The issue in this case is whether a custodial parent can modify a grandparent visitation order on the ground that the applicable provision of the grandparent visitation statute, upon which the order was based, was subsequently found unconstitutional. The district court determined the visitation order was subject to modification, and it terminated the visitation. We agree and affirm the judgment of the district court.
I. Background Facts and Proceedings
Jim and Wanda Spiker are the grandparents of Paige and James Spiker. Paige and James are the children of Kelly Spik-er, Wanda and James’s son, and Sherry Spiker. Sherry and Kelly were divorced on August 16, 1999. Sherry was designated the primary physical caretaker of thе children, and Kelly was allowed visitation.
On February 5, 2001, Wanda and Jim filed a petition for grandparent visitation under Iowa Code section 598.35 (2001). They filed the petition after Kelly stopped visiting the children in January 2000, and Sherry stopped allowing the children to visit them. On August 21, in the course of the litigation, Wanda, Jim, and Sherry entered into a stipulation agreement providing that Wanda and Jim would be allowed visitation with the children and that they would provide transportation of the children to and from visits. However, they could not agree as to the length or time of the visitation, so they left that issue for the court to decide. Following a hearing, the court granted Wanda and Jim visitation with the children оn the first weekend of every month beginning September 2001. Sherry did not appeal.
Visitation occurred as ordered for almost a year when Sherry began withholding Paige from visits. By 2004, Sherry *351 refused to allow Wanda and Jim to visit either Paige or James.
On February 19, 2004, Wanda and Jim initiated contempt proceedings against Sherry for refusing to allow visitation with the children. The court entered an order for Sherry to show cause why she should not be held in contempt. Sherry responded that her refusal to allow visitation was “due to good cause for the children’s best interest.” She also asserted that the grandparent visitation statute was unconstitutional and that enforcement of the visitation оrder would violate her due process rights.
The court held a hearing on the issue of Sherry’s contempt on March 22, 2004. It issued an order on March 25 finding Sherry in contempt of court. The court reasoned that Sherry should have challenged the constitutionality of the visitation order at or before trial, not as a defense in contempt proceedings.
See Walker v. City of Birmingham,
Sherry filed a motion to enlarge or amend under rule 1.904(2), again arguing that enforcement of the visitation order would violate her due process right to raise her children without undue interference by the State. She contended that the order could not be enforced absent a finding that she was an unfit mother. She further argued that the stipulation agreement she entered into with Wanda and Jim was unenforceable and did not validly waive her constitutional rights. The court denied the motion. Sherry did not appeal.
On April 27, 2004, Sherry filed a petition to modify, vacate, or stay the visitation order, again arguing that the decree was unconstitutional. After Wanda and Jim filed their answer, Sherry moved for summary judgment, and Wanda and Jim resisted. On June 29, 2004, the court granted Sherry’s motion for summary judgment and vacated the visitation order. Wanda and Jim appeal.
II. Standards of Review
“[Challenges to Iowa’s grandparent visitation statute raise ‘questions of substantive due process and liberty interests in the context of statutory interpretation’ obliging us ‘to review the record de novo, making our own evaluation of the totality of the circumstances.’ ”
In re Marriage of Howard,
III. Discussion
A. Res Judicata
Wanda and Jim first argue that Sherry is barred from challenging the constitutionality of the visitation order under the doctrine of res judicata.
1
They claim Sherry should have appealed the August 21, 2001 decree granting visitation if she wanted to challenge it as unconstitutional. This argument is supported by several general principles governing res judicata, and was recently adopted by the Arkansas Supreme Court in
Hunt v. Perry,
In
Hunt v. Perry,
a grandmother sought visitation of her grandchildren from their father, her former son-in-law.
Hunt,
[T]he fact that he failed to pursue an appeal now prevents him from challenging the trial court’s previous order finding the stаtute constitutional. In sum, because we have a case that involves the same parties, the same issue, and has already been decided by a court of competent jurisdiction, the doctrine of res judicata is applicable.
Id.
at 662;
see also Ingram v. Knippers,
In deciding whether to follow this holding, we must determine whether the
Hunt
decision is consistent with our prior law concerning res judicata.
See Handeland v. Brown,
“The doctrine of res judicata embraces the concepts of claim preclusion and issue preclusion.”
Colvin v. Story County Bd. of Review,
Our law concerning claim preclusion is well established:
The general rule of claim preclusion provides a valid and final judgment on a claim precludes a second action on that claim or any part of it. The rule applies not only as to every matter which was offered and received to sustain or defeat the claim or demand, but also as to any other admissible matter which could have been offered for that purpose. Claim preclusion, as opposed to issue preclusion, may foreclose litigation of matters that have never been litigated. It does not, however, apply unless the party against whom preclusion is asserted had a “full and fair opportunity” to litigate the claim or issue in the first action. A second claim is likely to be barred by claim preclusion where the “acts complained of, and the recovery dеmanded are the same or where the same evidence will support both actions.” A plaintiff is not entitled to a second day in court by alleging a new ground of recovery for the same wrong.
Arnevik v. Univ. of Minn. Bd. of Regents,
The first element of claim preclusion is beyond dispute. Clearly, the parties in the first action (Wanda and Jim’s petition for grandparent visitation) and in the second *354 action (Sherry’s petition to modify, vacate, or stay the visitation order) are the same.
The second element is also fairly straightforward. Again, the issue is whether Sherry could have attacked the constitutionality of the grandparent visitation statute in the first action.
See Ame-vik,
The final element of claim preclusion is that “there was a final judgment on the merits in the first action.” Id.; see also Restatement (Second) of Judgments § 13, at 132 (“The rules of res judicata are applicable only when a final judgment is rendered.”). Whether the initial visitation order wаs a “final” judgment is the fighting issue in this case. Sherry contends that res judicata does not apply to orders concerning custody and visitation and that the court always has jurisdiction to modify such a decree.
There is no specific statutory authority for courts to modify grandparent visitation decrees. See Iowa Code § 598.35; id. § 598.41; see also id. § 600B.31 (stating courts in paternity actions have continuing jurisdiction in paternity actions “to determine the custody in accordance with the best interests of the child”). Nevertheless, the initial grandparent visitation order in this case was a judgment granting continuing relief. See Restatement (Second) of Judgments § 13 cmt. c, at 133 (“A judgment concluding an action is not deprived of finality for purposes of res judicata by reason of the fаct that it grants or denies continuing relief, that is, requires the defendant, or holds that the defendant may not be required, to perform acts over a period of time. Judgments of these types are rendered typically in actions for ... child support and *355 custody.”)- When judgments concerning continuing relief are involved and
a change of circumstances makes the judgment too burdensome or otherwise inapposite as a regulation of ongoing conduct, it is ordinarily possible for the party concerned to apply to the rendering court for a modification of the terms of the judgment.
Restatement (Second) of Judgments
§ 18 cmt.
c,
at 133; see
also id.
§ 73, at 197 (“Subject to the limitations stated in § 74, a judgment may be set aside or modified if: (1) The judgment was subject to modification by its own terms or by applicable law, and events have occurred subsequent to the judgment that warrant modification of the contemplated kind; or (2) There has been such a substantial change in the circumstances that giving continued effect to the judgment is unjust.”);
cf. In re Marriage of McCurnin,
In order to determine whether an order granting continuing relief has preclusive effect in a later action (i.e., is a “final judgment” for res judicata purposes), we ask “whether the issues in the two actions are materially different because of events which occurred in the interim, in which case preclusion is to be denied.”
Restatement ■ (Second) of Judgments
§ 13 cmt. c, at 134. In other words, the first judgment does not have a preclu-sive effect in the second action if circumstances have changed sufficiently to warrant -modifying the decree.
Wade v. Hirschman,
Ultimately then, the case turns on whether Sherry established a substantial change in circumstances warranting modification of the initial grandparent visitation order. In her petition to modify, the only change in circumstances Sherry alleged was that we had held some provisions of thе grandparent visitation statute unconstitutional in recent years.
See Lamberts v. Lillig,
We have held that “[t]he res judicata consequences of a final unappealed judgment are not altered by the fact that the judgment may have rested on incorrect legal principles.”
In re Bisenius,
the general principal that changes of law do not defeat claim preclusion may be relaxed when the dispute involves matters of special sensitivity. The easiest illustrations are provided by development of constitutional princiрles in cases that challenge continuing conduct of broad public importance.... A few cases reject preclusion in face of evolving constitutional law principles although the public interest may not seem as vital or the interests involved seem more nearly personal than public. These decisions are justified by many factors. The rights involved may be of public importance at an abstract level, despite the lack of obvious immediate importance. Often the first actions were eligible for preclusion only on principles of representation; special care is always required to ensure that nonpartiеs are properly bound in such cases. Finally, ordinary claim preclusion rules are often strained by continuing conduct.
18 Wright § 4415, at 372-73.
The United States Supreme Court has dealt with the issue in the context of a statutory change occurring after the original judgment. In
System Federation No. 91 v. Wright,
There is also no dispute but that a sound judicial discretion may call for the modification of the terms of an injunctive decree if the circumstances, whether of law or fact, obtaining at the time of its issuance have changed, or new ones have since arisen. The source of the power to modify is of course the fact that an injunction often requires continuing supervision by the issuing court and always a continuing willingness to apply its powers and processes on behalf of the party who obtained that equitable relief. Firmness and stability must no doubt be attributed to continuing injunc-tive relief based on adjudicated facts and law, and neither the plaintiff nor the court should be subjected to the unnecessary burden of re-establishing what has once been decided. Nevertheless the court cannot he required to disregard significant changes in law or facts if it is “satisfied that what it has been doing has been turned through changing circumstances into an instrument of wrong. ” A balance must thus be struck between the policies of res judicata and the right of the court to apply modified measures to changed circumstances.
Id.
at 647-48,
This principle applies with equal, if not greater, force to the visitation order at issue in this case. If the visitation order has turned into “an instrument of wrong,”
Sys. Fed’n No. 91,
In sum, the fact that the statute upon which the visitation order was based has been declared unconstitutional is a substantial change in circumstances. Yet, in the context of child custody eases, we have also required the change to “relate to the welfare of the children.”
In re Marriage of Frederici,
Although res judicata is founded on important policy considerations, those considerations must give way at least when, as in this case, claim preclusion would result in the State’s continuing violation of аn individual’s fundamental constitutional rights. As previously noted, the Arkansas Supreme Court rejected this conclusion in
Hunt v. Perry,
holding that “a change in circumstances that prevents the application of
res judicata
is a change in the circumstances of the parties, not the law.”
Hunt,
If a statute that authorized a term or condition of visitation- is declared unconstitutional, that change should operate like any other change in circumstances that potentially makes the order unworkable or inappropriate. There is nothing in the statute that limits the change in circumstances to factual changes rather than changes in law.
In re T.J.K.,
B. Other Arguments
Wanda and Jim next argue that even if section 598.35(1), upon which the visitation order is based, would normally be unconstitutional, it is constitutional as applied in this case because Sherry stipulated to the visitation. Wanda and Jim argue Sherry’s stipulation to visitation was “tantamount to a consent decree.”
In re Marriage of Ask,
This argument does not alter our res judicata analysis. The judgment in
System Federation No. 91
was also a consent decree.
Sys. Fed’n No. 91,
“The result is all one whether the decree has been entered after litigation оr by consent. In either event, a court does not abdicate its power to revoke or modify its mandate, if satisfied that what it has been doing has been turned through changing circumstances into an instrument of wrong. We reject the argument for the interven[o]rs that a decree entered upon consent is to be treated as a contract and not as a judicial act.... But in truth what was then adjudged was not a contract as to [anyone]. The consent is to be read as directed toward events as they then were. It was not an abandonment of the right to exact revision in the future, if revision should become necessary in adaptation to events to be.”
Id.
at 650-51,
[U]nder our decisions the binding force of a stipulation as to alimony, child support and custody depends on the approval of the court. It is the decree and not the contract that becomes binding. The stipulation becomes merged in the decree. And the court may disregard the stipulation entirely.
Brin v. Brin,
We also observe that this approach is consistent with our general approach in
Lynch v. Uhlenhopp,
Moreover, we also reject Wanda and Jim’s constitutional-as-applied argument because we have already held section 598.35(1) is unconstitutional on its face.
In re Marriage of Howard,
Finally, Wanda and Jim argue that the district court never had jurisdiction to modify the visitation order because Sherry did not file her petition within the time required by rule 1.1013, our rule governing petitions to vacate or modify final judgments. This argument fails because Sherry’s failure to cоmply with our rule governing modifications of final judgments does not deprive the court of its common-law power to modify judgments granting continuing relief and regulating future conduct upon a substantial change in circumstances. See Restatement (Second) of Judgments § 73, at 197 (“[A] judgment may be set aside or modified if: ... [t]here has been such a substantial change in the circumstances that giving continued effect to the judgment is unjust.”).
C. Sherry’s Request for Appellate Attorney Fees
The final issue in this appeal is Sherry’s request for appellate attorney fees. An award of appellate attorney fees is within the discretion of the appellate court.
In re Marriage of Ask,
IV. Conclusion
Res judicata does not bar Sherry’s petition to modify or vacate the visitation order because the change in the law recognizing the unconstitutionality of section 598.35(1) is a substantial change in circumstances justifying modification of the order. “[Gjiving continued effect to the [visitation order] is unjust,” Restatement (Second) of Judgments § 73(2), at 197, because it constitutes a continuing violation of Sherry’s constitutional right as a mother to make decisions regarding her children’s well-being absent a showing of harm to them or her unfitness. The fact that the order was based on a stipulation of the parties does not alter this result. The district court was therefore correct in vacating the visitation order. We affirm the district court judgment and remand for determination of Sherry’s request for appellate attorney fees.
AFFIRMED AND REMANDED.
Notes
. Both parties reference the “law of the case” doctrine, but that doctrine is inapplicable. The law of the case doctrine says:
[A]n appellate decision becomes the law of the case and is controlling on both the trial court and on any further appeals in the same case. Springer v. Weeks & Leo Co.,475 N.W.2d 630 , 632 (Iowa 1991). Like res judicata, the law of the case doctrine is founded on a public policy against reopening matters which have been decided. Wolfe v. Graether,389 N.W.2d 643 , 651 (Iowa 1986) (citing 46 Am Jur.2d Judgments § 400, at 568 (1969)). Thus, issues decided by an appellate court generally cannot be reheard, reconsidered, or relitigated in the trial court. 5 C.J.S. Appeal and Error § 975, at 476-77 (1993). The appellate court decision is final as to all questions decided and the trial court is obligated to follow that decision. Id.
United Fire & Cas. Co. v. Iowa Dist. Ct.,
. In addition, Iowa Rule of Civil Procedure 1.1012 provides for modification of judgments under certain circumstances listed in the rule. See Iowa R. Civ. P. 1.1012 (grounds for modifying or vacating). However, petitions for relief under that rule must be filed within one year of the entry of the judgment or order involved. Id. r. 1.1013(1). Here, Sherry did not file her petition to modify until April 27, 2004 — two years and eight months after the visitation order was filed on August 21, 2001. Therefore, even assuming one of the grounds listed in rule 1.1012 applied to Sherry, she could not modify the judgment under that rule.
