Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

The examinable core. Every question on the judicial process asks the same thing in different words: is the judge a finder of law or a maker of it, and if a maker, what limits the choice? Cardozo’s answer — the judge makes law, but only in the gaps, and by methods that can be named — is the frame for this whole paper.

A note on the syllabus. These notes follow the KSLU LL.M. syllabus (2019–20) for this paper and the past papers.

1. What “judicial process” means

The judicial process is the method by which a court moves from a dispute to a binding decision: finding the facts, identifying the legal materials, choosing among competing rules or meanings, and justifying the result in reasons. The older account, associated with Blackstone, treats the judge as an oracle who declares a law that already exists. The modern account, which begins with Holmes and Cardozo and runs through the American realists, Hart and Dworkin, accepts that in a real number of cases the materials do not dictate one answer and the judge must choose.

Holmes put the shift in The Common Law (1881): “The life of the law has not been logic: it has been experience.” Lord Reid, in his 1972 lecture The Judge as Law Maker, called the belief that judges never make law a fairy tale that nobody any longer accepts. The live debate today is about the limits of judicial choice, not its existence.

2. Cardozo, The Nature of the Judicial Process (1921)

Benjamin N. Cardozo, then a judge of the New York Court of Appeals and later of the United States Supreme Court, delivered the Storrs Lectures at Yale in 1921 and published them as The Nature of the Judicial Process. He set out to describe honestly how he decided cases. His account has four parts.

The four methods

  1. The method of philosophy (logic, analogy). The judge extends a principle found in earlier decisions to the new case. This is the default, because consistency and predictability are values in themselves.
  2. The method of evolution (history). Some rules can only be understood through their origin — land law and its feudal past are his example — and history fixes the direction in which logic should be pushed.
  3. The method of tradition (custom). The customs and practices of the community, including commercial practice, supply content and test whether a rule still fits.
  4. The method of sociology (social welfare). Where the other methods run out or point different ways, the judge asks which result serves justice, morals and social welfare. Cardozo wrote that the final cause of law is the welfare of society.

The judge as interstitial legislator

Cardozo accepted that judges legislate, but only in the gaps the law leaves open. Most cases, he said, are decided one way and could not reasonably be decided another; a smaller number are the cases where the decision makes law. Holmes had made the same point in Southern Pacific Co. v. Jensen (US Supreme Court, 1917): judges legislate only interstitially, confined from molar to molecular motions. Even where the judge is free, he is not wholly free — he draws on the community’s standards, not his private preferences, and must give reasons that others can test.

The subconscious forces

Cardozo’s most candid passages concede that a judge’s inherited instincts, training and outlook shape his choices below the level of conscious reasoning. He did not think this made adjudication arbitrary; he thought the discipline of precedent, reasons and professional tradition kept it in check. The realists (Jerome Frank, Law and the Modern Mind, 1930) went further and treated the stated reasons as rationalisation of a result reached on other grounds.

The usual criticism, and the answer. Critics say Cardozo gives the judge no rule for choosing between the four methods. The answer is that he did not claim to: he said the method of sociology is the arbiter when the others conflict, and that the choice is itself a judgment of value. That candour is what makes the book the starting point for Dworkin, who argued that principles, not social policy, should do that work.

3. The common law model

The common law model of adjudication, which India inherited, has these features.

The civil law model differs at each point: a comprehensive code is the primary source; judicial decisions are applications of the code and, formally, bind only the parties (though a settled line of decisions, jurisprudence constante, carries great weight); procedure is more inquisitorial; and judgments are often short and unsigned, as in the French Cour de cassation. The two models have converged. Common law systems now legislate heavily, and civil law apex courts (and the Court of Justice of the European Union) build up case law that functions as precedent.

4. What fairness requires of the process

Whatever one thinks about law-making, the process must satisfy certain conditions to command acceptance. These are the “fundamental principles and procedures” an internal paper asked about.

Lon Fuller’s account of adjudication (“The Forms and Limits of Adjudication”) adds that adjudication is suited to disputes that can be framed as claims of right, and less suited to “polycentric” problems with many interacting parties. That is exactly the objection later raised against public interest litigation in India.

5. The judicial process in constitutional adjudication

Constitutional cases differ from ordinary ones in ways that enlarge the judge’s choice.

The contrast with ordinary statutory work is one of degree. A judge construing a tax statute also chooses, but within narrower bounds and under a legislature that can reverse him by ordinary majority. That is why constitutional adjudication is where the debates on activism and restraint concentrate (see the note on judicial activism).

How this is examined

Expect “Examine Cardozo’s view of the nature of the judicial process” or “What principles characterise the judicial process?” (July 2024 internal) and a short note on the common law model (August 2024, Q.7(a)). For the Cardozo essay, give the four methods, the interstitial point with Holmes, and the subconscious forces, then set him against the declaratory theory and the realists. For constitutional adjudication, structure the answer around open text, the counter-majoritarian difficulty and structural reasoning, with Kesavananda as the leading illustration.
