Judicial Review of Regulatory Guidance: “Misdirection in Law” Requires Inducement of Unlawful Conduct (R(A) Applied to Terminology in GMP)

1. Introduction

This Court of Appeal decision concerns a targeted public law challenge brought by the British Medical Association (“BMA”) against the General Medical Council (“GMC”) regarding the GMC’s use of the collective term “medical professionals” in its core standards guidance Good Medical Practice (“GMP”).

Following the Anaesthesia Associates and Physician Associates Order 2024 (“the AAPA Order”), the GMC became regulator not only of doctors under the Medical Act 1983 (“the 1983 Act”), but also of physician associates (“PAs”) and anaesthesia associates (“AAs”). The BMA originally challenged (i) the terminology “medical professionals” and (ii) the “unitary guidance” approach (one standards document for doctors and associates). The unitary guidance challenge fell away on appeal. The appeal therefore focused on whether use of “medical professionals” was unlawful, irrational, or frustrated statutory purpose, and whether the claim was out of time.

The Court dismissed the appeal, holding that the terminology was lawful; that the BMA’s attempt to frame the issue as “misdirection in law” failed because the term neither misstated the law nor induced unlawful conduct; and that the judicial review was brought too late without good reason for an extension.

2. Summary of the Judgment

  • Ground 1 (lawfulness/misdirection): The term “medical professionals” is not a protected title, is not defined in the 1983 Act, and its use (clearly explained as a collective label for GMC registrants) does not misstate the law or encourage unlawful conduct (including any breach of s.49 of the 1983 Act). The Court endorsed the judge’s approach of analysing alleged legal inconsistency in policy guidance through the framework in R(A) v Secretary of State for the Home Department [2021] UKSC 37.
  • Ground 2 (independent Padfield/Wednesbury challenge): The GMC’s decision-making and reasons (clarity/readability; accurate umbrella term; consultation history) were rational and aligned with statutory objectives. Post-decision internal terminology guidance did not undermine the legality or rationality of the original decision.
  • Ground 3 (extension of time): The claim was not brought promptly or within three months of the relevant decision, and no good reasons justified extension. Later revisions to GMP did not reset time in respect of an unchanged feature.
  • Academicness: The appeal was not academic. The Leng Review related primarily to the (abandoned) unitary guidance issue, not to the “medical professionals” terminology issue remaining on appeal.

3. Analysis

3.1 Precedents Cited

(a) Policy/guidance unlawfulness and “misdirection in law”

The Court treated Gillick v West Norfolk and Wisbech Area Health Authority [1986] AC112 as the classic starting point for challenging guidance: a policy may be unlawful if it permits or encourages unlawful conduct by those who follow it. The Court emphasised Lord Scarman’s formulation (as later clarified), and the warning against demanding policy drafts eliminate every risk of misreading.

The doctrinal centre of gravity was R(A) v Secretary of State for the Home Department [2021] UKSC 37 ("R(A)"). The Court relied on R(A)’s categorisation of when guidance may be unlawful for legal error:

  • Category (i): a positive statement of law that is wrong and induces breach of a legal duty (Gillick-type).
  • Category (ii): failure to provide accurate legal advice where there is a duty to do so.
  • Category (iii): where guidance purports to give a full legal account but is misleading by misstatement/omission.

Importantly, the Court rejected the BMA’s attempt to avoid R(A) by asserting a free-standing unlawfulness standard of “inconsistency with the statutory framework”. The Court held that if a claimant alleges a “misdirection in law” in guidance, it must be anchored to a recognised public law test, and in this context R(A) provides the relevant analytical structure.

The Court reinforced that approach by reference to R(BF) Eritrea v Home Secretary [2021] UK SC38; [2021] 1WLR 3967, where the Supreme Court reiterated that the primary obligation (the “Gillick obligation”) is not to direct recipients to act contrary to legal duty, and there is no general duty to draft guidance so as to remove every risk of misapplication.

The Court also cited R (Letts) v Lord Chancellor (Equality and Human Rights Commission intervening) [2015] EWHC 402 (Admin); [2015] 1 WLR 4497 ("Letts") (via R(A)) to show that lawfulness does not require exhaustive detail; broad signposts can be enough. It cited R (Timson) v SSWP [2022] EWHC 2392 (Admin) for the point that R(A)’s categories are not rigid boxes, but remain a helpful guide.

The Court distinguished R (CPH) v SSHD [2025] EWHC 848 (Admin) as not being “concerned with statements of law at all”, and therefore not supporting an alternative test.

Finally, in addressing the danger of inventing free-floating new rubrics, the Court invoked R v Secretary of State for the Home Department ex parte Oladhinde [1990] 1AC 254 to caution against over-compartmentalisation—while insisting there must still be a stable legal foundation for review.

(b) Rationality and statutory purpose (Wednesbury and Padfield)

The Court restated the orthodox rationality test from Associated Provincial Picture Houses Limited v Wednesbury Corporation [1948] 1 KB 223. It relied on R(Law Society) v Lord Chancellor [2018] EWHC 2094 (Admin); [2019] 1WLR 1659 (Leggatt LJ) for the distinction between (i) irrational outcomes and (ii) irrationality as a flaw in reasoning/process (e.g., reliance on irrelevant considerations or evidential gaps).

For improper purpose/frustration of statutory policy, the Court applied Padfield & Ors v Ministry of Agriculture, Fisheries and Food [1968] A.C.997, and noted the reformulation in Braintree DC Ex Parte Halls (2000) 32 H.L.R. (Laws LJ), while observing that any nuance between “frustration” and “promotion” was immaterial on these facts.

(c) Promptness and extensions of time

The Court applied CPR 54.5(1) (promptness/three months), citing R v Department of Transport Ex Parte Presvac Engineering [1992] 4 Admin LR 121 for the general rule that time runs from the date of the decision (subject to later notification).

It relied on Maharaj v National Energy Corporation of Trinidad and Tobago [2019] UKPC 5; [2019] 1WLR 983 for the correct test: not merely “good reason for delay” but “good reasons for extending time”, encompassing merits, prejudice/detriment and public interest. It noted the authorities referenced within Maharaj, including Greenpeace 2 [200] Env LR 221 and Manning v Sharma [2009] UKPC 37.

3.2 Legal Reasoning

(a) Why the “medical professionals” label was not unlawful

The Court’s reasoning is doctrinally significant in how it constrains judicial review of regulatory language:

  • Not a legal term; not a “positive statement of law”: “Medical professionals” is not defined in the 1983 Act, nor a statutorily protected title. The Court held that using the term in GMP therefore did not amount to a statement of law capable of being “wrong” in the R(A) category (i) sense.
  • No inducement/encouragement of unlawful conduct: The legal risk posited by the BMA centred on s.49 (criminal offence of falsely implying one is registered as a doctor/medical practitioner). The Court held there was “an unbridgeable gap” between using a collective umbrella term for registrants and inducing a “wilful and false” pretence of being a doctor. GMP also expressly requires honesty about role (point 82), which cuts against any implication of masquerading as a doctor.
  • Read the document as a whole and in context: The Court stressed that the term is explained upfront: it is used to describe “all our registrants” addressed as “you”. This contextual reading is consistent with R(A)/Gillick’s insistence on objective, overall reading rather than isolated snippets.
  • Accuracy of ordinary language matters: The Court endorsed the unappealed finding that PAs and AAs are “fairly described as medical professionals” in ordinary language, even though they are not doctors.

(b) Patient confusion: evidential “targeting” and causal fit

A notable feature of the judgment is its insistence on causal fit between evidence and the challenged act. The Court accepted evidence of patient confusion and safety concern as real, but held that it related to the public’s limited understanding of the associate roles, not to the umbrella label “medical professionals”. Because “associate” is the term used by Parliament in the AAPA Order and not controlled by the GMC, the Court treated the BMA’s complaint as misdirected: the evidence did not show the challenged label itself caused the confusion that was relied upon.

(c) Ground 2: why Padfield and Wednesbury failed even as a process challenge

The Court confirmed that an independent challenge to the process of choosing terminology requires showing a genuine flaw in reasoning (per the approach in R(Law Society) v Lord Chancellor [2018] EWHC 2094 (Admin); [2019] 1WLR 1659). It held there was no such flaw: the GMC considered alternatives (“registrant” as “cold and impersonal”; other terms with over-breadth issues), consulted widely, and used the term as a readability device for registrants.

The Court rejected the “hangover from abandoned legislation” narrative. The term predated the shelved “Medical Professions Order 2022” initiative (first used in 2020), and the consultation materials showed the GMC said the term would “also” be used in legislation, not that it was compelled to use it. Even if the GMC had aligned with anticipated legislative language, the Court considered that alignment could not sensibly be characterised as irrational.

The Court treated the later internal terminology guidance (“use with caution”; avoid in patient-facing communications) as (i) post-dating the decision and therefore not evidencing defect at the time, and (ii) consistent with the key conceptual distinction the Court drew: “medical professionals” is not the same as “the medical profession”.

(d) Ground 3: time does not restart for unchanged features in later revisions

On promptness, the Court held that by August 2023 at the latest the BMA knew a decision had been taken to use “medical professionals” and could have challenged promptly. A later confirmation of the GMC’s regulatory role via the AAPA Order did not change the character of the decision, since the guidance development had proceeded on the (correct) assumption that the GMC would regulate associates.

The Court’s most practically important point is that later revisions do not “reset the clock” for judicial review of an unchanged element. Otherwise, any minor revision could re-open limitation for old issues, undermining legal certainty and good administration.

3.3 Impact

  • Guidance challenges are constrained by “inducement of unlawfulness”: The decision reinforces that challenges to non-statutory or statutory guidance framed as “misdirection in law” will generally need to fit within the Gillick/R(A) framework—showing actual normative inconsistency that permits/encourages unlawful conduct or presents a legally misleading picture where the document purports to be legally comprehensive.
  • Regulators gain latitude over “labels” where properly explained: If a collective descriptor is not a protected title, is linguistically accurate, and is accompanied by clear explanation and honesty duties, courts are unlikely to treat it as public-law actionable—even amid wider controversies about role boundaries.
  • Evidence must match the pleaded target: Claimants will need to show that the specific impugned term (not adjacent policy disputes) causes the alleged harm, especially where confusion may arise from statutory terminology outside the regulator’s control.
  • Limitation/promptness discipline is strengthened: The Court’s reasoning discourages tactical delay in anticipation of later policy iterations. An unchanged issue should be challenged when first crystallised.

4. Complex Concepts Simplified

  • Judicial review: a court challenge to the legality of decisions/actions by public bodies, focusing on lawfulness, fairness, and rationality—not the “best” policy choice.
  • Policy/guidance unlawfulness (Gillick/R(A)): guidance is usually unlawful only if it effectively directs or encourages unlawful behaviour, or (in some contexts) gives a misleading legal picture where it claims to set out the law.
  • Protected title (s.49 of the 1983 Act): certain medical titles/implications are legally restricted; falsely implying one is a registered doctor can be a criminal offence. “Medical professional” is not a protected title.
  • Padfield principle: a discretion can be unlawful if exercised to frustrate the purpose of the statute conferring it (improper purpose/defeating statutory policy).
  • Wednesbury irrationality: a very high threshold; a decision is unlawful only if it is outside the range of reasonable responses, or if there is a serious reasoning/process flaw (irrelevant factors, evidential gaps).
  • Promptness/three months (CPR 54.5): judicial review must be brought promptly and within three months. Extensions depend on “good reasons” (including merits and prejudice), not merely explanation for delay.
  • Rolled-up hearing: a hearing where permission and the substantive claim are dealt with together.

5. Conclusion

The Court of Appeal’s decision confirms a disciplined approach to challenges against regulatory guidance, especially where the complaint concerns terminology rather than a concrete legal direction. By applying R(A) v Secretary of State for the Home Department [2021] UKSC 37 ("R(A)") to the GMC’s GMP, the Court effectively held that allegations of “misdirection in law” must be tethered to recognised public law wrongs—most centrally, guidance that permits/induces/encourages unlawful conduct or is legally misleading in a way that matters.

On the facts, “medical professionals” was a non-protected, linguistically accurate umbrella term, clearly defined as referring to GMC registrants and counterbalanced by explicit duties of honesty about role. Evidence of wider patient confusion did not establish unlawfulness because it did not show that this term (as opposed to the statutory “associate” nomenclature and broader role issues) caused the harm asserted. Procedurally, the decision underscores that litigants must act promptly and cannot rely on later policy iterations to revive time limits for an unchanged issue.
