[171]*171VAN HOOMISSEN, J.
This is a habeas corpus proceeding. See ORS 34.310 et seg (describing habeas corpus procedures). The trial court denied plaintiffs petition as meritless. The Court of Appeals reversed. Billings v. Gates, 133 Or App 236, 244, 890 P2d 995 (1995). The sole issue presented is the correct standard under Article I, section 16, of the Oregon Constitution,1 for testing this petition for habeas corpus. We affirm the decision of the Court of Appeals, but on different grounds.
Plaintiff Billings, an inmate at Snake River Correctional Institution (SRCI), petitioned for a writ of habeas corpus, alleging that defendant Gates, the superintendent of SRCI, had denied him proper medical treatment.2 Plaintiffs petition alleged in part:
“The shoes the institution has [have] no arch supports, and [plaintiff] has attempted to address this problem, because any walking causes the [plaintiff] pain to the point where he cannot walk. When the Doctor did see the [plaintiff], he told him that he has high arches, will have to buy arch supports off of the commissary, that SRCI will not provide arch supports, even where the [plaintiff] is indigent and unable to pay for arch supports for his bad feet. Thus, denying the [plaintiff] proper medical treatment.”
Plaintiff did not cite any authority in support of his claim. The trial court ordered defendant to show cause why the writ should not be allowed.3
[172]*172 Defendant’s response alleged that plaintiff is being provided “constitutionally adequate” medical care and asked that his petition be denied on the ground that it failed to state a claim for habeas corpus relief.4 In a legal memorandum submitted with his response, defendant argued that the standard of care recognized in Estelle v. Gamble, 429 US 97, 97 S Ct 285, 50 L Ed 2d 251, reh’g den 429 US 1066 (1976),5 under the Eighth Amendment to the United States Constitution,6 should be followed under Article I, section 16, of the Oregon Constitution. Defendant also asserted that, if the Estelle standard were applied, plaintiff could not prevail.
Relying on defendant’s response and on factual materials attached to that response by defendant, the trial court entered this judgment:
“Plaintiff suffers from Pes Cavus, an exaggeration of the normal arch of the foot. Plaintiff received a Physician’s Order on December 27th, 1993, allowing him to purchase arch supports with his own funds. Obviously, Plaintiff and [173]*173the Institution’s Health Services Unit differ with respect to whether the arch supports are medically necessary.
“To prevail on this type of claim, Plaintiff must show that the Defendant was deliberately indifferent to his serious medical need. A difference of opinion as to whether the arch supports are ‘medically necessary1 does not establish deliberate indifference. Plaintiff chooses not to use any of the funds placed in his account for arch supports. Such is his right. Plaintiff cannot, however, in turn force [defendant] to pay for his arch supports under the circumstances found in this case. OAR 291-124-085(2) is not Constitutionally void on its face nor do the circumstances in this case involve a deprivation of a Constitutional right requiring immediate judicial attention. ORS 34.362.
“NOW THEREFORE, PLAINTIFF’S PETITION IS MERITLESS IN THAT THE RELIEF HE SEEKS IS NOT AVAILABLE UNDER A HABEAS CORPUS PROCEEDING. NOW THERE [sic], IT IS HEREBY ORDERED THAT PLAINTIFF’S PETITION BE, AND IT IS HEREBY, DISMISSED.
“IT IS FURTHER ORDERED THAT JUDGMENT BE, AND IT IS HEREBY, GIVEN IN FAVOR OF DEFENDANT. ORS 34.370(2)(b)(A).”7
In denying the petition, the trial court did not specify whether it was applying a state or federal constitutional standard, assuming that the two are different. However, from the text and context of the trial court’s ruling, it is apparent that the court based its decision on a conclusion that plaintiffs petition did not meet either standard, state or federal. Plaintiff appealed. ORS 34.710. On appeal, plaintiff [174]*174relied exclusively on Article I, section 16, of the Oregon Constitution.
The Court of Appeals first concluded that a summary ruling on a show cause order issued pursuant to ORS 34.370(1) and (2) must be made on the basis of the sufficiency of the habeas corpus pleadings alone. The court held that the trial court’s consideration of the factual materials attached to defendant’s response was error. Billings, 133 Or App at 239-41. Defendant does not seek review of that holding, and we do not address it. The court also held that plaintiffs petition adequately pleads that his claim requires immediate judicial attention and that no other timely remedy is practicably available to him. Defendant does not seek review of that holding, and we do not address it.
The Court of Appeals then reversed, reaffirming its holding in Priest v. Cupp, 24 Or App 429, 545 P2d 917, rev den (1976), that under Article I, section 16, prison inmates must
“ ‘be afforded such medical care in the form of diagnosis and treatment as is reasonably available under the circumstances of [their] confinement.’ 24 Or App at 431 .’’Billings, 133 Or App at 241.
The court concluded that, under a “reasonably available” standard, plaintiffs petition stated a sufficient claim for habeas corpus relief. Id. at 243. We allowed defendant’s petition for review to consider whether the Court of Appeals applied the correct standard under Article I, section 16 — an issue of first impression for this court.
Defendant argues that this court should adopt the same standard under Article I, section 16, that the United States Supreme Court recognized for an Eighth Amendment violation in Estelle. Plaintiff responds that Estelle’s “deliberate indifference” standard results in convoluted and costly inquiries into the subjective intentions of prison officials. Plaintiff also argues that the Court of Appeals’ “reasonably available” standard correctly focuses on the seriousness of plaintiffs medical condition and on the availability and reasonableness of potential treatment, given the conditions of his confinement.
[175]*175Article I, section 16, closely parallels the Eighth Amendment. In interpreting a provision of the Oregon Constitution, however, this court is not bound by an interpretation of the United States Supreme Court relating to a parallel provision of the federal constitution. State ex rel Juv. Dept. v. Rogers, 314 Or 114, 118, 836 P2d 127 (1992).
In considering state law claims, particularly claims of first impression, this court has expressed a preference for principled arguments as opposed to mere citations from other jurisdictions. State v. Kennedy, 295 Or 260, 266-67, 666 P2d 1316 (1983). Litigants are expected to scrutinize and expound on state constitutional provisions. Id.; see also Dept. of Trans, v. Lundberg, 312 Or 568, 572 n 4, 825 P2d 641, cert den 113 S Ct 467 (1992) (because the defendants did not suggest any different analysis under the Oregon Constitution than under the United States Constitution, court would assume for purposes of the case, without deciding, that the analysis would be the same under the state constitution); State v. Mendez, 308 Or 9, 19, 774 P2d 1082 (1989) (refusing to consider a state constitutional claim when the party failed to raise any constitutional argument in the trial court and also failed to brief or argue any independent state constitutional theory on appeal).
In determining the proper standard of medical care that Oregon prison officials owe inmates under Article I, section 16, we address three aspects of that provision: its specific wording, the case law surrounding it, and the historical circumstances that led to its creation. See Priest v. Pearce, 314 Or 411, 415-16, 840 P2d 65 (1992) (stating method of analysis in interpreting Article I, section 14).
TEXT AND CONTEXT
Although the framers of the Oregon Constitution did not express what they meant by “cruel and unusual punishments,”8 that phrase appearing in the federal and early state [176]*176constitutions was commonly understood to proscribe “tortures” and other “barbarous” methods of punishment. Estelle, 429 US at 102. See Gregg v. Georgia, 428 US 153, 169-73, 96 S Ct 2909, 49 L Ed 2d 859 (1976) (joint opinion of Stewart, Powell, and Stevens, JJ.) (announcing the judgment of the Court and discussing history of “cruel and unusual punishments” clause); see also Anthony F. Granucci, “Nor Cruel and Unusual Punishments Inflicted". The Original Meaning, 57 Ca L Rev 839, 842 (1969). Early Supreme Court decisions have concluded that punishments were cruel and unusual when they involved “torture or a lingering death.” In re Kemmler, 136 US 436, 447, 10 S Ct 930, 34 L Ed 519 (1890) (citing Wilkerson v. Utah, 99 US 130, 136, 25 L Ed 345 (1878)). Alternatively, a punishment would be cruel and unusual and, thus, unlawful, if it was “so manifestly out of all proportion to the offence as to shock the moral sense with its barbarity, or because it is a punishment long disused for its cruelty until it has become unusual.” Bouvier’s Law Dictionary, Vol. 2, 796 (1897 ed) (citing Cooley, Constitutional Limitations, 401-03). Cf. Theatre West of Lincoln City, Ltd. v. Dept. of Rev., 319 Or 114, 119, 873 P2d 1083 (1994) (examining early dictionaries in seeking meaning of statute). “Cruel” also suggests a high degree of pain or suffering. Cf. State v. Cornell / Pinnell, 304 Or 27, 32, 741 P2d 501 (1987) (the word “torture” connotes that the infliction of pain is a reason for the defendant’s intentional act).
Throughout the nineteenth century, state and federal courts interpreted cruel and unusual punishments clauses narrowly and generally prohibited only physically torturous punishments ordered by sentencing judges. For the first half of the twentieth century, claims under Article I, section 16, focused on the duration of the sentence imposed, rather than on the conditions of confinement or alleged deprivations of other constitutional rights.9 Federal courts also [177]*177adhered to a hands-off policy in regard to prisoners’ complaints about conditions of confinement or deprivation of rights by state and local prison officials. Two primary reasons were advanced for this policy: (1) deference to prison officials, the supposed experts in penology, and (2) principles of federalism, which vested primary responsibility for the administration of state prisons in state officials. To this day, federal courts continue to adhere to a policy of deference to a large extent. See Linda G. Hemphill, Challenging Conditions of Confinement: A State Constitutional Approach, 20 Willamette L Rev 409, 413-14 (1984) (explaining federal courts’ policy of deference to state prison officials).
Interpretations of the “cruel and unusual punishments” clause and habeas corpus jurisprudence have evolved, however, so that now a prisoner may challenge circumstances that do not reach the severity of “a lingering death” or “barbarity.” See, e.g., ORS 34.362 (authorizing challenges on ground of conditions of confinement or deprivation of rights while confined); Bedell v. Schiedler, 307 Or 562, 770 P2d 909 (1989) (challenging conditions of confinement); Penrod/Brown v. Cupp, 283 Or 21, 581 P2d 934 (1978) (pre-ORS 34.362: habeas corpus is available to challenge alleged deprivations of prisoners’ rights); see also Eric Neisser, Is There A Doctor In The Joint? The Search For Constitutional Standards For Prison Health Care, 63 Va L Rev 921, 923-36 (1977) (discussing the evolution of judicial standards for prison health care); Michael A. Millemann, Protected Inmate Liberties: A Case for Judicial Responsibility, 53 Or L Rev 29, 50-52 (1974) (recommending that the Eighth Amendment be interpreted to play a central role in the abolition of “intolerable contemporary prison practices”).
In Estelle, the United States Supreme Court stated that the Eighth Amendment now embodies broad and idealistic concepts of dignity, civilized standards, humanity, and [178]*178decency, against which we must evaluate penal measures. 429 US at 102.10
“Thus, we have held repugnant to the Eighth Amendment punishments which are incompatible with ‘the evolving standards of decency that mark the progress of a maturing society/ * * * or which ‘involve the unnecessary and wanton infliction of pain.’ ” Id. at 102-03 (citations omitted).
Notwithstanding that evolution, the phrase “cruel and unusual punishments” still connotes a conscious choice on the part of prison officials to inflict punishment on an inmate. See Black’s Law Dictionary, 1234 (6th ed 1990) (defining “punishments”). The reference in Article I, section 16, to punishments that are “inflicted” also suggests that the punisher must have some level of intent or purpose.
CASE LAW
In Bedell, the plaintiff alleged that the environment in which she was confined subjected her to serious health hazards in violation of the cruel and unusual punishments clause of Article I, section 16. This court stated:
“Plaintiffs replication alleges sufficient specific facts supporting her claim that the conditions of her confinement violate her constitutional rights. Construed liberally, the replication alleges that the environment in which she is confined unnecessarily subjects her to serious health hazards. If prisoners are entitled to reasonable and necessary medical care, it reasonably follows that they also are entitled to an environment that does not unnecessarily subject them to serious health hazards.
“In this case, we do not decide whether plaintiffs evidence will support her claim for habeas corpus relief. Construing her replication liberally and accepting her unchallenged allegations as true, we conclude that she has established her right to a hearing at which she will have a full and fair opportunity to present her evidence. It is simply too early in the judicial process to dismiss this action which raises a claim that is not wholly unsubstantial.” Bedell, 307 Or at 570 (emphasis added; footnote omitted).
[179]*179In Bedell this court did not adopt a “reasonably available” standard. First, this court’s discussion of a standard in Bedell was qualified by the word “[i]f.” Second, the reference to “reasonable and necessary medical care” in Bedell recognized that prison officials have some constitutional duty to provide medical care to inmates, and that that duty is analogous to the duty that was recognized in Estelle— to protect inmates from known serious health hazards. Estelle, 429 US at 103-04. That reference, however, did not identify a definitive minimum standard of medical care that prison officials must provide inmates under Article I, section 16. In fact, Bedell was concerned only with the prison environment, not with medical care per se. Bedell, 307 Or at 564. Bedell was not a rejection of the Estelle standard. Rather, it was this court’s attempt to follow that standard in a different context. Bedell did not even cite Article I, section 16, or Priest. Instead, this court cited Article I, section 13 (the prohibition against treatment with “unnecessary rigor”), and Sterling v. Cupp, 290 Or 611, 625 P2d 123 (1981), a case decided under Article I, section 13.
As we read it, the Court of Appeals’ decision in this case recognizes a more generous substantive standard for obtaining habeas corpus relief in a medical treatment case under the Oregon Constitution than is recognized under the Eighth Amendment after Estelle. For nearly 20 years, the Court of Appeals has adhered to its analysis in Priest. Billings, 133 Or App at 242. Our review of Priest, however, indicates that, as was customary at the time, the Priest court did not engage in any separate state constitutional analysis before announcing its “reasonably available” standard. Priest, 24 Or App at 431. Likewise, the relevant Court of Appeals’ decisions after Priest have not advanced a principled argument for that standard. Rather, they simply have cited or quoted Priest. Moreover, the plaintiff in Priest brought his claim under the Eighth Amendment. The holding in Priest — that the plaintiff failed to prove that the medical care he had received was inadequate — did not turn on the selection of a standard. Additionally, Priest was decided before Estelle.11 Before Estelle, the United States Supreme [180]*180Court had not articulated a standard under the Eighth Amendment for evaluating medical care claims. Priest purported to identify the standard for medical care under the Eighth Amendment and Article I, section 16, and to use the same standard under both constitutions.
HISTORY
We next consider the history of the cruel and unusual punishments clause of Article I, section 16. That clause was modeled after Article I, section 16, of the Indiana Constitution of 1851. See W.C. Palmer, The Sources of the Oregon Constitution, 5 Or L Rev 200, 201 (1925-26) (Article I, section 16, was taken from Article I, sections 16 and 19, of the Indiana Constitution of 1851). Apparently, the Oregon Constitutional Convention passed the clause without recorded discussion. The only available account of the Constitutional Convention debates of 1857 relies exclusively on newspaper reports. Charles A. Carey, ed., The Oregon Constitution and Proceedings and Debates of the Constitutional Convention of 1857, 310 (1926). We find nothing in the history of the “cruel and unusual punishments” clause of Article I, section 16, that suggests that it affords more protection in this context than does the Eighth Amendment.12
OTHER SOURCES
Although stressing the importance of expounding principles of state constitutional analysis, this court also
“has high respect for the opinions of the [United States] Supreme Court, particularly when they provide insight into the origins of provisions common to the state and federal bills of rights rather than only a contemporary ‘balance’ of pragmatic considerations about which reasonable people may differ over time and among the several states.” Kennedy, 295 Or at 267.
This court’s decision in this case is grounded solely on state constitutional principles. Notwithstanding, we find elements of the Supreme Court’s opinion in Estelle persuasive in interpreting Article I, section 16, in this context.13
[181]*181In Estelle, the plaintiff brought a civil rights action under 42 USC § 1983, claiming that the prison’s allegedly inadequate treatment of his back injury constituted cruel and unusual punishment. The district court dismissed the plaintiffs complaint at the pleading stage. The United States Supreme Court held that the government has an obligation to provide medical care for those whom it is punishing by incarceration and that “deliberate indifference to serious medical needs of prisoners constitutes the ‘unnecessary and wanton infliction of pain,’ * * * proscribed by the Eighth Amendment.” Estelle, 429 US at 104.
“Regardless of how evidenced, deliberate indifference to a prisoner’s serious illness or injury states a cause of action under § 1983.” Id. at 105.
See Delker v. Maass, 843 F Supp 1390 (D Or 1994) (applying “deliberate indifference” standard in context of Oregon prisoner’s federal civil rights action against chief medical officer of state penitentiary). An accidental or inadvertent failure to provide adequate medical care would not constitute an “unnecessary and wanton infliction of pain.” Estelle, 429 US at 105. “It is only [deliberate] indifference that can offend ‘evolving standards of decency’ in violation of Eighth Amendment.” Id. at 106. See Wilson v. Seiter, 501 US 294, 111 S Ct 2321, 115 L Ed 2d 271 (1991) (mere negligence does not satisfy “deliberate indifference” standard).14
The Supreme Court held that Estelle’s complaint did not allege an Eighth Amendment violation. Estelle, 429 US at 107. At most, he had stated a claim for medical malpractice that could be pursued in state court under the state tort claims act.
[182]*182To state a cognizable Eighth Amendment claim under Estelle, “a prisoner must allege acts or omissions sufficiently harmful to evidence deliberate indifference to serious medical needs.” Id. at 106. Such a claim involves both an objective and a subjective element. See Delker, 843 F Supp at 1398 (interpreting Estelle). The objective element requires proof that the prisoner has a serious medical need that has not been treated in a timely and proper manner. The subjective element requires proof of “deliberate indifference” to the prisoner’s serious medical need on the part of prison officials. Estelle, 429 US at 106.15
After considering the analysis in Estelle and its progeny, and having given due consideration to the briefs and arguments of counsel in this case, we conclude that the Court of Appeals’ “reasonably available” standard first announced in Priest employs the wrong standard for habeas corpus medical care claims under Article I, section 16. First, the objective element, the seriousness of the plaintiff’s medical condition, is absent ffom the Court of Appeals’ test. By posing only the question of what treatment is reasonably available for a given condition, that standard may give constitutional significance to minor complaints about prisoners’ medical care. That matters, because Article I, section 16, is only meant to prevent “cruel and unusual” punishments, not merely annoying, negligent or unpleasant punishments. The words and history of the clause set a high objective standard. Second, the subjective element, deliberate indifference on the part of prison officials, also is absent from the Court of Appeals’ test. As noted, that subjective element derives from the concepts of “inflicting” and “punishment.” Again, even if conduct (or a failure to act) causes pain or suffering, Article I, section 16, forbids it only if it is a form of punishment that is “inflicted,” that is to say — it is not the result of a happenstance or even negligence. Estelle, 429 US at 105-06.
We hold that the Eighth Amendment’s “deliberate indifference to serious medical needs” standard is the appropriate standard under Article I, section 16. To state a cognizable claim for habeas corpus relief under Article I, section [183]*18316, a prisoner must allege that the prisoner has a serious medical need that has not been treated in a timely and proper manner and that prison officials have been deliberately indifferent to the prisoner’s serious medical needs. Id., at 106.
Deliberate indifference to serious medical needs of prisoners constitutes the unnecessary and wanton infliction of pain, whether the indifference is manifested by prison doctors in their response to a prisoner’s serious medical needs or by prison guards in intentionally denying or delaying access to medical care, or in intentionally interfering with prescribed treatment. Id. at 104-05. The “deliberate indifference” standard is not intended to insulate prison staff from judicial scrutiny of decisions made in the course of diagnosing and treating prison inmates. But, for the reasons explained above, it is true that an inmate ultimately will fail to prove an Article I, section 16, violation if the inmate establishes nothing more than an honest difference of medical opinion about correct diagnosis and necessary treatment. See Estelle, 429 US at 105-06 (so stating with regard to Eighth Amendment); Sanchez v. Vild, 891 F2d 240, 242 (9th Cir 1989). The inmate plaintiff also must establish the existence of a “serious” medical condition. A medical condition is serious when, if untreated, it would have a significant adverse effect on an inmate’s daily activities, resulting in substantial and recurring pain or discomfort, or would create a significant risk of permanent disability or death. See McGuckin v. Smith, 974 F2d 1050, 1059-60 (9th Cir 1992) (“A ‘serious’ medical need exists if the failure to treat a prisoner’s condition could result in further significant injury or the ‘unnecessary and wanton infliction of pain.’ ”); Delker, 843 F Supp at 1398-99 (the presence of a medical condition that significantly affects an individual’s daily activities, or the existence of chronic and substantial pain are indicators that a prisoner has a “serious” need for medical treatment).16
Having articulated the correct standard under Article I, section 16, we proceed to examine plaintiffs petition to determine whether he has stated sufficient facts to state a [184]*184claim, ORS 34.680, and to avoid the denial of his petition as being “meritless,” ORS 34.370(2)(b)(A). In doing so, we take the allegations of the petition as true and give plaintiff the benefit of all favorable inferences that may be drawn therefrom. ORS 34.370(7); Bedell, 307 Or at 566 (pre-ORS 34.370(7)).
Plaintiffs petition alleges that SRCI’s doctor told him that he has high arches, that the shoes provided by SRCI have no arch supports, and that without arch supports “any walking causes [plaintiff] pain to the point where he cannot walk.” His petition further alleges that arch supports are available from SRCI’s commissary, but that he is indigent and, therefore, unable to purchase them. Last, he alleges that SRCI knows that he is indigent and, yet, will not provide him with arch supports. Thus, plaintiff asserts, defendant is denying him “proper” medical care.17
We conclude that plaintiffs petition states a claim of deliberate indifference by prison officials to his serious medical needs, sufficient to defeat defendant’s motion to dismiss under ORS 34.680. Accordingly, we hold that the trial court erred in dismissing plaintiffs petition.
We do not decide, of course, whether the evidence eventually will support a claim for habeas corpus relief.18 As in Bedell, we hold only that this petition should not have been denied on the basis of the pleadings alone.
The decision of the Court of Appeals is affirmed on different grounds. The judgment of the circuit court is [185]*185vacated, and the case is remanded to the circuit court for further proceedings.
