The Basic Structure Doctrine: A simpler way of understanding

Imagine you inherit a house. The will says you can renovate it however you like. New paint, new rooms, even a new roof. But you cannot knock down the foundation. Because without the foundation, there is no house left to renovate. That, in a nutshell, is the Basic Structure Doctrine.

It is one of the strangest and boldest ideas in constitutional law. Parliament can amend the constitution. That power is real. But some parts of the constitution, courts say, are so fundamental that even Parliament cannot erase them. Not through a simple majority. Not even through a supermajority. Some things are just off-limits!

The Quarrel That Came First

The doctrine did not arrive out of nowhere. It arrived after two decades of arguing.

In the 1950s and early 1960s, the Indian Supreme Court twice held that Parliament's power to amend was broad enough to touch even fundamental rights. Then, in 1967, it changed its mind and said the opposite: fundamental rights were beyond the reach of amendment altogether. Parliament responded the way legislatures usually do — it amended the constitution again, this time to declare in plain words that its amending power had no limits.

So by the early 1970s the question was no longer academic. Either Parliament could rewrite the constitution into anything at all, or someone had to explain where the limit was and why. Somebody was going to have to blink.

The Birth of the Doctrine: Kesavananda Bharati

The doctrine was born in India popularly known as ‘Kesavananda Bharati Case’. Kesavananda Bharati was the head of a religious monastery in Kerala. He went to court over land reform laws affecting his monastery's property. Nobody expected this case to become one of the most important judgments in the world.

But in 1973, the Indian Supreme Court used his case to answer a much bigger question: can Parliament amend the constitution into something unrecognizable? By a razor-thin majority of 7 to 6, the court said no. Parliament has wide power to amend. But it cannot destroy the "basic structure" of the constitution. Things like democracy, the rule of law, judicial review, and federalism are untouchable; they are the foundation. Everything else is ‘furniture’ which the parliament can amend.

The scale of the case is worth pausing on. Thirteen judges — the largest bench ever assembled there — sat for months and wrote eleven separate opinions. Even today lawyers argue about what exactly the majority agreed on.

The court never gave a complete list of what counts as "basic structure." That was deliberate. Future courts would decide, case by case, which walls are load-bearing and which are just decoration.

And they did. Within two years it was used to strike down an amendment placing an election dispute beyond judicial review, and later to cut back parts of a sweeping amendment passed during the Emergency. It was not a one-off flourish. It became a working tool.

Bangladesh's Turn: The Eighth Amendment Case

Bangladesh borrowed this idea and made it its own. The moment came in 1989, in the case widely known as the Eighth Amendment Case, or Anwar Hossain Chowdhury v. Bangladesh.

The Eighth Amendment had done something quietly dramatic. It decentralized the High Court Division of the Supreme Court, setting up permanent benches outside Dhaka. This sounds harmless. Even helpful. But the Appellate Division saw something deeper. A unified judiciary is one of the pillars holding up the whole constitutional structure of Bangladesh. Splitting it up, they said, broke that pillar.

The court struck down part of the Eighth Amendment. This was a huge moment. It confirmed that Bangladesh's courts, like India's, believed in an unamendable core. Parliament could change many things. But not everything. Some features were beyond its reach, no matter how large its majority.

There was one difference worth noting, and it matters. The Indian court had to build its doctrine almost entirely from inference. Our judges had a textual hook: Article 7, which declares the Constitution the supreme law and the solemn expression of the will of the people, and treats any law inconsistent with it as void. If the Constitution is supreme because the people made it, then Parliament — a creature of that Constitution — cannot turn around and dismantle the thing that created it. The decision was not unanimous. One member of the bench disagreed, and his reasoning is still worth reading, because he asked the obvious question: if the Constitution itself sets out an amendment procedure, who authorised the judges to add extra conditions to it?

When Parliament Tried to Write the Doctrine Into the Text

Now for the strangest chapter, and it is ours.

In 2011, the Fifteenth Amendment inserted Article 7B into our Constitution. Article 7B did something no judge had done: it listed, in black and white, the provisions that could never be amended — the Preamble, Parts I, II and III, and certain other articles — and declared them unamendable by insertion, modification, substitution, repeal or any other means. Alongside it came Article 7A, making the abrogation or suspension of the Constitution a punishable offence.

Read that again. The legislature took a judge-made doctrine about limits on the legislature, and wrote it into the statute book itself. A constitution declaring parts of itself eternal.

It did not end there. In December 2024, the High Court Division held that the provisions of the Fifteenth Amendment which abolished the non-party caretaker government system destroyed a basic structure of the Constitution — democracy — and were void. In the same judgment, the court struck down Articles 7A, 7B and 44(2), and restored the referendum requirement that the amendment had removed from Article 142. The Appellate Division upheld that judgment on 9 July 2026.

Sit with the irony for a moment. Article 7B was the provision that declared certain things unamendable. And it was itself struck down — using the very doctrine it had tried to freeze into text. The foundation, it turns out, is not whatever a Parliament says it is. It is whatever a court is willing to defend.

Why Courts Do This

Skeptics ask an obvious question. Who are unelected judges to override an elected Parliament? Isn't that a bit undemocratic?

The answer courts give is almost poetic. True democracy is not just about majority votes. It is about certain guarantees that protect everyone, including future minorities and future generations, from a majority's worst impulses. If a two-thirds majority could vote away judicial independence, or elections, or fundamental rights, the constitution would become a tool for its own destruction. The Basic Structure Doctrine exists to stop constitutions from committing suicide by amendment.

The criticism does not vanish, though. The doctrine has no fixed content. Nobody voted for it. It hands a small group of judges a veto over the elected branch, on the basis of a standard the judges themselves wrote. Several countries with similar constitutions have looked at it and declined to adopt it. That is simply a different bet about who is more likely to abuse power first.

The Common Thread

Both Kesavananda Bharati and the Eighth Amendment Case share the same spirit. They both draw a line between amending a constitution and replacing it in disguise. They both trust courts, not just legislatures, to guard that line. And they both accept a certain amount of uncertainty. Nobody has a perfect checklist of what is "basic." Judges must decide, one case at a time, generation after generation.

Which brings us back to the house. The will says renovate freely. It does not say which walls are load-bearing. Someone has to walk in, look up, and decide — and then live in whatever is left standing.
