TELLEEN, Senior Judge.
In 2004, Dr. Moulay Tidriri was denied promotion to full professor at Iowa
State University. Dr. Tidriri has spent the following two decades seeking to reverse
that 2004 denial of promotion. In that time, he has brought various claims against
the university and the other defendants in this case (collectively, “ISU”) in an effort
to obtain his long-sought promotion, all of which have categorically failed. We echo
the sentiments expressed by the federal district court in one of Dr. Tidriri’s prior
suits, “This [c]ourt has wasted precious time and judicial resources on [Dr. Tidriri]’s
cases.” See Tidriri v. Bd. of Regents, No. 4:20-CV-00085, 2020 WL 6342750, at *1
(S.D. Iowa Sept. 24, 2020), aff’d, 859 F. App’x 745 (8th Cir. 2021) [hereinafter
Tidriri I].
Dr. Tidriri first appealed the promotion denial decision to the university’s
appeals committee and provost, as well as the Iowa Board of Regents. He then
lodged corruption and obstruction complaints with the chair of the university
mathematics department in 2005, 2006, and 2007, initiating each successive
complaint after the previous one was investigated and closed. Dr. Tidriri then
alleged that ISU retaliated to his complaints through further corruption and
fabrication of evidence. So in 2008 and 2009 he filed complaints with the U.S.
Equal Employment Opportunity Commission and Iowa Civil Rights Commission,
alleging multiple claims against ISU, including wrongful conduct, abuse of funds,
harassment, and hostile work environment. Those complaints were
administratively closed.
After the failure of these complaints and their associated appeals, Dr. Tidriri
then sued ISU in the Story County district court in 2011. He alleged that ISU 4
committed breach of contract, violated the Iowa whistleblower statute, intentionally
inflicted emotional distress, retaliated against him, denied him due process and
equal protection, and caused him damages due to their acts in relation to his denial
of promotion. This suit proceeded to trial in 2014, and a jury verdict denied all of
Dr. Tidriri’s claims.
Following a 2013 complaint, the university’s faculty review board
determined in January 2014 that Dr. Tidriri had engaged in unacceptable
performance of his teaching, research, and service duties over the previous five
academic years. Dr. Tidriri opted to have the resulting sanction decided by an
administrative law judge rather than by the university’s major sanction committee.
The administrative law judge concluded that Dr. Tidriri refused to cooperate with
the expectations and processes “by which all faculty are governed,” such as
refusing to produce a curriculum vitae (CV),1 failing to complete annual reports and
forms,2 refusing required classroom observation for post-tenure reviews,3 and
refusing to propose any alternative plan of action or engage in mediation. The
administrative law judge noted that Dr. Tidriri’s complaints that the university failed
to accommodate him following his refusals to cooperate with required procedures
and policies was “reminiscent of a demand for sympathy as an orphan after killing
1 The administrative law judge found that Dr. Tidriri had produced a CV of less than
one page when comparable associate professors typically produce CVs ranging from eleven to over fifty pages in length. For example, his complete list of publications was summarized as, “Some publications.” At least one of the journals with which Dr. Tidriri testified to have a pending publication stated it had never seen a draft or abstract of such publication. 2 These failures resulted in the loss of research grant funding for the university. 3 This refusal was notable considering student reviews that reported Dr. Tidriri as
“late to class, rude, disrespectful, condescending, insulting, nonresponsive to questions, . . . and a poor teacher of the subject matter.” 5
one’s parents.” Dr. Tidriri was recommended for immediate termination, which the
university president approved and fully adopted. Dr. Tidriri then appealed the
termination decision to the Iowa Board of Regents which affirmed the decision in
February 2015.
Dr. Tidriri then began a spate of federal lawsuits against ISU. See Tidriri v.
Vermeer Andringa, No. 4:17-cv-00066 (S.D. Iowa Feb. 22, 2017); Tidriri v. Bd. of
Regents, No. 4:19-cv-00321, 2020 WL 6281405 (S.D. Iowa Sept. 24, 2020);
Tidriri I, 2020 WL 6342750; Tidriri v. Iowa State Univ., 4:23-cv-00373, 2024
WL 3394783 (S.D. Iowa June 3, 2024) [hereinafter Tidriri II]. All those cases were
dismissed. In his most recent federal suit, the federal district court observed that
Dr. Tidriri “is a vexatious litigant based on his harassing litigation behavior and
abuse of the judicial process.” See Tidriri II, 2024 WL 3394783, at *1. Despite
previous courts’ warnings that his cases are baseless and “frivolous,” Dr. Tidriri
“has responded by filing . . . more frivolous lawsuits which again waste judicial (and
government attorney) resources and time in a quixotic attempt to reverse
employment decisions by Iowa State University.” Id. Most recently, the federal
district court ordered that Dr. Tidriri “is ENJOINED from filing any new legal actions
in the United States District Court for the Southern District of Iowa” against ISU or
“concerning facts or issues involved in this or the related cases identified above”
unless represented by counsel or having obtained written authorization from a
district judicial officer. Id. at *7.
Dr. Tidriri also filed this suit in October 2023, around the same time as his
latest federal suit. In his fifty-three-page petition he alleged that ISU committed
numerous constitutional violations, negligence, breach of contract, and wrongful 6
discharge. The district court granted ISU’s pre-answer motion to dismiss
Dr. Tidriri’s petition.4

latest federal suit. In his fifty-three-page petition he alleged that ISU committed
numerous constitutional violations, negligence, breach of contract, and wrongful 6
discharge. The district court granted ISU’s pre-answer motion to dismiss
Dr. Tidriri’s petition.4
We recap this procedural history to emphasize that the claims Dr. Tidriri
now brings have been litigated thoroughly and repeatedly throughout his years of
previous suits and appeals against ISU. While we agree and find no error in the
district court’s well-reasoned analysis on all points, this case can be most
persuasively disposed of based on the principle of res judicata: each claim now
raised was previously raised and fully litigated against the same defendants in
Dr. Tidriri’s 2014 jury trial. See Hedlund v. State, 875 N.W.2d 720, 724–27
(Iowa 2016).
Under the doctrine of res judicata, a court’s final judgment “constitutes an
absolute bar to a subsequent action involving the same claim, demand or cause
of action.” Bennett v. MC # 619, Inc., 586 N.W.2d 512, 516 (Iowa 1998) (citation
omitted). Res judicata encompasses both claim preclusion—barring further
litigation on a claim—and issue preclusion—barring further litigation on a specific
issue. Id. A previous final judgment “between the same parties on the same claim
is final as to all issues that could have” potentially been brought before the court
on that claim. Id. at 517. We apply this doctrine to prevent a plaintiff from “a
‘second bite’ simply by alleging a new theory of recovery for the same wrong.” Id.
(citation omitted).
4 Dr. Tidriri argues in part, for the first time on appeal, that the federal district court
violated Iowa law by dismissing his federal suit’s claims under the Iowa Civil Rights Act and Whistleblower Act. We do not have jurisdiction to hear appeals from federal district court orders. See 28 U.S.C. § 1291 (giving federal appellate courts “jurisdiction of appeals from all final decisions of the district courts of the United States”). 7
As the district court stated, “[Dr. Tidriri]’s Petition demonstrates that he is
attempting to attack the evidence admitted in that [2014] case and therefore the
results of that trial. . . . [T]he case at hand is a transparent attempt by [Dr. Tidriri]
to relitigate matters which have already been decided by the courts.” We agree.
And Dr. Tidriri cannot circumvent res judicata by marginally and superficially
tweaking the same claims he previously made against the same defendants, most
notably in his assertions the ISU fabricated evidence and continued its damaging
acts during the 2014 trial and administrative hearing.
Finding all of Dr. Tidriri’s claims thoroughly precluded by res judicata, we
thus affirm the district court’s order dismissing his petition.
AFFIRMED.
