What rights can a civil detainee claim in conditions of confinement?

Certain rights of detainees, like those of convicted prisoners, "may be limited or retracted if required to 'maintain institutional security and preserve internal order and discipline.'" Pierce v. County of Orange, 526 F.3d 1190, 1209 (9th Cir. 2008). However, a civil detainee "cannot be subjected to conditions that 'amount to punishment.'" Jones v. Blanas, 393 F.3d 918, 931-32 (9th Cir. 2004) (explaining that conditions of confinement claims brought by civil detainees are evaluated under the "more protective" Fourteenth Amendment substantive due process standard, and that civil detainees are entitled to less restrictive treatment than criminally convicted prisoners) (quoting Bell v. Wolfish, 441 U.S. 520, 535 (1979)).
