    T YM K O VIC H, Circuit Judge.
    This appeal is our second review of the constitutionality of fees assessed by
    the City of Albuquerque and its municipal union, Local 624, against employees
    who were not members of the union. The Supreme Court has held that employees
    who are not members of a union may be assessed a fair share of the costs of union
    expenses arising from the negotiation of collective bargaining agreements and
    other union activities that benefit all of the employees of a public sector
    employer. Lehnert v. Ferril Faculty Ass’n., 500 U .S. 507 (1991). In the first
    appeal of this case, we held that the City’s “fair share fee” assessed for union
    activities violated the Constitution. Finding the fee overcharged non-member
    employees because it billed them for activities of the union that did not benefit
    them, we remanded the case for a hearing to determine the amount of the
    overcharge and to refund any excess fees to non-union employees. Wessel v. City
    of Albuquerque, 
    299 F.3d 1186
     (10th Cir. 2002) (Wessel I)
    -2-
    On remand, the district court concluded that the City and union had failed
    to prove what portion of fair share fees were allocated for activities benefitting
    Local 624. As a remedy for the constitutional violation, the court ordered Local
    624 to refund all fees it collected from the non-member employees. In addition to
    this refund, the district court also ruled that the City was required to refund
    amounts it received from Local 624 under an indemnification provision we held
    void as against public policy in Wessel I.
    In this appeal, the City and Local 624 challenge both conclusions. W e
    agree with the district court that Local 624 failed to meet its burden of proof in
    showing what portion of the fair share fee benefitted the non-member employees.
    W e conclude, however, that the district court applied the wrong standard in
    ordering the City to refund amounts it received under the indemnification
    provision.
    Having jurisdiction under 
    28 U.S.C. § 1291
    , we AFFIRM in part, and
    remand for further proceedings.
    I. Background
    Union Representation. The American Federation of State, County, and
    M unicipal Employees (AFSC M E), is a labor union that represents municipal
    employees nationwide. AFSC M E provides numerous services to its local
    affiliates, including contract negotiation, and representation in grievance and
    -3-
    arbitration proceedings. AFSCM E also provides some funds to its affiliates to
    pay local expenses incurred in providing these services.
    Local 624 is the largest AFSC M E local affiliate in New M exico,
    representing municipal employees of the City of Albuquerque. The City, in turn,
    recognizes Local 624 as the exclusive representative of municipal employees for
    collective bargaining purposes. See Albuquerque, N.M ., Code ch. 3, art. 2. City
    employees may join AFSCM E by paying a fee, which is divided among the local,
    council, and national entities.
    Employees who do not wish to join the union are not required to do so. See
    Albuquerque, N.M . Code § 3-2-4(A) (“City employees . . . have the right to
    refuse to join and participate in the activities of employee organizations.”).
    Under federal law , however, if at least 50% of employees in the bargaining unit
    are union members, non-union members may be charged a fair share fee, which is
    their “proportionate share of the union’s costs of negotiating and administering
    the collective bargaining agreement and adjusting the grievances and disputes of
    bargaining unit employees.” Id.
    The First Appeal. In 2000, thirteen City employees w ho chose not to join
    Local 624 filed suit under 
    42 U.S.C. § 1983
     against the City, various City
    officials, Local 624 and AFSC M E. The non-member employees claimed the
    defendants violated their First Amendment rights by requiring them to pay
    disproportionately high fair share fees. Both parties moved for sum mary
    -4-
    judgment. The district court ruled that Local 624’s fair share notice was
    unlawful, but ruled in favor of the defendants on all other claims, including the
    constitutionality of the fair share fees.
    In 2002, we reversed the district court’s conclusion that the fair share fees
    were constitutional. Applying Supreme Court precedent, we concluded that at
    least some of the purposes for which the fees were collected could not be charged
    back to non-union members. Wessel I, 
    299 F.3d at 1196
    . In particular, we found
    the portion of the fees collected that went to AFSC M E’s national union “to serve
    as exclusive representative in other bargaining units . . . would not inure to the
    benefit of the members of the local organization and their collection violates the
    principles expressed [by the Supreme Court in Lehnert].” 
    Id.
     Consequently, the
    portion of the fair share fee collected for these purposes w as not chargeable to
    non-union employees. W e also concluded a provision in the collective bargaining
    agreement allowing the City to be indemnified by the Union for services, which
    were later determined to be unconstitutional, was void as against public policy.
    
    Id. at 1199
    . W e remanded to the district court to determine how much of the fair
    share fee, if any, could appropriately be charged to the plaintiffs. 
    Id. at 1196
    .
    Remand. On remand, the union defendants urged the district court to find
    that the entire fee was properly chargeable to non-members. The district court
    disagreed for two reasons. It first concluded that Wessel I had already determined
    at least some portion of the fair share fee had been charged for activities that did
    -5-
    not benefit Local 624. Second, the district court held that the defendants had
    “failed to satisfy their burden of proof with regard to any of the fair share fees
    collected from the [non-members]” because they did not show “what portion went
    to other locals and, conversely, . . . what portion went to expenses related to
    bargaining on behalf of Local 624.” Op. at 16. Since the union defendants had
    failed to establish what portion of the fair share fees were chargeable to non-
    union members, the district court refunded the entire fee to the plaintiffs.
    The district court also ordered the City to refund Local 624 payments made
    pursuant to the indemnification clause we found to be void in Wessel I.
    II. Analysis
    The union defendants and the City raise two issues on this appeal. First,
    they claim the district court wrongly concluded that the entire fair share fee was
    not properly chargeable to Local 624. Second, they argue that the district court
    should not have ordered the City to refund the payments for litigation expenses
    paid by Local 624 under the indemnification provision. W e address each
    argument in turn.
    A. Chargeability of the Fair Share Fee
    The union defendants’ primary argument is that the entire fair share fee was
    constitutionally permissible. In support of their argument, they presented
    testimony at the remand hearing that all of the services of AFSC M E, as an
    exclusive bargaining representative at the national level, are also available to
    -6-
    Local 624 on an as-needed basis. Accordingly, they claim the entire fair share fee
    is properly chargeable to non-member employees. The union defendants also
    argue that our decision in Wessel I did not preclude the district court from
    reconsidering whether expenses related to exclusive bargaining were in fact a
    chargeable benefit to Local 624.
    The district court rejected these arguments. The court concluded that
    Wessel I precluded relitigation of whether exclusive bargaining representation
    inured to the benefit of Local 624. The district court also found the union
    defendants had failed to meet their burden of showing what portion of the fair
    share fee was unconstitutional. Specifically, the district court found the union
    defendants (1) did not show that fair share fees were “spent only on activities that
    the union considered to be chargeable to non-members” [Op. at 11]; (2) collected
    funds for services that were not chargeable under Supreme Court precedent and
    our decision in Wessel I; and (3) charged for services provided at the national
    level too nebulous to benefit Local 624. The court further found the union
    defendants’ argument that they could not apportion expenses for exclusive
    representation “lack[ed] credibility” as they had detailed information apportioning
    other chargeable services. Id.
    1. Scope of W essel I.
    -7-
    The union defendants’ first argument is that Wessel I did not foreclose the
    possibility that the entire fair share fee was chargeable to the non-member
    employees. W e disagree.
    Our previous decision considered “w hether the fees collected in this case
    violated the . . . constitutional standard on extra-unit expenses” as articulated in
    Lehnert v. Ferril Faculty Assoc., 
    500 U.S. 507
     (1991). Wessel I, 
    299 F.3d at 1196
    . In Lehnert, the Supreme Court notes “[t]here must be some indication that
    the payment is for services that may ultimately inure to the benefit of the
    members of the local union by virtue of their membership in the parent
    organization.” 
    500 U.S. at 524
    . Applying and quoting Lehnert, we held “extra-
    unit expenses [are] not chargeable if they [are] ‘unrelated to an objecting
    employee’s unit.’” Wessel I, 
    299 F.3d at 1196
    . After reviewing the record, we
    found “some evidence in the record that a portion of the fees collected went to the
    national Union to ‘[serve] as exclusive representative in other bargaining units.’”
    
    Id.
     Rejecting the union defendants’ argument that the entire fee was
    constitutional, we held:
    Such fees would not inure to the benefit of the mem bers of the local
    organization and their collection violates the principles expressed in
    Lehnert. W e disagree with the district court’s conclusion that the
    U nion did not exceed the constitutional limitations on the types of
    expenses properly included in a fair share fee.
    
    Id.
     Consequently, we remanded the case to the district court “to hold a hearing to
    determine which fees are attributable to bargaining-related expenses in [Local
    -8-
    624] as distinguished from those which do not inure to the benefit of the local
    bargaining unit.” 
    Id.
    W e agree with the district court that Wessel I explicitly resolved the
    question of the chargeability of the entire fair share fee for sums collected for use
    by AFSC M E as exclusive bargaining representative for other local unions. The
    panel’s opinion in Wessel I was unambiguous. W e stated that collection of fees
    for this purpose “violates the principles expressed in Lehnert,” 
    299 F.3d at 1196
    ,
    and remanded for necessary fact-finding on the amount of the overcharge.
    Accordingly, the district court did not err in its understanding of the scope of
    Wessel I.
    2. Law of the Case
    The union defendants argued below that the law of the case doctrine should
    not preclude them from showing their fees for exclusive bargaining services w ere
    properly chargeable to Local 624. On appeal, they argue the testimony at the
    remand hearing demonstrates that the panel in Wessel I was wrong in its holding
    that a portion of the fee was not properly chargeable. Again, we disagree.
    Generally, “once a court decides an issue, the same issue may not be
    relitigated in subsequent proceedings in the same case.” Grigsby v. Barnhart, 
    294 F.3d 1215
    , 1218 (10th Cir. 2002). “Unlike res judicata, the [law of the case
    doctrine] is not an ‘inexorable command,’ but is to be applied with good sense.”
    United States v. M onsisvais, 
    946 F.2d 114
    , 117 (10th Cir. 1991) (quoting M ajor v.
    -9-
    Benton, 
    647 F.2d 110
    , 112 (10th Cir. 1981)). Accordingly, the doctrine is subject
    to three exceptions: “(1) when the evidence in a subsequent trial is substantially
    different; (2) w hen controlling authority has subsequently made a contrary
    decision of the law applicable to such issues; or (3) when the decision was clearly
    erroneous and would work a manifest injustice.” Grigsby, 
    294 F.3d at 1219, n.4
    .
    W e read “these exceptions narrowly, requiring district courts to apply the law of
    the case unless one of the exceptions specifically and unquestionably applies.”
    M onsisvais, 
    946 F.2d at 117
     (internal quotations omitted).
    Here, only the first exception might be applicable. Under this exception,
    “[c]ourts have generally permitted a modification of the law of the case when
    substantially different, new evidence has been introduced.” M ajor v. Benton, 
    647 F.2d 110
    , 112 (10th Cir. 1981). The exception does not apply, however, where
    “the additional evidence provided . . . at the supplemental hearing was evidence
    [the proponent] had in its possession, but failed to produce, at the time of the
    original hearing.” M onsisvais, 
    946 F.2d at 117
    .
    In Wessel I, the foundation for our holding was the conclusion that charges
    for AFSC M E’s service as exclusive bargaining representative for local unions
    other than Local 624 “would not inure to the benefit of the members of the local
    organization.” 
    299 F.3d at
    1196 (citing Aplt. App. at 51, 53, 154, 156). On
    remand, the union defendants sought to counter this conclusion. They offered
    testimony that the accounting description had no substantive significance and,
    -10-
    therefore, funds dedicated to these functions did benefit local unions. Essentially,
    AFSC M E argues here that its services as national exclusive bargaining
    representative for other local unions are available to Local 624— and therefore
    chargeable to non-members.
    This issue was addressed in Wessel I. In those proceedings, the non-
    member employees identified AFSC M E’s bargaining representative services as an
    example of a non-chargeable expense. They argued:
    The original and revised notices do not limit expenses chargeable to
    nonmembers to the costs of negotiating and administering the collective
    bargaining agreement with the City and adjusting the grievances and
    disputes of bargaining unit employees. Both expressly state that
    chargeable expenses include “[s]erving as exclusive representative in
    other bargaining units.”
    Wessel I, Aplt. App. at 209. In response, the union defendants contended:
    Local 624 admits that the original and revised notice calculated the
    chargeability percentage based on expenditures germane to collective
    bargaining included, where appropriate, expenditures related to “[s]erving
    as exclusive representative in other bargaining units.” Local 624 disputes
    any implication that such expenditures are not authorized . . . .
    Id. at 253.
    W e are not persuaded on the basis of this prior record that the union
    defendants on remand have presented substantially different evidence such that a
    departure from the law of the case is warranted. Grigsby, 
    294 F.3d at
    1219 n.4;
    M ajor, 
    647 F.2d at 112
    . Accordingly, the district court did not err on remand in
    relying on our decision in Wessel I.
    -11-
    Having said this, we note the district court did accept testimony regarding
    the union defendants’ treatment of exclusive bargaining expenses. The court
    concluded the evidence did not show such expenses w ere properly chargeable to
    non-union members under Lehnert. Even if the law of the case doctrine did not
    apply, we are bound by the district court’s factual findings in this regard. W e
    thus turn to the evidence produced on remand.
    3. Burden of Proof
    In a thorough written order, the district court concluded the union
    defendants had not satisfied their burden of showing that the fair share fees were
    collected to finance costs associated w ith “otherwise chargeable activities”
    consistent with our decision in Wessel I. W e agree for two reasons. First, the
    record demonstrates the union defendants failed to produce any evidence showing
    what portion of the fair share fee funded AFSC M E’s work as exclusive bargaining
    representative. Second, the union defendants’ witnesses failed to convince the
    district court that those funds used for exclusive representation were also
    available to Local 624 and therefore chargeable. Our review of the district
    court’s factual determinations is for clear error. Nieto v. Kapoor, 
    268 F.3d 1208
    ,
    1221 (10th Cir. 2001).
    The primary reason the district court found the entire fair share fee should
    be refunded was the union defendants’ inability (or unwillingness) to separate out
    the costs of serving as exclusive bargaining representative from their total
    -12-
    expenditures. Under Lehnert, “the union bears the burden of proving the
    proportion of chargeable expenses to total expenses.” 
    500 U.S. at 524
    .
    On remand, the union defendants’ witnesses conceded they could not
    “determine the cost of serving as exclusive bargaining representative in other
    bargaining units.” Aplt. App. at 219–20. Based on this testimony, the district
    court concluded the union defendants’ attempt to justify their inability to meet
    their burden “does not provide a defense for not meeting it.” Op. at 14. Because
    of the lack of evidence, “[t]he portion that relates to the union serving as the
    exclusive bargaining representative of locals other than Local 624 was not
    properly collected from non-members and must also be refunded.” O p. at 15. It
    was undisputed that some portion of the fair share fee went to fund AFSCM E’s
    work as exclusive bargaining representative. Since the union defendants did not
    identify the various components that made up the fees, and because they had the
    burden of proof, the court ordered them to refund the entire amount. W e agree
    with this conclusion.
    Even if we were tempted to depart from the law of the case and consider
    the union defendants’ testimony that exclusive bargaining expenses w ere properly
    chargeable, we would still affirm. The district court concluded that the union
    defendants’ testimony lacked credibility and specificity such that it could not
    credit the explanation of the union defendants’ interpretation of exclusive
    bargaining services. “W e give the district court’s determinations regarding the
    -13-
    credibility of witnesses great deference.” Dill v. City of Edmond, 
    155 F.3d 1193
    ,
    1211 n.9 (10th Cir. 1998).
    W e agree with the district court that the lack of explanation undermined the
    union defendants’ claims. First, the district court found that the union defendants
    had “not shown with any persuasiveness that the money in the common fund into
    which fees ostensibly chargeable to non-members were placed was spent only on
    activities that the union considered to be chargeable to non-members.” Op. at 11.
    Second, the court found that some of the fees pooled and presumably available to
    Local 624 “were collected in order to recoup expenses that were not chargeable to
    non-members in the first place. . . . [E]armarking the fees for a chargeable
    purpose does not purge their unconstitutional taint when the fees are collected to
    finance non-chargeable activities.” Id. at 12. Third, as discussed above, the
    district court discounted the explanatory testimony of the union defendants since
    it was not persuaded that the Union could not separately account for fees
    expended on exclusive bargaining representation. See Op. at 13–14. Finally, the
    district court was troubled by the fact that the Union created a category of
    chargeable expenses it could neither explain in detail nor quantify.
    Did the union simply make up the amount of the fair share fee?
    Did it guess as to what the amount of the fee should be? The union
    was readily able to identify its chargeable activities when it billed
    non-members for them. It seems particularly convenient that it is
    suddenly unable to identify which of the fees are those the Court of
    Appeals held were improperly collected.
    -14-
    Op. at 14.
    In sum, the district court concluded it was “the union’s burden to show that
    the fair share fees were collected to finance ‘cost[s] associated w ith otherwise
    chargeable activities.’ Lehnert, 
    500 U.S. at 524
    . This it has not done.” Op. at 15.
    W hile we might have drawn different inferences from this evidence, we cannot
    conclude the district court clearly erred in finding the union defendants had not
    met their burden of proof. 1
    B. Indem nification and R estitution
    In a separate ruling, the district court ordered the City to return payments it
    received under the indemnification provision found unlawful in Wessel I. Both
    the union defendants and the City challenge the propriety of restitution since the
    district court never made a finding that the City’s policies violated the First
    Amendment. Before we address the merits of this claim, we must first clarify
    what is and is not at stake here.
    1
    The district court articulated another reason for concluding the union
    defendants evidence did not satisfy Lehnert: the fact that “union employees gain
    . . . experience . . . does not justify the union charging non-members for otherwise
    non-chargeable extra-unit activities.” Op. at 13. The court reasoned that this
    expertise would not “ultimately inure to the benefit of the members of the local
    union,” as required by Lehnert. See 
    500 U.S. at 524
    .
    W e disagree— such expertise could inure to Local 624’s benefit at some
    later date, even if it does not do so “in any particular membership year.” See 
    id.
    “The essence of the affiliation relationship is the notion that the parent will bring
    to bear its often considerable economic, political, and informational resources
    when the local is in need of them.” 
    Id. at 523
    .
    -15-
    In Wessel I, we held the indemnification agreement between the City and
    Local 624 was void as contrary to public policy because it would allow the City
    to seek indemnification “for its own unconstitutional practices and policies.” 
    299 F.3d at
    1199 n.4. In particular, the agreement required Local 624 to indemnify
    the City “against any and all claims, demands, suits or other forms of liability,
    including payments of reasonable attorney fees and costs . . . for any claim or
    challenge to the imposition of an agency fee.” 
    Id. at 1197
    . Pursuant to this
    provision, Local 624 had reimbursed the City for some of its legal expenses in
    this case. Relying on our holding in Wessel I, the district court ordered the City
    to return to Local 624 the indemnification it had received. [O p. at 22.] The court
    also enjoined the City from seeking future indemnification from Local 624 under
    this provision. [Id.]
    Neither the City nor Local 624 challenge the prospective injunction— they
    argue only that the court erred by ordering restitution of payments made to the
    C ity for the cost of litigation in these matters. Thus, this is not a case where w e
    are asked to prospectively “permit enforcement of those [voided] provisions,” as
    plaintiffs argue. Aple. Br. at 38. Rather, the only issue before us is whether
    restitution is required where one party has performed on a contract that was later
    voided as contrary to public policy. The non-union employees argue that
    restitution is also necessary here to prevent the City from benefitting from the
    voided contractual provision.
    -16-
    The parties agree the general rule is that restitution is not proper where one
    party has performed on a contract later voided for public policy reasons. See,
    e.g., Hogue v. Superior Utils., 
    210 P.2d 938
    , 940 (N.M . 1949); Restatement
    (Second) of Contracts § 197. Under this rule, the court “will simply leave both
    parties as it finds them, even though this may result in one of them retaining a
    benefit that he has received as a result of the transaction.” Id. § 197, cmt. a.
    This rule is subject to various exceptions. Hogue, 210 P.2d at 940 (stating
    that “where the public interest is involved . . . affirmative relief will not be
    denied, although one of the guilty parties may benefit”); Restatement (Second) of
    Contracts § 197 (authorizing restitution in all cases where “denial of restitution
    would cause disproportionate forfeiture”); id. § 198(b) (authorizing restitution
    where the party seeking restitution “was not equally in the wrong with the
    promisor”); id. § 199(b) (authorizing restitution where the claimant “did not
    engage in serious misconduct” and “allowance of the claim would put an end to a
    continuing situation that is contrary to public policy”).
    A more recent formulation of the exceptions identified in the Restatement
    (Second) of Contracts is found in the Restatement (Third) of Restitution,
    currently under consideration by the American Law Institute. 2 It points to
    restitution as appropriate in circumstances w here one party is unjustly enriched at

    In relation to the Restatement (Second) of Contracts, cited above, this
    section “reformulates the applicable rules without proposing to alter specific
    outcomes.” Restatement (Third) of Restitution § 32 cmt. a (T.D. No. 3, 2004).

    the expense of the other, even “under an agreement that is illegal or otherwise
    unenforceable for reasons of public policy.” § 32 (T.D. No. 3, 2004). 3 Another
    circumstance where restitution might be appropriate is where it will deter future
    misconduct. The draft Restatement suggests courts look to a variety of factors to
    assess the need for restitution, including (1) the nature of the illegality; (2) the
    extent of the party’s culpability; (3) w hether illegal conduct was central or merely
    tangential to the performance of the contract; and (4) the strength of the deterrent
    effect of the decision. Id.
    The question here then is whether restitution is necessary to (1) prevent
    unjust enrichment of the City, or (2) deter future misconduct by the City or other
    municipalities. The first factor does not appear to apply: the union defendants
    are not seeking reimbursement, rather the non-member employees are seeking
    disgorgement of the indemnification proceeds.

    It reads in full:
    (1) Restitution will be allow ed, whether or not necessary to prevent unjust
    enrichment, if restitution is required by the policy of the underlying
    prohibition.
    (2) Restitution will also be allow ed, as necessary to prevent unjust
    enrichment, if the allowance of restitution will not defeat or frustrate
    the policy of the underlying prohibition. There is no unjust
    enrichment if the claimant receives the counterperformance specified
    by the parties’ unenforceable agreement.
    (3) Restitution will be denied, notwithstanding the enrichment of the
    defendant at the claimant’s expense, if a claim under subsection (2)
    is foreclosed by the claimant’s inequitable conduct.

    The deterrence rationale might apply, however. That rationale may
    generally be appropriate in at least two circumstances in the context of
    unconstitutionally collected fair share fees. First, where the City knowingly
    participated or acquiesced in the unconstitutional conduct of the union
    defendants. Second, even if the City did not knowingly allow the violation,
    where it failed to exercise reasonable prudence to ensure the union defendants’
    fair share procedures w ere constitutional.
    Knowing Participation. The first consideration is w hether the City
    knowingly participated or acquiesced in the constitutional violation. In Wessel I,
    we declared the indemnification provision void on the ground that the City should
    not be indemnified “for its own unconstitutional practices and policies.” Wessel
    I, 
    299 F.3d at 1199
    . W e also held “[t]hat a public employer has certain
    obligations within the fair share deduction framew ork established by courts.” 
    Id. at 1197
    . These duties include a duty to establish procedures that protect
    dissenters’ rights, minimize impingement on non-union employees’ constitutional
    rights, and ensure that the union’s notice is adequate. See 
    id. at 1198
    .
    Furthermore, we stated that “[i]f the City consistently made no effort to ensure
    that the Union’s fair share procedures complied with [Chicago Teachers Union
    Local, No. 1 v. Hudson, 
    475 U.S. 292
     (1986)], such a failure would likely be
    cognizable under § 1983 and covered by the indemnification.” Id. at 1199 n.4.
    -19-
    Because the breadth of the indemnification clause would cover the types of
    violations described above, we found it contrary to public policy in Wessel I. W e
    did not conclude, however, that the City had violated the First A mendment in its
    implementation of its fair share policies. W e found only that the indemnification
    provision would allow payments for knowing violations of the constitutional
    notice requirements of Hudson, or conscious disregard of its basic fair share
    procedures. Thus, we did not conclude as a factual matter that the City had
    knowingly participated or acquiesced in the union defendants’ First Amendment
    violation. Nor did the district court make a finding on remand that the City
    violated the First Amendment.
    Reasonable Prudence. On this record, however, the district court
    concluded there is some support that the second consideration had been met— the
    City failed to exercise reasonable prudence in ensuring the union defendants’ fair
    share program satisfied constitutional standards. The district court found the non-
    member employees had “suffered irreparable injury . . . due to the City’s failure
    to fulfill its obligation to protect them.” Op. at 21. It concluded “inasmuch as
    the legally inadequate fair share notice and the collection of the fair share fees
    violated the Plaintiffs’ First Amendment rights, [] the City could not possibly
    have fulfilled its obligation to ‘provide procedures that minimize that
    impingement [on non-members’ First Amendment rights] and. . . facilitate a
    -20-
    nonunion employee’s ability to protect his rights.’” Op. at 20 n.5 (quoting
    Hudson, 
    475 U.S. at
    307 n.20).
    In reaching this conclusion on remand, the district court did not apply the
    legal framew ork discussed above. Its conclusions were made in the context of a
    motion for preliminary injunction that principally sought prospective relief. In
    light of our discussion of the applicable framew ork, it is now appropriate for the
    district court to make the equitable determination of restitution in the first
    instance. W e therefore remand for further proceedings on whether restitution
    should be ordered in light of the principles discussed above.
    III. Conclusion
    For these reasons, we REM AND for further proceedings on the issue of
    restitution and AFFIRM all other aspects of the district court’s decision.
