JUSTICE WHITE delivered the opinion of the Court.

In determining whether the search at issue in this case violated the Fourth Amendment, we are faced initially with the question whether that Amendment's prohibition on unreasonable searches and seizures applies to searches conducted by public school officials. We hold that it does.

***

Notwithstanding the general applicability of the Fourth Amendment to the activities of civil authorities, a few courts have concluded that school officials are exempt from the dictates of the Fourth Amendment by virtue of the special nature of their authority over schoolchildren. See, e. g., R. C. M. v. State, 660 S. W. 2d 552 (Tex. App. 1983). Teachers and school administrators, it is said, act in loco parentis in their dealings with students: their authority is that of the parent, not the State, and is therefore not subject to the limits of the Fourth Amendment. Ibid.

Such reasoning is in tension with contemporary reality and the teachings of this Court. We have held school officials subject to the commands of the First Amendment, see Tinker v. Des Moines Independent Community School District, 393 U.S. 503 (1969), and the Due Process Clause of the Fourteenth Amendment, see Goss v. Lopez, 419 U.S. 565 (1975). If school authorities are state actors for purposes of the constitutional guarantees of freedom of expression and due process, it is difficult to understand why they should be deemed to be exercising parental rather than public authority when conducting searches of their students. More generally, the Court has recognized that "the concept of parental delegation" as a source of school authority is not entirely "consonant with compulsory education laws." Ingraham v. Wright, 430 U.S. 651, 662 (1977). Today's public school officials do not merely exercise authority voluntarily conferred on them by individual parents; rather, they act in furtherance of publicly mandated educational and disciplinary policies. See, e. g., the opinion in State ex rel. T. L. O., 94 N. J., at 343, 463 A. 2d, at 934, 940, describing the New Jersey statutes regulating school disciplinary policies and establishing the authority of school officials over their students. In carrying out searches and other disciplinary functions pursuant to such policies, school officials act as representatives of the State, not merely as surrogates for the parents, and they cannot claim the parents' immunity from the strictures of the Fourth Amendment.

To hold that the Fourth Amendment applies to searches conducted by school authorities is only to begin the inquiry into the standards governing such searches. Although the underlying command of the Fourth Amendment is always that searches and seizures be reasonable, what is reasonable depends on the context within which a search takes place. The determination of the standard of reasonableness governing any specific class of searches requires "balancing the need to search against the invasion which the search entails." Camara v. Municipal Court, supra, at 536-537. On one side of the balance are arrayed the individual's legitimate expectations of privacy and personal security; on the other, the government's need for effective methods to deal with breaches of public order.

We have recognized that even a limited search of the person is a substantial invasion of privacy. Terry v. Ohio, 392 U.S. 1, 24-25 (1967). We have also recognized that searches of closed items of personal luggage are intrusions on protected privacy interests, for "the Fourth Amendment provides protection to the owner of every container that conceals its contents from plain view." United States v. Ross, 456 U.S. 798, 822-823 (1982). A search of a child's person or of a closed purse or other bag carried on her person, no less than a similar search carried out on an adult, is undoubtedly a severe violation of subjective expectations of privacy.

Of course, the Fourth Amendment does not protect subjective expectations of privacy that are unreasonable or otherwise "illegitimate." See, e. g., Hudson v. Palmer, 468 U.S. 517 (1984); Rawlings v. Kentucky, 448 U.S. 98 (1980). To receive the protection of the Fourth Amendment, an expectation of privacy must be one that society is "prepared to recognize as legitimate." Hudson v. Palmer, supra, at 526. The State of New Jersey has argued that because of the pervasive supervision to which children in the schools are necessarily subject, a child has virtually no legitimate expectation of privacy in articles of personal property "unnecessarily" carried into a school. This argument has two factual premises: (1) the fundamental incompatibility of expectations of privacy with the maintenance of a sound educational environment; and (2) the minimal interest of the child in bringing any items of personal property into the school. Both premises are severely flawed.

Although this Court may take notice of the difficulty of maintaining discipline in the public schools today, the situation is not so dire that students in the schools may claim no legitimate expectations of privacy. We have recently recognized that the need to maintain order in a prison is such that prisoners retain no legitimate expectations of privacy in their cells, but it goes almost without saying that "[t]he prisoner and the schoolchild stand in wholly different circumstances, separated by the harsh facts of criminal conviction and incarceration." Ingraham v. Wright, supra, at 669. We are not yet ready to hold that the schools and the prisons need be equated for purposes of the Fourth Amendment.

Nor does the State's suggestion that children have no legitimate need to bring personal property into the schools seem well anchored in reality. Students at a minimum must bring to school not only the supplies needed for their studies, but also keys, money, and the necessaries of personal hygiene and grooming. In addition, students may carry on their persons or in purses or wallets such nondisruptive yet highly personal items as photographs, letters, and diaries. Finally, students may have perfectly legitimate reasons to carry with them articles of property needed in connection with extracurricular or recreational activities. In short, schoolchildren may find it necessary to carry with them a variety of legitimate, noncontraband items, and there is no reason to conclude that they have necessarily waived all rights to privacy in such items merely by bringing them onto school grounds.

Against the child's interest in privacy must be set the substantial interest of teachers and administrators in maintaining discipline in the classroom and on school grounds. Maintaining order in the classroom has never been easy, but in recent years, school disorder has often taken particularly ugly forms: drug use and violent crime in the schools have become major social problems. See generally 1 NIE, U.S. Dept. of Health, Education and Welfare, Violent Schools - Safe Schools: The Safe School Study Report to the Congress (1978). Even in schools that have been spared the most severe disciplinary problems, the preservation of order and a proper educational environment requires close supervision of schoolchildren, as well as the enforcement of rules against conduct that would be perfectly permissible if undertaken by an adult. "Events calling for discipline are frequent occurrences and sometimes require immediate, effective action." Goss v. Lopez, 419 U.S., at 580. Accordingly, we have recognized that maintaining security and order in the schools requires a certain degree of flexibility in school disciplinary procedures, and we have respected the value of preserving the informality of the student-teacher relationship. See id., at 582-583; Ingraham v. Wright, 430 U.S., at 680-682.

How, then, should we strike the balance between the schoolchild's legitimate expectations of privacy and the school's equally legitimate need to maintain an environment in which learning can take place? It is evident that the school setting requires some easing of the restrictions to which searches by public authorities are ordinarily subject. The warrant requirement, in particular, is unsuited to the school environment: requiring a teacher to obtain a warrant before searching a child suspected of an infraction of school rules (or of the criminal law) would unduly interfere with the maintenance of the swift and informal disciplinary procedures needed in the schools. Just as we have in other cases dispensed with the warrant requirement when "the burden of obtaining a warrant is likely to frustrate the governmental purpose behind the search," Camara v. Municipal Court, 387 U.S., at 532-533, we hold today that school officials need not obtain a warrant before searching a student who is under their authority.

The school setting also requires some modification of the level of suspicion of illicit activity needed to justify a search. Ordinarily, a search - even one that may permissibly be carried out without a warrant - must be based upon "probable cause" to believe that a violation of the law has occurred. See, e. g., Almeida-Sanchez v. United States, 413 U.S. 266, 273 (1973); Sibron v. New York, 392 U.S. 40, 62-66 (1968). However, "probable cause" is not an irreducible requirement of a valid search. The fundamental command of the Fourth Amendment is that searches and seizures be reasonable, and although "both the concept of probable cause and the requirement of a warrant bear on the reasonableness of a search, . . . in certain limited circumstances neither is required." Almeida-Sanchez v. United States, supra, at 277 (POWELL, J., concurring). Thus, we have in a number of cases recognized the legality of searches and seizures based on suspicions that, although "reasonable," do not rise to the level of probable cause. See, e. g., Terry v. Ohio, 392 U.S. 1 (1968); United States v. Brignoni-Ponce, 422 U.S. 873, 881 (1975); Delaware v. Prouse, 440 U.S. 648, 654-655 (1979); United States v. Martinez-Fuerte, 428 U.S. 543 (1976); cf. Camara v. Municipal Court, supra, at 534-539. Where a careful balancing of governmental and private interests suggests that the public interest is best served by a Fourth Amendment standard of reasonableness that stops short of probable cause, we have not hesitated to adopt such a standard.

We join the majority of courts that have examined this issue in concluding that the accommodation of the privacy interests of schoolchildren with the substantial need of teachers and administrators for freedom to maintain order in the schools does not require strict adherence to the requirement that searches be based on probable cause to believe that the subject of the search has violated or is violating the law. Rather, the legality of a search of a student should depend simply on the reasonableness, under all the circumstances, of the search. Determining the reasonableness of any search involves a twofold inquiry: first, one must consider "whether the . . . action was justified at its inception," Terry v. Ohio, 392 U.S., at 20; second, one must determine whether the search as actually conducted "was reasonably related in scope to the circumstances which justified the interference in the first place," ibid. Under ordinary circumstances, a search of a student by a teacher or other school official will be "justified at its inception" when there are reasonable grounds for suspecting that the search will turn up evidence that the student has violated or is violating either the law or the rules of the school. Such a search will be permissible in its scope when the measures adopted are reasonably related to the objectives of the search and not excessively intrusive in light of the age and sex of the student and the nature of the infraction.

This standard will, we trust, neither unduly burden the efforts of school authorities to maintain order in their schools nor authorize unrestrained intrusions upon the privacy of schoolchildren. By focusing attention on the question of reasonableness, the standard will spare teachers and school administrators the necessity of schooling themselves in the niceties of probable cause and permit them to regulate their conduct according to the dictates of reason and common sense. At the same time, the reasonableness standard should ensure that the interests of students will be invaded no more than is necessary to achieve the legitimate end of preserving order in the schools.

There remains the question of the legality of the search in this case…

The incident that gave rise to this case actually involved two separate searches, with the first - the search for cigarettes - providing the suspicion that gave rise to the second - the search for marihuana. Although it is the fruits of the second search that are at issue here, the validity of the search for marihuana must depend on the reasonableness of the initial search for cigarettes, as there would have been no reason to suspect that T. L. O. possessed marihuana had the first search not taken place. Accordingly, it is to the search for cigarettes that we first turn our attention.

The New Jersey Supreme Court pointed to two grounds for its holding that the search for cigarettes was unreasonable. First, the court observed that possession of cigarettes was not in itself illegal or a violation of school rules. Because the contents of T. L. O.'s purse would therefore have "no direct bearing on the infraction" of which she was accused (smoking in a lavatory where smoking was prohibited), there was no reason to search her purse. Second, even assuming that a search of T. L. O.'s purse might under some circumstances be reasonable in light of the accusation made against T. L. O., the New Jersey court concluded that Mr. Choplick in this particular case had no reasonable grounds to suspect that T. L. O. had cigarettes in her purse. At best, according to the court, Mr. Choplick had "a good hunch." 94 N. J., at 347, 463 A. 2d, at 942.

Both these conclusions are implausible. T. L. O. had been accused of smoking, and had denied the accusation in the strongest possible terms when she stated that she did not smoke at all. Surely it cannot be said that under these circumstances, T. L. O.'s possession of cigarettes would be irrelevant to the charges against her or to her response to those charges. T. L. O.'s possession of cigarettes, once it was discovered, would both corroborate the report that she had been smoking and undermine the credibility of her defense to the charge of smoking. To be sure, the discovery of the cigarettes would not prove that T. L. O. had been smoking in the lavatory; nor would it, strictly speaking, necessarily be inconsistent with her claim that she did not smoke at all. But it is universally recognized that evidence, to be relevant to an inquiry, need not conclusively prove the ultimate fact in issue, but only have "any tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence." Fed. Rule Evid. 401. The relevance of T. L. O.'s possession of cigarettes to the question whether she had been smoking and to the credibility of her denial that she smoked supplied the necessary "nexus" between the item searched for and the infraction under investigation. See Warden v. Hayden, 387 U.S. 294, 306-307 (1967). Thus, if Mr. Choplick in fact had a reasonable suspicion that T. L. O. had cigarettes in her purse, the search was justified despite the fact that the cigarettes, if found, would constitute "mere evidence" of a violation. Ibid.

***

Our conclusion that Mr. Choplick's decision to open T. L. O.'s purse was reasonable brings us to the question of the further search for marihuana once the pack of cigarettes was located. The suspicion upon which the search for marihuana was founded was provided when Mr. Choplick observed a package of rolling papers in the purse as he removed the pack of cigarettes. Although T. L. O. does not dispute the reasonableness of Mr. Choplick's belief that the rolling papers indicated the presence of marihuana, she does contend that the scope of the search Mr. Choplick conducted exceeded permissible bounds when he seized and read certain letters that implicated T. L. O. in drug dealing. This argument, too, is unpersuasive. The discovery of the rolling papers concededly gave rise to a reasonable suspicion that T. L. O. was carrying marihuana as well as cigarettes in her purse. This suspicion justified further exploration of T. L. O.'s purse, which turned up more evidence of drug-related activities: a pipe, a number of plastic bags of the type commonly used to store marihuana, a small quantity of marihuana, and a fairly substantial amount of money. Under these circumstances, it was not unreasonable to extend the search to a separate zippered compartment of the purse; and when a search of that compartment revealed an index card containing a list of "people who owe me money" as well as two letters, the inference that T. L. O. was involved in marihuana trafficking was substantial enough to justify Mr. Choplick in examining the letters to determine whether they contained any further evidence. In short, we cannot conclude that the search for marihuana was unreasonable in any respect.

Because the search resulting in the discovery of the evidence of marihuana dealing by T. L. O. was reasonable, the New Jersey Supreme Court's decision to exclude that evidence from T. L. O.'s juvenile delinquency proceedings on Fourth Amendment grounds was erroneous. Accordingly, the judgment of the Supreme Court of New Jersey is

[Concurring opinion of Justice Powell, joined by Justice O'Connor, is omitted.]

[Concurring Opinion of Justice Blackmun is omitted.]

JUSTICE BRENNAN, with whom JUSTICE MARSHALL joins, concurring in part and dissenting in part.

I fully agree with Part II of the Court's opinion. Teachers, like all other government officials, must conform their conduct to the Fourth Amendment's protections of personal privacy and personal security. As JUSTICE STEVENS points out, post, at 373-374, 385-386, this principle is of particular importance when applied to schoolteachers, for children learn as much by example as by exposition. It would be incongruous and futile to charge teachers with the task of embuing their students with an understanding of our system of constitutional democracy, while at the same time immunizing those same teachers from the need to respect constitutional protections. See Board of Education v. Pico, 457 U.S. 853, 864-865 (1982) (plurality opinion); West Virginia State Board of Education v. Barnette, 319 U.S. 624, 637 (1943).

I do not, however, otherwise join the Court's opinion. Today's decision sanctions school officials to conduct fullscale searches on a "reasonableness" standard whose only definite content is that it is not the same test as the "probable cause" standard found in the text of the Fourth Amendment. In adopting this unclear, unprecedented, and unnecessary departure from generally applicable Fourth Amendment standards, the Court carves out a broad exception to standards that this Court has developed over years of considering Fourth Amendment problems. Its decision is supported neither by precedent nor even by a fair application of the "balancing test" it proclaims in this very opinion.

***

I emphatically disagree with the Court's decision to cast aside the constitutional probable-cause standard when assessing the constitutional validity of a schoolhouse search. The Court's decision jettisons the probable-cause standard - the only standard that finds support in the text of the Fourth Amendment - on the basis of its Rohrschach-like "balancing test." Use of such a "balancing test" to determine the standard for evaluating the validity of a full-scale search represents a sizable innovation in Fourth Amendment analysis. This innovation finds support neither in precedent nor policy and portends a dangerous weakening of the purpose of the Fourth Amendment to protect the privacy and security of our citizens…Therefore, because I believe that the balancing test used by the Court today is flawed both in its inception and in its execution, I respectfully dissent.

Our holdings that probable cause is a prerequisite to a full-scale search are based on the relationship between the two Clauses of the Fourth Amendment. The first Clause ("The right of the people to be secure in their persons, houses, papers and effects, against unreasonable searches and seizures, shall not be violated . . .") states the purpose of the Amendment and its coverage. The second Clause (". . . and no Warrants shall issue but upon probable cause . . .") gives content to the word "unreasonable" in the first Clause. "For all but . . . narrowly defined intrusions, the requisite `balancing' has been performed in centuries of precedent and is embodied in the principle that seizures are `reasonable' only if supported by probable cause." Dunaway v. New York, 442 U.S., at 214.

I therefore fully agree with the Court that "the underlying command of the Fourth Amendment is always that searches and seizures be reasonable." Ante, at 337. But this "underlying command" is not directly interpreted in each category of cases by some amorphous "balancing test." Rather, the provisions of the Warrant Clause - a warrant and probable cause - provide the yardstick against which official searches and seizures are to be measured. The Fourth Amendment neither requires nor authorizes the conceptual free-for-all that ensues when an unguided balancing test is used to assess specific categories of searches. If the search in question is more than a minimally intrusive Terry stop, the constitutional probable-cause standard determines its validity.

***

A legitimate balancing test whose function was something more substantial than reaching a predetermined conclusion acceptable to this Court's impressions of what authority teachers need would therefore reach rather a different result than that reached by the Court today. On one side of the balance would be the costs of applying traditional Fourth Amendment standards - the "practical" and "flexible" probable-cause standard where a full-scale intrusion is sought, a lesser standard in situations where the intrusion is much less severe and the need for greater authority compelling. Whatever costs were toted up on this side would have to be discounted by the costs of applying an unprecedented and ill-defined "reasonableness under all the circumstances" test that will leave teachers and administrators uncertain as to their authority and will encourage excessive fact-based litigation.

On the other side of the balance would be the serious privacy interests of the student, interests that the Court admirably articulates in its opinion, ante, at 337-339, but which the Court's new ambiguous standard places in serious jeopardy. I have no doubt that a fair assessment of the two sides of the balance would necessarily reach the same conclusion that, as I have argued above, the Fourth Amendment's language compels - that school searches like that conducted in this case are valid only if supported by probable cause.

Applying the constitutional probable-cause standard to the facts of this case, I would find that Mr. Choplick's search violated T. L. O.'s Fourth Amendment rights. After escorting T. L. O. into his private office, Mr. Choplick demanded to see her purse. He then opened the purse to find evidence of whether she had been smoking in the bathroom. When he opened the purse, he discovered the pack of cigarettes. At this point, his search for evidence of the smoking violation was complete.

Mr. Choplick then noticed, below the cigarettes, a pack of cigarette rolling papers. Believing that such papers were "associated," see ante, at 328, with the use of marihuana, he proceeded to conduct a detailed examination of the contents of her purse, in which he found some marihuana, a pipe, some money, an index card, and some private letters indicating that T. L. O. had sold marihuana to other students. The State sought to introduce this latter material in evidence at a criminal proceeding, and the issue before the Court is whether it should have been suppressed.

On my view of the case, we need not decide whether the initial search conducted by Mr. Choplick - the search for evidence of the smoking violation that was completed when Mr. Choplick found the pack of cigarettes - was valid. For Mr. Choplick at that point did not have probable cause to continue to rummage through T. L. O.'s purse. Mr. Choplick's suspicion of marihuana possession at this time was based solely on the presence of the package of cigarette papers. The mere presence without more of such a staple item of commerce is insufficient to warrant a person of reasonable caution in inferring both that T. L. O. had violated the law by possessing marihuana and that evidence of that violation would be found in her purse. Just as a police officer could not obtain a warrant to search a home based solely on his claim that he had seen a package of cigarette papers in that home, Mr. Choplick was not entitled to search possibly the most private possessions of T. L. O. based on the mere presence of a package of cigarette papers. Therefore, the fruits of this illegal search must be excluded and the judgment of the New Jersey Supreme Court affirmed.

***

On my view, the presence of the word "unreasonable" in the text of the Fourth Amendment does not grant a shifting majority of this Court the authority to answer all Fourth Amendment questions by consulting its momentary vision of the social good. Full-scale searches unaccompanied by probable cause violate the Fourth Amendment. I do not pretend that our traditional Fourth Amendment doctrine automatically answers all of the difficult legal questions that occasionally arise. I do contend, however, that this Court has an obligation to provide some coherent framework to resolve such questions on the basis of more than a conclusory recitation of the results of a "balancing test." The Fourth Amendment itself supplies that framework and, because the Court today fails to heed its message, I must respectfully dissent.

JUSTICE STEVENS, with whom JUSTICE MARSHALL joins, and with whom JUSTICE BRENNAN joins as to Part I, concurring in part and dissenting in part.

Assistant Vice Principal Choplick searched T. L. O.'s purse for evidence that she was smoking in the girls' restroom. Because T. L. O.'s suspected misconduct was not illegal and did not pose a serious threat to school discipline, the New Jersey Supreme Court held that Choplick's search of her purse was an unreasonable invasion of her privacy and that the evidence which he seized could not be used against her in criminal proceedings. The New Jersey court's holding was a careful response to the case it was required to decide.

***

The "limited search for weapons" in Terry was justified by the "immediate interest of the police officer in taking steps to assure himself that the person with whom he is dealing is not armed with a weapon that could unexpectedly and fatally be used against him." 392 U.S., at 23, 25. When viewed from the institutional perspective, "the substantial need of teachers and administrators for freedom to maintain order in the schools," ante, at 341 (majority opinion), is no less acute. Violent, unlawful, or seriously disruptive conduct is fundamentally inconsistent with the principal function of teaching institutions which is to educate young people and prepare them for citizenship. When such conduct occurs amidst a sizable group of impressionable young people, it creates an explosive atmosphere that requires a prompt and effective response.

Thus, warrantless searches of students by school administrators are reasonable when undertaken for those purposes. But the majority's statement of the standard for evaluating the reasonableness of such searches is not suitably adapted to that end. The majority holds that "a search of a student by a teacher or other school official will be `justified at its inception' when there are reasonable grounds for suspecting that the search will turn up evidence that the student has violated or is violating either the law or the rules of the school." Ante, at 341-342. This standard will permit teachers and school administrators to search students when they suspect that the search will reveal evidence of even the most trivial school regulation or precatory guideline for student behavior. The Court's standard for deciding whether a search is justified "at its inception" treats all violations of the rules of the school as though they were fungible. For the Court, a search for curlers and sunglasses in order to enforce the school dress code is apparently just as important as a search for evidence of heroin addiction or violent gang activity.

***

The logic of distinguishing between minor and serious offenses in evaluating the reasonableness of school searches is almost too clear for argument. In order to justify the serious intrusion on the persons and privacy of young people that New Jersey asks this Court to approve, the State must identify "some real immediate and serious consequences." McDonald v. United States, 335 U.S. 451, 460 (1948) (Jackson, J., concurring, joined by Frankfurter, J.). While school administrators have entirely legitimate reasons for adopting school regulations and guidelines for student behavior, the authorization of searches to enforce them "displays a shocking lack of all sense of proportion." Id., 459.

***

In the view of the state court, there is a quite obvious and material difference between a search for evidence relating to violent or disruptive activity, and a search for evidence of a smoking rule violation. This distinction does not imply that a no-smoking rule is a matter of minor importance. Rather, like a rule that prohibits a student from being tardy, its occasional violation in a context that poses no threat of disrupting school order and discipline offers no reason to believe that an immediate search is necessary to avoid unlawful conduct, violence, or a serious impairment of the educational process.

***

In this case, Mr. Choplick overreacted to what appeared to be nothing more than a minor infraction - a rule prohibiting smoking in the bathroom of the freshmen's and sophomores' building. It is, of course, true that he actually found evidence of serious wrongdoing by T. L. O., but no one claims that the prior search may be justified by his unexpected discovery. As far as the smoking infraction is concerned, the search for cigarettes merely tended to corroborate a teacher's eyewitness account of T. L. O.'s violation of a minor regulation designed to channel student smoking behavior into designated locations. Because this conduct was neither unlawful nor significantly disruptive of school order or the educational process, the invasion of privacy associated with the forcible opening of T. L. O.'s purse was entirely unjustified at its inception.

A review of the sampling of school search cases relied on by the Court demonstrates how different this case is from those in which there was indeed a valid justification for intruding on a student's privacy. In most of them the student was suspected of a criminal violation; in the remainder either violence or substantial disruption of school order or the integrity of the academic process was at stake. Few involved matters as trivial as the no-smoking rule violated by T. L. O. The rule the Court adopts today is so open-ended that it may make the Fourth Amendment virtually meaningless in the school context. Although I agree that school administrators must have broad latitude to maintain order and discipline in our classrooms, that authority is not unlimited.

The schoolroom is the first opportunity most citizens have to experience the power of government. Through it passes every citizen and public official, from schoolteachers to policemen and prison guards. The values they learn there, they take with them in life. One of our most cherished ideals is the one contained in the Fourth Amendment: that the government may not intrude on the personal privacy of its citizens without a warrant or compelling circumstance. The Court's decision today is a curious moral for the Nation's youth….

I respectfully dissent.
