    August 6, 2019
    KAYATTA, Circuit Judge.      In the wake of allegations that
    student James Haidak assaulted a fellow student, the University of
    Massachusetts at Amherst ("the university") suspended and then
    expelled    Haidak.      Seeking   compensatory     damages,   declaratory
    relief, and an injunction preventing the university from enforcing
    the expulsion, Haidak filed this suit against the university and
    several of its officials.     Following discovery, the district court
    entered summary judgment in the defendants' favor. Haidak appealed
    to this court.        For the following reasons, we find that the
    university violated Haidak's federal constitutional right to due
    process in suspending him for five months without prior notice or
    a fair hearing, but that it did not thereafter violate his rights
    in expelling him after providing a fair expulsion hearing.               We
    therefore affirm the dismissal of Haidak's complaint in part and
    otherwise vacate the judgment and remand for further proceedings.
    I.
    A.
    We begin by describing the student disciplinary process
    at the university, as specified in the version of the Code of
    Student Conduct (CSC) in effect during the 2012–2013 academic year.
    The   CSC   enumerated   disciplinary      and   academic   violations   and
    described the procedures the university employed to adjudicate
    suspected violations.      The CSC applied to conduct that occurred
    both on campus and "in other locations when the behavior distinctly
    - 3 -
    and directly affect[ed] the University community."   The university
    could file charges at the request of any student, faculty member,
    or staff member, or the university could initiate charges itself.
    The CSC called for the university to send an accused
    student a Notice of Charge.   The student then had at least forty-
    eight hours to request a Disciplinary Conference to discuss the
    alleged offense.    If the Notice of Charge involved a serious
    violation, and a university official determined that the accused
    student was a threat to self, others, or property, the CSC allowed
    university officials to impose an interim restriction such as a
    suspension.   Interim restrictions could be imposed without prior
    notice, although "whenever reasonably possible" a meeting would
    "be held prior to the imposition of interim restrictions" to inform
    the student of the "basis of the allegation" and give the student
    "the opportunity to present his or her own version of the facts."
    Any violation of an interim restriction could lead to further
    charges.
    The CSC established a Hearing Board, made up of three to
    five employees and students appointed by the Vice Chancellor for
    Student Affairs.   The Hearing Board adjudicated contested charges
    in proceedings in which the university bore the burden of proof by
    a preponderance of the evidence.       The Hearing Board was not
    required to "observe the rules of evidence observed by courts, and
    [could] exclude unduly repetitious or irrelevant evidence."   After
    - 4 -
    a hearing, the board would create a written summary of testimony,
    findings of fact, a decision, and a rationale, and then forward
    this record to the Dean of Students.               A designated university
    official would then render a written decision and sanction.                 The
    sanction was informed by, among other factors, the nature of the
    offense and the student's disciplinary record.
    A student could appeal the decision or the sanction to
    the University Appeals Board.         Possible grounds for appeal were:
    (1) "procedural error or irregularity which materially affected
    the decision"; (2) "[n]ew evidence not previously available which
    would   have   materially     affected       the   decision";    (3) lack    of
    "substantial evidence" supporting the decision; or (4) lack of
    support for the sanction imposed.          The Appeals Board would review
    the record and make a recommendation to the Vice Chancellor for
    Student Affairs, who would issue a final decision.
    B.
    Haidak and Lauren Gibney, both university students, were
    in a tumultuous romantic relationship beginning in 2012.                    The
    incident   that   triggered    the    initial      charges    against   Haidak
    occurred in the early morning hours of April 16, 2013, during a
    semester when Haidak and Gibney were studying abroad in Barcelona.
    Haidak and Gibney agree that, after the two got home from a club,
    they got in an argument that turned physical.                They dispute who
    hit whom first.   According to Gibney, Haidak put his hands around
    - 5 -
    her neck, pushed her onto the bed, hurt her by squeezing various
    pressure points, and grabbed her wrists and punched himself in the
    face with her fists.     According to Haidak, Gibney struck him, and
    he only restrained her to prevent her from continuing to hit him,
    slap him, and kick him in the groin.
    Later that day, Gibney's mother called the university to
    report that Haidak had physically assaulted her daughter.              Gibney
    followed up three days later by submitting a written report of the
    incident.      On   April 17,   Enku    Galaye,   the   Dean   of    Students,
    instructed Allison Berger, an Associate Dean of Students, to open
    a CSC case against Haidak. On April 19, 2013, Berger issued Haidak
    a Notice of Charge for violating two provisions of the CSC:
    (1) Physical Assault1 and (2) Endangering Behavior to Persons or
    Property.2    The notice included a no-contact order: "You are not
    to have any direct or indirect contact with [Gibney].                     This
    includes, but is not limited to comments, words or gestures in
    person,   through    postal   mail,    email,   text,   instant     messaging,
    social networking sites, or by having others . . . act on your
    1 The definition of physical assault applied by the Hearing
    Board without objection was "physical attack upon or physical
    interference with a person that causes that person to suffer actual
    physical injury."   Haidak v. Univ. of Mass. at Amherst, 
    299 F. Supp. 3d 242
    , 258 n.18 (D. Mass. 2018).
    2 The 2012–2013 CSC prohibited "[e]ndangering the safety of
    persons (self or others) or property, [and] any action that might
    lead to loss of life or serious physical harm to others . . . ."
    - 6 -
    behalf."   Haidak met with Berger on May 1, 2013.    He denied the
    allegations and followed up that same day with an email containing
    his version of the incident.
    Despite the no-contact order, Haidak and Gibney resumed
    contact almost immediately, both over the phone and in person.   On
    May 9, 2013, Gibney's mother discovered hundreds of calls and
    thousands of text messages from Haidak on the family's phone bill.
    When Gibney discussed these calls and texts with her mother, and
    with Berger later that same day, she failed to disclose that the
    contact had been largely welcomed and reciprocated.      On May 28,
    2013, Berger issued to Haidak a second Notice of Charge for
    (1) Harassment3 and (2) Failure to Comply with the Direction of
    University Officials.4    The second notice contained the same
    explicit directive not to contact Gibney.
    On June 3, 2013, Gibney and her mother met with Berger
    to complain about continued communications from Haidak, and the
    next day Gibney provided Berger a phone log that chronicled the
    calls and texts she had received from Haidak:   311 calls and 1,749
    text messages between April 24 and June 1.      Thirty-one of these
    3 Under the CSC, harassment meant "repeated use by one or more
    students of a written, verbal, or electronic expression or a
    physical act or gesture, or any combination thereof, directed at
    a person that places that person to be [sic] in fear for his or
    her physical safety."
    4 The CSC prohibited "[f]ailure to comply with the directions
    of University officials acting in performance of their duties."
    - 7 -
    calls occurred between May 28 and June 1, in violation of the no-
    contact order contained in the second Notice of Charge.5                      Gibney
    admitted to Berger that she "did unfortunately get comfortable
    with talking and therefore would respond some and answer a few
    calls." It later became clear that Gibney sent approximately seven
    hundred text messages to Haidak during that six-week period, with
    many messages after May 28.
    The university took no official action between June 4
    and June 17.          On June 17, Berger issued a third Notice of Charge
    for (1) Harassment and (2) Failure to Comply with the Direction of
    University Officials.            This time, the university also concluded,
    without       prior     notice       to   Haidak,   that     Haidak's    "behavior
    represent[ed] a direct and imminent threat to [his] safety and the
    safety of the University community" and warranted an immediate
    suspension.          The notice informed Haidak that he had the right to
    a meeting to discuss the suspension.
    Two     days   later,      on   June 19,     Berger    conducted    a
    telephonic disciplinary conference with Haidak and his father.
    They agreed that Haidak would submit a response to the allegations
    that he had violated the no-contact orders and harassed Gibney and
    that       Berger    would    then    decide   whether     Haidak    should   remain
    suspended pending his hearing for the assault charge.
    5
    Haidak maintains that he did not receive the second Notice
    of Charge until June 1.
    - 8 -
    During the June 19 call, Haidak also expressed interest
    in filing charges against Gibney for her violence against him
    during the Barcelona incident.             Berger told Haidak that he was
    free to file a charge, but that it was unlikely the university
    would address any charges against Gibney until after the conclusion
    of the disciplinary process against Haidak.
    On July 8, 2013, Haidak sent Berger an email detailing
    his side of the story and explaining that the communications in
    violation   of    the    no-contact      orders   were   mutual    and     welcome.
    Silence ensued (and the suspension continued) until August 5,
    2013,   when     the    university    notified    Haidak    that    the     interim
    suspension remained in place pending a hearing on the assault
    charge, which had yet to be scheduled.
    Over the summer of 2013, the university took no action
    to schedule a hearing for Haidak.            In fact, the university had no
    procedures in place that would have allowed it to conduct a hearing
    while   student        board   members     were   away     for    summer     break.
    Recruitment of new student members began on August 30, 2013, with
    applications due on September 13 and trainings running through
    September 27.
    On    September 1,       2013,    Haidak     withdrew        from   the
    university, concerned that "the lack of a timely Hearing Board
    date . . . meant that the complaint against him would not be
    addressed until several weeks into the new school year, at the
    - 9 -
    earliest."     Haidak v. Univ. of Mass. at Amherst, 
    299 F. Supp. 3d 242
    , 255 (D. Mass. 2018).       Haidak got an apartment in Amherst and
    he and Gibney maintained their off-and-on relationship.
    Two incidents that took place in mid- to late-September
    led Gibney to finally cut off communication with Haidak.          First,
    on September 14, Haidak -- intoxicated at the time -- called Gibney
    for a ride.        The two got into an argument, and Haidak threatened
    to kill himself and then exited the moving car.        Gibney called the
    police, and her mother reported the incident to Berger the next
    day.
    Gibney and her mother met with Berger on September 19,
    2013.   Gibney admitted that she had continued to maintain a
    relationship with Haidak, but said she no longer wanted contact
    with him.     Berger "explained that the no contact is in place for
    both her & James."        It is unclear whether this statement was a
    reminder that the no-contact order applied to Gibney as well or
    whether this was the first time Gibney received notice that she
    was subject to the no-contact order.           According to Berger, the
    university generally advised the protected party not to engage in
    contact, but that advice was "very different from a no contact
    directive as issued in an order or a letter to a student as part
    of the conduct process."
    The    second   incident   took   place   on   September 26.
    Apparently intoxicated, Haidak arrived at the bar where Gibney
    - 10 -
    worked.   He positioned himself uncomfortably close to Gibney until
    security eventually removed him from the premises.                 The next day,
    after notifying the university about the events of the previous
    night,    Gibney    sought    and    obtained     a     state-court      temporary
    restraining order against Haidak.
    On October 8, a state district court held an adversarial
    hearing to consider Gibney's application to extend the restraining
    order.    Gibney first testified that she and Haidak broke up in
    April when they left Barcelona, but then later acknowledged that
    she and Haidak had been "speaking."              When confronted with text
    messages she sent to a friend about her relationship with Haidak,
    Gibney further admitted that she had voluntarily interacted with
    Haidak after the no-contact order had been issued, including by
    having consensual sex with him as recently as mid-September.                    She
    also admitted that she had struck and bitten Haidak during the
    course of their relationship.         The state court declined to extend
    the restraining order.
    The    university   offered       Haidak    three    dates    for   the
    hearing and Haidak selected November 22, 2013.                  Haidak knew that
    he would not be present in Amherst that day and would have to
    participate by phone.        The university sent Haidak a handout on
    hearing procedures.       It described a new policy, instituted at the
    beginning   of     the   2013–2014   school     year,    under    which    charged
    students could no longer question other students directly, but
    - 11 -
    instead could submit proposed questions for the Board to consider
    posing to the witness.     Haidak submitted thirty-six questions he
    wanted the Hearing Board to ask Gibney.       Patricia Cardoso, the
    Assistant Dean of Students, pared this list down to sixteen.
    In the weeks preceding the Hearing Board meeting, Haidak
    and Cardoso also discussed the evidence Haidak wished to present
    to the Hearing Board.      Haidak sent Cardoso a transcript of the
    state-court restraining order hearing, as well as a photograph of
    a bite mark Gibney left on his arm in a previous altercation.    He
    also wanted his mother to testify about Gibney's prior acts of
    violence against him.     Cardoso did not permit the introduction of
    any of these three pieces of evidence.
    Four students and one staff chair sat on the Hearing
    Board that considered Haidak's charges.    Gibney attended in person
    while Haidak phoned in.    Haidak's attorney was present, though not
    allowed to do more than observe the hearing and consult with Haidak
    by phone. Both Haidak and Gibney had university-appointed advisors
    present.   Moving back and forth between Haidak and Gibney, the
    Hearing Board ultimately examined each student three times.      Of
    the dozens of questions the Board asked Gibney, none were worded
    identically to any on Haidak's pre-submitted list, but many were
    designed to elicit the same information.    The Board also examined
    the photos and statements submitted by each party, as well as text
    messages and phone logs.
    - 12 -
    The   Board   ultimately   found   Haidak   responsible   for
    assault and failure to comply with the no-contact orders, but not
    for endangerment or harassment.      The Board's report provided the
    following rationale:
    The board finds [Haidak] not responsible for
    [endangering behavior to persons or property],
    because his actions did not rise to a level
    violating this policy. However, his behavior
    was disproportionate to the actions he
    attributed to Gibney, and the board believes
    [Haidak] did cause physical harm to [Gibney's]
    wrists and arms based on the narratives and
    pictures presented in the hearing. As such,
    we find [Haidak] responsible for [physical
    assault].
    Regarding the second and third incidents, the
    board finds [Haidak] not responsible for
    [harassment] in both cases, as the contact
    after the April incident was mutual and non-
    threatening   according    to    both   parties.
    However, we find [Haidak] responsible for
    [failure to comply] in both cases because he
    still knowingly violated the directives of the
    university,   and   failed    to   address   any
    reservations he might have had with the
    appropriate official.
    David Vaillancourt, the Associate Dean of Students, found the
    outcome "consistent with the charges and based on substantial
    evidence."   After reviewing Haidak's disciplinary history, which
    included two prior violations of the CSC,6 Vaillancourt decided on
    6  In 2010, Haidak, while intoxicated, assaulted another
    student and pushed and spat on the resident advisor who broke up
    the altercation. Haidak was placed in protective custody because
    of his "level of intoxication," the "anger [he] demonstrated," and
    his "unwillingness to calm down."     He faced CSC violations of
    endangering behavior, harassment/physical assault, and breach of
    - 13 -
    expulsion as the appropriate sanction.            Haidak appealed to the
    University Appeals Board, which recommended that the sanction be
    upheld.     Enku   Gelaye,   the   Dean   of   Students   and   Acting   Vice
    Chancellor of Student Affairs, upheld the expulsion based on the
    Appeals Board's recommendation.
    Haidak then took the fight to federal court.           He filed
    a two-count complaint against the university and the officials
    involved. The first count alleged due process and equal protection
    violations, and the second count asserted a violation of Title IX,
    
    20 U.S.C. § 1681
    .     Both parties moved for summary judgment, and
    the district court allowed the university's motion and denied
    Haidak's.     Haidak, 299 F. Supp. 3d at 271.         Haidak appeals the
    dismissal of his procedural due process and Title IX claims to
    this court.
    university policies. The university ultimately dropped the more
    serious charges when Haidak agreed to be found responsible for
    violating university policies. Haidak received the sanctions of
    housing probation, anger management meetings, and alcohol
    education workshops.
    In 2012, the Amherst Police Department arrested Haidak and
    charged him with nuisance, noisy and disorderly house, and
    disturbing the peace.    The university charged Haidak with CSC
    violations of alcohol, endangering behavior, and violations of
    local, state, or federal law.    When Haidak agreed to be found
    responsible for violating local, state, or federal law, the
    university dropped the other two charges.    Haidak received the
    sanctions of a reprimand and the writing of a three-page paper on
    alcohol and student disturbances. Vaillancourt was "disheartened"
    by Haidak's reflection paper, which said that "[k]ids will party
    no matter what.     End of story . . . .    Is this responsible?
    Certainly not, but it is a simple truth."
    - 14 -
    II.
    We turn first to Haidak's appeal from the district
    court's dismissal of his procedural due process challenges to his
    suspension and expulsion.         We review de novo a district court's
    decision on summary judgment, "drawing all reasonable [factual]
    inferences in favor of the non-moving party."          Doe v. Trs. of Bos.
    Coll., 
    892 F.3d 67
    , 79 (1st Cir. 2018) (quoting Roman Catholic
    Bishop of Springfield v. City of Springfield, 
    724 F.3d 78
    , 89 (1st
    Cir. 2013)).    Summary judgment is appropriate only when "there is
    no genuine dispute as to any material fact and the movant is
    entitled to judgment as a matter of law."           Fed. R. Civ. P. 56(a).
    It has long been clear that, though states have broad
    authority to establish and enforce codes of conduct in their
    educational    institutions,      they     must   "recognize   a   student's
    legitimate entitlement to a public education as a property interest
    which is protected by the Due Process Clause and which may not be
    taken   away   for   misconduct    without    adherence   to   the   minimum
    procedures required by that Clause."         Goss v. Lopez, 
    419 U.S. 565
    ,
    574 (1975); see also Gorman v. Univ. of R.I., 
    837 F.2d 7
    , 12 (1st
    Cir. 1988) ("[A] student facing expulsion or suspension from a
    public educational institution is entitled to the protections of
    due process.").
    "Once it is determined that due process applies, the
    question remains what process is due."            Morrissey v. Brewer, 408
    - 15 -
    U.S.    471,    481   (1972).        To   determine     what    process    is
    constitutionally due, we generally balance three factors:
    First, the private interest that will be
    affected by the official action; second, the
    risk of an erroneous deprivation of such
    interest through the procedures used, and the
    probable value, if any, of additional or
    substitute    procedural   safeguards;    and
    finally, the Government's interest, including
    the function involved and the fiscal and
    administrative burdens that the additional or
    substitute   procedural   requirement   would
    entail.
    Mathews v. Eldridge, 
    424 U.S. 319
    , 335 (1976); see also Gorman,
    
    837 F.2d at
    12–16 (applying the Mathews test to determine whether
    a university's disciplinary proceedings afforded due process).
    The principal private and governmental interests at
    stake   in   school   disciplinary    proceedings     are   reasonably    well
    acknowledged.    Students have "paramount" interests "in completing
    their education, as well as avoiding unfair or mistaken exclusion
    from the educational environment, and the accompanying stigma."
    Gorman, 
    837 F.2d at 14
    .         The state university, in turn, has an
    important interest in protecting itself and other students from
    those whose behavior violates the basic values of the school, Goss,
    
    419 U.S. at 580, 583
    , and in balancing the need for fair discipline
    against the need to allocate resources toward "promot[ing] and
    protect[ing] the primary function of institutions that exist to

    837 F.2d at 14
    .            In theory, both
    parties also share an interest in speed and accuracy in the
    - 16 -
    adjudication of charges.         In this case, all of these interests
    were   implicated.      Haidak      faced   a   substantial    suspension      and
    complete expulsion, while the university had probable cause to
    believe that he had used undue physical force on another student
    and continued to harass her.
    "Notice   and     an     opportunity       to    be    heard     have
    traditionally and consistently been held to be the essential
    requisites of procedural due process."            
    Id. at 12
    .       In the school
    disciplinary context, the opportunity to be heard requires "some
    kind of hearing."      Goss, 
    419 U.S. at 579
     (emphasis added).              Here,
    we consider the adequacy of two hearings: one in connection with
    Haidak's suspension and the other in connection with his expulsion.
    We address each in turn, beginning with the expulsion hearing.
    A.
    The   expulsion   hearing      proceeded    in   accordance      with
    written procedures given to Haidak in advance.                 The hearing was
    limited to charges of which Haidak received timely and detailed
    notice.   Haidak makes no claim that any of the adjudicators was
    unfit for the job or should have been excluded for cause.                   Haidak
    was afforded the rights to be present at the hearing, to hear all
    evidence against him, to respond directly himself, and to call
    witnesses.    He was also allowed to have an attorney present and to
    consult with that attorney.         The burden of proof was placed on the
    - 17 -
    charging party to a degree unchallenged by Haidak.                         The hearing
    was recorded.
    Haidak     claims      that    the       hearing     was   nevertheless
    constitutionally flawed for two reasons: (1) some of his proffered
    evidence was excluded; and (2) he was not allowed to cross-examine
    Gibney.       In assessing these claims, we do not ask whether "the
    hearing mirrored a common law criminal trial," but simply whether
    Haidak       "had   an   opportunity     to       answer,   explain,      and   defend."
    Gorman, 
    837 F.2d at 14
    .
    1.
    Haidak argues first that the university unreasonably
    impeded his opportunity to defend against the charges by excluding
    certain        evidence        from    the        Hearing     Board       proceedings.
    Specifically, Haidak challenges the university's refusal to allow
    him to present: (1) a transcript of the state-court restraining
    order       hearing;7    and   (2) evidence        of    Gibney's    "propensity    for
    violence," consisting of a photograph of the bite mark Gibney left
    on Haidak's arm in February 2013 and the testimony of Haidak's
    mother about Gibney's history of physical aggression.
    7
    Cardoso maintains that, after she pointed out that the
    transcript included information that would be damaging to Haidak,
    and that Gibney would admit that some of their contact was
    consensual, Haidak chose not to put the transcript before the
    Board.   Haidak disputes this account, and for purposes of this
    appeal, we are required to credit Haidak's version of the facts.
    - 18 -
    The excluded transcript revealed that, in state court,
    Gibney first tried to minimize the extent of her welcomed contact
    with Haidak that took place after the no-contact orders were
    issued.   When pressed, she admitted to additional consensual
    interactions with Haidak.     Had Gibney thereafter successfully
    convinced the Hearing Board that there was no significant, post-
    order consensual contact between the two of them, one might well
    question the exclusion of the transcript. Gibney, though, admitted
    to the Hearing Board the consensual nature of her post-order
    contact with Haidak.    And as the district court aptly noted, the
    board acquitted Haidak of the harassment charge.    Haidak, 299 F.
    Supp. 3d at 266.       So, Haidak is reduced to arguing that he
    nevertheless should have been able to use the transcript to show
    that, because Gibney tried to mislead the state court on what
    transpired over the summer, she was also trying to mislead the
    Hearing Board on what transpired in Barcelona.
    As we noted earlier, the rules that govern a common law
    trial need not govern a university disciplinary proceeding.    See
    Gorman, 
    837 F.2d at 14
    .     But the rules of trial may serve as a
    useful benchmark to guide our analysis.    For example, even in a
    full-blown federal trial, "extrinsic evidence is not admissible to
    prove specific instances of a witness's conduct in order to attack
    or support the witness's character for truthfulness."     Fed. R.
    Evid. 608(b).   And extrinsic evidence aside, the court has ample
    - 19 -
    discretion     to    exclude    evidence   "if   its   probative   value   is
    substantially outweighed by a danger of . . . undue delay, wasting
    time, or needlessly presenting cumulative evidence."                Fed. R.
    Evid. 403.     Because a federal district court would have been well
    within its discretion in excluding the transcript, it follows a
    fortiori that an identical decision by the Hearing Board did not
    violate Haidak's right to due process.
    Similar reasoning applies to the exclusion of "evidence
    of [Gibney's] propensity for violence," including the photograph
    of the bite mark and the testimony by Haidak's mother.             Even in a
    federal criminal trial, "[e]vidence of a person's character or
    character trait is not admissible to prove that on a particular
    occasion the person acted in accordance with the character or
    trait."   Fed. R. Evid. 404(a)(1).           An exception to this general
    rule allows a defendant in a criminal case to "offer evidence of
    an   alleged        victim's   pertinent     trait,"   such   as    physical
    aggressiveness.       Fed. R. Evid. 404(a)(2).     However, such evidence
    may only be introduced in the form of testimony about the alleged
    victim's reputation or by testimony in the form of an opinion.
    Fed. R. Evid. 405(a).          Testimony by Haidak's mother that Gibney
    had previously struck Haidak would have exceeded this narrow
    exception.     And in any event, the evidence was redundant.         Haidak
    testified -- and Gibney did not dispute -- that "a lot of these
    instances occurred, these sort of instances where she would become
    - 20 -
    violent when she was drunk."             There was nothing unfair -- much
    less constitutionally unfair -- about the Board's decision to keep
    its focus on the events at issue.
    2.
    Next, Haidak argues that the Hearing Board violated his
    right to procedural due process by failing to accord him the
    opportunity    to   interrogate        Gibney      directly.       In    Gorman     v.
    University     of     Rhode     Island,        a    student      challenged         the
    constitutionality      of   university        disciplinary       proceedings    that
    resulted in his suspension.            
    837 F.2d at 9
    .       Among other things,
    Gorman    contended     that     the     university        deprived      him   of    a
    constitutional right to cross-examine members of the university
    Hearing Board on his allegations of bias.             
    Id. at 16
    .        We concluded
    that the University of Rhode Island did not violate Gorman's
    procedural due process rights, noting that "the right to unlimited
    cross-examination has not been deemed an essential requirement of
    due process in school disciplinary cases."                 
    Id.
     (emphasis added).
    Haidak urges us to hold that, while unlimited cross-examination
    may not be required, due process demands that the accused be
    allowed   to   question       opposing    witnesses        directly     whenever     a
    university     disciplinary      proceeding        turns    on    the    witnesses'
    credibility.
    In adjudicating Haidak's case, the university employed
    a non-adversarial model of truth seeking.              It was the university's
    - 21 -
    responsibility, rather than the parties', to investigate the facts
    and     develop     the    arguments     for    and    against     a   finding      of
    responsibility.       Neither party made opening or closing arguments
    to the board.       Though both parties submitted written statements of
    fact, neither submitted brief-like materials that argued for or
    against a finding of responsibility.                  Neither party questioned
    witnesses.
    Such a system of adjudication can fairly be called
    inquisitorial.       See Inquisitorial System, Black's Law Dictionary
    (11th ed. 2019) (defining "inquisitorial system" as a "system of
    proof-taking used in civil law, whereby the judge conducts the
    trial, determines what questions to ask, and defines the scope and
    the extent of the inquiry").            No doubt, this model of justice is
    not the one our founders chose for criminal trials.                     U.S. Const.
    amend. VI       ("In all criminal prosecutions, the accused shall enjoy
    the right . . . to be confronted with the witnesses against him
    . . . ."); see also Crawford v. Washington, 
    541 U.S. 36
    , 61 (2004)
    (The    Confrontation        Clause    "commands,      not    that     evidence     be
    reliable, but that reliability be assessed in a particular manner:
    by testing in the crucible of cross-examination.").                    But this is
    not    to   say   that     the    inquisitorial   model      is   constitutionally
    inadequate in all settings. In fact, we consider the inquisitorial
    model    fair     enough    for    critical    administrative      decisions      like
    whether to award or terminate disability benefits.                     See Sims v.
    - 22 -
    Apfel, 
    530 U.S. 103
    , 110–11 (2000) (explaining that Social Security
    proceedings are inquisitorial rather than adversarial).
    We are aware of no data proving which form of inquiry
    produces the more accurate result in the school disciplinary
    setting.     Considerable anecdotal experience suggests that cross-
    examination in the hands of an experienced trial lawyer is an
    effective tool.    See California v. Green, 
    399 U.S. 149
    , 158 (1970)
    (noting that cross-examination is "the greatest legal engine ever
    invented for the discovery of truth" (internal quotation marks
    omitted)).    One must keep in mind, however, that courts generally
    find that an accused student has no right to legal counsel in
    school disciplinary proceedings.    See Gorman 
    837 F.2d at 16
    .   Nor
    does Haidak assert such a right in this case.      So, his position
    would seem to be that the accused student must be allowed to
    question opposing witnesses himself.
    As a general rule, we disagree, primarily because we
    doubt that student-conducted cross-examination would so increase
    the probative value of hearings and decrease the "risk of erroneous
    deprivation," Mathews, 
    424 U.S. at 335
    , that it is constitutionally
    required in this setting.    In the hands of a relative tyro, cross-
    examination can devolve into more of a debate.        And when the
    questioner and witness are the accused and the accuser, schools
    may reasonably fear that student-conducted cross-examination will
    lead to displays of acrimony or worse.
    - 23 -
    This   is   not    to   say   that   a   university     can    fairly
    adjudicate a serious disciplinary charge without any mechanism for
    confronting the complaining witness and probing his or her account.
    Rather, we are simply not convinced that the person doing the
    confronting   must     be    the   accused   student   or   that    student's
    representative.      In this respect, we agree with a position taken
    by the Foundation for Individual Rights in Education, as amicus in
    support of the appellant -- that due process in the university
    disciplinary setting requires "some opportunity for real-time
    cross-examination, even if only through a hearing panel."
    Arguing that due process requires more than inquisition
    of the complaining witness by the factfinder alone, Haidak points
    to the Sixth Circuit's decision in Doe v. Baum, 
    903 F.3d 575
     (6th
    Cir. 2018).   In that case, a female student alleged that a male
    student had sex with her while she was so drunk that she could not
    consent.   Id. at 579.       The accused claimed that his accuser did
    not appear drunk and in fact expressly consented.            Id.     A school
    investigator found the competing versions in equipoise.                   Id. at
    580.   A university board then ruled against the accused student,
    with no testimonial hearing at all, because "Roe's description of
    events was 'more credible' than Doe's, and Roe's witnesses were
    more persuasive."      Id.    In a holding that we could easily join,
    the court found the complete absence of any examination before the
    factfinder to be procedurally deficient.             Id. at 581.         But the
    - 24 -
    court took the conclusion one step further than we care to go,
    announcing a categorical rule that the state school had to provide
    for cross-examination by the accused or his representative in all
    cases turning on credibility determinations.                       Id.
    We stop short of adopting that latter pronouncement
    because      we    have    no   reason   to    believe      that    questioning    of   a
    complaining witness by a neutral party is so fundamentally flawed
    as    to   create     a    categorically       unacceptable        risk   of   erroneous
    deprivation.        We also take seriously the admonition that student
    disciplinary proceedings need not mirror common law trials.                           See
    Goss, 
    419 U.S. at 583
     ("To impose . . . even truncated trial-type
    procedures might well overwhelm administrative facilities in many
    places and, by diverting resources, cost more than it would save
    in educational effectiveness."); Gorman, 
    837 F.2d at 16
     ("A major
    purpose of the administrative process, and the administrative
    hearing,      is     to     avoid     the     formalistic         adversary    mode     of
    procedure.").         If we were to insist on a right to party-conducted
    cross-examination, it would be a short slide to insist on the
    participation of counsel able to conduct such examination, and at
    that point the mandated mimicry of a jury-waived trial would be
    near complete.
    That still leaves us with the question of whether, in
    this case, the university's inquisitorial approach to ferreting
    out    the    truth       was   so   inadequate      that    it     violated   Haidak's
    - 25 -
    procedural due process rights.      When a school reserves to itself
    the right to examine the witnesses, it also assumes for itself the
    responsibility to conduct reasonably adequate questioning.                 A
    school cannot both tell the student to forgo direct inquiry and
    then fail to reasonably probe the testimony tendered against that
    student.
    Whether   the   university   in    this   case    fulfilled   that
    responsibility is a close question.          The university's manual for
    its Hearing Board implied that the Board should choose student
    comfort at the expense of serious examination.          It called for the
    Board to start by calming the student with "easy" questions, to
    avoid leading questions, and to beware of the "danger of pursuing
    a line of questions" because "it can be very adversarial." Efforts
    of this type to put a witness "at ease," when applied only to a
    complaining   witness,     helped   render     potentially      unfair   the
    proceedings in another recent case we decided.              See Trs. of Bos.
    Coll., 892 F.3d at 87.     Here, though, at least the manual advised
    the Board to use this ill-suited kid-gloves approach for witnesses
    on both sides of the dispute.
    Even more concerning, when Haidak proposed a list of
    thirty-six questions that he wanted the Board to ask Gibney,
    Cardoso struck twenty questions from the list before submitting it
    to the Hearing Board, thereby preventing the Board from knowing
    Haidak's proposed questions and deciding whether to ask them as it
    - 26 -
    saw the testimony play out. In this manner, the university created
    the possibility that nobody would effectively confront Gibney's
    accusations.
    As it turned out, the members of the Board nevertheless
    managed to avoid the pitfalls created by the university. The Board
    questioned Gibney at length on the matters central to the charges.
    It probed for detail8 and required her to clarify ambiguities in
    her responses.9     It inquired into her level of intoxication, asking
    for an estimate of the number of drinks she had consumed and if it
    was true that she had fallen down earlier in the night.                    By
    alternating between questioning Haidak and Gibney, ultimately
    examining each student three times, it engaged in an iterative
    process in which its questioning of Gibney was informed in real
    time by Haidak's testimony as the proceedings unfolded.              In so
    doing,   it    extracted   Gibney's   admission   that   she   continued   a
    8 For example, observing that Gibney's description of the
    incident "went a little fast," the Board asked, "Would you mind
    restating . . . how you got from the main room where you were
    arguing to the bedroom? Did you go there of your own accord? Were
    you pushed or pulled? You said he took you by the neck to there,
    but could you be more specific?".
    9 For example, a Board member asked whether Gibney and Haidak
    "[had] any contact that could be considered like a romantic
    relationship as a continuation from [their] prior relationship
    during the time when the no contact order was in place." When
    Gibney answered with a simple "yes," the Board member asked her to
    "explain what you mean by yes."       In response, Gibney stated,
    "[w]hen he came to Amherst we did have romantic, physical contact."
    - 27 -
    "romantic" relationship with Haidak after Barcelona and during the
    period covered by the no-contact orders.
    In arguing that the Board's questioning of Gibney was
    nevertheless constitutionally inadequate, Haidak points to four
    areas of inquiry that he claims the Board improperly failed to
    pursue.   For two of these -- Gibney's "propensity for violence"
    and her "untruthfulness at the restraining order proceeding" -- we
    rest on our discussion above.      As to the third area of inquiry,
    "the   post-Barcelona    steps    [Gibney]   took   to   conceal   her
    relationship with Haidak from her parents" and "whether [Gibney]
    lied to her friends about resuming contact with Haidak," we fail
    to see much, if any, probative value in such inquiries.        Gibney
    conceded that she and Haidak had consensual contact, including
    physical contact, while the no-contact orders were in place.       The
    Board also absolved Haidak of the harassment charge, and Gibney's
    desire to hide the ongoing relationship from her parents and
    friends seems irrelevant to whether Haidak's use of force was
    justified.    Finally, Haidak takes issue with the Board's decision
    not to inquire into whether Gibney "blamed her parents for the
    disciplinary proceedings" or "expressed a desire that all charges
    be 'dropped.'"    But it is unclear what relevance Gibney's feelings
    about the disciplinary process have to whether Haidak's use of
    force in Barcelona was disproportionate.
    - 28 -
    The Board's ultimate findings also reflect that its
    probing exposed weaknesses in the charges against Haidak.      The
    Board decided that Haidak was not responsible for Endangering
    Behavior, the most serious charge he faced, because "his actions
    did not rise to a level violating this policy." It similarly found
    him not responsible for either harassment charge because "the
    contact after the April incident was mutual and non-threatening."
    It found Haidak responsible for violating the no-contact orders,
    which he admitted, and assault, but only because "his behavior was
    disproportionate to the actions he attributed" to Gibney.     This
    finding seems reasonable, and was very likely the product of a
    judgment about the credibility of the two protagonists, the bruises
    on Gibney's wrists, and the undisputed fact that she immediately
    reported to her mother that Haidak had assaulted her.    Moreover,
    Gibney testified in person, while Haidak chose to appear by phone,
    a decision that possibly created a greater disadvantage than that
    posed by any of the challenged procedures.
    All in all, the Board managed to conduct a hearing
    reasonably calculated to get to the truth by allowing Haidak to be
    heard after Gibney testified and by examining Gibney in a manner
    reasonably calculated to expose any relevant flaws in her claims.
    We therefore disagree with Haidak that the expulsion hearing did
    not provide due process.
    - 29 -
    B.
    We    turn    next    to    the    process     surrounding        Haidak's
    suspension pending the expulsion hearing.                  To recap, on June 3
    and 4, Gibney and her mother presented Berger with evidence that
    Haidak    had    called   Gibney       thirty-one   times       after      the   May 28
    no-contact order was issued.               Thirteen days later, and without
    prior notice, Berger suspended Haidak indefinitely. Two days after
    that, Berger spoke on the phone with Haidak and his father and
    agreed to review Haidak's written response to the charges.                          As
    best the record reflects, Berger did not thereafter confront Gibney
    with   those     responses,      instead      letting    the    suspension       stand.
    Because the university failed to schedule an expulsion hearing
    before November, the suspension lasted five months.
    While it lasts, a suspension more or less deprives a
    student of all the benefits of being enrolled at a university.
    The Supreme Court has held that a deprivation of this sort requires
    notice and a hearing.            See Goss 
    419 U.S. at 579
     ("At the very
    minimum   . . .     students      facing      suspension       and   the    consequent
    interference with a protected property interest must be given some
    kind of notice and afforded some kind of hearing.").                       What type of
    notice and what type of hearing turn on the interests implicated
    in each particular case.          See Doe v. Univ. of Cincinnati, 
    872 F.3d 393
    , 400 (6th Cir. 2017) ("The more serious the deprivation, the
    more demanding the process.").
    - 30 -
    As a general rule, both notice and a hearing should
    precede a suspension.      Goss, 
    419 U.S. at 582
    ; Gorman, 
    837 F.2d at 12-13
    .    On occasion, though, exigencies may properly provide an
    exception to this general rule:       "Students whose presence poses a
    continuing danger to persons or property or an ongoing threat of
    disrupting the academic process may be immediately removed from
    school.     In such cases, the necessary notice and rudimentary
    hearing should follow as soon as practicable . . . ."           Goss, 
    419 U.S. at
    582–83; see also Elena v. Mun. of San Juan, 
    677 F.3d 1
    , 9
    (1st Cir. 2012) ("Although prior notice is generally required for
    a governmental deprivation of property to comport with procedural
    due process, the Supreme Court has held that there is an exception
    for cases 'where a State must act quickly, or where it would be
    impractical to provide predeprivation process.'" (quoting Gilbert
    v. Homar, 
    520 U.S. 924
    , 930 (1997))).
    Here, however, the record belies any claim of exigency.
    The university waited thirteen days after learning about the
    continued   contact   to   issue    the   suspension   order.    And   the
    university offers no evidence suggesting that it was infeasible to
    provide some type of process during the available thirteen days
    before it imposed a suspension.
    The university did allow Haidak to respond to the charges
    both orally and in writing fifteen days after Gibney complained
    and two days after the suspension took effect.         Given the apparent
    - 31 -
    absence of any perceived exigency, that process came too late to
    serve as an opportunity to be heard before the suspension began.
    And it was, in any event, insufficient to provide, by itself, due
    process in connection with a five-month suspension that ran through
    most of a semester.      Importantly, the university knew that on the
    key issue justifying a lengthy suspension -- whether the continued
    communication represented a threat to the university community --
    Haidak directly disputed Gibney's account in a manner that could
    be verified.    The university could easily have confronted Gibney
    with the information provided by Haidak, and even a rudimentary
    hearing would have revealed that Haidak's contact with Gibney was
    welcomed and reciprocated.      When a state university faces no real
    exigency and certainly when it seeks to continue a suspension for
    a lengthy period, due process requires "something more than an
    informal    interview    with   an    administrative     authority       of   the
    college."   Gorman, 
    837 F.2d at 14
     (quoting Dixon v. Ala. State Bd.
    of Educ., 
    294 F.2d 150
    , 158 (5th Cir. 1961)).                 But "an informal
    interview" is all Haidak received.
    Certainly,   a   university       may   proceed    in   stages.     A
    university can first ask a student to respond to the charge.                  And
    if the response offers no plausible defense, then the need for
    further inquiry diminishes, much like the manner in which a guilty
    plea eliminates the need for further proceedings.                   But when the
    response leaves the matter turning on credibility, the interests
    - 32 -
    at stake are as substantial as those implicated by an extended
    suspension, and no perceived exigency exists, a university must do
    more than presume one version to be correct.
    The   university     does      argue    that,   given     Gibney's
    accusations and Haidak's response, it had no need to conduct a
    more robust hearing.      The university points to Haidak's admission
    that he had repeatedly contacted Gibney even after the no-contact
    orders took effect.       But, had university officials conducted a
    more substantial hearing before suspending Haidak, they would
    likely have discovered that they misunderstood the nature of the
    contact   between   him   and   Gibney.      And   as   university   counsel
    forthrightly conceded at oral argument, the record does not compel
    a finding that the university would have suspended Haidak had it
    known that the communications were welcomed and reciprocated by
    Gibney. After all, the Board ultimately concluded that the contact
    between Haidak and Gibney was "non-threatening," undermining the
    university's contention that the illicit contact was a threat that
    warranted immediate suspension.        In sum, the suspension decision
    was not a slam dunk, and there was ample time to provide prior
    notice and a meaningful opportunity to be heard. On such a record,
    the university violated Haidak's due process rights.
    It is true, as the university argues, that the failure
    to provide a pre-suspension hearing ultimately caused no actual
    injury, because the final penalty of expulsion was imposed in
    - 33 -
    accordance with due process.        But the Supreme Court has ruled that
    a violation of procedural due process rights, even in the absence
    of actual injury, justifies a finding in favor of the student and
    an award of nominal damages.         See Carey v. Piphus, 
    435 U.S. 247
    ,
    266 (1978); see also Farrar v. Hobby, 
    506 U.S. 103
    , 112 (1992)
    ("Carey obligates a court to award nominal damages when a plaintiff
    establishes the violation of his right to procedural due process
    but cannot prove actual injury."); Ford v. Bender, 
    768 F.3d 15
    , 24
    (1st    Cir.    2014)   ("The   merits    of   the   deprivation   itself   are
    immaterial to the procedural due process analysis.").10
    C.
    Haidak also tries to advance an argument that the delay
    in convening his expulsion hearing was itself a violation of due
    process.       To a large extent, this argument is simply the flipside
    of the argument that we have already accepted, i.e., that he should
    not have been suspended for so long without a hearing.                 Haidak
    also seems to suggest that the delay independently harmed him
    because the version of the university's hearing procedures in
    effect prior to the fall of 2013 allowed for student-conducted
    cross-examination.        But Haidak develops no argument that due
    process requires the application of whatever procedural rules were
    in effect at the time of the offense or charge, so we deem any
    10
    We need not consider prior to remand how the district court
    should handle a motion for fees should one be filed.
    - 34 -
    such argument waived.        See United States v. Zannino, 
    895 F.2d 1
    ,
    17 (1st Cir. 1990) ("[I]ssues adverted to in a perfunctory manner,
    unaccompanied    by   some   effort    at    developed   argumentation,   are
    deemed waived.").
    III.
    Finally, Haidak challenges the district court's summary
    judgment dismissal of his Title IX claim.                Title IX prohibits
    federally funded universities from discriminating against students
    on the basis of sex.     
    20 U.S.C. § 1681
    (a).        Below, Haidak pursued
    both "erroneous outcome" and "selective enforcement" theories of
    liability.     See Yusuf v. Vassar Coll., 
    35 F.3d 709
    , 715 (2d Cir.
    1994) (explaining that attacks against a university disciplinary
    proceeding on grounds of gender bias generally fall within these
    two categories).11     On appeal, Haidak presses only the selective
    enforcement theory.     To succeed on such a claim, Haidak must show
    that "the severity of the penalty and/or the decision to initiate
    the proceeding was affected by the student's gender."           
    Id. at 715
    .
    11 Both parties agree on the theories of liability outlined
    in Yusuf. We have, in the past, applied the Yusuf framework to
    Title IX challenges based on disciplinary proceedings, though we
    have held off on deciding whether, as in the Second Circuit, "the
    temporary presumption afforded to plaintiffs in employment
    discrimination cases under Title VII applies to sex discrimination
    plaintiffs under Title IX as well." Trs. of Bos. Coll., 892 F.3d
    at 90 n.13 (quoting Doe v. Columbia Univ., 
    831 F.3d 46
    , 56 (2d
    Cir. 2016)).
    - 35 -
    Haidak alleges that both the decision to initiate charges and the
    penalty imposed were affected by his sex.
    Haidak's claim that the decision to initiate charges was
    affected by his sex rests on the fact that the university filed
    charges against him when Gibney accused him of misconduct, yet
    filed no charges against her when he accused her of misconduct.
    But the two were not similarly situated as complainants.                  Gibney
    and her mother affirmatively contacted the university to report
    her charges and to seek relief.          A reasonable administrator would
    have construed that contact as a request to pursue the matter so
    as to be able to provide relief.         Haidak's accusations came second
    in time and arose only defensively.            And when expressly told that
    he could initiate a charge under the CSC, he demurred.
    As     the    university    concedes,    it    still   could     have
    initiated a charge against Gibney on its own initiative.               The CSC
    provided   that    the    university    could    file    appropriate   charges
    against a student "[a]t the request of any student, faculty or
    staff member or independently."          But we see no basis in the CSC or
    in the record for concluding that the university always had to
    initiate a charge even when the student declined an invitation to
    do so.
    More importantly, showing that the university had an
    "unwritten, race-to-the-dean's-office policy," as Haidak alleges,
    is not enough to support an inference of discrimination on the
    - 36 -
    basis of sex.     To make out a claim under Title IX, Haidak must
    show that "gender bias was a motivating factor" in the disciplinary
    process.   Trs. of Bos. Coll., 
    892 F.3d 67
    , 90 (1st Cir. 2018)
    (quoting Yusuf, 
    35 F.3d at 715
    ).     At most, Haidak has alleged that
    the university pursued Gibney's case instead of his because Gibney
    made the allegation first -- not because Haidak's sex influenced
    the university.
    We turn next to Haidak's argument that the testimony of
    his expert witness justifies a trial on his claim that he was
    penalized more severely on account of his sex.          Haidak's expert
    analyzed   university   data    regarding   assault   charges   occurring
    between 2010 and 2015.         The data set included the sex of the
    complaining and charged students, the charges, whether there was
    a finding of responsibility, and what sanction followed.          It did
    not include the students' disciplinary records or any information
    about the charged conduct, including whether injuries resulted.
    The data revealed that ninety-three male students and twenty-six
    female students were found responsible for assault, and of these,
    thirteen students were expelled, all of whom were male.
    We have never recognized a private right of action for
    disparate-impact discrimination under Title IX.        See Alexander v.
    Sandoval, 
    532 U.S. 275
    , 283 (2001) (holding that there is no
    private right of action for disparate-impact discrimination under
    the similarly worded Title VI); see also Cannon v. Univ. of
    - 37 -
    Chicago,   
    441 U.S. 677
    ,   694–95    (1979)   (noting   that   Congress
    patterned Title IX after Title VI and intended to create the same
    remedies under both statutes).          Haidak, though, correctly argues
    that proper evidence of a statistical disparity may generate an
    inference of intentional discrimination.          Cohen v. Brown Univ.,
    
    101 F.3d 155
    , 170–71 (1st Cir. 1996) ("Title IX, like other anti-
    discrimination schemes, permits an inference that a significant
    gender-based statistical disparity may indicate the existence of
    discrimination.").
    For a statistical disparity to support an inference of
    sex discrimination, the evidence must "tend to show that there was
    a causal connection between the outcome of [the] disciplinary
    proceedings and gender bias."      Trs. of Bos. Coll., 892 F.3d at 91.
    Here, although the data show that male students were more often
    accused of and more often expelled for assault, the data fail to
    address an array of alternative explanations.         These trends could
    reflect, for example, that male students on average had lengthier
    disciplinary histories or committed more serious assaults, or that
    assaults committed by women were reported less often, rather than
    that the university discriminated against male students.           Haidak's
    expert acknowledged these weaknesses, stating in his deposition,
    "I'm not saying that there is proof here of discrimination, or
    even bias in sort of a colloquial sense."
    - 38 -
    Haidak half-heartedly counters that the district court
    prevented him from obtaining the kind of detailed data that would
    have allowed his expert to draw more robust conclusions.                  But
    Haidak's brief presses no appeal to the discovery orders that
    limited the data available to his expert and instead asserts that
    "the statistical universe upon which [the expert] relied was
    complete and highly relevant."
    Even if the foregoing weaknesses might not preclude the
    use of the expert's analysis in a disparate-impact case -- an issue
    we   need   not   decide   --   its    relevance   in   proving   intentional
    discrimination is further undercut by the absence of any evidence
    that the person who selected Haidak's penalty, Vaillancourt, was
    also the person who selected the penalties in the assault cases
    examined by Haidak's expert.           Even if one could infer from the
    data that another decision maker issued higher penalties based on
    sex, that inference says little about whether the decision maker
    in this case brought to bear any bias on the basis of sex.
    The university also provided a convincing, sex-neutral
    explanation for the sanction of expulsion:
    Despite the [two] earlier attempts by the
    University to redirect [Haidak's] decision-
    making and behavior, he had not altered his
    behavior. Further, in light of his flagrant
    violation of the university's [two] no contact
    orders, it was clear he would not comply with
    any future directives from the university to
    ensure the safety of himself, [Gibney], or
    others.
    - 39 -
    In light of this highly plausible explanation, and the weakness of
    the statistical evidence, we agree with the district court that no
    reasonable jury could infer from the expert's report that the
    decision to expel Haidak was motivated by his sex in violation of
    Title IX.
    IV.
    The university argues that, should we find that the
    district court erred, in whole or in part, in granting its motion
    for summary judgment, we should dismiss the claims for monetary
    relief against the university officials as barred by sovereign
    immunity under the Eleventh Amendment.               Haidak concedes that
    sovereign immunity bars his claims for monetary damages against
    the university officials acting in their official capacities, but
    notes   that   he   also   sued   the   university    officials   in    their
    individual capacities.      The Eleventh Amendment does not bar suits
    for damages against state officials sued in their individual
    capacities, though such officials are usually protected by common
    law immunity.       See Hafer v. Melo, 
    502 U.S. 21
    , 26 (1991).               We
    therefore   affirm    on   alternate    grounds   the   dismissal      of   the
    section 1983 claims for damages, but only against the university
    employees acting in their official capacities.
    In the alternative, the university argues that -- even
    if sovereign immunity does not bar the claims against the officials
    - 40 -
    in their individual capacities -- the university officials are
    protected by qualified immunity.                 However, the university failed
    to invoke qualified immunity below, and this defense is therefore
    waived.     See Guzmán-Rivera v. Rivera-Cruz, 
    98 F.3d 664
    , 667 (1st
    Cir. 1996) ("Since immunity must be affirmatively pleaded, it
    follows that failure to do so can work a waiver of the defense."
    (quoting Kennedy v. City of Cleveland, 
    797 F.2d 297
    , 300 (6th Cir.
    1986))).
    V.
    For    the     foregoing    reasons,       we    affirm   the   district
    court's dismissal of Haidak's section 1983 claims challenging the
    constitutional adequacy of his expulsion hearing; we affirm on
    alternate     grounds       the   district         court's    dismissal     of   his
    section 1983      claims    for   money      damages    against   the    university
    officials acting in their official capacities; and we affirm the
    dismissal of his Title IX claim; but we vacate for the entry of
    nominal monetary damages the dismissal of Haidak's section 1983
    claims challenging the constitutionality of the manner in which
    the university suspended him for five months without prior notice
    or   an   adequate   hearing.          We    remand    for   further    proceedings
    consistent with this opinion.                No costs are awarded to either
    party.
