants have no definitive rule or decision of this court on which to rely, we next consider the policy reasons underlying our decision as to whether we should regard protective cross-appeals as mandatory. Our resolution of this issue largely turns upon whether we interpret the effect of the trial court’s order granting a new trial as vacating or merely suspending the original judgment. A vacated judgment lacks force or effect and places parties in the position they occupied before entry of the judgment.
Illinois v. Eidel,
¶ 13 Moreover, when a rule of procedure does not speak to a set of facts or speaks ambiguously, courts should give the rule a liberal construction rather than create a pitfall for the unwary.
See, e.g., Witt v. Merrill et ux.,
¶ 14 We are also concerned with the effect of our decision on judicial economy. Both parties argue that their position better promotes judicial economy. In reality, neither approach assures economy of effort. In this case, had the court of appeals affirmed the order granting a new trial, neither party would have invested time and expense in briefing and arguing issues related to the underlying judgment. Under that circumstance, then, economy would result from avoiding the cross-appeal issues. On the other hand, if, as happened here, the court of appeals reverses an order granting a new *534 trial, requiring a protective cross-appeal would have served the goal of judicial economy. The economy produced for the judicial system thus depends upon the outcome of the appeal from the. order granting a new trial. 5
¶ 15 Requiring a protective cross-appeal, however, affects entities other than the judicial system. If an appellee were required to appeal from the original judgment and that appeal turned out to be unnecessary, not only judicial resources but also attorney time and resources would be wasted. Moreover, the impact of an unnecessary appeal falls most heavily not on lawyers or the court but upon those clients who incur unnecessary expense. Given the close nature of the issue before us, we conclude that the best policy is to adopt the approach more likely to protect litigants from unnecessary expenditures. Therefore, we hold that in the situation presented by this action, an appellee need not file a protective cross-appeal. The time to appeal the underlying judgment will run from the date the judgment is reinstated.
III.
¶ 16 For the foregoing reasons, we affirm the order of the court of appeals denying the Nielsons’ motion to dismiss the Smiths’ appeal. We also vacate our October 29, 2002 order staying all further proceedings in the court of appeals.
Notes
. Rule 9 provides in part:
Rule 9. Appeal — When Taken
(a) Time; Personal Representatives; Cross-Appeal. A notice of appeal required by Rule 8 shall be filed with the clerk of the superior court not later than 30 days after the entry of the judgment from which the appeal is taken, unless a different time is provided by law____ A notice of cross-appeal may be filed by an opposing parly within 20 days from the date the notice of appeal is filed.
(b) Extension of Appeal Time. When any of the following motions are timely filed by any party, the time for appeal for all parties is extended, and the times set forth in Rule 9(a) shall be computed from the entry of any of the following orders:
(1) Granting or denying a motion for judgment notwithstanding the verdict pursuant to Ariz. Rules Civ. Proc. 50(b);
(2) Granting or denying a motion to amend or make additional findings of fact pursuant to Ariz. Rules Civ. Proc. 52(b), whether or not granting the motion would alter the judgment;
(3) Granting or denying a motion to alter or amend the judgment pursuant to Ariz. Rules Civ. Proc. 59(1);
(4) Denying a motion for new trial pursuant to Ariz. Rules Civ. Proc. 59(a).
Ariz. R. Civ.App. P. 9.
. Rule 13(b) provides:
(b) Brief of the Appellee. 1. The brief of the appellee shall conform to the requirements of the preceding subdivision, except that a statement of the case, a statement of the facts or a statement of the issues need not be included unless the appellee finds the statements of the appellant to be insufficient or incorrect.
2. If a cross-appeal has been filed, the brief of the appellee or the opening brief of the cross-appellant shall include in its statement of issues presented for review the issues presented in the cross-appeal.
3. The brief of the appellee may, without need for a cross-appeal, include in the statement of issues presented for review and in the argument any issue properly presented in the superior court. The appellate court may affirm the judgment based on any such grounds. The appellate court may direct that the judgment be modified to enlarge the rights of the appellee or to lessen the rights of the appellant only if the appellee'has cross-appealed seeking such relief.
Ariz. R. Civ.App. P. 13(b).
. In
Arizona-Parral Mining Co. v. Forbes,
we referred to language in an Indiana Supreme Court case supporting the proposition that, following a
final judgment,
a party must consolidate all appealable issues in its appeal.
In
Hawkins v. Allstate Ins. Co.,
we admonished a party for raising a constitutional issue for the first time on appeal.
. The Arizona Rules of Civil Procedure now refer to a motion for JNOV as a renewed "motion for a judgment as a matter of law.” Ariz. R. Civ. P. 50(b).
. An appellate decision reversing an order granting a new trial is less likely than a decision upholding such an order. An appellate court can reverse an order granting a new trial only upon a showing of abuse of discretion.
