OPINION OF THE COURT
Three detainees in the Delaware Correctional System — David Stevenson, Michael Manley, and Michael L. Jones — filed an action under 42 U.S.C. § 1983 against Warden Thomas Carroll, alleging violations of their substantive and procedural due process rights. The District Court dismissed their complaint. On appeal, they assert that their allegations of placement in restrictive confinement state valid substantive and procedural due process claims sufficient to survive a motion to dismiss. We agree, and remand the case to the District Court.
I.
At the time of their complaint, Stevenson and Manley were awaiting resentenc-ing. Both had been convicted and sentenced to death in January 1997, but their sentences were vacated and remanded on or about May 30, 2001. At that time, they were moved off death row, and into the Security Housing Unit (“SHU”). Stevenson was moved from the SHU to a less restrictive pre-trial facility in December 2003, but was returned to the SHU in January 2004. Neither one of them received a hearing or explanation for their *65 transfers into the SHU. They were both subsequently re-sentenced to death on February 3, 2006.
Jones was awaiting trial at the time of the complaint. Following a disruption at Gander Hill Prison in Wilmington, Delaware, he and several other inmates were moved to the SHU on or about February 19, 2003. Jones asserts that, like Stevenson and Manley, he was not afforded an explanation or hearing regarding his transfer into more restrictive housing. He does, however, state that he was alleged to have been involved in the riot at Gander Hill. Jones was subsequently found guilty of first-degree' murder and sentenced to life imprisonment on September 16, 2005.
The appellants seek relief in the form of a transfer back into the general prison population, monetary damages, arid the establishment of a system of review for transfers of pretrial detainees into the SHU. 1
The Warden filed a motion to' dismiss under Federal Rule of Civil Procedure 12(b)(6), which was granted on December 7, 2004. The District Court held that the detainees’ transfer out of the general prison population into the SHU for nonpunitive reasons was within the scope of the prison officials’ authority with respect to prison management. In its ruling, the District Court relied upon
Sandin v. Conner,
II.
Stevenson, Manley, and Jones present two arguments as to why their complaint should have survived the motion to dismiss. First, they argue that they have sufficiently asserted a liberty interest in being free from punishment prior to imposition of sentence. Second, they assert that they should have been afforded notice of their transfer and an opportunity to respond. The Warden disputes the sufficiency of their substantive and procedural due process claims, arguing that they have made only conclusory allegations regarding punishment and have no cognizable liberty interest in being housed in the general prison population.
In support of his. contention that the complaint made only conclusory statements regarding punishment, the Warden looks to
Evancho v. Fisher,
To be sure, there are reasonable inferences apart from punishment that could be drawn from the complaint as explanation for the appellants’ confinement. Jones notes that he was alleged to have been a participant in a riot at the Gander Hill detention facility. If this allegation is true, it is entirely possible that his relocation to the Smyrna facility’s SHU was for disciplinary reasons rather than for impermissible retaliation or punishment. Likewise, Stevenson and Manley admit that they had been sentenced to death, but that only their sentences had been vacated. Death sentences are available in Delaware only for offenses of first-degree murder.
See
11 Del. Code §§ 636, 4209(a). Accordingly, the Warden’s assertion that Stevenson and Manley were housed in the SHU because they were charged with violent offenses is also a legitimate inference to be drawn from the complaint. However, the fact that such inferences may be drawn is proof that the dismissal was premature. The appellants have met their obligation to provide grounds for their entitlement to relief by presenting factual allegations sufficient to raise their right to relief above a speculative level.
See, e.g., Bell Atlantic Corp. v. Twombly,
— U.S. -,
The complaint also alleges sufficient facts to make out a claim for relief based on procedural due process. In addition to the list of deprivations the plaintiffs suffered, the complaint states that they were not afforded “all the rights of normal pretrial [detainees],” and that the “standard practice at Delaware Correctional Center” of returning those whose sentences had been vacated to the general prison population was not followed. These allegations do not explicitly state the nature of the appellants’ alleged liberty interest, but they provide an adequate framework for the inquiry.
See, e.g., Unger v. Nat’l Residents Matching Program,
The complaint details the differences between the conditions they encountered in the SHU and those encountered by regular pretrial detainees. It evinces the appellants’ contention that they were improperly housed in the SHU without explanation or an opportunity to contest their placement. The complaint states that the appellants wrote to Warden Carroll and his employees requesting an explanation for their confinement in the SHU, but received no response. The reasonable inference to be drawn from these allegations is that the appellants assert a liberty interest in being free from punishment while awaiting sentencing and in not being held in the SHU indefinitely. The plaintiffs specifically requested relief in the form of “a system to inform inmates why they were put into isolation, who made the decision to put them in isolation, *67 and a chance to appeal the decision to a non-partisan official.” They also requested that the prison “[m]ake procedural safeguards.” The allegations in the complaint sufficiently raise the appellants’ claim that their procedural due process rights were violated.
III.
A.
Although both Stevenson and Manley had been convicted at the time of their complaint, they are classified as pretrial detainees for purposes of our constitutional inquiry.
See Cobb v. Aytch,
B.
With respect to the substantive due process claims of punishment, in
Bell v. Wolfish,
the Supreme Court established the principle that “under the Due Process Clause, a detainee may not be punished prior to an adjudication of guilt in accordance with due process of law.”
Whether the sanction involves an affirmative disability or restraint, whether it has historically been regarded as a punishment, whether it comes into play only on a finding of scienter, whether its operation will promote the traditional aims of punishment—retribution and deterrence, whether the behavior to which it applies is already a crime, whether an alternative purpose to which it may rationally be connected is assignable for it, and whether it appears excessive in relation to the alternative purpose assigned áre all relevant to the inquiry....
See also Bell,
Unconstitutional punishment typically includes both objective and subjective components. As the Supreme Court explained in
Wilson v. Seiter,
[A] particular measure amounts to punishment when there is a showing of express intent to punish on the part of detention facility officials, when the restriction or condition is not rationally related to a legitimate non-punitive government purpose, or when the restriction is excessive in light of that purpose.
Because the District Court could not make either an objective inquiry into the severity of the deprivations or a subjective inquiry into the mental state of the officials at the motion to dismiss stage, the dismissal was improper. One reasonable inference from the allegations in the complaint of disparate treatment of prisoners is that, at a minimum, the appellants’ confinement in the SHU was arbitrary.
See id.
at 304,
In evaluating a pretrial detainee’s claim of unconstitutional punishment, courts must examine the totality of the circumstances within the institution. In
Hubbard v. Taylor,
When warranted, such discovery need not be extensive. In situations such as this, where the allegations of punishment are coextensive with the allegations that form the basis for the procedural due process claim, it will generally be sufficient for the prison officials to submit affidavits to show that the classification was appropriate based on reasonable prison management concerns. While district courts have discretion to manage their cases, such affidavits alone will often be adequate to resolve the punishment inquiry. Although the substantive and procedural due process evaluations are distinct, a showing by the prison officials that a restrictive housing assignment is predicated on a legitimate managerial concern and is therefore not arbitrary or purposeless, will typically foreclose the substantive due process inquiry.
C.
Appellants assert that they were denied notice of their transfer and an opportunity to respond. The Supreme Court has repeatedly stated that “[t]he core of due process is the right to notice and a meaningful opportunity to be heard.”
LaChance v. Erickson,
*70
In determining what procedural protections are adequate, we are guided by the tenet that “[d]ue process is flexible and calls for such procedural protections as the particular situation demands. Accordingly, resolution of the issue whether ... administrative procedures provided ... are constitutionally sufficient requires analysis of the governmental and private interests that are affected.”
Mathews v. Eldridge,
Taking into account both the private interests of the detainees and the governmental function involved, it becomes clear that the process required for administrative transfers of pretrial detainees need not be extensive. Detainees have a liberty interest in not being subjected to punishment for the crime with which they have been charged until after they have been convicted and sentenced, but the governmental interest in maintaining prison security for the duration of their detention is substantial.
Bell v. Wolfish,
Prison officials must provide detainees who are transferred into more restrictive housing for administrative purposes only an explanation of the reason for their transfer as well as an opportunity to respond. This level of process comports with the Supreme Court’s holding in
Hewitt v. Helms,
The degree of process required varies depending on the reason for the transfer, with greater process accorded to prisoners who are confined for disciplinary infractions than those moved for purely administrative reasons.
See Mathews,
Jones’ complaint suggests that his transfer was occasioned by his alleged participation in a prison riot, which may necessitate a higher level of procedure. Stevenson and Manley allege only that they were transferred without explanation. The Warden stated in an affidavit attached to his memorandum in support of the motion to dismiss that Jones’ transfer to the SHU was due to the fact that he had “very serious pending charges” and “a number of inmate disciplinary infractions.” The Warden also stated that Stevenson and Manley were housed in the SHU based on their “potential ... to again receive a sentence of death.” Accordingly, the District Court should examine the asserted purposes for appellants’ detentions, and determine whether sufficient process has been afforded.
In considering the asserted rationale for placing pretrial detainees in restricted housing, courts should be mindful of our pronouncement in
Shoats:
“Shoats could conceivably be held in administrative custody merely because his prior crimes reasonably foreshadow future misconduct.”
Shoats,
In
Bell,
the Supreme Court instructed that if there is a reasonable relationship between the particular condition or restriction of pretrial detention and a legitimate governmental objective, then that condition, “without more,” does not infringe upon a detainee’s constitutional rights.

Warden Carroll asserts that he is entitled to qualified immunity on the grounds that even if the facts alleged show a violation of a constitutional right, that right was not clearly established.
Saucier v. Katz,
V.
Under the liberal construction of complaints afforded to pro se prisoner plain *72 tiffs, we find that the complaint challenges the reasonable relationship of the appellants’ confinement to a legitimate government objective and alleges impermissible punishment of pretrial detainees. The complaint alleges deprivations suffered by the appellants and compares their living conditions to those of the general prison population. The appellants asserted that they had sought, but been refused, an explanation for their placement in the SHU. Accordingly, the complaint alleges sufficient facts to survive the motion to dismiss. We will vacate the dismissal of the complaint and remand the case to the District Court.
Notes
. Stevenson and Manley are now on death row, and Warden Carroll indicates that Jones is now housed in the part of the SHU reserved for sentenced inmates. Accordingly, their request for injunctive relief on the grounds that they are improperly confined pretrial detainees is moot. The other two forms of relief they seek continue to be viable.
. The District Court had subject matter jurisdiction under 28 U.S.C. § 1331. This Court has jurisdiction pursuant to 28 U.S.C. § 1291.
. In a footnote, the Court exhorted that
In determining whether restrictions or conditions are reasonably related to the Government's interest in maintaining security and order and operating the institution in a manageable fashion, courts must heed our warning that "[s]uch considerations are peculiarly within the province and professional expertise of corrections officials, and, in the absence of substantial evidence in the record to indicate that the officials have exaggerated their response to these considerations, courts should ordinarily defer to their expert judgment in such matters."
