Appellee Vladimir Collazo-León, a pretrial detainee at the Metropolitan Detention Center at Guaynabo, Puerto Rico, brought a habeas corpus action alleging that he had been denied both substantive and procedural due process by the United States Bureau of Prisons (BOP) when he was placed in disciplinary segregation for ninety days and had his telephone and visitation privileges taken away for six months as punishment for misconduct. After being placed in segregation, Collazo-León applied for a writ of habeas corpus which the magistrate judge recommended that the court deny. The district court disagreed and granted the petition finding that the practice violated substantive due process of law. The BOP appeals the district court’s grant of a writ of habeas corpus to Collazo-León.

FACTS

Collazo-León was named in eleven counts of a thirteen-count indictment, returned in the District of Puerto Rico, charging conspiracy to import and distribute cocaine. On April 7, 1994, while being held in pretrial detention, Collazo-León appeared before a disciplinary hearing officer (DHO), was informed of disciplinary charges against him, and, based upon an affidavit, was found to have attempted escape and to have offered a bribe to a prison guard to induce his assistance in Defendant’s escape attempt. The charges for both acts arise out of the same set of facts: Collazo-León offered a prison guard one million dollars to get him “to the avenue.” The sanction imposed by the DHO for the attempted escape was sixty days of segregation and the loss of visiting privileges for six months. The sanction imposed by the DHO for the offer of a bribe was thirty days segregation and the loss of telephone privileges for six months. ^[1]

Collazo-León was placed in segregation and applied for a writ of habeas corpus, charging a denial of both substantive and procedural due process. 28 U.S.C. § 2255. The magistrate judge found that Collazo-León had been afforded procedural due process and that the practice of placing a pretrial detainee in disciplinary segregation, and taking away his telephone and visitation privileges as punishment for misconduct, was permissible under the circumstances. Accordingly, the magistrate judge recommended that the district court deny the writ of habeas corpus. Despite this recommendation, the district court granted the writ, permitting Collazo-León’s return to the general prison population before the end of his ninety-day segregation.

The district court did not address the magistrate judge’s finding on Collazo-León’s claim for denial of procedural due process. Instead, the court directed all its attention to the substantive violation finding that the ex[*317] press intent of the prison regulation authorizing segregation was “punishment,” 28 C.F.R. § 541.20(a), ^[2] and that “less drastic resources were not considered” as alternatives to the segregation and loss of privileges. The court concluded that the disciplinary action taken amounted to impermissible punishment and served no legitimate regulatory purpose in the effective management of the correctional institution. Thereafter, the district court denied the BOP’s motion for reconsideration. The.BOP now appeals the district court’s decision.

DISCUSSION

The BOP argues that the district court expanded the principle established by the Supreme Court in Bell v. Wolfish, 441 U.S. 520, 99 S.Ct. 1861, 60 L.Ed.2d 447 (1979), and created a rule that the Constitution prohibits the discipline of pretrial detainees. Collazo-León responds that the district court correctly found that the Constitution prohibits disciplining pretrial detainees who violate prison rules in the manner imposed here because doing so amounts to impermissible punishment. ^[3] To a great extent, both parties’ arguments are built on semantics: labeling the action as either permissible discipline or impermissible punishment. This Court, however, does not find that there is any meaningful distinction between the terms “punishment” and “discipline” in this case.

In Bell v. Wolfish, 441 U.S. 520, 99 S.Ct. 1861, the Supreme Court examined some aspects of the constitutional rights of pretrial detainees. Bell teaches that punishment cannot be inflicted upon pretrial detainees prior to an adjudication of guilt in accordance with due process of law. The inquiry, however, does not end with the designation of a condition of confinement as “punishment.” To distinguish between impermissible and permissible measures, the Bell Court stated:

A court must decide whether the disability is imposed for the purpose of punishment or whether it is but an incident of some other legitimate governmental purpose. See Flemming v. Nestor, [363 U.S. 603,] at 613 — 617[, 80 S.Ct. 1367, 1373-76, 4 L.Ed.2d 1435].... [I]f a particular condition or restriction of pretrial detention is reasonably related to a legitimate governmental objective, it does not, without more, amount to “punishment.” Conversely, if a' restriction or condition is not reasonably related to a legitimate goal — if it is arbitrary or purposeless — a court permissibly may infer that the purpose of the governmental action is punishment that may not constitutionally be inflicted upon detainees qua detainees.

Id. at 538-39, 99 S.Ct. at 1873-74 (footnotes omitted).

Bell was a class action seeking injunctive relief and challenging various general conditions, practices, and policies to which all pretrial detainees were subjected, including double-bunking, strip-searches, and various other security measures. The conditions imposed on the pretrial detainees in Bell involved no direct or individualized disciplinary or deterrent purpose. Here, by contrast, the segregation and loss of privileges are directly related to the exercise of the prison staffs disciplinary authority by both punishing Col-lazo-León for his institutional misconduct and deterring him from engaging in it in the future. In Bell, the Court was not faced with the situation where discrete sanctions were imposed on individual pretrial detainees as discipline for specific in-house violations. Although factually distinguishable, the theoreti[*318] cal constitutional premises of Bell’s analysis provides some rational guidance in this case.

On the authority of Bell, it may be divined that even if a restriction or condition may be viewed as having a punitive effect on the pretrial detainee, it is nonetheless constitutional if it also furthers some legitimate governmental objective such as addressing a specific institutional violation and is not excessive in light of the seriousness of the violation. Bell, 441 U.S. at 538-39, 99 S.Ct. at 1873-74; Youngberg v. Romeo, 457 U.S. 307, 320, 102 S.Ct. 2452, 2460, 73 L.Ed.2d 28 (1982) (requiring that restrictions on the liberty of an involuntarily confined mental patient be reasonably related to legitimate government interests in imposing those restrictions). Among the legitimate objectives recognized by the Supreme Court are ensuring a detainee’s presence at trial and maintaining safety, internal order, and security within the institution. Bell, 441 U.S. at 540, 99 S.Ct. at 1874. If there is a reasonable relation between the sanctions and legitimate institutional policies, an intent to punish the detainee for prior unproven criminal conduct cannot be inferred. Accordingly, this Court must determine whether the punishment imposed here was incident to some legitimate governmental purpose.

In this case, the district court looked at whether the sanction imposed on Collazo-León was of a “punitive” character. The court found it to be punitive, reasoning that because after Collazo-León serves his time in segregation, he will present “the same risk of flight and the same security hazard that he did when [the BOP] determined that his conduct justified placing him in isolation,” the discipline did not serve the BOP’s legitimate goal of providing a safe and orderly environment for inmates. This Court finds that statement by the district court particularly curious. Although Collazo-León may continue to be a risk to security after release from segregation that does not mean that legitimate governmental goals are not served by the disciplinary action. If the district court’s statement regarding Collazo-León’s continued security risk is taken to its logical conclusion, any type of discipline imposed would not be allowable because Collazo-León must, inevitably, be returned to the general prison population. This overlooks entirely any reasonable expectation that the discipline will have a deterrent effect on the Defendant.

The administrators of the prison must be free, within appropriate limits, to sanction the prison’s pretrial detainees for infractions of reasonable prison regulations that address concerns of safety and security within the detention environment. The district court found that the severity of the sanction on the pretrial detainee for “whom no attempt is made to deal with his disciplinary problem by means of less drastic actions, compel[s] the conclusion that the purpose in segregating is to punish.” We agree that the measure is punishment, but we disagree that it is improper under the circumstances of this case. The Supreme Court has warned that when

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.’

Id. at 540-41 n. 23, 99 S.Ct. at 1874-75 n. 23 (quoting Pell v. Procunier, 417 U.S. 817, 827, 94 S.Ct. 2800, 2806, 41 L.Ed.2d 495 (1974)). This recognition is a clear approval of a broad exercise of discretion by prison authorities to take reasonable and necessary action, including punishment, to enforce the prison disciplinary regime and to deter even pretrial detainees from violation of its requirements. What the Constitution prohibits is the undue expansion of the exercise of such authority for the purpose, or with the unintended effect, of punishing the pretrial detainee for the acts that are the basis for his prosecution and his consequent pretrial detention. In other words, reasonable punishment may be imposed to enforce reasonable prison disciplinary requirements but may not be imposed to sanction prior unproven criminal conduct. Recognizing the need to accord prison officials considerable latitude in matters of internal discipline, we will not interfere with the execution of reasonable means,[*319] such as the internal discipline effort involved here, adopted by the BOP to achieve a legitimate governmental objective. We cannot say that the sanctions imposed, in light of the seriousness of the violations, were so extreme as to be unreasonable by the constitutional standard.

For the reasons discussed above, the district court’s grant of the writ of habeas corpus on the substantive due process grounds is VACATED. The case is REMANDED to the district court to determine whether Col-lazo-León’s right to procedural due process was violated. ^[4]
