No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 2
_________________
OPINION
_________________
COLE, Circuit Judge. Matthew Warman, a former graduate student at Mount St. Joseph
University (MSJU), objected to taking the COVID-19 vaccine on religious grounds. When
MSJU announced that it would require all students and employees to be vaccinated, Warman
applied for a religious exemption. Soon after, two officers with the MSJU Police Department
(MSJPD) allegedly detained him at the campus police station for an hour, attempting to convince
him to get the vaccine and disparaging his religious beliefs. Warman later sued MSJU, MSJPD,
and multiple individual employees. The district court dismissed his complaint. We affirm the
district court in part and reverse in part. We affirm the district court’s dismissal of Warman’s
free exercise, equal protection, and disability discrimination claims with prejudice, and we affirm
the dismissal of MSJPD from all counts with prejudice. But because Warman plausibly pleaded
that the two officers who detained him violated his Fourth Amendment rights, we reverse the
district court’s dismissal of Warman’s wrongful detention claim and reinstate the claim against
those defendants. And we vacate the district court’s declination of supplemental jurisdiction
over Warman’s state-law claims and remand for reconsideration.
I.
Because this case comes to us on an appeal of a motion to dismiss, “we recite the facts as
they are alleged in the complaint.” Savel v. MetroHealth Sys., 96 F.4th 932, 937 (6th Cir. 2024).
MSJU is a Catholic university in Cincinnati, Ohio. Around December 2020, Matthew
Warman enrolled in MSJU’s graduate nursing program. A former Marine, Warman was
medically discharged from the military due to internal injuries and brain tumors and suffered
from “post-discharge depression and anxiety[.]” (Second Am. Compl., R. 18, PageID 315.) The
Veterans Administration paid for Warman’s schooling at MSJU, though this support was
potentially subject to repayment if he failed to complete his studies.
MSJU began developing a COVID-19 vaccination policy and, upon commencement of
the Fall 2021 term, informed students that it was going to require vaccination. On September 9,

-- 2 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 3
2021, Warman proactively sought a religious exemption. He also submitted a medical
exemption letter from his doctor stating that Warman had a “medical need to avoid taking the
COVID vaccines.” (Id. at PageID 320.) A few days later, MSJU formally released its vaccine
policy, which required all current students and employees to be fully vaccinated and to submit
proof of vaccination by December 15, 2021, unless they obtained an exemption from the
university.
On September 15, 2021, MSJPD’s Chief of Police, Kevin Koo, called Warman to
campus “to speak with him about [Warman’s] decision to refuse the vaccine.” (Id. at PageID
321.) After receiving six phone calls and an email, Warman arrived at the campus police station
around 1:00 p.m. Koo and MSJPD Captain Norb Koopman “took [Warman] into a back room
. . . and would not allow him to leave[.]” (Id.) The officers held Warman there for
approximately one hour, telling him that he was required to stay until Karen Elliott, MSJU’s
Director of Mission and Ministry, arrived.
During that hour, Koopman and Koo berated Warman. They called Warman a “f*****g
idiot” and told him that he should “get a new religion[,]” that his “beliefs were wrong[,]” and
that he should “grow the f*** up and get the damn shot.” (Id. at PageID 321.) They also handed
him Veterans Administration paperwork and “told him to fill it out in order to resign from the
[u]niversity[,]” said that they “would take him to the student center to get vaccinated[,]” and
made other disparaging statements. (Id. at PageID 321–22.) Once Koopman and Koo learned
that Elliott was unable to come to the police station, they allowed Warman to leave.
On September 17, 2021, MSJPD posted a memorandum from Koopman and Koo
addressed to all officers that contained a picture of Warman, provided his class schedule,
described his car, and listed both his license plate and student permit numbers. The
memorandum included the following instruction:
Below is the photograph of Matthew Warman. If you see him on Campus, stop
him and check to see how he is doing. Politely ask why he is here. You are not to
arrest him or tell him to leave Campus. Just keep an eye on him. (Keep in mind
that he is a student here and has the right to be on Campus).

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 4
(Id. at PageID 323; Ex. A. of Compl., R. 1-1, PageID 30.) After the memorandum was posted,
Warman described being watched and followed by campus police officers, including one
incident where Koopman watched Warman take a call with his doctor.
On September 20, 2021, MSJU’s Health Services Manager, Amy Metzger, denied
Warman’s requested religious exemption to MSJU’s vaccination policy and referred Warman to
MSJU’s General Counsel, Paige Ellerman. The next day, Elliott called Warman to meet at her
office. Koopman “stationed himself outside the door” of Elliott’s office. (Second Am. Compl.,
R. 18, PageID 324.) During the meeting, Warman complained that he was being harassed by
MSJPD officers, though Elliott did not follow up on Warman’s concerns. Instead, Elliott
explained to Warman the necessities of getting vaccinated and that vaccination did not violate
Catholic edicts.
Undeterred by his meeting with Elliott, Warman appealed the denial of his religious
exemption on September 22, 2021, reiterating that his “sincerely held religious beliefs precluded
him, in his conscience, from accepting the vaccine.” (Id. at PageID 325.) Warman also
attempted to obtain a religious exemption from a hospital where he was set to perform clinical
work but was informed by the Assistant Dean of MSJU’s Department of Nursing, Nancy
Hinzman, that he could only obtain an exemption through MSJU. On October 4, 2021, Metzger
denied Warman’s appeal for a religious exemption.
Believing that he was still being harassed by MSJPD officers, Warman filed a complaint
on the campus police website but received no response. After Warman filed this complaint,
MSJPD retaliated by reporting Warman to the FBI and having FBI Agent Ron Willison contact
Warman’s psychiatrist. That call, according to Warman, sought “to cause [] Warman’s
psychiatrist to falsely believe that [] Warman presented a physical danger to students and staff on
campus, a risk of danger to himself, and a risk for causing campus violence[.]” (Id. at PageID
328.)
As a result of this “harassment” and “intimidation[,]” Warman withdrew from MSJU and
was obligated to return stipend funds he had received from the Veterans Administration for

-- 4 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 5
attending graduate school. (Id. at PageID 330.) He also alleges that the events caused him both
physical and emotional trauma.
Warman sued MSJU, MSJPD, and the individual employees he believed were
responsible for his harassment on campus and the implementation of MSJU’s vaccination policy.
He filed an amended complaint, which defendants moved to dismiss for failure to state a claim.
The district court denied defendants’ motion and granted Warman leave to further amend the
complaint to add new evidence.
In his second amended complaint, Warman sued MSJU and its Director of Mission and
Ministry Karen Elliott, Health Services Manager Amy Metzger a/k/a Amy Demko, General
Counsel Paige Ellerman, and the Assistant Dean in MSJU’s Department of Nursing Nancy
Hinzman. He also sued MSJPD and MSJPD officers Kevin Koo and Norb Koopman. He further
sued “John Does” and “ABC Agenc[ies]” which acted like the named parties toward Warman
and/or were responsible for creating and administering MSJU’s vaccine policy. Additionally, he
brought claims against the FBI and FBI Agent Ron Willison, though he later voluntarily
dismissed his claims against both.
Warman brought several federal and state claims against these defendants. Under
42 U.S.C. § 1983, he alleged that various defendants conspired to violate or violated his rights to
free exercise of religion, to equal protection, and against unlawful detention.1 He also alleged
that various defendants discriminated against him based on his actual or perceived disabilities
under the Rehabilitation Act, 29 U.S.C. § 793. His state law claims include intentional infliction
of emotional distress, invasion of privacy, false light, unlawful detention, false imprisonment,
tortious interference with contract, breach of contract, breach of covenant of good faith and fair
dealing, assault, civil conspiracy, negligence, and negligent hiring and retention.
Again, defendants moved to dismiss. This time, the district court granted the motion and
dismissed Warman’s federal claims with prejudice. Upon dismissal of all federal claims, the
1Warman also alleged a Second Amendment violation. He forfeited that claim at oral argument, so we do
not address it here.

-- 5 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 6
district court declined to exercise supplemental jurisdiction over Warman’s state claims.
Warman timely appealed.
II.
We review grants of motions to dismiss de novo. Nugent v. Spectrum Juv. Just. Servs.,
72 F.4th 135, 138 (6th Cir. 2023). In doing so, we accept all well-pleaded allegations in the
complaint as true and view the facts in the light most favorable to the plaintiff. Courtright v.
City of Battle Creek, 839 F.3d 513, 518 (6th Cir. 2016). To survive a motion to dismiss, the
complaint must present facts that, if accepted, “sufficiently ‘state a claim to relief that is
plausible on its face.’” Coley v. Lucas County, 799 F.3d 530, 537 (6th Cir. 2015) (quoting Bell
Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007) and Ashcroft v. Iqbal, 556 U.S. 662, 678
(2009)). We “must reverse the district court’s dismissal unless it appears beyond doubt that the
plaintiff can prove no set of facts in support of his claim which would entitle him to relief.”
Meriwether v. Hartop, 992 F.3d 492, 498 (6th Cir. 2021) (internal citations and quotation marks
omitted).
Warman’s federal causes of action can be grouped into two categories: three claims
brought under 42 U.S.C. § 1983 and one claim brought under the Rehabilitation Act, 29 U.S.C.
§ 793. We examine each category in turn, and then consider the district court’s declination of
supplemental jurisdiction over Warman’s state law claims.
III.
We begin with Warman’s three claims under 42 U.S.C. § 1983. We scrutinize the
dismissal of actions brought under civil rights statutes like § 1983 with “special care.” Inner
City Contracting, LLC v. Charter Twp. of Northville, 87 F.4th 743, 754 (6th Cir. 2023) (citation
omitted). To sue under § 1983, a plaintiff must show that he was denied a constitutional right,
and that the deprivation was caused by defendants acting under color of state law. Carl v.
Muskegon County, 763 F.3d 592, 595 (6th Cir. 2014).
Warman alleges the denial of his rights against unlawful detention under the Fourth
Amendment, to free religious exercise under the First Amendment, and to equal protection under

-- 6 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 7
the Fourteenth Amendment. The district court determined that Warman failed to establish a
constitutional violation in all three claims. Examining each, we find that only Warman’s
unlawful detention claim merits reconsideration. We begin there.
A.
1.
The Fourth Amendment, made applicable to the states through the Fourteenth
Amendment, prohibits law enforcement officers from seizing an individual “except after
establishing probable cause that the individual has committed, or is about to commit, a crime.”
Radvanksy v. City of Olmsted Falls, 395 F.3d 291, 302 (6th Cir. 2005) (citation omitted).
“[A] consensual encounter becomes a seizure when ‘in view of all the circumstances surrounding
the incident, a reasonable person would have believed that he was not free to leave.’” United
States v. Jones, 562 F.3d 768, 772 (6th Cir. 2009) (quoting United States v. Mendenhall, 446
U.S. 544, 554 (1980)).2
Bringing his unlawful detention claim against MJPD, Koopman, and Koo, Warman
alleges that MSJPD officers seized him at various points.3 His only substantive allegation stems
from his detention by Koopman and Koo at the campus police station for approximately an hour.
Considering the totality of the circumstances, Warman has plausibly alleged that he was seized
for Fourth Amendment purposes during that incident. While Warman arrived at the station
voluntarily, he was then told that he was not free to leave until Elliott arrived, and we have
previously held that a reasonable person would not feel free to leave when directed by police to
remain. See United States v. Richardson, 385 F.3d 625, 630 (6th Cir. 2004). Koopman and Koo
2Relying on an unpublished decision, the district court used several factors outlined in United States v.
Swanson, 341 F.3d 524 (6th Cir. 2003) to determine whether a reasonable person in Warman’s circumstances would
feel free to leave. But Swanson outlines factors for determining whether a defendant was subject to custodial
interrogation with respect to a Fifth Amendment claim. Id. at 528–29. While some of our unpublished decisions
have conflated these tests, our binding precedent clarifies that “Fourth Amendment seizure and Fifth Amendment
custody analyses are different.” Lawson v. Creely, 137 F.4th 404, 416 (6th Cir. 2025); see also United States v.
Salvo, 133 F.3d 943, 949 (6th Cir. 1998).
3This count also appears to assert a First Amendment retaliation claim. But since Warman does not
develop that argument, we deem it waived and construe the count as raising only a Fourth Amendment unlawful
detention claim.

-- 7 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 8
also took Warman into the back room of the station, as opposed to the front office or another
public space where he might have felt empowered to walk away. See Mendenhall, 446 U.S. at
555. And it is also plausible that a reasonable person in Warman’s circumstances would not
have felt free to terminate the encounter given the officers’ hostile “language [and] tone of
voice,” including swearing and verbal disparagements. Id. at 554.
The defendants argue and the district court determined that a reasonable person in
Warman’s position would have felt free to leave. Warman, however, specifically alleges that
“Koo and Koopman took [] Warman into a back room of the campus police station and would
not allow him to leave . . . .” (Second Am. Compl., R. 18, PageID 321 (emphasis added).) This
is a factual allegation—not a conclusory legal statement.
Defendants also maintain that Koopman and Koo acted as fellow veterans concerned for
Warman’s wellbeing and only intended to encourage Warman to get vaccinated. That may be
true. But a “police officer’s subjective intent in detaining an individual is irrelevant so long as
that intent is not conveyed to the individual in a way that results in the individual believing that
he or she is not free to leave.” United States v. Campbell, 486 F.3d 949, 954 (6th Cir. 2007).
Since a reasonable person would not feel free to leave when directed by police to remain,
Warman was seized for Fourth Amendment purposes. See Richardson, 385 F.3d at 630. And, as
Warman had not committed any crime, was not suspected to have committed any crime, and had
not even violated the university’s vaccine policy at that time, the officers lacked probable cause.
Thus, he plausibly established a denial of his Fourth Amendment rights. Of course, further
evidence may reveal otherwise. But at this juncture, we must consider Warman’s allegations to
be true.
2.
Having determined that Warman has alleged facts showing a plausible violation of his
Fourth Amendment rights, we examine whether Warman properly pleaded the claim against a
state actor. See Howell v. Father Maloney’s Boys’ Haven, Inc., 976 F.3d 750, 752 (6th Cir.
2020). As noted earlier, Warman brings his Fourth Amendment claim against MSJPD,
Koopman, and Koo. First, we address whether MSJPD is a legal entity capable of being sued in

-- 8 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 9
its own right. Deciding that it is not, we then evaluate whether Warman has established
Koopman’s and Koo’s liability under § 1983. Finally, we consider the officers’ qualified
immunity defense.
i.
For an entity that is not an individual or a corporation, the “[c]apacity to sue or be
sued[,]” and therefore be deemed sui juris, is generally governed “by the law of the state where
the court is located[.]” Fed. R. Civ. P. 17(b)(3). To be considered sui juris in Ohio, a party must
have “full capacity and rights to sue or be sued.” Urb. Necessities 1 Stop Shop, LLC v. City of
Cleveland, No. 1:22-CV-2014, 2023 WL 6383825, at *2 (N.D. Ohio Sept. 29, 2023) (citing
Mollette v. Portsmouth City Council, 863 N.E.2d 1092, 1094 (Ohio Ct. App. 2006)).
MSJPD “is the police and public safety department of MSJU[.]” (Second Am. Compl.,
R. 18, PageID 313.) It is also a state-commissioned law enforcement agency, operating under
Ohio Revised Code § 1713.50, a statute which empowers a private college or university to
establish a campus police department. Although confined to campus property, officers operating
under § 1713.50 are “vested . . . with the same powers and authority that are vested in a police
officer of a municipal corporation or a county sheriff[.]” Ohio Rev. Code § 1713.50 (C).
Warman argues that, as a state-commissioned law enforcement agency, MSJPD is a
public entity subject to suit. Defendants respond that, as a subdivision of MSJU and under its
control, MSJPD is not sui juris. The district court agreed with the defendants, citing to circuit
precedent that holds, as subdivisions of their municipalities, municipal police departments and
sheriff’s offices are not sui juris.
Indeed, police departments are generally not sui juris under Ohio law. See, e.g., Petty v.
County of Franklin, 478 F.3d 341, 347 (6th Cir. 2007) (noting that, “under Ohio law, a county
sheriff’s office is not a legal entity capable of being sued for purposes of § 1983”) (abrogated on
other grounds by Bailey v. City of Ann Arbor, 860 F.3d 382 (6th Cir. 2017)); Carmichael v. City
of Cleveland, 571 F. App’x 426, 435 (6th Cir. 2014) (collecting cases). Rather, they are “sub-
units” of the municipalities or counties that they serve. Jones v. Marcum, 197 F. Supp. 2d 991,
997 (S.D. Ohio 2002). Like a municipal police department is a sub-unit of its municipality, a

-- 9 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 10
private campus police department is a sub-unit of its university and “merely [a] vehicle[] through
which the [university] fulfills its policing functions.” Williams v. Dayton Police Dept., 680 F.
Supp. 1075, 1080 (S.D. Ohio 1987). Ohio Rev. Code § 1713.50 stipulates that a campus police
department established under the statute is created, controlled, staffed, and insured by the
university’s board of trustees. Ohio Rev. Code § 1713.50(B)–(D). And, even if we considered
private campus police departments as akin to other university offices, university subdivisions are
not sui juris in Ohio, and therefore, plaintiffs cannot sue them separately from the university
itself. See, e.g., Winkle v. Loranger, No. 3:14-CV-020, 2014 WL 1573654, at *4 (S.D. Ohio
Apr. 17, 2014). Federal courts have accordingly dismissed claims brought against university
subdivisions. Id.
The district court thus correctly determined that MSJPD is not a legal entity subject to
suit; MSJU is the proper defendant. See Fleck v. Trs. of Univ. of Pa., 995 F. Supp. 2d 390, 402
(E.D. Pa. 2014) (determining that a private university’s police department is “not an entity
capable of being sued” and the “[u]niversity itself . . . is the proper defendant for purposes of a
§ 1983 suit”). But Warman does not name MSJU in his Fourth Amendment claim in this
lawsuit.4
4Warman does, however, sue Koopman and Koo in their individual and official capacities. An official-
capacity suit “is, in all respects other than name, to be treated as” a suit against the entity “of which [the named
defendant] is an agent.” Kentucky v. Graham, 473 U.S. 159, 165–66 (1985) (citation omitted). Koopman and Koo
work for MSJU, so we must treat the official-capacity suit against them as a suit against MSJU. A private company
whose employees “perform a traditional state function” may be “sued under § 1983 as one acting under color of
state law.” Rouster v. County of Saginaw, 749 F.3d 437, 453 (6th Cir. 2014) (quoting Street v. Corrections Corp. of
Am., 102 F.3d 810, 814 (6th Cir.1996)). But it “cannot be held liable on the basis of respondeat superior or
vicarious liability.” Id. Rather, drawing from the standard the Supreme Court created for municipal liability in
Monell v. Department of Social Services, 436 U.S. 658 (1978), we have held that a plaintiff bringing a § 1983 suit
against a private company must prove that his “constitutional rights were violated” and that the company’s “policy
or custom . . . was the moving force behind” the violation. Savoie v. Martin, 673 F.3d 488, 494 (6th Cir. 2012)
(citation omitted). “All other circuits that have addressed the issue have reached the same conclusion, extending the
Monell standard to private corporations.” Shields v. Illinois Dep’t. of Corr., 746 F.3d 782, 790, 790 n.2 (7th Cir.
2014) (collecting cases from the First, Second, Third, Fourth, Sixth, Eighth, Ninth, Tenth, and Eleventh Circuits);
see also Maniaci v. Georgetown Univ., 510 F. Supp. 2d 50, 62 (D.D.C. 2007) (noting that “various circuits have
applied Section 1983 and its limitations as set forth in Monell to private institutions such as Georgetown University
where such private institutions employ” actors who wield state power). Here, as we elsewhere explain, Koopman
and Koo violated Warman’s Fourth Amendment rights by detaining him at the campus police station. But Warman
has not even attempted to show that MSJU had a policy or custom of unlawful detention. Indeed, Warman does not
cite the Monell standard in his brief or explain that it applies here. Instead, Warman’s Fourth Amendment
arguments focus solely on the officers’ unlawful conduct.

-- 10 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 11
Resisting this outcome, Warman relies on an Ohio Supreme Court case, State ex rel.
Schiffbauer v. Banaszak, 33 N.E.3d 52 (Ohio 2015), for the proposition that MSJPD is a public
office and therefore sui juris. In Banaszak, the Ohio Supreme Court held that the police
department of a private university established under Ohio Rev. Code § 1713.50(B) constituted a
public office that could be compelled to produce public records pursuant to Ohio’s Public
Records Act, even if the private university itself could not be compelled to do so. 33 N.E.3d at
55. Ohio courts, however, have noted that whether a public office is sui juris for the purposes of
the special statutory proceeding defined in the Ohio Public Records Act is a distinct question
from that entity’s sui juris status in other contexts. See, e.g., Barnes v. City of Cleveland Div. of
Recs. Admin., 167 N.E.3d 51, 57 (Ohio Ct. App. 2021).
We recognize that the campus police department of a private university differs from a
municipal police department in important ways, particularly for plaintiffs like Warman seeking
relief under § 1983. Had Warman been detained by a municipal department, he could have sued
the municipality, which is a state actor. Yet, despite Ohio law endowing campus officers with
the same powers as municipal police officers, the appropriate sui juris entity for a campus police
department is a private university. This complication, however, does not preclude Warman from
obtaining relief under § 1983, as private individuals or entities may still be considered state
actors for § 1983 purposes.
We therefore affirm the district court’s dismissal of all claims against MSJPD on the
basis that it is not an entity subject to suit.
ii.
We next consider whether Warman has carried his burden of showing that the remaining
defendants—Koopman and Koo—are state actors and therefore subject to liability under § 1983.
See Inner City, 87 F.4th at 757; Howell, 976 F.3d at 752. He has met his burden.
Private individuals may be considered state actors for the purposes of § 1983 actions if
they “exercise power ‘possessed by virtue of state law’ and if they are ‘clothed with the authority
of state law.’” Carl, 763 F.3d at 595 (quoting United States v. Classic, 313 U.S. 299, 326
(1941)). We ask whether the private individual’s “conduct is fairly attributable to the State.”

-- 11 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 12
Howell, 976 F.3d at 752 (quoting Filarsky v. Delia, 566 U.S. 377, 383 (2012) (internal quotation
marks omitted)). And we can also inquire: (1) whether the state compelled the individual’s
conduct (“the state-compulsion test”); (2) whether a symbiotic relationship existed between the
state and the individual (“the nexus test”); and (3) whether the individual engaged in an action
traditionally handled exclusively by the state (“the public-function test”). Nugent, 72 F.4th at
140 (internal citation omitted); Ciraci v. J.M. Smucker Co., 62 F.4th 278, 281 (6th Cir. 2023).
While the district court determined that Koopman and Koo were not state actors with
respect to Warman’s free exercise and equal protection claims, it did not explicitly address
whether Koopman and Koo qualified as state actors with respect to Warman’s Fourth
Amendment claim, dismissing the claim on the basis that it was barred by qualified immunity.
Warman reads the district court’s order as establishing that Koopman and Koo are not state
actors. We make explicit what the district court did not: even as officers of a private university’s
campus police department, Koopman and Koo acted under color of state law and are therefore
subject to § 1983 liability. See, e.g., Bartell v. Lohiser, 215 F.3d 550, 556 (6th Cir. 2000) (“It is
well settled that private parties that perform fundamentally public functions . . . are regarded as
acting ‘under the color of state law’ for purposes of § 1983.” (citation omitted)).
First, a brief examination of the state statute that delegates police power to MSJPD
reveals that Ohio clothed MSJPD’s officers with the authority of state law. When examining the
powers granted to campus police officers by Ohio Rev. Code § 1713.50, the Ohio Supreme Court
observed in Banaszak that campus police officers operating pursuant to the statute are “sworn,
state-certified police officers who exercise plenary police power[.]” 33 N.E.3d at 52–53. Like
the campus police department in that case, MSJPD
exercises a function of government, namely the basic police power of enforcing
laws and maintaining the peace within its jurisdiction. Its officers therefore have
the power to search and confiscate property, to detain, search, and arrest persons,
and to carry deadly weapons.
Id. at 54. Indeed, § 1713.50 expressly vests each member of a campus police department
appointed under it “with the same powers and authority that are vested in a police officer of a
municipal corporation or a county sheriff” and permits them to exercise,

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 13
concurrently with the law enforcement officers of the political subdivisions in
which the private college or university is located, the powers and authority
granted to them . . . to preserve the peace, protect persons and property, enforce
the laws of [Ohio], and enforce the ordinances and regulations of the political
subdivisions in which the private college or university is located[.]
Ohio Rev. Code § 1713.50(C). Consequently, when engaging in law enforcement activities
pursuant to the statute, MSJPD officers “exercise power possessed by virtue of state law
and . . . are clothed with the authority of state law.” Carl, 763 F.3d at 595 (internal citation and
quotation marks omitted).
Our traditional state actor inquiry leads to the same outcome. The public function test is
the most useful of the three inquiries for these circumstances, and our precedent on private
security guards is analogous. For example, in Romanski v. Detroit Ent., L.L.C., 428 F.3d 629,
637 (6th Cir. 2005), we decided that “[w]here private security guards are endowed by law with
plenary police powers such that they are de facto police officers, they may qualify as state actors
under the public function test.” The court relied on “[t]he fact that [the state] delegated a part of
the police power to licensed private security guards, which it had traditionally and exclusively
reserved for itself,” to find state action. Lindsey v. Detroit Ent., LLC, 484 F.3d 824, 831 (6th Cir.
2007) (discussing Romanski). In other words, what differentiates a private security force
considered a state actor from a purely private security force is some “identifiable police power”
that is “not possessed by citizens of [a state] at large, but instead reside[s] only in the state, its
agents, and those persons who the state empower[s] and regulate[s] by statute.” Id.; see also
Payton v. Rush-Presbyterian St. Luke’s Med. Ctr., 184 F.3d 623, 629 (7th Cir. 1999) (“[I]f the
state cloaks private individuals with virtually the same power as public police officers, and the
private actors allegedly abuse that power to violate a plaintiff’s civil rights, that plaintiff’s ability
to claim relief under § 1983 should be unaffected.”).
Like the private security guards in Romanski, MSJPD’s officers are subject to certain
statutory limitations and the oversight of the university, but they exercise police powers that
typically reside only in the state. Moreover, MSJPD holds itself out as being “a commissioned
law enforcement agency by the State of Ohio, that operates under [Ohio Rev. Code §] 1713.50”
on its website. MSJ Police Department and Public Safety, Mount St. Joseph University,

-- 13 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 14
https://www.msj.edu/student-life/public-safety-campus-police/ (last visited May 7, 2025). Its
website includes a photograph of its uniformed officers and its vehicles, which are emblazoned
with “POLICE” in large letters. Id. MSJPD officers, therefore, both possess the same powers
and appearance of public officers, even if the “uniforms, vehicles, and badges of members of a
campus police department” are required to be “distinct from those of the law enforcement
agencies of the political subdivisions which the private [university] . . . is located.” Ohio Rev.
Code § 1713.50(B). Where a private university’s officers violate a plaintiff’s civil rights, a
“plaintiff’s ability to claim relief under § 1983 should be unaffected.” See Payton, 184 F.3d at
629.
The Third Circuit has held similarly in the campus police context. In Henderson v.
Fisher, 631 F.2d 1115 (3d Cir. 1980), it determined that the University of Pittsburgh’s campus
police qualified as state actors, in part, because the “Pennsylvania legislature ha[d] delegated to
the campus police of the University of Pittsburgh the very powers which the municipal police
force of Pittsburgh possesses.” Id. at 1118. Consequently, the Third Circuit reasoned that “the
delegation of police powers, a government function, to the campus police buttress[ed] the
conclusion that the campus police act under color of state authority.” Id.; see also Fleck, 995 F.
Supp. 2d at 400 (determining that campus police officers, endowed by law with plenary police
powers, acted as state actors and were subject to liability under § 1983).
Accordingly, where Koopman and Koo “exercised power possessed by virtue of state law
and made possible only because [they were] clothed with the authority of state law[,]” they meet
the “traditional definition” of acting under color of state law. See West v. Atkins, 487 U.S. 42, 49
(1988) (internal citation and quotation marks omitted). Koopman and Koo did so when
detaining Warman at the campus police station. Koopman and Koo thus qualify as state actors
subject to § 1983 liability for Warman’s Fourth Amendment claim.
iii.
Based on the foregoing, Warman’s complaint properly pleads a violation of his Fourth
Amendment rights by state actors. Nonetheless, defendants argue that the claim is barred by
qualified immunity, and the district court agreed. “Qualified immunity shields government

-- 14 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 15
officials in the performance of discretionary functions from standing trial for civil liability unless
their actions violate clearly established rights.” DiLuzio v. Village of Yorkville, 796 F.3d 604,
608 (6th Cir. 2015) (citing Harlow v. Fitzgerald, 457 U.S. 800, 818 (1982)). We review a
district court’s finding that qualified immunity applied to officers’ conduct de novo. Pleasant
View Baptist Church v. Beshear, 78 F.4th 286, 295 (6th Cir. 2023).
As a threshold issue, it is unclear whether Koopman and Koo are entitled to raise a
qualified immunity defense as privately employed campus police officers. “Section 1983 creates
a species of tort liability that on its face admits of no immunities.” Wyatt v. Cole, 504 U.S. 158,
163 (1992) (citation omitted). Instead, the Supreme Court has “accorded immunity where a
‘tradition of immunity was so firmly rooted in the common law and was supported by such
strong policy reasons that Congress would have specifically so provided had it wished to abolish
the doctrine.’” Richardson v. McKnight, 521 U.S. 399, 403 (1997) (quoting Wyatt, 504 U.S. at
164) (cleaned up); see also Filarsky, 566 U.S. at 385–89. That analysis as applied to various
privately employed state actors seeking the protection of qualified immunity has yielded
different answers, in both the Supreme Court and in this circuit. Compare Filarsky, 566 U.S. at
393–94 (a private individual retained by the government to conduct an official investigation may
assert qualified immunity), with Richardson, 521 U.S. at 401 (prison guards employed by a
private prison management firm may not assert qualified immunity), Harrison v. Ash, 539 F.3d
510, 522 (6th Cir. 2008) (nurses employed by a private medical provider to provide medical
services in prisons and jails may not assert qualified immunity), and McCullum v. Tepe, 693 F.3d
696, 704 (6th Cir. 2012) (a private doctor employed by the government may not assert qualified
immunity).
It is “well established” that public police officers may assert qualified immunity. United
Pet Supply, Inc. v. City of Chattanooga, 768 F.3d 464, 479 (6th Cir. 2014). But, although
MSJPD is a state-commissioned law enforcement agency, it is also a sub-unit of a private
university. Therefore, it is not apparent whether its officers should be considered akin to public
police officers who may assert qualified immunity or considered private actors endowed with
plenary police powers by Ohio law and so potentially ineligible. No clear authority from this
court or the Supreme Court offers an answer. See Hoggard v. Rhodes, 141 S. Ct. 2421, 2422

-- 15 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 16
(2021) (Thomas, J., respecting denial of certiorari) (“[W]hy should university officers, who have
time to make calculated choices about enacting or enforcing unconstitutional policies, receive the
same protection as a police officer who makes a split-second decision to use force in a dangerous
setting? We have never offered a satisfactory explanation to this question.”). Therefore, as other
federal courts have observed, “the question [of] whether university-employed [] police can even
assert qualified immunity is a complicated one.” Wheeler v. Am. Univ., 619 F. Supp. 3d 1, 22
(D.D.C. 2022).
The framework to resolve this question offered by the Supreme Court in Richardson and
Filarsky “demands a fact-intensive analysis.” United Pet Supply, 768 F.3d at 479. But neither
side meaningfully engages with the required inquiry. When asserting qualified immunity below,
the defendants did not cite to any authority that establishes their entitlement to a qualified
immunity defense. Warman briefly challenged that entitlement in his reply below, citing Justice
Thomas’s concurrence in Hoggard, but going no further. 141 S. Ct. at 2422. The district court,
for its part, did not address the issue.5
The arguments made before us are similarly sparse. Warman again gestures to the mere
existence of the issue but offers no developed argument following the framework laid out in
Richardson and Filarsky. “It is not sufficient for a party to mention a possible argument in the
most skeletal way, leaving the court to . . . put flesh on its bones.” McPherson v. Kelsey, 125
F.3d 989, 995–96 (6th Cir. 1997) (quoting Citizens Awareness Network, Inc. v. U.S. Nuclear
Regul. Comm’n, 59 F.3d 284, 293–94 (1st Cir. 1995)). As such, “[i]ssues adverted to in a
perfunctory manner, unaccompanied by some effort at developed argumentation,” as here, “are
deemed waived.” See id.
We largely do not consider waived arguments. See United States v. Ellison, 462 F.3d
557, 560 (6th Cir. 2006). Only “exceptional cases” justify deviating from this general rule, for
5In its analysis of Warman’s free exercise and equal protection claims, the district court considered whether
Koopman and Koo constitute state actors and determined that they do not. Addressing Warman’s Fourth
Amendment claim, however, the district court proceeded directly to Koopman and Koo’s qualified immunity
defense without first concluding that Koopman and Koo are state actors. If the district court did so by assuming that
Koopman and Koo were the equivalent of public police officers, it did not explain how they could be considered
state actors for the Fourth Amendment claim but not the others.

-- 16 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 17
example, occasions where “failing to consider the argument would result in a ‘plain miscarriage
of justice.’” Id. (quoting Pinney Dock & Transp. Co. v. Penn Cent. Corp., 838 F.2d 1445, 1461
(6th Cir. 1988)). If we agreed with the district court that Warman fails to overcome Koopman’s
and Koo’s qualified immunity defense, this would likely be that rare case. While the district
court “did not expressly state” that Koopman and Koo were eligible to raise a qualified immunity
defense, “such a conclusion was necessarily implied by the court’s ruling” that qualified
immunity barred Warman’s Fourth Amendment claim. Id. at 560. If Koopman and Koo are in
fact not even eligible for qualified immunity, “failing to consider the issue would result in a plain
miscarriage of justice—namely, allowing a conclusion of law to stand that is clearly in error.”
Id. at 561.
But, even if we assume without deciding that Koopman and Koo can raise a qualified
immunity defense, that defense—briefed fully by both parties—fails on this motion to dismiss.
It is “generally inappropriate for a district court to grant a [Rule] 12(b)(6) motion to dismiss on
the basis of qualified immunity.” Wesley v. Campbell, 779 F.3d 421, 433 (6th Cir. 2015). We
make an exception, however, where plaintiff’s allegations fail to “state a claim of [a] violation of
clearly established law.” Johnson v. Moseley, 790 F.3d 649, 653 (6th Cir. 2015) (quoting
Mitchell v. Forsyth, 472 U.S. 511, 526 (1985)).
As discussed above, Warman plausibly alleges a violation of his Fourth Amendment
rights. So, we must consider whether “the right was so clearly established that a reasonable
official would understand that the particular conduct at issue violated that right.” Crockett v.
Cumberland Coll., 316 F.3d 571, 579 (6th Cir. 2003). Though a plaintiff need not point to a case
with an identical fact pattern, a plaintiff must identify sufficiently analogous cases from which a
reasonable official would understand that his conduct violated the plaintiff’s constitutional right.
Pleasant View, 78 F.4th at 295.
Warman does so. The right to be free from seizure without probable cause is “clearly
established.” See Tlapanco v. Elges, 969 F.3d 638, 648 (6th Cir. 2020); see also Centanni v.
Eight Unknown Officers, 15 F.3d 587, 592 (6th Cir. 1994). And, as discussed above, Koopman
and Koo lacked probable cause to detain Warman on this record.

-- 17 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 18
Accordingly, we reverse the district court’s grant of qualified immunity. In doing so, we
leave open the question of whether Koopman and Koo may assert qualified immunity in the first
instance. While resolving the question may “materially advance” the progress of litigation, the
issue was not “presented with sufficient clarity and completeness” below to justify us exercising
our “limited” discretion to reach it here. Pinney, 838 F.2d at 1461; see also In re Hood, 319 F.3d
755, 760 (6th Cir. 2003). If Koopman and Koo again raise a qualified immunity defense at a
later stage in this litigation, the district court should then resolve the question.
B.
We next consider Warman’s free exercise claim. The Free Exercise Clause, applied to
the states through the Fourteenth Amendment, protects against both direct and indirect coercion
or penalties on the free exercise of religion. See Dahl v. Bd. of Trs. of W. Mich. Univ., 15 F.4th
728, 731 (6th Cir. 2021). But not every burden on religious exercise is unconstitutional. Id. at
733.
Warman brings his free exercise claim against MSJU, MSJPD, Elliott, Metzger,
Ellerman, Hinzman, Koopman, and Koo. He alleges that these defendants “acted to discriminate
and/or retaliate against [] Warman for [] freely exercising his religious preference, based upon
his sincerely held beliefs, not to be vaccinated.” (Second Am. Compl., R. 18, PageID 331.)
Warman’s free exercise allegations fall into two categories: (1) Koopman’s and Koo’s
disparaging remarks about Warman’s religion, and (2) the denial of Warman’s requested
religious exemption under MSJU’s vaccine policy, as carried out by MSJU administrators.
For the first category, Warman has not shown that his religious exercise was burdened.
“While [Warman] has presented facts suggesting that [he] was exposed to religious information
[by Koopman and Koo] with which [he] did not agree, [he] has given no indication that the
information coerced [him] into doing or not doing anything.” Nikolao v. Lyon, 875 F.3d 310,
316 (6th Cir. 2017). And while he also presented facts that Koopman and Koo disparaged his
religious beliefs, “actions that merely offend or cast doubt on religious beliefs do not on that
account violate free exercise.” Mozert v. Hawkins Cnty. Bd. of Educ., 827 F.2d 1058, 1068 (6th

-- 18 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 19
Cir. 1987) (quoting Grove v. Mead School Dist. No. 354, 753 F.2d 1528, 1543 (9th Cir. 1985)).
Rather, “[a]n actual burden on the profession or exercise of religion is required.” Id.
For the second category, Warman has not shown that the defendants involved in the
exemption process under MSJU’s vaccine policy were “engaged in state action.” See Lindke v.
Freed, 601 U.S. 187, 195 (2024). Warman alleges that MSJU’s vaccine policy was implemented
by school administrators Karen Elliott, Amy Metzger, Paige Ellerman, and Nancy Hinzman.
(See Second Am. Compl., R. 18, PageID 311, 320 (stating that these defendants “created and
acted to carry out” the University’s vaccine policy, including “assessing religious exemption
requests”).) But MSJU is a private school, and all the administrators alleged to be involved in
handling Warman’s exemption requests were private employees.
Warman argues only that the administrators are state actors “with respect to their
direction of MSJPD.” (Appellant Br. 18–19.) As Warman sees it, Koo and Koopman were state
actors because they exercised state police power “traditionally exclusively reserved to the state,”
and MSJU administrators were state actors because they allegedly “control[led] and direct[ed]”
Koo and Koopman. Id. (quotations omitted). To be sure, as we previously explained, we believe
that Koo and Koopman engaged in state action when they exercised state police power to detain
Warman. See supra Part III.A.2.ii. But we must evaluate whether “the specific conduct of
which the plaintiff complains” is state action for each of Warman’s claims. Lindke, 601 U.S. at
767 (citation omitted). With regard to his claim that MSJU’s vaccine policy violated his free
exercise rights, the “specific conduct” at issue, id., is MSJU’s denial of Warman’s religious
exemption. Warman does not explain how that denial—a private administrative decision made
by the private employees of a private university—is an exercise of state power. Indeed, that
denial is wholly separate from MSJPD’s police activities.
Consequently, we affirm the district court’s dismissal of Warman’s free exercise claim as
to all defendants.
C.
Warman’s equal protection claim fares no better. The Equal Protection Clause prohibits
state actors from “intentionally treat[ing] one differently than others similarly situated without

-- 19 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 20
any rational basis for the difference.” TriHealth, Inc. v. Bd. of Comm’rs, 430 F.3d 783, 788 (6th
Cir. 2005).
Warman brings his equal protection claim against MSJU, MSJPD, Elliott, Metzger,
Ellerman, Hinzman, Koopman, and Koo. His complaint states that “[n]umerous other students
were on campus, including others who were unvaccinated, and none received the treatment
provided to [] Warman[.]” (Second Am. Compl., R. 18, PageID 323.) But he fails to “allege,
with particularity, facts that demonstrate what each defendant did” to single him out or treat him
differently from other similarly situated MSJU students or employees. See Ondo v. City of
Cleveland, 795 F.3d 597, 610 (6th Cir. 2015) (citation omitted). A “critical aspect of the § 1983
. . . universe is that to be held liable, a plaintiff must demonstrate ‘that each [state actor]
defendant, through the [defendant’s] own individual actions, has violated the Constitution.’”
Robertson v. Lucas, 753 F.3d 606, 615 (6th Cir. 2014) (quoting Iqbal, 556 U.S. at 676).
Warman’s equal protection claim largely consists of nonspecific allegations that various
defendants, through their mere involvement in enacting the university’s vaccine policy, violated
his constitutional rights by attributing wrongful acts to the whole group. This is insufficient. See
Ondo, 795 F.3d at 611.
Warman thus fails to plausibly allege that any defendant violated his rights under the
Equal Protection Clause. Since establishing the denial of a constitutional right is one of the “two
essential elements” required to sustain a § 1983 claim, Graham v. Nat’l Collegiate Athletic
Ass’n, 804 F.2d 953, 957 (6th Cir. 1986), we affirm the district court’s dismissal of Warman’s
equal protection claim as to all defendants without proceeding to the next step of the analysis.
IV.
Next, we consider Warman’s disability discrimination claim under 29 U.S.C. § 793 et
seq. Section 793 concerns discrimination in employment, and Warman was not an MSJU
employee. For the sake of judicial expediency, defendants overlooked the error and construed
Warman’s complaint as making out a claim under 29 U.S.C. § 794 (“Section 504”). The district
court, dismissing any § 793 claim with prejudice, also addressed whether Warman made out a

-- 20 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 21
claim under Section 504 and determined that he had not. On appeal, Warman proceeds as if he
had alleged a claim under Section 504.
Even when pleading under the correct provision, the claim falls short. Section 504 of the
Rehabilitation Act of 1973 prohibits “any program or activity receiving Federal financial
assistance” from discriminating against an “otherwise qualified individual with a
disability . . . solely by reason of her or his disability[.]” 29 U.S.C. § 794(a). To properly state a
claim for relief under Section 504, a plaintiff must show “(1) that he is disabled; (2) that he was
otherwise qualified for the position; (3) that he was excluded solely by reason of his disability;
(4) and that the relevant program is receiving federal financial assistance.” Doe v. Salvation
Army in the U.S., 685 F.3d 564, 567 (6th Cir. 2012) (internal citation and quotation marks
omitted).
Warman alleges that “at different times, in different ways, and in different combinations,
[the defendants] purposely discriminated against [] Warman based on his actual and/or perceived
disabilities.” (Second Am. Compl., R. 18, PageID 332.) Even setting aside the failure to plead
with particularity, Warman’s complaint fails to allege how MSJU or its employees discriminated
against him solely by reason of his disabilities when they refused his exemption request, even if
they disregarded a doctor’s note that apparently set out a medical need to avoid the vaccine.
Warman does not allege what medical condition caused him not to take the vaccine. And he also
does not allege that MSJU or its employees forced his withdrawal from the university for failing
to receive the vaccine—rather, Warman withdrew from the university prior to the date mandating
all students to demonstrate proof of vaccination.
Accordingly, we affirm the district court’s dismissal of Warman’s disability
discrimination claim against all defendants.

-- 21 of 23 --

No. 24-3042 Warman v. Mount St. Joseph Univ., et al. Page 22
V.
Warman also asks us to reinstate his state-law claims in light of the district court’s
decision to decline to exercise supplemental jurisdiction. We review a district court’s declination
of supplemental jurisdiction for an abuse of discretion. Veneklase v. Bridgewater Condos, L.C.,
670 F.3d 705, 709 (6th Cir. 2012).
The district court declined to exercise supplemental jurisdiction because it had dismissed
all federal claims. Because we reinstate Warman’s Fourth Amendment claim, that rationale no
longer applies. We therefore vacate the dismissal of Warman’s state-law claims against all
defendants but MSJPD and “remand the proceedings to the district court to allow it to address
the question of whether it wishes to exercise supplemental jurisdiction over the state law claims
given that a federal claim remains pending.” Veneklase, 670 F.3d at 716.
VI.
Finally, Warman contends that the district court abused its discretion by dismissing his
claims with prejudice and denying him leave to amend. A district court’s dismissal of a
complaint with prejudice is generally reviewed for abuse of discretion. Crosby v. Twitter, Inc.,
921 F.3d 617, 622 (6th Cir. 2019). While, ordinarily, a district court dismissing a claim with
prejudice must state its reasons for doing so, a plaintiff is first required to file a formal motion
for leave to amend the complaint. Id. at 627. It is, therefore, not an abuse of discretion for a
district court to dismiss a claim with prejudice if the party has not moved to amend or proposed
an amended complaint. CNH Am. LLC v. Int’l Union, United Auto., Aerospace & Agr.
Implement Workers of Am. (UAW), 645 F.3d 785, 795 (6th Cir. 2011).
Warman did not file a formal motion to amend. As such, the district court did not abuse
its discretion in denying him leave to amend. In any case, on appeal, Warman seeks leave to
amend specifically to clarify that Koopman and Koo told Warman that he was not free to leave.
Since Warman already plausibly alleged that he was not free to leave in his complaint, further
opportunity to draft his complaint would offer no additional evidence or argument for the district
court to consider. See, e.g., Libertarian Nat’l Comm., Inc. v. Holiday, 907 F.3d 941, 948 (6th
Cir. 2018).

part, and remanded in accordance with this opinion.
