Plaintiff John Doe and a class of similarly situated individuals (hereinafter collectively, “the Doe plaintiffs”) appeal from the September 17, 2004 judgment of the United States Court of Federal Claims dismissing their complaint. Doe v. United States, No. 98-896 C, slip op. (Fed.Cl. Sept. 17, 2004) (“Doe Summary Judgment Order”). The Doe plaintiffs are Department of Justice (“DOJ”) attorneys who sued the government for alleged violations of the overtime provisions of the Federal Employees Pay Act of 1945 (“FEPA”), ch. 212, 59 Stat. 295 (codified as amended at 5 U.S.C. §§ 5542, 5545, 5546 (2000)). 1 The Doe plaintiffs claim that the Court of Federal Claims erred when it dismissed their claims for overtime pay pursuant to 5 U.S.C. § 5542(a), administratively uncontrollable overtime (“AUO”) pay pursuant to 5 U.S.C. § 5545(c)(2), and holiday pay pursuant to 5 U.S.C. § 5546(b). We discern no such error and therefore affirm the judgment of the Court of Federal Claims dismissing the Doe plaintiffs’ complaint.
*1316 BACKGROUND
I.
The Doe plaintiffs are a class of over 9,000 DOJ attorneys who seek pay for overtime work and holiday work performed between 1992 and 1999.
Doe v. United States,
II.
FEPA includes specific provisions governing each of the Doe plaintiffs’ three claims.
Section 5542(a) contains the general eligibility requirements for overtime pay under FEPA. Section 5542(a) provides in relevant part:
For full-time, part-time and intermittent tours of duty, hours of work officially ordered or approved in excess of 40 hours in an administrative workweek, or ... in excess of 8 hours in a day, performed by an employee are overtime work and shall be paid for, except as otherwise provided by this subchapter[.]
5 U.S.C. § 5542(a) (emphasis added). As emphasized above, overtime hours must be “ordered or approved” in order to be compensable. The applicable regulation repeats this requirement by stating that overtime pay must be “[officially ordered or approved.” 5 C.F.R. § 550.111(a)(1) (2006).
2
Section 550.111(c) clarifies that “[o] ver time work in excess of any included in a regularly scheduled administrative workweek may be ordered or approved only
in writing
by an officer or employee to whom this authority has been specifically delegated.” (emphasis added). As we noted in
Doe V,
a regulation substantially similar to the present section 550.111(c) has been in effect since 1945, when FEPA was enacted, until the present.
Pursuant to 5 U.S.C. § 5545(c)(2), the head of an agency may provide AUO pay instead of other forms of premium pay such as overtime pay under section 5542(a). Section 5545(c)(2) provides in relevant part:
The head of an agency, with the approval of the Office of Personnel Management, may provide that—
(2) an employee in a position in which the hours of duty cannot be controlled administratively, and which requires substantial amounts of irregular, unscheduled overtime duty with the employee generally being responsible for recognizing, without supervision, circumstances which require the employee to remain on duty, shall receive premium pay for this duty on an annual basis instead of premium pay provided by other provisions of this subchapter, except for regularly scheduled overtime, night, and Sunday duty, and for holiday duty....
*1317 (emphases added). The Office of Personnel Management (“OPM”) has promulgated regulations governing AUO payment policy at 5 C.F.R. §§ 550.151-.163. Sections 550.154 and 550.162-.163 set forth rates for premium pay for AUO and other payment provisions specific to AUO. Sections 550.151-.153 establish criteria for determining which positions meet the statutory requirements for AUO pay.
Under the regulations, OPM requires that agencies determine prospectively which positions meet the criteria for AUO pay set forth in sections 550.151-.153. Specifically, the applicable regulation states:
The head of each agency, or an official who has been delegated authority to act for the head of an agency in the matter concerned, is responsible for .... [dietermining in accordance with section 5545(c) of Title 5, United States Code, and this subpart, which employees shall receive premium pay on an annual basis under § 550.141 or § 550.151. These determinations may not be retroactive.
5 C.F.R. § 550.161(b).
Pursuant to section 550.161(b), DOJ published Order 1551.4A in 1975. The order sets forth a general policy of providing AUO pay to persons meeting the statutory requirements in a section entitled “POLICY.” Paragraph 6 of the order elaborates on the requirements for receiving AUO pay and repeats much of the language of 5 C.F.R. § 550.151-.153. Paragraph 7 is entitled “AUTHORIZED PERSONS” and provides:
Premium pay under this order may be paid to eligible employees assigned to the classes of positions listed in Appendix 1 to this order. The Assistant Attorney General for Administration will authorize administratively uncontrollable overtime pay for additional classes of positions upon the request of a bureau director which shows that the positions meet the criteria set out in paragraph 6.
Appendix 1 lists 6 positions: (1) Airplane pilot engaged in air-to-ground border patrol activities, (2) Border patrol agent, (3) Criminal investigator, (4) General investigator, GS-9 and above, (5) Officer-in-charge, Immigration and Naturalization Service domestic office, engaged in investigative duties, and (6) Immigration officer, foreign area, engaged in investigative duties. “Attorney” is not listed.
5 U.S.C. § 5546(b) concerns eligibility for holiday pay under FEPA. Section 5546(b) provides in relevant part:
(b) An employee who performs work on a holiday ... is entitled to pay at the rate of his basic pay, plus premium pay at a rate equal to the rate of his basic pay, for that holiday work which is not—
(1) in excess of 8 hours; or
(2) overtime work as defined by section 5542(a) of this title.
The regulations governing authorization for holiday pay provide as follows:
(a) Except as otherwise provided in this subpart, an employee who performs holiday work is entitled to pay at his or her rate of basic pay plus premium pay at a rate equal to his or her rate of basic pay for that holiday work that is not in excess of 8 hours.
(b) An employee is entitled to pay for overtime work on a holiday at the same rate as for overtime work on other days.
(c) An employee who is assigned to duty on a holiday is entitled to pay for at least 2 hours of holiday work.
(d) An employee is not entitled to holiday premium pay while engaged in training, except as provided in § 410.402 of this chapter.
5 C.F.R. § 550.131 (emphasis added). Section 550.132 also concerns holiday pay. It is entitled “Relation to overtime, night, and Sunday pay” and provides:
*1318 (a) Premium pay for holiday work is in addition to overtime pay or night pay differential, or premium pay for Sunday work payable under this subpart and is not included in the rate of basic pay used to compute the overtime pay or night pay differential or premium pay for Sunday work.
(b) Notwithstanding premium pay for holiday work, the number of hours of holiday work are included in determining for overtime pay purposes the total number of hours of work performed in the administrative workweek in which the holiday occurs.
(c) The number of regularly scheduled hours of duty on a holiday that fall within an employee’s basic workweek on which the employee is excused from duty are part of the basic workweek for overtime pay computation purposes.
(emphasis added). “Holiday work” is defined at 5 C.F.R. § 550.103 as “nonovertime work performed by an employee during a regularly scheduled daily tour of duty on a holiday designated in accordance with § 610.202 of this chapter.” Section 610.202 is entitled “Determining the holiday” and sets forth guidelines for determining which day of a week is to be treated as an employee’s holiday.
III.
On March 24, 2000, in
Doe v. United States,
The Doe plaintiffs’ claims for overtime pay under section 5542 and holiday pay under section 5546(b) have already been the subject of several decisions in the Court of Federal Claims and one appeal. On September 1, 2000, the Court of Federal Claims denied the government’s motion to dismiss the Doe plaintiffs’ claims for overtime pay under section 5542(a) and holiday pay under section 5546(b).
Doe v. United States,
We granted the government’s petition for interlocutory appeal,
Doe v. United States,
*1320
Pursuant to our direction in
Doe V,
the Court of Federal Claims directed an entry of summary judgment in favor of the government.
Doe Summary Judgment Order,
slip op. at 1. The Doe plaintiffs then filed a motion for reconsideration before the Court of Federal Claims in which they argued that all three of their claims — for AUO pay, overtime pay, and holiday pay— survived our decision in
Doe V.
The Court of Federal Claims rejected the argument, holding that the doctrine of the law of the case barred reconsideration of the overtime pay claim and that the holiday pay claim was barred by implication.
Doe v. United States,
The Doe plaintiffs now appeal (1) the dismissal of the AUO pay claim in Doe I and (2) the grant of summary judgment in favor of the government on the overtime and holiday pay claims in the Doe Summary Judgment Order. We have jurisdiction over the Doe plaintiffs’ appeal pursuant to 28 U.S.C. § 1295(a)(3).
DISCUSSION
I.
We review de novo the Court of Federal Claims’s grant of summary judgment in favor of the government.
Info. Sys. & Networks Corp. v. United States,
II.
We begin with the Doe plaintiffs’ claims for overtime pay under section 5542. The Doe plaintiffs argue that the Court of Federal Claims erred in dismissing their claims for overtime pay under section 5542 because they had an alternative theory of liability that was not addressed in our decision in
Doe V.
They characterize their alternative theory as an “as applied” challenge to 5 C.F.R. § 550.111(c)’s requirement of written approval for overtime pay. Instead of arguing that 5 C.F.R. § 550.111(c) is invalid, the Doe plaintiffs argue that DOJ effectively eliminated their ability to acquire a written order or approval for working overtime from a higher level official, as required by the regulation. Therefore, they argue, their overtime should be considered authorized and approved. This argument was not foreclosed by
Doe V,
the Doe plaintiffs urge, because it was not raised in the certified order for the interlocutory appeal that led to that decision. They argue that
Doe V
only overruled the
Anderson I
line of cases to the extent that the cases held the writing requirement invalid. In contrast, the Doe plaintiffs argue that the
Doe V
court “said nothing about whether an agency could avoid its obligations under FEPA by refusing to implement a reasonable or rational system for obtaining the very writings the Court held were required.” Appellants’ Br. at 48. Thus, the Doe plaintiffs contend that cases supporting their “as applied” challenge, such as
Adams v. United States,
The Doe plaintiffs also argue that they should be allowed to modify their claims for overtime pay under section 5542 because
Doe V
changed the controlling legal standard. The Doe plaintiffs argue that the fact that
Hansen,
The government counters that
Doe V
forecloses any consideration of the “alternative arguments” presented by the Doe plaintiffs. It recites our holding in
Doe V
that no compensation could be awarded for work that was not “ordered and approved in strict compliance with [section 550.111(c) ].” At the same time, it argues that the Doe plaintiffs are merely repeating the same argument they raised in
Doe V:
that “the governing OPM regulation should be disregarded in light of the government’s asserted misconduct.” In support of this contention, the government recites passages in the Doe plaintiffs’ briefs in the
Doe V
appeal that are nearly identical to passages in the present briefs. Contrary to the Doe plaintiffs’ arguments, the government argues,
Doe V
rejected both the
Anderson
notion that a writing requirement was invalid
and
that equitable considerations, such as the failure to implement a workable system for authorizing overtime, could entitle workers to overtime even without written authorization. Appellee’s Br. at 28-29 (citing
Doe V,
The government contends that the Doe plaintiffs’ request that they be allowed to amend their previous arguments to accommodate a new legal standard should not be entertained. The government argues that the Doe plaintiffs made the same arguments in their petition for a rehearing in Doe V and that because rehearing was not granted in that case, they should not be able to get a rehearing now. Further, the government asserts that the denial of the petition for rehearing was correct because Doe V did not create a new legal standard. Rather, Doe V required compliance with 5 C.F.R. § 550.111(c), which has been in effect since 1945. The government argues that the Doe V panel considered evidence purportedly showing compliance with section 550.111(c)’s writing requirement at the Doe plaintiffs’ request. The government contends that the Doe V panel rejected the Doe plaintiffs’ argument, foreclosing further consideration of the issue.
We agree with the government that
Doe V
previously determined that the Doe plaintiffs do not have a viable claim for overtime pay under section 5542 and therefore forecloses the Doe plaintiffs’ current argument that DOJ’s system for acquiring written authorization pursuant to section 550.111(c) is unreasonable. This “as applied” argument is foreclosed by our finding in
Doe V
that
Anderson I,
The Doe plaintiffs’ reliance on
Adams,
Finally, Doe V does not set forth a new legal standard that might allow the Doe plaintiffs to make new arguments before the trial court under that standard. Hansen and Richmond, which were our bases for finding that Anderson I had been overruled, were decided in 1981 and 1990, respectively. Thus, the Doe plaintiffs knew about Hansen and Richmond before Doe V was decided and had their opportunity to mount arguments under the principles of those cases.
III.
Turning to the Doe plaintiffs’ claim for AUO pay, the Doe plaintiffs argue that the Court of Federal Claims erred in Doe I when it dismissed their claim for AUO pay pursuant to section 5545(c)(2) for lack of jurisdiction. They acknowledge that the statute governing AUO pay contains the discretionary word “may.” Despite this discretionary language, the Doe plaintiffs argue that section 5545(c)(2) is money-mandating for two reasons. First, they argue that the word “may” in section 5545(c)(2) gives the agency the discretion to establish how it will pay overtime, but not whether AUO pay will be paid. Thus, an agency has the choice to elect to pay either overtime pay under section 5542(a) or AUO pay under 5545(c)(2). Although the agency can choose between overtime pay and AUO pay, according to the Doe plaintiffs, the agency must pay for hours worked. The Doe plaintiffs’ second argument as to why section 5545(c)(2) is money-mandating is that once DOJ makes an election to compensate AUO, any employee meeting the statutory requirements must be paid.
With regard to the merits of their claim for AUO pay, the Doe plaintiffs argue that the language of paragraph 5 of DOJ Order 1551.4A makes AUO pay required for all employees whose work requires “substan
*1323
tial amounts of irregular or occasional overtime,” including attorneys. Based on
Hannon v. United States,
The government responds to the Doe plaintiffs’ jurisdictional arguments by noting that the jurisdictional and merits inquiry converge in this case. Even if the court below erred by dismissing on jurisdiction, they argue that dismissal on the merits was required without further hearing.
The government counters the Doe plaintiffs’ arguments on the merits of the AUO pay claim by contending that section 5545(c)(2) gives “the head of an agency” the discretion to decide if any employee is entitled to AUO pay. The government recounts the legislative history of section 5545(c)(2) and the applicable regulations, which expressly state that AUO pay determinations may not be made retroactively. See 5 C.F.R § 550.161(b). If AUO pay cannot be awarded retroactively, the government argues, then the agency must use its discretion to prospectively determine which employees will be awarded AUO pay. The government argues that DOJ did not exercise its discretion to give attorneys AUO pay. The government turns to Appendix 1 to DOJ Order 1551.4A, which the government notes did not list attorneys as a group authorized to receive AUO pay. This list, the government argues, is exclusive because the order sets forth procedures for adding positions to the list. It notes that these procedures were followed when the INS positions mentioned in the 1988 AAGA memorandum were added to the list. Further, the government points out that the 1988 AAGA memorandum authorized AUO pay for “immigration officers,” as defined in 8 C.F.R. § 103.1, but specifically exempted “general attorneys” from coverage. The government also argues that the Doe plaintiffs’ position, if adopted, would effectively nullify DOJ Order 1551.4A, by making it the courts’ duty to determine which positions meet statutory and regulatory requirements for AUO pay.
*1324
The Court of Federal Claims’s jurisdiction pursuant to the Tucker Act is derived from the underlying substantive law that is the subject of a suit.
Samish,
A statute is not money-mandating when it gives the government complete discretion over the decision whether or not to pay an individual or group.
See Doe v. United States,
The first issue before us is whether a statute using the word “may,” as used in 5 U.S.C. § 5545(c)(2), is discretionary. We find that the Doe plaintiffs are correct that 5 U.S.C. § 5545(c)(2) is a money-mandating statute. As previously noted, section 5545(c)(2) provides:
The head of an agency, with the approval of the Office of Personnel Management, may provide that—
(2) an employee in a position in which the hours of duty cannot be controlled administratively, and which requires substantial amounts of irregular, unscheduled overtime duty with the employee generally being responsible for recognizing, without supervision, circumstances which require the employee to remain on duty, shall receive premium *1325 pay for this duty on an annual basis instead of premium pay provided by other provisions of this subchapter, except for regularly scheduled overtime, night, and Sunday duty, and for holiday duty....
By using the word “may,” the statute gives the “head of an agency” the discretion to allow AUO pay for employees in particular positions, although this discretion is somewhat limited because the agency may only award AUO pay to employees in positions that meet the requirements listed in section 5545(c)(2). Further, once the agency makes a determination that a particular position is entitled to AUO pay, the employee “shall” receive premium pay under the statute. Thus, the statute is money-mandating because once a condition is met, namely that the head of an agency states that a position meets the criteria listed in subsection (c)(2), the statute requires payment to employees with that position.
See Fisher,
However, although the court erred in dismissing the Doe plaintiffs’ AUO pay claim for lack of jurisdiction, the error was harmless because the claim should have been dismissed on the merits. While section 5545(c)(2) may be money-mandating once certain conditions are met, the Court of Federal Claims correctly found that it does not require payment to the Doe plaintiffs. The regulations set forth at 5 C.F.R. §§ 550.151-.163 do not state that any person meeting the statutory requirements for AUO pay is entitled to premium pay. Instead, the regulations establish a system whereby agencies must decide if a particular position meets the requirements of the statute before employees with that position may be awarded AUO pay. See 5 C.F.R. § 550.153(a). The regulations require that the head of each agency or a designated person determine which employees meet the statutory requirements for AUO pay prospectively. 5 C.F.R. § 550.161(b). This determination must be based on the criteria set forth at 5 C.F.R. §§ 550.151-.153. Pursuant to this regulatory mandate, DOJ stated in paragraph 7 of DOJ Order 1551.4A that the positions listed in Appendix 1 to the order are covered positions. “Attorney” is not one of the listed covered positions. Contrary to the Doe plaintiffs’ arguments, the Appendix 1 list is an exclusive list except to the extent that positions are authorized to receive AUO pay under the procedures set forth in Paragraph 7 of DOJ Order 1551.4A. Paragraph 7 states that the AAGA “will authorize [AUO] pay for additional classes of positions upon the request of a bureau director which shows that the positions meet the criteria set out in paragraph 6.” Thus, the only way to receive AUO pay for a position not on the Appendix 1 list is by seeking and receiving authorization from the AAGA. Contrary to the Doe plaintiffs’ arguments, the 1988 AAGA memorandum cited in their supplemental authority actually illustrates the exclusive nature of the Appendix 1 list. The 1988 AAGA memorandum followed the procedures set forth in Paragraph 7 of DOJ Order 1551.4A to authorize the position of “immigration officer” as defined in 8 C.F.R. § 103.1 to receive AUO pay. Thus, 5 U.S.C. § 5545(c)(2) does not require payment to all qualified persons once the agency has exercised its discretion to implement a program. Instead, it requires payment once an agency has designated a position as qualified. Here, the agency did not designate “attorney” as a qualified position and the Doe plaintiffs admit that they do not fall under one of the six qualified positions listed in Appendix 1. Therefore, the Doe plaintiffs’ claims should have been dismissed on the merits because, as attorneys, they have no basis for entitle *1326 ment to AUO pay under § 5545(c)(2) or 5 C.F.R. §§ 550.151-163.
Although
Hannon
involves the same statute and the same DOJ order, it is unpersuasive in this case. In
Hannon,
the Court of Federal Claims found that it had jurisdiction under section 5545(c)(2) to hear claims for AUO pay brought by Diversion Investigators for the Drug Enforcement Agency.
IV.
With regard to the Doe plaintiffs’ claim for holiday pay, the Doe plaintiffs argue that their claim was not considered in Doe IV or Doe V and therefore should not have been rejected on summary judgment. They note that the word “holiday” did not even appear in the briefing at the summary judgment stage. Further, the Doe plaintiffs argue that the government conceded that a different standard applies to holiday pay and overtime pay under section 5542. More specifically, they note that the government stated that holiday work must be “scheduled in advance” rather than “ordered or approved” like overtime pay under section 5542. The Doe plaintiffs then dedicate the remainder of their brief to arguments as to why their holiday work was “regularly scheduled.”
The government argues that the Doe plaintiffs’ arguments regarding holiday pay are new on appeal and therefore inappropriate. Further, the government argues that the Doe plaintiffs chose to merge their arguments on holiday pay with their overtime pay arguments and thus submitted themselves to the decision in Doe V. In support of this argument, the government notes that the same arguments about inducement that the Doe plaintiffs made in the Court of Federal Claims in connection with their overtime pay claim under section 5542(a) were made in connection with their holiday pay claim under section 5546(b). The government also argues that the plaintiffs filed a cross-motion for summary judgment rather than a partial motion for summary judgment in Doe IV and therefore expressly joined their holiday pay claim to their overtime pay claim.
Finally, the government argues that if we were to allow the Doe plaintiffs to reopen their holiday pay claims, the claims would fail as a matter of law. In support of this argument, the government points to the legislative history of the holiday pay statute, which it says shows that mere performance of holiday hours without prior formal scheduling does not entitle a person to holiday pay.
Although
Doe III, Doe IV,
and
Doe V
make no mention of the holiday pay claim pursuant to section 5546(b), we agree with the Court of Federal Claims that the Doe plaintiffs’ claim for holiday pay is barred
*1327
by our decision in
Doe V.
Our review of the record reveals that the Doe plaintiffs did not seek to separate their claim for holiday pay from their claim for overtime pay until after
Doe V
issued. In their initial complaint, the Doe plaintiffs stated in their holiday pay count that they had been induced and encouraged to work on holidays, just as they claimed in their overtime count that they were induced and encouraged to work overtime. Compl. at 16, 20. Instead of distinguishing the theory of liability for the holiday pay claim and the overtime pay claim, the Doe plaintiffs explicitly bound the two claims together by filing a motion for summary judgment on liability — not partial summary judgment— and then presenting their inducement and encouragement arguments. The
Doe III
decision thus granted the Doe plaintiffs’ motion for summary judgment on liability for both claims even though only section 5542(a) was explicitly addressed.
CONCLUSION
We affirm the Court of Federal Claims’s entry of summary judgment in favor of the government on the Doe plaintiffs’ section 5542 overtime pay and section 5546(b) holiday pay claims. Although we find that the Court of Federal Claims erred in ruling that it lacked jurisdiction over the Doe plaintiffs’ claim for AUO pay under section 5545(c)(2), the error was harmless because the claim should have been dismissed on the merits. We therefore affirm the court’s dismissal of the Doe plaintiffs’ claim for AUO pay, but find that the dismissal should have been based on the merits of the claim rather than on lack of jurisdiction.
