Can a CD recording be trusted as evidence? The Supreme Court says yes, but with a catch.

A politician defected. The proof was a CD. The Supreme Court said it's admissible—but here's the twist. On a recording that could have been edited, copied, or fabricated, the highest court of the land had to decide whether a piece of plastic with digital data could send a man out of his seat in the legislature.

Could a CD—something a child could scratch, a computer could rewrite, or a rival could fake—really be trusted to prove a political defection? The answer, the Supreme Court ruled, is yes. But the price of that yes is a higher standard of proof than almost any other document in a courtroom.

When a CD became the only witness

The case of Jagjit Singh v. State of Haryana began with a political defection in the state. A politician crossed the floor—left his party and joined another. Under the anti-defection law, that move could cost him his seat in the legislature. But proving a defection is rarely simple. There are no signed contracts, no sworn affidavits. Sometimes, the only evidence is what a person said into a microphone.

In this case, the evidence was a CD containing an interview transcript. The recording captured the politician's own words—words that, if genuine, showed he had voluntarily given up his party membership. The prosecution placed the CD before the court. The defence objected: a CD can be tampered with. It can be edited, copied, or fabricated. How could the court rely on something so fragile?

The courtroom fell silent as the CD was produced. It looked ordinary—a thin, reflective disc in a plastic jewel case, no different from a music CD. The surface caught the light from the overhead lamps as the prosecution lawyer placed it on the judge's desk, the plastic case clicking open with a sharp snap. The defence lawyer gestured toward it, a sweep of his hand that dismissed the disc's apparent simplicity. "Your Lordships," he argued, "this device can be scratched, rewritten, or fabricated in minutes. How can the court trust what is on it?" The prosecution, in turn, countered that the recording captured the politician's own voice during the interview, and that its relevance outweighed technical fears of tampering. The core of the dispute was not whether the CD existed, but whether its data was authentic and unaltered.

The bench listened, impassive. The judge's fingers rested on the edge of the jewel case as the defence lawyer pressed his point: the CD could have been edited, copied, or fabricated—there was no way to know without a proper certificate. The prosecution argued that the interview transcript on the CD was direct evidence of the defection, and that the court should not throw out relevant proof simply because it came on a modern device.

The law's old problem with new technology

Indian courts have long struggled with electronic evidence. The Evidence Act, originally written in 1872, never imagined a world where a person's words could be stored on a magnetic disc. For decades, the only admissible evidence was a physical document—a piece of paper with ink on it. A CD, a USB drive, a floppy disk—none of these were documents in the traditional sense.

Parliament tried to fix this. It introduced Sections 65A and 65B into the Evidence Act (special rules for admitting electronic records as evidence). These sections said that electronic records are admissible if they are accompanied by a certificate—a signed statement from the person who created the record, confirming that it was produced by a computer in proper working order and that the data is accurate.

But the law left a gap. What if the certificate was missing? During the hearing, the defence lawyer pointed at the CD and argued that no such certificate had been produced. "Where is the signed statement?" he asked, his voice sharp. "Who created this recording? On what device? Was the computer in proper working order? Without that certificate, this CD is nothing but a piece of plastic." The prosecution shifted in their seats, the absence of the certificate hanging in the air. Could the court still look at it?

And even if the paperwork was perfect, could a CD ever be as reliable as a signed contract? The tension in the room was palpable—the bench had to decide whether a technical omission would defeat a case built on what a man had said into a microphone.

Why the court refused to throw the CD out

The Supreme Court in Jagjit Singh v. State of Haryana faced these questions head-on. The bench observed that "it would be wrong to deny the law the advantages gained by new techniques." Just because a device can be tampered with does not mean every piece of evidence from that device is automatically unreliable.

The court held that electronic records—including data on CD, USB, and floppy disks—are admissible where submitted in accordance with Sections 65A and 65B. The technical requirements of those sections must be followed. But the court also made a crucial observation: technical objections to admissibility based on mere technicality should not prevail if the evidence is relevant.

The judge's tone was firm as he read the observation: it would be wrong, he said, to deny the law the advantages gained by new techniques. The court acknowledged that these devices are inherently susceptible to tampering, but it refused to lay down an exhaustive rule. Instead, it left the door open for judges to assess each piece of electronic evidence on its own facts—but always with a heightened level of scrutiny.

In other words, a judge should not throw out a CD just because the lawyer points out a missing comma in the certificate. The evidence should be looked at, heard, and weighed. But the court added a critical caveat.

The catch: a higher bar for authenticity

Here is the twist the hook promised. The Supreme Court said that while electronic evidence is admissible, the standard of proof of its authenticity and accuracy has to be more stringent than for other documentary evidence.

What does that mean in practice? For a paper document—a letter, a contract, a handwritten note—the court usually presumes it is genuine unless someone proves otherwise. The burden is on the person who challenges it. But for a CD or a USB drive, the burden is reversed. The person who presents the electronic evidence must prove that it has not been tampered with. The court will not assume it is authentic just because it exists.

This makes practical sense. A paper document leaves physical traces of tampering—erased ink, torn edges, mismatched handwriting. A CD can be copied perfectly, edited invisibly, and presented as original. The only way to trust it is to verify its chain of custody: who created it, when, on what device, and whether anyone else had access to it. The court's reasoning was that the very advantages of new techniques—ease of copying, editing, and storage—also make them vulnerable to abuse. Therefore, a more stringent standard of proof is required.

The court did not lay down an exhaustive rule for how this verification must happen. It recognised that technology changes too fast for rigid rules. Instead, it left the door open for judges to assess each piece of electronic evidence on its own facts—but always with a heightened level of scrutiny.

What this means for every lawyer and litigant

The judgment in Jagjit Singh v. State of Haryana is not just about political defection. It applies to every case where electronic evidence is used—corporate disputes, criminal trials, family court battles, and defamation suits. If you want to rely on a CD, a USB drive, an email printout, or a WhatsApp chat, you must do two things.

First, comply with Sections 65A and 65B. Get the certificate. Get it signed by the person who operated the computer or device. Keep the original device safe. Second, be prepared to prove authenticity beyond the certificate. The court may ask: who had access to the device? Was it password-protected? Was it ever left unattended? Can you produce the original recording device?

THE PLAY: Before you submit any electronic evidence, prepare a chain-of-custody affidavit that names every person who handled the device, every date it was accessed, and every software used to copy or transfer the data.

The recording that changed the rules

The politician lost his seat. The CD was admitted. The Supreme Court upheld the defection. But the real legacy of Jagjit Singh v. State of Haryana is not the outcome of one case. It is the recognition that Indian courts will not hide from technology. They will admit electronic evidence—but they will demand proof that it is real.

The CD could be trusted. But only because the court asked the right questions first.
