A general court-martial found petitioner Loving, an Army private, guilty of both premeditated murder and felony murder under Article 118 of the Uniform Code of Military Justice (UCMJ), 10 U. S. C. Section(s) 918(1), (4). Finding three aggravating factors-(1) that the premeditated murder was committed during a robbery, Rule for Courts-Martial (RCM) the premeditated murder, had committed a second murder, also proved at his single trial, RCM 1004(c)(7)(J)-the court-martial sentenced Loving to death. The commander who convened the court-martial approved the findings and sentence. The United States Army Court of Military Review and the United States Court of Appeals for the Armed Forces affirmed, rejecting Loving's attack on the promulgation by Executive Order of the aggravating factors in RCM 1004. He contends that the Eighth Amendment and the separation-of-powers doctrine require that Congress, not the President, make the fundamental policy determination respecting the factors that warrant the death penalty.
1. On the assumption that Furman v. Georgia, 408 U.S. 238 , and subsequent cases apply to this crime and sentence, the Constitution requires the aggravating factors that Loving challenges. Under the Eighth Amendment, the military capital sentencing scheme must genuinely narrow the class of persons eligible for the death penalty and must reasonably justify the imposition of a more severe sentence on the accused compared to others found guilty of murder, see, e.g., Lowenfield v. Phelps, 484 U.S. 231, 244 . That narrowing is not achieved in the statute. Article 118 authorizes the death penalty for but two of the four types of murder therein specified, premeditated and felony murder, Section(s) 918(1), (4), whereas intentional murder without premeditation and murder resulting from wanton and dangerous conduct are not punishable by death, Section(s) 918(2), (3). Moreover, Article 118(4) by its terms permits the death penalty for felony murder even if the accused had no intent to kill and did not do the killing himself. Because the Eighth Amendment does not permit death to be imposed in those circumstances, Enmund v. Florida, 458 U.S. 782, 801 , additional aggravating factors establishing a higher culpability are necessary to Article 118's constitutional validity, see, e.g., Lowenfield, supra, at 244. Pp. 5-6.
2. The President's prescription of the challenged aggravating factors did not violate the separation-of-powers principle. Pp. 6-25.
(a) The fundamental precept of the delegation doctrine, a strand of this Court's separation-of-powers jurisprudence, is that the lawmaking function belongs to Congress, U. S. Const., Art. I, Section(s) 1, and may not be conveyed to another branch or entity, Field v. Clark, 143 U. S. 649, 692. This principle does not mean, however, that only Congress can make a rule of prospective force. Although it may not delegate the power to make the law, which necessarily involves discretion as to what the law shall be, Congress may delegate to others the authority or discretion to execute the law under and in pursuance of its terms. Id., at 693-694. Pp. 6-10.
(b) The Court rejects Loving's argument that Congress lacks power to delegate to the President the authority to prescribe aggravating factors in capital murder cases. An analysis of English constitutional history and of the historical necessities and events that instructed the Framers demonstrates that U. S. Const., Art. I, Section(s) 8, cl. 14-which empowers Congress "[t]o make Rules for the Government and Regulation of the land and naval forces"-does not grant an exclusive, nondelegable power to determine military punishments, but gives Congress such flexibility to exercise or share power as the times might demand. And it would be contrary to the respect owed the President as Commander in Chief to hold that he may not be given wide discretion and authority. Thus, in the circumstances presented here, Congress may delegate authority to the President to define the aggravating factors that permit imposition of a statutory penalty, with the regulations providing the narrowing of the death-eligible class that the Eighth Amendment requires. Pp. 10-19.
delegate to the President the authority to prescribe aggravating factors, Congress did not do so by implicit or explicit action in this instance. In fact, Congress exercised that power of delegation in 1950, when it enacted Articles 18, 56, and 36(a) of the UCMJ, 10 U. S. C. Section(s) 818 (A court-martial "may, under such limitations as the President may prescribe, adjudge any punishment not forbidden by [the UCMJ], including the penalty of death when specifically authorized"), 856 ("The punishment which a court-martial may direct . . . may not exceed such limits as the President may prescribe for that offense"), and 836(a) (which empowers the President to make procedural rules for courtsmartial, and was identified by Congress in 1985 as a source of Presidential authority to provide capital aggravating factors). Together, these Articles give clear authority to the President to promulgate RCM 1004. Pp. 20-22.
(d) Loving's final assertion-that even if Articles 18, 56, and 36 can be construed as delegations, they lack an intelligible principle to guide the President's discretion-is also rejected. Had the delegations here called for the exercise of judgment or discretion that lies beyond the President's traditional authority, this argument might have more weight. However, because the President's duties as Commander in Chief require him to take responsible and continuing action to superintend the military, including the courts-martial, the delegated duty to prescribe aggravating factors for capital cases is interlinked with duties already assigned to him by the Constitution's express terms. The same limitations on delegation do not apply where the entity exercising the delegated authority possesses independent authority over the subject matter. See, e.g., United States v. Mazurie, 419 U.S. 544, 556 -557. Pp. 22-25.

[End of Syllabus]
After a trial, an eight-member general court-martial found Loving guilty of, among other offenses, premeditated murder and felony murder under Article 118 of the Uniform Code of Military Justice (UCMJ), 10 U. S. C. Section(s) 918(1), (4). In the sentencing phase of the trial, the court-martial found three aggravating factors: (1) that the premeditated murder of the second driver was committed during the course of a robbery, Rule for Courts-Martial (RCM) 1004(c)(7)(B); (2) that Loving acted as the triggerman in the felony murder of the first driver, premeditated murder, had committed a second murder, also proven at the death. The commander who convened the court-martial approved the findings and sentence. Cf. 10 U. S. C. Section(s) 860. The United States Army Court of Military Review and the United States Court of Appeals for the Armed Forces (formerly the United States Court of Military Appeals (CMA)) affirmed, relying on United States v. Curtis, 32 M. J. 252 (CMA), cert. denied, 502 U.S. 952 (1991), to reject Loving's claims that the President lacked authority to promulgate the aggravating factors that enabled the court-martial to sentence him to death. We granted certiorari. 515 U. S. ___ (1995).
Over the next two centuries, Congress expanded court-martial jurisdiction. In 1863, concerned that civil courts could not function in all places during hostilities, Congress granted courts-martial jurisdiction of common-law capital crimes and the authority to impose the death penalty in wartime. Act of Mar. 3, 1863, Section(s) 30, 12 Stat. 736, Rev. Stat. Section(s) 1342, Art. 58 (1875); Coleman v. Tennessee, 97 U. S. 509, 514 (1879). In 1916, Congress granted to the military courts a general jurisdiction over common-law felonies committed by service members, except for murder and rape committed within the continental United States during peacetime. Articles of War of 1916, ch. 418, Section(s) 3, Arts. 92-93, 39 Stat. 664. Persons accused of the latter two crimes were to be turned over to the civilian authorities. Art. 74, 39 Stat. 662. In 1950, with the passage of the UCMJ, Congress lifted even this restriction. Article 118 of the UCMJ describes four types of murder subject to court-martial jurisdiction, two of which are punishable by death:
The President responded to Matthews in 1984 with an Executive Order promulgating RCM 1004. In conformity with 10 U. S. C. Section(s) 852(a)(1), the Rule, as amended, requires a unanimous finding that the accused was guilty of a capital offense before a death sentence may be imposed, RCM 1004(a)(2). The Rule also requires unanimous findings (1) that at least one aggravating factor is present and (2) that any extenuating or mitigating circumstances are substantially outweighed by any admissible aggravating circumstances, 1004(b). RCM 1004(c) enumerates 11 categories of aggravating factors sufficient for imposition of the death penalty. The Rule also provides that the accused is to have "broad latitude to present evidence in extenuation and mitigation," 1004(b)(3), and is entitled to have the members of the court-martial instructed to consider all such evidence before deciding upon a death sentence, 1004(b)(6).
This is the scheme Loving attacks as unconstitutional. He contends that the Eighth Amendment and the doctrine of separation of powers require that Congress, and not the President, make the fundamental policy determination respecting the factors that warrant the death penalty.
Although the Government suggests the contrary, Brief for United States 11, n. 6, we agree with Loving, on the assumption that Furman applies to this case, that aggravating factors are necessary to the constitutional validity of the military capital-punishment scheme as now enacted. Article 118 authorizes the death penalty for but two of the four types of murder specified: premeditated and felony murder are punishable by death, 10 U. S. C. Section(s) 918(1), (4), whereas intentional murder without premeditation and murder resulting from wanton and dangerous conduct are not, Section(s) 918(2), (3). The statute's selection of the two types of murder for the death penalty, however, does not narrow the death-eligible class in a way consistent with our cases. Article 118(4) by its terms permits death to be imposed for felony murder even if the accused had no intent to kill and even if he did not do the killing himself. The Eighth Amendment does not permit the death penalty to be imposed in those circumstances. Enmund v. Florida, 458 U.S. 782, 801 (1982). As a result, additional aggravating factors establishing a higher culpability are necessary to save Article 118. We turn to the question whether it violated the principle of separation of powers for the President to prescribe the aggravating factors required by the Eighth Amendment.
Deterrence of arbitrary or tyrannical rule is not the sole reason for dispersing the federal power among three branches, however. By allocating specific powers and responsibilities to a branch fitted to the task, the Framers created a National Government that is both effective and accountable. Article I's precise rules of representation, member qualifications, bicameralism, and voting procedure make Congress the branch most capable of responsive and deliberative lawmaking. See Chadha, supra, at 951. Ill suited to that task are the Presidency, designed for the prompt and faithful execution of the laws and its own legitimate powers, and the Judiciary, a branch with tenure and authority independent of direct electoral control. The clear assignment of power to a branch, furthermore, allows the citizen to know who may be called to answer for making, or not making, those delicate and necessary decisions essential to governance.
Another strand of our separation-of-powers jurisprudence, the delegation doctrine, has developed to prevent Congress from forsaking its duties. Loving invokes this doctrine to question the authority of the President to promulgate RCM 1004. The fundamental precept of the delegation doctrine is that the lawmaking function belongs to Congress, U. S. Const., Art. I, Section(s) 1, and may not be conveyed to another branch or entity. Field v. Clark, 143 U. S. 649, 692 (1892). This principle does not mean, however, that only Congress can make a rule of prospective force. To burden Congress with all federal rulemaking would divert that branch from more pressing issues, and defeat the Framers' design of a workable National Government. Thomas Jefferson observed, "Nothing is so embarrassing nor so mischievous in a great assembly as the details of execution." 5 Works of Thomas Jefferson 319 (P. Ford ed. 1904) (Letter to E. Carrington, Aug. 4, 1787). See also A. L. A. Schechter Poultry Corp. v. United States, 295 U. S. 495, 529-530 (1935) (recognizing "the necessity of adapting legislation to complex conditions involving a host of details with which the national legislature cannot deal directly"). This Court established long ago that Congress must be permitted to delegate to others at least some authority that it could exercise itself. Wayman v. Southard, 10 Wheat. 1, 42 (1825).
We have undertaken before, in resolving other issues, the difficult task of interpreting Clause 14 by drawing upon English constitutional history. See, e.g., Reid, supra, at 23-30; O'Callahan v. Parker, 395 U.S. 258, 268 -272 (1969) (determining that courts-martial only had jurisdiction of service-connected crimes); Solorio v. United States, 483 U.S. 435, 442 -446 (1987) (overruling O'Callahan and taking issue with its historical analysis). Doing so here, we find that, although there is a grain of truth in Loving's historical arguments, the struggle of Parliament to control military tribunals and the lessons the Framers drew from it are more complex than he suggests. The history does not require us to read Clause 14 as granting to Congress an exclusive, nondelegable power to determine military punishments. If anything, it appears that England found security in divided authority, with Parliament at times ceding to the Crown the task of fixing military punishments. From the English experience the Framers understood the necessity of balancing efficient military discipline, popular control of a standing army, and the rights of soldiers; they perceived the risks inherent in assigning the task to one part of the government to the exclusion of another; and they knew the resulting parliamentary practice of delegation. The Framers' choice in Clause 14 was to give Congress the same flexibility to exercise or share power as times might demand.
In England after the Norman Conquest, military justice was a matter of royal prerogative. The rudiments of law in English military justice can first be seen in the written orders issued by the King for various expeditions. Winthrop 17-18. For example, in 1190 Richard I issued an ordinance outlining six offenses to which the crusaders would be subject, including two punishable by death: "Whoever shall slay a man on ship-board, he shall be bound to the dead man and thrown into the sea. If he shall slay him on land he shall be bound to the dead man and buried in the earth." Ordinance of Richard I-A.D. 1190, reprinted in id., at 903. The first comprehensive articles of war were those declared by Richard II at Durham in 1385 and Henry V at Mantes in 1419, which decreed capital offenses that not only served military discipline but also protected foreign noncombatants from the ravages of war. T. Meron, Henry's Wars and Shakespeare's Laws: Perspectives on the Law of War in the Later Middle Ages 91-93 (1993). Articles of War, sometimes issued by military commanders acting under royal commission in the ensuing centuries, Winthrop 19, were not fixed codes, at least through the 17th century; rather, "each war, each expedition, had its own edict," which lost force after the cessation of hostilities and the disbanding of the army that had been formed. J. Pipon & J. Collier, Manual of Military Law 14 (3d rev. ed. 1863).
Thus, royal ordinances governed the conduct of war, but the common law did not countenance the enforcement of military law in times of peace "when the king's courts [were] open for all persons to receive justice according to the laws of the land." 1 Blackstone's Commentaries *413. See also M. Hale, History of the Common Law of England 25-27 (C. Gray ed. 1971) (describing efforts of Parliament and the common law courts to limit the jurisdiction of the military Courts of the Constable and the Marshal).
The triumph of civil jurisdiction was not absolute, however. The political disorders of the 17th century ushered in periods of harsh military justice, with soldiers and at times civilian rebels punished, even put to death, under the summary decrees of courts-martial. See C. Clode, Administration of Justice Under Military and Martial Law 20-42 (1872) (hereinafter Clode). Cf. Petition of Right of 1627, 3 Car. I, ch. 1 (protesting court-martial abuses). Military justice was brought under the rule of parliamentary law in 1689, when William and Mary accepted the Bill of Rights requiring Parliament's consent to the raising and keeping of armies. In the Mutiny Act of 1689, Parliament declared the general principle that "noe Man may be forejudged of Life or Limbe or subjected to any kinde of punishment by Martiall Law or in any other manner then by the Judgment of his Peeres and according to the knowne and Established Laws of this Realme," but decreed that "Soldiers who shall Mutiny or stirr up Sedition or shall desert Their Majestyes Service be brought to a more Exemplary and speedy Punishment than the usuall Forms of Law will allow," and "shall suffer Death or such other Punishment as by a Court-Martiall shall be Inflicted." 1 Wm. Mary, ch. 5.
In one sense, as Loving wants to suggest, the Mutiny Act was a sparing exercise of parliamentary authority, since only the most serious domestic offenses of soldiers were made capital, and the militia was exempted. See Solorio, supra, at 442. He misunderstands the Mutiny Act of 1689, however, in arguing that it bespeaks a special solicitude for the rights of soldiers and a desire of Parliament to exclude Executive power over military capital punishment.
The Mutiny Act, as its name suggests, came on the heels of the mutiny of Scottish troops loyal to James II. 3 Macaulay 45-49. The mutiny occurred at a watershed time. Menaced by great continental powers, England had come to a grudging recognition that a standing army, long decried as an instrument of despotism, had to be maintained on its soil. The mutiny cast in high relief the dangers to the polity of a standing army turned bad. Macaulay describes the sentiment of the time:
Popular suspicion of the standing army persisted, 5 Macaulay 253-273, 393, and Parliament authorized the Mutiny Acts only for periods of six months and then a year, 3 id., at 51-53. But renewed they were time and again, and Parliament would alter the power of courts-martial to impose the death penalty for peacetime offenses throughout the next century. It withdrew the power altogether in 1713, 12 Anne, ch. 13, Section(s) 1, only to regret the absence of the penalty during the rebellion of 1715, Clode 49. The third of the Mutiny Acts of 1715 subjected the soldier to capital punishment for a wide array of peacetime offenses related to political disorder and troop discipline. Id., at 50. And, for a short time in the 18th century, Parliament allowed the Crown to invest courts-martial with a general criminal jurisdiction over soldiers even at home, placing no substantive limit on the penalties that could be imposed; until 1718, that jurisdiction was superior to civil courts. Id., at 52-53. The propriety of that general jurisdiction within the kingdom was questioned, and the jurisdiction was withdrawn in 1749. Id., at 53. Nevertheless, even as it continued to adjust the scope of military jurisdiction at home, Parliament entrusted broad powers to the Crown to define and punish military crimes abroad. In 1713, it gave statutory sanction to the Crown's longstanding practice of issuing Articles of War without limiting the kind of punishments that might be imposed; and, in the same Act, it delegated the power to "erect and constitute Courts Martial with Power to try hear and determine any Crime or Offence by such Articles of War and inflict Penalties by Sentence or Judgement in any of Her Majesties Dominions beyond the Seas or elsewhere beyond the Seas (except in the Kingdom of Ireland) . . . as might have been done by Her Majesties Authority beyond the Seas in Time of War." 12 Anne, ch. 13, Section(s) 43; Winthrop 20. Cf. Duke & Vogel, supra, at 444 (noting that Parliament in 1803 gave statutory authority to the Crown to promulgate Articles of War applicable to troops stationed in England as well). See Solorio, 483 U.S., at 442 (discussing a provision in the British Articles of War of 1774 providing court-martial jurisdiction of civilian offenses by soldiers).
As Loving contends, and as we have explained elsewhere, the Framers well knew this history, and had encountered firsthand the abuses of military law in the colonies. See Reid, 354 U.S., at 27 -28. As many were themselves veterans of the Revolutionary War, however, they also knew the imperatives of military discipline. What they distrusted were not courts-martial per se, but military justice dispensed by a commander unchecked by the civil power in proceedings so summary as to be lawless. The latter was the evil that caused Blackstone to declare that "martial law" -- by which he, not observing the modern distinction between military and martial law, meant decrees of courts-martial disciplining soldiers in wartime -- "is built upon no settled principles, but is entirely arbitrary in its decisions, [and] is, as Sir Matthew Hale observes, in truth and reality no law, but something indulged rather than allowed as a law." 1 Blackstone's Commentaries *413. See also Hale, History of the Common Law of England, at 26-27; Clode 21 (military law in early seventeenth century England amounted to "the arbitrary right to punish or destroy, without legal trial, any assumed delinquent"). The partial security Englishmen won against such abuse in 1689 was to give Parliament, preeminent guardian of the British constitution, primacy in matters of military law. This fact does not suggest, however, that a legislature's power must be exclusive. It was for Parliament, as it did in the various Mutiny Acts, to designate as the times required what peacetime offenses by soldiers deserved the punishment of death; and it was for Parliament, as it did in 1713, to delegate the authority to define wartime offenses and devise their punishments, including death. The Crown received the delegated power and the concomitant responsibility for its prudent exercise. The lesson from the English constitutional experience was that Parliament must have the primary power to regulate the armed forces and to determine the punishments that could be imposed upon soldiers by courts-martial. That was not inconsistent, however, with the further power to divide authority between it and the Crown as conditions might warrant.
Far from attempting to replicate the English system, of course, the Framers separated the powers of the Federal Government into three branches to avoid dangers they thought latent or inevitable in the parliamentary structure. The historical necessities and events of the English constitutional experience, though, were familiar to them and inform our understanding of the purpose and meaning of constitutional provisions. As we have observed before, with this experience to consult they elected not to "freeze court-martial usage at a particular time" for all ages following, Solorio, 483 U.S., at 446 , nor did they deprive Congress of the services of the Executive in establishing rules for the governance of the military, including rules for capital punishment. In the words of Alexander Hamilton, the power to regulate the armed forces, like other powers related to the common defense, was given to Congress
Under Clause 14, Congress, like Parliament, exercises a power of precedence over, not exclusion of, Executive authority. Cf. United States v. Eliason, 16 Pet. 291, 301 (1842) ("The power of the executive to establish rules and regulations for the government of the army, is undoubted"). This power is no less plenary than other Article I powers, Solorio, supra, at 441, and we discern no reasons why Congress should have less capacity to make measured and appropriate delegations of this power than of any other, see Skinner v. Mid-America Pipeline Co., 490 U.S. 212, 220 -221 (1989) (Congress may delegate authority under the taxing power); cf. Lichter v. United States, 334 U.S. 742, 778 (1948) (general rule is that "[a] constitutional power implies a power of delegation of authority under it sufficient to effect its purposes") (emphasis deleted). Indeed, it would be contrary to precedent and tradition for us to impose a special limitation on this particular Article I power, for we give Congress the highest deference in ordering military affairs. Rostker v. Goldberg, 453 U.S. 57, 64 -65 (1981). And it would be contrary to the respect owed the President as Commander in Chief to hold that he may not be given wide discretion and authority. We decline to import into Clause 14 a restrictive nondelegation principle that the Framers left out.
There is no absolute rule, furthermore, against Congress' delegation of authority to define criminal punishments. We have upheld delegations whereby the Executive or an independent agency defines by regulation what conduct will be criminal, so long as Congress makes the violation of regulations a criminal offense and fixes the punishment, and the regulations "confin[e] themselves within the field covered by the statute." United States v. Grimaud, 220 U. S. 506, 518 (1911). See also Touby v. United States, 500 U.S. 160 (1991). The exercise of a delegated authority to define crimes may be sufficient in certain circumstances to supply the notice to defendants the Constitution requires. See M. Kraus & Bros., Inc. v. United States, 327 U.S. 614, 622 (1946). In the circumstances presented here, so too may Congress delegate authority to the President to define the aggravating factors that permit imposition of a statutory penalty, with the regulations providing the narrowing of the death-eligible class that the Eighth Amendment requires.
In 1950, Congress confronted the problem of what criminal jurisdiction would be appropriate for armed forces of colossal size, stationed on bases that in many instances were small societies unto themselves. Congress, confident in the procedural protections of the UCMJ, gave to courts-martial jurisdiction of the crime of murder. Cf. Solorio, supra, at 450-451 (Congress may extend court-martial jurisdiction to any criminal offense committed by a service member during his period of service). It further declared the law that service members who commit premeditated and felony murder may be sentenced to death by a court-martial. There is nothing in the constitutional scheme or our traditions to prohibit Congress from delegating the prudent and proper implementation of the capital murder statute to the President acting as Commander in Chief.
There is yet a third provision of the UCMJ indicative of congressional intent to delegate this authority to the President. Article 36 of the UCMJ, which gives the President the power to make procedural rules for courts-martial, provides:
Loving points out that the three Articles were enacted as part of the UCMJ in 1950, well before the need for eliminating absolute discretion in capital sentencing was established in Furman v. Georgia, 408 U.S. 238 (1972), and the cases that followed. (Slight amendments to the Articles have been made since but are not relevant here.) In 1950, he argues, Congress could not have understood that it was giving the President the authority to bring an otherwise invalid capital murder statute in line with Eighth Amendment strictures. Perhaps so, but Furman did not somehow undo the prior delegation. What would have been an act of leniency by the President prior to Furman may have become a constitutional necessity thereafter, see supra, at 5-6, but the fact remains the power to prescribe aggravating circumstances has resided with the President since 1950.
In United States v. Curtis, the Court of Military Appeals discerned a principle limiting the President's discretion to define aggravating factors for capital crimes in Article 36: namely, the directive that regulations the President prescribes must "apply the principles of law . . . generally recognized in the trial of criminal cases in the United States district courts, but which may not be contrary to or inconsistent with this chapter," 10 U. S. C. Section(s) 836(a). We think, however, that the question to be asked is not whether there was any explicit principle telling the President how to select aggravating factors, but whether any such guidance was needed, given the nature of the delegation and the officer who is to exercise the delegated authority. First, the delegation is set within boundaries the President may not exceed. Second, the delegation here was to the President in his role as Commander in Chief. Perhaps more explicit guidance as to how to select aggravating factors would be necessary if delegation were made to a newly created entity without independent authority in the area. Cf. Mistretta, 488 U.S., at 374 -379 (upholding delegation to the United States Sentencing Commission because of detailed congressional directives channeling agency discretion). The President's duties as Commander in Chief, however, require him to take responsible and continuing action to superintend the military, including the courts-martial. The delegated duty, then, is interlinked with duties already assigned to the President by express terms of the Constitution, and the same limitations on delegation do not apply "where the entity exercising the delegated authority itself possesses independent authority over the subject matter," United States v. Mazurie, 419 U.S. 544, 556 -557 (1975). See also United States v. Curtiss-Wright Export Corp., 299 U. S. 304, 319-322 (1936). Cf. Swaim v. United States, 165 U. S. 553, 557-558 (1897) (President has inherent authority to convene courts-martial). Like the Court of Military Appeals, Curtis, 32 M. J., at 263, n. 9, we need not decide whether the President would have inherent power as Commander in Chief to prescribe aggravating factors in capital cases. Once delegated that power by Congress, the President, acting in his constitutional office of Commander in Chief, had undoubted competency to prescribe those factors without further guidance. "The military constitutes a specialized community governed by a separate discipline from that of the civilian," Orloff v. Willoughby, 345 U.S. 83, 94 (1953), and the President can be entrusted to determine what limitations and conditions on punishments are best suited to preserve that special discipline.
It is hard to deem lawless a delegation giving the President broad discretion to prescribe rules on this subject. From the early days of the Republic, the President has had congressional authorization to intervene in cases where courts-martial decreed death. American Articles of War of 1806, Art. 65, reprinted in Winthrop 976, 982. It would be contradictory to say that Congress cannot further empower him to limit by prospective regulation the circumstances in which courtsmartial can impose a death sentence. Specific authority to make rules for the limitation of capital punishment contributes more towards principled and uniform military sentencing regimes than does case-by-case intervention, and it provides greater opportunity for congressional oversight and revision.
Separation-of-powers principles are vindicated, not disserved, by measured cooperation between the two political branches of the Government, each contributing to a lawful objective through its own processes. The delegation to the President as Commander in Chief of the authority to prescribe aggravating factors was in all respects consistent with these precepts, and the promulgation of RCM 1004 was well within the delegated authority. Loving's sentence was lawful, and the judgment of the Court of Appeals of the Armed Forces is affirmed.
It is so ordered.
Justice Stevens, with whom Justice Souter, Justice Ginsburg, and Justice Breyer join, concurring.
As Justice Scalia correctly points out, petitioner has not challenged the power of the tribunal to try him for a capital offense. Post, at 1. It is important to add to this observation that petitioner's first victim was a member of the Armed Forces on active duty and that the second was a retired serviceman who gave petitioner a ride from the barracks on the same night as the first killing. Brief for United States 5. On these facts, this does not appear to be a case in which petitioner could appropriately have raised the question whether the holding in Solorio v. United States, 483 U.S. 435 (1987), should be extended to reach the imposition of the death penalty for an offense that did not have the "service connection" required prior to the change in the law effected in that case. Id., at 451 (Stevens, J., concurring in judgment).
The question whether a "service connection" requirement should obtain in capital cases is an open one both because Solorio was not a capital case, and because Solorio's review of the historical materials would seem to undermine any contention that a military tribunal's power to try capital offenses must be as broad as its power to try non-capital ones. See id., at 442-446. Moreover, the question is a substantial one because, when the punishment may be death, there are particular reasons to ensure that the men and women of the Armed Forces do not by reason of serving their country receive less protection than the Constitution provides for civilians.
As a consequence of my conclusion that the "service connection" requirement has been satisfied here, I join not only the Court's analysis of the delegation issue, but also its disposition of the case. By joining in the Court's opinion, however, I do not thereby accept the proposition that our decision in Solorio must be understood to apply to capital offenses. Nor do I understand the Court's decision to do so. That question, as I have explained, remains to be decided.
Justice Scalia, with whom Justice O'Connor joins, concurring in part and concurring in the judgment.
I join the Court's opinion, except that with respect to Part IV thereof I join only subparts B and C.
The discussion of English history that features so prominently in the Court's discussion of Congress's power to grant the authority at issue to the President is in my view irrelevant. To be sure, there is ample precedent in our cases for looking to the history of English courts-martial -- but not where the question is of the sort before us today. We have surveyed that history for the purpose of establishing the permissible scope of the jurisdiction of military tribunals over certain classes of defendants and offenses, see, e.g., Solorio v. United States, 483 U.S. 435, 442 -446 (1987); Lee v. Madigan, 358 U.S. 228, 232 (1959); Reid v. Covert, 354 U.S. 1, 23 -27 (1957) (plurality); see also Parker v. Levy, 417 U.S. 733, 745 (1974). This case does not present such a question. Petitioner does not assert that tradition establishes his offense to be, in its nature, beyond the jurisdiction of military courts, or that courts-martial are historically incapable of adjudicating capital offenses. His arguments are altogether different: that Congress cannot authorize the President to establish "aggravating factors" designed to carry out the narrowing function that (we assume) is necessary for imposition of a capital sentence; and that, even if Congress can give the President authority to perform this function, such authorization has not been effected by the statutes upon which the Government relies.
I do not see how consideration of those arguments profits from analysis of the historical sharing of power between Parliament and the English throne. William and Mary's acceptance of the Bill of Rights, and Parliament's enactment of the Mutiny Act of 1689, see ante, at 13-16, are presumably significant occurrences for students of the unwritten English constitution. Our written Constitution does not require us to trace out that history; it provides, in straightforward fashion, that "The Congress shall have Power . . . To make Rules for the Government and Regulation of the land and naval forces," U. S. Const., Art. I, Section(s) 8, cl. 14, and as the Court notes, see ante, at 18, it does not set forth any special limitation on Congress's assigning to the President the task of implementing the laws enacted pursuant to that power. And it would be extraordinary simply to infer such a special limitation upon tasks given to the President as Commander in Chief, where his inherent powers are clearly extensive.
In drafting the Constitution, the Framers were not seeking to replicate in America the government of England; indeed, they set their plan of government out in writing in part to make clear the ways in which it was different from the one it replaced. The Court acknowledges this, see ante, at 17, but nonetheless goes on to treat the form of English government as relevant to determining the limitations upon Clause 14's grant of power to Congress. I would leave this historical discussion aside. While it is true, as the Court demonstrates, that the scheme of assigned responsibility here conforms to English practices, that is so not because Clause 14 requires such conformity, but simply because what seemed like a good arrangement to Parliament has seemed like a good arrangement to Congress as well.
I have one point of definition or conceptualization, which applies to those portions of the opinion that I have joined. While it has become the practice in our opinions to refer to "unconstitutional delegations of legislative authority" versus "lawful delegations of legislative authority," in fact the latter category does not exist. Legislative power is nondelegable. Congress can no more "delegate" some of its Article I power to the Executive than it could "delegate" some to one of its committees. What Congress does is to assign responsibilities to the Executive; and when the Executive undertakes those assigned responsibilities it acts, not as the "delegate" of Congress, but as the agent of the People. At some point the responsibilities assigned can become so extensive and so unconstrained that Congress has in effect delegated its legislative power; but until that point of excess is reached there exists, not a "lawful" delegation, but no delegation at all.
Justice Thomas, concurring in the judgment.
It is not clear to me that the extensive rules we have developed under the Eighth Amendment for the prosecution of civilian capital cases, including the requirement of proof of aggravating factors, necessarily apply to capital prosecutions in the military, cf. Chappell v. Wallace, 462 U.S. 296, 300 -302 (1983), and this Court has never so held, see Schick v. Reed, 419 U.S. 256, 260 (1974). 1 I am therefore not certain that this case even raises a delegation question, for if Loving can constitutionally be sentenced to death without proof of aggravating factors, he surely cannot claim that the President violated the Constitution by promulgating aggravating factors that afforded more protection than that to which Loving is constitutionally entitled.
Like the majority, I conclude that the Government prevails even if we assume, without deciding, that aggravating factors are required in this context. There is abundant authority for according Congress and the President sufficient deference in the regulation of military affairs to uphold the delegation here, and I see no need to resort to our nonmilitary separation-of-powers and "delegation doctrine" cases in reaching this conclusion. I write separately to explain that by concurring in the judgment in this case, I take no position with respect to Congress' power to delegate authority or otherwise alter the traditional separation of powers outside the military context.
In light of Congress' express constitutional authority to regulate the Armed Forces, see U. S. Const., Art. I, Section(s) 8, cl. 14, and the unique nature of the military's mission, we have afforded an unparalleled degree of deference to congressional action governing the military. See Rostker v. Goldberg, 453 U.S. 57, 64 -65 (1981). "[I]t is the primary business of armies and navies to fight or be ready to fight wars should the occasion arise," United States ex rel. Toth v. Quarles, 350 U.S. 11, 17 (1955), and this Court has recognized the limits on its own competence in advancing this core national interest, see Gilligan v. Morgan, 413 U.S. 1, 10 (1973). Mindful of the factors that "differentiate military society from civilian society," we have concluded that the Constitution permits Congress "to legislate both with greater breadth and with greater flexibility when prescribing the rules by which the former shall be governed than it is when prescribing rules for the latter." Parker v. Levy, 417 U.S. 733, 756 (1974). This heightened deference extends not only to congressional action but also to executive action by the President, who by virtue of his constitutional role as Commander in Chief, see U. S. Const, Art. II, Section(s) 2, cl. 1, possesses shared authority over military discipline. See Schlesinger v. Ballard, 419 U.S. 498, 510 (1975) ("The responsibility for determining how best our Armed Forces shall attend to th[e] business [of fighting or preparing to fight wars] rests with Congress and with the President") (citations omitted). See also Brown v. Glines, 444 U.S. 348, 360 (1980) ("Both Congress and this Court have found that the special character of the military requires civilian authorities to accord military commanders some flexibility in dealing with matters that affect internal discipline and morale. In construing a statute that touches on such matters, therefore, courts must be careful not to `circumscribe the authority of military commanders to an extent never intended by Congress'") (citations omitted). Under these and many similar cases reviewing legislative and executive control of the military, the sentencing scheme at issue in this case, and the manner in which it was created, are constitutionally unassailable.
On a separate point, I agree with Justice Scalia that the majority's extended analysis of the division of authority between the English Parliament and the Crown with regard to regulation of the military, see ante, at 10-17, has no relevance to this case. It is true that we frequently consult English history and common law in attempting to determine the content of constitutional provisions, but the majority fails to cite a single separation-of-powers case in which we have relied on the structure of the English Government in attempting to understand the governmental structure erected by the Framers of the Constitution. Nor does the majority cite any historical evidence, whether from the constitutional debates, the Federalist Papers, or some other source, that demonstrates that the Framers sought to embrace, or at least actively considered, the English system of shared power over the military. If the majority pointed to some basis for conducting the inquiry that it does, I might be willing to accept its analysis. Instead, the majority repeatedly substitutes ipse dixit for historical evidence. See, e.g., ante, at 11 ("From the English experience the Framers . . . knew the . . . parliamentary practice of delegation" and "[t]he Framers' choice in Clause 14 was to give Congress the same flexibility to exercise or share power"); ante, at 16 ("the Framers well knew this history"); ante, at 17 ("The historical necessities and events of the English constitutional experience . . . were familiar to [the Framers] and inform our understanding of the purpose and meaning of constitutional provisions"). I have no doubt that the Framers were well versed in English history. But it is too simplistic for purposes of constitutional analysis to draw conclusions about the allocation of constitutional author-ity among the branches of the United States Government from mere speculation about the Framers' familiarity with English military history and the significance that they attached to it.
[ Footnote 1 ] Although the applicability of Furman v. Georgia, 408 U.S. 238 (1972), and its progeny to the military is an open question, the United States surprisingly makes no argument that the military is exempt from the byzantine rules that we have imposed upon the States in their administration of the death penalty.
