18 U.S.C. § 3626 : US Code - Section 3626: Appropriate remedies with respect to prison conditions

      (a) Requirements for Relief. - 
        (1) Prospective relief. - (A) Prospective relief in any civil
      action with respect to prison conditions shall extend no further
      than necessary to correct the violation of the Federal right of a
      particular plaintiff or plaintiffs. The court shall not grant or
      approve any prospective relief unless the court finds that such
      relief is narrowly drawn, extends no further than necessary to
      correct the violation of the Federal right, and is the least
      intrusive means necessary to correct the violation of the Federal
      right. The court shall give substantial weight to any adverse
      impact on public safety or the operation of a criminal justice
      system caused by the relief.
        (B) The court shall not order any prospective relief that
      requires or permits a government official to exceed his or her
      authority under State or local law or otherwise violates State or
      local law, unless - 
          (i) Federal law requires such relief to be ordered in
        violation of State or local law;
          (ii) the relief is necessary to correct the violation of a
        Federal right; and
          (iii) no other relief will correct the violation of the
        Federal right.

        (C) Nothing in this section shall be construed to authorize the
      courts, in exercising their remedial powers, to order the
      construction of prisons or the raising of taxes, or to repeal or
      detract from otherwise applicable limitations on the remedial
      powers of the courts.
        (2) Preliminary injunctive relief. - In any civil action with
      respect to prison conditions, to the extent otherwise authorized
      by law, the court may enter a temporary restraining order or an
      order for preliminary injunctive relief. Preliminary injunctive
      relief must be narrowly drawn, extend no further than necessary
      to correct the harm the court finds requires preliminary relief,
      and be the least intrusive means necessary to correct that harm.
      The court shall give substantial weight to any adverse impact on
      public safety or the operation of a criminal justice system
      caused by the preliminary relief and shall respect the principles
      of comity set out in paragraph (1)(B) in tailoring any
      preliminary relief. Preliminary injunctive relief shall
      automatically expire on the date that is 90 days after its entry,
      unless the court makes the findings required under subsection
      (a)(1) for the entry of prospective relief and makes the order
      final before the expiration of the 90-day period.
        (3) Prisoner release order. - (A) In any civil action with
      respect to prison conditions, no court shall enter a prisoner
      release order unless - 
          (i) a court has previously entered an order for less
        intrusive relief that has failed to remedy the deprivation of
        the Federal right sought to be remedied through the prisoner
        release order; and
          (ii) the defendant has had a reasonable amount of time to
        comply with the previous court orders.

        (B) In any civil action in Federal court with respect to prison
      conditions, a prisoner release order shall be entered only by a
      three-judge court in accordance with section 2284 of title 28, if
      the requirements of subparagraph (E) have been met.
        (C) A party seeking a prisoner release order in Federal court
      shall file with any request for such relief, a request for a
      three-judge court and materials sufficient to demonstrate that
      the requirements of subparagraph (A) have been met.
        (D) If the requirements under subparagraph (A) have been met, a
      Federal judge before whom a civil action with respect to prison
      conditions is pending who believes that a prison release order
      should be considered may sua sponte request the convening of a
      three-judge court to determine whether a prisoner release order
      should be entered.
        (E) The three-judge court shall enter a prisoner release order
      only if the court finds by clear and convincing evidence that - 
          (i) crowding is the primary cause of the violation of a
        Federal right; and
          (ii) no other relief will remedy the violation of the Federal
        right.

        (F) Any State or local official including a legislator or unit
      of government whose jurisdiction or function includes the
      appropriation of funds for the construction, operation, or
      maintenance of prison facilities, or the prosecution or custody
      of persons who may be released from, or not admitted to, a prison
      as a result of a prisoner release order shall have standing to
      oppose the imposition or continuation in effect of such relief
      and to seek termination of such relief, and shall have the right
      to intervene in any proceeding relating to such relief.

      (b) Termination of Relief. - 
        (1) Termination of prospective relief. - (A) In any civil
      action with respect to prison conditions in which prospective
      relief is ordered, such relief shall be terminable upon the
      motion of any party or intervener - 
          (i) 2 years after the date the court granted or approved the
        prospective relief;
          (ii) 1 year after the date the court has entered an order
        denying termination of prospective relief under this paragraph;
        or
          (iii) in the case of an order issued on or before the date of
        enactment of the Prison Litigation Reform Act, 2 years after
        such date of enactment.

        (B) Nothing in this section shall prevent the parties from
      agreeing to terminate or modify relief before the relief is
      terminated under subparagraph (A).
        (2) Immediate termination of prospective relief. - In any civil
      action with respect to prison conditions, a defendant or
      intervener shall be entitled to the immediate termination of any
      prospective relief if the relief was approved or granted in the
      absence of a finding by the court that the relief is narrowly
      drawn, extends no further than necessary to correct the violation
      of the Federal right, and is the least intrusive means necessary
      to correct the violation of the Federal right.
        (3) Limitation. - Prospective relief shall not terminate if the
      court makes written findings based on the record that prospective
      relief remains necessary to correct a current and ongoing
      violation of the Federal right, extends no further than necessary
      to correct the violation of the Federal right, and that the
      prospective relief is narrowly drawn and the least intrusive
      means to correct the violation.
        (4) Termination or modification of relief. - Nothing in this
      section shall prevent any party or intervener from seeking
      modification or termination before the relief is terminable under
      paragraph (1) or (2), to the extent that modification or
      termination would otherwise be legally permissible.

      (c) Settlements. - 
        (1) Consent decrees. - In any civil action with respect to
      prison conditions, the court shall not enter or approve a consent
      decree unless it complies with the limitations on relief set
      forth in subsection (a).
        (2) Private settlement agreements. - (A) Nothing in this
      section shall preclude parties from entering into a private
      settlement agreement that does not comply with the limitations on
      relief set forth in subsection (a), if the terms of that
      agreement are not subject to court enforcement other than the
      reinstatement of the civil proceeding that the agreement settled.
        (B) Nothing in this section shall preclude any party claiming
      that a private settlement agreement has been breached from
      seeking in State court any remedy available under State law.

      (d) State Law Remedies. - The limitations on remedies in this
    section shall not apply to relief entered by a State court based
    solely upon claims arising under State law.
      (e) Procedure for Motions Affecting Prospective Relief. - 
        (1) Generally. - The court shall promptly rule on any motion to
      modify or terminate prospective relief in a civil action with
      respect to prison conditions. Mandamus shall lie to remedy any
      failure to issue a prompt ruling on such a motion.
        (2) Automatic stay. - Any motion to modify or terminate
      prospective relief made under subsection (b) shall operate as a
      stay during the period - 
          (A)(i) beginning on the 30th day after such motion is filed,
        in the case of a motion made under paragraph (1) or (2) of
        subsection (b); or
          (ii) beginning on the 180th day after such motion is filed,
        in the case of a motion made under any other law; and
          (B) ending on the date the court enters a final order ruling
        on the motion.

        (3) Postponement of automatic stay. - The court may postpone
      the effective date of an automatic stay specified in subsection
      (e)(2)(A) for not more than 60 days for good cause. No
      postponement shall be permissible because of general congestion
      of the court's calendar.
        (4) Order blocking the automatic stay. - Any order staying,
      suspending, delaying, or barring the operation of the automatic
      stay described in paragraph (2) (other than an order to postpone
      the effective date of the automatic stay under paragraph (3))
      shall be treated as an order refusing to dissolve or modify an
      injunction and shall be appealable pursuant to section 1292(a)(1)
      of title 28, United States Code, regardless of how the order is
      styled or whether the order is termed a preliminary or a final
      ruling.

      (f) Special Masters. - 
        (1) In general. - (A) In any civil action in a Federal court
      with respect to prison conditions, the court may appoint a
      special master who shall be disinterested and objective and who
      will give due regard to the public safety, to conduct hearings on
      the record and prepare proposed findings of fact.
        (B) The court shall appoint a special master under this
      subsection during the remedial phase of the action only upon a
      finding that the remedial phase will be sufficiently complex to
      warrant the appointment.
        (2) Appointment. - (A) If the court determines that the
      appointment of a special master is necessary, the court shall
      request that the defendant institution and the plaintiff each
      submit a list of not more than 5 persons to serve as a special
      master.
        (B) Each party shall have the opportunity to remove up to 3
      persons from the opposing party's list.
        (C) The court shall select the master from the persons
      remaining on the list after the operation of subparagraph (B).
        (3) Interlocutory appeal. - Any party shall have the right to
      an interlocutory appeal of the judge's selection of the special
      master under this subsection, on the ground of partiality.
        (4) Compensation. - The compensation to be allowed to a special
      master under this section shall be based on an hourly rate not
      greater than the hourly rate established under section 3006A for
      payment of court-appointed counsel, plus costs reasonably
      incurred by the special master. Such compensation and costs shall
      be paid with funds appropriated to the Judiciary.
        (5) Regular review of appointment. - In any civil action with
      respect to prison conditions in which a special master is
      appointed under this subsection, the court shall review the
      appointment of the special master every 6 months to determine
      whether the services of the special master continue to be
      required under paragraph (1). In no event shall the appointment
      of a special master extend beyond the termination of the relief.
        (6) Limitations on powers and duties. - A special master
      appointed under this subsection - 
          (A) may be authorized by a court to conduct hearings and
        prepare proposed findings of fact, which shall be made on the
        record;
          (B) shall not make any findings or communications ex parte;
          (C) may be authorized by a court to assist in the development
        of remedial plans; and
          (D) may be removed at any time, but shall be relieved of the
        appointment upon the termination of relief.
