Baltimore County v. Fraternal Order of Police, Baltimore County Lodge No. 4
No. 25, September Term 2015




Civil Procedure - Law of the Case. Under the law of the case doctrine, a ruling by an
appellate court on a particular issue in a case is binding on the lower courts in future
proceedings in the same case. While the law of the case doctrine is subject to certain
exceptions, its application does not depend on the extent to which the appellate court
elaborates the reasons for its ruling. The doctrine applies not only to arguments presented
and resolved as part of the prior decision, but also arguments that could have been presented.

Public Employees - Collective Bargaining - Interest Arbitration and Grievance
Arbitration. The Baltimore County Charter authorizes collective bargaining between the
County and its employees. The Baltimore County Code provides for binding interest
arbitration to resolve an impasse in bargaining with certain public safety employees in order
to set the terms of the collective bargaining agreement with those employees. A particular
collective bargaining agreement may provide a grievance process to resolve various disputes
that may arise under an agreement, such as disputes about the application or interpretation
of the agreement; a grievance process under a collective bargaining agreement may include
binding grievance arbitration.

Public Employees - Collective Bargaining - Arbitration - Budgetary Administration.
Under the Baltimore County Code, when binding interest arbitration is invoked to resolve
an impasse in negotiations with public safety employees, the arbitration award sets the terms
of the collective bargaining agreement. However, the terms of the agreement for which
funding is required are effective and the arbitration award is enforceable only if the County
Council appropriates the required funds through the County’s budget process. By contrast,
when a grievance concerning the interpretation or application of an existing collective
bargaining agreement is resolved by a grievance arbitration award, the effectiveness of that
award does not necessarily depend on subsequent Council action.

         As authorized under local law, Petitioner Baltimore County engages in collective

bargaining with its employees. Respondent Fraternal Order of Police, Baltimore County

Lodge No. 4 (“FOP”) represents the County’s eligible police officers. The County and FOP

have entered into numerous collective bargaining agreements over the years. This case arose

out of a dispute over the interpretation of a provision in some of those agreements that

provided for a fixed subsidy of health insurance costs for officers who retired during certain

years.

         The dispute proceeded, in accordance with the grievance process in the collective

bargaining agreements, to binding arbitration. The FOP won the arbitration, but the County

sought to overturn the arbitration award in the courts. Among other things, the County

argued that the arbitration award was invalid because it was subject to the County’s executive

budget process. The Circuit Court for Baltimore County rejected the County’s various

challenges to the award – a decision ultimately upheld by this Court.

         When the case returned to the Circuit Court, the County balked at complying with the

arbitration award arguing that the award, even if valid, was unenforceable because it was

subject to the County’s executive budget process. That argument was indistinguishable from

one of the issues that the County had advanced on its prior trip up the appellate ladder and

that this Court had rejected on that occasion.

         The repetition of the issue from the prior appeal allowed the lower courts to dispose

of the issue under the law of the case doctrine. That doctrine expresses the principle, subject

to some exceptions, that a court presented with the same issue decided by an appellate court
at an earlier stage of the same case will rule the same way. It may have been with that

concept in mind that a noted philosopher in another line of work once said: “it’s like deja

vu all over again.” 1

       We hold that the lower courts properly applied the law of the case doctrine here. Even

if that doctrine did not control the outcome, the County would fare no better on the merits

of its argument.

                                        Background

       The underlying facts and procedural path of this case have been recounted well and

at length in two prior reported appellate decisions. See Fraternal Order of Police Lodge No.

4 v. Baltimore County, 429 Md. 533, 538-41, 57 A.3d 425 (2012); Baltimore County v.

Fraternal Order of Police Lodge No. 4, 220 Md. App. 596, 600-50, 104 A.3d 986 (2014).

There is no need to reprise them in the same detail here. We reiterate briefly the main points.

A.     Facts

       Collective Bargaining with County Employees

       In accordance with the Baltimore County Charter and the Baltimore County Code

(“BCC”), Baltimore County engages in collective bargaining with the exclusive

representatives of various categories of its employees.2        Among those categories of

       2
           Baltimore County Charter, §801; BCC §4-5-201 et seq.

                                              2
employees are police officers below a certain rank, who are represented by the FOP. The

negotiations result in an agreement that is called a “memorandum of understanding” or

“MOU.” Under the County Charter, disputes with the representatives of certain public safety

employees may be resolved through binding arbitration. Among the provisions that may

appear in an MOU are those pertaining to health insurance benefits, including health

insurance benefits for retirees.

       The OPEB Fund

       The County maintains a fund known as the Other Post-Employment Benefits Trust

Fund (“OPEB Fund”). The OPEB Fund is the repository of funds appropriated for payment

of health and life insurance benefits for County retirees and their beneficiaries. BCC §10-14-

103(a).   Each year, the County, through its budget process, appropriates an annual

contribution to the OPEB Fund. BCC §10-14-104(a). The annual contribution is based on

an estimate of future costs, based in part on an actuarial analysis of the County’s potential

liabilities for such costs. Id.

       The MOUs

       Two provisions that appear in the MOUs between the County and the FOP for the

fiscal years from 1996 through 2007 are particularly pertinent to this case. Those MOUs

provided that the County would furnish the same subsidy of health insurance benefits for

officers who retired between February 1, 1992 and June 30, 2007 as for current employees




                                              3
– during that time, a subsidy of 85 per cent of the cost of the premium.3 In addition, those

MOUs also provided that the percentage subsidy at the time of retirement of an officer would

remain in effect until the retiree (or the retiree’s beneficiary) reached age 65. In later

versions of the MOU during that period, the reference to age 65 was changed to eligibility

for Medicare.

       The MOUs also contained a grievance process for resolving disputes concerning the

application or interpretation of an MOU. Among other things, the grievance procedure

provided for the filing of a “class grievance” on behalf of similarly situated employees. The

grievance procedure also provided for binding grievance arbitration if the parties were unable

to resolve a dispute at an earlier stage of the grievance process.4

       The Dispute

       After the 2007 fiscal year, the County reduced the health insurance subsidy for current

employees.5 Despite the language in the earlier MOUs that the health insurance subsidy at

        The fiscal year 1996 MOU retroactively applied this provision to officers who had
retired between February 1, 1992 and July 1, 1995.
       4
         “Grievance arbitration” generally concerns the interpretation of an existing contract.
This is in contrast to “interest arbitration,” which generally concerns setting the terms of a
new contract after an impasse in negotiations. See Mayor and City Council of Baltimore v.
Baltimore City Firefighters Local 734, 136 Md. App. 512, 519-20 n.2, 766 A.2d 219 (2001);
Black’s Law Dictionary (9th ed. 2009) at 119-20.
       5
        Beginning July 1, 2007, the County began to reduce the proportion of an employee’s
health insurance premium paid by the County by one per cent per year until the County was
responsible for 80 per cent of the premium and the employee was responsible for 20 per cent
of the premium.

the time of retirement would remain in effect for a retiree until the retiree reached age 65 or

was eligible for Medicare, the County also reduced the health insurance subsidy for existing

retirees who had retired in years covered by those earlier MOUs.6

       Pursuant to the grievance procedure in the MOUs, in September 2007, the FOP filed

a class grievance on behalf of police officers who had retired during the period that the

MOUs included the provision that the health insurance subsidy at the time of retirement

would remain in effect until age 65 or eligibility for Medicare – i.e., those who retired

between February 1, 1992 and June 30, 2007. The County Labor Commissioner denied the

grievance on the ground that the provisions of the earlier MOUs were no longer controlling.

       The Arbitration Decision

       The grievance was not resolved at the initial steps of the grievance process. In

accordance with that process, the matter proceeded to binding arbitration.7 The arbitrator



       6
      The FOP concedes that officers who retired after the expiration of the fiscal year
2007 MOU are not entitled to the same subsidy as earlier retirees.
       7
        During the same time period, the FOP also sought to compel the County to engage
in further negotiations concerning the health benefits provisions that would be contained in
the fiscal year 2008 MOU and filed an unfair labor practice complaint against the County in
July 2007. In a separate arbitration, that issue was resolved in favor of the County. The
arbitrator in that case concluded that the County had negotiated in good faith with a
committee of union representatives that had been designated by the FOP as its bargaining
agent on health care issues for that MOU.

        The arbitrator who decided that case noted that the contractual grievance concerning
the entitlement of existing retirees to a health insurance subsidy under the earlier MOUs –
i.e., this case – was not before him. We agree that his decision does not bear on the
interpretation of the earlier MOUs that was the subject of the arbitration award in this case.

                                              5
concluded that the dispute was arbitrable and ruled in favor of the FOP on the merits of the

grievance. In a decision issued in July 2008, the arbitrator concluded that the “unequivocal

language” of the earlier MOUs – that “the health insurance subsidy in place at the time of

retirement shall remain in effect until the retiree reaches age 65 [or “becomes eligible for

Medicare”]” – was a binding promise that established a vested right for those retirees to

whom it applied. He ordered the County to rescind its modification of the retirees’ health

insurance subsidy, continue the previous subsidy in accordance with the MOUs, and

reimburse the retirees for the excessive deductions taken by County in the interim.

B.     Procedural History

       Affirmance of the Arbitration Decision in the Circuit Court

       In August 2008, the County filed an action in the Circuit Court for Baltimore County

to vacate the arbitration award, asserting numerous grounds.8 Among the grounds advanced

in that complaint, the County asserted that the award was “contrary to the very clear public


       8
         Among other things, the County has appeared to argue that its collective bargaining
agreements cannot confer a vested right to health care benefits for retirees. In a footnote in
its brief to us it cites an Attorney General opinion that discussed the extent to which State
legislation could alter a hypothetical contractual right of State retirees to health care benefits
without violating the Contract Clause in Article I, §10 of the federal Constitution. 90
Opinions of the Attorney General 195 (2005). That opinion concluded that any such
legislation would have to satisfy the standards articulated in Maryland State Teachers Ass’n
v. Hughes, 594 F.Supp. 1353 (D.Md. 1984), aff’d, No. 84-2213 (4th Cir. 1985), cert. denied,
475 U.S. 1140 (1986).

        That opinion is inapposite to this case. The County has not enacted legislation to alter
its contractual obligations, much less made a showing that such legislation would satisfy the
standards in Hughes.

                                                6
policy, as stated in the Baltimore County Charter and Code, that the Baltimore County

Council appropriates the funds needed to provide healthcare subsidies for retirees.”

       The Circuit Court, however, granted summary judgment in favor of the FOP and

declined to vacate the arbitration award. The court concluded that the dispute was arbitrable

despite the fact that the MOUs had expired prior to the filing of the grievance and that the

arbitrator had not committed a “manifest error” or exceeded his authority in deciding that the

retirees had a “vested right” to the maintenance of the health care subsidy for the period

provided in those MOUs. With respect to the County’s argument that the arbitration award

“usurped” the budget authority of the County Executive and County Council, the court noted

that, in this grievance arbitration, the arbitrator was simply interpreting an existing contract,

as opposed to setting the terms of a new contract, which might occur in interest arbitration

resulting from an impasse in negotiations.

       Reversal by the Court of Special Appeals Addressing One Issue

       The County appealed that decision, asserting that the Circuit Court had erred in

upholding the arbitrator’s award for nine reasons – essentially, the same arguments it made

before the Circuit Court. In particular, the County again asserted that the arbitration award

had “usurped” the budget powers of the County Executive and County Council. The Court

of Special Appeals, in an unreported decision, did not address any of the alleged errors,

including the County’s argument concerning its budget process, but reversed the arbitration

award on the ground that the Circuit Court had failed to consider whether the arbitration



                                               7
clause of the fiscal year 2007 MOU – as well as the health insurance benefits – had survived

the expiration of that MOU.

       Reversal by the Court of Appeals and Remand to Affirm the Circuit Court

       This Court granted the FOP’s petition for a writ of certiorari. The County did not file

a cross-petition. In its brief in that appeal, the County not only urged affirmance of the

decision of the Court of Special Appeals on the issue whether the arbitration clause had

expired but also listed the nine issues it had raised in its appeal and touched upon the merits

of the arbitrator’s decision.

       This Court reversed the decision of the Court of Special Appeals. 429 Md. 533, 57

A.3d 425 (2012). The Court held that the question of arbitrability was for the arbitrator to

decide in the first instance. The Court observed that the fiscal year 2007 MOU contained a

broad arbitration clause that was not necessarily abrogated by expiration of the MOU. 429

Md. at 555-56. The Court also held that the Circuit Court had applied the proper standard

of review of the arbitration award, and after reviewing the arbitrator’s findings, found no

reason to disturb the Circuit Court’s award of summary judgment in favor of the FOP on the

merits. Id. at 557-64. Although the Court stated that the arbitration award was consistent

with the MOU and agreed with the Circuit Court that it did not demonstrate a “manifest

disregard for the law,” the Court did not discuss in any detail the grounds that the County had

originally advanced for overturning the arbitration award and that the Circuit Court had




                                              8
rejected. In its mandate, the Court directed the Court of Special Appeals to affirm the

decision of the Circuit Court upholding the arbitration award. Id. at 565.

       The County sought reconsideration of this Court’s decision. In its memorandum in

support of that motion, the County argued, among other things, that instead of directing the

intermediate appellate court to affirm the Circuit Court, this Court should have directed the

Court of Special Appeals to address the various issues raised by the County but not discussed

in the prior decision of the intermediate appellate court. The County also asserted that the

award “will be unenforceable, since there have been no funds appropriated through the

executive budget process to afford the relief ....” This Court denied that motion on January

18, 2013.

       County Failure to Comply with Arbitration Decision

       One might think that the matter would be concluded upon return of the file to the

Circuit Court. To the contrary, it proved to be the starting point for another round of

litigation.

       The County refused to comply with the arbitration award. It did not rescind its

modification of the retired officers’ subsidy and reinstate the subsidy keyed to retirement

date. Nor did it refund to those retirees the excess deductions taken for health insurance

premiums during the fiscal years from 2008 through 2012.




                                             9
       Motion to Enforce Arbitration Award in Circuit Court

       The FOP promptly filed a motion to enforce the judgment in the Circuit Court. The

County opposed that motion. As grounds for its opposition, the County conceded that the

arbitrator’s award was valid but again asserted that it was unenforceable because the

enforcement of the award without an appropriation would “usurp” the authority of the

County Executive and the County Council under the County Charter. As a shorthand, we

will refer to the County’s contention in this regard as the “no-appropriation argument.”

       At a hearing on the motion and in subsequent filings, the County relied on the no-

appropriation argument for its assertion that the arbitrator’s award was unenforceable as a

matter of public policy. On August 14, 2013, the Circuit Court issued a memorandum and

order rejecting the County’s argument and granting the FOP’s motion to enforce the award.

In that memorandum, the court noted that the County had raised the no-appropriation

argument during the prior appeal and had spotlighted it in its motion for reconsideration

before this Court without success. The Circuit Court concluded that the law of the case

doctrine precluded the County from reprising the no-appropriation argument.

       The County filed a motion to alter or amend the judgment. In response to that motion,

the Circuit Court stayed part of its order, pending a damages hearing to determine the

amounts owed to the retired police officers with respect to the excessive deductions taken

during fiscal years 2008 through 2013.




                                            10
         Damages Hearing in Circuit Court

         At the damages hearing, the County once again asserted that there was no source of

appropriated funds from which it could comply with the Circuit Court’s order and reimburse

the retirees for the excessive health insurance premiums that the retirees had paid (but that

the County actually owed under the earlier MOUs pursuant to the arbitration award). The

County resisted providing information concerning the excess premiums paid by the retirees

during the period in question and attempted instead to re-argue the merits of the arbitration

award.

         In April 2014, the Circuit Court ordered the County to make refunds to the retirees in

amounts totaling more than $1.6 million, including pre-judgment and post-judgment interest.9

The County promptly noted an appeal, but apparently did nothing to satisfy the judgment,

which had not been stayed.

         Contempt Proceedings and Payment of Judgment from OPEB Fund

         While the County’s appeal to the Court of Special Appeals was pending, the FOP

initiated contempt proceedings in the Circuit Court for the County’s failure to satisfy the

judgment. In response, the County at first reiterated the no-appropriation argument and

asked the Circuit Court to quash the show cause order. Shortly after the Circuit Court denied




         9
         An initial judgment of more than $1.4 million was amended to include pre-judgment
interest.

                                               11
that motion, the County filed a certificate of compliance documenting that it had paid the

judgment and obviating the need for further contempt proceedings.10

       In a certificate of compliance that the County filed to document its compliance with

the court order, it advised that it paid the judgment with funds from the OPEB Fund allegedly

“without the required appropriation.” At oral argument in this appeal, the County conceded

that the OPEB Fund consisted of funds appropriated for retiree health insurance benefits.

       Appeal of the Circuit Court’s Enforcement Decision

       The Court of Special Appeals affirmed the Circuit Court in a comprehensive opinion.

220 Md. App. 596, 104 A.3d 986 (2014). In the course of that opinion, the court noted that

the Circuit Court had specifically addressed and rejected the County’s no-appropriation

argument prior to the first appeal in the case. 220 Md. App. at 617-19. The intermediate

appellate court observed that this Court had necessarily considered the no-appropriation

argument when we determined in the prior appeal that the Circuit Court had properly granted

summary judgment and also when we denied the County’s motion for reconsideration of that

decision. Accordingly, the intermediate appellate court reasoned, the law of the case doctrine




       10
         In total, the County certified that it expended a total of $1,696,403.98, including
$1,413,120.81 to satisfy the judgment, $213,446.47 to satisfy the pre-judgment interest,
$55,348.68 to satisfy the subsidy amounts for April and May 2014, and $14,488.02 in post-
judgment interest. As the FOP’s counsel acknowledged at oral argument, it is acting as an
agent for the retirees who paid more than their share of health benefits costs and has received
the funds relating to the health care subsidy as their agent.

                                              12
was fatal to this challenge. Id. at 656-62. The Court of Special Appeals also rejected

numerous other challenges raised by the County to enforcement of the arbitration award.11

       The County then filed a petition for a writ of certiorari, which we granted. In its

petition, the County focused on whether its no-appropriation argument supported a public

policy exception to enforcement of the arbitration award.12

                                              II

                                          Discussion

       As this Court recently reiterated, judicial review of an arbitration decision is “very

narrowly limited.” Prince George’s County Police Civilian Employees Ass’n v. Prince

George’s County, 447 Md. 180, 192, 135 A.3d 347 (2016) (interior quotation marks and

       11
          Citing the law of the case doctrine, the Court of Special Appeals also rejected four
other issues raised by the County that had been part of the prior appeal. 220 Md. App. at
650-62. In addition, the court addressed several other issues that arose in the Circuit Court
following the remand from the prior appeal and that necessarily had not been decided in the
prior appeal. Id. at 662-68. In particular, it declined to decide whether the Circuit Court’s
threat to incarcerate County officials as part of the contempt proceedings was
unconstitutional, as the issue had become moot. The court rejected arguments that the FOP
lacked standing to seek injunctive relief and damages on behalf of its members, that the
County should have been permitted to present testimony to effectively re-litigate the merits
of the grievance during the damages hearing, and that the County should not be liable for pre-
judgment interest. As noted above, the County raised only the public policy exception in its
petition for a writ of certiorari and, accordingly, we do not address these other issues.
       12
            The County phrased the question for review as follows:

                 Whether public policy, as clearly delineated in the Baltimore
                 County Charter, the Baltimore County Code, controlling
                 Maryland case law, and the separation of powers doctrine,
                 provides an exception to the enforcement of the arbitration
                 award in this case?

                                              13
citation omitted). Among the limited grounds for vacating an arbitration award is when the

award is contrary to an explicit, dominant, and well-defined public policy. 447 Md. at 194

n.11. The same exception may apply when a party to a collective bargaining agreement fails

to comply with an arbitration award and the prevailing party seeks enforcement of that award

in the courts. See Amalgamated Transit Union v. Mass Transit Administration, 305 Md. 380,

389, 504 A.2d 1132 (1986).

       The County argues that the arbitrator’s decision should not be enforced because it is

contrary to such a public policy. It states that the public policy at issue is the County’s

executive budget process and the County Charter’s requirement that the County government

expend only funds that have been appropriated in accordance with that process. The County

argues that the arbitrator’s decision cannot be enforced because it is at odds with that process,

allegedly because funds were not appropriated for this purpose.

       The County made this same no-appropriation argument in its prior appeal when it

asked the courts to vacate the arbitration award. In the prior appeal, this Court ordered

affirmance of the Circuit Court’s decision, although we did not explicitly address in detail

all of the various arguments advanced by the County.               When the County sought

reconsideration of our decision and highlighted its no-appropriation argument, the Court

declined to change its decision. Unsurprisingly, the Circuit Court and Court of Special

Appeals later concluded that the issue has already been decided in this case and is the “law

of the case.” See 220 Md. App. at 650-62.



                                               14
       In our view, the lower courts were correct. The law of the case doctrine precludes the

County from re-litigating its no-appropriation argument in the context of the enforcement of

the arbitration decision as it lost that argument earlier when the courts considered the validity

of the arbitration award. Moreover, even if the law of the case doctrine did not dictate the

outcome, the result would be the same, as the County’s no-appropriation arguments lacks

merit in this context.

A.     Whether the County’s Argument is Precluded by The Law of the Case

       The Law of the Case Doctrine

       The law of the case doctrine is a “rule of practice, based upon sound policy that when

an issue is once litigated and decided, that should be the end of the matter.” United States

v. United States Smelting Refining & Mining Co., 339 U.S. 186, 198 (1950).13 Under that

doctrine, “once an appellate court rules upon a question presented on appeal, litigants and

lower courts become bound by the ruling, which is considered to be the law of the case.”

Scott v. State, 379 Md. 170, 183, 840 A.2d 715 (2004); see also Garner v. Archers Glen




       13
         This Court has applied this principle since at least the mid-nineteenth century when
it announced that “[t]he decree of this court (on the former trial of this case) ... on all
questions decided by it, was obligatory on the county court, in its proceedings subsequently
had, and, in conforming to such decree, no error can be imputed to it, when its proceedings
are reviewed on the second appeal to this court.” Mong v. Bell, 7 Gill 244, 246 (Md. 1848);
accord, Waters v. Waters, 28 Md. 11, 22 (1867) (“No principle is better established than that
a decision of the Court of Appeals once pronounced in any case is binding upon the Court
below and upon this Court in the subsequent proceedings in the same case, and cannot be
disregarded or called in question.”); Cohill v. Chesapeake & Ohio Canal Co., 177 Md. 412,
425, 10 A.2d 316 (1939).

Partners, Inc., 405 Md. 43, 55, 949 A.2d 639 (2008). It is the country cousin to the more

ornately named doctrines of res judicata, collateral estoppel and stare decisis.14

       A prior statement of a court that is not part of the court’s ruling in the case – i.e., dicta

– is not law of the case that is necessarily binding on a lower court. Garner, 405 Md. at 57-

59. On the other hand, if an issue is clearly presented to the court and, in rendering a

decision, the court necessarily decides that issue, that ruling is law of the case, regardless of

the extent to which the court elaborates its reasoning. Indeed, the doctrine extends to

questions that “could have been raised and argued” in the prior appeal, but were not, so long

as the ruling resolves them. See Fidelity-Baltimore Nat’l Bank & Trust Co. v. John Hancock

Mutual Life Ins. Co., 217 Md. 367, 372, 142 A.2d 796 (1958).

       The law of the case doctrine is not a fixed, immutable doctrine, but more a matter of

“appellate procedure and convenience.” Hawes v. Liberty Homes, Inc., 100 Md. App. 222,

230, 640 A.2d 743 (1994) (Wilner, J.). In the words of Justice Holmes, it “expresses the

practice of courts generally to refuse to reopen what has been decided, not a limit to their

power.” 100 Md. App. at 231 (quoting Messenger v. Anderson, 225 U.S. 436, 444 (1912)).

The purpose of this doctrine is to avoid piecemeal litigation – that is, to prevent litigants from


       14
          See Steinman, Law of the Case: A Judicial Puzzle in Consolidated and Transferred
Cases and in Multidistrict Litigation, 135 U. Penn. L. Rev. 595, 597-612 (1987). Whether
one or the other doctrine pertains in particular circumstances depends on whether the issue
arises in the same case or successive suits involving the same parties, whether there is already
a final judgment or simply a ruling in an ongoing case, and whether the issue relates to the
application of a legal principle to particular facts or relates to a general question of law. Id.
at 597-99 & nn. 8-10; see also Tu v. State, 336 Md. 406, 416, 648 A.2d 993 (1994).

                                                16
prosecuting successive appeals in a case that raises the same questions that were decided in

a prior appeal. Fidelity-Baltimore Nat’l Bank & Trust Co., 217 Md. at 371-72.

       Courts have identified three sets of circumstances in which the law of the case

doctrine is not applied: (1) the evidence in a subsequent trial is substantially different from

what was before the court in the initial appeal; (2) a controlling authority has made a contrary

decision in the interim on the law applicable to the particular issue; or (3) the original

decision was clearly erroneous and adherence to it would work a manifest injustice. Garner,

405 Md. at 56; Turner v. Housing Authority of Baltimore City, 364 Md. 24, 34, 770 A.2d 671

(2001).15

       Whether the law of the case doctrine should be applied in particular circumstances is

a legal question; accordingly, we review a lower court’s invocation of that doctrine without

any special deference. See Scott, 379 Md. at 184-85 (reviewing whether the “law of the

case” doctrine applied to judges on the same trial court under a de novo standard); Goldstein

& Baron Chartered v. Chesley, 375 Md. 244, 260-61, 825 A.2d 985 (2003) (same).




       15
         As courts have sometimes noted, the law of the case doctrine does not apply to the
Court of Appeals to the same extent as the lower courts. See Turner v. Housing Authority
of Baltimore City, 364 Md. 24, 35 n.5, 770 A.2d 671 (2001) (citing cases). In part, this is
because an appellate court is ordinarily not bound by a ruling by a lower court in a case under
appellate review. In addition, consistent with the second exception to the doctrine, the
doctrine defers to a contrary decision on the law by a controlling authority. With respect to
most issues of State law, the Court of Appeals is the “controlling authority” and thus can
trigger that exception itself.

                                              17
       The Law of this Case

       The County argues that the law of the case doctrine does not apply primarily because

our earlier decision addressed the validity of the arbitration award, as opposed to its

enforceability. We disagree. As the Court of Special Appeals observed, our prior decision

was a “final determination that FOP was entitled, as a matter of law, to the judgment to

enforce the arbitration award. That decision necessarily embraced and resolved all of the

issues that the County raised, as well as any other issues that were then available to raise,

challenging the validity of the arbitration award.” 220 Md. App. at 653.

       The County had argued from the outset of the proceedings in the Circuit Court that

the arbitration award was defective and unenforceable for public policy reasons because it

somehow interfered with the County’s executive budget process. See 220 Md. App. at 650-

62. The Circuit Court rejected that argument as part of its award of summary judgment in

favor of the FOP, and the County raised the no-appropriation argument again on appeal. In

issuing a mandate that directed the Court of Special Appeals to affirm the Circuit Court, this

Court implicitly rejected that argument on its merits.           When the County sought

reconsideration of that decision, explicitly on the ground that it would be unenforceable on

the basis of its no-appropriation argument, this Court denied that request. The County then

attempted to raise the same argument to avoid enforcement of the arbitration award. In

rejecting the same argument, the lower courts properly applied the law of the case doctrine.




                                             18
       Whether An Exception to the Law of the Case Doctrine Applies Here

       The County argues we should revisit the no-appropriation argument because

exceptions to the law of the case doctrine preclude its application here. First, the County

argues that evidence presented at the damages hearing on remand was “substantially

different” than at the earlier hearings concerning summary judgment. It is true that the

evidence was different at the damages hearing because the subject of that hearing was

damages rather than liability, although the County also attempted to elicit testimony

concerning the merits of the arbitration award at the hearing. The Circuit Court sustained

objections to such testimony, but it permitted the County to make detailed proffers as to the

anticipated testimony on that subject. The proffered testimony was not substantially different

than what the County had argued in the earlier proceedings. There was nothing new in terms

of the County’s no-appropriation argument.

       With respect to the second exception to the law of the case doctrine, the County

asserts that it is inapplicable as a result of an intervening decision of the United States

Supreme Court, M & G Polymers USA, LLC v. Tackett, 135 S. Ct. 926 (2015). In the

County’s view, the Tackett decision casts doubt on this Court’s earlier decision in this case.

       In Tackett, the Supreme Court held that a collective bargaining agreement that was

silent on the issue of whether it vested certain retirees with lifetime contribution-free health

care benefits should be interpreted under ordinary contract principles. Tackett, 135 S. Ct. at

937. Although the Supreme Court stated that a court should not infer from contractual



                                              19
silence an intent to vest benefits for life, the Court did not itself construe the agreement but

remanded the case for the lower court to do so. A concurring opinion joined by four

members of the Court explicitly noted the possibility that the lower court, upon an

examination of the entire contract in light of appropriate contract principles, would find that

the parties intended such vesting. 135 S. Ct. at 937-38.

       As is evident, the Tackett decision does not relate to the County’s no-appropriation

argument or to the public policy exception for enforcement of an arbitration award . Rather,

the County apparently believes that it undermines the merits of the arbitration award

interpreting the MOUs in this case. Even considered from that perspective, however, Tackett

is distinguishable. In the case before us, we do not have silence as to the duration of the

retiree subsidy (as in the contract in Tackett), but rather specific language in the MOUs that

a retired officer is to receive the subsidy in effect at retirement until age 65 or the retired

officer becomes eligible for Medicare. As the arbitrator concluded, “the unequivocal

language of the MOUs ... is subject to no interpretation other than ... a binding promise to

retirees that the subsidy would remain at whatever level existed at their retirement.” Tackett

thus does not compel a different result from our prior decision in this case.

       Finally, we reject the notion that our earlier decision was “clearly erroneous” or would

work a “manifest injustice.” Accordingly, none of the three exceptions to the law of the case

doctrine apply.




                                              20
       Summary

       The Circuit Court and intermediate appellate court were clearly correct when they

looked to the law of the case doctrine, in part, to resolve the County’s arguments against

enforcement of the arbitration award. And we could do so as well. Nonetheless, as the

County notes, we are not bound by that doctrine in the same way as the Circuit Court and the

Court of Special Appeals. It is also true that we did not elaborate on this issue in our prior

decision. Whether a court’s judgment encroaches on the powers of the other branches of

government is a significant legal question that can be of constitutional dimension in some

cases – although not this one. Accordingly, we shall explain some of the reasons why we

find the County’s no-appropriation argument inappropriate.

B.     Whether the Arbitration Award is Unenforceable as Contrary to Public Policy

       As it has from the outset of this case, the County argues that the arbitration award is

contrary to public policy, as embodied in the County’s executive budget process.16 The

       16
          The County also argues that enforcement of the arbitration award would be contrary
to the public policy embodied in the constitutional separation of powers. See Maryland
Declaration of Rights, Article 8. However, on closer inspection, it appears that this argument
is not addressed to the validity of the arbitration award or its enforceability, but rather to the
measures taken by the Circuit Court to enforce its own judgment – i.e., the show cause order
initiating contempt proceedings that potentially threatened incarceration of County officials
for non-compliance with the court order.

       To the extent that the County is complaining about the Circuit Court’s exercise of its
contempt powers, that was not the question on which the County sought – and we granted
– a writ of certiorari. Thus, under Maryland Rule 8-131(b), we ordinarily would not
consider that issue. In any event, as the Court of Special Appeals held, the propriety of the
show cause order is moot as no one was held in contempt and the County has complied with
the court’s order. 220 Md. App. at 662.

                                               21
County is correct that the executive budget process set forth in the County Charter and

County Code is an important public policy. In some circumstances, it might well provide a

basis for declining to enforce an arbitration award. Such is not the case here, however.

       The County’s Executive Budget Process

       The Baltimore County Charter provides for an executive budget process under which

the County Executive annually submits to the County Council a budget consisting of the

current expense budget, the capital budget and capital program, and budget message.

Baltimore County Charter, §§701-706; see also BCC §10-1-113. Following a public hearing,

the County Council may, with some exceptions, delete or decrease items in the proposed

budget, but may not add or increase items. Charter, §709. The County Council is to adopt

the budget in the form of an Annual Budget and Appropriation Ordinance. Id. The County

Council may also make supplementary appropriations during the course of the fiscal year,

as recommended by the County Executive. Id., §712. County agencies and officials may not

expend money for any purpose “in excess of the amounts appropriated or allotted for the

same general classification of expenditure in the budget ... or in any supplemental

appropriation.” Id., §715. This restriction does not preclude them from entering into

contracts for services beyond the fiscal year in which the contracts are made “provided that

the nature of such transactions reasonably requires the making of such contracts.” Id.

       Collective bargaining agreements with County employees are funded through this

budget process. See Fraternal Order of Police, Lodge No. 4 v. Baltimore County, 340 Md.



                                            22
157, 164-66, 665 A.2d 1029 (1995). As noted earlier, retiree health benefits, whether

determined through collective bargaining or otherwise, are funded through appropriations

to the OPEB Fund. The interplay of the budget process with an arbitration award related to

a collective bargaining agreement depends to some extent on whether the arbitration award

sets the terms of the collective bargaining agreement or simply interprets them – i.e., whether

it precedes or follows the County Council’s action. See id.

       Grievance Arbitration v. Interest Arbitration

       To a certain extent, the County’s no-appropriation argument appears to confuse an

arbitration award resulting from a grievance arbitration – such as the award in this case –

with an arbitration award arising from interest arbitration – such as may occur during

collective bargaining negotiations prior to the budget process. See Mayor & City Council of

Baltimore v. Baltimore City Firefighters Local 734, 136 Md. App. 512, 519 n.2, 766 A.2d

219 (2001).

       A form of interest arbitration is provided in the County Code to resolve impasses in

collective bargaining negotiations. Under BCC §4-5-505, when collective bargaining

negotiations with public safety officers reach an impasse, the matter may be referred to an

arbitrator. The arbitrator’s award becomes the MOU between the County and the union –

an MOU that is subject to the County’s budget process.17 In those circumstances, the County

       17
         The binding arbitration impasse procedures are available only for negotiations with
certain public safety employees; health care issues are specifically excluded from binding
arbitration. BCC §4-502(d)(2).


                                              23
Executive is obligated under the County Code to submit the MOU required by the arbitrator’s

award to the County Council along with legislation to accomplish any appropriations

required by the award. There is no requirement, however, that the County Council enact such

legislation or make the necessary appropriations. See BCC §4-5-505(h)-(i). Under this

regime, the County Council may lawfully decline to fund benefits provided in an MOU

where the terms of the MOU have been set by an arbitration award. See Fraternal Order of

Police, Montgomery County Lodge No. 35 v. Montgomery County, 437 Md. 618, 622-25, 89

A.3d 1093 (2014) (describing Montgomery County Council’s rejection of a provision in

collective bargaining agreement that resulted from arbitration award following impasse in

negotiations).

       If the Council declined to appropriate funds to support such an arbitration award and

a court were to order the County to expend funds to carry out such an arbitration award, the

County’s no-appropriation argument would have some force. But we are not dealing with

such an arbitration award in this case.18

       By contrast, the arbitration award in this case resulted from a grievance arbitration

pursuant to the terms of MOUs that had been agreed to and accepted by the County

Executive and County Council. The purpose of that arbitration was not to set the terms of

an MOU, but to interpret a term of the already agreed-to MOU.


       18
        The record makes reference to an interest arbitration award made as a result of an
impasse in negotiations between the County and FOP on non-health care issues for fiscal year
2008. That award was apparently funded by an appropriation by the County Council.

                                            24
       As recounted above, the County has entered into a series of collective bargaining

agreements with the FOP. There is no dispute that each of those agreements was approved

and accepted by the County Executive and County Council. In addition, as the County Code

provides and as the County acknowledged at oral argument, funds are annually appropriated

to the OPEB Fund to pay the promised future retiree health benefits. The County took the

position that certain retirees were not entitled to what it had promised in those MOUs with

respect to the health insurance subsidy. The County’s position on that particular issue was

determined to be incorrect through the decisionmaking process that it had agreed to abide by

in the MOUs – binding arbitration. This Court upheld that decision. The interpretation of

those MOUs has already been decided. It is evident that the County disagrees with the

arbitrator’s decision and with the prior decision of this Court in this case. This appeal is not

an occasion to re-litigate that decision. Nor is it an occasion for the County to reset the terms

of MOUs it previously agreed to.

       An arbitration award resulting from a grievance arbitration can be found to be invalid

or unenforceable as contrary to an overriding public policy. See, e.g. Prince George’s

County v. Prince George’s County Police Civilian Employees Ass’n, 219 Md. App. 108, 98

A.3d 1094 (2014), aff’d in part and rev’d in part on other grounds, 447 Md. 180, 135 A.3d

347 (2016). It is also conceivable that the overriding public policy could involve a local

government’s budget process when there is no source of appropriated funds from which the




                                               25
local government may make a promised payment. However, in this case, there was such a

source.

       The OPEB Fund

       At the damages hearing in the Circuit Court, the County proffered that its witnesses

would testify that funds had not been appropriated to pay the health insurance subsidy for the

retired officers promised in the MOUs, although the County did not offer any specific

documentation that there was no source of appropriated funds to carry out that promise. As

indicated earlier, health care benefits for retirees are paid from the County’s OPEB Fund,

which consists of funds appropriated by the County government through its budget process.

Indeed, the County paid the judgment in this case – the reimbursement of unpaid health care

costs that were owed under the MOUs – from the OPEB Fund.

       The County’s argument appears to be that, because the County administration takes

the position that its (mistaken) interpretation of the MOUs would have it pay a lower

percentage of the health care costs of these retirees, the funds that the County government

actually appropriated to pay for retiree health benefit costs should not cover part of those

costs. Such an argument could convert any dispute concerning contract or statutory

interpretation with the County into an alleged violation of the executive budget process. For

example, reduced to its essence, any dispute over whether a particular retiree is eligible for




                                             26
benefits under an MOU would turn into a question as to whether the County had theoretically

appropriated funds for the benefits for that particular employee or retiree.19

       Under the County Code, the County makes an annual appropriation to the OPEB Fund

based on an estimate of what will be needed in the future to pay for retiree benefits. As with

any estimate, the amounts appropriated to the Fund may prove higher or lower than what is

ultimately needed, as a result of a variety of factors, including errors in how the estimate is

calculated. It may be that one or more annual appropriations to the OPEB Fund were

affected by the County’s erroneous construction of the MOUs and that the County may have

failed to appropriate sufficient funds to cover all of the benefits that are to be paid out of that

Fund in the future. Whether the fact that the County has belatedly paid these retirees what

it had promised in health care benefits means that there will be less funds for future payments

to other beneficiaries obviously depends on many different factors. If the County Council

should fail to appropriate money to the OPEB Fund needed to pay the obligations for which

the Fund was created, including an arbitration award related to health care benefits, a court

may someday have to weigh competing public policies. But that is not this case. We have

not reached that bridge.




       19
         The County’s no-appropriation argument appears to be premised on the notion that
the appropriation for retiree health benefits is keyed to specific amounts for specific retirees.
However, the County does not necessarily know in advance precisely how the various factors
affecting its liability will play out – e.g., who will retire unexpectedly, who will unexpectedly
not retire, who will die without surviving beneficiaries, etc.

                                                27
       Summary

       An arbitration award may be vacated or declared unenforceable by a court if the award

is in conflict with an explicit, dominant, and well-defined public policy. In a similar fashion,

under the Baltimore County Charter and Baltimore County Code, an interest arbitration

award that sets the terms of a collective bargaining agreement is subject to the County’s

executive budget process.

       An arbitration award that arises from a grievance process under an MOU previously

approved by the County Executive and County Council and that interprets the provisions of

the MOU is not subject to the executive budget process in the same way as an interest

arbitration award that resolves an impasse in negotiations. While in some circumstances such

an award may be unenforceable under the public policy exception, here the award is

enforceable, particularly when there is a source of funds appropriated for the category of

benefits that are the subject of the award.

                                              III

                                         Conclusion

       For the reasons set forth above, we hold:

       1.     The County has advanced its no-appropriation argument as a basis for its

failure to comply with the arbitration award. It previously made the same argument as part

of its effort to have the arbitration award vacated by the courts. The no-appropriation

argument was explicitly rejected by the Circuit Court as part of its decision to award



                                              28
summary judgment against the County – a decision affirmed by this Court in the prior appeal

in this case. Under the law of the case doctrine, the lower courts properly declined to revisit

that issue as none of the exceptions to the law of the case doctrine pertain in this case.

       2.     Even if the law of the case doctrine did not apply, the County’s no-

appropriation argument appears to be premised on a fundamental confusion between interest

arbitration and grievance arbitration. In any event, the County ultimately refunded the

excessive health insurance deductions – premiums that were actually the County’s obligation

under the MOU – from funds appropriated by the County Council for the payment of health
