SAG, R (On the Application Of) v Governing Body of Winchmore School

England and Wales Court of Appeal (Civil Division)
Oct 21, 2025
Smart Summary (Beta)

Summary of Anonymised Opinion

Factual and Procedural Background

The Appellant, a 14‑year‑old pupil represented by a litigation friend (her mother), challenged by way of judicial review a decision of the Governors' Disciplinary Committee (the "GDC") of Company A to uphold, on reconsideration, an earlier decision of the Headteacher to permanently exclude the Appellant for misconduct.

Chronology (as recorded in the opinion):

  1. Headteacher's exclusion letter dated 5 February 2025 notified the Appellant of a permanent exclusion for an incident on a school trip (possession of a mobile phone with a SIM card and entering a teacher's room without permission to retrieve the phone).
  2. The GDC met on 3 March 2025 and issued a letter on 6 March 2025 upholding the Headteacher's decision.
  3. The Appellant applied for an independent review. An Independent Review Panel (IRP) quashed the GDC's decision by letter dated 31 March 2025 and directed that the GDC reconsider.
  4. The GDC reconvened on 8 April 2025 and issued a reconsideration letter dated 23 April 2025 maintaining the original decision. The judicial review challenge in these proceedings was limited to that reconsideration decision.

Procedural history in the courts (as recorded):

  • Permission for judicial review was granted by a Deputy High Court Judge (Judge Cameron) and the judge below dismissed the judicial review. The judgment at first instance is reported as [2025] EWHC 2117 (Admin).
  • The appeal was expedited to limit disruption to the Appellant's education. Anonymity was granted to the Appellant and her litigation friend.

Legal Issues Presented

  1. Was the GDC's reconsideration decision unreasonable or irrational in finding that the Appellant's conduct amounted to a sufficiently serious breach of the behaviour policy to justify permanent exclusion?
  2. Was the GDC's finding that allowing the Appellant to remain in school would "seriously harm" the education or welfare of the pupil or others (the "second limb") unreasonable or irrational?
  3. Did the GDC fail to adequately consider alternatives to permanent exclusion (i.e. was permanent exclusion applied without treating it as a last resort)?
  4. Procedural issue invoked by the School below (not appealed): whether judicial review was available in respect of the reconsideration decision or whether an IRP reference was the alternative remedy.

Arguments of the Parties

Appellant's Arguments (summarised)

  • The permanent exclusion was disproportionate in the circumstances of a single non‑violent incident on a school trip and therefore unreasonable.
  • The GDC and Headteacher had applied the School's (Company A's) written Behaviour Policy improperly, because the Behaviour Policy purported to require an "extremely serious" single incident for permanent exclusion whereas the conduct was at most "serious".
  • The reconsideration process failed to correct procedural flaws identified by the IRP (notably the ex parte discussion between the Headteacher and the governors) and did not properly consider alternatives to permanent exclusion.
  • The judge below failed to apply a sufficiently intense (heightened) standard of judicial review appropriate to permanent exclusion decisions and thus afforded too much deference to the school's evaluative judgments.

Respondent / School's Arguments (summarised)

  • The decision to apply a heightened intensity of review was wrong; the court should give deference to expert, local decision‑makers such as a headteacher and governors.
  • The GDC, on reconsideration, had properly applied the statutory guidance and had set out reasons relevant to the second limb; the judge below was right to conclude the decision was not irrational or unreasonable even after intense scrutiny.
  • Any reference in the reconsideration decision to an alleged criminal offence (burglary) was an incidental error that did not materially affect the outcome; section 31(2A) of the Senior Courts Act 1981 applied so that the error did not lead to different outcome on the balance of probabilities.
  • The governing body's two published policies should be read together; in substance there was no relevant conflict that would make the exclusion unlawful.

Table of Precedents Cited

Precedent Rule or Principle Cited For Application by the Court
R (oao TZA) v a Secondary School [2025] EWCA Civ 200 ("TZA") Recent authoritative examination of the statutory provisions governing permanent exclusion and governors' reconsideration role. The court treated TZA as the starting point for statutory construction and did not seek to revise its analysis; it informed the understanding of the governors' role as part of a single decision‑making process.
R v Governing Body of Dunraven School ex parte B [2000] LGR 494 Governors' discipline committee is part of a single decision‑making process, not simply a tribunal of appeal from the headteacher. Used to support the proposition that the GDC must make its own evaluative judgment and not merely review the headteacher's decision for legality.
R (RWU) v A Governing Body of A Academy [2024] EWHC 2828 ("RWU") Effect of quashing by an IRP: the governors must reconsider "afresh" lawfulness, reasonableness and procedural fairness; guidance on scope of reconsideration. Relied upon for the proposition that quashing requires an afresh reconsideration and that what matters is that the GDC "look afresh" at reinstatement in light of IRP findings.
R v SSHD, ex p Bugdaycay [1987] AC 514; R v SSHD, ex p Brind [1991] 1 AC 696 Origins and context of the phrase "anxious scrutiny" and the idea that heightened scrutiny may be appropriate where gravity of consequences demands it. Authorities invoked to justify that permanent exclusion (with its significant consequences) attracts a relatively exacting intensity of review.
R (Law Society) v Lord Chancellor [2018] EWHC 2094 ([2019] 1 WLR 1649) Rationality includes process rationality and outcome rationality; both the reasoning process and the outcome may be challenged as unreasonable. Quoted to explain the distinction between errors in reasoning (process irrationality) and outcomes that are outside the range of reasonable decisions (outcome irrationality).
R v Parliamentary Commissioner for Administration ex p Balchin [1998] 1 PLR 1 Illustration of decision that "does not add up" — used in explaining process irrationality. Appears in the analytical framework for identifying logical gaps or unexplained evidential leaps in decision‑making.
R (Wells) v Parole Board [2019] EWHC 2710 The court should ask whether the conclusion follows from the evidence or whether there is an unexplained evidential gap or leap. Cited to support the requirement that conclusions must be justified by evidence and reasoning without unexplained leaps.
Associated Provincial Picture Houses Ltd v Wednesbury Corporation [1948] 1 KB 223 Classic authority on Wednesbury unreasonableness/outcome irrationality. Used as the baseline concept for outcome irrationality: whether a decision is so unreasonable that no reasonable authority could have come to it.
Boddington v British Transport Police [1999] 2 AC 143 Used in conjunction with Wednesbury principle to describe the "range of reasonable decisions" concept. Supported the description of outcome review as assessment whether a decision is within the range of reasonable responses.
R v Department for Education and Employment ex p Begbie [2000] 1 WLR 1115 Wednesbury as a "sliding scale" — intensity of review varies with gravity of interests at stake. Referenced to explain that the standard of rationality review is flexible and should reflect the seriousness of the interests affected (e.g., permanent exclusion).
Kennedy v Charity Commission [2014] UKSC 20; Pham v Secretary of State for the Home Department [2015] UKSC 19 Discussion of proportionality, the extent to which courts can form their own view of balance struck by decision‑maker, and how heightened scrutiny may narrow the range of reasonable decisions. Quoted in relation to how close the court may review evaluative balancing and when the court may assess whether the range of reasonable decisions is narrow.
R (YH (Iraq)) v Secretary of State for the Home Department [2010] EWCA Civ 116 Commentary that "anxious scrutiny" is descriptive of a judicial attitude in contexts with serious human consequences and the need to ensure factors favouring an applicant are properly taken into account. Used to explain the meaning and application of "anxious scrutiny" (heightened scrutiny) in sensitive contexts.
R (KM) v Cambridgeshire County Council [2012] UKSC 23 Respect for evaluative judgments of decision‑makers where statutory discretion is vested in them. Invoked to support the proposition that courts should afford a degree of respect to evaluative judgments in areas where discretion is entrusted to other bodies.
R (Greenfields (IoW) Ltd) v Isle of Wight Council [2025] EWCA Civ 488 Guidance on applying s.31(2A) of the Senior Courts Act 1981 (the "highly likely" test): assess impact of error on decision to see whether outcome would have been substantially different. Applied by the judge below (and considered on appeal) in assessing whether the GDC's erroneous reference to burglary was material to the outcome.
R (SB) v Governors of Denbigh High School [2002] UKHL 15 Courts should be cautious about second‑guessing schools because they lack local knowledge and expertise. Referred to as a reminder of limits to court intervention in school disciplinary matters and the need for deference to school decision‑makers' expertise.
R (KP) v Secretary of State for Foreign, Commonwealth and Development Affairs [2025] EWHC 370 Analysis of rationality review; distinction between process rationality and outcome rationality and how intensity of review is calibrated. Cited and followed for detailed discussion of process/outcome rationality and the circumstances where heightened scrutiny is warranted.

Court's Reasoning and Analysis

The multi‑judge opinion contains three principal judgments with differing outcomes. The following summarises each judge's reasoning, focusing on legal principles the panel used to reach its view.

Judge Edis — Key reasoning (allowing the appeal)

  1. Framework and approach:
    • Applied the statutory framework (Education Act 2002 s51A, Education and Inspections Act 2006 ss88–89, and the 2012 Regulations) and the Secretary of State's Guidance; noted TZA as controlling authority.
    • Adopted the analytical distinction between process rationality (errors in reasoning/noise in decision‑making) and outcome rationality (decision outside the range of reasonable responses) as explained in KP and related authorities.
    • Accepted that permanent exclusion cases attract a heightened intensity of review (a "relatively exacting standard") because of the gravity of consequences for the pupil.
  2. Application to facts — three principal defects identified:
    • Failure to apply the Behaviour Policy's threshold: The Behaviour Policy (as distinct from the Exclusion & Suspension Policy) required an "extremely serious" one‑off incident to justify a PEX. Judge Edis concluded that neither the Headteacher nor the GDC expressly assessed whether the misconduct was "extremely serious" and that the misconduct (entering a teacher's room to recover the Appellant's own phone) was not reasonably characterised as "extremely serious" in light of the examples in the policies and Guidance.
    • Incorrect reliance on an allegation of burglary in the GDC's reconsideration letter: The reconsideration letter asserted the commission of a criminal offence (burglary under the Theft Act provisions), which required dishonesty. Judge Edis concluded this was a substantive and unjustified change of position introduced between the March hearing and the April reconsideration, unsupported by evidence and added after the IRP quashed the initial decision. He regarded the burglary assertion as central to some of the important conclusions (for example, assertions about threat to property and safety) and not merely a harmless error.
    • Failure adequately to consider alternatives: The GDC's justification for rejecting alternatives relied on the same defective process criticised by the IRP (an ex parte discussion with the Headteacher). Judge Edis considered that the reconsideration had not genuinely put right what the IRP identified as going wrong and that the minutes and reconsideration letter did not satisfactorily demonstrate that alternatives were considered afresh and lawfully.
  3. Consequence of findings:
    • Judge Edis concluded that (on the facts of this case) a decision that the conduct was "extremely serious" was not reasonably open to the GDC and thus the GDC's reconsideration decision was unlawful. He would allow the appeal on those bases.
    • He emphasised that his approach seeks to give effect to the statutory duty to follow Guidance and school policies and to require plain, intelligible reasons addressing how policies and Guidance were applied.

Judge Laing — Key reasoning (dismissing the appeal)

  1. Policy relationship and proper focus:
    • Analysed the relationship between the school's two policies and concluded the Exclusions & Suspension Policy (the governors' statement) tracked the statutory Guidance and was the relevant policy; the Behaviour Policy (headteacher's statement) must be read consistently with that framework.
    • Concluded it was unlikely that the school intended two divergent tests and that the governors were bound to apply the policy consistent with statutory Guidance.
  2. Standard of review and application:
    • Accepted that a heightened intensity of review is appropriate in permanent exclusion cases but emphasised the caution required so as not to substitute the court's view for that of decision‑makers with local knowledge and responsibility.
    • Found no error of law in the judge below's approach; characterised the appeal largely as a disagreement with evaluative assessments made by the judge below rather than demonstrable legal error.
  3. Assessment of the GDC's decision:
    • Concluded the GDC had applied the correct statutory test (limb 1 and limb 2) and had been entitled to find both limbs satisfied based on the facts as the governors saw them.
    • Regarded the GDC's erroneous reference to "burglary" as a mistake that did not materially change the substantive assessment that the Appellant had entered a teacher's room without permission; applied the section 31(2A) analytical approach to conclude the error was unlikely to have produced a substantially different outcome.
    • Rejected the submission that the judge below had failed to apply a heightened standard properly: she accepted the judge's statements that he applied a "high intensity of review" and found no legal misdirection.
  4. Conclusion:
    • Judge Laing would dismiss the appeal, concluding that the judge below had not erred in law and that the GDC's reconsideration was not irrational or unlawful on the grounds advanced.

Judge Arnold — Key reasoning (concurring with Judge Laing)

Judge Arnold emphasised three practical concerns: the personal consequences for the pupil, the GDC's clear error in referring to a criminal offence, and the court's obligation to avoid substituting its own view for the school's where statutory responsibility is vested in school decision‑makers. He agreed with Judge Laing that the appeal should be dismissed and concluded the judge below had not erred in law or principle in his overall approach.

Holding and Implications

Panel positions in the opinion:

  • Judge Edis: WOULD ALLOW the appeal — concluded the GDC's reconsideration decision was unlawful for failing to apply the Behaviour Policy threshold, for introducing an unjustified allegation of burglary, and for not adequately reconsidering alternatives.
  • Judge Laing: WOULD DISMISS the appeal — concluded the GDC had applied the statutory regime, any reference to burglary was a non‑decisive error under the section 31(2A) approach, and the judge below had applied the correct standard of review.
  • Judge Arnold: AGREED with Judge Laing (would dismiss the appeal).

Implications and immediate effects (as recorded in the opinion):

  • The three judges reached different conclusions; the opinion records the reasoning of each judge and the legal points they relied upon.
  • Because the judges are divided in their conclusions in the text provided, the summary above records each judge's stated disposition as given in the opinion. The opinion itself explains that the differing views have consequences for relief but does not, in the extract supplied, set out a single definitive order of the court as an agreed majority disposition.
  • No new general legal precedent was identified as being established by this decision beyond the application and discussion of established principles (statutory scheme, standard of review, process vs outcome rationality, and application of s.31(2A) where errors of law are present). The opinion applies existing authorities to the facts of the case.

Additional Observations Recorded in the Opinion

  • The IRP had quashed the initial GDC decision because of procedural impropriety (an ex parte discussion between the Headteacher and the governors) and directed reconsideration; the IRP also advised the GDC to articulate clearly any factors relied upon under the second limb.
  • The GDC's minutes of the first meeting recorded an initial view that permanent exclusion might be disproportionate, but a later private discussion with the Headteacher led to a change of view — a point central to the IRP's procedural criticism.
  • There is emphasis across the judgments that decision‑makers should produce clear, succinct reasons showing how statutory Guidance and school policies were applied, particularly when serious consequences flow from the decision.

Sources and Documents Referred to in the Opinion

The opinion repeatedly references the statutory provisions and guidance that established the legal framework for permanent exclusion:

  • Education Act 2002 (s51A)
  • Education and Inspections Act 2006 (ss88–89)
  • School Discipline (Pupil Exclusions) (England) Regulations 2012
  • Secretary of State's Guidance: "Suspension and permanent exclusion..." (published August 2024)
  • Company A's Exclusions & Suspension Policy (March 2024) and Behaviour Policy (October 2024)
