KembaraXtra-Case Law-Chatterton v Gerson (1981)
This case clarifies the crucial link between a doctor's negligent failure to disclose information and a patient's resulting harm. Simply proving negligence (breaching the standard of care by failing to disclose) isn't enough; the patient must also demonstrate that had the information been disclosed, they would have made a different decision.
I. Core Principle:
The claimant (patient) needs to prove a causal link between the doctor's failure to disclose and their harm. This isn't merely about whether they say they would have acted differently, but whether that claim is credible.
II. The "But For" Test (Subjective, Objectively Tested):
The legal test for causation hinges on the "but for" principle: "But for the doctor's breach of duty (failure to disclose), would the claimant have still undergone the procedure?"
Subjective Element: The court considers the patient's individual perspective. What would this specific patient have done with full information? Their honest belief is crucial.
Objective Element: However, the court assesses the credibility of the patient's subjective claim objectively. This means the court scrutinizes the patient's testimony against all available evidence (severity of the condition, alternative treatments, etc.) to determine if their stated decision is likely true or a retrospective rationalization.
III. Key Case Law:
Chatterton v Gerson (1981): Bristow J established the principle that the claimant must prove they would not have undergone the operation if the duty of disclosure had been fulfilled.
Hills v Potter (1984): This case further exemplifies the objective element. Even though the patient sincerely believed she would have declined the operation with full disclosure, the judge found it more likely than not that she would have proceeded given the severity of her condition. This highlights that sincere belief alone isn't sufficient; the court must be persuaded by the evidence.
IV. Study Questions:
Explain the two-part test for causation in medical negligence cases stemming from a failure to disclose information. How do the subjective and objective aspects interact?
How does Hills v Potter illustrate the importance of objective assessment of the patient's claim even when they genuinely believe they would have made a different decision?
What would constitute sufficient evidence to persuade a court that a patient would have acted differently had the necessary information been disclosed? Consider factors such as the severity of the condition, available alternatives, and the patient's personality and risk tolerance.
Why is it important that the test for causation is subjective, constrained by an objective test of credibility? What problems would arise if only a subjective test were applied? What problems would arise if only an objective test were applied?
By understanding these points and answering the study questions, you'll gain a firm grasp of the legal principles governing causation in medical negligence cases involving failure to disclose. Remember to focus on the interplay between the subjective belief of the patient and the objective assessment of the court.
