Justice ALITO, concurring in the judgment.
The Constitution confers on Congress certain "legislative [p]owers," Art. I, § 1, and does not permit Congress to delegate them to another branch of the Government. See Whitman v. American Trucking Assns. , Inc.,
If a majority of this Court were willing to reconsider the approach we have taken for the past 84 years, I would support that effort. But because a majority is not willing to do that, it would be freakish to single out the provision at issue here for special treatment.
Because I cannot say that the statute lacks a discernable standard that is adequate under the approach this Court has taken for many years, I vote to affirm.
Justice GORSUCH, with whom THE CHIEF JUSTICE and Justice THOMAS join, dissenting.
The Constitution promises that only the people's elected representatives may adopt new federal laws restricting liberty. Yet the statute before us scrambles that design. It purports to endow the nation's chief prosecutor with the power to write his own criminal code governing the lives of a half-million citizens. Yes, those affected are some of the least popular among us. But if a single executive branch official can write laws restricting the liberty of this group of persons, what does that mean for the next?
Today, a plurality of an eight-member Court endorses this extraconstitutional arrangement but resolves nothing. Working from an understanding of the Constitution at war with its text and history, the plurality reimagines the terms of the statute before us and insists there is nothing wrong with Congress handing off so much power to the Attorney General. But Justice ALITO supplies the fifth vote for today's judgment and he does not join either the plurality's constitutional or statutory analysis, indicating instead that he remains willing, in a future case with a full Court, to revisit these matters. Respectfully, I would not wait.

For individuals convicted of sex offenses after Congress adopted the Sex Offender Registration and Notification Act (SORNA) in 2006, the statute offers detailed instructions. It requires them "to provide state governments with (and to update) information, such as names and current addresses, for inclusion on state and federal sex offender registries."
But what about those convicted of sex offenses before the Act's adoption? At the time of SORNA's enactment, the nation's population of sex offenders exceeded 500,000, and Congress concluded that something had to be done about these "pre-Act" offenders too. But it seems Congress couldn't agree what that should be. The treatment of pre-Act offenders proved a "controversial issue with major policy significance *2132and practical ramifications for states."
"The Attorney General shall have the authority to specify the applicability of the requirements of this subchapter to sex offenders convicted before the enactment of this chapter ... and to prescribe rules for the registration of any such sex offender."
Yes, that's it. The breadth of the authority Congress granted to the Attorney General in these few words can only be described as vast. As the Department of Justice itself has acknowledged, SORNA "does not require the Attorney General" to impose registration requirements on pre-Act offenders "within a certain time frame or by a date certain; it does not require him to act at all."
Unsurprisingly, different Attorneys General have exercised their discretion in different ways.
*2133These unbounded policy choices have profound consequences for the people they affect. Take our case. Before SORNA's enactment, Herman Gundy pleaded guilty in 2005 to a sexual offense. After his release from prison five years later, he was arrested again, this time for failing to register as a sex offender according to the rules the Attorney General had then prescribed for pre-Act offenders. As a result, Mr. Gundy faced an additional 10-year prison term-10 years more than if the Attorney General had, in his discretion, chosen to write the rules differently.

A
Our founding document begins by declaring that "We the People ... ordain and establish this Constitution." At the time, that was a radical claim, an assertion that sovereignty belongs not to a person or institution or class but to the whole of the people. From that premise, the Constitution proceeded to vest the authority to exercise different aspects of the people's sovereign power in distinct entities. In Article I, the Constitution entrusted all of the federal government's legislative power to Congress. In Article II, it assigned the executive power to the President. And in Article III, it gave independent judges the task of applying the laws to cases and controversies.
To the framers, each of these vested powers had a distinct content. When it came to the legislative power, the framers understood it to mean the power to adopt generally applicable rules of conduct governing future actions by private persons-the power to "prescrib[e] the rules by which the duties and rights of every citizen are to be regulated,"
The framers understood, too, that it would frustrate "the system of government ordained by the Constitution" if Congress could merely announce vague aspirations and then assign others the responsibility of adopting legislation to realize its goals.
"The legislative cannot transfer the power of making laws to any other hands; for it being but a delegated power from the people, they who have it cannot pass it over to others. The people alone can appoint the form of the commonwealth, which is by constituting the legislative, and appointing in whose hands that shall be. And when the people have said we will submit to rules, and be governed by laws made by such men, and in such forms, nobody else can say other men shall make laws for them; nor can the people be bound by any laws but such as *2134are enacted by those whom they have chosen and authorised to make laws for them."21
Why did the framers insist on this particular arrangement? They believed the new federal government's most dangerous power was the power to enact laws restricting the people's liberty.
Nor was the point only to limit the government's capacity to restrict the people's freedoms. Article I's detailed processes for new laws were also designed to promote deliberation. "The oftener the measure is brought under examination," Hamilton explained, "the greater the diversity in the situations of those who are to examine it," and "the less must be the danger of those errors which flow from want of due deliberation, or of those missteps which proceed from the contagion of some common passion or interest."
Other purposes animated the framers' design as well. Because men are not angels
If Congress could pass off its legislative power to the executive branch, the "[v]esting *2135[c]lauses, and indeed the entire structure of the Constitution," would "make no sense."
The framers warned us against permitting consequences like these. As Madison explained, " '[t]here can be no liberty where the legislative and executive powers are united in the same person, or body of magistrates.' "
B
Accepting, then, that we have an obligation to decide whether Congress has unconstitutionally divested itself of its legislative responsibilities, the question follows: What's the test? Madison acknowledged that "no skill in the science of government has yet been able to discriminate and define, with sufficient certainty, its three great provinces-the legislative, executive, and judiciary."
First, we know that as long as Congress makes the policy decisions when regulating private conduct, it may authorize another branch to "fill up the details." In Wayman v. Southard , this Court upheld a statute that instructed the federal courts to borrow state-court procedural rules but allowed them to make certain "alterations and additions." Writing for the Court, Chief Justice Marshall distinguished between those "important subjects, which must be entirely regulated by the legislature itself," and "those of less interest, in which a general provision may be made, and power given to those who are to act ... to fill up the details."
Later cases built on Chief Justice Marshall's understanding. In In re Kollock , for example, the Court upheld a statute that assigned the Commissioner of Internal Revenue the responsibility to design tax stamps for margarine packages.
Second, once Congress prescribes the rule governing private conduct, it may make the application of that rule depend on executive fact-finding. Here, too, the power extended to the executive may prove highly consequential. During the Napoleonic Wars, for example, Britain and France each tried to block the United States from trading with the other. Congress responded with a statute instructing that, if the President found that either Great Britain or France stopped interfering with American trade, a trade embargo would be imposed against the other country. In Cargo of Brig Aurora v. United States , this Court explained that it could "see no sufficient reason, why the legislature should not exercise its discretion [to impose an embargo] either expressly or conditionally , as their judgment should direct."
Third, Congress may assign the executive and judicial branches certain non-legislative responsibilities. While the Constitution vests all federal legislative power in Congress alone, Congress's legislative authority sometimes overlaps with authority the Constitution separately vests in another branch.
C
Before the 1930s, federal statutes granting authority to the executive were comparatively modest and usually easily upheld. But then the federal government began to grow explosively. And with the proliferation of new executive programs came new questions about the scope of congressional delegations. Twice the Court responded by striking down statutes for violating the separation of powers.
In A. L. A. Schechter Poultry Corp. v. United States , the Court considered a statute that transferred to the President the power "to approve 'codes of fair competition' " for slaughterhouses and other industries.
Included in the code was a rule that often made it a federal crime for butchers to allow customers to select which individual chickens they wished to buy. Kosher butchers such as the Schechters had a hard time following these rules. Yet the government apparently singled out the *2138Schechters as a test case; inspectors repeatedly visited them and, at times, apparently behaved abusively toward their customers. When the Schechters finally kicked the inspectors out, they were greeted with a criminal indictment running to dozens of counts. After a trial in which the Schechters were found guilty of selling one allegedly "unfit" chicken and other miscellaneous counts,
The same year, in Panama Refining Co. v. Ryan , the Court struck down a statute that authorized the President to decide whether and how to prohibit the interstate transportation of " 'hot oil,' " petroleum produced or withdrawn from storage in excess of state-set quotas. As in Schechter Poultry , the law provided no notice to regulated parties about what the President might wind up prohibiting, leading the Court to observe that Congress "ha[d] declared no policy, ha[d] established no standard, ha[d] laid down no rule."
After Schechter Poultry and Panama Refining , Congress responded by writing a second wave of New Deal legislation more "[c]arefully crafted" to avoid the kind of problems that sank these early statutes.
This Court first used that phrase in 1928 in J. W. Hampton, Jr., & Co. v. United States , where it remarked that a statute "lay[ing] down by legislative act an intelligible principle to which the [executive official]
*2139is directed to conform" satisfies the separation of powers.
There's a good argument, as well, that the statute in J. W. Hampton passed muster under the traditional tests. To boost American competitiveness in international trade, the legislation directed the President to " 'investigat[e]' " the relative costs of production for American companies and their foreign counterparts and impose tariffs or duties that would " 'equalize' " those costs.
Still, it's undeniable that the "intelligible principle" remark eventually began to take on a life of its own. We sometimes chide people for treating judicial opinions as if they were statutes, divorcing a passing comment from its context, ignoring all that came before and after, and treating an isolated phrase as if it were controlling.
This mutated version of the "intelligible principle" remark has no basis in the original meaning of the Constitution, in history, or even in the decision from which it was plucked. Judges and scholars representing a wide and diverse range of views have condemned it as resting on "misunderst[ood]
*2140historical foundations."
Still, the scope of the problem can be overstated. At least some of the results the Court has reached under the banner of the abused "intelligible principle" doctrine may be consistent with more traditional teachings. Some delegations have, at least arguably, implicated the president's inherent Article II authority. The Court has held, for example, that Congress may authorize the President to prescribe aggravating factors that permit a military court-martial to impose the death penalty on a member of the Armed Forces convicted of murder-a decision that may implicate in part the President's independent commander-in-chief authority.
*2141More recently, too, we've sought to tame misunderstandings of the intelligible principle "test." In Touby v. United States , the Court considered a provision of the Controlled Substances Act that allowed the Attorney General to add a substance to a list of prohibited drugs temporarily if he determined that doing so was " 'necessary to avoid an imminent hazard to the public safety.' "
While it's been some time since the Court last held that a statute improperly delegated the legislative power to another branch-thanks in no small measure to the intelligible principle misadventure-the Court has hardly abandoned the business of policing improper legislative delegations. When one legal doctrine becomes unavailable to do its intended work, the hydraulic pressures of our constitutional system sometimes shift the responsibility to different doctrines.
Consider, for example, the "major questions" doctrine. Under our precedents, an agency can fill in statutory gaps where "statutory circumstances" indicate that Congress meant to grant it such powers.
Consider, too, this Court's cases addressing vagueness. "A vague law," this Court has observed, "impermissibly delegates basic policy matters to policemen, judges, and juries for resolution on an ad hoc and subjective basis."
Nor have we abandoned enforcing other sides of the separation-of-powers triangle between the legislative, executive, and judiciary. We have not hesitated to prevent Congress from "confer[ring] the Government's 'judicial Power' on entities outside Article III."
*2143III
A
Returning to SORNA with this understanding of our charge in hand, problems quickly emerge. Start with this one: It's hard to see how SORNA leaves the Attorney General with only details to fill up. Of course, what qualifies as a detail can sometimes be difficult to discern and, as we've seen, this Court has upheld statutes that allow federal agencies to resolve even highly consequential details so long as Congress prescribes the rule governing private conduct. But it's hard to see how the statute before us could be described as leaving the Attorney General with only details to dispatch. As the government itself admitted in Reynolds , SORNA leaves the Attorney General free to impose on 500,000 pre-Act offenders all of the statute's requirements, some of them, or none of them. The Attorney General may choose which pre-Act offenders to subject to the Act. And he is free to change his mind at any point or over the course of different political administrations. In the end, there isn't a single policy decision concerning pre-Act offenders on which Congress even tried to speak, and not a single other case where we have upheld executive authority over matters like these on the ground they constitute mere "details." This much appears to have been deliberate, too. Because members of Congress could not reach consensus on the treatment of pre-Act offenders, it seems this was one of those situations where they found it expedient to hand off the job to the executive and direct there the blame for any later problems that might emerge.
Nor can SORNA be described as an example of conditional legislation subject to executive fact-finding. To be sure, Congress could have easily written this law in that way. It might have required all pre-Act offenders to register, but then given the Attorney General the authority to make case-by-case exceptions for offenders who do not present an " 'imminent hazard to the public safety' " comparable to that posed by newly released post-Act offenders.
But SORNA did none of this. Instead, it gave the Attorney General unfettered discretion to decide which requirements to impose on which pre-Act offenders. The Attorney General's own edicts acknowledge the considerable policy-making powers he enjoys, describing his rules governing pre-Act offenders as " 'of fundamental importance to the initial operation of SORNA, and to its practical scope ... since [they] determin[e] the applicability of SORNA's requirements to virtually the entire existing sex offender population.' "
Finally, SORNA does not involve an area of overlapping authority with the executive.
*2144Congress may assign the President broad authority regarding the conduct of foreign affairs or other matters where he enjoys his own inherent Article II powers. But SORNA stands far afield from any of that. It gives the Attorney General the authority to "prescrib[e] the rules by which the duties and rights" of citizens are determined, a quintessentially legislative power.
Our precedents confirm these conclusions. If allowing the President to draft a "cod[e] of fair competition" for slaughterhouses was "delegation running riot," then it's hard to see how giving the nation's chief prosecutor the power to write a criminal code rife with his own policy choices might be permissible.
The statute here also sounds all the alarms the founders left for us. Because Congress could not achieve the consensus necessary to resolve the hard problems associated with SORNA's application to pre-Act offenders, it passed the potato to the Attorney General. And freed from the need to assemble a broad supermajority for his views, the Attorney General did not hesitate to apply the statute retroactively to a politically unpopular minority. Nor could the Attorney General afford the issue the kind of deliberative care the framers designed a representative legislature to ensure. Perhaps that's part of the reason why the executive branch found itself rapidly adopting different positions across different administrations. And because SORNA vested lawmaking power in one person rather than many, it should be no surprise that, rather than few and stable, the edicts have proved frequent and shifting, with fair notice sacrificed in the process. Then, too, there is the question of accountability. In passing this statute, Congress was able to claim credit for "comprehensively" addressing the problem of the entire existing population of sex offenders (who can object to that?), while in fact leaving the Attorney General to sort it out.
It would be easy enough to let this case go. After all, sex offenders are one of the most disfavored groups in our society. But the rule that prevents Congress from giving the executive carte blanche to write laws for sex offenders is the same rule that protects everyone else. Nor is it hard to imagine how the power at issue in this case-the power of a prosecutor to require a group to register with the government on pain of weighty criminal penalties-could be abused in other settings. To allow the nation's chief law enforcement officer to write the criminal laws he is charged with enforcing-to " 'unit[e]' " the " 'legislative and executive powers ... in the same person' "-would be to mark the end of any meaningful enforcement of our separation of powers and invite the tyranny of the majority that follows when lawmaking *2145and law enforcement responsibilities are united in the same hands.
Nor would enforcing the Constitution's demands spell doom for what some call the "administrative state." The separation of powers does not prohibit any particular policy outcome, let alone dictate any conclusion about the proper size and scope of government. Instead, it is a procedural guarantee that requires Congress to assemble a social consensus before choosing our nation's course on policy questions like those implicated by SORNA. What is more, Congress is hardly bereft of options to accomplish all it might wish to achieve. It may always authorize executive branch officials to fill in even a large number of details, to find facts that trigger the generally applicable rule of conduct specified in a statute, or to exercise non-legislative powers. Congress can also commission agencies or other experts to study and recommend legislative language. Respecting the separation of powers forecloses no substantive outcomes. It only requires us to respect along the way one of the most vital of the procedural protections of individual liberty found in our Constitution.
B
What do the government and the plurality have to say about the constitutional concerns SORNA poses? Most everyone, the plurality included, concedes that if SORNA allows the Attorney General as much authority as we have outlined, it would present "a nondelegation question."
But even this new dream of a statute wouldn't be free from doubt. A statute directing an agency to regulate private conduct to the extent "feasible" can have many possible meanings: It might refer to "technological" feasibility, "economic" feasibility, "administrative" feasibility, or even "political" feasibility. Such an "evasive standard" could threaten the separation of powers if it effectively allowed the agency to make the "important policy choices" that belong to Congress while frustrating "meaningful judicial review."
But don't worry over that; return to the real world. The bigger problem is that the feasibility standard is a figment of the government's (very recent) imagination.
*2146The only provision addressing pre-Act offenders, § 20913(d), says nothing about feasibility. And the omission can hardly be excused as some oversight: No one doubts that Congress knows exactly how to write a feasibility standard into law when it wishes.
Unable to muster a feasibility standard from the only statutory provision addressing pre-Act offenders, the plurality invites us to hunt in other and more unlikely corners. It points first to SORNA's "[d]eclaration of purpose," which announces that Congress, "[i]n order to protect the public from sex offenders and offenders against children ... establishes a comprehensive national system for the registration of those offenders."
Besides, even if we were to pretend that § 20901 amounted to a directive telling the Attorney General to establish a "comprehensive national system" for pre-Act offenders, the plurality reads too much into the word "comprehensive." Comprehensive coverage does not mean coverage to the maximum extent feasible. "Comprehensive" means "having the attribute of comprising or including much; of large content or scope," "[i]nclusive of; embracing," or "[c]ontaining much in small compass; compendious."
Finding it impossible to conscript the statute's declaration of purpose into doing the work it needs done, the government and plurality next ask us to turn to SORNA's definition of " 'sex offender.' "
That much, however, does not follow. To say that pre-Act sex offenders fall within the definition of "sex offenders" is merely a truism: Yes, of course, these people have already been convicted of sex offenses under state law. But whether these individuals are also subject to federal registration requirements is a different question entirely. And as we have seen, the only part of the statute that speaks to pre-Act sex offenders- § 20913(d) -makes plain that they are not automatically subject to all the Act's terms but are left to their fate at the hands of the Attorney General. Look at it this way: If the statute's definitional section were really enough to command the registration of all sex offenders, the Act would have had no need to proceed to explain, as it does at great length, when post- Act sex offenders must register and when they need not.
If that argument won't work, the plurality points us to § 20913(d)'s second clause, which grants the Attorney General the authority "to prescribe rules for the registration of ... sex offenders ... who are unable to comply" with the Act's initial registration requirements.
With so little in statutory text to work with, the government and the plurality "can't resist" highlighting certain statements from the Act's legislative history.
That leaves the plurality and the government to try to fish its feasibility standard from our decision in Reynolds . But Reynolds would make a difference only if it bound us as a matter of stare decisis to adopt an interpretation inconsistent with the statute's terms. And, of course, it does no such thing. The government and the plurality submit that Reynolds was premised on an understanding that Congress intended the statute to apply to pre-Act offenders to the maximum extent feasible. To support their reading they point to Reynolds ' surmise that Congress "may well have thought [that there could be] practical problems" with applying SORNA to pre-Act offenders and for that reason left their registration obligations to be sorted out by the Attorney General.
*
Nothing found here can come as a surprise. In Reynolds , the government told this Court that SORNA supplies no standards regulating the Attorney General's treatment of pre-Act offenders. This Court agreed, and everyone proceeded with eyes open about the potential constitutional consequences; in fact, the dissent expressly warned that adopting such a broad construction of the statute would yield the separation-of-powers challenge we face today.
The only real surprise is that the Court fails to make good on the consequences the government invited, resolving nothing and deferring everything. In a future case with a full panel, I remain hopeful that the Court may yet recognize that, while Congress can enlist considerable assistance from the executive branch in filling up details and finding facts, it may never hand off to the nation's chief prosecutor the power to write his own criminal code. That "is delegation running riot."
