JURISDICTION The judgment of the court of appeals was entered on October 14, 1983. A timely petition for rehearing was denied on Januray 17, 1984. By order of April 12, 1984, the Chief Justice extended the time within which to file a petition for a writ of certiorari until May 16, 1984. The jurisdiction of this Court is invoked under 28 U.S.C. 1254(a). STATUTES INVOLVED Relevant provisions of the Administrative Procedure Act, 5 U.S.C. 551 et seq., and the Food, Drug, and Cosmetic Act (FDCA), 21 U.S.C. 301 et seq., are reprinted at App., infra, 95a-96a. QUESTIONS PRESENTED 1. Whether the Administrative Procedure Act, 5 U.S.C. 701-706, authorizes judicial review of the Food and Drug Administration's decision not to regulate the states' use, in carrying out capital punishment by lethal injection, of drugs that have been approved for other purposes but that have not been found to be "safe and effective" as a means of causing death. 2. If the FDA'S decision not to regulate the states' use of drugs in carrying out capital punishment by lethal injection is subject to judicial review, whether that decision was properly overturned. STATEMENT In recent years, numerous states have enacted statutes prescribing lethal injection as the method for carrying out the death penalty. /1/ In this case, prison inmates sentenced to death by lethal injection in Texas and Oklahoma petitioned the Food and Drug Administration (FDA) to block their executions on the ground that the states proposed to employ drugs that had been approved by the FDA as safe and effective for medical purposes but not for human execution. Respondents asserted that their execution by this means would violate the "misbranding" provisions of the Food, Drug, and Cosmetic Act (FDCA), 21 U.S.C. 331(k), 352. They requested the FDA, among other things, to "(a)dopt a policy and procedure for the seizure and condemnation from prisons or state departments of corrections of drugs which are destined or held for use as a means of execution" and to recommend the criminal prosecution of prison officials and others who "knowingly buy, possess, (sell) or use drugs for the unapproved use of lethal injections" (App., infra, 6a). The FDA declined to take the requested enforcement actions. It concluded (App., infra, 81a-86a) that it lacked jurisdiction under the FDCA and that, in any event, it would decline to act as a matter of its enforcement discretion. The Commissioner of Food and Drugs stated (id. at 82a, 85a); Our conclusion that the use of lethal injection is not subject to our jurisdiction is supported by the relevant statutory provisions, by our current policy on the use of approved drugs for unapproved uses, and by a consideration of the proper role of the Federal Government with respect to the conduct of State criminal justice systems. * * * * * The unapproved use of approved drugs is an area in which the case law is far from uniform. Generally, enforcement proceedings in this area are initiated only when there is a serious danger to the public health or a blatant scheme to defraud. We cannot conclude that those dangers are present under State lethal injection laws, which are duly authorized statutory enactments in furtherance of proper state functions. Were FDA clearly to have jurisdiction in this area, moreover, we believe we would be authorized to decline to exercise it under our inherent discretion to decline to pursue certain enforcement matters. Plaintiffs then brought this suit for injunctive and declaratory relief in the United States District Court for the District of Columbia. The district court dismissed the complaint on the ground that the enforcement decisions of an agency are not subject to judicial review. App., infra, 63a-79a. A divided panel of the court of appeals vacated the district court's judgment and remanded with directions "to order the agency to fulfill its statutory function" (App., infra, 36a). The court of appeals concluded that the FDA has authority under 21 U.S.C. 331(k) to regulate the use of drugs in administering capital punishment. That provision prohibits the "misbranding" of drugs while they are "held for sale." The court apparently reasoned (App., infra, 14a-15a) that the states' use of the drugs for an unapproved purpose constitutes "misbranding" and that the drugs are "held for sale" when they are injected into the person condemned to death. The court of appeals also held that the FDA'S decision not to initiate enforcement activity was subject to judicial review (App., infra, 17a-30a). In the court's view (id. at 18a-22a), all agency action, including a decision not to begin enforcement proceedings, is presumptively reviewable except in those situations "where the governing statute is 'drawn in such broad terms that in a given case there is no law to apply.'" The court observed (id. at 24a) that the "determination of whether there 'is law to apply' turns on such pragmatic considerations as whether judicial supervision is necessary to safeguard plaintiff's interests, whether judicial review will unnecessarily impede the agency in effectively carrying out its congressionally assigned role, and whether the issues are appropriate for judicial review.'" In this case, the court found "law to apply" in the preface to an FDA rule proposed for notice and comment in 1972 but never promulgated. /2/ The court concluded (id. at 31a-35a) that the FDA'S reasons for declining enforcement were irrational in light of the preface and warned (id. at 37a): "We must be prepared to compel FDA to take action with respect to the (plaintiffs') prayer for relief where an acceptable explanation of (FDA'S) inaction is not promptly forthcoming." /3/ Judge Scalia dissented (App., infra, 39a-58a), stating (id. at 39a) that the majority's decision constituted "a clear intrusion upon powers that belong to Congress, the Executive Branch, and the states." He pointed out (id. at 46a) that "far from there being a 'presumption of reviewability' with regard to enforcement determinations, the well known presumption is precisely the contrary." Finding no special circumstances justifying review in this case, Judge Scalia concluded that review was unavailable. He noted (id. at 49a-51a) that the preamble on which the majority relied had never been adopted. He also observed (id. at 48a-49a) that even if the preamble had some effect, it was "full of flexible terms, the precise application of which was obviously intended to be, and could properly be, left to the discretion of the agency -- for example whether an unapproved use has become 'widespread.'" Moreover, assuming that the FDA'S decision not to undertake enforcement action was judicially reviewable, Judge Scalia found (App., infra, 51a-58a) that the FDA'S actions were not arbitrary and capricious. He concluded that the FDA had no statutory authority to take the requested action because "(u)nder no conceivable interpretation of the English language could (the drugs used in legal injections) be deemed 'held for sale'" (id. at 55a). By a five-to-five vote, the court of appeals denied the government's suggestion for rehearing en banc (App., infra, 59a-60a). /4/ In a statement joined by Judges Wilkey, Bork, and Starr, Judge Scalia stressed (id. at 60a) the significance of the holding of this case to "the enforcement authority of all federal agencies." REASONS FOR GRANTING THE PETITION The decision of the court of appeals is in direct conflict with decisions of two other circuits. It usurps the traditional enforcement discretion of the executive branch and diverts the Food and Drug Administration from the important responsibilities assigned by Congress; it unjustifiably interferes with the states' lawful exercise of their power to enforce their criminal laws; and it makes a mockery of the Food, Drug, and Cosmetic Act. Review by this Court is clearly warranted. 1. The decision below squarely conflicts with decisions of the Fifth and Eighth Circuits. In O'Bryan v. McKaskle, 729 F.2d 991 (1984) (App., infra, 88a-94a), a Texas prisoner sentenced to death by lethal injection brought suit against the state authorities, claiming among other things that execution by lethal injection violated the Food, Drug, and Cosmetic Act as interpreted by the court of appeals in the instant case. Refusing to stay his execution, the Fifth Circuit expressly disagreed with the court of appeals' decision in this case (App., infra, 92a-93a): On theprobable merits of O'Bryan's claim of a violation of the Act, we think that for the reasons set forth in Judge Scalia's dissenting opinion in Chaney, O'Bryan's claim is insubstantial and he is unlikely to succeed on appeal. This Court also refused to enter a stay (O'Bryan v. McKaskle, Nos. A-786 and A-787 (Mar. 30, 1984)), /5/ and O'Bryan was executed. The court of appeals' holding concerning judicial review of FDA enforcement decisions conflicts with the Eighth Circuit's decision in National Milk Producers Federation v. Harris, 653 F.2d 339, 340 (1981). In that case, dairy producers sought to compel the FDA to initiate "investigative, enforcement, or prosecutorial proceedings" against persons alleged to be violating the FDCA by selling misbranded cheese substitutes in interstate commerce. Affirming the dismissal of the dairy producers' complaint, the Eighth Circuit stated (653 F.2d at 343) that "(t)he executive branch and its departments enjoy a discretion in the initiation of * * * enforcement * * * actions limited only by constitutional strictures and relevant statutory directives." The court concluded (id. at 344 (footnote omitted)): "After carefully reviewing the (FDCA) we have found no provision which narrows or limits the discretion of the FDA to investigate, enforce, or prosecute alleged violations of the Act or its regulations." 2. a. The court of appeals' decision in this case is also plainly wrong. First, in holding that the FDA'S exercise of enforcement discretion was subject to judicial review, the court departed dramatically from settled principles of adminstrative law. The Administrative Procedure Act, 5 U.S.C. 701(a)(2), provides that final agency action is not subject to judicial review if it is "committed to agency discretion by law." This bar to judicial review applies where the governing "'statutes are drawn in such broad terms that in a given case there is no law to apply.'" Citizens to Preserve Overton Park v. Volpe, 401 U.S. 402, 410 (1971) (quoting S. Rep. 752, 79th Cong., 1st Sess. 26 (1945)). This is a paradigmatic case in which the governing statute provides "no law to apply." The FDCA does not command the FDA to initiate investigative or enforcement activity whenever a statutory violation is alleged or found. /6/ Indeed, the Act does not even suggest the standards to be used by the FDA in determining whether and when to undertake such activity. Instead, the Act confers upon the Commissioner of Food and Drugs a "broad discretion -- broad enough undoubtedly to enable him to perform his duties fairly without wasting his efforts on what may be no more than technical infractions of the law." United States v. Sullivan, 332 U.S. 689, 694 (1948). See also 21 C.F.R. 10.45(d)(2)(i) (initiation of FDA enforcement proceedings discretionary). Because most statutes granting enforcement powers to administrative agencies are cast in similar terms, it is well established that agency enforcement decisions are not subject to judicial review, absent special circumstances. /7/ See, e.g., Southern Ry. v. Seaboard Allied Milling Corp; 442 U.S. 444, 455-456 (1979) (ICC); Vaca v. Sipes, 386 U.S. 171, 182 (1967) (NLRB); see also United States v. Batchelder, 442 U.S. 114, 124 (1979) (criminal prosecution); Bordenkircher v. Hayes, 434 U.S. 357, 364 (1978) (same); Confiscation Cases, 74 U.S. (7 Wall.) 454 (1869) (forfeiture proceedings). In concluding that the FDA'S decision here was judicially reviewable, the court of appeals started (App., infra, 18a) from a presumption of reviewability that stood this case law on its head. The court then offered the startling suggestion (id. at 24a (emphasis added)) that whether there is "law to apply" turns on various "pragmatic considerations," such as the need for judicial supervision to safeguard the plaintiffs' interests, the impact of review on the agency's effectiveness, and the appropriateness of the issues raised for judicial review. This formulation converts a straightforward question of statutory interpretation -- whether Congress intended the courts to review an agency's enforcement decisions -- into an essentially standardless, legislative decision -- whether, in the court's judgment, such review would be beneficial. As Judge Scalia noted in his dissent from the denial of rehearing en banc (App., infra, 61a), this test means that the court is free to intervene whenever it "think(s) it a good idea." The court of appeals found no need to "delve into a detailed analysis" of "pragmatic considerations" in the present case because it determined (App., infra, 24a) that the FDA had "made law to govern and guide its discretion in regulating the unapproved use of approved drugs." But the "law" upon which the court relied was the preamble to a rule that was proposed for notice and comment /8/ but was never adopted by the agency. This unadopted preamble obviously was never intended to be a definitive, judicially enforceable statement of how the agency would exercise its enforcement discretion. As Judge Scalia noted in dissent (App., infra, 48a-49a), the preamble was full of flexible terms that are not susceptible to judicial review. The preamble stated (see id. at 24a (emphasis added)), for example, that "(w)here the unapproved use of an approved new drug becomes widespread or endangers the public health, the Food and Drug Administration is obligated to investigate it thoroughly and to take whatever action is warranted to protect the public health." What is "widespread" use? What constitutes a sufficient danger to the public health? And in a given case, what action is "warranted"? It is evident that these questions cannot be answered intelligently without surveying the potential dangers posed by all the foods and drugs marketed in this country and all the resources at the FDA'S command. We do not see how the courts could perform that function without taking over day-to-day operation of the agency. In sum, the FDA'S decision not to initiate enforcement action in this case was committed to agency discretion by law and therefore was not judicially reviewable. The court of appeals' contrary conclusion, as Judge Scalia observed, "usurps the authority of the Executive Branch" and "rests upon a novel interpretation of Supreme Court precedent" (App., infra, 60a). b. Even if the FDA'S decision were reviewable, it nonetheless should have been upheld. In those special circumstances in which judicial review of administrative enforcement decisions is allowed, the scope of review is limited to determining whether the agency has stated a rational basis for its decision. Dunlop v. Bachowski, 421 U.S. 560, 568, 572-t573 (1975). That standard was easily met here. First, the FDA was correct in finding that it lacked authority to prevent the states from employing the drugs at issue in carrying out death sentences. The statutory provision upon which the court of appeals relied, 21 U.S.C. 331(k), prohibits the "misbranding" of drugs while they are "held for sale." This provision simply cannot have been intended by Congress to reach the forcible administration of a lethal injection to a person lawfully condemned to death. /9/ See App., infra, 54a-58a (Scalia, J., dissenting); cf. United States v. Evers, 643 F.2d 1043 (5th Cir. 1981). The peculiar nature of the court of appeals' statutory construction is highlighted by the fact that Section 331(k) applies equally to "drug(s)" and "device(s)" and the fact that the statutory definition of a "device" seems clearly to encompass many of the paraphernalia traditionally used for executions, such as the gallows and the electric chair. 21 U.S.C. 321(h). /10/ Congress may not have contemplated executions by lethal injection when it enacted the FDCA in 1938, but it certainly was familiar with these "devices." We are aware of no evidence, and the court below cited none, indicating that Congress intended to empower the FDA to regulate the use of such devices. Second, even if the FDCA could somehow be stretched to reach the adminstration of lethal injections for purposes of capital punishment, the FDA had sound reasons for declining to intervene. Regulating the method of capital punishment used by the states, whether or not technically within the scope of the FDCA, is far removed from the FDA'S central responsibilities. Surely the FDA acted reasonably in conserving its limited enforcement resources for matters more closely related to its principal mission. The FDA'S decision also was based upon a proper consideration for the principles of federalism. The FDA justifiedly expressed reluctance to interfere with the states' administration of lethal injection laws, "which are duly authorized statutory enactments in furtherance of proper State functions" (App., infra, 85a). Enacting laws to prevent and punish crime is among the most important powers of the states, and in prescribing lethal injection as the method of execution, the states, acted within federal constitutional limits. The FDA was reasonable in deferring to the states' authority in this field. Finally, the FDA concluded (App., infra, 85a) that state lethal injection laws did not pose a "serious danger to the public health." The court of appeals disagreed (id. at 5a), asserting that there was "a substantial threat of torturous pain to persons being executed." However, not only is the factual basis for the court's conclusion dubious (see id at 51a-52a and n.5), but the court appears entirely to have missed the point. The proper inquiry is not whether death by lethal injection involves pain but whether it involves more pain than death by alternative methods of execution, such as the electric chair, the firing squad, or the gas chamber. As Judge Scalia put it (id. at 51a), "it is not a matter of pain versus no pain, but rather pain of one sort substituted for pain of another -- and in all likelihood substitution of a lesser pain, since that is the principal purpose of the lethal injection statutes." Such comparisons were made by the legislatures that enacted the lethal injection statutes. The FDA acted responsibly in declining to review their determinations on this unique subject. 3. a. If not reversed, the court of appeals' decision will have extremely harmful practical consequences. The FDA will be compelled to intervene in a highly controversial area far removed from its proper responsibilities, at the expense of performing its intended mission of protecting the consuming public from dangerous and misbranded drugs. Furthermore, the decision below is likely to interfere with state enforcement of capital punishment statutes that satisfy Eighth Amendment standards. As noted, the court of appeals held that the "misbranding" provision of the FDCA (21 U.S.C. 331(k)) prohibits the use, in carrying out capital punishment, of drugs that have been approved for other purposes but not for the purpose of causing death. The court also effectively held that the FDA must take action to prevent this statutory "violation." /11/ Consequently, at a minimum, the decision below will prevent executions by lethal injection until a manufacturer or other party seeks FDA approval for use of the drugs in executions and demonstrates to the FDA that they are "safe and effective" in causing death (21 U.S.C. 355(a)). Moreover, it is doubtful whether any manufacturer or other firm will seek such approval in view of the expense involved, the organized opposition to capital punishment, and the very small quantities of drugs that would be sold for this new use. Thus, the practical effect of the court of appeals' decision might well be to prevent executions by lethal injection altogether. In the long run, the court of appeals' decision may have an ironic effect. States have recently enacted statutes prescribing lethal injection as the method of carrying out death sentences precisely because that is thought to be the least painful method available. If the court of appeals' decision is allowed to stand, it may compel the states to resort to older and potentially more painful methods. b. The court of appeals' holding concerning judicial review of administrative enforcement decisions threatens judicial interference with one of the executive branch's core responsibilities. The effective functioning of administrative agencies would be seriously impaired if courts could freely second-guess such decisions. In deciding how to employ their limited enforcement resources, agenices generally concentrate on those efforts that are most needed and offer the greatest chances of success. Such choices are necessarily based in large measure on policy considerations and discretion. Thus, judicial review in this area will almost certainly result in the substitution of the preferences of the judicial branch for those of the executive. See App., infra, 39a (Scalia, J., dissenting). This alteration of the separation of powers deserves review by this Court. CONCLUSION The petition for a writ of certiorari should be granted.

When necessary the (FDA) will not hesitate to take whatever action is warranted to protect the public. /3/ Although the court of appeals acknowledged that "the state may take the life of a person as punishment" and that the "FDA is not responsible for the execution of these prisoners," the court observed that the "FDA'S impermissible refusal to exercise enforcement discretion over the use of drugs for lethal injection * * * may also implicate the Eighth Amdnement's prohibition of cruel and unusual punishment." App., infra, 37a, 38a. /4/ Judges Wilkey, Ginsburg, Bork, Scalia, and Starr voted to grant rehearing en banc. Judges Wright, Tamm, Wald, Mikva, and Robinson voted against rehearing en banc. Judge Edwards abstained. /5/ In addition, the Court refused O'Bryan's request for an order requiring the FDA to seize the drugs intended for use in his execution (O'Bryan v. Heckler, No. A-791 (Mar. 30, 1984)). Earlier that day, the United States District Court for the District of Columbia had entered such an order (Civ. No. 84-996), but the court of appeals had vacated it (No. 84-996) in light of the stay entered by the Chief Justice in this case (No. A-761) (Mar. 21, 1984). /6/ The court of appeals suggested (App., infra, 26a n.29), that Congress intended for the courts to review the FDA'S enforcement decisions because the "FDCA'S prohibitions are phrased in mandatory terms. See, e.g., 21 U.S.C. 333(a) (any person who violates Section 331 'shall' be imprisoned or fined) * * * ." However, virtually every law prescribing the penalty for a federal crime is couched in precisely the same language. See, e.g., 18 U.S.C. 371 (anyone convicted of conspiracy "shall" be imprisoned not more than five years or fined not more than $10,000). By the court of appeals' reasoning, Congress must have intended to empower the courts to review federal prosecutors' decisions concerning the bringing of charges under all of these statutes. But see United States v. Nixon, 418 U.S. 683, 693 (1974). We note in this regard that nothing in the court of appeals' decision limits the court's holding to administrative -- as opposed to criminal -- enforcement decisions. Indeed, plaintiffs in this case sought the initiation of criminal proceedings against state correctional officials and others (see App., infra, 6a). /7/ Dunlop v. Bachowski, 421 U.S. 560 (1975), upon which the court of appeals relied extensively (App., infra, 18a and n.22, 21a-23a and nn. 25-26), involved such special circumstances. In that case, a defeated candidate for union office sought to compel the Secretary of Labor to bring suit under provisions of the Labor-Management Reporting and Disclosure Act (LMRDA), 29 U.S.C. 482(a) and (b), to have the election set aside. In holding that the Secretary's refusal to bring suit was reviewable, this Court did not discuss the Secretary's contention that the decision was an unreviewable exercise of prosecutorial discretion, but instead merely expressed agreement (421 U.S. at 567 n.7) with the court of appeals' treatment of the issue. See Bachowski v. Brennan, 502 F.2d 79 (3d Cir. 1974). The court of appeals noted that the exercise of enforcement discretion is generally unreviewable (see 502 F.2d at 86-87), but distinguished the case on three gounds. First, the court concluded (id at 87), based on the legislative history of the LMRDA, that in empowering the Secretary to bring suit to set aside an election, Congress intended the Secretary to act on behalf of aggrieved union members rather than merely on behalf of the public. Second, it noted (id. at 87-88) that union members have no remedy if the Secretary does not act. And third, the court observed (id. at 88) that the Secretary's discretion was restricted by statute because he was required to bring suit whenever there was probable cause to believe that there had been a violation affecting the outcome of the election and no settlement was reached. None of these factors applies here. FDA enforcement is intended to protect the general public, not to redress individual wrongs; persons such as plaintiffs in this case can challenge their sentences in a variety of other ways; and under the FDCA, the FDA has the traditional broad scope of enforcement discretion. /8/ Legal Status of Approved Labeling for Prescription Drugs: Prescribing for Uses Unapproved by the Food and Drug Administration, 37 Fed. Reg. 16503 (1972). /9/ In concluding that the FDA possessed the authority to grant respondents' requested relief, the court of appeals repeatedly referred to the FDA'S actions regarding drugs used to destroy animals and drugs administered to prisoners participating in research projects. App., infra, 11a-12a, 31a, 32a. These situations, however, are clearly distinguishable. In United States v. Beuthanasia-D Regular, (1979 Transfer Binder) Food, Drug, Cosm. L. Rep. (CCH) Paragraph 38,265 (D. Neb.), upon which the court of appeals relied (App., infra, 12a), the FDA did not assert authority over the use of drugs to destroy animals. That case instead involved the marketing of such drugs. Thus, the case was of the type in which FDA normally assumes jurisdiction -- the marketing and promoting by a manufacturer of a drug for a purpose that has not been subject to pre-marketing approval. Moreover, the FDA'S statutory authority with respect to animal drugs differs from its authority with respect to human drugs. See 21 U.S.C. 360b(a)(1). The FDA also has special statutory authority to regulate the use of drugs in research projects (see 21 U.S.C. 355(i), 357(d), 360j(g), participation in which in any event is voluntary. The regulations to which the court of appeals referred (App., infra, 12a n.17) implement such special statutory provisions and therefore have no relevance here. /10/ 21 U.S.C. 321(h) defines a "device" to include (A)n instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including any component, part, or accessory, which is -- *** (3) intended to affect the structure or any function of the body of man or other animals, and which does not achieve any of its principal intended purposes through chemical action within or on the body of man or other animals and which is not dependent upon being metabolized for the achievement of any of its principal intended purposes. /11/ The court of appeals remanded for the district court to determine whether the FDA'S reasons for refusing to initiate enforcement action were sufficient (see App., infra, 31a). However, the court of appeals' opinion left no doubt that in its view all of the FDA'S proferred justifications were unsound (id. at 30a-35a). APPENDIX
