Opinion for the Court by Circuit Judge ROGERS.
The District of Columbia appeals the denial of a motion pursuant to Rule 60(b)(6) of the Federal Rules of Civil Procedure to vacate an order on dental services under a settlement agreement regarding medical services for children eligible for Medicaid. The district court ruled that the motion was untimely and, alternatively, that the challenge to its authority to order relief exceeding the federal standards underlying the settlement agreement lacked merit in view of its authority to enforce the agreement. On appeal, the District government contends that the district court erred in dismissing the motion as untimely, and abused its discretion by imposing requirements that exceed the parties’ settlement agreement.
The circumstances do not indicate that the motion to vacate was untimely. In the context of institutional reform litigation, which contemplates ongoing district court proceedings as occurred here, the parties continued to attempt to resolve their differences regarding compliance with the dental order, with the district court’s encouragement. On January 27, 2006, the court-appointed monitor filed a report indicating that goals set by the dental order were unrealistic and a new evaluation was warranted. The District government filed its motion to vacate four months later. Nonetheless, the district court could properly find that the District government failed to show the requisite extraordinary circumstances to warrant relief under Rule 60(b)(6). The legal argument that the district court exceeded its authority by requiring the District government to engage in activities to which the parties did not agree and that are not required by federal law could have been raised on appeal from the dental order; the District government noticed an appeal and then withdrew it. Accordingly, we affirm the denial of the Rule 60(b)(6) motion.
I.
This appeal arises in the context of a complex remedial order concerning medical services and assistance provided by the District of Columbia government pursuant to the Medicaid provisions of the Social Security Act, 42 U.S.C. §§ 1396a, 1396d (Chapter 19). On January 22, 1999, the settlement agreement between the plaintiff class (“appellees”) and the District government was approved and entered as an order by the district court. The Settlement Order provides in paragraph 36 that the District government “shall provide or arrange for the provision of early and periodic screening, diagnosis, and treatment (EPSDT) services when they are requested by or on behalf of children.” As relevant, appellees filed two motions to enforce the provisions relating to dental care.
First, on July 3, 2002, appellees moved to enforce Paragraph 36 in part because in 2001 only 30.65% of eligible children received dental services and only 20.55% received preventive dental services. By order entered seven months later, the district court found that the District government was in violation because its own reports showed that “the vast majority of children within the class covered by this litigation who should receive lead blood screening and dental services are not getting them.” Mem. Op. (Feb. 28, 2003) at 1. The District government was ordered to: (1) notify, at least annually, dental care providers of the Medicaid requirements; (2) require each managed care organization to develop a corrective action plan; and (3) mail, by April 15, 2003, to all households in the District of *1113 Columbia with one or more Medicaid-eligible children a written notice describing the dental benefits. The district court also ordered the court-appointed monitor to prepare a report by May 15, 2003 evaluating the effectiveness of these efforts.
Second, after the monitor filed his report on June 17, 2003 recommending improved strategies for the broader provision of dental services, appellees again moved to enforce the Settlement Order on April 23, 2004. Six months later, in view of its conclusion the District government had violated Paragraph 36, the district court ordered various remedial measures to increase the rate at which children were receiving dental care. The District government was ordered to: (1) develop a dental periodicity schedule that complies with generally accepted dental standards; (2) develop a corrective action plan for ensuring that all Medicaid-eligible children receive dental services, including increased provider participation, provider training, and outreach; and (3) meet specific participation goals, ranging from 70% to 85%, depending on age, no later than September 30, 2007. Order of Oct. 18, 2004 (“the Dental Order”).
The District government noted an appeal from the Dental Order on November 16, 2004. On January 27, 2005, however, it moved to hold the appeal in abeyance pending its filing a motion in the district court to “dissolve” the Dental Order. Then, on March 15, 2006, the District government moved to dismiss the appeal, which motion was granted,
see
Order, No. 04-7200,
Four months later, on May 26, 2006, the District government filed a motion to vacate the Dental Order on the ground that the district court had exceeded its authority. The District government argued: (1) the evidence did not support a finding it had violated the Settlement Order by failing to provide and arrange for appropriate dental services upon request; (2) the remedial relief was not tailored to cure a constitutional or federal law violation; (3) it was placed in the position of being an insurer of dental care under an inequitable strict liability standard; and (4) the relief “[vjastly [ejxceeds the [standards set by the [fjederal and [l]ocal [a]gencies [a]dmin~ istering” the Medicaid program for children’s medical care. Memorandum of Points and Authorities in Support of Defendants’ Motion to Vacate Order Granting Injunctive Relief Dated October 18, 2004 at 3-4, Salazar v. District of Columbia, No. 93-cv-452 (D.D.C. May 26, 2006), ECF No. 1153. The motion did not reference the monitor’s January 27, 2006 report although it referred to a 2000 report by the General Accounting Office indicating the limited effect of payment increases on provider participation that was also cited in the monitor’s report.
Additionally, in response to appellees’ opposition, the District government argued that continued enforcement of the Dental Order was unjust and that it was entitled to relief because the Dental Order imposed obligations beyond those negotiated by the parties, and under Rule 60(b)(6) the district court has “a large degree of discretion in granting relief.” 1 Defendants’ Re *1114 ply to Plaintiffs Opposition to Defendants’ Motion to Vacate the Court’s Injunction of October 18, 2004 at 5, Salazar v. District of Columbia, No. 93-cv-452 (D.D.C. Sept. 12, 2006), ECF No. 1219. The reply argued that the monitor’s January 27, 2006 report showed that the Dental Order’s requirement of an 80% participation rate by 2007 is (in the District government’s words) “utterly unrealistic and may not be achievable at all.” Id. at 6. It also noted “the lack of any direct evidence of any member of the plaintiff class having been effectively denied dental services to which they are entitled.” Id. at 7. It concluded:
This is an extreme case, the Dental Order requires the District [government] achieve a result that the Court’s Monitor [h]as opined to be unachievable with tools the Monitor has found unlikely to succeed. Rule 60(b)(6) was designed for just such an occasion.
Id.
The district court denied the motion to vacate on February 18, 2010 (over
3\
years after it was filed). It ruled that the motion was untimely because it was filed nineteen months after the Dental Order was entered, noting the District government’s “inexplicable delay.”
Salazar v. District of Columbia,
The District government appeals, contending that the district court abused its discretion in denying the motion to vacate as untimely and exceeded its authority by imposing requirements in the Dental Order beyond the parties’ settlement agreement.
II.
Federal courts “long ago established” that they “would not alter or set aside their judgments after the expiration of the term at which the judgments were finally entered.”
Hazel-Atlas Glass Co. v. Hartford-Empire Co.,
The Supreme Court, in fashioning Rule 60(b), “took notice of the fact that the terms of the district court may vary in length and that the expiration of the term might occur very soon, or quite a long time, after the entry of a judgment.”
Hazel-Atlas Glass,
In 1938 the Court promulgated a uniform rule permitting a motion to relieve a party from a judgment but requiring that the motion be made “within a reasonable time, but in no case exceeding six months after such judgment, order, or proceeding” and only where the order or proceeding was taken “through [the movant’s] mistake, inadvertence, surprise, or excusable neglect.” Fed.R.Civ.P. 60(b) (1938),
reprinted in
James Wm. Moore & Elizabeth B.A. Rogers,
Federal Relief from Civil Judgments,
55 Yale L.J. 623, 632 (1946). Nonetheless, the “salutary rule as to finality” was retained and, after six months the judgment, order, or proceeding could not be challenged except by a proper collateral action.
Hazel-Atlas,
In 1948, Rule 60(b) was amended to “grant[] courts a broader power to set aside judgments than did the old rule.”
Klapprott v. United States,
A.
“Rule 60(b)(6) ... grants federal courts broad authority to relieve a party from a final judgment ‘upon such terms as are just,’ provided that the motion is made within a reasonable time and is not premised on one of the grounds for relief enumerated in clauses (b)(1) through (b)(5).”
Liljeberg v. Health Servs. Acquisition Corp.,
Rule 60(b)’s concern with finality, embodied originally in the term rule, subsequently in the strict six-month rule, and now in the “reasonable time” requirement, does not carry the same significance in long-running equitable relief as it would in an action where the court’s role had ended and the litigants relied on the repose inherent in the end of litigation. As this court has emphasized, “[t]he power of a court of equity to modify a decree of injunctive relief ... is long-established, broad, and flexible.”
United States v. W. Elec. Co.,
The upsurge in institutional reform litigation since Brown v. Board of Education,347 U.S. 483 [74 S.Ct. 686 ,98 L.Ed. 873 ] (1954), has made the ability of a district court to modify a decree in response to changed circumstances all the more important. Because such decrees often remain in place for extended periods of time, the likelihood of significant changes occurring during the life of the decree is increased.
Rufo v. Inmates of the Suffolk County Jail,
Concluding that a motion to vacate the settlement order or subsequent implementation orders, such as the Dental Order, are subject to a strict time limit would run counter to the policies underlying
Rufo
and its progeny.
Rufo
and
Horne
rejected a “hardening” of the “traditional flexible standard” for modification of injunctions and consent decrees.
Notably, this court has not identified a standard for assessing “reasonable time” under Rule 60(b). It has, however, considered prejudice to the non-moving party. In
Expeditions Unlimited Aquatic Enters., Inc. v. Smithsonian Inst.,
A litigant’s diligence in pursuing review of a decision, either through appeal
*1119
or through Rule 60(b)(6) relief, is relevant in assessing whether extraordinary circumstances are present.
See Gonzalez,
B.
The phrase “extraordinary circumstances” does not appear in the text of Rule 60(b)(6), but the Supreme Court has added this gloss to the rule. The Supreme Court’s earliest interpretations of the 1948 amendment that created Rule 60(b)(6) came in a pair of cases:
Klapprott v. United States,
In
Klapprott,
the Court noted that because the Rule 60(b) motion was brought more than one year after the denaturalization judgment, the petitioner needed to allege more than mere “excusable neglect.”
The basis of his petition was not that he had neglected to act in his own defense, but that in jail as he was, weakened from illness, without a lawyer in the denaturalization proceedings or funds to hire one, disturbed and fully occupied in efforts to protect himself against the gravest criminal charges, he was no more able to defend himself in the [denaturalization proceedings] than he would have been had he never received notice of the charges.
Id.
at 614,
By contrast, in
Aekermann
the Court found unavailing the petitioner’s argument that the denaturalization judgment was erroneous, that the petitioner was without any funds and under threat of losing his home, and that a government officer had apparently misled him. The focus of the Court in
Ackermann
was the fact that petitioner had a “duty to take legal steps to protect his interest in litigation” by appealing.
The Supreme Court has not retreated from this restrictive understanding of Rule 60(b)(6). In
Liljeberg,
the Court treated the phrase “extraordinary circumstances” as a requirement for relief under Rule 60(b)(6),
This court, in turn, has emphasized that Rule 60(b)(6) “ ‘should be only sparingly used’ and may not ‘be employed simply to rescue a litigant from strategic choices that later turn out to be improvident.’ ”
Kramer v. Gates,
The District government relies on
Good Luck Nursing Home,
When a party timely presents a previously undisclosed fact so central to the litigation that it shows the initial judgment to have been manifestly unjust, reconsideration under [R]ule 60(b)(6) is proper even though the original failure to present that information was inexcusable.
Id.
(internal citations omitted). Applying this rule in
Computer Professionals for Social Responsibility v. U.S. Secret Service,
It is unnecessary to decide whether the rule of
Good Luck Nursing Home
and
Computer Professionals
survives the Supreme Court’s decision in
Gonzalez
emphasizing that a “lack of diligence” effectively precludes a finding of “extraordinary circumstance.”
Furthermore, neither
Good Luck Nursing Home
nor
Computer Professionals
involved judgments providing for prospective relief. One sought money for services rendered; the other sought the release of documents. By contrast, the District government sought vacatur of the Dental Order arising under a Settlement Order having prospective application. Where the claim is that the application of an order is prospectively inequitable, Rule 60(b)(5) is available.
See Agostini v. Felton,
Accordingly, we affirm the order denying the District government’s motion to vacate the Dental Order pursuant to Rule 60(b)(6) in the absence of the requisite extraordinary circumstances. The District government is not without remedies, however. Paragraph 71 of the Settlement Order provides for modification “at any time for any reason.” The District government’s legal argument may present a jurisdictional argument cognizable under Rule 60(b)(4), while its impossibility argument may be raised under Rule 60(b)(5).
Notes
. Although the District government's reply also argued that it was entitled to relief under Rule 60(b)(5), it states on appeal that it relied *1114 only on Rule 60(b)(6). See Appellant's Br. 11; Appellee's Br. 21.
. The district court also addressed relief under other provisions of Rule 60(b) and Rules 52 and 59.
See Salazar,
. Rule 60(b) was amended in 1987, but the advisory committee notes describe the amendment as "technical” and that “[n]o substantive change [was] intended.” Fed. R.Civ.P. 60 advisory committee’s note on 1987 amdt. Similarly, Rule 60(b) was amended in 2007 "as part of the general restyling of the Civil Rules to make them more easily understood and to make style and terminology consistent throughout the rules. These changes [were] intended to be stylistic only.” Fed. R.Civ.P. 60 advisory committee’s note on 2007 amdt. The reference in the final sentence that relief is available by a motion or independent action was "deleted as unnecessary.” Id. Rule 60(b)-(e), as presently constituted, reads:
(b) Grounds for Relief from a Final Judgment, Order, or Proceeding. On motion and just terms, the court may relieve a party or its legal representative from a final judgment, order, or proceeding for the following reasons:
(1) mistake, inadvertence, surprise, or excusable neglect;
(2) newly discovered evidence that, with reasonable diligence, could not have been *1116 discovered in time to move for a new trial under Rule 59(b);
(3) fraud (whether previously called intrinsic or extrinsic), misrepresentation, or misconduct by an opposing party;
(4) the judgment is void;
(5) the judgment has been satisfied, released or discharged; it is based on an earlier judgment that has been reversed or vacated; or applying it prospectively is no longer equitable; or
(6) any other reason that justifies relief.
(c) Timing and Effect of the Motion.
(1) Timing. A motion under Rule 60(b) must be made within a reasonable time— and for reasons (1), (2), and (3) no more than a year after the entry of the judgment or order or the date of the proceeding.
(2) Effect on Finality. The motion does not affect the judgment's finality or suspend its operation.
(d) Other Powers to Grant Relief. This rule does not limit a court's power to;
(1) entertain an independent action to relieve a party from a judgment, order, or proceeding;
(2) grant relief under 28 U.S.C. § 1655 to a defendant who was not personally notified of the action; or
(3) set aside a judgment for fraud on the court.
(e) Bills and Writs Abolished. The following are abolished: bills of review, bills in the nature of bills of review, and writs of coram nobis, coram vobis, and audita querela.
. The procedural setting in
Rufo
is instructive. It concerned a 1971 challenge to double bunking of pretrial detainees. An injunction was entered barring double bunking as unconstitutional, and no appeal was taken.
.
See, e.g., Lemoge v. United States,
. To the extent the District government contends that certain aspects of the Dental Order are impossible or impractical to achieve and it is inequitable for the Dental Order to have any prospective application, then its motion may be brought under Rule 60(b)(5), which “permits a party to obtain relief from a judgment or order if, among other things, 'applying [the judgment or order] prospectively is no longer equitable.’ ”
