Introduction
The legal framework governing clinical negligence in the UK has evolved significantly over the past few decades, particularly in relation to the standard of care owed by medical professionals to their patients. Historically, the “professional practice test,” established in Bolam v Friern Hospital Management Committee [1957] 1 WLR 582, has been the cornerstone for determining breach of duty in diagnosis and treatment, allowing doctors to avoid liability if their actions align with a responsible body of medical opinion. However, subsequent cases, notably Bolitho v City and Hackney Health Authority [1998] AC 232 and Montgomery v Lanarkshire Health Board [2015] UKSC AC 1430, have reshaped this framework, introducing patient autonomy and informed consent as critical considerations in a doctor’s advisory role. The recent Supreme Court decision in McCulloch v Forth Valley Health Board [2023] UKSC 26 has further refined the application of these principles, particularly concerning the scope of reasonable treatment options in the context of informed consent. This essay examines whether the McCulloch decision makes it more challenging for patients to prove breach of duty in clinical negligence cases. By analysing key developments in case law since 2015 and drawing on academic commentary, it explores the evolving judicial approach to breach of duty and its implications for patients seeking redress.
The Pre-2015 Framework: Bolam and Bolitho
The foundational test for clinical negligence, commonly referred to as the “professional practice test,” was articulated by McNair J in Bolam v Friern Hospital Management Committee (1957) at p. 587. This test posits that a doctor is not negligent if their conduct aligns with a practice accepted as proper by a responsible body of medical opinion, even if other practitioners might adopt a different approach. This principle, consistent with the Scottish case of Hunter v Hanley 1955 SC 200, prioritised professional judgment over external standards, often making it difficult for patients to succeed in claims unless the doctor’s actions demonstrably deviated from accepted norms (Herring, 2018).
However, the decision in Bolitho v City and Hackney Health Authority (1998) introduced a significant qualification. The House of Lords held that courts are not bound to accept professional opinion as conclusive if it fails to withstand logical analysis. This marked a subtle shift, empowering courts to scrutinise medical opinion more critically, though such interventions remain rare (Kennedy and Grubb, 2000). Indeed, Bolitho did not fundamentally alter the deference to medical expertise but provided a mechanism for judicial oversight in exceptional cases. This framework set the stage for further developments, particularly concerning the advisory role of doctors, as seen in subsequent landmark cases.
The Impact of Montgomery: A Shift Towards Patient Autonomy
The 2015 Supreme Court decision in Montgomery v Lanarkshire Health Board represented a transformative moment in clinical negligence law, particularly regarding the doctor’s advisory role in treatment decisions. Departing from the Bolam test, the court ruled that doctors must take reasonable care to ensure patients are informed of material risks associated with recommended treatments, as well as any reasonable alternatives (para 87). The judgment emphasised patient autonomy, recognising that the decision to accept risks ultimately lies with the patient, not the doctor (Montgomery, 2015). This shift imposed a duty of disclosure that could, in some instances, go beyond what a responsible body of medical opinion might deem proper, thus arguably making it easier for patients to establish a breach of duty in cases involving inadequate information provision (Farrell and Devaney, 2015).
Academic commentary has largely welcomed the Montgomery decision for promoting shared decision-making. For instance, Miola (2015) argues that it aligns medical law with modern ethical standards, prioritising individual rights over paternalistic traditions. However, others caution that the broader duty of disclosure may burden clinicians with unrealistic expectations, especially in complex cases where defining “material risks” remains subjective (Chan, 2016). Nonetheless, Montgomery undeniably expanded the scope for patients to claim negligence based on failures in communication rather than purely technical errors in treatment or diagnosis.
McCulloch v Forth Valley Health Board: Refining the Montgomery Principle
The Supreme Court’s ruling in McCulloch v Forth Valley Health Board [2023] UKSC 26 directly addresses the scope of reasonable alternative treatments under the Montgomery framework, raising questions about whether it imposes a stricter standard for patients claiming breach of duty. In this case, the court considered whether a doctor is obliged to inform a patient of all possible alternative treatments or only those that a responsible body of medical opinion would endorse as reasonable. The majority judgment held that the duty to disclose alternatives is limited to treatments that align with professional practice, effectively reinstating elements of the Bolam test in the advisory context (para 58). Consequently, doctors are not required to discuss options deemed unreasonable by their peers, even if a patient might consider them relevant (Herring, 2023).
This decision arguably narrows the scope of disclosure obligations established in Montgomery. By tying the duty to inform back to professional standards, McCulloch potentially reduces the range of information doctors must provide, making it more challenging for patients to argue that a failure to disclose a particular alternative constitutes a breach of duty (Jones, 2023). For example, if a treatment is unconventional or unsupported by a responsible body of medical opinion, a doctor may justifiably withhold discussion of it, even if the patient might have valued knowing about it. This approach could shield clinicians from liability in cases where their judgment aligns with professional norms, thereby raising the evidential threshold for patients.
Does McCulloch Make Proving Breach of Duty More Difficult?
The central question of whether McCulloch makes it more difficult for patients to prove breach of duty elicits mixed perspectives. On one hand, the decision can be seen as a pragmatic clarification that balances patient autonomy with the realities of medical practice. By limiting the duty of disclosure to professionally endorsed options, it prevents doctors from being overwhelmed by the expectation to discuss every conceivable alternative, many of which may lack clinical merit (Brazier and Cave, 2023). This view suggests that McCulloch does not fundamentally undermine patient rights but rather refines them within a feasible framework.
On the other hand, critics argue that tying disclosure obligations to professional standards risks diluting the patient-centric ethos of Montgomery. As Montgomery and Miola (2023) note, this approach may exclude patients from meaningful participation in decisions about their care, particularly where unconventional treatments or personal values are at play. Moreover, proving that a doctor failed to disclose a “reasonable” alternative now requires patients to navigate the nuances of medical opinion, a task that often demands expert testimony and significant resources (Farrell and Devaney, 2023). Therefore, while McCulloch provides clarity for clinicians, it arguably places a heavier burden on claimants to demonstrate that an undisclosed option was both reasonable and material to their decision-making.
Broader Implications for Clinical Negligence Law
The evolution from Montgomery to McCulloch reflects a judicial attempt to balance competing interests: the right of patients to make informed choices and the need to maintain a practical standard of care for medical professionals. While Montgomery prioritised individual autonomy, McCulloch reintroduces deference to professional judgment, suggesting that courts remain cautious about imposing overly burdensome duties on doctors. This trajectory indicates a nuanced judicial approach, recognising that clinical negligence law must adapt to societal expectations of patient involvement without compromising the integrity of medical expertise (Herring, 2023).
Furthermore, the reliance on professional opinion in McCulloch underscores ongoing challenges in defining “reasonable” alternatives. Courts may need to grapple with divergent expert views, particularly in rapidly evolving fields of medicine where consensus is elusive. As such, patients face not only legal but also evidential hurdles in establishing breach of duty, potentially limiting access to justice in complex cases (Jones, 2023).
Conclusion
In conclusion, the Supreme Court decision in McCulloch v Forth Valley Health Board (2023) arguably makes it more difficult for patients to prove breach of duty in clinical negligence cases by narrowing the scope of disclosure obligations to professionally endorsed alternatives. While Montgomery (2015) marked a progressive shift towards patient autonomy by imposing broader duties of information provision, McCulloch reintroduces elements of the Bolam test, prioritising professional judgment over individual preferences in certain contexts. Although this approach offers clarity and protection for clinicians, it places a higher evidential burden on patients, who must demonstrate that undisclosed options were both reasonable and material. The development of clinical negligence law since 2015 reflects a delicate balancing act between respecting patient rights and acknowledging the practical constraints of medical practice. Looking forward, further judicial or legislative clarification may be necessary to ensure that the law adequately addresses the complexities of informed consent while maintaining equitable access to redress for patients.
