allowed any writing or reading material in their cells except the Bible. Furthermore, they are not allowed any physical exercise or recreation; the only time they are allowed out of the isolation cell is for a daily shower”. Id. at 989.
We declined to find that isolation in these circumstances was unconstitutional per se. We found, however, that these conditions substantially curtailed the freedom of juveniles placed in isolation, and thus deserved close scrutiny. Santana v. Collazo, 714 F.2d 1172, 1181 (1st Cir.1983). We noted that while courts have been reluctant to find isolation cells unconstitutional in adult prisons, id. at 1179, juveniles who have not been convicted of crimes have “a due process interest in freedom from unnecessary bodily restraint which entitles them to closer scrutiny of their conditions of confinement than that accorded convicted criminals”. Id. See Youngberg v. Romeo, 457 U.S. 307, 102 S.Ct. 2452, 73 L.Ed.2d 28 (1982) (restrictions on liberty of involuntarily confined mentally-retarded patients must be reasonably related to legitimate government interests). Moreover, because the Commonwealth has no legitimate interest in punishing such juveniles as retribution for past misdeeds (as may be permissible in the case of convicted criminals), restrictions on their liberty must be justified on the basis of other objectives — rehabilitation, safety, or internal order and security. 714 F.2d at 1180.
We recognized, however, that administrators of a juvenile home must be allowed to punish residents for the purpose of discipline. And we conceded that “[t]he distinction between conditions imposed for the legitimate purpose of maintaining institutional order and safety and those that amount to retribution is a fine one.” Id. Yet, in this case, we found that it was a distinction demanding attention.
“Were there nothing of concern in the record, we might be inclined to assume that the state’s interest, presumably in protecting the juveniles from harm, in discouraging offending behavior and in preventing escapes, was sufficient to justify the deprivations imposed. A number of experts testified, however, that isolation for longer than a few hours serves no legitimate therapeutic or disciplinary purpose and is unnecessary to prevent harm unless a juvenile is severely emotionally disturbed. In addition, the experts testified, extended isolation can by psychologically damaging and, under the conditions of Mayaguez, may be physically harmful.” 714 F.2d at 1181.
We thus concluded that, in the light of the record before us, the use of isolation at Mayaguez deserved closer scrutiny than it had thus far been given, and that the district court was best suited to conduct further inquiry.
“[W]e think a remand is necessary for the court to consider, based on the testimony already presented to it and its own examination of conditions at Mayaguez, whether and to what extent isolation as employed [at Mayaguez] is reasonably related to any legitimate government objectives. In doing so, the court should consider whether isolation should be limited to certain time periods and should require additional safeguards, such as close supervision by a qualified expert and periodic review of the continuing need for isolation. Finally, the court should consider whether minimal additional individual attention might reduce the need for isolation____ The district court may be aware of other possibilities that, with minimal additional attention might alleviate the need for extensive use of isolation.” 714 F.2d at 1181-82.
We pointed out that, under Youngberg, the reasonableness of defendants’ practice regarding isolation “should be assessed in light of the judgment of qualified professionals.” Id. 714 F.2d at 1182; Youngberg, 457 U.S. at 323, 102 S.Ct. at 2462.
II.
Two factors seemed to motivate the district court to find that isolation as used at Mayaguez meets constitutional requirements. First, the court pointed to the sub
