Checked against the BOP policy set · 2026-09-06.

A control unit is the Bureau of Prisons’ most restrictive housing assignment: a separate unit for people the Bureau has decided “are unable to function in a less restrictive environment without being a threat to others or to the orderly operation of the institution” (28 C.F.R. § 541.40(a); PS 5212.07 at p. 1). Unlike almost everything else in BOP restrictive housing, a control unit placement runs through a formal, adversarial-style hearing before an outside Hearing Administrator, with advance written notice, a staff representative, witnesses, a written decision, and a national-level appeal — because a federal court ordered it in 1980 and the Bureau then wrote it into the Code of Federal Regulations.

Three things that are frequently confused, stated once, plainly. A control unit is the unit governed by this page and by 28 C.F.R. §§ 541.40–541.50. The general population of USP Florence ADMAX — the federal supermax in Florence, Colorado — is restrictive housing but is not a control unit, and reaching it requires no control-unit hearing; see USP Florence ADMAX. A Special Housing Unit (SHU) is the short-term administrative-detention and disciplinary-segregation unit that nearly every federal prison has, governed by an entirely different subpart of the regulation; see Special Housing Units (PS 5270.12) and, for the plain-language version, Solitary Confinement and Special Housing Units. A person can be in the SHU without ever being near a control unit, and can be at ADX without being in one.

The rule itself: control units

PS 5212.07 does something no other Program Statement in this batch does: it tells you, on its own first page, which sentences are law and which are not. The footer of page 1 reads:

[Bracketed Bold – Rules] Regular Type – Implementing Information

Every passage in square brackets below is regulatory text — it appears, word for word, in 28 C.F.R. part 541, subpart D, which is still in force today. Everything in regular type is the Bureau’s internal instruction to its own staff. That distinction decides what a reader can enforce and what a reader can only ask for. Each quotation below was transcribed from bop.gov/policy/progstat/5212_007.pdf and independently confirmed against the current regulation on eCFR.

Who may be referred, and who may not

The Warden starts the process. PS 5212.07 at pp. 4–5, quoting 28 C.F.R. § 541.41(b):

[b. The Warden shall consider the following factors in a recommendation for control unit placement:

(1) Any incident during confinement in which the inmate has caused injury to other persons;

(2) Any incident in which the inmate has expressed threats to the life or well-being of other persons;

(3) Any incident involving possession by the inmate of deadly weapons or dangerous drugs;

(4) Any incident in which the inmate is involved in a disruption of the orderly operation of a prison, jail, or other correctional institution;]

[(5) An escape from a correctional institution.

(6) An escape attempt. Depending on the circumstances, an escape attempt, considered alone or together with an inmate’s prior history, may warrant consideration for a control unit placement.]

[(7) The nature of the offense for which committed. An inmate may not be considered solely on the nature of the crime which resulted in that inmate’s incarceration; however, the nature of the crime may be considered in combination with other factor(s) as described in paragraph (b) of this section.

Two limits sit inside that list and are easy to miss. Nothing beyond items (1) through (4) supports a referral without a written explanation: “Special reasons are required in the Warden’s request to the Regional Director to support the conclusion that the safety of the institution is threatened in a way other than those listed in (1) through (4) above” (p. 5). And the offense of conviction alone can never do the work — item (7) says so in the regulation itself.

The escape gloss at p. 5 is the Bureau’s own, and it is narrower than people assume:

An escape attempt involving the taking of hostages, or an escape attempt involving the use of weapons, warrants referral to the control unit. Other examples that may warrant a referral include: multiple escape attempts, an escape attempt otherwise involving injury or threat to life, or use of a deadly weapon.

Incidents involving the possession of escape tools or plans, an escape attempt not involving injury or threat to life or use of a deadly weapon ordinarily do not warrant a referral; designating a U.S. Penitentiary for the inmate should be considered first.

Then the two prohibitions, PS 5212.07 at p. 6, quoting § 541.41(c):

[c. The Warden may not refer an inmate for placement in a control unit:

(1) If the inmate shows evidence of significant mental disorder or major physical disabilities as documented in a mental health evaluation or a physical examination;]

[(2) On the basis that the inmate is a protection case, e.g., a homosexual, an informant, etc., unless the inmate meets other criteria as described in paragraph (b) of this section.]

Those two lines are the most useful sentences in the document for anyone opposing a referral, because they are regulation rather than policy — a genuine “may not,” not a staff instruction. The implementing text at p. 6 adds that “[a] mental health evaluation (by an appropriate mental health professional) and a medical (including dental) examination report (by medical staff) will be available for the Warden’s consideration prior to referring an inmate for a control unit placement,” and that if the person refuses to cooperate, “the psychologist will document this refusal in a report consisting of a record review and staff observation.”

The referral package itself is listed at pp. 3–4: a referral memorandum stating the basis, copies of all DHO reports, misconduct reports and investigative materials tied to the specific acts, an up-to-date progress report, a copy of the presentence investigation, an up-to-date mental health report, an up-to-date medical and dental report, and “[a] memorandum signed by the Health Services Administrator indicating whether there are any medical/dental problems that preclude placement in a control unit.”

The hearing

This is the part of the policy that has no counterpart anywhere else in BOP restrictive housing. The Regional Director where the person is held reviews the Warden’s recommendation; if he concurs, he forwards it to the Regional Director of the region where the control unit sits, who “shall designate a person in the Regional Office to review the referral material and to conduct a hearing” (§ 541.42(a); PS 5212.07 at p. 6). The Hearing Administrator must have correctional experience, must “[l]ack … former personal involvement in an Institution Discipline Committee action involving the particular inmate in incident(s) referred,” and must know BOP placement criteria (§ 541.42(b); p. 7).

The hearing rights, PS 5212.07 at pp. 7–9, quoting 28 C.F.R. § 541.43:

Right	The regulation’s own words	Pin-cite
Where the hearing happens	“The hearing ordinarily shall take place at the recommending or sending institution.”	PS 5212.07 at p. 7
Advance notice	“Staff shall provide an inmate with an advance written notice of the hearing and a copy of this rule at least 24 hours prior to the hearing. The notice will advise the inmate of the specific act(s) or other evidence which forms the basis for a recommendation that the inmate be transferred to a control unit, unless such evidence would likely endanger staff or others.”	PS 5212.07 at p. 7
If the person cannot read	“If an inmate is illiterate, staff shall explain the notice and this rule to the inmate and document that this explanation has occurred.”	PS 5212.07 at p. 7
Staff representative	“The Hearing Administrator shall provide an inmate the service of a full-time staff member to represent the inmate, if the inmate so desires. … The inmate may select a staff representative from the local institution. … When an inmate is illiterate, the Warden shall provide a staff representative.”	PS 5212.07 at p. 8
What the representative does	“The staff representative shall be available to assist the inmate and, if the inmate desires, shall contact witnesses and present favorable evidence at the hearing. The Hearing Administrator shall afford the staff representative adequate time to speak with the inmate and to interview available witnesses.”	PS 5212.07 at p. 8
Presence	“The inmate has the right to be present throughout the hearing, except where institutional security or good order is jeopardized. The Hearing Administrator may conduct a hearing in the absence of the inmate when the inmate refuses to appear.”	PS 5212.07 at p. 8
Witnesses and documents	“The inmate is entitled to present documentary evidence and to have witnesses appear, provided that calling witnesses would not jeopardize or threaten institutional security or individual safety, and further provided that the witnesses are available at the institution where the hearing is being conducted.”	PS 5212.07 at p. 8
The relevance limit	“The evidence to be presented must be material and relevant to the issue as to whether the inmate can and would function in a general prison population without being or posing a threat to staff or others or to the orderly operation of the institution. The Hearing Administrator may not consider an attempt to reverse or repeal a prior finding of a disciplinary violation.”	PS 5212.07 at p. 8
Absent witnesses	“When a witness is not available within the institution, or not permitted to appear, the inmate may submit a written statement by that witness. The Hearing Administrator shall, upon the inmate’s request, postpone any decision following the hearing for a reasonable time to permit the obtaining and forwarding of written statements.”	PS 5212.07 at p. 9
Refusals on the record	“The Hearing Administrator shall document in the record of the hearing the reasons for declining to permit a witness or to receive documentary evidence.”	PS 5212.07 at p. 9

Two implementing sentences make the difference in practice. If the Hearing Administrator “intends to consider any disciplinary actions the inmate received before or after the control unit referral, these actions must be referred to in the notice” (p. 7). And, at p. 9: “A staff witness whom the Hearing Administrator determines can present material and relevant evidence or testimony may not decline to appear.”

Attachment A, the Notice of Control Unit Hearing, is where all of this becomes a form the reader can actually hold. It carries checkboxes for staff representation, blanks for named witnesses and their expected testimony, and, at pp. 26–27, a printed list headed “Inmate Rights at Control Unit Hearing.” One line on that form matters more than any other: “Failure to complete the form will be considered as your waiver to witnesses and staff representation” (p. 25).

The decision, the Executive Panel, and the two appeals

Step	What the rule says	Pin-cite
Written decision	“[T]he Hearing Administrator shall prepare a written decision as to whether this placement is warranted,” including “a summary of the hearing and of all information presented upon which the decision is based” and “the specific reasons for the decision, to include a description of the act, or series of acts, or evidence on which the decision is based.”	PS 5212.07 at p. 9 (§ 541.44(a))
Notice to the person	The Hearing Administrator “shall advise the inmate in writing of the decision,” and shall advise that it goes to the Executive Panel and that the person may appeal. Information may be withheld only where “release of this information could pose a threat to individual safety, or institutional security.”	PS 5212.07 at pp. 9–10
First appeal — the deadline that catches people	“This appeal, with supporting documentation and reasons, must be filed within five working days of the inmate’s receipt of the Hearing Administrator’s decision.”	PS 5212.07 at p. 10
Transmission	“The Hearing Administrator shall send the decision, whether for or against placement in a control unit, and supporting documentation to the Executive Panel. Ordinarily this is done within 20 working days after conclusion of the hearing.”	PS 5212.07 at p. 10
Who the Executive Panel is	“The Executive Panel is composed of the Regional Director of the region where a control unit is located to which referral is being considered and the Assistant Director, Correctional Programs Division.”	PS 5212.07 at p. 10 (§ 541.45)
Panel deadline	“The Panel shall accept or reject the Hearing Administrator’s decision within 30 working days of its receipt, unless for good cause there is reason for delay, which shall be documented in the record.”	PS 5212.07 at p. 10
Second appeal	“An inmate may appeal a decision of the Executive Panel, through the Administrative Remedy Procedure, directly to the Office of General Counsel, Bureau of Prisons within 30 calendar days of the inmate’s receipt of the Executive Panel’s decision.”	PS 5212.07 at p. 11

Note what the second appeal skips. It goes straight to the Office of General Counsel — not warden, then region, then Central Office. That is a real departure from the ordinary Administrative Remedy Program ladder, and filing a BP-9 at the institution instead can burn the 30 days.

Two implementing points at p. 11 are worth marking. Approval does not mean immediate transfer: “the receiving institution Warden will place the inmate on a waiting list and must notify the referring Warden when housing is available. Pending transfer, the inmate is to be considered in holdover status.” And the referring Warden “will arrange for the inmate to receive a physical examination (ordinarily within 30 days of transfer to a control unit) and a current mental health evaluation (ordinarily within 90 days of transfer).”

What a control unit must provide

These are the numbers people write in for. All of them are regulatory text under 28 C.F.R. § 541.46 except where marked.

Service	The floor, in the rule’s own words	Pin-cite
Recreation	“Each inmate shall have the opportunity to receive a minimum of seven hours weekly recreation and exercise out of the cell.”	PS 5212.07 at p. 12
Group recreation	“Inmates ordinarily recreate individually.” To allow group recreation the Warden must route a recommendation through the Regional Director to the Assistant Director, Correctional Programs Division; “Only the Assistant Director may approve group recreation.” (implementing text)	PS 5212.07 at pp. 12–13
Visiting	“Staff shall allot a minimum of four hours per month visiting time to a control unit inmate. … All visitors must be on the inmate’s approved visiting list.” Visits are “conducted in a controlled visiting area, separated from regular visiting facilities.”	PS 5212.07 at p. 14
Medical	“A member of the medical staff shall visit control unit inmates daily. A physician will visit the unit as the need arises.”	PS 5212.07 at p. 13
Mental health	“During the first 30-day period in a control unit, staff shall schedule the control unit inmate for a psychological evaluation conducted by a psychologist. Additional individual evaluations shall occur every 30 days. … Inmates requiring prescribed psychotropic medication are not ordinarily housed in a control unit.”	PS 5212.07 at p. 14
Religion	“The institutional chaplains shall make at least weekly visits to the control unit. While individual prayer and/or worship is allowed in a control unit, religious assemblies or group meetings are not allowed.”	PS 5212.07 at p. 14
Education	“The Warden shall assign a member of the education staff to the control unit on at least a part-time basis to assist in developing an educational program to fulfill each inmate’s academic needs.”	PS 5212.07 at p. 11
Law library	“An inmate assigned to a control unit may use that unit’s inmate basic law library, upon request and in rotation.” The Bureau’s own gloss: “The governing concept is that an inmate must have access to the same legal reference books available to all other inmates.” (implementing text)	PS 5212.07 at p. 12
Legal storage	“Storage of legal materials is limited to three cubic feet.” (implementing text)	PS 5212.07 at p. 15
Commissary	“The amount of money which control unit inmates spend per month is comparable to the spending limitation for inmates residing in the general population. Staff may limit commissary items to ensure the safety and security of the unit.”	PS 5212.07 at p. 15
Personal property	“Personal property items shall be limited in number and type to ensure the safety and good order of the unit.” On admission, notice of “the type of personal property which is allowed in the unit (items made of glass or metal will not be permitted).”	PS 5212.07 at pp. 15–16
Correspondence	“Inmates confined in a control unit are provided correspondence privileges in accordance with the Bureau of Prisons’ rule on Inmate Correspondence (see 28 CFR, part 540).”	PS 5212.07 at p. 14

The umbrella sentence is the one to quote first: “The Warden shall provide the following services to a control unit inmate. These services must be provided unless compelling security or safety reasons dictate otherwise. These reasons will be documented and signed by the Warden, indicating the Warden’s review and approval” (§ 541.46; PS 5212.07 at p. 11). A denial that is not documented and signed by the Warden is a departure from the regulation, not merely from policy.

“Unit status” — the projected duration, and how time is credited

Everyone in a control unit is told a number on arrival. PS 5212.07 at p. 16, under § 541.47(a) (“Staff shall provide an inmate admitted to a control unit with … Notice of the projected duration of the inmate’s confinement in a control unit”):

(1) Staff must notify an inmate upon admission to a control unit of his or her “unit status” (projected duration of confinement in the control unit). In determining this, staff must give primary consideration to the nature of the act(s) that resulted in the control unit placement. Another factor to consider is the inmate’s behavior while in administrative detention pending actual placement.

(2) An inmate’s unit status, once established by the unit team, is to be reduced on a day-for-day basis for the time the inmate was in administrative detention prior to actual placement in a control unit. This “credit” includes both:

– time spent in administrative detention following the DHO hearing, but prior to the decision approving placement and – time spent in administrative detention following the placement decision, but prior to actual placement.

When more than one incident report is used as a basis for referral, or when a disciplinary sanction is not involved, the “credited” time is determined by the last incident on which the Warden made the referral. Time in disciplinary segregation is not credited.

(3) An inmate’s unit status may range from one month to any definite number of months. The unit team may increase or decrease unit status, once assigned, provided this is documented and dependent on behavior while assigned to the unit.

Read that carefully, because it is the most misunderstood paragraph in the document. “Unit status” is a projection the unit team sets and can change, not a sentence and not a release date. It can be increased as well as decreased. Nothing here — and nothing on this page — tells any particular person how long a placement will last, and nobody should treat a stated unit status as a promise. What the paragraph does give a reader is a concrete, checkable arithmetic claim: administrative-detention time before actual placement is supposed to come off the projection day for day, and disciplinary-segregation time is not. If the arithmetic on a program review does not reflect that, it is a specific, documentable error rather than a general complaint.

The rest of the admission notice, under § 541.47, covers the personal-property rule, “[a] summary of the guidelines and disciplinary procedures applicable in the unit,” “[a]n explanation of the activities in a control unit,” “[t]he expectations of the inmate’s involvement in control unit activities,” and “[t]he criteria for release from the unit, and how those criteria specifically relate to this confinement period in the unit and any specific requirements in the inmate’s individual case” (pp. 16–17).

The review cycle, and who can end a placement

Review	The rule	Pin-cite
Daily	“Unit staff shall evaluate informally and daily an inmate’s adjustment within the control unit.”	PS 5212.07 at p. 20 (§ 541.49(a))
Every 30 days	“Once every 30 days, the control unit team, comprised of the control unit manager and other members designated by the Warden (ordinarily to include the officer-in-charge or lieutenant, case manager, and education staff member assigned to the unit), shall meet with an inmate in the control unit. The inmate is required to attend the team meeting in order to be eligible for the previous month’s stay in the control unit to be credited towards the projected duration of confinement in that unit.”	PS 5212.07 at p. 20
What the team must have	“The unit team, at its 30-day review, must have available the collected daily activity data and mental health assessment reports; they will conduct a personal interview.” (implementing text, added by this 2001 edition)	PS 5212.07 at p. 20
Institutional review authority	“The Warden shall serve as the review authority at the institutional level for unit team actions.”	PS 5212.07 at p. 20
Appeal of a 30-day review	“An inmate may appeal the Warden’s decision to the Executive Panel within five working days of receipt of that decision. The inmate will receive a response to this appeal at the inmate’s next appearance before the Executive Panel.”	PS 5212.07 at p. 20
Executive Panel review	“At least once every 60 to 90 days, the Executive Panel shall review the status of an inmate in a control unit to determine the inmate’s readiness for release from the Unit. … Ordinarily, the inmate is interviewed in person at this review. If the inmate refuses to appear for this review, or if there is other reason for not having an in-person review, this will be documented.”	PS 5212.07 at pp. 20–21
Waiver of the in-person review	“The Executive Panel may waive an in-person review when available information indicates either minor or no change in the inmate’s status.” (implementing text)	PS 5212.07 at p. 21
Appeal of a Panel review	“An inmate may appeal a decision of the Executive Panel, through the Administrative Remedy Procedure, directly to the Office of General Counsel, Bureau of Prisons within 30 calendar days from the date of the Executive Panel’s response.”	PS 5212.07 at p. 21

The attendance sentence is the sleeper. Skipping the 30-day team meeting can mean the month does not count toward the projection — an easy thing to lose without realizing it.

Release is governed by § 541.50, PS 5212.07 at pp. 21–22:

[a. Only the Executive Panel may release an inmate from a control unit. The following factors are considered in the evaluation of an inmate’s readiness for release from a control unit:

(1) Relationship with other inmates and staff members, which demonstrates that the inmate is able to function in a less restrictive environment without posing a threat to others or to the orderly operation of the institution;

(2) Involvement in work and recreational activities and assignments;

(3) Adherence to institution guidelines and Bureau of Prisons rules and policy;

(4) Personal grooming and cleanliness; and

(5) Quarters sanitation.

b. An inmate released from a control unit may be returned:

(1) To the institution from which the inmate was originally transferred;

(2) To another federal or non-federal institution; or

(3) Into the general population of the institution which has a control unit.]

No warden, unit team, or regional office can release someone from a control unit. Only the two-member Executive Panel can. That single line explains why so much control-unit advocacy that is aimed at the institution goes nowhere.

Applied Insight — Christopher Zoukis, JD, MBA, Managing Director: The five-working-day appeal at PS 5212.07 at p. 10 is the shortest deadline anywhere in BOP restrictive housing, and it starts running on receipt of the Hearing Administrator’s written decision — which is why the policy directs staff to record the date and time of delivery on the notification and on the central-file copy. If a family member learns of a control unit hearing at all, the single most useful thing to do is call counsel that day, not that week. Two other documents are worth requesting immediately and are far easier to get in month one than in year two: the completed Attachment A notice, which shows on its face whether witnesses and a staff representative were requested or waived, and the Health Services Administrator’s memorandum required by PS 5212.07 at p. 4, which states whether any medical or dental problem precludes placement. Those two pages carry more weight in a later filing than any narrative.

What binds, what merely instructs, and why this document is unusual

A Program Statement is the Bureau’s internal instruction to its own staff. It is not a regulation, and a departure from it is not, by itself, a claim. The Supreme Court described a BOP Program Statement in Reno v. Koray, 515 U.S. 50 (1995), as an “internal agency guideline” akin to an interpretive rule that does not require notice and comment, though still entitled to some deference where it is a permissible construction of the statute. That is why this page says the policy “directs staff” to do something: it is precise language, not hedging.

PS 5212.07 is the rare Program Statement where the line is drawn on the page itself. The bracketed bold passages are the text of 28 C.F.R. §§ 541.40–541.50, promulgated through notice and comment and still in force. The regular-type passages are staff instruction. So:

• Regulation, and therefore binding on the Bureau: the 24-hour advance notice, the copy of the rule, the staff representative, the illiteracy protections, the right to be present, the right to call available witnesses and submit written statements from absent ones, the written decision with specific reasons, the five-working-day and 30-calendar-day appeals, the seven hours of weekly out-of-cell recreation, the four hours of monthly visiting, daily medical rounds, 30-day psychological evaluations, weekly chaplain visits, the two referral prohibitions, and the rule that only the Executive Panel may release.
• Policy, and therefore an instruction the Bureau gave itself: the escape-referral gloss, the three-cubic-foot legal-storage limit, the day-for-day credit arithmetic for unit status, the requirement that the 30-day team have daily activity data and mental health reports in hand, the waiting-list and holdover treatment pending transfer, and the Executive Panel’s ability to waive an in-person review.

That division is not academic. It decides whether a written complaint says “the Bureau violated 28 C.F.R. § 541.43(b)(2) by refusing a staff representative” or “the Bureau departed from its own Program Statement.” Both belong in an administrative remedy; only the first survives contact with a court on its own.

There is a further limit worth stating plainly. Congress has made the placement decision itself unusually hard to attack. 18 U.S.C. § 3621(b) gives the Bureau authority to “designate the place of the prisoner’s imprisonment” and to “at any time … direct the transfer of a prisoner from one penal or correctional facility to another,” and closes with: “Notwithstanding any other provision of law, a designation of a place of imprisonment under this subsection is not reviewable by any court.” The Third Circuit has separately noted that “BOP decisions about where to house inmates … are exempt from challenge under the APA,” citing 18 U.S.C. § 3625 — Murray v. Bledsoe, 650 F.3d 246, 247 n.1 (3d Cir. 2011) (per curiam). What survives is the constitutional and procedural claim, not the placement judgment.

What the courts have said

Three lines of authority set the frame, and the honest summary is that they run against the person challenging a placement more often than for.

Wolff v. McDonnell, 418 U.S. 539 (1974), is the source of the procedural template. It held that a prisoner facing discipline that may cost good-time credits must receive “written notice of the charges … no less than 24 hours” before the hearing, “a written statement by the factfinders as to the evidence relied on and reasons” for the action, and the chance “to call witnesses and present documentary evidence in his defense when permitting him to do so will not be unduly hazardous to institutional safety or correctional goals.” It expressly declined to require confrontation, cross-examination, or counsel. Anyone reading § 541.43 will recognize Wolff in it, item for item. But Wolff is a disciplinary case; the Court did not address non-disciplinary housing or classification decisions.

Bono v. Saxbe, 620 F.2d 609 (7th Cir. 1980), is where the control-unit hearing came from. Reviewing the control unit at USP Marion, the Seventh Circuit affirmed a district court order requiring “hearings, complete with the procedural safeguards …, to determine if each inmate in the Control Unit was there for the purported administrative purpose,” together with “periodic review of the reasons for their continued confinement.” The Bureau responded by codifying the procedure. Caution: Bono‘s liberty-interest reasoning rested on the mandatory-language approach that Sandin v. Conner later abandoned, and it carries negative treatment on that point. Cite it for the origin of the procedure and for its Eighth Amendment analysis, not for the proposition that a control unit placement automatically triggers due process today.

Sandin v. Conner, 515 U.S. 472 (1995), replaced that approach. State-created liberty interests “will be generally limited to freedom from restraint which … nonetheless imposes atypical and significant hardship on the inmate in relation to the ordinary incidents of prison life,” and thirty days of segregated confinement did not clear that bar. Wilkinson v. Austin, 545 U.S. 209 (2005), then applied the test to a state supermax and found a liberty interest where the conditions — near-total isolation, indefinite duration reviewed only annually, and disqualification from parole — combined; but it approved “informal, nonadversary procedures,” holding that “notice of the factual basis leading to consideration for OSP placement and a fair opportunity for rebuttal” plus “a short statement of reasons” satisfied due process. The procedures in § 541.43 are considerably more than Wilkinson requires.

In the federal system the leading decision is Rezaq v. Nalley, 677 F.3d 1001 (10th Cir. 2012), which held that the plaintiffs had no liberty interest in avoiding ADX confinement. The Tenth Circuit weighed whether the segregation furthers a legitimate penological interest, whether the conditions are extreme, whether the placement increases the duration of confinement, and whether it is indeterminate, and concluded that “the conditions in the general population unit at ADX are not extreme as a matter of law.” Two limits on that holding matter here. It concerned the general population unit at ADX, not a control unit — the court said so expressly. And the availability of periodic review cut against a liberty interest: “The availability of periodic reviews merely suggests that the confinement was not indefinite.” The control unit’s own 30-day and 60-to-90-day cycle is, in that framework, part of what makes the placement harder to attack.

Control-unit placements have reached the Tenth Circuit. In Jordan v. Wiley, 477 F. App’x 525 (10th Cir. 2012) (unpublished), a federal prisoner who had received “a Control Unit Hearing. See 28 C.F.R. § 541.43” challenged both the underlying discipline and the placement; the court dismissed most of the appeal as moot after his transfer out of ADX and its Control Unit, and rejected the rest because he “fail[ed] to show that he faces any ongoing atypical and significant hardship.” That is the usual shape of these cases and the reason to litigate the record while the person is still in the unit rather than after a transfer.

What a control unit referral means for you

If you are the person inside: the 24 hours before the hearing

Everything turns on the 24 hours before the hearing and the five working days after the decision. When Attachment A arrives, read paragraph 2 — the summary of the acts behind the referral — and paragraph 6, the printed list of rights. Name a staff representative in writing, even if you expect little from one, and name your witnesses with a one-line description of what each can say; the form states that failing to complete it counts as a waiver of both (p. 25). Keep in mind the relevance limit at p. 8: the hearing is not a place to re-litigate an old incident report, and the Hearing Administrator “may not consider an attempt to reverse or repeal a prior finding of a disciplinary violation.” What is relevant is whether you can function in general population. That is the question to answer.

If a mental-health condition or a serious physical disability is part of your history, say so before the referral leaves the institution, and ask that the psychologist’s report and the Health Services Administrator’s memorandum be completed — the referral prohibition at § 541.41(c)(1) is regulation, and it operates on documented findings, not on assertions. See Treatment and Care of Inmates With Mental Illness.

Once you are in the unit: attend every 30-day team meeting, because the policy conditions the month’s credit on your attendance (p. 20). Keep your own dated log of recreation hours offered and taken, medical rounds, chaplain visits, and psychological evaluations. The regulation sets floors — seven hours weekly out-of-cell, four hours of visits monthly, daily medical rounds, evaluations every 30 days — and a written record of shortfalls is worth far more than a recollection. The Bureau keeps its own: PS 5212.07 at p. 15 directs that detailed unit records be maintained on meals, showers, recreation, medication, medical and mental health treatment, and education activities, and that unusual behavior “both positive and negative” be recorded and added to the Inmate Central File.

If you are the family member: learning about a hearing afterwards

You will probably learn about a control unit hearing after it has happened, and the appeal window will already be short. If you learn about it before, the useful thing is speed, not volume: get counsel on the phone the same day.

What you can do reliably is documentary. Visits are limited to a minimum of four hours a month in a controlled, separate visiting area, and everyone visiting must already be on the approved list — so get on the list now rather than later; see Visiting Regulations and Inmate Visitation. Correspondence and telephone follow the ordinary rules at 28 C.F.R. part 540; see Correspondence and Inmate Telephone Regulations. Commissary spending is supposed to be comparable to general population, which is a checkable fact — see Trust Fund and Commissary.

Keep a dated chronology of every call and letter: what was said about recreation, medical rounds, mental health contacts, the 30-day meetings and the Executive Panel reviews. Families are often the only party keeping a written record, and that record is what converts a vague grievance into a specific one. If mental health is deteriorating, say so in writing to the institution’s psychology services and keep the copy; the Treatment and Care of Inmates With Mental Illness policy and Mental Health Programs for Inmates explain the routes.

If you are counsel: control unit referrals

Preserve the paper before it disperses. The file you want is the referral package described at PS 5212.07 at pp. 3–4 — the referral memorandum, the DHO reports and investigative materials tied to the specific acts, the progress report, the mental health report with the elements the policy enumerates, the medical and dental report, and the HSA memorandum — plus Attachment A as delivered, Attachment B as issued, the Executive Panel’s written decision, and each 30-day and 60-to-90-day review. Routes: the unit team, the Inmate Central File, and a Freedom of Information Act or Privacy Act request where staff will not produce.

Frame the claim around the regulation, not the Program Statement. Sandin and Rezaq make the liberty-interest threshold the hard part, and Rezaq expressly confined its “not extreme as a matter of law” holding to the ADX general population unit — leaving the control unit, with its more restrictive conditions, distinguishable on a developed record. Build that record on conditions, duration and the adequacy of review, which are the Rezaq factors. Note also that § 3621(b) forecloses review of the designation as such and § 3625 bars APA review, so the viable theories are constitutional, and the vehicle question — Bivens action versus § 2241 — matters; Murray v. Bledsoe, 650 F.3d at 247 n.1, treats a filing that does not challenge “the very fact or duration” of imprisonment as most accurately a Bivens action. See The § 2241 petition and Federal habeas corpus attorney.

Exhaustion is not optional. Under the Prison Litigation Reform Act, 42 U.S.C. § 1997e(a), no action about prison conditions may be brought until available administrative remedies are exhausted — and here the route is idiosyncratic: appeals from the Hearing Administrator go to the Executive Panel in five working days, and appeals from the Panel go to the Office of General Counsel in 30 calendar days, not through the ordinary institution-region-Central Office sequence.

What changed from PS 5212.06 to 5212.07

PS 5212.07, dated 2/20/2001, rescinded PS 5212.06, Control Unit Programs (8/29/95) — PS 5212.07 at p. 3. Its own Summary of Changes at p. 2 lists six items, and they are worth reading as a set because they are almost all about mental health and medical practice:

• “References to psychiatrist and psychiatric evaluation or report was changed to psychologist or psychological throughout the program statement.”
• “Section 2, Summary of Changes, was added.”
• “Section 6.c.(1) clarifies the requirement for mental health, medical, and dental evaluations prior a control unit referral. It also requires that an inmate’s refusal to cooperate with a mental health evaluation be documented.”
• “Section 11.e.(2) was revised to enact the prohibition of the purchase of weight training equipment for inmates.”
• “Section 14.b. requires medical staff to review an inmate’s medical record prior to granting an inmate’s request for a X-ray in lieu of a digital search to detect contraband. The clause, ‘no more than two abdominal X-rays per year for non-medical purposes,’ was removed.”
• “Section 15.a. clarifies the requirements for the unit team during 30 day reviews. They must have the collected daily activity data and the mental health assessment report. In addition, a personal interview with the inmate is to be conducted.”

Nothing has changed since. The Program Statement has not been reissued in twenty-five years, and BOP’s mass reissue of 23 Program Statements effective 22 June 2026, along with the February–May 2026 reissues, did not touch it. The regulation is even older: the eCFR source notes date §§ 541.46, 541.49 and 541.50 to 49 FR 32991 (Aug. 17, 1984), as amended at 60 FR 46484–85 (Sept. 6, 1995). Subpart D is the one part of 28 C.F.R. part 541 that BOP’s 2011 rewrite of the discipline and SHU rules left alone.

The world around it moved anyway. Five of the directives PS 5212.07 references have been superseded: PS 1330.11, Administrative Remedy Procedure for Inmates (10/29/93), is now PS 1330.18; PS 5265.11, Correspondence (7/9/99), is now PS 5265.14; PS 5270.07, Inmate Discipline and Special Housing Units (12/29/87), split years ago into PS 5270.09, Inmate Discipline Program, and PS 5270.12, Special Housing Units (3/5/2024, CN-1 3/6/2025); PS 5521.05, Searches (6/30/97), is now PS 5521.06, Searches of Housing Units, Inmates, and Inmate Work Areas; and PS 6000.05, Health Services Manual (9/15/96), has been succeeded by the current patient-care and clinical directives. The current SHU statement still cross-references this one — PS 5270.12 at p. 21: “For additional information regarding Control Unit procedures, see the Program Statement Control Unit Programs.”

The other thing that changed is doctrinal. PS 5212.07 was drafted against Bono v. Saxbe and the mandatory-language liberty-interest cases. Sandin (1995) and Wilkinson (2005) reset that analysis, and Rezaq (2012) applied the new framework to ADX. The procedures in the regulation are unchanged and remain enforceable as regulation; what changed is how much constitutional weight a court will place on them.

Where people get stuck on the five-working-day appeal

The five-working-day appeal is gone before anyone notices. This is the single most common failure. The clock starts on receipt of the Hearing Administrator’s written decision — and the policy directs staff to record the date and time of delivery on the notification and the central-file copy (p. 10), which means the date is documented and is checkable. If the deadline has passed, do not simply file late without explanation: the general administrative-remedy rule at 28 C.F.R. § 542.14(a) allows an extension “[w]here the inmate demonstrates a valid reason for delay,” and a documented late delivery, a transfer in transit, or a period in which the person had no access to the form is the kind of reason to state and support. Start with an Inmate Request to Staff — form BP-A0148, universally called a “cop-out” — asking for the dated delivery record; see Request to Staff.

The appeal is filed at the wrong place. Control-unit appeals do not run warden → region → Central Office. The Hearing Administrator’s decision is appealed to the Executive Panel; the Panel’s decision is appealed “through the Administrative Remedy Procedure, directly to the Office of General Counsel” (pp. 10, 11, 21). Filing a BP-9 at the institution instead can consume the window and produce a rejection for filing at the wrong level. BOP publishes BP-A0148 but does not publish the BP-9, BP-10 or BP-11 forms; the unit team supplies those. See Administrative Remedy Program and Prison Grievances.

A service floor is missed and the complaint is written too generally. “I’m not getting rec” goes nowhere. “I received four hours of out-of-cell recreation in the week of [date], not the seven-hour minimum in 28 C.F.R. § 541.46(e)(1), and no written denial signed by the Warden was provided as § 541.46 requires” is a different document. The same structure works for the four hours of monthly visiting, daily medical rounds, 30-day psychological evaluations, weekly chaplain visits, and the commissary comparability rule. Cite the section number, give dates, and ask for the Warden’s signed documentation of any denial.

Unit-status arithmetic is wrong, and nobody checks it. Administrative-detention time before actual placement is supposed to reduce unit status day for day; disciplinary-segregation time is not credited; and a month in which the person did not attend the 30-day team meeting may not be credited at all (pp. 16, 20). Ask, in writing, for the unit team’s calculation — the starting projection, the administrative-detention credit applied, and each month credited or not — and compare it to your own dates. Where the underlying dispute is really about designation, sentence computation, or medical care rather than the unit itself, the administrative remedy is necessary but rarely sufficient; that belongs in a consult.

The paired page is USP Florence ADMAX, the administrative-maximum penitentiary in Florence, Colorado, and it is the page to read for what the facility is, where it is, and how to reach someone there. The neighboring institutions in the Florence complex have their own records: USP Florence, FCI Florence, and the full Colorado federal prisons list. USP Marion is where the control unit litigated in Bono v. Saxbe was housed.

The restrictive-housing neighbors, each of which is a different thing: Special Housing Units (PS 5270.12) for administrative detention and disciplinary segregation; Special Management Units (PS 5217.02) for the SMU program, which is non-punitive, level-based and has no C.F.R. subpart of its own; Communications Management Units (PS 5214.05) for the units that restrict contact with the outside world rather than movement inside; Reintegration Housing Units for the step-down model; and Protective Custody, which § 541.41(c)(2) says cannot by itself support a control unit referral.

The policies that feed a referral or govern life inside: Inmate Discipline Program (PS 5270.09), because DHO reports are the raw material of a referral; Security Designation and Custody Classification (PS 5100.08) for how the institution was chosen; Central Inmate Monitoring System (PS 5180.05) for separatee assignments; Searches of Housing Units, Inmates, and Inmate Work Areas (PS 5521.06) for the digital and X-ray search rules at §§ 541.48; Inmate Legal Activities (PS 1315.08) for law-library access; Religious Beliefs and Practices (PS 5360.10); Inmate Personal Property (PS 5580.10); and Correctional Services Procedures Manual (PS 5500.14) for the observation requirements that apply to continuously locked-down units.

Routes and records: Administrative Remedy Program (PS 1330.18), Request to Staff (PS 5511.08), Inmate Central File and Privacy Folder (PS 5800.17), FOIA and Privacy Act Requests, and the BOP Regional Offices and Central Office, which is where the Executive Panel members and the Office of General Counsel sit.
