ORDER
This matter comes on for consideration of appellee’s petition for rehearing and suggestion for rehearing en banc. Upon consideration whereof, the petition for rehearing is denied by the panel that rendered the decision. The Court will, however, amend the opinion filed on December 22,1998 [
The first sentence of the first full paragraph in column two at 164 F.3d at 1269of the West’s Federal Reporter advance sheets (first sentence of first full paragraph on page 20 of our slip opinion) is amended to read: Even in mandamus cases, which inherently involve court discretion, we have often spoken in strong, and occasionally even absolute, language with regard to the court’s duty to enforce agency action mandated by Congress.
The first sentence of the first full paragraph'in column two at164 F.3d at 1274 of the West’s Federal Reporter advance sheets (first sentence of first full paragraph on page 34 of the slip opinion) is amended to read: While we hold that the Secretary must be ordered to comply with his statutory duty to publish a final regulation regarding designation of the critical habitat for the silvery minnow without regard to his preferred priorities, any order now to impose a new deadline for compliance must consider what work is necessary to publish the final rule and how quickly that can be accomplished.
The last paragraph of the opinion, at164 F.3d at 1274 of the West’s Federal Reporter advance sheets (page 35 of the slip opinion) is amended to read: We REVERSE the district court’s denial of plaintiffs’ motion to review agency action, VACATE the stay order, and REMAND to the district court to order the Secretary to publish, as soon as possible, “a final regulation, based on such data as may be available at that time, designating, to the maximum extent prudent,” the critical habitat for the Rio Grande silvery minnow, as is required by 16 U.S.C. § 1533(b)(6)(C)(ii).
An amended copy of this opinion is attached to this order.
A copy of the petition was circulated to all active judges of the court. No judge called for a poll. Consequently, the en banc suggestion is denied.
In 1991, the administrative process was set in motion to list the Rio Grande silvery minnow as an endangered species and designate its critical habitat under the Endangered Species Act of 1973 and its subsequent amendments (“ESA” or “Act”). In July 1994, the Secretary of the Interior (“Secretary”) listed the fish as an endangered species, but failed to issue a rule regarding its critical habitat. By statute, a final rule designating the silvery minnow’s critical habitat was due March 1, 1995. That date passed without a critical habitat designation, and to date the Secretary has not designated the critical habitat for the silvery minnow. On April 4, 1997, two environmental organizations brought an action in federal district court to compel the Secretary to designate the critical habitat for the silvery minnow within 30 days. The Secretary, while admitting that he had violated the timing requirements of the ESA, asked the district court to stay the action until October 1999. The Secretary explained that it was impossible for him to meet all of the ESA deadlines because of a backlog created by a 13-month spending moratorium imposed by Congress which lasted from April 1995 through April 1996. Despite the fact that the Secretary’s duty to designate critical habitat inured before Congress enacted the moratorium and that the Secretary had not fulfilled his duty in the two-and-one-half years since the moratorium expired, the district court credited the Secretary’s impossibility argument, denied the plaintiffs’ motion to review agency action, and granted the Secretary’s motion to stay the case until October 1999. Because the Secretary failed to comply .with a mandatory, non-discretionary duty unambiguously imposed by the ESA, and because the Administrative Procedure Act requires courts to compel agency action unlawfully withheld, we reverse the district court.
I. BACKGROUND
The Rio Grande silvery minnow (Hybog-nathus amarus) is a stout silver fish with emerald reflections reaching lengths of up to 3 /& inches. Historically, it was one of the most abundant and widespread fishes in the Rio Grande basin. See Final Rule To List the Rio Grande Silvery Minnow as an Endangered Species, 59 Fed.Reg. 36, 988, 36,988 (1994) [hereinafter “Final Rule”]. Over the past 30 years, however, due in large part to dam construction and dewatering of a large percentage of its habitat, the silvery minnow’s presence has been reduced to 5% of its historic range. See id. The fish can now be found only along a 170-mile stretch of the middle Rio Grande, extending from the Cochiti Dam, in Sandoval County, New Mexico to the headwaters of the Elephant Butte Reservoir, in Socorro County, New Mexico. See id.
On March 1, 1993, the Fish and Wildlife Service
The Service failed to meet its March 1, 1994 deadline. Over four months later, on July 20, 1994, the Service published a final rule listing the Rio Grande silvery minnow as an endangered species. See Final Rule, 59 Fed.Reg. at 36,988. In its July 20 final rule, the Service explained that it could not make a concurrent designation of the silvery minnow’s critical habitat as the ESA strongly encourages. See ESA, 16 U.S.C. § 1533(a)(3) (“The Secretary ... to the maximum extent prudent and determinable ... shall, concurrently with making a determination ... that a species is an endangered species ... designate any habitat of such species which is then considered to be critical habitat....”). Instead, the Service concluded that the silvery minnow’s critical habitat was “not then determinable,” and thereby extended its deadline to make a critical habitat determination under Section 4(b)(6)(C) of the Act. See Final Rule, 59 Fed.Reg. at 36,-994.
On April 4, 1997, Forest Guardians and Defenders of Wildlife (together “plaintiffs”) filed suit against the Secretary, alleging that his failure to designate the silvery minnow’s critical habitat violated the ESA. Plaintiffs sought both a declaration that the Secretary was in violation of the ESA and an injunction compelling the Secretary to issue a final rule on designation of critical habitat for the silvery minnow within 30 days of the court’s order. In his answer, the Secretary admitted his failure to comply with his statutory duty to designate critical habitat for the silvery minnow, but defended his inaction on the ground that “no resources are available at this time to complete a critical habitat determination for the silvery minnow.”
On July 14,1997, plaintiffs filed a motion captioned Motion for Review of Agency Decision, seeking review of the Secretary’s failure to issue a final decision on the silvery minnow’s critical habitat. This motion expressly requested that the court declare the Secretary in violation of his non-discretionary ESA duties and order him to carry out his duties within 30 days. That same day, the Secretary filed his opposition to the plaintiffs’ motion along with a motion to stay the proceedings until October 30,1999.
The Secretary opposed plaintiffs’ motion to compel a critical habitat designation essentially on the grounds of fiscal impracticability. The Secretary argued that a
Beginning in April 1995 Congress passed a number of spending moratoria, prohibiting the Service from listing species as endangered or threatened and prohibiting the designation of critical habitats for species already listed.
On April 26, 1996, Congress passed an appropriations bill for the Department of the Interior for FY 1996. See Omnibus Consolidated Rescissions and Appropriations Act of 1996, Pub.L. No. 104-134, 110 Stat. 1821 (1996). The bill continued the 1995 moratorium, but contained a provision permitting the President to waive the moratorium. President Clinton waived the moratorium the day he signed the bill into law. The appropriation bill provided the Service with approximately $4 million to carry out its listing and critical habitat designations for the balance of FY 1996.
Díte to these budgetary restrictions, when the Service 'received its funding in April 1996, it was faced with a backlog of 243 proposed species listings on which it was required to make a final determination.
The LPG established a three-tier system for eliminating the Service’s backlog. Critical habitat designations were relegated to the third tier, based on the Service’s conclusion that critical habitat designation provided only a limited increase in protection to a species already listed as endangered or threatened. See 61 Fed.Reg. at 24,727-24,728. Because the Service received only $5 million for Section 4 activi
At the beginning of FY 1998 — October 1, 1997' — Congress had not appropriated funds for the Service’s listing program; thus, the program proceeded under a continuing resolution at FY 1997 listing levels. In response to what it perceived to be continued inadequate funding, the Service extended the FY 1997 LPG into FY 1998. See 62 Fed.Reg. 55,268, 55,269 (1997). On November 14, 1997, Congress enacted the Department of the Interior’s FY 1998 Appropriations Act. See Department of the Interior and Related Agencies Appropriations Act, 1998, Pub.L. No. 105-83, 111 Stat. 1543 (1997). Therein, Congress expressly limited spending on listings and critical habitat determinations to $5.19 million. See id. at 1547. Again concluding that Congress’ allocation was inadequate to accomplish all of its required duties, the Service extended its LPG through the remainder of FY 1998 and into FY 1999. See 63 Fed.Reg. 25,502, 25,509 (1998).
The district court recognized that “it is clear that the ESA has been violated in this case.” Forest Guardians v. Babbitt, No. CIV 97-0453 JC/DJS, at 4. However, the district court deferred to the Secretary’s LPG, persuaded by the Secretary’s claim of fiscal impossibility and the Service’s argument that the LPG served the ESA’s “overarching purposes” — “maximizing species protection and reversing the trends of extinction.” Id. at 5. Thus, though the court “admonishe[d]” the Secretary to ensure that the silvery minnow’s critical habitat was designated “as soon as fiscally possible,” the district court denied plaintiffs’ motion for review of agency decision and granted defendant’s motion to stay proceedings until October 30, 1999. See id. at 6. Plaintiffs filed a timely notice of appeal to this court on November 12, 1997.
This case presents the question whether resource limitations can justify the Secretary’s failure to comply with mandatory, non-discretionary duties imposed by the ESA.
II. JURISDICTION
After an initial review, we ordered the parties to brief the issue whether the district court order is immediately appealable to this court. We now conclude that it is.
“[T]he courts of appeals shall have jurisdiction of appeals from ... [ijnterlocutory orders of the district courts of the United States ... or of the judges thereof, granting, continuing, modifying, refusing or dissolving injunctions28 U.S.C. § 1292(a) (emphasis added). The Tenth Circuit has recognized “two strands of analysis” for § 1292(a)(1) appeals under which we have jurisdiction. See Utah State Dept. of Health v. Kennecott Corp.,
When plaintiffs’ motion is read in conjunction with their complaint, it is clear that plaintiffs were seeking injunctive relief. First, in their complaint, plaintiffs expressly requested an “injunction” ordering the Secretary to “issue a final rule on designation of critical habitat for the minnow within 30 days of this Court’s order.” Likewise, although plaintiffs’ motion before the district court was captioned “Motion for Review of Agency Decision,” it too sought injunctive relief. The plaintiffs expressly requested that the district court “declare that the defendant violated his non-diseretionary duty” and that the district court “order [the Secretary] to carry out [his duty to designate the critical habitat for the Rio Grande silvery minnow] within 30 days of the Court’s order.”
In short, plaintiffs have sought injunctive relief. Even though plaintiffs failed to label their motion in the district court as one for injunction, it is clear from the content of the motion that plaintiffs were seeking injunctive relief.
Alternatively, we have jurisdiction because the district court’s order had the “practical effect” of refusing plaintiffs’ injunction. In order to have appellate jurisdiction under this second strand of analysis, the challenged order must: (1) have “the practical effect of refusing an injunction,” (2) threaten a “‘serious, perhaps irreparable, consequence,’ ” and (3) be “ ‘effectually challenged’ ” only by immediate appeal. Carson v. American Brands, Inc.,
Here, the practical effect of the district court’s order was to deny the injunctive relief sought by plaintiffs. Had plaintiffs’ motion been granted, an injunction would have issued. See Oregon Natural Resources Council, Inc. v. Kantor,
In addition, the consequences of denying plaintiffs’ motion and staying proceedings for over 14 months threatens serious, perhaps irreparable, consequences regarding the continued vitality of the silvery minnow. Despite the Secretary’s argument to the contrary, critical habitat designations serve to protect species vulnerable to extinction. Without a designated critical habitat, the ESA’s requirement that “[e]ach Federal agency shall ... insure that any [of its actions] is not likely to ... result in the destruction or adverse modification of [critical] habitat,” 16 U.S.C. § 1536(a)(2), becomes unenforceable. Congress expressed its opinion regarding the importance of critical habitat designations by requiring, with limited exception, a contemporaneous designation of critical habitat at the time of listing a species as either endangered or threatened. See 16 U.S.C. § 1533(b)(6)(C). Delaying a decision on the Secretary’s duties regarding
Finally, immediate review in this court is necessary to challenge effectually the Secretary’s inaction. Plaintiffs have no other recourse. Without review in this court, the action will be stayed until October 30,1999.
Accordingly, we have jurisdiction to reach the merits of plaintiffs’ appeal.
III. MERITS
A. Standard of Review.
We review the district court’s denial of plaintiffs’ motion to compel agency action de novo.
B. The Endangered Species Act.
First, we consider whether the Secretary was under a statutorily-imposed mandatory deadline to designate the critical habitat for the silvery minnow. As discussed above, with limited exceptions, the ESA requires the Secretary to take final action on species listing and critical habitat designation within one year after he publishes general notice as to a proposed rule, although the Secretary may declare a one-year extension of time to designate critical habitat if certain criteria are met. See ESA, 16 U.S.C. § 1533(b)(6)(A). Here, the Secretary published a proposed rule to list the Rio Grande silvery minnow as endangered and to designate its critical habitat on March 1, 1993. See Proposed Rule to List the Rio Grande Silvery Minnow as Endangered, With Critical Habitat, 58 Fed.Reg. 11821 (1993). Thus, a final rule or notice of a one-year extension respecting the critical habitat for the fish was due on March 1, 1994. On July 20, 1994, the Secretary, pursuant to 16 U.S.C. § 1533(b)(6)(C),
C.The Administrative Procedure Act.
Having determined that the Secretary violated his non-discretionary duty to issue a critical habitat designation for the Rio Grande silvery minnow, we now look to the APA to determine the proper remedy to
1. “Shall” means shall. The Supreme Court and this circuit have made clear that when a statute uses the word “shall,” Congress has imposed a mandatory duty upon the subject of the command. See United States v. Monsanto,
Unpersuaded by the clear language of § 706 and the weight of authority interpreting the imperative nature of “shall,” the Secretary argues that this court is not required to issue an injunction. Instead, the Secretary urges this court to use its equitable discretion to permit his continued non-compliance with the ESA, citing several Supreme Court opinions that hold that even in the face of a government statutory violation, the power to grant or deny injunctive relief rests in the sound discretion of the court. See Amoco Prod. Co. v. Village of Gambell,
While the Supreme Court has made clear that courts should not lightly infer Congress’ intent to curtail the courts’ traditional equitable power to exercise discretion in the granting of injunctive relief, the Court has likewise made clear Congress’ power to curb the courts’ discretion by clear expression. See Weinberger,
Even in mandamus cases, which inherently involve court discretion, we have often spoken in strong, and occasionally even absolute, language with regard to the court’s duty to enforce agency action mandated by Congress. “If, after studying the statute and its legislative history, the court determines that the defendant official has failed to discharge a duty which Congress intended him to perform, the court should compel performance, thus effectuating the congressional purpose.” Estate of Smith v. Heckler,
We believe our “shall”-means-shall approach has been implicitly recognized by the Ninth Circuit.- In Environmental Defense Ctr. v. Babbitt,
On May 1, 1995, EDC filed the instant suit to compel the Secretary to make and publish a final determination. EDC would prevail except for the fact that between the time the Secretary failed to meet the deadline and the time EDC filed suit, Congress passed an appropriations bill which precluded the expenditure of fiscal year 1995 funds on specified activities under the ESA.
Id. at 869 (emphasis added). The Ninth Circuit held that the Secretary had violated his non-discretionary duty to take final action on the California red-legged frog by February 2, 1995. See id. at 872. However, the court recognized that the appropriations rider prevented the Secretary from complying with ESA deadlines. See id.
Notwithstanding the Ninth Circuit’s statement that it would have compelled the Secretary to act absent the moratorium, the Secretary argues that Environmental Defense Center v. Babbitt supports his position that we should excuse his present non-compliance based on resource limitations. He contends that since the Ninth Circuit concluded both (1) that the moratorium did not modify or repeal the Secretary’s duties under the ESA, and (2) that a “lack of available appropriated funds prevented] the Secretary from complying with the [ESA],” id. at 872, that the Ninth Circuit recognized the inadequate resources defense to the motion to compel agency action.
Consequently, we believe that Environmental Defense Center v. Babbitt supports our conclusion that if the Secretary unlawfully withheld agency action or unreasonably delayed it at a time when the moratorium was not in effect, we must compel the Secretary to perform the mandatory duties required by the ESA. With our discretion so limited, we now turn to whether the Secretary’s failure to designate the silvery minnow’s critical habitat within the statutory time frame constitutes agency action unlawfully withheld or unreasonably delayed.
2. “Unlawfully withheld” vs. “unreasonably delayed. ” Courts have given little attention to the distinction between agency action “unlawfully withheld” and agency action “unreasonably delayed” from the drafting of APA. However, that distinction is important in this case because the discretion Congress took away from courts by using “shall” in the first portion of § 706(1) arguably could come back to the courts through Congress’ use of the modifier “unreasonably” as applied to actions “delayed” (as opposed to actions “withheld”) in the second portion of § 706(1).
As with all questions of statutory interpretation, we first look to the text of Congress’ provisions. Unfortunately, the ambiguity of § 706 is the source of our confusion. Section 706 merely sets out the alternative conditions under which a court must compel agency action — i.e., when agency action is “unlawfully withheld” or “unreasonably delayed.” Moreover, neither the APA’s other substantive provisions nor its structure cast light on the meaning of § 706.
Further, notwithstanding the debate concerning the propriety of finding statutory meaning by reference to legislative history, the floor debates and committee reports attendant to the APA provide little guidance regarding any possible distinction between “unlawfully withheld” and “unreasonably delayed.” The Senate Report accompanying the original APA explained only that the judicial review provisions “expressly recognize[] the right of properly interested parties to compel agencies to act where they improvidently refuse to act.”
Clause (A) authorizing a reviewing court to “compel agency action unlawfully withheld or unreasonably delayed”, appears to be a particularized restatement of existing judicial practice under section 262 of the Judicial Code (28 U.S.C. 377).... Orders in the nature of a writ of mandamus have been employed to compel an administrative agency to act, Safeway Stores, Inc. v. Brown, [138 F.2d 278 (Emer.Ct.App.1943) ], ... or to compel an agency or officer to perform a ministerial or non-discretionary act. Clause (A) of section 10(e) was apparently intended to codify these judicial functions.
Obviously, the clause does not purport to empower a court to substitute its discretion for that of an administrative agency.... However, as in Safeway Stores v. Brown, supra, a court may require an agency to take action upon a matter, without directing how it shall act.
Attorney General’s Manual on the Administrative Procedure Act, at 108 (1947). Thus, while the AG’s Manual places the APA’s judicial review provisions in their historical context and clarifies the courts’ power to compel agency action, it sheds no light on the difference between agency action “unlawfully withheld” and “unreasonably delayed.”
In the absence of any clear statutory guidance we will simply apply the most straight forward common sense reading of these two phrases. Thus, if an agency has no concrete deadline establishing a date by which it must act, and instead is governed only by general timing provisions — such as the APA’s general admonition that agencies conclude matters presented to them “within a reasonable time,” see 5 U.S.C. § 555(b) — a court must compel only action that is delayed unreasonably. Conversely, when an entity governed by the APA fails to comply with a statutorily imposed absolute deadline, it has unlawfully withheld agency action and courts, upon proper application, must compel the agency to act.
Thus, the distinction between agency action “unlawfully withheld” and “unreasonably delayed” turns on whether Congress imposed a date-certain deadline on agency action. See Sierra Club v. Thomas,
In support of the contrary position, the Secretary argues that we should exercise our discretion and consider the context surrounding his legislative duty, as the District of Columbia Circuit did under similar circumstances in In re Barr Labs.,
In light of the clear command of § 706, we cannot agree. Section 706 requires that a reviewing court “shall compel agency action ... unreasonably delayed,” and despite the In re Barr court’s contrary conclusion, we believe that once a court deems agency delay unreasonable, it must compel agency action.
Neither TRAC nor any of the cases it relied on to “discern the hexagonal contours of a standard” involved agency inaction in the face of a mandatory statutory deadline.
IV. REMEDY
The Secretary concedes that he failed to perform a non-discretionary duty, but urges us to excuse his failure on the basis of resource limitations and the impossibility of compliance due to the moratorium and insufficient monetary allocations since its expiration.
We are not unsympathetic to the Secretary’s practical predicament. Moreover,
While we appreciate the Secretary’s objective and the difficult position in which Congress has placed him, we believe his impossibility argument is premature. The Secretary’s impossibility defense (based on a generalized claim of inadequate resources) hypothetically could arise at three distinct junctures in the litigation. First, the inadequate resource argument could arise at the duty stage; essentially the claim would be that Congress’ inadequate appropriations relieve the Secretary of his non-discretionary duties under the ESA. This is essentially a “repeal by implication” argument, or more precisely, a “suspension by implication” argument. However, repeals (or suspension) of legislation by implication are disfavored, especially “when the claimed repeal rests solely on an Appropriations Act.”
Second, the inadequate resources defense could arise at the remedy stage; the claim would be that notwithstanding the Secretary’s failure to perform a mandatory duty, lack of resources should cause this court to disregard the mandated statutory remedy. The Secretary does advance this argument, but in light of the lengthy discussion above, we cannot accept it. In sum, we hold that Congress, through 5 U.S.C. § 706, has explicitly removed from the courts the traditional equity balancing that ordinarily attends decisions whether to issue injunctions. In the face of Congress’ clear command, the Secretary’s inadequate resource argument must fail with respect to the appropriate remedy. Section 706 requires us to compel the unlawfully withheld agency action.
Third, the inadequate resources defense could arise at the contempt stage, as a traditional impossibility defense at any subsequent contempt proceeding that may occur if the Secretary fails to comply with an order enjoining him to designate the critical habitat by a time certain. See United States v. Rylander,
V. CONCLUSION
We hold that the Secretary violated his non-discretionary duty by failing to designate the critical habitat for the Rio Grande silvery minnow by the statutory deadline. After all the permissible delays and extensions, the ESA required the Secretary to publish a final critical habitat designation by March 1, 1995. This preceded any appropriations cutback or moratorium on spending. Moreover, the moratorium on funding activities essential for making critical habitat designations ended well over two years ago. In sum, the Secretary unlawfully withheld agency action here, and vre are required by § 706 to compel the Secretary to act.
That said, we are left to work out the details. Concerned by the Secretary’s delay and the prospect of more delay if the case is remanded to the district court, plaintiffs ask this court to order the Secretary to complete the critical habitat determination within 30 days. In support of this remedy, plaintiffs cite nine district court orders requiring the Secretary to comply with statutory obligations, within between 5 and 120 days. ' The plaintiffs, however, cite no case in which a circuit court has set the deadline for compliance.
While we hold that the Secretary must be ordered to comply with his statutory duty to publish a final regulation regarding designation of the critical habitat for the silvery minnow without regard to his preferred priorities, any order now to impose a new deadline for compliance must consider what work is necessary to publish the final rule and how quickly that can be accomplished. Accordingly, we remand the case to the district court with instructions to order the Secretary to issue a final critical habitat designation for the silvery minnow as soon as possible, without regard to the Secretary’s other priorities under the ESA.
For guidance, we refer the district court to the proceedings in Environmental Defense Center v. Babbitt,
We REVERSE the district court’s denial of plaintiffs’ motion to review agency action, VACATE the stay order, and REMAND to the district court to order the Secretary to publish, as soon as possible, “a final regulation, based on such data as may be available at that time, designating, to the maximum extent prudent,” the critical habitat for the Rio Grande silvery minnow, as is required by 16 U.S.C. § 1533(b)(6)(C)(ii).
Notes
. The Fish and Wildlife Service is located in the Department of the Interior and the Secretary has delegated species-listing and habitat designation authority to the Fish and Wildlife Service. See Brief of Appellee, at 5; see also 55 Fed.Reg. 26114, 26122 (1990).
. "Critical habitat” is defined under the ESA as:
(i) the specific areas within the geographical area occupied by the species, at the time it is listed in accordance with the provisions of section 1533 of this title, on which are found those physical or biological features (I) essential to the conservation of the species and (II) which may require special management considerations or protection; and
(ii) specific areas outside the geographical area occupied by the species at the time it is listed in accordance with the provisions of section 1533 of this title, upon a determination by the Secretary that such areas are essential for the conservation of the species.
16 U.S.C. § 1532(5)(A).
. Section 4(b)(6)(C) of the ESA reads:
(C) A final regulation designating critical habitat of an endangered species or a threatened species shall be published concurrently with the final regulation implementing the determination that such species is endangered or threatened, unless the Secretary deems that—
(ii) critical habitat of such species is not then determinable, in which case the Secretary, with respect to the proposed regulation to designate such habitat, may extend the one-year period specified in subparagraph (A) by not more than one additional year, but not later than the close of such additional year the Secretary must publish a final regulation, based on such data as may be available at that time, designating, to the maximum extent prudent, such habitat.
ESA, 16 U.S.C. § 1533(b)(6)(C).
. In this litigation, the district court found, and the Secretary does not contest, that the final statutory deadline to make the critical habitat determination for the Rio Grande silvery minnow was March 1, 1995. See Forest Guardians v. Babbitt, No. CIV 97-0453 JC/DJS (D.N.M. Oct. 23, 1997).
. Listing duties and critical habitat designations are sometimes referred to collectively as Section 4 duties, because they emanate from § 4 of the Endangered Species Act of 1973 and amendments thereto. See Pub.L. No. 93-205, 87 Stat. 884, 886-89 (1973); Pub.L. No. 97-304, 96 Stat. 1411, 1411-13 (1982).
. On April 10, 1995, Congress passed the first such moratorium, Emergency Supplemental Appropriations and Rescissions for the Department of Defense to Preserve and Enhance Military Readiness Act of 1995, Pub.L. No. 104-6, 109 Stat. 73, 86 (1995), which stated in pertinent part:
Of the funds made available under this heading in Public Law 103-322—
(1) $1,500,000 are rescinded from the amounts available for making determinations whether a species is a threatened or endangered species and whether habitat is critical habitat under the [ESA]; and
(2) none of the remaining funds appropriated under that heading may be made available for making a final determination that a species is threatened or endangered or that habitat constitutes critical habitat (except a final determination that a species previously determined to be endangered is no longer endangered but continues to be threatened).
. In addition, the Service had outstanding 182 candidate species whose conservation status needed determination, numerous court orders to take various actions under Section 4 of the ESA, and 57 petitions to list species under the ESA. See 61 Fed Reg. at 24,723.
. The regulation extending the LPG reclassified some Section 4 activities and changed the three-tier system into a four-tier system. See 61 Fed.Reg. at 64,479-64,480. Critical habitat determinations were lowered to the fourth tier. See id. at 64,480.
. This new LPG returned to the three-tier hierarchy, placing critical habitat determination as the lone duty in tier three. See 63 Fed.Reg. at 25,510.
. While in Biodiversity Legal Foundation v. Babbitt,
. The labels of the plaintiff and the district court cannot be dispositive of whether an injunction has been requested or denied. See 11A Charles Alan Wright, Arthur R. Miller & Mary Kay Kane, Federal Practice and Procedure § 2962, at 413 (1995) (''[A] district court may not avoid immediate review of its determination simply by failing to characterize or label its decision as one denying or granting injunctive relief.”).
. The Secretary argues that even if we view the district court's stay as a denial of a motion for injunctive relief-which we do-the standard governing our review should be abuse of discretion. The Secretary takes this standard from Ute Indian Tribe of Uintah & Ouray Reservation v. Utah,
. If the Secretary deems that a critical habitat is not determinable when a final rule regarding species status is issued, this section permits the Secretary to “extend the one-year period specified in subparagraph (A) by not more than one additional year, but not later than the close of such additional year the Secretary must publish a final regulation, based on such data as may be available at that time, designating, to the maximum extent prudent, such habitat.” 15 U.S.C. § 1533(b)(6)(C) (emphasis added).
. We express serious doubt as to the first conclusion, although we need not decide it in this case. We note that when a later duly enacted law of Congress makes impossible compliance with duties imposed by earlier laws, we would impute to Congress knowledge of the earlier laws and the intent to modify them. See Morton v. Mancari,
As to the second conclusion, to the extent that the Ninth Circuit held that a court considering whether to compel an agency to comply with its mandatory, non-discretionary duties should consider available resources when deciding whether to enjoin the agency, we disagree. Of course, courts must consider resource availability; but since we believe our duty to compel agency action is controlled by 5 U.S.C. § 706, which strips courts of their traditional tools of equity, we hold the agency defense of unavailable resources must be reserved as a defense against contempt if an injunction issues. See infra Section III.
. Nor can we find any guidance regarding a distinction in the rest of the United States Code. The terms "unlawfully withheld” and "unreasonably delayed” appear in only two sections of the Code besides the APA. These sections explicitly or in legislative history reference 5 U.S.C. § 706 and provided no further clarification. In 1996, Congress amended the Federal Environmental Pesticide Control Act of 1972 as follows: "If the Administrator fails to notify an applicant within the period of time required under clause (i), the failure shall be considered an agency action unlawfully withheld or unreasonably delayed for purposes of judicial review under chapter 7 of Title 5.” 7 U.S.C. § 136a (h)(3)(F)(ii). In 1989, Congress amended 38 U.S.C. § 7261(a)(2) to read: "(a) In any action brought under this chapter, the Court of Veterans Appeals ... shall .. . compel action of the Secretary unlawfully withheld or unreasonably delayed.” Prior to the amendment, 38 U.S.C. § 7261(a)(2) only required the secretary to compel action "unlawfully withheld.” The amendment added "or unreasonably delayed” to the end of the existing law to bring it into accord with 5 U.S.C. § 706(1). See 135 Cong. Rec. 30,627 (1989) (Explanatory Statement on the Compromise Agreement on H.R. 901, as amended).
. The judicial review provision of the APA which became 5 U.S.C. § 706(1) originally appeared as § 10(e)(A) of the APA in 1946.
. The Safeway Stores case cited in the AG's Manual concluded that if the Administrator should unreasonably delay final action, a court may issue a writ of mandamus directing the Price Administrator to take action upon a pending request. That case appeared, without analysis, to conflate the concepts of "unlawfully withheld” and "unreasonably delayed,” perhaps because the statute it was interpreting had both an absolute time period within which the Price Administrator must act and an additional requirement that the Administrator act "within a reasonable time” within the absolute maximum time fixed for action. See Safeway Stores,
. The six factors the District of Columbia recognized in Telecommunications Research Action Ctr. v. FCC,
(1) the time agencies take to make decisions must be governed by a "rule of reason”; (2) where Congress has provided a timetable or other indication of the speed with which it expects the agency to proceed in the enabling statute, that statutory scheme may supply content for this rule of reason; (3) delays that might be reasonable in the sphere of economic regulation are less tolerable when human health and welfare are at stake; (4) the court should consider the effect of expediting delayed action on agency activities of a higher or competing priority; (5) the court should also take into account the nature and extent of the interests prejudiced by delay; and (6) the court need not "find any impropriety lurking behind agency lassitude in order to hold that agency action is unreasonably delayed.’ ”
. The FCC delay at issue in TRAC was not governed by any mandatory deadline. Instead, the only timing requirement Congress imposed on the FCC was the general APA mandate that agencies decide matters within a reasonable time. See id. at 79. Moreover, none of the cases on which TRAC relies involves mandatory agency deadlines. See Public Citizen Health Research Group v. FDA,
. We distinguish the present circumstances from those in effect during tire moratorium. While the express congressional moratorium was in effect, that congressional enactment constituted an express suspension of the Secretary's listing responsibilities under the ESA. However, once the moratorium expired, the Secretary can no longer point to any extant legislation expressly modifying his duties under the ESA.
