## PART A: RATIO DECIDENDI, OBITER DICTA & JUDICIAL REASONING

### 1. Identifying the Ratio Decidendi

The *ratio decidendi* is the legal reason for the decision — the rule of law on which the outcome depends. It is binding on lower courts in the hierarchy under the doctrine of *stare decisis*.

**Key distinction:**
- **Ratio**: the proposition of law necessary for the decision on the facts.
- **Obiter dicta**: things said by the way; persuasive but not binding.

**How to extract the ratio** (Wambaugh's inversion test): invert the proposition of law; if inverting it would change the result, the proposition is the ratio.

**Leading illustration — Donoghue v Stevenson [1932] AC 562 (House of Lords)**
Mrs Donoghue consumed ginger beer from an opaque bottle bought by her friend. She found the decomposed remains of a snail and became ill. She had no contract with the manufacturer and could not sue in contract.
- **Ratio**: A manufacturer owes a duty of care in tort to the ultimate consumer of their product where there is no contractual relationship, provided the product reaches the consumer in the same state as supplied. Lord Atkin's "neighbour principle": you must take reasonable care to avoid acts or omissions which you can reasonably foresee would be likely to injure your neighbour — persons so closely and directly affected by your act that you ought reasonably to have them in contemplation.
- **Obiter**: Lord Atkin's broader "neighbour principle" in its widest formulation extends beyond products. This wider statement was *obiter* but proved enormously influential.
- **Significance for legal method**: Illustrates how a wide general principle stated by a judge may be *obiter* while a narrower holding sufficient for the case is the binding *ratio*. Courts subsequently extracted different ratios (narrow product liability ratio vs broad neighbour principle).

**Caparo Industries plc v Dickman [1990] 2 AC 605 (House of Lords)**
Caparo acquired shares in Fidelity plc relying on statutory accounts audited by Touche Ross; the accounts were inaccurate. Caparo sued the auditors in negligence.
- **Ratio**: The three-stage test for duty of care: (i) reasonable foreseeability of damage; (ii) sufficient proximity between claimant and defendant; (iii) it must be fair, just and reasonable to impose a duty. Auditors preparing statutory accounts owe duties to the company and existing shareholders as a body, but **not** to individual shareholders making investment decisions or to potential investors — proximity was lacking.
- **Significance for legal method**: Demonstrates how the House of Lords reformulated (and effectively overruled) the earlier *Anns* two-stage test — showing the court's power to develop and restrict common law principles incrementally.

## PART B: DOCTRINE OF PRECEDENT (STARE DECISIS)

### 2. Hierarchy of Courts and Binding Precedent

Courts in England & Wales are bound by decisions of courts above them in the hierarchy:

| Court | Bound by | Binds |
|---|---|---|
| UK Supreme Court (UKSC) | Not strictly bound by itself (1966 Practice Statement) | All inferior courts |
| Court of Appeal | Bound by UKSC; bound by its own decisions (subject to Young v Bristol Aeroplane exceptions) | High Court and below |
| High Court | Bound by UKSC and CA | Inferior courts |
| Crown/County/Magistrates | Bound by all above | Not binding precedent |

### 3. The 1966 Practice Statement — HOL Power to Depart from Own Decisions

The House of Lords, in its 1966 Practice Statement, announced it would no longer treat its own previous decisions as absolutely binding where it appeared right to do so.

**British Railways Board v Herrington [1972] UKHL 1 (House of Lords)**
A six-year-old child was electrocuted after trespassing through a gap in the fence onto a railway line. Under *Addie v Dumbreck* [1929] AC 358, occupiers owed no duty of care to trespassers except not to injure them wilfully or recklessly.
- **Ratio**: The HOL departed from *Addie v Dumbreck* using the 1966 Practice Statement. Occupiers of land owe a duty of "common humanity" to child trespassers: where an occupier knows there is a real risk of trespassers being present, and has the means to remove or reduce the danger, they must take such steps as humane and conscientious people would take.
- **Significance**: A direct application of the 1966 Practice Statement — the HOL expressly overruled a binding precedent when it no longer reflected societal values about the treatment of child trespassers. Demonstrates that overruling is not the same as distinguishing.

**R v R [1991] UKHL 12 (House of Lords)**
A husband was convicted of rape of his wife. He argued the ancient common law immunity (stated in Hale's *History of the Pleas of the Crown*, 1736) prevented prosecution.
- **Ratio**: The common law marital rape immunity is abolished. The immunity lacked proper historical foundation (Hale's statement is unsupported by earlier authorities), and modern matrimonial law (which gives wives the right to divorce) had long destroyed the rationale. Courts are entitled to depart from a common law rule that was either always wrongly decided or whose underlying rationale has become obsolete.
- **Significance**: Central LA1031 authority on: (a) the HOL overruling / departing from a longstanding common law rule; (b) the Court of Appeal and HOL acting incrementally to achieve justice where an outdated rule produces unacceptable outcomes; (c) the interaction between judicial law-making and parliamentary sovereignty.

### 4. Binding Precedent Cannot Be Circumvented by Fictitious Distinction

**Church Commissioners for England v Meya [2006] EWCA Civ 821 (Court of Appeal)**
The question was the statutory interpretation of provisions governing periodic tenancies that succeed fixed-term tenancies, and whether *Laine v Cadwallader* was distinguishable.
- **Ratio**: Where a fixed-term tenancy is succeeded by a periodic tenancy under statute, the periods of the periodic tenancy are determined by reference to the periods for which rent was last payable under the fixed term. *Laine v Cadwallader* was binding on the Court of Appeal and could not be distinguished: the lower court must apply it.
- **Significance**: Illustrates the binding force of Court of Appeal precedent; lower courts must follow even where the result seems harsh, unless genuine grounds of distinction exist.

### 5. Parliamentary Sovereignty and the Courts

**British Railways Board v Pickin [1974] UKHL 1 (House of Lords)**
Mr Pickin argued a private Act of Parliament (British Railways Act 1968) was obtained by misrepresentation and should be declared invalid.
- **Ratio**: "It is not open to the court to go behind what has been enacted by the legislature, and to inquire how the enactment came to be made." Courts must accept an Act of Parliament as the law unless and until Parliament itself alters it. A court cannot declare an Act of Parliament invalid on the ground that Parliament was misled.
- **Significance**: Foundational authority for parliamentary sovereignty (Dicey's first element). Establishes that enrolled bill rule/parliamentary privilege prevents courts examining internal parliamentary proceedings. Critical for LA1031 essays on constitutional principles and sources of law.

## PART C: STATUTORY INTERPRETATION

### 6. The Rules of Statutory Interpretation

Four main approaches:
1. **Literal rule**: give words their plain, ordinary, grammatical meaning even if the result is absurd.
2. **Golden rule**: modify literal meaning to avoid absurdity — narrow (choosing between dictionary meanings) or wide (departing from literal to avoid repugnant result).
3. **Mischief rule** (*Heydon's Case* (1584)): courts ask what mischief the statute was enacted to remedy and interpret to suppress the mischief.
4. **Purposive approach**: identify the purpose/intention behind the legislation and interpret consistently with that purpose. Now dominant, especially post-HRA and under EU influence.

### 7. Judicial Application of Statutory Language — More Than Merely Preparatory

**R v Gullefer [1990] 1 WLR 1063 (Court of Appeal)**
Gullefer jumped onto a dog-racing track to stop the race and recover his stake; charged with attempted theft.
- **Ratio**: For criminal attempts under s.1(1) Criminal Attempts Act 1981, acts must be "more than merely preparatory to the commission of the offence." Lord Lane CJ: the defendant must have "moved from the realm of intention and preparation into the realm of execution." Jumping onto the track was merely preparatory; the defendant had not yet done any act forming part of the actus reus of theft.
- **Significance**: Illustrates statutory interpretation in practice — the Court had to interpret "more than merely preparatory" purposively to provide workable guidance. Demonstrates how courts give meaning to deliberately broad legislative language.

### 8. Statutory Interpretation — Fixed-Term Tenancy Succession

**Church Commissioners for England v Meya [2006] EWCA Civ 821**
(Also cited under precedent above.) The court interpreted the statutory provisions governing periodic tenancies: statutory language was applied using the ordinary/purposive meaning to fill a gap not expressly addressed, guided by the precedent in *Laine v Cadwallader*.

### 9. Human Rights Act 1998 — s.3 and s.4

**s.3 HRA 1998**: Courts must read and give effect to primary and subordinate legislation, so far as possible, in a way that is compatible with Convention rights.
**s.4 HRA 1998**: Where a court cannot interpret legislation compatibly with Convention rights (under s.3), a higher court may issue a **declaration of incompatibility**. This does not affect the validity, continuing operation, or enforcement of the legislation.

**Newby v Secretary of State for Justice [2019] EWHC 3118 (Admin)**
Mr Newby sought a declaration under s.4(2) HRA that s.2(1) of the Suicide Act 1961 (as amended) — which imposes a blanket prohibition on assisted suicide — is incompatible with Articles 2 and 8 ECHR.
- **Significance**: Illustrates the s.4 mechanism in practice — a claimant challenging the compatibility of primary legislation, requiring the High Court to examine whether a blanket legislative prohibition is disproportionate under Convention rights.
- **Key principle**: A s.4 declaration of incompatibility does not strike down the statute; legislative amendment is a matter for Parliament. Separation of powers is preserved.

**Procurator Fiscal v Brown [2000] UKPC D3 (Privy Council — devolution issue)**
The Procurator Fiscal sought to rely at trial on a compulsory admission obtained under s.172(2)(a) Road Traffic Act 1988. The respondent argued this breached Article 6 ECHR.
- **Ratio**: A compulsory admission obtained under statutory powers must be examined for compatibility with ECHR fundamental rights; where it breaches Art 6 (right to fair trial), the prosecution cannot rely upon it. The devolution issue was properly raised under the Scotland Act 1998.
- **Significance**: Demonstrates the HRA/convention compatibility analysis in practice; statutory provisions must be tested against Convention rights.

## PART D: COMMON LAW TRADITION AND CONSTITUTIONAL PRINCIPLES

### 10. Rule of Law

Dicey's three elements (from *Introduction to the Study of the Law of the Constitution*, 1885):
1. Supremacy of regular law — no one punished except for breach of law established in ordinary courts.
2. Equality before the law — all persons equally subject to ordinary law administered by ordinary courts.
3. Constitutional law as consequence — rights derived from judicial decisions, not guaranteed by formal bill of rights.

### 11. Judicial Procedure and Appellate Principles

**Osborn v Parole Board [2013] UKSC 61 (UK Supreme Court)**
Three prisoners challenged Parole Board decisions made on the papers without oral hearings.
- **Ratio**: The Parole Board must consider whether procedural fairness requires an oral hearing in each individual case, taking account of complexity and the potential impact on the prisoner's liberty. Neither a blanket policy of paper hearings nor a blanket policy of oral hearings is appropriate; the duty is context-sensitive. Rights to oral hearings arise under both the common law duty of procedural fairness and Article 5(4) ECHR where facts are disputed or character/risk is in issue.
- **Significance for LA1031**: Illustrates (a) the relationship between common law procedural fairness and ECHR rights; (b) the UKSC's role in developing the common law; (c) that HRA rights and common law rights often run in parallel.

**McGraddie v McGraddie [2013] UKSC 58 (UK Supreme Court)**
The UKSC reaffirmed the principle from *Thomas v Thomas* [1947] AC 484:
- **Ratio**: Appellate courts should not overturn a trial judge's findings of fact unless satisfied that the judge's advantage in seeing and hearing witnesses cannot explain the conclusion reached, or the judge plainly failed to use that advantage properly. Intervention is justified only in rare circumstances where the appellate court is convinced by the plainest considerations.
- **Significance**: Illustrates the appellate court hierarchy and the proper limits on appeals against findings of fact. Distinguishes questions of law (which appellate courts resolve afresh) from findings of fact (accorded high deference).

### 12. Causation and Judicial Reasoning

**Corr v IBC Vehicles [2008] UKHL 13 (House of Lords)**
Mr Corr suffered a workplace accident which led to clinical depression; he subsequently committed suicide. His widow sued under the Fatal Accidents Act 1976.
- **Ratio**: The employer was liable for the suicide. The suicide did not break the chain of causation (*novus actus interveniens*): it was a foreseeable consequence of the psychiatric injury caused by the employer's negligence. No reduction for contributory negligence.
- **Significance**: Demonstrates judicial reasoning in the HOL — examining causation principles in a multi-step causal chain, considering foreseeability, *novus actus*, and policy. Also illustrates how landmark cases are built on preceding authority (the court applied the neighbour/duty framework from *Donoghue v Stevenson*).

### 13. Duty of Care — Extension to Public Authorities

**Home Office v Dorset Yacht Co [1970] AC 1004 (House of Lords)**
Borstal officers allowed seven young offenders to escape; the offenders damaged yachts belonging to Dorset Yacht Co.
- **Ratio**: Public authorities are not immune from negligence liability. The Home Office owed a duty of care (on a preliminary issue) to those foreseeably likely to be harmed by the escape of offenders in their custody. Lord Reid explicitly extended the *Donoghue v Stevenson* neighbour principle to public authority defendants.
- **Significance**: Illustrates incremental development of common law precedent — the HOL extending the *Donoghue* ratio to a new category of defendant, demonstrating the case-by-case method of common law development.

## EXAM TECHNIQUE NOTES

**Seen Case (Part A):** Identify parties, court, year, citation. Extract ratio using the Wambaugh test. Distinguish ratio from obiter — is the statement necessary for the decision? Analyse reasoning — inductive/deductive? Policy-based? Statutory construction?

**Essays (Part B):** Always cite a real case + citation for every legal proposition. Distinguish overruling (a higher court departs from its own/lower decision) from distinguishing (a court finds the material facts differ). Use *BRB v Herrington* and *R v R* for overruling; *Church Commissioners v Meya* for distinguishing.

**Seen Statute (Part C):** Apply the rules in sequence — literal first; then golden if absurdity; mischief/purposive where context demands. Check HRA s.3 compatibility. Use *R v Gullefer* as a worked illustration.
