Pro se plaintiff Josephine Brown appeals the summary judgment order of the district court dismissing his 42 U.S.C. § 1983 civil rights action. 1 We have jurisdiction pursuant to 28 U.S.C. § 1291 and remand to the district court for further proceedings consistent with this opinion.
I. BACKGROUND
Mr. Brown is an inmate at the Limón Correctional Facility, a Colorado state prison. In his complaint against two corrections officials, Mr. Brown states that he is a trans
*969
sexual. The medical term for transsexuality is “gender dysphoria,” and gender dysphoria is a medically recognized psychological disorder resulting from the “disjunction between sexual identity and sexual organs.”
Farmer v. Haas,
Mr. Brown alleged in his complaint that the defendants have violated his Eighth Amendment right to be free from cruel and unusual punishment and his Fourteenth Amendment equal protection rights. Specifically, he alleged that defendants have withheld medical care with deliberate indifference to his serious medical needs by not providing him with the female hormone estrogen and other medical treatment in contravention of the rule in
Estelle v. Gamble,
After reviewing the complaint, a federal magistrate issued a show cause order stating that he would dismiss the complaint if Mr. Brown did not explain how the defendants personally participated in the alleged constitutional violations and why Mr. Brown felt he was entitled to hormone treatment. Mr. Brown responded that the named defendants were involved in his § 1983 claim, that he was entitled to hormone treatment and “therapy,” and that he had an equal protection right to hormone therapy. Rec. vol. I, doc. 5, at 2.
Defendants then filed a motion to dismiss, attaching the Department of Corrections grievance process forms to the motion. Mr. Brown responded to the motion to dismiss with a further explanation of his action. After reviewing the motion and the materials outside the pleadings, the magistrate converted the motion to dismiss into a summary judgment proceeding pursuant to Fed. R.Civ.P. 12(b). The magistrate recommended that Mr. Brown’s Eighth Amendment claim be dismissed because Mr. Brown had alleged only that Colorado had failed to -provide estrogen treatment.
In his response to the magistrate’s recommendation, Mr. Brown asserted that “[tjhere has been a total failure by the defendants to provide any kind of medical attention to the plaintiff for his transsexual condition,” and argued that the magistrate had not addressed his equal protection argument. Rec. vol. I, doc. 14, at 3. The district court accepted the magistrate’s recommendation regarding the Eighth Amendment claim. The district court further noted that Mr. Brown was not a member of a “protected class” and dismissed the equal protection claim. On appeal, Mr. Brown argues that the district court erred in dismissing both his Eighth Amendment and Equal Protection claims.
II. DISCUSSION
A. Summary Judgment Conversion
We begin by noting that it appears that the magistrate made a procedural mistake in this case by not notifying Mr. Brown that the magistrate was converting the motion to dismiss into a summary judgment motion. A court may convert a Rule 12(b)(6) motion to dismiss into a summary judgment proceeding in order to consider matters outside of the plaintiffs complaint.
Jackson v. Integra Inc.,
In this case, the magistrate relied upon matters outside of the complaint. However, there is no indication in the record that the court notified Mr. Brown of the conversion to a summary judgment proceeding or that he had the opportunity to introduce evidence *970 supporting his claims. We therefore will not review the district court’s grant of summary judgment.
Nevertheless, a district court’s failure to comply with Rule 56 is harmless if the dismissal can be justified under Rule 12(b)(6) without reference to matters outside of the plaintiffs complaint.
Miller,
B. Eighth Amendment
Mr. Brown argues that the defendants have provided inadequate medical care under the Eighth Amendment. Deliberate indifference by prison officials to a prisoner’s serious medical need constitutes cruel and unusual punishment in violation of the Eighth Amendment.
Estelle,
This circuit was one of the first to consider whether transsexuals had an Eighth Amendment right to estrogen.
See Supre v. Ricketts,
The defendants’ sole response to Mr. Brown’s Eighth Amendment claim is that Mr. Brown failed to raise the issue in the district court. In light of our obligation to construe pro se pleadings liberally,
see Haines v. Kerner,
We therefore remand to the district court to properly determine whether Mr. Brown is being offered medical care consistent with Supre.
C. Equal Protection
Mr. Brown also asserts that he is being denied the equal protection of the laws because some prisoners receive estrogen treatment. 4 In this case, the district court *971 observed that transsexuals are not a protected class and dismissed Mr. Brown’s equal protection claim.
The Ninth Circuit has held that transsexuals are not a protected class.
Holloway v. Arthur Andersen & Co.,
Recent research concluding that sexual identity may be biological suggests reevaluating
Holloway. See Equality Found, v. City of Cincinnati,
Competing standards for resolving a plaintiffs equal protection claim under Rule 12 complicate our analysis when we review a plaintiffs claim under the rational basis standard. In
Wroblewski v. City of Washburn,
A perplexing situation is presented when the rational basis standard meets the standard applied to a dismissal under Fed R.Civ.P. 12(b)(6). The rational basis standard requires the government to win if any set of facts reasonably may be conceived to justify its classification; the Rule 12(b)(6) standard requires the plaintiff to prevail if “relief could be granted under any set of facts that could be proved consistent with the allegations.” Hishon v. King & Spalding,467 U.S. 69 , 73,104 S.Ct. 2229 , 2232-33,81 L.Ed.2d 59 (1984). The rational basis standard, of course, cannot defeat the plaintiffs benefit of the broad Rule 12(b)(6) standard. The latter standard is procedural, and simply allows the plaintiff to progress beyond the pleadings and obtain discovery, while the rational basis standard is the substantive burden that the plaintiff will ultimately have to meet to prevail on an equal protection claim.
Id. at 459-60. The court then adopted a hybrid approach to reconcile the standards, holding that a plaintiff pursuing an equal protection claim must allege facts sufficient to overcome a presumption of government rationality.
"While we therefore must take as true all of the complaint’s allegations and reasonable inferences that follow, we apply the resulting “facts” in light of the deferential rational basis standard. To survive a motion to dismiss for failure to state a claim, a plaintiff must allege facts sufficient to overcome the presumption of rationality that applies to government classifications.
Id.
at 460. Finally, the
Wroblewski
court reviewed possible government rationales for the actions at issue, noted that a court must presume that government actions are rational, and held that the plaintiffs “conclusionary assertions” were insufficient to state a claim under that standard.
Id.; see also Shanks v. Forsyth County Park Auth., Inc.,
It is a close question as to whether Mr. Brown’s complaint raises an equal protection claim under the
Wroblewski
standard.
See Wroblewski,
We REVERSE and REMAND this matter to the district court for proceedings consistent with this opinion regarding Mr. Brown’s Eighth Amendment claim, but AFFIRM the decision of the district court regarding Mr. Brown’s equal protection claim.
Notes
. Although plaintiff identifies his true gender as female, plaintiff is biologically male and refers to himself with masculine pronouns throughout his pleadings. As is our practice, we refer to litigants as the record suggests they prefer to be addressed.
.However, in addressing the Eighth Amendment claim of a preoperative transsexual who had taken estrogen before entering prison, the United States District Court for the Western District of Michigan has issued a preliminary injunction ordering prison officials to provide female hormones to the prisoner.
Phillips v. Michigan Dep't of Corrections,
Unlike the plaintiff in Phillips, however, Mr. Brown has not alleged that he received hormone treatment for gender dysphoria prior to his incarceration. Phillips is therefore inapplicable to this case.
. Although the documents defendants attached to their motion to dismiss suggest that it is the policy of the Colorado Department of Corrections to provide preoperative transsexual prisoners who have not taken hormones with counseling rather than hormones, we review Mr. Brown’s claim under the Rule 12 standard, referring only to his complaint.
. The documents that defendants attached to their motion to dismiss suggest that Colorado provides hormones to prisoners with low hormone levels and that the state will therefore give estrogen to postoperative transsexuals who suffer from a hormone imbalance. However, as we have noted, we review Mr. Brown's claim under the Rule 12 standard, referring only to his complaint.
