The case method of teaching law

1. Origin: Langdell at Harvard

Christopher Columbus Langdell became dean of the Harvard Law School in 1870 and in 1871 published a casebook on the law of contracts. He replaced the lecture and textbook with the study of selected appellate decisions. His premise, stated in the preface to the casebook, was that law, considered as a science, consists of a small number of principles and doctrines, that these have developed through a long series of cases, and that the best way to master them is to study the cases in which they were developed. The library was the lawyer’s laboratory and the cases its specimens.

The method spread to almost every American law school by the early twentieth century and, with the Socratic method of questioning that came with it, became the defining feature of American legal education.

2. How the method works

1. The teacher selects leading cases on a topic and arranges them in a casebook in an order that shows the development of a principle.
2. Students read the cases before class and prepare a “brief” of each: facts, issue, decision, reasoning, ratio, and any dissent.
3. In class the teacher calls on students to state the case and then questions them on the reasoning, varies the facts to test the principle, and compares it with other cases.
4. Students build the principle themselves from the cases, rather than receiving it from a lecture.
5. The examination usually sets a hypothetical problem requiring application of the principles learnt.

3. Merits

• Active learning: students work out principles for themselves, so they understand and remember them.
• Training in legal reasoning: reading judgments, separating ratio from obiter, distinguishing cases, and arguing by analogy are the core skills of the common-law lawyer.
• Primary sources: students learn from the law itself, not from someone’s summary of it.
• Law as growth: the student sees how a doctrine develops and changes with circumstances, which a statement of rules hides.
• Facts: cases show law operating on real disputes.
• Preparation for practice: the advocate’s daily task is to find, read and use cases.

4. Criticism

The realists. Jerome Frank (in his 1933 article asking why there was no clinical lawyer-school) argued that appellate cases are a poor diet: they present facts already found and ignore the trial, where most of the lawyer’s work and most of the injustice lie. Langdell’s claim that law is a science was formalism: it treated law as a closed logical system and ignored policy and social effects.

Educational criticism.

• It is slow; coverage of a syllabus suffers.
• It needs small classes, well-prepared students, a good library and skilled teachers.
• It neglects statutes, which now dominate law.
• It neglects skills other than analysis — drafting, negotiating, counselling, fact investigation — and neglects values.
• Beginners without a conceptual framework may find it confusing.

The Carnegie Foundation’s Educating Lawyers (2007) acknowledged the power of the case-dialogue method to teach legal analysis but found that it left the practical and ethical sides of lawyering under-developed.

5. Suitability to India

The modified forms are:

• Cases and materials: casebooks that combine judgments with statutory provisions, Law Commission reports, articles and social data. The Indian Law Institute published such materials in the 1960s and 1970s for several subjects.
• Leading-case teaching within lectures: the teacher lectures on the structure and assigns a few leading cases for close reading and discussion.
• Case analysis assignments: written case comments, which also train research and writing.

Indian law has also given the method rich material. Constitutional law can hardly be taught without Kesavananda Bharati (1973), Maneka Gandhi (1978) and Puttaswamy (2017), read in full, because the doctrine lives in the reasoning. The Supreme Court’s own practice of long judgments with several concurring opinions makes the task harder: students must learn to find the majority view and the binding ratio among them, a skill the case method trains directly.

6. A case-method class in outline

Take Donoghue v. Stevenson (House of Lords, 1932) in a torts class. Students read the speeches before class. The teacher asks one student for the facts and the issue: does a manufacturer owe a duty of care to the ultimate consumer with whom he has no contract? A second student states Lord Atkin’s neighbour principle. The teacher then varies the facts: what if the bottle had been clear and the snail visible? What if the drink had been bought for resale by a shopkeeper who could inspect it? What if the harm had been only financial loss? Each variation tests the limits of the principle and leads to later cases (Hedley Byrne on negligent statements, Caparo on the three-stage test). The class ends with students stating, in their own words, the rule and its boundaries. Nothing has been lectured; everything has been worked out from the case.

7. Case method and lecture compared

8. Case method and the lawyer’s skills

The case method teaches the student to read authority, the skill that the doctrinal researcher also needs. The note on doctrinal legal research sets out the same operations as research steps. The problem method, treated next, extends the case method from reading decided cases to solving undecided ones.

How this is examined

As a short note or an essay: Langdell and his premise, the working in five steps, six merits, the realist and educational criticism, and suitability to India with the cases-and-materials adaptation. A comparison with the lecture method in a few lines is a good close.
