Master stare decisis and judicial precedent: ratio decidendi vs obiter dicta, binding vs persuasive authority, court hierarchy, and when courts can depart from precedent.

Stare Decisis and Judicial Precedent in South African Law

Area of Law: Jurisprudence & Sources of Law
Reading Time: 10 minutes

🎯 What is Stare Decisis?

Stare decisis = Latin for "to stand by things decided"

Core principle: Courts follow previous decisions of higher courts on the same legal issue.

Why it matters:

  • Legal certainty (predictability)
  • Consistency (like cases treated alike)
  • Efficiency (don't re-argue settled issues)
  • Fairness (established rules apply equally)

📖 The Doctrine of Precedent

How It Works

When a court decides a case:

  1. Court states legal principle (ratio decidendi)
  2. Principle becomes precedent
  3. Lower courts must follow that principle in future cases

Example:

S v Makwanyane (1995):

  • Ratio: Death penalty violates Sections 10 and 11
  • Effect: All courts must follow — death penalty unconstitutional
  • Binding: Cannot impose death penalty in any case

📖 The Court Hierarchy

Vertical Binding

Higher courts bind lower courts:

┌────────────────────────────┐
│  CONSTITUTIONAL COURT      │ ← Highest on constitutional matters
└────────────┬───────────────┘
             │ BINDS ↓
┌────────────────────────────┐
│  SUPREME COURT OF APPEAL   │ ← Highest on non-constitutional appeals
└────────────┬───────────────┘
             │ BINDS ↓
┌────────────────────────────┐
│  HIGH COURTS               │ ← Provincial/Division Benches
└────────────┬───────────────┘
             │ BINDS ↓
┌────────────────────────────┐
│  MAGISTRATES' COURTS       │ ← District and Regional
└────────────────────────────┘

Binding Precedent Examples

Example 1: Constitutional Court

Constitutional Court decides:

"Section 25 does not require compensation for all expropriations — only equitable compensation considering all relevant factors."

Effect:

  • Supreme Court of Appeal MUST follow
  • High Courts MUST follow
  • Magistrates' Courts MUST follow

Example 2: Supreme Court of Appeal

SCA decides:

"Malice is required for defamation liability."

Effect:

  • High Courts MUST follow
  • Magistrates' Courts MUST follow
  • BUT Constitutional Court NOT bound (can overrule on appeal)

Horizontal Precedent

Same-level courts:

  • Not strictly bound
  • Persuasive authority
  • Generally followed for consistency

Example:

  • Gauteng High Court decision
  • Persuasive (not binding) on Western Cape High Court
  • Western Cape HC may follow but not obliged

📖 Ratio Decidendi vs Obiter Dicta

Ratio Decidendi (The Binding Part)

Ratio decidendi = the legal principle necessary to decide the case

Characteristics:

  • Binding on lower courts
  • Forms the precedent
  • Must be followed in future similar cases

How to identify:

  1. What was the legal question?
  2. What legal principle did the court apply to answer it?
  3. Was that principle necessary for the decision?

Example: S v Makwanyane (1995)

Facts: Challenge to death penalty

Legal question: Does death penalty violate Constitution?

Ratio decidendi:

"The death penalty violates the right to life (Section 11) and dignity (Section 10). It is unconstitutional."

Effect: BINDING — no court may impose death penalty

Obiter Dicta (Persuasive Comments)

Obiter dicta = comments not necessary for the decision

Characteristics:

  • Persuasive (not binding)
  • May be followed but not required
  • Often indicates court's view on related issues

Types:

  1. Hypothetical reasoning ("If the facts were X, we would hold Y")
  2. Alternative grounds not relied on
  3. General comments on law
  4. Discussion of academic views

Example: S v Makwanyane (1995)

Obiter dicta:

  • Discussion of ubuntu philosophy
  • Comparative analysis of foreign death penalty cases
  • Comments on retribution vs rehabilitation

Effect: PERSUASIVE — courts often cite ubuntu discussion, but not binding

How to Distinguish Ratio from Obiter

Ask:

  1. Remove the statement — would the decision be the same?
  2. If YES (decision same) → obiter (not necessary)
  3. If NO (decision changes) → ratio (necessary)

Example:

Court says:

  1. "Defamation requires publication" — ratio (essential element)
  2. "We note social media raises new issues" — obiter (interesting but not necessary)

📖 When Courts Can Depart from Precedent

Constitutional Court

Can depart from own precedent if:

  • Earlier decision wrong
  • Societal values changed
  • Constitution better interpreted differently

Key case: Investigating Directorate v Hyundai (2001)

  • Overruled earlier decision on admissibility of evidence
  • Held previous interpretation of Section 35(5) incorrect

Principle: Constitutional Court not bound by own decisions (can overrule itself).

Supreme Court of Appeal

Generally bound by own precedent unless:

  • Full bench (more judges) overrules earlier decision
  • Constitutional Court overrules SCA precedent
  • Earlier decision clearly wrong

Key case: Johannesburg Municipality v D Steward & Co (1909)

  • Established SCA (then Appellate Division) may depart from own decisions in exceptional circumstances
  • Rare — promotes stability

High Courts

Bound by:

  • Constitutional Court
  • Supreme Court of Appeal

Not bound by:

  • Own previous decisions (can depart)
  • Other High Court divisions (persuasive only)

Example:

  • Western Cape High Court can depart from own earlier decision
  • But cannot depart from Constitutional Court or SCA

📖 Distinguishing Cases

When Precedent Doesn't Apply

Distinguishing = showing current case is materially different from precedent.

If distinguished:

  • Precedent doesn't apply
  • Court free to decide differently

How to Distinguish

Identify material differences:

  1. Different facts (legally significant)
  2. Different legal issue
  3. Different statute or constitutional provision
  4. Different context

Example: Contract Cases

Precedent case:

  • Facts: Written contract, clear terms
  • Held: Parol evidence inadmissible

Current case:

  • Facts: Oral contract, disputed terms
  • Distinction: Parol evidence rule applies to written contracts, not oral
  • Result: Precedent doesn't apply — distinguished

📖 Overruling vs Distinguishing vs Departing

Overruling

Higher court declares lower court precedent wrong.

Example:

  • Constitutional Court overrules Supreme Court of Appeal decision
  • SCA decision no longer good law

Distinguishing

Any court shows precedent doesn't apply because facts/issues different.

Example:

  • High Court distinguishes SCA decision
  • SCA decision still good law, just doesn't apply here

Departing

Court departs from own earlier decision.

Example:

  • Constitutional Court overrules own earlier judgment
  • Earlier CC judgment no longer good law

📖 Persuasive Precedents

Not Binding But Influential

Sources of persuasive precedent:

  1. Foreign courts (especially Commonwealth jurisdictions)
  2. Same-level courts (e.g., other High Court divisions)
  3. Academic writing (textbooks, journals)
  4. Obiter dicta from higher courts
  5. Dissenting judgments

Foreign Precedent

Section 39(1)(c):

"When interpreting the Bill of Rights, a court... may consider foreign law."

Why persuasive?

  • Similar constitutional systems (Canada, India, Namibia)
  • Well-reasoned judgments
  • Universal human rights principles

Key case: S v Makwanyane (1995)

  • Extensively cited US, Canadian, German, Indian death penalty cases
  • Persuasive (not binding)
  • Helped interpret Sections 10 and 11

Academic Writing

Textbooks and journal articles:

  • Persuasive authority
  • Courts cite leading scholars
  • Especially influential in developing common law

Example: Barkhuizen v Napier (2007)

  • Court cited Hutchison's article on pacta sunt servanda
  • Persuasive in developing common law contract principles

📖 Practical Application

Example Problem

Scenario:

Precedent case (Supreme Court of Appeal):

  • Employee dismissed for dishonesty
  • Held: Dishonesty always justifies dismissal

Current case (Magistrates' Court):

  • Employee took company pen worth R5
  • Employer seeks to rely on SCA precedent

Question: Is magistrate bound?

Analysis

Step 1: Identify hierarchy

  • SCA decision binds Magistrates' Court ✓

Step 2: Check if ratio or obiter

  • "Dishonesty always justifies dismissal" — appears to be ratio

Step 3: Can it be distinguished?

  • Precedent: Serious dishonesty (theft of R50,000)
  • Current case: Trivial dishonesty (R5 pen)
  • Material difference? YES — proportionality matters in labour law

Conclusion:

  • Magistrate can distinguish precedent
  • Precedent dealt with serious dishonesty
  • This case: trivial breach, dismissal disproportionate
  • Precedent doesn't apply — distinguished

💡 Exam Strategy

Spotting Precedent Issues

Look for:

  • Question asks "Is court bound?"
  • Multiple similar cases cited
  • Request to "advise" based on earlier cases
  • "Apply the law" to new facts

IRAC Framework

Issue: Is the court bound by [case name]?

Rule:

  • State doctrine of precedent
  • Cite court hierarchy
  • Explain ratio vs obiter

Application:

  • Identify which court issued precedent
  • Identify which court is deciding current case
  • Is precedent binding or persuasive?
  • If binding, is ratio or obiter?
  • Can it be distinguished?

Conclusion:

  • Court bound/not bound
  • Must follow / may follow / free to depart

Sample Answer

Question: "The Constitutional Court held that life imprisonment without parole violates Section 10 (dignity). Must a High Court follow this?"

Answer:

"YES, the High Court must follow.

Rule: Under the doctrine of stare decisis, lower courts are bound by the ratio decidendi of higher courts (vertical precedent).

Application: The Constitutional Court is the highest court on constitutional matters. All lower courts—including High Courts—are bound by Constitutional Court decisions on constitutional interpretation.

The statement that 'life imprisonment without parole violates Section 10' is ratio decidendi (not obiter) because it is the legal principle necessary to decide the case.

Conclusion: The High Court must follow this precedent. It cannot impose life without parole in any case unless the Constitutional Court overrules its own decision or the Constitution is amended."

⚠️ Common Mistakes

❌ Confusing ratio and obiter

  • Only ratio is binding
  • Obiter is persuasive

❌ Thinking same-level courts bind each other

  • Horizontal precedent is persuasive, not binding

❌ Forgetting courts can distinguish

  • Even binding precedent doesn't apply if facts materially different

❌ Assuming foreign cases bind SA courts

  • Foreign precedent is persuasive only (Section 39(1)(c) says "may consider")

✅ Remember: Stare decisis promotes consistency, but flexibility allows law to develop.

🎓 Summary

Stare decisis:

  • Courts follow previous decisions
  • Promotes certainty, consistency, fairness

Binding precedent:

  • Higher courts bind lower courts (vertical)
  • Only ratio decidendi binds
  • Lower court must follow

Persuasive precedent:

  • Same-level courts
  • Foreign cases
  • Academic writing
  • Obiter dicta
  • Court may follow but not obliged

Departing from precedent:

  • Constitutional Court can overrule own decisions
  • SCA can depart (rare)
  • High Courts can depart from own decisions

Distinguishing:

  • Show material factual/legal difference
  • Precedent doesn't apply
  • Precedent remains good law
