Eric Plough brought this 42 U.S.C. Sec. 1983 action against the West Des Moines School District (the School District) claiming it violated his due process rights during disciplinary hearings against him. The district court1 granted summary judgment in favor of the School District finding that Plough was barred by the doctrine of res judicata from relitigating his claim in federal district court. Plough appeals. Because Plough has already had a full and fair opportunity to litigate these matters in the state forum, we affirm.I. BACKGROUND

After admitting he had been in possession of lysergic acid diethylamide (LSD) on school grounds in violation of the school's substance abuse policy, Plough was given a hearing by the School District's Board of Directors (School Board). Following the adversarial hearing at which Plough was present and represented by counsel, the School Board retired for private consideration of the case. During this discussion, two School Board members spoke out against Plough, claiming personal knowledge about his case.2 The School Board subsequently voted to suspend and expel Plough from school.3 Because Plough was unaware of the improper statements until after the School Board's decision, he had no chance to question the School Board members or refute their allegations.

Plough appealed to the Iowa State Board of Education (State Board) claiming the School Board violated his due process rights by considering what amounted to testimony by the School Board members. On appeal, the State Board held an evidentiary hearing4 and affirmed the School Board's disposition of the case. Plough did not appeal this decision to the Iowa district court, as was his right under Iowa law.

Plough then filed this section 1983 action in federal district court against the School District and its Board of Directors. He sought damages and expungement of any reference to suspension or expulsion from his school record. The district court granted the School District's motion for summary judgment on res judicata grounds. Plough appealed.

On appeal, Plough argues that summary judgment was inappropriate because it incorrectly gave preclusive effect to the State Board's decision on his due process claim. Summary judgment is proper only when no genuine issue of material fact is present and judgment should be awarded to the movant as a matter of law. Percival v. General Motors Corp., 539 F.2d 1126, 1128 (8th Cir.1976). Because of the extreme nature of summary judgment, it "should not be granted unless the moving party has established the right to a judgment with such clarity as to leave no room for controversy." Jewson v. Mayo Clinic, 691 F.2d 405, 408 (8th Cir.1982). We review the entry of summary judgment de novo, giving the nonmoving party the benefit of every inference drawn from the evidence. Buford v. Tremayne, 747 F.2d 445, 447 (8th Cir.1984) (citing Bryan v. Aetna Casualty & Surety Co., 381 F.2d 872, 875 (8th Cir.1967)).

The district court granted summary judgment for the defendants, finding that the doctrine of res judicata barred Plough's section 1983 action.5 As used by the district court, the term "res judicata," includes both issue and claim preclusion. See, e.g., Migra v. Warren City School Dist., 465 U.S. 75, 77 n. 1, 104 S. Ct. 892, 894 n. 1, 79 L. Ed. 2d 56 (1984). Issue preclusion, or collateral estoppel, provides that "once a court has decided an issue of fact or law necessary to its judgment, that decision may preclude relitigation of the issue in a suit on a different cause of action involving a party to the first case." Allen v. McCurry, 449 U.S. 90, 94, 101 S. Ct. 411, 414, 66 L. Ed. 2d 308 (1980) (citing Montana v. United States, 440 U.S. 147, 153, 99 S. Ct. 970, 973, 59 L. Ed. 2d 210 (1979)). See also Hunter v. City of Des Moines, 300 N.W.2d 121, 123 (Iowa 1981). Claim preclusion, or res judicata, provides that "a final judgment on the merits of an action precludes the parties or their privies from relitigating issues that were or could have been raised in that action." Allen v. McCurry, 449 U.S. at 94, 101 S.Ct. at 414 (citing Cromwell v. County of Sac, 94 U.S. 351, 352, 24 L. Ed. 195 (1876)).

Because we are dealing with the factfindings of an agency, the Iowa State Board of Education, we must first determine whether such factfindings are to be given preclusive effect. The applicable standard is:

[W]hen a state agency "acting in a judicial capacity ... resolves disputed issues of fact properly before it which the parties have had an adequate opportunity to litigate," federal courts must give the agency's factfinding the same preclusive effect to which it would be entitled in the State's courts.

University of Tennessee v. Elliott, 478 U.S. 788, 799, 106 S. Ct. 3220, 3226, 92 L. Ed. 2d 635 (1986) (quoting United States v. Utah Constr. & Mining Co., 384 U.S. 394, 422, 86 S. Ct. 1545, 1560, 16 L. Ed. 2d 642 (1966)).6 Thus, before examining the extent to which Iowa law would give the State Board's factual findings preclusive effect, the three Elliott "eligibility" factors must be considered. We find that all three prerequisites were met in the present case. First, the State Board was acting in a judicial capacity when it reviewed the School Board's decision.7 Second, the State Board resolved issues of fact (the circumstances surrounding Plough's suspension and expulsion) properly before it. Third, Plough had an adequate opportunity to litigate the facts underlying his due process claim during the State Board's de novo review of the School Board's proceedings.8

To comply with Elliott 's mandate that an agency's factfindings be given the "same" preclusive effect as under state law, we must next determine the preclusive effect an Iowa court would give the factfindings. See Migra, 465 U.S. at 81, 104 S.Ct. at 896. Under Iowa law, issues of fact are given preclusive effect if: (1) the issue of fact concluded is identical to that concluded in the prior action;9 (2) the issue of fact was raised and litigated in the prior action; (3) the issue of fact was material and relevant to the disposition of the prior action; and (4) the determination made of the issue of fact in the prior action was necessary and essential to the resulting judgment. Yancy v. McDevitt, 802 F.2d 1025, 1027-28 (8th Cir.1986) (citing Hunter, 300 N.W.2d at 123).

The facts offered by Plough in support of his due process claim in federal district court were the same facts submitted to the State Board. The State Board considered and rejected Plough's factual allegations. The most important finding by the State Board was that Plough was not prejudiced by the addition of the improper testimony at his School Board hearing. A finding of prejudice, or a lack thereof, is a finding of fact. See U.S. v. Pratt, 31 F.3d 625, 627 (8th Cir.1994), cert. denied, --- U.S. ----, 115 S. Ct. 774, 130 L. Ed. 2d 669 (1995); In re South Carolina Press Ass'n, 946 F.2d 1037, 1040 (4th Cir.1991). That finding negates Plough's due process claim.

Plough argues the factual issues were not identical in the two proceedings because his requests for relief were not the same.10 In addition to expungement of his school record, Plough requested damages, which were unavailable at the State Board level, in his section 1983 action. Plough's argument fails, however, as requested remedies need not remain the same in order for issue preclusive effect to be given a prior determination. See, e.g., Utah Constr., 384 U.S. at 418, 86 S.Ct. at 1558 (holding an agency's factual findings were preclusive in a later suit even though the request for and ability to allow damages were not the same in the two proceedings); Buckingham v. Federal Land Bank Ass'n, 398 N.W.2d 873, 875 (Iowa 1987) (holding the addition of a request for punitive damages in second action did not prevent preclusion in that action as identity of issue was not altered).

The remaining three prerequisites for the application of issue preclusion under Iowa law are also satisfied in the present case. At the State Board level, an evidentiary hearing was conducted at which Plough raised and litigated his due process claim. The State Board's rejection of Plough's factual allegations, including his claim that he suffered prejudice, was clearly material to its disposition of the case as it was the basis for the State Board's affirmance of the School Board's action. Finally, both Plough's guilt and the finding of no prejudice were necessary findings in the State Board's affirmance of the School Board's expulsion. Had the State Board found Plough suffered prejudice, it would have reversed the School Board's decision. For the above reasons, therefore, Plough is barred by the doctrine of issue preclusion from relitigating these facts in federal court.

Although issue preclusion adequately disposes of Plough's case, claim preclusion does so as well. Claim preclusion, or res judicata, "bars relitigation of the same claim between parties or their privies where a final judgment has been rendered upon the merits by a court of competent jurisdiction."11 Smith v. Updegraff, 744 F.2d 1354, 1362 (8th Cir.1984). The party against whom res judicata is to be used, however, must have had a full and fair opportunity to investigate and litigate the matter concluded. Id. Plough was afforded exactly that--a full and fair opportunity to litigate his due process claim in front of the State Board.

The federal district court was bound to give the State Board's decision the same preclusive effect as the state courts would. See Migra, 465 U.S. at 81, 104 S.Ct. at 896. Under Iowa law, an unreviewed administrative decision can be given preclusive effect in a later proceeding. See Yancy, 802 F.2d at 1028 (emphasizing the existence of numerous procedural safeguards which make school board decisions subject to preclusive effect in later proceedings). See also Knudsen v. Chicago & North Western Transp., 464 N.W.2d 439, 444 (Iowa 1990). This is especially true regarding the preclusive effect of claims, such as Plough's, based on 42 U.S.C. Sec. 1983 and involving the same subject matter as the prior proceeding. Abramson v. Council Bluffs Community Sch. Dist., 808 F.2d 1307, 1309 (8th Cir.1987).

In this case, Plough attempts to litigate the same due process claim against the same defendants. This he may not do. The State Board specifically addressed Plough's due process claim and decided it adversely to him. That decision became final when Plough chose not to appeal it. He chose to litigate this claim in a state forum and is now barred from relitigating the same claim in federal court. See, e.g., Clarke v. Redeker, 406 F.2d 883, 885 (8th Cir.1969) (precluding section 1983 action for damages because earlier action seeking injunctive relief on essentially same facts had already been adjudicated), cert. denied, 396 U.S. 862, 90 S. Ct. 135, 24 L. Ed. 2d 115 (1969).

We think it unfortunate that the School Board members injected improper testimony into Plough's expulsion proceeding, because it was not relevant. When dealing with matters as important as a student's right to be in school, such information should not be included as part of the discussion. However, in this case, any alleged error by the School Board was harmless as the State Board expressly found that Plough was not prejudiced by the additional testimony. Although we do not condone the School Board's actions, any error which occurred there was cured by the State Board's de novo review of the case. We have considered the remainder of Plough's arguments and find them to be without merit.

In sum, Plough is barred from relitigating his due process claim in federal district court. He has already had a full and fair opportunity to litigate these matters before the Iowa State Board of Education. The order of the district court granting summary judgment in favor of the West Des Moines Community School District and its Board of Directors is affirmed.
