Exam use

In an exam, introduce Gregg v. Scott with the citation only if you can remember it accurately; otherwise use the case name and court, then focus on the rule and application. A strong answer should say what Gregg v. Scott decided, why the facts mattered, and how the authority helps resolve the new facts. Avoid treating the case as a decorative reference. Use it to prove a doctrinal step in Negligence – loss of chance / causation, then move quickly to analysis.

Summary

Gregg v. Scott is included in the Torts case database because it gives students a concrete authority for Negligence – loss of chance / causation. The reported citation is [2005] UKHL 2, [2005] 2 AC 176, and the decision is associated with House of Lords. In revision, treat the case as a way to connect the legal issue to a real dispute rather than as an abstract rule. The key exam move is to state the holding, identify the fact pattern that made the rule matter, and then decide whether a new problem question should apply, distinguish, or limit the authority.

Facts

The material factual signal for Gregg v. Scott is: The defendant doctor negligently failed to diagnose a lump, delaying treatment for cancer; the plaintiff's chance of survival fell from about 42% to 25%. Students should read the linked source and turn that signal into a short fact table: parties, transaction or public-law setting, procedural posture, conduct in dispute, and the fact the court treated as decisive. This prevents vague case-dropping. In an answer on Torts, use the facts to explain why Negligence – loss of chance / causation was live, then compare the problem facts against the facts in the case before stating any conclusion.

Procedural History

Gregg v. Scott is reported as a decision of House of Lords. The procedural route should be checked against the linked source before formal citation. For study notes, record whether the decision was an appeal, judicial review, trial judgment, tribunal ruling, or constitutional/application proceeding, because that posture affects how confidently the rule can be used.

Ratio Decidendi

Loss of chance is not generally compensable in medical negligence cases unless the chance of a favourable outcome was more than 50% (the traditional but-for test applies).

Obiter Dicta

Check the linked source for concurring, dissenting, or obiter observations before quoting this case. If the case includes non-binding reasoning, use it as persuasive support rather than as the core rule.

Reasoning

For reasoning, start with the ratio: Loss of chance is not generally compensable in medical negligence cases unless the chance of a favourable outcome was more than 50% (the traditional but-for test applies). Then read the source and separate three things: the legal test, the facts used to apply that test, and any policy or institutional reason the court gave. This structure makes Gregg v. Scott easier to use in essays and problem questions. In Torts, the case should be compared with related authorities on Negligence – loss of chance / causation; if the jurisdiction, statute, or procedural posture differs from the exam problem, explain that limit explicitly instead of treating the authority as automatic.

Plain-English Explanation

Plainly, Gregg v. Scott is a case to use when a Torts answer needs an authority on Negligence – loss of chance / causation. Do not just list it. Explain the problem the court had to solve, the rule or holding it used, and the fact that made the result persuasive. That turns the case from a memorised name into evidence for your legal analysis.
