MEMORANDUM OPINION
The Muwekma Ohlone Tribe (“Muwek-ma,” “the Tribe,” or “the plaintiff’) 2 *107 brings this action under the United States Constitution and the Administrative Procedure Act (“APA”), 5 U.S.C. §§ 554, 701-706 (2000), seeking review of the “Final Determination Against Federal Acknowledgment of the Muwekma Ohlone Tribe” (“Final Determination”), 67 Fed.Reg. 58,-631 (2002), issued by the Department of the Interior (“DOI” or “the Department”), 3 which declined to grant federal recognition to Muwekma as a Native American tribe pursuant to the acknowledgment criteria of 25 C.F.R. § 83 (2006) (“Part 83”). Complaint (“Compl.”) ¶ 1. Specifically, Mu-wekma contends, inter alia, that the Department violated the Equal Protection Clause and the APA by requiring it to undergo the Part 83 acknowledgment procedures while allowing similarly situated tribal petitioners to bypass these procedures altogether. Compl. ¶¶ 37-39; Points and Authorities in Support of Plaintiff’s Motion for Summary Judgment (“Pl.’s Mem.”) at 22-30. Currently before the Court are the parties’ cross-motions for summary judgment. 4 For the reasons set forth below, the Court denies both parties’ motions without prejudice and directs the Department to supplement the administrative record.
I. Background
The following facts are not in dispute. Muwekma is a group of American Indians indigenous to the San Francisco Bay area, the members of which are direct descendants of the historical Mission San Jose Tribe, also known as the Pleasanton or Verona Band of Alameda County (“the Verona Band”). Pl.’s Mem. at 4; Defs.’ Mem. at 5; Answer at 6. From 1914 to 1927, the Verona Band was recognized by the federal government as an Indian tribe. Pl.’s Mem. at 4-5; Defs.’ Mem. at 5; Answer at 12-13. Neither Congress nor any executive agency ever formally withdrew federal recognition of the Verona Band. Pl.’s Mem. at 5; Answer at 14. Nevertheless, after 1927, the federal government no *108 longer acknowledged the Verona Band, or any past or present-day incarnation of the plaintiff, as a federally recognized tribal entity entitled to a government-to-government relationship with the United States. 5 Pl.’s Mem. at 5 (alleging that “sometime after 1927 the Department began to simply ignore the Tribe for many purposes and substantially reduced the benefits and services provided to the Tribe”); Answer at 3 (stating that “the Department does not recognize the Tribe and has not recognized it or any successor of it since 1927”). For example, Muwekma has never been included on the list of federally recognized tribes, first published by the Department in 1979. Pl.’s Mem. at 6; Answer at 14-15.
A. Federal Tribal Recognition
Federal recognition of tribal status “is a prerequisite to the protection, services, and benefits of the Federal government available to Indian tribes” and to the “immunities and privileges available to other federally acknowledged Indian tribes by virtue of their government-to-government relationship with the United States.” 25 C.F.R. § 83.2. Pursuant to statutorily delegated authority, the Department is empowered to determine which currently unrecognized tribes meet the criteria for federal recognition. 25 U.S.C. §§ 2, 9 (2000);
see also James v. HHS,
(a) The petitioner has been identified as an American Indian entity on a substantially continuous basis since 1900....
(b) A predominant portion of the petitioning group comprises a distinct community and has existed as a community from historical times until the present. ...
(c) The petitioner has maintained political influence or authority over its members as an autonomous entity from historical times until the present....
(d) A copy of the group’s present governing document including its membership criteria....
(e) The petitioner’s membership consists of individuals who descend from a historical Indian tribe or from historical *109 Indian tribes which combined and functioned as a single autonomous political entity....
(f) The membership of the petitioning group is composed principally of persons who are not members of any acknowledged North American Indian tribe....
(g) Neither the petitioner nor its members are the subject of congressional legislation that has expressly terminated or forbidden the [fjederal relationship.
Id. Until their 1994 revision, the regulations made no distinction between tribes that had been previously (but not currently) acknowledged and those that had never been federally acknowledged. 6 43 Fed. Reg. 39, 361 (Sept. 5, 1978) (codified at 25 C.F.R. § 54 et seq.) (stating that the regulations are “intended to cover only those American Indian groups ... which are ethnically and culturally identifiable, but which are not currently acknowledged as Indian tribes by the Department”). The revised regulations, however, establish modified criteria for petitioning tribes that can provide substantial evidence of “Unambiguous previous [fjederal acknowledgment.” 25 C.F.R. § 83.8(a). Under the modified criteria, a previously acknowledged tribe needs only demonstrate, inter alia, (1) that it has been identified as an American Indian entity on a substantially continuous basis “since the point of [its] last [fjederal acknowledgment,” 25 C.F.R. § 83.8(d)(1); (2) that “it comprises a distinct community at present,” 25 C.F.R. § 83.8(d)(2); and (3) that “political influence or authority is exercised within the group ... from the point of [its] last [fjed-eral acknowledgment to the present,” 25 C.F.R. § 83.8(d)(3).
B. Muwekma’s Petition for Acknowledgment
In early 1989, Muwekma submitted a letter of intent to petition for federal acknowledgment as an Indian tribe to the Department. Pl.’s Mem. at 11; Defs.’ Mem. at 4. In its response, the Department directed Muwekma to file a formal petition for acknowledgment along with detailed documentation in accordance with the Part 83 criteria. 7 Pl.’s Mem., Exhibit (“Ex.”) 46 (April 25, 1989 letter from Joseph Little to Rosemary Cambra) at 1 (cautioning Muwekma that “[bjecause of the significance and permanence of acknowledgment as a tribe, the process of evaluation is a lengthy and thorough one”). Accordingly, beginning in 1995, Muwekma submitted a formal petition for acknowledgment as well as “thousands of pages” of supplemental material, Pl.’s Mem. at 11, comprising “primary and secondary source documents, genealogical evidence, arguments by its researchers, and responses to *110 questions posed by the Department’s staff,” Defs.’ Mem. at 5. After reviewing Muwekma’s petition and the accompanying materials, the Department concluded preliminarily in May 1996 “that the Pleasan-ton or Verona Band of Alameda County[, from which members of the Muwekma tribe are directly descended,] was previously acknowledged by the federal government between 1914 and 1927.” Defs.’ Mem. at 5; see also Pl.’s Mem. at 11. The Department thus informed Muwekma “that it would be able to complete its petition documentation with the expectation that it would be evaluated under the federal acknowledgment regulations’ modified criteria set out in § 83.8.” Defs.’ Mem. at 5. In early 1998, after further documentary submissions by the plaintiff, the Department concluded that Muwekma’s petition was complete and placed it “on the list of petitions ready for consideration.” Id.; see also Pl.’s Mem. at 11.
After several years during which the Department took no action on Muwekma’s formal Part 83 petition for acknowledgment, another member of this Court determined in June 2000 that the defendants had “unreasonably delayed processing of the Muwekma Tribe’s petition,” calling the delay “unjustifiable and without good reason.”
Muwekma Tribe v. Babbitt,
C. The lone and Lower Lake Ranchería Tribes
In 1994, the Department conferred federal recognition upon the lone Band of Miwok (“lone”), a Central California Indian tribe. PL’s Mem. at 25; id., Exs. 61-63; see also Compl. ¶ 26; Answer at 22. The Department similarly acknowledged the tribal status of the Lower Lake Ranchería of California (“Lower Lake”), another Central California tribe, by placing it on the list of federally recognized *111 tribes in 2001. 9 Pl.’s Mem. at 24; id., Ex. 60; see also Compl. ¶ 26; Answer at 23. Neither lone nor Lower Lake were required by the .Department to submit a formal petition for tribal acknowledgment under Part 83, nor to undergo the “lengthy and thorough” process of evaluation “based on detailed documentation provided by the petitioner,” Pl.’s Mem., Ex. 46, before receiving the benefits of federal tribal recognition. Compl. ¶ 26; Answer at 22, 23 (admitting that the Department “clarified the status of [lone] ... [and] reaffirmed the status of [Lower Lake] without requiring [them] to submit ... petition^] under ... Part 83”); Answer at 30 (admitting that “while the Tribe’s petition for recognition was pending, the Department reaffirmed the status of [lone] and [Lower Lake] outside the [Part 83] procedures”). Moreover, the Department does not dispute Muwekma’s allegation that lone and Lower Lake, like Muwekma, “were ... Central California tribes previously recognized at least as late as 1927” who did not appear on the 1979 list of federally recognized tribes despite “never [having] been terminated by Congress [or] by any official action of [the Department].” PL’s Opp. at 5; see also PL’s Mem. at 23-27; Answer at 22-23.
On several occasions, Muwekma requested that the Department reaffirm its tribal status through administrative correction, as the Department had done with lone and Lower Lake, without requiring that its completed petition be evaluated under the Part 83 criteria. PL’s Mem. at 11; Compl. ¶27; Answer at 23. The Department denied Muwekma’s requests, stating that it did not have the power to restore Muwekma to the list of recognized tribes by administrative means. PL’s Mem. at 11; Compl. ¶ 27; Answer at 23 (admitting that “[n]otwithstanding the Department actions to the contrary with respect to the lone Band and Lower Lake, [Department] staff repeatedly advised [Muwekma] that the Assistant Secretary [of Indian Affairs] lacked authority to administratively reaffirm tribal status”). The Department’s contention to Muwekma notwithstanding, it is important to note that its regulations provide that the Secretary of the Interior “retains the power to waive or make exceptions to [Department regulations pertaining to Indian affairs] in all cases where permitted by law and [where] the Secretary finds that such waiver or exception is in the best interest of the Indians.” 25 C.F.R. § 1.2 (2006). The District of Columbia Circuit, as well as at least one other Circuit, has observed the applicability of 25 C.F.R. § 1.2 to the Part 83 procedures for federal tribal acknowl

Cherokee Nation of Okla. v. Babbitt,
D. The Present Litigation
Muwekma brought this action on June 6, 2003, seeking reversal of the Final Determination, placement on the Department’s list of federally recognized tribes, and other injunctive relief. Compl. at 18. On July 13, 2005, Muwekma moved for summary judgment, alleging, inter alia, that the Department violated the APA and the Equal Protection Clause when it required Muwekma to petition for acknowledgment of its tribal status pursuant to the “lengthy and thorough” regulatory procedures of Part 83, Pl.’s Mem., Ex. 46, despite administratively reaffirming the status of similarly situated tribes without requiring those tribes to undertake the Part 83 process and without sufficient explanation for the disparate treatment. 11 Pl.’s Mem. at 21-22, 26-30; see also Pl.’s Opp. at 9-12; Compl. ¶¶ 37-39, 44-47. Specifically, Mu-wekma contends that “[t]he Department returned Lower Lake and lone to the list of recognized tribes outside of the [Part 83] procedures [while] requiring] Muwek-ma to complete the Part 83 process and then, applying a greater evidentiary burden, denied Muwekma recognition despite [its] significantly stronger case for recognition.” PL’s Mem. at 23; see also PL’s Opp. at 7 (arguing that “the facts of Muwekma, even more than Lower Lake, compel administrative correction and recognition”), 8 (arguing that “the Department relied on findings to reaffirm lone which would have disqualified it for recognition under the standards applied to Muwekma”), 10 (asserting that “Muwekma has provided a much more thorough record of its right to be recognized than lone or Lower Lake”).
In response to Muwekma’s summary judgment motion, the defendants filed a cross-motion for summary judgment on September 12, 2005. See generally Defs.’ Mem. In their motion, the defendants do not deny that lone and Lower Lake were allowed to bypass the “full-throated administrative review” required of Muwekma un *113 der Part 83. Defs.’ Reply at 18; see also Answer at 22, 23, 30. Nor do they offer any express justification for requiring Mu-wekma to proceed through the lengthy federal acknowledgment process while exempting lone and Lower Lake. See generally Answer; Defs.’ Mem.; Defs. Reply. Rather, the defendants assert that the path to federal tribal acknowledgment taken by lone and Lower Lake is immaterial to the plaintiffs complaint. See Defs.’ Mem. at 38-41; Defs.’ Reply at 16-19. They argue (1) that the Department had a rational basis for requiring Muwekma to petition under Part 83, because “[t]he federal acknowledgment regulations are specifically written to address and take into account demonstrations of previous federal acknowledgment,” Defs.’ Mem. at 39-40; (2) that because “groups demonstrating or alleging characteristics similar to [Muwek-ma] are regularly required to proceed through the federal acknowledgment process,” making such a requirement of Mu-wekma was not a departure from agency precedent, Defs.’ Mem. at 40; see also Defs.’ Reply at 17-19; and (3) that at most, Muwekma is asking that lone and Lower Lake be required to undergo the Part 83 procedures, a request for which it lacks standing, Defs.’ Mem. at 41; Defs.’ Reply at 18. For the following reasons, the Court concludes that, on the record before it, it lacks sufficient information about the Department’s decisions to recognize lone and Lower Lake outside of the Part 83 process to resolve Muwekma’s equal protection and APA claims. Accordingly, it remands this case to the Department so that the administrative record may be supplemented on this issue.
II. Standard of Review
A. Summary Judgment
Courts will grant a motion for summary judgment under Federal Rule of Civil Procedure 56(c) only if the moving party has “show[n] that there is no genuine issue as to any material fact and that [it] is entitled to a judgment as a matter of law.” Fed. R.Civ.P. 56(c). When ruling on a Rule 56(c) motion, the Court must view the evidence in the light most favorable to the non-moving party.
Holcomb v. Powell,
The non-moving party, however, cannot rely on “mere allegations or denials.”
Burke v. Gould,
Moreover, “in ruling on cross-motions for summary judgment, the [C]ourt shall grant summary judgment only if one of the moving parties is entitled to judgment as a matter of law upon material facts that are not genuinely disputed.”
Shays v. FEC,
B. Review of Agency Action under the APA
An agency action challenged pursuant to the APA “must be set aside if the action was arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law or if the action failed to meet statutory, procedural, or constitutional requirements.”
Citizens to Preserve Overton Park v. Volpe,
The party challenging agency action has the burden to prove that the action was arbitrary, capricious, or otherwise unlawful.
Hawai’i Orchid Growers Ass’n v. Dep’t of Agric.,
III. Analysis
Both the Equal Protection Clause and the APA prohibit agencies from treating similarly situated petitioners differently without providing a sufficiently reasoned justification for the disparate treatment.
See, e.g., Settles v. U.S. Parole Comm’n,
The defendants contest Muwekma’s argument on several fronts. First, they assert that the Department “had a rational basis for requiring [Muwekma] to proceed through the [Part 83] federal acknowledgment process,” Defs.’ Mem. at 39, because “[t]he federal acknowledgment regulations are specifically written to address and take into account demonstrations of past federal acknowledgment,” id. at 39-40. Second, the defendants argue that the Department has not “treated like cases differently” because “[b]y their very nature, ... federal acknowledgment decisions require highly fact-specific determinations.” Defs.’ Reply at 17. Finally, they claim that Muwekma was not treated differently than similarly situated petitioners, because “groups demonstrating or alleging characteristics similar to [Muwekma] are regularly required to proceed through the federal acknowledgment process,” and therefore requiring Muwekma to complete a Part 83 petition “is undoubtedly in keeping with agency precedent.” Id. at 40; see also Defs.’ Reply at 18 (stating that “[i]n reaching [the Final Determination regarding Muwek-ma’s tribal status], [the defendants clearly followed established procedures”) (citations omitted).
For the following reasons, the Court concludes that the defendants have not articulated a sufficient basis for the Department’s disparate treatment of Mu-wekma and the lone and Lower Lake tribes. First, the fact that “[t]he federal acknowledgment regulations are specifically written to address and take into account demonstrations of past federal acknowledgment,” Defs.’ Mem. at 39-40;
see also
25 C.F.R. § 83.8, provides an avenue, rather than a justification, for the Department’s decision to require Muwekma to complete a Part 83 petition. It is immaterial to Muwekma’s equal protection claim whether the Department can direct tribes who are able to demonstrate previous federal acknowledgment to proceed under Part 83, as the Part 83 procedure clearly provides one method by which the Department may confer federal recognition upon a petitioning tribe, regardless whether that tribe had previously been recognized.
See
25 C.F.R. § 83.8;
see also Burt Lake Band of Ottawa and Chippewa Indians v. Norton,
If the Department were
compelled
to require tribes seeking federal recognition to complete petitions under Part 83&emdash;that is, if it had no discretion to exempt certain tribes from the Part 83 procedures&emdash;then
*117
its argument that “federal acknowledgment regulations specifically take into account demonstrations of previous acknowledgment,” Defs.’ Reply at 17, would carry far more weight in establishing that it had a rational basis for denying Muwekma’s requests to proceed outside the Part 88 framework without explanation of, or reference to, the “departures] from agency precedent” in the cases of lone and Lower Lake,
id.
at 18. Undoubtedly, “[a]n agency is required to follow its own regulations.”
Babbitt,
Indeed, the Department does not, and, in light of 25 C.F.R. § 1.2, effectively cannot, claim that it lacks discretion to pull tribes out of the lengthy Part 83 petition process and allow them to be considered for federal recognition without having to submit thousands of pages of documentary material. While the defendants repeatedly state that the Part 83 criteria are a “mandatory” aspect of the federal acknowledgment regulations, nowhere in the papers submitted to this Court do they assert that the Department has no authority to exempt a petitioning tribe from the regulatory procedure entirely' and determine by some other, less burdensome method that the tribe has demonstrated the necessary historical continuity. See, e.g., Defs.’ Mem. at 32 (arguing that “[b]ecause [Mu-wekma] could not meet the mandatory criteria set out in the resulations, the [F]inal [D]etermination was lawful”); Defs.’ Reply at 15 (stating that “the federal acknowledgment regulations set out seven mandatory criteria that must be established”). That is, the defendants contend that “[t]he federal acknowledgment regulations are a valid exercise of the Department’s authority over Indian affairs,” Defs.’ Mem. at 32 (emphasis added), but take seeming pains to avoid stating that the regulations must be followed, and detailed findings made in accordance with the Part 83 criteria, in every instance before the Department can confer federal recognition upon a petitioning tribe, see, e.g. Defs.’ Reply at 12 (stating that “even a once recognized group must be able to demonstrate that it has maintained tribal relations through the present day”).
In their cross-motion for summary judgment, the defendants reference a Tenth Circuit case which “recently suggested ... that the Department has no authority to acknowledge tribal status outside the process in its acknowledgment regulations.” Defs.’ Mem. at 40 (citing
Norton,
Nevertheless, according to the defendants, the Department has not “treated like cases differently” because “[b]y their very nature, ... federal acknowledgment decisions require highly fact-specific determinations.” Defs.’ Reply at 17. The defendants argue that because “the full body of administrative records regarding [lone and Lower Lake] is not before the Court,” Muwekma cannot establish a violation of the Equal Protection Clause or the APA simply by alleging that it has been treated differently than those tribes.
13
Id.
It is
*119
certainly true that the administrative records for lone and Lower Lake are not before this Court. What matters, however, is whether the Department sufficiently justified
in the administrative record for Muwekma’s tribal petition
its decision to treat Muwekma differently from lone and Lower Lake, and a hand-waving reference to “highly fact-specific determinations” does not free the defendants of this obligation.
Id.; see Tripoli Rocketry Ass’n,
For FERC to utter the words ‘unique facts and circumstances!,] ... as a wand waved over an undifferentiated porridge of facts, leaves regulated parties and a reviewing court completely in the dark as to the core of FERC’s reasoning and its relationship to past precedent.... Without more explanation, it is impossible to say whether FERC has acted reasonably or capriciously.
*120
“The basis for an administrative decision ... must be clear enough to permit effective judicial review. It will not do for a court to be compelled to guess at the theory underlying the agency’s action.”
Int’l Longshoremen’s Ass’n v. Nat’l Mediation Bd.,
The defendants’ reliance on
Hoyl v. Babbitt,
one inconsistent precedent does not entitle an agency litigant to demand that the agency ignore prior and subsequent holdings which have followed a uniform approach.... [The][p]laintiff must do more than point to a single potentially deviant precedent before the reviewing court can find such inconsistency in agency action as to constitute arbitrary treatment of litigants.
First, unlike the plaintiff in
Hoyl,
Mu-wekma does not dispute that granting exemptions from the Part 83 tribal acknowledgment procedures is a matter of the
*121
Department’s discretion.
See
Second, it is not fair to say that the procedure by which the Department refused to recognize Muwekma adheres to “prior and subsequent holdings which have followed a uniform approach” or that Muwekma has merely “point[ed] to a single potentially deviant precedent” in claiming disparate treatment. Defs.’ Reply at 19 (quoting
P.R. Cement Co.,
Thus, the Department here “has never provided a clear and coherent explanation” for its disparate treatment of Muwekma when compared with lone and Lower Lake, nor has it ever, in the administrative record or in the papers before this Court, “articulated the standards that guided” its decision to require Muwekma to submit a petition and documentation under Part 83 while allowing other tribes to bypass the formal tribal recognition procedure altogether.
Tripoli Rocketry Ass’n,
Muwekma argues that rather than remanding these proceedings to the Department, the Court should “compel agency action and resolve the underlying issues in this case” by ordering the Department to place it on the list of federally recognized tribes. Pl.’s Opp. at 18 (internal quotation marks omitted). Specifically, Muwekma contends that (1) remand would be redundant, as the Department has already had an opportunity to address the allegedly disparate treatment at the administrative level following
Muwekma I,
Pl.’s Opp. at 13-14; (2) remand would be futile, because the Department could arrive at “only one conclusion [that] would be supportable,” PL’s Opp. at 14 (quoting
Fogg v. Ashcroft,
In opposing remand, Muwekma first argues that “[d]irect judicial action is proper when an agency ‘again fails’ to satisfy the [C]ourt after an initial remand.” PL’s Opp. at 13 (citation omitted);
see also Greyhound Corp. v. ICC,
*123
Muwekma also argues that remand would be futile because the Department could arrive at “only one conclusion [that] would be supportable.” Pl.’s Opp. at 14 (quoting
Fogg v. Ashcroft,
Finally, Muwekma asserts that remand is inappropriate because the Department “has frustrated and delayed matters” such that it could not be counted upon to proceed forward on its own accord “in anything remotely resembling a timely manner.” Pl.’s Opp. at 15 (internal quotation marks and citations omitted). The Tribe compares this ease to
Greene v. Babbitt,
“[W]hen there is a contemporaneous explanation of the [challenged] agency decision, the validity of that action must stand and fall on the propriety of that finding. ... If that finding is not sustainable on the administrative record made, then the [agency’s] decision must be vacated, and the matter remanded to [it] for further
*124
consideration.”
Vt. Yankee,
Upon remand, the Department must provide a detailed explanation of the reasons for its refusal to waive the Part 83 procedures when evaluating Muwekma’s request for federal tribal recognition, particularly in light of its willingness to “clar-if[y] the status of [lone] ... [and] reaffirm[ ] the status of [Lower Lake] without requiring [them] to submit ... petition^] under ... Part 83.” Answer at 23. Such an explanation may not rely on the fact that a “lengthy and thorough” evaluation of Muwekma’s petition, PL’s Mem., Ex. 46, led the Department to conclude that Mu-wekma failed to satisfy three of the modified Part 83 criteria, see 66 Fed.Reg. 40,-712-14. At issue for the purpose of this remand is not whether the Department correctly evaluated Muwekma’s completed petition under the Part 83 criteria, but whether it had a sufficient basis to require Muwekma to proceed under the heightened evidentiary burden of the Part 83 procedures in the first place, given Mu-wekma’s alleged similarity to lone and Lower Lake. In addition, the Department shall express its position regarding whether it is permitted, under 25 C.F.R. § 1.2 or otherwise, to waive or make exceptions to the Part 83 acknowledgment procedures, *125 and whether this waiver or exception imposes a lesser evidentiary burden on petitioning tribes than the completion of a Part 83 petition.
IV. Conclusion
“When an agency provides a statement of reasons insufficient to permit a court to discern its rationale, or states no reasons at all, the usual remedy is a ‘remand to the agency for additional investigation and explanation.’ ”

ORDER
In accordance with the Memorandum Opinion that accompanies this Order, it is hereby
ORDERED that the plaintiffs motion for summary judgment is DENIED. It is further
ORDERED that the defendants’ cross-motion for summary judgment is DENIED. It is further
ORDERED that this matter is remanded to the Department of the Interior (“the Department”) for the limited purpose of supplementing the administrative record in a manner consistent with the Memorandum Opinion. It is further
ORDERED that during the period in which this matter is remanded, the case shall be administratively closed. It is further
ORDERED that the Court shall retain jurisdiction over this matter and shall require the Department to complete its evaluation and submit a supplement to the administrative record by November 27, 2006. In light of the Department’s past delays, and given the narrow purpose for which this matter is being remanded, the Court will look extremely skeptically on motions for extensions of time. Such motions will not be granted absent extraordinary circumstances. It is further
ORDERED that once the Department has filed its supplemental administrative record, the case will be automatically reopened, and a briefing schedule will be set for the expeditious filing of dispositive motions.

*107
¶ 1; Answer at 2 n. 2. The Court notes, however, that the plaintiff's status as a Native American tribe within the meaning of the federal acknowledgment criteria is the primary point of contention in this litigation. See
Morton v. Mancari,
. The named defendants are (1) Gale Norton, in her official capacity as the Secretary of the Interior ("Secretary”); (2) Aurene Martin, in her capacity as the Acting Assistant Secretary for Indian Affairs; and (3) the Department of the Interior (collectively "the defendants”). As noted supra, Dirk Kempthorne has been substituted for Gale Norton pursuant to Rule 25(d)(1). In addition, Aurene Martin is no longer the Acting Assistant Secretary for Indian Affairs, and the position is currently vacant.
. The following papers have been submitted in connection with these motions: (1) Points and Authorities in Support of Plaintiff's Motion for Summary Judgment ("PL's Mem.”); (2) Memorandum in Support of Defendants' Cross-Motion for Summary Judgment and Response in Opposition to Plaintiffs' Motion for Summaiy Judgment ("Defs.' Mem.”); (3) Reply Brief in Support of Plaintiff's Motion for Summary Judgment and Opposing Defendants' Motion for Summary Judgment ("Pl.’s Opp.”); (4) Reply Memorandum in Support of Defendants' Cross-Motion for Summary Judgment ("Defs.’ Reply”); (5) Plaintiff’s Notice of Supplemental Authority ("PL's Not.”); (6) Defendants’ Response to Plaintiff's Filing of Supplemental Authority ("Defs.' Resp.”); (7) Plaintiff's Second Notice of Supplemental Authority ("PL's Second Not.”); (8) Defendants’ Response to Plaintiff's Second Notice of Supplemental Authority (“Defs.' Second Resp.”); and (9) Plaintiff’s Reply in Support of Second Notice of Supplemental Authority ("PL's Reply to Second Resp.").
. The plaintiff claims that "the Department has ... continued to provide the Tribe limited benefits and services since 1927, evidencing a continued government-to-government relationship.” PL's Mem. at 6-7. The Department contests this characterization, arguing that the examples provided by the plaintiff do not indicate federal recognition of its tribal identity after 1927. Defs.' Mem. at 12-13. Because the Court is remanding this case for the Department to supplement the administrative record, it need not decide at this time whether, and to what extent, the plaintiff received benefits and services after 1927 which suggested that it had been identified by the federal government as an Indian tribe.
. In one instance, the old regulations do implicitly distinguish between tribes that have previously been acknowledged and tribes that have never been acknowledged, stating that the Department has the responsibility to contact "all Indian groups known to the Department ... whose existence has not been previously acknowledged by the Department” and inform them of the newly codified acknowledgment procedure. 43 Fed.Reg. 39,361 (Sept. 5, 1978) (codified at 25 C.F.R. § 54.6(a)).
. According to the plaintiff, the Department’s response stated "that the Tribe was required to petition under [Part 83]. The Department disclosed nothing regarding alternate procedures for securing recognition.” PL's Mem. at 11. The Court notes that the response does not expressly state that Part 83 is the only avenue by which groups may petition the Department for tribal acknowledgment. See PL's Mem., Ex. 46 (April 25, 1989 letter from Joseph Little to Rosemary Cambra). In the absence of any statement by the Department to the contrary, however, such a conclusion is certainly a reasonable inference from the text of the letter, which discusses the Part 83 process in detail and indicates no other means for a tribal petitioner to seek acknowledgment. See id.
. For the parties' account of the Muwekma I and Muwekma II litigation, see Pl.'s Mem. at 12-13 and Defs.’ Mem. at 5-6.
. There is some confusion in the record regarding the year in which the tribal status of Lower Lake was formally acknowledged. See Compl. ¶ 26 (stating that “in 2002, [Lower Lake] ... was reaffirmed by administrative action”); Answer at 23 (admitting that "in December 2000, [the Department] reaffirmed the status of [Lower Lake]”); PL's Mem. at 24 (stating that "[o]n January 3, 2001, the Department announced that it would correct its records to recognize [Lower Lake]") (citing PL's Mem., Ex. 60 (January 3, 2001 DOI news release)). The precise date of Lower Lake's recognition is not material to this litigation, but for convenience the Court will refer to January 3, 2001, the date on which the Department formally stated that it had "reaffirmed the federal trust relationship between the United States and ... [Lower Lake],” as the operative date. Pl.’s Mem., Ex. 60 at 1. The Department also extended federal acknowledgment to two Alaska tribes, without requiring them to proceed through the Part 83 process, at the same time it recognized Lower Lake. Pl.'s Mem. at 24 (citing Pl.’s Mem., Ex. 60); Pl.’s Opp. at 2; Answer at 30 (stating that "the former Assistant Secretary reaffirmed the status of two Alaska Native villages outside the [P]art 83 acknowledgment procedures during the pendency of the Mu-wekma petition”).
. The factual record is silent as to whether the Department made formal findings pursuant to this regulation stating that it would be "in the best interest of the Indians" in the lone or Lower Lake tribes to waive the Part 83 acknowledgment procedures in those instances. 25 C.F.R. § 1.2.
. Muwekma also argues (1) that because the Department lacks the authority "to withdraw recognition of an Indian tribe once recognized, ... [it] unlawfully withdrew [federal tribal] recognition of the Muwekma Ohione tribe” when it issued its Final Determination, Compl. KV 34; see also PL’s Mem. at 15-17; (2) that the Final Determination and the failure to include Muwekma on the Department’s annual list of federally recognized tribes constituted an unlawful breach of the Department’s trust relationship with Muwekma, Compl. ¶ 35; see also PL’s Mem. at 17-21; (3) that the Department "unlawfully failed to include [it] in the annual list of federally recognized Indian tribes ... after [it] determined that [Muwekma] and the Verona Band were one and the same,” Compl. ¶ 36; (4) that the Department was biased against Muwekma in a manner which violated Muwekma’s constitutional right to due process, the APA, and 5 U.S.C. § 554(d) (2000), Compl. ¶¶ 40-43; see also Pl.’s Mem. at 30-34; and (5) that the Department arbitrarily and capriciously applied incorrect evidentiary standards in violation of the APA and failed to consider substantial evidence of Muwekma's tribal status when rejecting its Part 83 petition in the Final Determination, Compl. ¶¶ 44-47; see also PL’s Mem. at 35-45. Because the Court is remanding this case to the Department to supplement the administrative record on Mu-wekma’s claims of disparate treatment, it need not address Muwekma's other claims at this time.
. In addition, the Department's representation to Muwekma that it lacked the authority to confer federal recognition on the tribe outside of the Part 83 acknowledgment process, see Answer at 23 (admitting that "[n]otwith-standing the Department actions to the contrary with respect to the lone Band and Lower Lake, [Department] staff repeatedly advised [Muwekma] that the Assistant Secretary [of Indian Affairs] lacked authority to administratively reaffirm tribal status”), appears from the Department’s own admission to be patently false, unless (1) the officers who allowed lone and Lower Lake to bypass formal review under Part 83 were acting beyond the limits of the Department's power, which is difficult to credit, given 25 C.F.R. § 1.2, or (2) the Department has some principled basis for distinguishing Muwekma from lone and Lower Lake such that it was compelled to direct Muwekma to proceed through Part 83, but was free to disregard the regulatory framework when dealing with the other two tribes. Yet, as already noted, the Department appears to avoid stating in its submissions to the Court that it has no power to allow tribal petitioners to bypass the Part 83 procedures, and it offers no express justification for treating Muwekma differently from lone, Lower Lake, or any other tribal petitioner who has been exempted from making a formal petition under Part 83.
. The defendants, albeit obliquely, do provide an asserted basis for distinguishing Mu-wekma and Lower Lake in their reply to Muwekma’s opposition to their cross-motion for summary judgment, stating:
In any event, the administrative record[] itself[ ] points out differences between the Lower Lake Ranchería and [the][p]laintiff. The [Advisory Council on California Indian Policy’s] Final Reports and Recommendations found that the Lower Lake Ranchería was a federally recognized tribe as evidenced by the previous acquisition of land *119 in trust for the Lower Lake Rancheria’s benefit, as well as the tribe’s participation in an [Indian Reorganization Act] election. ... The Report does not make a similar recommendation regarding [the] [plaintiff.
Defs.’ Reply at 17 n. 17. However, this explanation fails to serve as a sufficient justification for the Department's allegedly differential treatment of Muwekma for several reasons. First, and most obviously,'this explanation pertains only to a difference between Muwekma and
one
of the tribes with whom it is claiming to be similarly situated. The defendants do not assert any "highly fact-specific determination[ ]” that would explain why Muwekma is not similarly situated to lone in such a way as to require a reasoned explanation of the Department's disparate actions. Second, the Department does not contend, here or in the administrative record, that it required Muwekma and not Lower Lake to undergo the Part 83 procedure
because
the latter, unlike the former, had received land in trust and had participated in an election.
See Bowman Transp.,
. The defendants argue that
Wyandotte Nation
is inapposite because the Department in this case "has not required [Muwekma] to satisfy criteria not required of either the Lower Lake Ranchería or the lone Band of Mi-wok; namely, the continuity of tribal relations.” Defs.' Second Resp. at 1. However, Muwekma does not allege that lone and Lower Lake were not required to demonstrate continuity of tribal relations. Rather, the Tribe claims, and the Department does not dispute, that it was subjected to a "greater evidentiary burden” than lone and Lower Lake when it was forced to seek tribal recognition through the cumbersome and detailed Part 83 procedures rather than through an alternative administrative route. Pl.'s Mem. at 23. Indeed, it is Muwekma’s central contention that it would have been able to demonstrate the requisite tribal continuity had its request for recognition been evaluated under the standard used for lone and Lower Lake.
See, e.g.,
Pl.’s Opp. at 10 (asserting that "Mu-wekma has provided a much more thorough record of its right to be recognized than lone or Lower Lake"). It may be that the standard imposed upon lone and Lower Lake in their requests for recognition was no less stringent or exacting than the "lengthy and thorough”
*120
process of evaluation followed by the Department in Muwekma's Part 83 petition. Pl.'s Mem., Ex. 46. If so, however, it is not reflected in the administrative record in this case, nor in the pleadings before the Court.
See
Defs.' Reply at 17 (noting that "the full body of administrative records regarding [lone and Lower Lake] is not before the Court”). Thus, on the strength of the factual record before it, the Court is not persuaded by the defendants’ argument that the Department "has not required [Muwekma] to satisfy criteria not required of [Lower Lake] or [lone],” Defs.’ Second Resp. at 1, especially in light of the defendants' failure to "cogently explain why it has exercised its discretion in a given manner,”
State Farm,
. The Court's determination that this case must be remanded so that the defendants may supplement the administrative record in no way contradicts the Court's previous Order granting the defendants’ Motion for Protective Order Against Plaintiff's Discovery Requests. See Dkt. No. 33 (June 13, 2005 Order). In that Order, the Court concluded that Muwek-ma was not entitled to factual discovery of matters outside of the administrative record, in part because it "[had] not presented any evidence that support[ed][its] claim that [it is] similarly situated to other tribes, or that [it was] treated differently.”
Id.
at 6. However, not only has Muwekma now adduced facts to show that the Department has failed to adequately explain its differential treatment of tribal petitioners that
appear
to be similarly situated,
see
PL’s Mem. at 23-28, but the Department does not dispute that Muwekma was required to undergo a more strenuous process in seeking tribal recognition than other tribes evaluated outside of the Part 83 procedures, nor does it offer a reason for exercising its discretion in the manner it did,
see State Farm,
. An Order consistent with the Court’s ruling accompanies this Memorandum Opinion.
