Can illegal search evidence be used in court?
Two Supreme Court rulings clash: one says relevancy trumps illegality, the other says privacy violations can shut out evidence.
Admissible.
The broken lock
The admissible goods.
Two Supreme Court rulings clash: one says relevancy trumps illegality, the other says privacy violations can shut out evidence.
Police found the goods during an illegal search. The Supreme Court said: that doesn't matter.
On a Delhi afternoon, inspectors broke open a lock. They walked into a godown without a valid warrant. Inside, they found what they were looking for — goods that would form the backbone of a tax evasion case. The owner of the goods did not argue about what was found. He argued about how it was found.
The question was simple and terrifying in its implications: could the state use evidence it had no legal right to obtain?
When the lock was broken
The case of Pooran Mal v. Director of Inspection (Investigation) began with a search that everyone agreed was illegal. The inspectors had no valid warrant. The lock they broke was not theirs to break. The godown they entered was private property. And yet, once inside, they found goods that pointed squarely at tax evasion.
The person whose godown was searched did not deny that the goods existed. He argued that the evidence could not be used against him because it had been obtained through an illegal search. The trial court and the High Court both admitted the evidence. The matter reached the Supreme Court, where a Constitution Bench was assembled to settle the law once and for all.
The air in the courtroom was thick with the weight of the question. The bench, five judges deep, sat behind a curved dais of dark wood. The file before them was thin — a single appeal, but one that could redraw the boundaries of state power. The petitioner's counsel spoke of trespass, of broken locks, of the sanctity of private property. The respondent's counsel spoke of tax evasion, of public revenue, of the need for evidence to reach the truth. Between them lay the godown's inventory list, its pages still smelling of dust and old paper.
The test that mattered
The Supreme Court looked at how English courts had handled the same problem. In the English case Kuruma v. R, the court had held that the method of obtaining evidence did not determine its admissibility. What mattered was whether the evidence was relevant to the case.
The Constitution Bench adopted this reasoning. The court observed that the test to be applied, both in civil and criminal cases, in considering whether evidence is admissible "is whether it is relevant to the matters in issue. If it is, it is admissible and the Court is not concerned with how it was obtained."
This was a sweeping statement. It meant that a police officer could break down a door without a warrant, find stolen goods inside, and those goods could still be used as evidence. The illegality of the search did not infect the evidence itself. The courtroom fell silent as the judgment was read. The petitioner's counsel sat still, the logic of the court pressing down on him. The respondent's counsel allowed himself a small nod. The law, as the court saw it, was not about punishing the police for their mistakes. It was about whether the evidence could help the court decide the case.
The court noted that even if a search was unjustified by a warrant or illegally conducted, the court maintained a discretion to admit the evidence. That discretion was not a loophole — it was a recognition that the court's primary duty was to the truth, not to the procedural purity of the search that uncovered it.
The one exception the court left open
The court did not give the state a blank cheque. It added a crucial qualification: evidence obtained through an illegal search could be shut out if there was "an express or necessarily implied prohibition in the Constitution or other law."
In other words, if the Constitution itself said that certain evidence could not be used, or if a statute specifically barred it, then the court would exclude it. But in the absence of such a prohibition, relevancy was the only test. The court concluded that in India, as in England, where relevancy is the test of admissibility, "unless there is an express or necessarily implied prohibition in the Constitution or other law evidence obtained as a result of illegal search or seizure is not liable to be shut out."
This became the universal legal parameter: relevancy prevails unless specifically prohibited. The judgment was signed, the file was closed, and the godown's inventory — obtained through a broken lock — became admissible evidence. The law was settled. But the exception the court had carved out would wait, like a dormant seed, for the right case to bring it to life.
When the phone recording arrived
Decades later, a very different case reached the courts. In Vishal Kaushik v. Family Court, the question was not about goods found in a godown. It was about words recorded on a phone.
The Husband (Petitioner) wanted to introduce tape-recorded conversations with his wife as evidence in family court proceedings. The Wife (Respondent) objected. She said the conversations had been recorded without her knowledge or consent. This, she argued, was a violation of her right to privacy.
The family court's atmosphere was different from the Supreme Court's grand chamber. It was smaller, more intimate, the kind of room where personal lives were laid bare. The Husband (Petitioner) sat on one side, his lawyer holding a small cassette player. The Wife (Respondent) sat on the other, her eyes fixed on the floor. The judge looked at the cassette player, then at the law books on the shelf. The question was not whether the conversation had happened — it was whether the court could listen to it at all.
The court had to decide whether the exception from Pooran Mal applied here. Was there a "necessarily implied prohibition" in the Constitution that would shut out this evidence?
The constitutional violation that shut the door
The court found that there was. It reasoned that if the means adopted by the Husband (Petitioner) to obtain the evidence are "not permissible within the framework of the Constitution of India," by tape recording conversation with his wife without her knowledge and consent, the resulting evidence would be "wholly inadmissible in evidence."
The logic was direct: "recording of such conversation had breached her 'right to privacy', one of the facets of her 'right to liberty' enshrined under Article 21 of the Constitution of India."
Article 21 (the fundamental right to life and personal liberty) had been interpreted by earlier Supreme Court judgments to include a right to privacy. Recording someone's private conversation without their knowledge was a violation of that right. And because the Constitution itself prohibited such violations, the evidence obtained through them could not be used.
The court concluded that the alleged telephonic conversation, even if true, "would thus not be admissible/receivable in evidence." The Wife (Respondent) could not even be required to admit or deny the content or provide a voice sample for comparison. The cassette player was set aside. The conversation remained unheard. The constitutional line had been crossed, and the evidence fell on the other side.
This verdict highlighted that a serious constitutional violation (breach of Article 21 privacy) can constitute the "necessarily implied prohibition" leading to exclusion in certain contexts, particularly matrimonial cases. The distinction was not in the rule — it was in the nature of the right that had been violated.
Two rulings, one thread
At first glance, Pooran Mal and Vishal Kaushik seem to point in opposite directions. One says illegal searches produce admissible evidence. The other says illegally recorded conversations are inadmissible.
But the thread that connects them is the same. Both cases apply the same principle: relevancy is the default test, but a constitutional violation can override it. In Pooran Mal, there was no constitutional violation — the search was illegal under statute, but the Constitution did not bar the use of the evidence. In Vishal Kaushik, the recording violated Article 21, and the Constitution itself provided the "necessarily implied prohibition" that Pooran Mal had left room for.
The difference is not in the rule. The difference is in whether the method of obtaining the evidence crossed a constitutional line. The godown's broken lock was a statutory wrong, remediable by a complaint or a civil suit, but it did not touch the Constitution. The wife's recorded conversation, on the other hand, reached into the core of her personal liberty — a right that the Constitution had placed beyond the reach of the state and, in this context, beyond the reach of a private individual seeking to use the court's machinery.
Together, the two cases draw a map. The default path is admission: if the evidence is relevant, it comes in, no matter how it was obtained. But there are red lines on that map — constitutional prohibitions that, when crossed, make the evidence disappear. The lawyer's job, and the judge's duty, is to know where those lines are drawn.
THE PLAY: Before moving to exclude evidence obtained through an illegal search or seizure, identify the specific constitutional provision or statute that creates the "necessarily implied prohibition" — without it, the court will admit the evidence regardless of how it was obtained.
The court ended where it began: with a locked godown and a recorded conversation, and the same question hanging over both. The answer, in the end, was not about the lock or the recording. It was about whether the Constitution had something to say about the way the evidence was gathered. If it did, the evidence fell. If it did not, the evidence stood. And the court, in both cases, simply followed where the Constitution led.
