Dana Donald was taken into protective custody on January 14, 1983 by the Polk County Department of Social Services. Following a probable cause hearing and jury trial finding that Dana had been physically abused, Dana remained in the Department’s custody until June 1, 1986, when she returned to her parents’ custody. Dana, her parents, Walter and Kathryn, and her siblings brought this action under 42 U.S.C. § 1983, claiming that the defendants — Polk County welfare and law enforcement officers and agencies — violated the Donalds’ constitutional rights by removing Dana from their home and improperly investigating Dana’s case. The district court held that the Donalds’ claims are barred by the doctrine of collateral estop-pel and granted summary judgment for the defendants. We affirm.
*378 I. BACKGROUND
The following facts are undisputed. In January 1983, Dana Donald was a ten-year-old epileptic child with a mental age of less than four years. Prior to 1983, agents or employees of defendant Polk County Department of Social Services (Department) had contacted Dana’s parents, plaintiffs Walter and Kathryn Donald, on several occasions concerning possible abuse of Dana. 1
On January 13, 1983, school officials contacted Nancy L. Stewart, a Department dispositional worker, and informed her that Dana had two sores on her back that the school officials suspected may have been caused by other than accidental means. Stewart then consulted her supervisor, defendant Calvin G. Schladweiler, and they jointly decided that Stewart would interview Dana on Friday, January 14, 1983.
During her January 14 interview with Dana, Stewart observed two circular lesions on Dana’s back, each smaller than a dime. Dana gave four or five different explanations for the injuries on her back. Stewart believed that the injuries may have been intentionally inflicted. Stewart returned to her office and discussed taking Dana into custody with Schladweiler and Dave Sarow, an intake worker. 2 It was decided at that meeting to take Dana into custody to avoid the possibility of further injury.
Stewart picked up Dana at her school and took Dana to a physician, who examined her. Stewart then took Dana to a foster home for the weekend until a probable cause hearing, could be held on Monday, January 17. Although the intake form indicated that Stewart notified Dana’s parents at 4:00 p.m. on January 14, she did not do so. When Dana did not arrive home on the school bus, the Donalds were greatly concerned and reported to the sheriff that she was missing. Only after prompting by the FBI, the sheriff told the Donalds that Dana was in the custody of the Department. When the Donalds tried to learn more, Stewart merely said that Dana was in protective custody and that she would see them in court on the following Monday.
Pursuant to Wisconsin law, Wis.Stat. Ann. § 48.255, Stewart filed a petition alleging that Dana was in need of protection and services. In this petition, Stewart stated that Dana had two circular lesions on her back and that a physician had stated that the injuries were burns. In addition, the petition stated that Dana had several circular scars on her hands and feet. Stewart also related the injuries to Dana that had been the subject of earlier contacts between the Department and the Donalds.
On Monday, January 17,1983, a probable cause hearing was held in the state court to determine whether the county should continue to hold Dana in custody. The court found probable cause to keep Dana in custody pending a fact-finding hearing to determine whether Dana was in need of protection.
A jury trial was held on February 11, 1983. The jury returned a verdict that Dana had been physically abused. Concluding that Dana was in need of protection, the state court ordered that she continue in the Department’s custody pending a dispositional hearing.
The dispositional hearing was held on March 8, 1983. The state court ordered that Dana be placed in foster care. Dana remained in foster care until June 1, 1986, when she returned to her parents’ custody.
II. STANDARD OF REVIEW
The district court granted the defendants’ motion for summary judgment. A district court should grant summary judgment only when there is no genuine issue as to any material fact and the moving party is entitled to judgment as a matter of law. Fed.R.Civ.P. 56(c). In reviewing a grant of summary judgment, we must first determine whether there are any
*379
genuine issues of material fact. “ ‘[T]o preclude summary judgment, the nonmov-ing party must show the disputed fact to be material, that is, it must be outcome-determinative under the applicable law.... [F]acts not outcome-determinative under the applicable law, though in dispute may still permit the entry of summary judgment.’ ”
Wallace v. Greer,
To prevail on a claim under section 1983, the Donalds must show that: (1) they held a constitutionally protected right; (2) they were deprived of this right in violation of the Constitution; (3) the defendants intentionally caused this deprivation; and (4) the defendants acted under color of law.
3
Summary judgment is proper against a party who fails to establish the existence of an element essential to his case, and on which that party will bear the burden of proof at trial. As the Supreme Court recently stated: “In such a situation, there can be ‘no genuine issue as to any material fact,’ since a complete failure of proof concerning an essential element of the nonmoving party’s case necessarily renders all other facts immaterial.”

U.S. 317,
III. ANALYSIS
The Donalds claim that the defendants violated several of their constitutional rights. The Donalds assert that because the defendants took Dana into custody without first providing notice and a hearing, the defendants violated their right to procedural due process under the fourteenth amendment. The Donalds also argue that the defendants deprived them of substantive constitutional rights without due process of law, including the right to family privacy and family life; the right to be offered social services under Chapter 48 of the Wisconsin Statutes; and the right to be free from unreasonable searches and seizures. Finally, the Donalds claim that the defendants violated their right to equal protection under the laws of Wisconsin, contrary to the equal protection clause of the fourteenth amendment. We will consider each of these contentions in turn.
A. Procedural Due Process
The Donalds’ most cogent argument is that the Department took Dana into custody without prior notice to her parents 4 or any opportunity for a pre-taking hearing. *380 Drawing all reasonable inferences in the light most favorable to the Donalds, it is nevertheless clear that this claim cannot survive because the Donalds failed to show actual damages resulting from the postde-privation notice and hearing, an essential element of their claim.
In its opinion, the district court primarily relied on
Lossman v. Pekarske,
The fourteenth amendment forbids a state from taking one’s life, liberty or property without due process of law. For purposes of ruling on the grant of summary judgment, we will assume that the Donalds were deprived of liberty when the defendants took Dana into custody. 5
We next must consider whether the Don-alds were afforded due process of law. In
Lossman,
this court held that the postde-privation hearing that Lossman received satisfied due process.
Lossman
also emphasized that suits under section 1983 are tort damage actions. As in any tort action, a plaintiff under section 1983 cannot survive summary judgment unless he has sustained actual damages.
Lossman,
Likewise, the Donalds have suffered no actual damages. In the adversarial hearing before the Wisconsin state court on Monday, January 17, 1983, the judge found probable cause that Dana’s injuries were intentionally caused and that she was in danger of further injury if allowed to return home. The Donalds do not contend that the hearing itself was inadequate for due process purposes. If probable cause to take Dana into custody existed on Monday, January 17, the defendants also must have had probable cause to take Dana into custody on the previous Friday. All of the evidence of abuse before the court on January 17 was based on events that occurred on January 14 or before. Lossman teaches that if an earlier notice or hearing would not have prevented the removal of the child from her home, and the delay was justified, the delay in the notice or hearing could not injure the plaintiff.
The only possible injury the Donalds have claimed is the anxiety they suffered as a result of the delay in notifying them of Dana’s whereabouts on January 14. The probable cause hearing on January 17 and the subsequent jury trial both established that Dana was an abused child and therefore a true emergency existed on January 14 when the defendants took her into custody. In an emergency situation, the government may take away property or liberty, so long as postdeprivation notice and a hearing are provided.
See, e.g., Hodel v. Virginia Surface Mining & Reclamation Ass’n, Inc.,
Maybe they could have reached Lossman earlier in the day to tell him what they were doing, but their failure to do so was not significant. It would have been irresponsible for them to have left the children in Lossman’s custody.... And if there was, therefore, no denial of due process in depriving Lossman of his custody of the children, and therefore no improper deprivation of a constitutionally protected liberty, any anxiety the defendants may have created in Lossman’s mind regarding the whereabouts of the children would not support a constitutional claim. Peace of mind is not liberty.
Lossman,
B. Right to Family Life
The Donalds’ next major contention is that the defendants violated the Donalds' constitutional right to family privacy and family life by conspiring to “perpetrate a fraud upon the court,” resulting in Dana’s removal from the Donald household. The Donalds claim that the defendants accomplished this by using their investigation, reports, petitions to the court, and sworn testimony to create the false impression that Dana was being abused. The Don-alds, however, completely fail to support these broad, vague allegations. The Don-alds have cited absolutely no specific instances of a false statement or even an exaggerated statement in any of the defendants’ reports, petitions, or testimony. While the Donalds claim the defendants’ investigation was biased, they propose no reasonable motive why the defendants would be prejudiced against the Donalds. Thus, the Donalds’ claim of a conspiracy to perpetrate a fraud upon the court is not a genuine issue of fact because it could not “reasonably be resolved in favor of either party.”
Anderson v. Liberty Lobby, Inc.,
The district court found that the doctrine of collateral estoppel barred the Donalds’ claims. The doctrine of collateral estoppel, also called issue preclusion, generally prevents a party from relitigating an issue the party has previously litigated and lost. This policy promotes judicial efficiency and prevents inconsistent decisions while affording each party one fair opportunity to litigate an issue.
Allen v. McCurry,
A federal court must give the same preclusive effect to a state court ruling as would a court in the rendering state.
Migra v. Warren City School Dist. Bd. of Educ.,
The defendants argue that collateral estoppel precludes the Donalds from claiming that the defendants were not truthful in their reports, investigations, court petitions, and court testimony. At the outset, we note that the Donalds could have raised their claims of fraud and bad faith in the state court, and clearly the risk of losing custody of Dana provided them with a strong incentive to do so. Nevertheless, they did not specifically raise the issue of fraud in the state court proceedings, although the Donalds had a full and fair opportunity to do so. The Donalds claim that they were not aware of the alleged fraud at the time of the state court proceedings. We fail to see how the Donalds could not have been aware of the alleged falsities; the Donalds do not claim that they were not afforded full discovery rights or were not allowed to listen to the in-court testimony of the defendants.
We agree with the district court that the Donalds’ claims are precluded by the doctrine of collateral estoppel. The Donalds claim that the defendants’ testimony, petitions, and reports were false. The jury necessarily decided this issue in reaching its verdict. If the jury had not believed the defendants, the defendants could not have met their burden of clear and convincing evidence.
See Chrysler Corp. v. Lakeshore Commercial Fin. Corp.,
The Donalds claim, however, that collateral estoppel should not apply in this case because they did not receive a full and fair opportunity to litigate the issue of whether the defendants were fraudulent. Wisconsin courts permit parties to avoid the appli
*383
cation of collateral estoppel if they did not have a full and fair opportunity to pursue their claim in the initial action.
Crowall,
Applying Wisconsin law as articulated in Spearing, we believe that a Wisconsin court would find that the earlier state court trial foreclosed the Donalds’ claims of fraud. As in Spearing, the Donalds could have pursued their claims of fraud through the state appellate process. The court in Spearing also relied on the fact that the plaintiffs’ claims were unfounded. As we noted, the Donalds have failed to support their conclusory allegations of bad faith on the part of the defendants. The Donalds had every incentive and opportunity to raise all possible arguments at both the probable cause hearing and the later jury trial. Because Wisconsin courts, applying the approach in Spearing, would find these claims foreclosed, the Donalds are also pre-eluded from bringing these claims in federal court.
C. Right to Social Services
The Donalds’ third claim is that the defendants deprived them of their right to social services under Chapter 48 of the Wisconsin Statutes. Wisconsin law mandates that appropriate services are to be provided to the family of any child that the county welfare agency determines to be in need of services. If the family refuses such services, the statute provides that a petition that the child is in need of protection or services may be filed. Wis.Stat. Ann. § 48.981(3)(c)(3) (1987). The district court found that while the statute provides one method in which county welfare workers may proceed in deciding whether to file a petition, the statute does not limit emergency procedures for taking a child into custody.
In any event, this court has held that a statutory obligation to provide social services is not a constitutionally protected right. In
DeShaney v. Winnebago County Dep’t of Social Servs.,
The men who framed the original Constitution and the Fourteenth Amendment were worried about government’s oppressing the citizenry rather than about its failing to provide adequate social services. For such failures, political remedies (along with such legal remedies as states might see fit to provide in their own courts) were assumed to be adequate.
Id.
at 301. Because the right to receive social services is not a constitutionally protected right, the Donalds failed to establish
*384
an essential element of their section 1983 claim. The district court therefore properly awarded the defendants summary judgment on this issue.
Celotex Corp. v. Catrett,
D. Right to be Free from Unreasonable Seizures
The Donalds next claim that the defendants violated their fourth amendment right to be free from unlawful searches and seizures. None of the plaintiffs in this case have been the object of a search or seizure, with the possible exception of Dana. In
Lossman v. Pekarske,
this court questioned whether a child is truly deprived of a liberty interest when custody is transferred from the parents to the state.
The fourth amendment, as applied to the states by the fourteenth amendment, only prohibits “unreasonable” seizures. A seizure is lawful if a judicial officer finds probable cause to hold the seized individual either before or promptly after the individual is taken into custody.
Baker v. McCollan,
Intake and dispositional workers have the power of police officers for the purpose of taking children into physical custody where the child is in immediate danger from her surroundings. Wis.Stat.Ann. § 48.08(2) (1987). Pursuant to Wisconsin law, the Department took Dana into custody on January 14 only after an intake worker found probable cause to believe that if Dana was not taken into custody, she would be subject to injury by others. Id. § 48.205(l)(a). A hearing to determine whether the Department should continue to hold Dana was held on January 17, as Wisconsin law mandates. Id. § 48.21(1) (hearing must be held within twenty-four hours, excluding Saturdays and Sundays, of the time the decision to hold the child was made).
If Dana was seized, it was not an illegal act. The defendants acted according to the statutory requirements of Wisconsin law. Defendant Stewart made a finding of probable cause that Dana was at risk of immediate injury if not taken into custody, just as a police officer in the field can make an arrest based on her own determination of probable cause.
United States v. Watson,
Applying these principles, collateral es-toppel bars the Donalds’ claims based on the fourth amendment. On January 17, the state court found probable cause to continue to hold Dana in custody. Because Dana was in custody from the time of the initial probable cause determination by the Department workers until the hearing on January 17, the state court could only have
*385
based its finding of probable cause on events that occurred prior to taking Dana into custody. Therefore, the state court’s determination that probable cause to hold Dana existed on January 17 necessarily implied that probable cause must also have existed on January 14. The Donalds cannot relitigate the issue of probable cause in federal court after it has been conclusively determined in state court.
See Lossman,
E. Equal Protection
Finally, the Donalds complain that the defendants violated their fourteenth amendment right to equal protection under the laws of Wisconsin. The gist of this claim is that the defendants conducted their investigation because of the Donalds’ poverty and relative lack of education. The Donalds claim that, because defendants were aware of the Donalds’ economic and educational background, “[a] jury could easily find at trial that defendants were motivated by plaintiffs’ poverty, source of income, and lack of education.” Even assuming a jury would make the jump from mere knowledge to motivation, the Lossman decision forecloses this avenue of recovery.
As the district court found, the Donalds have advanced no evidence that the defendants proceeded as they did because of the Donalds’ education or financial status.
IV. CONCLUSION
Despite their many claims of constitutional violations, the Donalds’ underlying complaint seems to be that they are unhappy with the jury verdict resulting from the state trial. If so, their proper avenue of redress would have been to appeal that verdict. Instead, the Donalds chose to bring this section 1983 action. “In passing § 1983, ‘[Congress did not intend] to allow relitigation after a full and fair hearing simply because the state court’s decision may have been erroneous.’ ”

Stanley v. Illinois,
. The record does not state the exact time that the Donalds were notified of Dana’s whereabouts, nor does it indicate what time Dana would normally arrive home on the school bus.
. Although collateral estoppel does apply to issues actually litigated in a previous action, the Court in
Allen
qualified their holding by noting that "this case does not involve the question whether a § 1983 claimant can litigate in federal court an issue he might have raised but did not raise in previous litigation."
. The traditional rule of mutuality allowed courts to apply collateral estoppel only to actions between the same parties, or their privies, that were involved in the previous proceeding.
. The Donalds insist that while the emergency procedures outlined in the statute are not exclusive, the Department decided to use emergency procedures in bad faith, knowing that no true emergency existed. The state court finding of probable cause on January 17, however, precludes the Donalds from claiming that a true emergency did not exist on January 14.
