Rule 46 CSC Monthly Reviews: No Requirement for Separate “Segregation” Decision Where DC Placement Necessarily Entails Removal from Association; Article 8 Proportionality Can Be Sustained by Risk-Assessment Non‑Engagement

1. Introduction

Thakrar, R (On the Application Of) v Secretary of State for Justice (Rev1) [2026] EWCA Civ 503 concerned the lawfulness of the continued segregation of Mr Kevan Thakrar, a life-sentence prisoner managed within the Close Supervision Centre (“CSC”) system in the Long Term High Security Estate.

The appellant challenged (by judicial review) decisions taken on behalf of the Secretary of State through the CSC regime to keep him removed from association, including lengthy periods held in Designated Cells (“DCs”) under Prison Rule 46. The case turned on (i) what Rule 46 monthly reviews must address, (ii) the adequacy of reasons and procedural fairness, and (iii) substantive ECHR proportionality—especially where the prisoner’s non-engagement with psychological assessment impedes risk assessment and progression.

The Court of Appeal (Bean LJ, Baker LJ, May LJ) dismissed the appeal, upholding the High Court’s rejection of the claim.

Key issues

  • Rule 46 reviews: whether the CSC Management Committee (“CSCMC”) had to conduct a distinct monthly decision on “segregation within CSC” separate from “placement in CSC”.
  • Reasons/procedural fairness: whether the appellant received “genuine and meaningful” reasons enabling representations.
  • Article 3: whether prolonged segregation reached the minimum severity threshold; and how “beyond reasonable doubt” operates in Article 3 adjudication.
  • Article 8: whether continued segregation was disproportionate, including in circumstances where the appellant would not engage in assessments except on his own “terms”.
  • Article 14: whether Rule 46 prisoners were discriminated against compared with Rule 45 segregated prisoners in procedural safeguards.

2. Summary of the Judgment

  1. Rule 46 monthly review scope accepted (Awale): the Court accepted that Rule 46 monthly reviews must consider both (i) placement within the CSC estate and (ii) any further removal from association within CSC.
  2. No separate “two-track” decision-making required: despite the dual focus, the Court held Rule 46 did not require separate decision processes; where the prisoner is held in a DC, review of that DC placement necessarily entails review of removal from association.
  3. Reasons were adequate in context: the Court held the appellant was given sufficient information through letters, monthly MDT reports, CMP processes, and feedback to understand what he needed to do to progress; the reasons were not unlawfully “secret and unchallengeable”.
  4. Article 3 not breached: even applying ordinary civil standards, the appellant’s conditions did not approach the “minimum level of severity” required; the regime was not properly characterised as full solitary confinement.
  5. Article 8 proportionality upheld: continued segregation was justified by safety/risk management needs where the appellant’s non-engagement prevented robust risk assessment; the prison service had offered multiple engagement modalities.
  6. Article 14 claim failed: even assuming comparability between Rule 45 and Rule 46 cohorts, Rule 46 safeguards were not inferior; Rule 46 requires monthly renewals by/for the Secretary of State.
  7. Standard of proof clarification: “beyond reasonable doubt” in Strasbourg formulations relates to fact-finding, not the legal classification of treatment as Article 3 ill-treatment (relying on R(VC)).

3. Analysis

3.1 Precedents Cited

Procedural and evidential approach in judicial review

  • Singh v SSHD [2018] EWCA Civ 2861: cited below for the proposition that where evidence is uncontradicted and no cross-examination is sought, the court will generally proceed on that evidence unless it “cannot be correct”. Although the appeal focused elsewhere, this shaped the High Court’s approach to disputed factual narratives.
  • Floreat Investment Management Ltd v Churchill [2023] EWCA Civ 440: used to justify more careful appellate scrutiny given the High Court’s very lengthy delay in handing down judgment.

Rule 46 review content and structure

  • R (Awale) v Secretary of State for Justice [2024] EWHC 2322 (Admin): pivotal. The Court of Appeal treated Awale’s conclusion as accurate and accepted by the Secretary of State: monthly Rule 46 reviews must consider both CSC placement and (where applicable) removal from association within CSC. The present judgment develops Awale by holding that this dual consideration does not mandate separate formal decision “tracks” where the prisoner’s DC location inherently entails segregation.

Reasons and procedural fairness in segregation decisions

  • R (Bourgass) v SSJ [2015] UKSC 54; [2016] AC 384: central to the common law duty of disclosure of reasons. Lord Reed’s requirement of “genuine and meaningful disclosure” and warning against “secret and unchallengeable allegations” informed the Court’s assessment of whether the appellant had “the substance” needed to respond. Bourgass also underpinned the conceded procedural flaw (committee composition) relevant to Article 8 “in accordance with the law”.

Article 3: threshold, segregation, and standard of proof

  • Ocalan v Turkey (2005) 41 EHRR 45: referenced for the Strasbourg articulation of “beyond reasonable doubt” as an evidential standard derived from strong, concordant inferences—treated by the Court of Appeal as relating to facts.
  • R (Bary) v SSJ & The Governor of HMP Long Lartin [2010] EWHC 587 (Admin): noted as repeating the “beyond reasonable doubt” formulation, but the Court cautioned against decontextualised usage.
  • R(VC) v SSHD [2018] EWCA Civ 57; [2018] 1 WLR 4781: key corrective. “Beyond reasonable doubt” applies to determining what occurred; whether established facts meet Article 3 is a legal evaluative judgment not governed by a criminal standard.
  • Ireland v UK (1978) 2 EHRR 25: source of the “minimum level of severity” test; emphasises the contextual, circumstance-sensitive evaluation.
  • Ramirez Sanchez v France (2007) 45 EHRR 49: important comparator on long isolation without Article 3 violation; used to illustrate the high threshold and the limited utility of abstract statements about “indefinite” isolation.
  • Ahmad v UK (2013) 56 EHRR 1: used for the relevant factors in prison ill-treatment cases, and for the proposition that solitary confinement cannot be indefinite—yet the Court treated the step from prolonged segregation to Article 3 breach as “very major”.
  • Van der Ven v The Netherlands (2003) 38 EHRR 46 and Ilascu v Moldova (2004) 40 EHRR 46: cited for the repeated Strasbourg statement that removal from association is not in itself inhuman or degrading; assessment depends on conditions, stringency, duration, objective, and effects.
  • R (AB) v SSJ [2021] 3 WLR 494: treated as the leading domestic synthesis on Article 3 and removal from association, emphasising the multi-factor evaluative approach and the absence of rigid time limits.
  • Abu v Secretary of State for Justice [2025] EWHC 3526 (Admin): identified as a rare domestic instance where Article 3 succeeded in this context, but distinguished as turning critically on unaddressed mental health needs and suicide risk; the Court of Appeal noted an application for permission to appeal.
  • Kudla (as referenced in Abu): used indirectly to underline that distress exacerbated by mental health conditions is not automatically sufficient for Article 3; what mattered in Abu was the failure to obtain assessment/treatment in the face of acute risk.

Article 8 proportionality and penological judgment

  • Shahid v Scottish Ministers [2015] UKSC 58; [2016] AC 429: important comparator. Shahid succeeded under Article 8 (though not Article 3) where authorities failed for years to consider transfer or formulate a meaningful reintegration plan for a prisoner segregated for his own safety. The Court used Shahid to frame (and reject) the appellant’s argument that longer segregation demands more “creative” alternatives; here, the Court found repeated attempts at engagement and an existing pathway structured through CMPs.
  • Vavricka v Czech Republic (2021) 51 BHRC 241: relied on by the appellant to argue that imposing a detriment for non-compliance with a medical process engages Article 8. The Court accepted engagement but held it did not advance the core issue—proportionality—where the interference was justified.
  • R (Sneddon) v Secretary of State for Justice [2024] EWCA Civ 1258; [2025] KB 245: cited for deference/respect to expert decision-making in risk assessment of potentially violent prisoners.

3.2 Legal Reasoning

(A) Rule 46 monthly reviews: substance over form

The Court’s key doctrinal move was to reconcile (i) the accepted proposition from R (Awale) v Secretary of State for Justice [2024] EWHC 2322 (Admin) that Rule 46 monthly reviews must consider both CSC placement and intra-CSC segregation, with (ii) the operational reality that for a prisoner held in a DC, location and segregation are functionally inseparable.

The Court held that the CSCMC’s review of a prisoner’s continued DC placement necessarily constitutes review of continued removal from association; Rule 46 does not impose a requirement for a separate “segregation decision workflow” so long as the record shows the committee addressed what needed to be addressed.

(B) Reasons: the “Bourgass” standard applied to the CSC ecosystem

Applying R (Bourgass) v SSJ [2015] UKSC 54; [2016] AC 384, the Court examined whether the appellant received sufficient substance to respond. It treated the reasons question as contextual: not confined to short “feedback” boxes on forms, but including:

  • the initial detailed letter explaining the DC move;
  • monthly MDT reports disclosed to the prisoner for comment/representation;
  • the CMP structure and targets, and regular review processes;
  • meeting minutes and repeated articulation that progression depended on engagement enabling risk assessment.

The Court’s reasoning is that “formulaic” phrasing does not necessarily equate to inadequate reasons where the prisoner has been repeatedly told, with adequate specificity, what risk concerns exist and what conduct (engagement steps) is required to reduce them.

(C) Article 3: a clarification on “beyond reasonable doubt”

The Court addressed the High Court’s statement that the claimant must prove an Article 3 breach “beyond reasonable doubt”. Drawing on R(VC) v SSHD [2018] EWCA Civ 57; [2018] 1 WLR 4781, it clarified that Strasbourg’s “beyond reasonable doubt” is directed to fact-finding, not the legal evaluative question of whether the facts amount to inhuman or degrading treatment.

Nonetheless, the Court found the Article 3 claim failed even on ordinary civil standards: the regime involved significant contact (staff, visits, phone calls), and did not approach the severity threshold as analysed in R (AB) v SSJ [2021] 3 WLR 494, Ahmad v UK (2013) 56 EHRR 1, and Ramirez Sanchez v France (2007) 45 EHRR 49.

(D) Article 8: non-engagement as a proportionality-relevant fact

The Court accepted that the High Court should have analysed the substantive Article 8 proportionality issue notwithstanding the narrow concession. It therefore undertook that analysis itself.

The Court treated the decisive consideration as risk management necessity: for a prisoner assessed as a potential perpetrator of serious violence, the absence of an up-to-date risk assessment (because of refusal to engage except on self-imposed conditions) could rationally justify continued segregation. The Court emphasised evidence of repeated efforts to engage the appellant by offering different modalities (including discussions at his cell door and alternative supervised settings), and rejected the characterisation of segregation as a coercive “plan” to break his will.

The judgment therefore frames Article 8 proportionality in CSC cases as strongly influenced by (i) the offender’s risk profile, (ii) the availability and reasonableness of engagement routes offered by the state, and (iii) whether the prisoner’s own stance blocks necessary assessment integral to safe reintegration.

(E) Article 14: Rule 46 safeguards not inferior

The Court rejected the argument that Rule 46 segregated prisoners face inferior procedural safeguards compared with Rule 45 segregated prisoners. It reasoned that Rule 46 requires more frequent renewals (monthly), and that decisions rest with (or on behalf of) the Secretary of State rather than governors. Accordingly, even assuming sufficient comparability, no unjustified difference in treatment was made out.

3.3 Impact

  • Operational defensibility of CSCMC processes: the judgment supports the proposition that Rule 46 compliance is assessed by substantive engagement with required questions, not by insisting on artificial formal separation between “placement” and “segregation” decisions—particularly where DC placement inherently entails removal from association.
  • Reasons can be “distributed” across documents: it confirms that “reasons” may be communicated through an integrated regime of letters, CMPs, MDT reports, and minutes, provided the prisoner can understand and respond to the substance.
  • Article 3 threshold reaffirmed (and Abu distinguished): the Court underscores how difficult it is to establish Article 3 breach from segregation absent acute additional factors (notably serious unmet mental health needs), and cautions against overreliance on abstract statements about “indefinite” isolation.
  • Article 8 proportionality and prisoner non-engagement: the decision strengthens the position that where the state offers reasonable routes to risk assessment and progression, a prisoner’s refusal to engage can legitimately weigh heavily in favour of continued restrictive measures.
  • Rule 45 vs Rule 46 discrimination claims: by characterising Rule 46 as at least as protective procedurally (monthly renewals by/for the Secretary of State), the judgment may make future Article 14 challenges more difficult unless a claimant identifies a concrete deficiency in Rule 46 practice rather than its architecture.

4. Complex Concepts Simplified

Removal from association / segregation
Keeping a prisoner apart from other prisoners. Under Rule 46 this may happen within CSC (e.g., “single unlock”) or by placing the prisoner in a Designated Cell (DC), which prevents mixing even with other CSC prisoners.
Rule 45 vs Rule 46
Rule 45 is a governor-led segregation power with escalating time controls and eventual Secretary of State involvement. Rule 46 is Secretary of State-led and is designed for the CSC system managing the most dangerous/disruptive prisoners, with monthly renewal.
CMP (Care and Management Plan)
A structured plan setting out risks, needs, and targets for a CSC prisoner, reviewed periodically; it is the main framework for decisions about progression and placement.
“Genuine and meaningful disclosure” (Bourgass)
The prison must explain enough of the real reasons for segregation so the prisoner can make informed representations. It is not enough to provide vague, formulaic statements if the substance is effectively secret.
Article 3 “minimum level of severity”
Article 3 is only breached when treatment reaches a high threshold of seriousness, assessed in context (conditions, duration, purpose, effects). Removal from association is not automatically an Article 3 breach.
“Beyond reasonable doubt” in Article 3 cases
In Strasbourg usage it relates to how sure the court must be about disputed facts. Whether those facts amount to “inhuman or degrading treatment” is a legal judgment, not a criminal-standard fact question.
Article 8 proportionality
Even where private-life rights are interfered with (e.g., through segregation), the state may justify the interference if it pursues a legitimate aim (like safety) and is no more restrictive than necessary in the circumstances.

5. Conclusion

The Court of Appeal’s decision consolidates a practical approach to Rule 46 governance: monthly reviews must address both CSC placement and intra-CSC segregation, but the law does not require artificially separate decision structures where a prisoner’s DC placement inherently entails removal from association. It also reinforces that adequate reasons may be supplied through the CSC’s broader documentation ecosystem, provided the prisoner can understand the case to meet.

On the ECHR, the judgment reaffirms the high threshold for Article 3 breaches in segregation cases and clarifies that “beyond reasonable doubt” is principally a fact-finding concept. Under Article 8, it emphasises that where risk assessment is necessary for safe association, a prisoner’s sustained refusal to engage (save on self-imposed conditions) can make continued segregation a proportionate response. Finally, it weakens Article 14 challenges based on alleged inferiority of Rule 46 safeguards relative to Rule 45, holding Rule 46’s architecture to be at least as protective in review frequency and authorisation level.
