Arbitrators Can't Decide Without Any Evidence, Says High Court

The arbitrators made a decision. But they didn't look at a single piece of evidence.

No witness was called. No document was filed. No paper was marked as an exhibit. The three arbitrators simply heard the lawyers argue, then passed an award. One side won. The other side did what almost no one does: they did not attack the merits of the award. They attacked the process itself. They said the arbitrators had no right to decide anything because they had never looked at any evidence at all.

On the table where the award lay, it was a single-page document — thin, final, and empty of any reference to a single document or witness. The exhibit book beside it was blank.

The case is Hoogly River Bridge Commissioners v. Bhagirathi Bridge Construction Co. — a commercial dispute over a construction contract. The two sides chose arbitration (a private dispute resolution process where parties pick their own judges instead of going to court). They appointed three arbitrators. The arbitrators heard arguments. Then they passed an award. One side was happy. The other side was not.

The losing party did something unusual. They did not argue that the arbitrators got the facts wrong. They did not argue that the law was misapplied. They argued that the entire proceeding was void from the start. Their complaint: the arbitrators had made their decision without a single piece of evidence. No documents were marked as exhibits. No witnesses were examined. No oral testimony was recorded. The arbitrators had simply listened to the lawyers and then decided.

When the award arrived without a paper trail

The Calcutta High Court looked at the record. What they found was striking. There was no evidence — not a single piece of paper, not a single statement under oath. The arbitrators had not called for any documents. They had not examined any witnesses. They had not asked either side to prove its case through the ordinary methods that courts and tribunals use to separate fact from fiction. The courtroom fell silent as the bench noted the empty file before them.

The party challenging the award argued that this was a fundamental violation of natural justice (the basic legal principle that a decision-maker must give each side a fair opportunity to present its case). Without evidence, they said, the arbitrators had no basis to decide anything. The award was not just wrong — it was legally void.

The other side pushed back. Their argument was simple: arbitration is meant to be flexible. Parties choose arbitration precisely because it is faster and less formal than court. The arbitrators had heard the lawyers. They had understood the dispute. That was enough. The law did not require a full trial with exhibits and witnesses.

Why the court said evidence is not optional

The Calcutta High Court rejected that argument. The bench observed that it was "absolutely not worried about the merit of the case" — meaning the court was not going to second-guess whether the arbitrators reached the right conclusion on the facts. That was not the issue. The issue was whether the process itself was fair. The smell of old paper and the weight of the thin case file seemed to underline the point.

The court held that "the principle of natural justice and reasonable or fair play in real life requires some basic evidence either oral or documentary before the arbitrators which would empower them to arrive at a just and reasonable conclusion." In plain language: even in arbitration, you cannot decide a dispute in a vacuum. There must be something — a document, a witness, an admission — that gives the decision-maker a factual foundation to stand on.

The court did not say that arbitration must follow every technical rule of evidence that applies in a civil trial. But it did say that the process cannot be so bare that the arbitrators are essentially guessing. Natural justice requires a minimum threshold: some evidence, of some kind, that the arbitrators actually considered before they ruled.

Because the record showed no evidence at all — no oral testimony, no documentary proof — the High Court set aside the arbitration award. The decision was quashed (cancelled as legally invalid). The parties would have to start over, or find another way to resolve their dispute.

How the dispute reached the arbitrators

The underlying contract between the Hoogly River Bridge Commissioners and Bhagirathi Bridge Construction Co. involved the construction of bridge infrastructure. When a dispute arose over performance or payment under that contract — the specifics of which the court did not need to examine — the parties invoked the arbitration clause. The clause provided for a three-member tribunal, a common arrangement in large infrastructure contracts where each side appoints one arbitrator and the two appointed arbitrators choose a third.

The tribunal was constituted. The parties filed their pleadings — statements of claim and defence — laying out their respective positions. Then the hearings began. The lawyers for both sides appeared before the tribunal and made their submissions. They argued the law. They argued the facts. They cited clauses from the contract. They referred to correspondence, though none of it was formally tendered as evidence.

At no point did any arbitrator ask: "Where is the document you are referring to?" At no point did any arbitrator say: "We need to see this letter or that report before we can decide." The hearings concluded. The tribunal retired to deliberate. And then, without ever having looked at a single piece of paper that was marked as an exhibit, without having heard a single witness under oath, the arbitrators passed their award.

The award was a short document. It stated the names of the parties, the fact that the tribunal had been constituted, that hearings had been held, and then it announced the decision. There was no list of exhibits. There was no reference to any oral testimony. There was no analysis of any documentary evidence — because there was none to analyse.

The losing party's unusual challenge

Most parties who lose an arbitration award attack it on the merits. They argue that the arbitrators misread the contract, or misapplied the law, or got the facts wrong. The losing party in this case did none of that. Instead, they went to the Calcutta High Court under the provision of the Arbitration and Conciliation Act, 1996 that allows a court to set aside an award for violation of natural justice.

Their petition was narrow and focused. They did not claim that the arbitrators should have decided differently. They claimed that the arbitrators had no right to decide at all — because they had never received any evidence that would legally empower them to reach a conclusion. The entire proceeding, they argued, was a sham. Lawyers had spoken. Arbitrators had listened. But no facts had been proved. No evidence had been tested. The award was a decision without a foundation.

The responding party — the one that had won before the tribunal — argued that the challenge was an abuse of process. Arbitration, they said, is meant to be a streamlined, efficient alternative to litigation. Parties choose it to avoid the delays and technicalities of court. The arbitrators had heard the lawyers. The lawyers had referred to the contract and the correspondence. That was enough. To require formal marking of exhibits and examination of witnesses would defeat the very purpose of arbitration.

The court's reasoning in detail

The Calcutta High Court began its analysis by making clear what it was not doing. The bench stated that it was "absolutely not worried about the merit of the case." This was a critical clarification. The court was not going to examine whether the arbitrators reached the right conclusion. It was not going to re-weigh the facts or re-interpret the contract. The court's role was limited to examining the process by which the award was made.

And when the court examined that process, it found a fundamental defect. The record of the arbitration contained no evidence. Not one document had been marked as an exhibit. Not one witness had been examined. Not one statement had been made under oath. The arbitrators had nothing before them except the oral arguments of the lawyers.

The court then articulated the core legal principle. It held that "the principle of natural justice and reasonable or fair play in real life requires some basic evidence either oral or documentary before the arbitrators which would empower them to arrive at a just and reasonable conclusion."

The key word in that sentence is "empower." The court was saying that evidence is not just a formality — it is what gives the arbitrator the authority to decide. Without evidence, the arbitrator has no power to reach a conclusion because there is nothing to base that conclusion on. The decision becomes an exercise in guesswork, not judgment.

The court did not prescribe any particular form that the evidence must take. It did not say that arbitration must follow the Indian Evidence Act. It did not require that every document be formally exhibited or that every witness be cross-examined. What it required was something far more basic: that there be some evidentiary foundation, of whatever kind, that the arbitrators actually considered before they ruled.

Because the record in this case showed no such foundation, the court set aside the award. The decision was quashed as legally invalid. The parties were left to start over — either by reconstituting the tribunal and conducting a proper hearing with evidence, or by negotiating a settlement, or by pursuing any other remedy available to them under the law.

What this means for arbitration in India

This judgment is a reminder that arbitration is not a law-free zone. Parties who choose arbitration to avoid the delays of court cannot also avoid the basic requirements of fairness. An arbitrator who decides without evidence is not being efficient — they are being arbitrary. And an arbitrary decision, no matter how fast, is not worth the paper it is written on.

For practitioners, the lesson is straightforward: if you are appearing before an arbitral tribunal, make sure there is a record. File your documents. Mark your exhibits. If you rely on a witness, examine them. If you rely on a contract, put it before the arbitrator. The award will only survive a challenge if the record shows that the arbitrators actually considered evidence — not just arguments. The silent witness box in the arbitration hearing room should never remain empty.

The implications extend beyond this single dispute. Every arbitration clause in every commercial contract in India now carries this implicit warning: evidence is not optional. Arbitrators who skip the evidentiary stage risk seeing their awards struck down. Parties who fail to insist on a record risk losing their case — not on the merits, but on the process.

For the construction industry, where arbitration is the default dispute resolution mechanism, this judgment adds a layer of procedural discipline. A contractor who wins an award without putting a single document on record may find that victory is hollow. A commissioner who loses such a case may find the award set aside, but only after years of litigation and cost.

The Calcutta High Court's reasoning also signals a broader principle: natural justice in arbitration cannot be contracted away. Even if the parties agree to a "documents-only" arbitration — a common arrangement in commercial disputes — the tribunal must still ensure that there is some evidentiary basis for its decision. A bare agreement to dispense with evidence entirely would likely be unenforceable.

THE PLAY: Before an arbitral tribunal closes proceedings, confirm on record what evidence — oral or documentary — has been presented; an award without any evidentiary foundation is void for violation of natural justice.

THE TEST: If the arbitral record contains no marked exhibits, no sworn testimony, and no documentary proof, the award is liable to be set aside — regardless of the merits of the decision.

WHAT THIS MEANS: Every arbitration in India now carries an implicit evidentiary floor. Arbitrators who skip the evidence stage are not being efficient — they are being arbitrary. And an arbitrary award, however fast, is legally worthless.

The arbitrators made a decision. But they didn't look at a single piece of evidence. The High Court said that is not arbitration — it is an empty verdict, as hollow as the blank exhibit book that sat untouched throughout the proceedings.
