The Bench of Thirteen Was a Procedural Choice, Not a Constitutional Necessity

Here is a small constitutional puzzle. The largest bench in Indian Supreme Court history sat in Kesavananda Bharati¹ from October 1972 to March 1973 — thirteen judges, sixty-eight working days, 488,325 words of opinions. The judgment is the foundation of the basic-structure doctrine and, fifty-three years on, of nearly everything we say about judicial review in India. Ask any third-year law student where the number thirteen comes from and the answer comes back fluent: it had to be thirteen because the earlier Golak Nath² bench had been eleven and you need a strictly larger bench to overrule.

That answer is doctrinally familiar and constitutionally false. Article 145(3) of the Constitution³ requires only five judges for cases involving 'a substantial question of law as to the interpretation of this Constitution.' Five is the floor. Anything above five is a choice. There is no rule in the Constitution, no rule in the Supreme Court Rules, and no rule even in the Court's own bench-size precedents⁴ that required Kesavananda to sit thirteen. The number was Sikri CJ's procedural choice, exercised under his listing power as Chief Justice — one more than the eleven of Golak Nath, ostensibly so that Golak Nath could be reconsidered, but more candidly so that the Court could deliver a final word on Article 368 that no one could later second-guess on bench-size grounds. The View of the Majority and Final Order in Kesavananda was, in the end, signed by only nine of the thirteen judges⁸; Ray J refused to sign it. The thirteen-judge bench produced, in operative terms, a nine-judge signed agreement and a 7-6 holding on the central question. Thirteen was the size of the room, not the size of the consensus.

I want to take that small puzzle seriously, because I think it explains rather a lot about how Indian constitutional law has actually been made. The bench-size of every major basic-structure case from Kesavananda through Indira Nehru Gandhi to I.R. Coelho⁹ and the NJAC case⁵ has been a political decision the Court makes about itself. Once we see that, we are forced to ask what it means to call the size of the bench a part of the doctrine — and what it means when the bench size and the doctrine come apart.

What Article 145(3) actually says

Read the text. Article 145(3) reads: 'The minimum number of Judges who are to sit for the purpose of deciding any case involving a substantial question of law as to the interpretation of this Constitution or for the purpose of hearing any reference under Article 143 shall be five.' Five. That is the entire constitutional rule on bench size.

The framers did not say a basic-structure question must be heard by thirteen. They could not have said so — the basic-structure doctrine did not yet exist. What they did was set a floor and trust the Court with everything above the floor. The Supreme Court Rules under Article 145 elaborate procedural details (the Chief Justice's listing power, the form of the order paper, the conduct of references) but nowhere fix a higher number. Constitution-bench practice — sevens, nines, elevens, thirteens — is entirely the product of the Chief Justice's discretionary administration of the docket¹⁰.

So why does Indian constitutional law treat bench size as if it were doctrine? The answer is in Central Board of Dawoodi Bohra Community v State of Maharashtra⁴, decided by a five-judge bench in 2005. The Court there laid down what is now the canonical rule: 'The law laid down by this Court in a decision delivered by a Bench of larger strength is binding on any subsequent Bench of lesser or co-equal strength.' To overrule a bench of N judges, you need at least N+1. The rule is a sensible rule of internal coherence. It is also a rule the Court made for itself. It is nowhere in the Constitution.

The rule has a corollary the Court is less keen to advertise. Once Kesavananda sat thirteen, any future Court that wanted to depart from Kesavananda would need at least fourteen. Since the Court at full sanctioned strength was, in 1973, only fourteen and a fraction (the strength has fluctuated; today it is thirty-four), reconsidering Kesavananda became, as a practical matter, impossible without convening the entire Court — and even then, by Robinson's calculation, the modern reckoning requires a bench of fifteen to reconsider in full⁷.

That is the achievement Sikri CJ secured. The basic-structure doctrine was made unreviewable not by the strength of the reasoning that supports it — the seven-judge majority was thin, the dissents were not weak — but by the procedural moat the Chief Justice dug around it before the judgment was even delivered. We have lived inside that moat for fifty years and we mostly do not notice it is there.

The procedural history is the story we do not tell

The bench-size escalation in the Article 368 cases is its own narrative arc, and once you trace it the constitutional-necessity story collapses.

Sankari Prasad in 1951 — five judges. Sajjan Singh in 1965 — five judges. Golak Nath in 1967 — eleven judges, deliberately constituted by Subba Rao CJ to allow the Court to depart from Sankari Prasad. Kesavananda in 1972-73 — thirteen judges, deliberately constituted by Sikri CJ to allow the Court to depart from Golak Nath. Each step up was the work of a particular Chief Justice exercising the administrative power to constitute the bench. Each step up was made under the same Article 145(3) that requires only five.

The Kesavananda Counsel and Proceedings record⁶ is itself revealing. Palkhivala for the petitioners; Niren De as Attorney-General for the Union; H. M. Seervai as Advocate-General for Maharashtra; the writ petition was W.P. No. 135 of 1970. Sixty-eight working days of hearing. Five months of judgment-writing. Eleven opinions in the final report. Every one of the procedural-administrative levers — when to constitute the bench, who to put on it, when to close arguments, when to deliver — sat in Sikri CJ's hands. The substantive opinions of the thirteen judges are public; the procedural calculation that put thirteen of them in the same Court Room 1 on Tilak Marg is, by the nature of Indian judicial administration, not.

This is not a complaint. Every common-law judicial system gives its Chief Justice administrative authority over benches; the alternative — a random or rotating system — has its own costs. What I am noticing is narrower: we have been talking about Kesavananda as if its bench-size was a constitutional necessity, when it was nothing of the kind. The number thirteen was an act of judicial administration. It deserves the respect we give to administrative acts. It does not deserve the deference we give to text.

It is worth lingering on the comparative point. The United States Supreme Court hears every constitutional case en banc — all nine justices, every time. The bench is fixed by statute and the Court's procedural choices do not include 'how many of us hear this.' The United Kingdom's Supreme Court, since 2009, sits ordinarily in panels of five and occasionally seven or nine, but the panel constitution is governed by published rules of the Court rather than by Chief-Justice discretion. The Court of Justice of the European Union sits in chambers of three, five or fifteen with the size determined by the procedural code of the Statute of the Court. Indian practice is the outlier: a constitutional floor of five and effectively unlimited administrative ceiling, with the ceiling chosen case by case by the Chief Justice. That structure is not constitutionally required. It is what the Court has settled into. And what the Court has settled into is what gives the Chief Justice's bench-listing power its constitutional weight.

What the bench size does for the doctrine — and against it

Treating the bench-of-thirteen as if it were a constitutional fact has three concrete effects on how basic-structure doctrine operates in Indian constitutional law, and all three are worth examining honestly.

The first effect is entrenchment. As noted, Kesavananda can now only be reconsidered by a larger bench — and the practical and political costs of convening such a bench are prohibitive. This entrenchment is not all loss. There is genuine constitutional value in a doctrine that protects fundamental architecture from each new Court's preferences. But the value of the entrenchment is borrowed from the bench-size rule, not from the doctrine's own internal strength. If we were forced to defend Kesavananda on the merits before a fresh bench of five — the constitutional minimum — we would have to write better defences than the ones we have settled for.

The second effect is selective overruling without admitting it. Robinson notes that a smaller bench can 'carefully reinterpret parts of Kesavananda Bharati while claiming to be in compliance with the judgment'⁷. This has happened, repeatedly, since 1973. The Court has expanded and contracted what counts as basic structure without ever convening fifteen judges. Minerva Mills, Waman Rao, S.R. Bommai, L. Chandra Kumar, I.R. Coelho⁹ — each of these is, in substance, an addition to the list of basic-structure elements. None was decided by a bench of fourteen. The procedural rule that purports to entrench Kesavananda has, in practice, allowed quiet revisions without the political accountability that a larger bench would require.

The third effect is the one this essay is most concerned with: it has authorised the Court to read its own bench-size choices as constitutional acts. If thirteen judges chose to recognise the basic-structure doctrine, then five judges can choose to identify additional basic-structure elements — and the additional elements get the doctrinal weight of Kesavananda attached to them by association. This is the substantive cost of the procedural fetish. It allows a bench of five to legislate constitutional architecture while claiming to merely apply the architecture that thirteen judges installed. The legitimacy laundering runs in only one direction.

The NJAC bench was five. The objection that should have been raised was not.

This brings me to Supreme Court Advocates-on-Record Association v Union of India⁵ — the NJAC case — decided in October 2015 by a five-judge bench, striking down the 99th Constitutional Amendment and the National Judicial Appointments Commission Act 2014 by 4-1 as violations of the basic structure.

The substantive case has been argued at length and there is no need to rehearse it. I want to focus narrowly on the bench-size question. The NJAC bench was constituted at the constitutional minimum — five — for the largest structural change to Indian judicial appointments since 1993. The 99th Amendment had been passed by both Houses of Parliament unanimously, ratified by sixteen State Legislatures, and given the Presidential assent. It was, on any measure, the most strongly democratically backed constitutional amendment of the last twenty years. And the Court that struck it down was constituted at the same number that would have heard a routine Article 14 reasonableness review.

Compare the bench arithmetic on either side of the case. The Court in Kesavananda spent thirteen judges and sixty-eight working days to install a doctrine that limits Parliament's amending power. The Court in NJAC spent five judges and a markedly briefer hearing to use that doctrine to strike down the most heavily ratified constitutional amendment of the post-Emergency era. The Court of 1972 thought a thirteen-judge bench was necessary because it was about to do something significant. The Court of 2015 thought a five-judge bench was sufficient to do something more significant — re-entrench judicial appointment power against an amendment passed by Parliament and ratified by half the States — because of the very doctrine the Court of 1972 had installed.

I do not think the NJAC majority was wrong about the centrality of judicial independence to the basic structure. I think they were wrong about the bench. If the NJAC question — whether the structure of judicial appointments is itself part of the basic structure — was important enough to overturn a fully ratified Constitutional Amendment, then it was important enough to be heard by a bench that signalled the gravity of the constitutional moment. Five judges, in this context, was an institutional understatement. The Court should have constituted at least eleven — the same number that decided Golak Nath — and arguably thirteen, the same number that decided Kesavananda itself. Doing the smaller thing on the smaller bench let the Court treat as routine a question that was not routine.

The bench-size choice was not an oversight. It was deliberate. The Chief Justice of the day exercised the administrative discretion he had under the Rules and chose five. That is a choice that deserves to be examined. Why five and not eleven? The honest answer, I suspect, is that a larger bench would have made it harder for the Court to deliver its preferred result. The wider the bench, the more diverse the views; the more diverse the views, the harder to muster a clear basic-structure majority. The Chief Justice picked the bench that would let the Court do what the Court wanted to do.

If the procedural choice of bench size is, as I have argued, a political instrument the Court hands itself, then NJAC is what happens when the Court uses that instrument in its own institutional interest. The Court was choosing the bench size for a case about its own appointment power. The conflict of interest is structural. We do not normally let interested parties pick the size of the tribunal that hears their case. The Supreme Court did, in NJAC, exactly that.

Consider the asymmetry from the other direction. Imagine an alternative-history NJAC bench of thirteen. The composition of such a bench would have included at least some judges who had publicly defended elements of the collegium and at least some who had publicly criticised it. The deliberations would have surfaced the strongest version of each side of the question. The judgment would have carried the moral weight of a Court visibly grappling with its own institutional interest in front of the country. The 4-1 majority that we actually got — Khehar J, with Lokur, Goel and Kurian Joseph JJ; Chelameswar J in solitary dissent — was not an ungenuine deliberation, but it was a small one. Chelameswar J's dissent reads now as a structural objection that the larger bench would have been forced to take more seriously. The five-judge constitution of the case did not produce a wrong outcome by accident. It produced a narrower argument than the question deserved.

There is a further wrinkle worth raising. The bench-of-five chose to characterise the appointment of judges as itself part of the basic structure of the Constitution. Kesavananda identified the independence of the judiciary as basic structure; it did not, in 1973, identify the specific mechanism of appointment as such. The collegium itself was a 1993 innovation of the Second Judges Case and a 1998 reformulation in the Third Judges Case, both also five-judge benches in their substantive constitutional law. So the structural fact the NJAC bench identified as part of the basic structure was a fact the same Court had created barely twenty years earlier — on benches of the same size — and was now placing beyond Parliament's reach. The bench-size question is impossible to disentangle from the question of who got to define basic structure in the first place. Five judges of one decade installed the collegium; five judges of another decade entrenched it as basic structure. There is no thirteen-judge ratification anywhere in this chain.

What an honest view of bench size would change

I want to be careful here. I am not arguing that the basic-structure doctrine should be abolished. I am not arguing that the NJAC outcome was wrong on substance. I am not arguing that the Chief Justice's listing power should be stripped. Each of those would be a separate argument and each is harder to make than this one.

I am arguing for a smaller and more achievable thing: that we should stop pretending the size of a constitution bench is part of the doctrine the bench produces, and start treating it as what it is — an administrative act by the Chief Justice, contestable on administrative grounds, defensible on administrative grounds, and answerable to administrative review. Three concrete consequences follow.

First, the rule from Dawoodi Bohra Community — that a bench of N can only be overruled by a bench of N+1 — should be acknowledged as a judicially-made internal coherence rule, not as a constitutional one. It can be revised. It can be tightened. It can, where appropriate, be relaxed in cases where the smaller bench is being asked not to overrule but to interpret. The Court's reluctance to convene fifteen-judge benches to revisit Kesavananda is intelligible — fifteen judges is most of the Court — but it should be the Court's choice to acknowledge openly, not an iron rule it pretends is binding.

Second, the Chief Justice's bench-listing power in cases of constitutional gravity should be subject to a published rationale. When the Court constitutes a bench of five for a case like NJAC, it should record why five and not eleven. When it constitutes a bench of seven for an Article 21 reference, it should record why seven and not nine. The reasoning need not be elaborate. But the publicity of the choice would discipline the choice. At present, the only public document about a bench-size decision is the constituted bench itself.

Third, scholars and litigators should stop using bench size as if it were a measure of constitutional weight. We routinely write that 'the nine-judge bench in Puttaswamy held' or 'the seven-judge bench in Maneka held' as if the number were doing some of the doctrinal work. It is not. The doctrinal work is done by the reasoning of the judges. The number is a procedural fact. Using it as a substantive proxy is a habit we have picked up from the Court's own self-presentation and we should drop it.

None of these is a programme for reform. They are corrections to how we think about a small but consequential feature of Indian constitutional practice. The smallness is the point. We have built five decades of constitutional law on a number Sikri CJ chose in 1972 — a number that was, even at the time, a procedural answer to a procedural question. The number has done useful work. It has also done unacknowledged work. The doctrine is more defensible when we are honest about which of those is which.

What the smaller bench actually decided

One last point on NJAC, which closes the case for treating bench size as the issue. The smaller bench was not, in fact, smaller because the case was less important. The NJAC case raised exactly the kinds of questions that the framers of Article 145(3) had in mind when they set the floor at five — a substantial question of law as to the interpretation of the Constitution, going to the structure of one of the three branches of government. It also raised questions Kesavananda itself had left open. Kesavananda identified judicial review as part of the basic structure but did not explicitly include the appointment process. The NJAC bench made that move — extending basic structure to include the collegium-style judicial appointment process — for the first time.

That move is a doctrinal expansion of Kesavananda. And under the Dawoodi Bohra rule, a doctrinal expansion of a thirteen-judge decision should require a bench of at least fourteen. The fact that it was made by five tells us that either the rule is not as binding as the Court says it is, or that the Court is willing to expand basic-structure architecture without the institutional gravity that Kesavananda itself thought necessary. Both are problems. Both are problems we are not currently talking about, because we are still treating thirteen as if it were the constitutionally compelled answer rather than the procedural answer it was.

The thirteen of Kesavananda was a procedural choice, not a constitutional necessity. Once we say that out loud, we have to ask what we owe the procedural choices that came after. Five for NJAC was also a procedural choice. So is every constitution-bench number that follows. The Court has been making those choices in plain sight for fifty years. We have been treating them as facts of nature.
