To read a Supreme Court judgment properly, break it into four layers: the material facts the court accepted, the questions of law those facts raised, the reasoning the court needed to answer them (the ratio decidendi), and everything else said along the way (obiter dicta). Only the ratio carries binding force under Article 141 of the Constitution, so the real work lies in isolating the reasoning the result could not do without. This guide walks through each layer on real judgments, Maneka Gandhi v Union of India (1978) and Virsa Singh v State of Punjab (1958), so you can repeat the method on any case in your syllabus.
What are the parts of a reported Supreme Court judgment?
A reported judgment is the court's own text wrapped in an editorial shell, and the first skill is knowing which parts the judges actually wrote. Open the official copy of Maneka Gandhi on the Supreme Court website and you will see the familiar layout of older reports: petitioner and respondent, date of judgment (25 January 1978), the bench of seven (Beg CJ, Chandrachud, Bhagwati, Krishna Iyer, Untwalia, Fazal Ali and Kailasam JJ), the citations 1978 AIR 597 and 1978 SCR (2) 621, then the Act, the headnote and finally the judgment itself.
| Part | Who writes it | What you should take from it |
|---|---|---|
| Cause title, date, bench, citation | Registry or reporter | Bench strength, which decides how far the case binds later benches |
| Headnote | Reporter or editor | A map for finding the case, never a quotation for your answer |
| Arguments of counsel (where reported) | Reporter's summary | The competing positions, useful for understanding the issues |
| Opinions of the judges | The judges | Facts found, issues, reasoning, conclusion |
| Operative order | The court | What was actually ordered: allowed, dismissed, remanded |
The headnote deserves a warning. It is a summary written by someone other than the court, and it often compresses a qualified statement into a flat rule. Read it to find your way, then go to the paragraphs it points to.
Which facts in a judgment are material and which are background?
Material facts are the facts the court treated as decisive for its conclusion; everything else is narrative. In Maneka Gandhi, the passport was impounded by an order of 2 July 1977 under section 10(3)(c) of the Passports Act, 1967 "in public interest", the Government declined "in the interest of the general public" to give her a copy of the statement of reasons, and no hearing was given before the order. Those three facts drive every opinion in the case. The identity of the petitioner and the political background, however much space they take in commentary, are not what the reasoning turns on.
A practical test is to write the facts in under sixty words. If you cannot, you are still carrying background. Suppose a later petitioner's passport is impounded with reasons supplied and a post-decisional hearing offered within a week. Your sixty-word summary of Maneka should let you see at once which fact has changed and whether it matters.
How do you frame the issues the court actually decided?
An issue is a question of law, raised by the material facts, that the court had to answer to dispose of the case. Many judgments list the questions; when they do not, you must reconstruct them. In Maneka the questions were whether the right to go abroad falls within "personal liberty" in Article 21, whether Articles 14, 19 and 21 operate in separate compartments, and whether section 10(3)(c) was void for excluding a hearing.
Frame each issue as a yes or no question tied to a specific provision. "Was natural justice violated?" is too loose. "Does section 10(3)(c) of the Passports Act exclude the audi alteram partem rule, and if so is it void under Article 21?" is an issue you can answer and an examiner can mark.
How do you find the ratio decidendi of a judgment?
The ratio decidendi is the principle of law that was necessary for the decision on the material facts. The Supreme Court has warned against looking for it in a single paragraph. In Islamic Academy of Education v State of Karnataka (2003), dealing with T M A Pai Foundation, the Court said the ratio "has to be found out only on reading the entire Judgment" and that the answers printed at the end of Pai were "merely a brief summation" of it.
Use these steps on any judgment:
- Note the conclusion in the operative part: what was allowed, set aside or upheld.
- List the reasons the judges give for that conclusion, in their own words.
- Remove each reason in turn and ask whether the conclusion would survive. This is the inversion test associated with Eugene Wambaugh. A reason whose removal would change the result is part of the ratio.
- State the surviving reason as a rule that connects the material facts to the result.
- Check whether later benches have read the case the same way, followed it, explained it or overruled it.
Virsa Singh is the cleanest illustration. The accused thrust a spear into the deceased's abdomen and the injury was sufficient in the ordinary course of nature to cause death; the Sessions Judge found he intended only grievous hurt. Bose J held that for murder under the third clause of section 300 IPC, now section 101(c) of the Bharatiya Nyaya Sanhita, the prosecution must prove four things: that a bodily injury is present, the nature of that injury, that the accused intended to inflict that particular injury (not an accidental one or a different kind), and that the injury so described is sufficient in the ordinary course of nature to cause death. Once those are proved, it does not matter that there was no intention to cause death. That four-part test is the ratio. The vivid description of the coils of intestine protruding from the wound is part of the facts, not the law.
What counts as obiter dicta, and who decides?
Obiter dicta are statements of law that were not necessary for the decision, and very often it is a later bench that decides which category a statement falls into. Maneka Gandhi itself shows this happening. A K Gopalan v State of Madras (1950) had been read for years as holding that Articles 19 and 21 operate in separate fields. In Maneka, Beg CJ said that the real ratio of Gopalan was narrower: that Article 22 was a self-contained code for laws of preventive detention, and that the other observations on the separability of Articles 19 and 21 "were mere obiter dicta".
Two lessons follow for revision. First, when you note a landmark case, also note how later benches have characterised it, because the reading that binds today may not be the one the original reporters gave it. Second, do not dismiss obiter as worthless. A deliberate observation of the Supreme Court is usually followed by High Courts and trial courts even where it was not strictly needed, while a passing remark carries little weight. In an answer, say which it is.
How much of a judgment binds which court?
Article 141 makes the law declared by the Supreme Court binding on all courts within India, but it does not bind the Supreme Court itself. In Bengal Immunity Co Ltd v State of Bihar (1955) a seven-judge bench held that Article 141 refers to courts other than the Supreme Court and that the Court may depart from its own earlier decision when convinced it is wrong, while exercising that power with care. Within the Supreme Court, bench strength governs.
| Situation | Effect |
|---|---|
| Ratio of a Supreme Court decision | Binds every High Court and subordinate court under Article 141 |
| Earlier decision of a bench of equal or larger strength | Binds a later bench; a doubting bench should refer the question to a larger bench (Union of India v Raghubir Singh, 1989) |
| Question of law on the interpretation of the Constitution | Needs a bench of at least five judges under Article 145(3) |
| Majority opinion across several judgments | Find the common ground that commands a majority on each point |
| Dissent | Binds no one, but may be adopted later by a larger bench |
| Decision per incuriam | Loses binding force on the point decided in ignorance of a binding statute or precedent |
Multiple opinions need patience. In Kesavananda Bharati v State of Kerala (1973) thirteen judges wrote eleven opinions, and the basic structure limitation on the amending power rests on the view of seven of them. When you revise such a case, record the vote on each question rather than a single "held". Dissents also matter for the long run. Justice H R Khanna's dissent in ADM Jabalpur (1976) was vindicated when the nine-judge bench in Justice K S Puttaswamy v Union of India (2017) overruled the majority view. The LegalFirms magazine piece on a recent split decision in the Supreme Court is a good exercise in reading two opinions on the same question side by side.
Status matters too. Islamic Academy, quoted above for its statement on ratio, was itself overruled in part by P A Inamdar v State of Maharashtra (2005), which said that part of Islamic Academy did not lay down the correct law. A note that says only "Islamic Academy: fee committees" without that warning will mislead you in an exam.
How are judgments tested in judiciary exams?
Prelims test judgments through precise recall: the year, the provision, the holding, sometimes the bench strength or the case that was overruled. Mains test application: a fact pattern is given and you must apply a ratio to it, which you can only do if you extracted the ratio and not the story. Viva boards often ask why a case matters, which is a question about its ratio and its later treatment.
Here is how the method pays off. Suppose a question says: A, in a quarrel, strikes B once on the head with a heavy iron rod; medical evidence shows a skull fracture sufficient in the ordinary course of nature to cause death; A says he only meant to teach B a lesson. A candidate who remembers Virsa Singh as "spear case, murder" has little to say. A candidate who remembers the four-part test walks through each element: injury present, nature proved, intention to inflict that particular injury on the head inferred from the weapon and the part of the body struck, sufficiency proved by medical evidence, and concludes that the absence of an intention to kill does not take the case out of section 101(c), subject to any exception being made out on the facts.
Common mistakes that cost marks:
- quoting the headnote as though it were the court's words;
- describing the facts at length and stating the holding in one vague line;
- citing a case for a proposition that a later bench has overruled or confined;
- treating every sentence of a long judgment as law, including obiter on questions not before the court;
- giving the year of the report instead of the year of decision without saying so.
A short brief for each case keeps you out of these traps. Write it in five lines: citation and bench, material facts, issue, ratio in one sentence, and current status. Test yourself on the landmark judgments mock papers and build targeted sets from the cases you keep confusing in Practice.
Key points to remember
- Separate four layers: material facts, issues, ratio decidendi and obiter dicta.
- The headnote is the reporter's summary, not the court's text.
- Find the ratio by reading the whole judgment and applying the inversion test to each reason.
- Later benches often decide what an earlier ratio was, as Maneka Gandhi did with Gopalan.
- Article 141 binds all courts other than the Supreme Court; within the Court, equal or larger benches bind smaller ones.
- Record the vote on each question in multi-judge cases, and record dissents that were later adopted.
- Always note whether a case has been followed, confined or overruled before you cite it.
Where to go next
Start with the full case pages in Landmark Judgments, each laid out as facts, issues and holding, and test your briefs against the pages for Maneka Gandhi, Virsa Singh and Union of India v Raghubir Singh. For a sustainable routine, read the companion guide on building a case-law reading habit. When you want fresh material that no guidebook has summarised yet, practise the five-line brief on recent decisions from the LegalFirms index of Supreme Court and High Court judgments.
