How do I critically analyse case law in my essays?

Critical analysis means evaluating the reasoning, identifying weaknesses, comparing with other authorities, and considering whether the decision achieves justice or coherence in the law.

student 2 min read

Simply describing what a court decided is not critical analysis — it is narration. To achieve higher marks, you must evaluate the court's reasoning, compare it with other authorities, and assess whether the decision is principled.

Step 1: Identify the Ratio Decidendi

Before you can analyse a case, you must accurately identify the ratio decidendi — the legal principle that the case establishes. Distinguish this from obiter dicta (remarks made in passing).

Step 2: Evaluate the Reasoning

Ask yourself: Is the court's reasoning logically consistent? Does the decision follow from the precedent cited? Are there any policy considerations driving the decision that the court does not explicitly acknowledge?

Step 3: Compare with Other Authorities

Situate the case within the broader legal landscape. How does it relate to earlier decisions? Has it been distinguished, applied, or overruled? Do academic commentators agree with the court's approach?

Step 4: Consider Dissenting Judgments

Dissenting judgments are gold dust for critical analysis. They provide a ready-made counter-argument that you can engage with.

Step 5: Assess the Broader Impact

Consider whether the decision promotes certainty, fairness, or efficiency in the law. Does it align with Law Commission recommendations?

Useful Phrases for Critical Analysis

  • "While the court's reasoning in X is internally coherent, it fails to account for..."
  • "Professor Smith persuasively argues that the ratio in X is too narrow because..."
  • "The dissent in X raises a compelling objection, namely that..."
  • "This decision creates an uncomfortable tension with the earlier ruling in Y..."

Key Takeaway

Critical analysis means evaluating the reasoning, identifying weaknesses, comparing with other authorities, and considering whether the decision achieves justice or coherence in the law.
