Imagine an arbitrator hands down an award against you for a few crore rupees, and when you read it you find the reasoning rests on a single sentence buried in your own statement of defence, a line the tribunal has read as an admission of liability. The rest of your defence, which disputed the claim in detail, and the emails in which you actually denied owing the money, were never weighed. This is not a hypothetical. It is close to what happened in a real Bombay High Court case, and the court set the award aside. The principle behind that result is one of the most practical rules in Indian arbitration: a claim must be specifically pleaded and proved, and an admission cannot be assumed from a stray line or a letter.
Arbitration is faster and less formal than a court trial, but it is not lawless. The claimant still has to set out its case properly, and the respondent is entitled to have its whole defence read, not just the part that helps the other side. When tribunals shortcut this by treating ambiguous words, isolated sentences, or correspondence as conclusive admissions, the resulting award becomes vulnerable under Section 34 of the Arbitration and Conciliation Act. Understanding why protects you whether you are pursuing a claim or defending one.
Pleadings are the foundation: what Section 23 requires
Every arbitration begins with pleadings. Section 23 of the Arbitration and Conciliation Act, 1996 requires the claimant to state the facts supporting the claim, the points at issue, and the relief or remedy sought, and requires the respondent to state its defence to those particulars[1]. That language is doing real work. A claim is not a vague grievance. It is a specific assertion of facts, a defined dispute, and a quantified relief, and it is on that pleaded case, and nothing wider, that the tribunal is asked to rule. Filing these statements is not a formality the parties can quietly skip. The Bombay High Court in Rajesh Pravinchand Rajyagor v. Nitin Harjivandas Rajyagor set aside an award where no statement of claim or defence had been filed at all, holding that filing pleadings is mandatory and not something a tribunal can dispense with[2]. If the claim is not on the record in clear terms, there is nothing for the tribunal to adjudicate and nothing for the respondent to answer.
An admission must be clear, unequivocal, and unconditional
Sometimes a party does concede something, and a tribunal or court can act on a genuine admission without making the other side prove what is already accepted. But the threshold for treating words as an admission is high, and it is borrowed from the settled law on judgments on admission under Order XII Rule 6 of the Code of Civil Procedure. The Calcutta High Court distilled the test in Manick Chand Jajodia v. Lalchand Agarwal, where a supposed admission was fatally undercut by a single hedging word[3].
The admission must be clear, unequivocal, unconditional and unambiguous so that there may not be any necessity for the court to wait till determination of other questions. The admission must be taken as a whole unless the part of the claim which the court proposes to allow on admission is severable from other parts of the claim.
Because the word approximately appeared in the document, the alleged admission was held to be ambiguous, and the decree built on it was set aside. The case law is full of similar near-misses that did not qualify. The Madras High Court in C.J. Sheth Construction Company v. Sunderdas Arjunlal refused to treat a reply notice as an admission where the defendant had in fact disputed liability[4]. The Delhi High Court in Dena Bank v. Bindal Construction held that a debtor saying it had every desire to return the correct amount was not an admission of any specific sum, because it admitted no figure at all[5]. The same court in Ashok Leyland Finance v. Maruti Udyog, relying on the Supreme Court in Chikkam Koteswara Rao v. Chikkam Subbarao, required an admission to be clear, conclusive, and unambiguous before it could ground a decree[6], and the Gauhati High Court in Buragohain Tea Co. v. Cosmos Business insisted that an admission be specific, clear, and unambiguous, treating a contrary finding as perverse[7]. The thread running through all of them is the same. An admission that needs interpretation, or that contradicts other parts of the pleading, is not an admission at all.
You cannot pluck an admission from a single line or a letter
The clearest application of this rule to arbitration is Sphere International v. Ecopack India Paper Cup Pvt. Ltd. A supplier claimed payment for goods. The buyer filed a detailed statement of defence disputing the claim in several paragraphs and pointing to a settlement sheet and a chain of emails showing that, after adjustments, the buyer was actually owed money. The arbitral tribunal seized on one paragraph of the defence, read it as an admission of liability, and made an interim award on that basis without letting the parties lead evidence. The Bombay High Court set the award aside as patently illegal[8].
The arbitral tribunal could not have picked up an isolated sentence from the entire pleading, which pleadings clearly indicated that the claim of the respondent was disputed by the petitioner. An interim award can be made only if the alleged admission of liability is clear, unambiguous and definite and does not require any evidence to prove such admission at the stage of trial.
Two points in that judgment matter for everyday practice. The first is that pleadings are read as a whole. As the court put it, admissions in pleadings cannot be dissected, and a concession in one paragraph cannot be lifted out and used while the denials in the surrounding paragraphs are ignored. The second is that the correspondence cuts against the tribunal as easily as for it. The very emails the claimant might wave around to suggest the debt was accepted also recorded that amounts were on hold and disputed, so the letters proved there was a live dispute, not an admission. A tribunal that wants to act on an admission has to find one that is positive, unequivocal and clear, in the words the court borrowed from earlier authority, and that does not need evidence to establish. Anything short of that has to go to trial.
Silence is not an admission either
If an ambiguous concession is not an admission, neither is saying nothing. Section 25 of the Arbitration and Conciliation Act is explicit: where a respondent fails to communicate in its statement of defence, the tribunal must continue the proceedings without treating that failure, in itself, as an admission of the claimant's allegations[9]. The claimant still has to prove its claim. The Delhi High Court applied this directly in PCI Ltd v. Paragon Cable India, where the respondent had not filed a defence and the arbitrator simply allowed every claim. The court set aside the claims that had been granted without evidence, holding that a default in filing a defence cannot be converted into proof of the amounts claimed[10]. A claimant who turns up with an unanswered claim has won nothing yet. It still has to put its pleaded case to proof.
An award cannot travel beyond the pleadings
The flip side of the rule protects the respondent differently. Even a claim that is fully proved cannot be awarded beyond what was pleaded and referred. The Supreme Court made this plain in Oil and Natural Gas Corporation Ltd v. Off-Shore Enterprises, where a tribunal awarded a figure many times larger than the amount ONGC had actually claimed[11].
The claimant did not reserve the liberty to modify the claim, nor did it amend the claim before the Arbitral Tribunal. Therefore, any award by the Arbitrators in excess of the amount claimed was wholly without jurisdiction as not being the subject matter of reference to the Arbitral Tribunal and being an award beyond the pleadings.
The Supreme Court in the case of M/s. MSK Projects (I) (JV) Ltd v. State of Rajasthan[13] had clearly held in its ruling that when an arbitral tribunal passes an award, the same cannot adjudicate on issues/prayers not pleaded or by either of the parties in its pleadings and is liable to be set aside. The Supreme Court again followed the same in the case of SEPCO Electric Power Construction Corp. v. GMR Kamalanga Energy Ltd.[14]
The Punjab and Haryana High Court applied the same logic in Punjab Housing Board v. Roshan Lal Ghai, striking down an award that granted far more than the sum the claimant had put in issue, on the ground that an arbitrator cannot enlarge the scope of the reference on its own[12]. The pleaded claim sets the outer limit of the award. What is not asked for cannot be given, and a relief that was never specifically claimed cannot be read into the case after the fact.
What this means in practice
For a claimant, the discipline is unglamorous but decisive. Plead the claim properly and do not rely on the other side's letters to do the work for you.
State the claim in full in the statement of claim: the facts, the points at issue, the precise relief, and the exact amount, because that pleaded figure is the ceiling on what you can be awarded.
Do not treat an email as a substitute for pleading. Correspondence is evidence to be proved, not a pleaded admission, and a letter that mentions a figure usually mentions a dispute around it too.
Amend if your claim grows. Section 23 lets you amend or supplement the claim during the proceedings, so if the quantum changes, put it on the record rather than hoping the tribunal will award more than you asked for.
For a respondent, the protections are real but you have to claim them. Plead your defence fully and deny the claim specifically, paragraph by paragraph, so that no single concession can be lifted out of context. If you accept a figure for one purpose, such as an adjustment, say so expressly and tie it to the qualification. And if a tribunal makes an award by treating a stray sentence, a letter, or your failure to file in time as an admission, that is exactly the kind of patent illegality and excess of jurisdiction that a Section 34 challenge exists to correct.
Common mistakes and misconceptions
The first misconception is that a letter or email admitting a number is the same as a pleaded and proved claim. It is not. Correspondence has to be put in evidence and read as a whole, and the same exchange that looks like an acceptance often records a dispute. The second is that a single conceding sentence in the opponent's pleading wins the case. Pleadings are read together, and a concession surrounded by denials is ambiguous, which under the settled test means it is no admission at all.
The third is that a respondent who does not file a defence has admitted everything. Section 25 says the opposite, and PCI Ltd shows that the claim still has to be proved on evidence. The fourth is that an arbitrator can do broad justice by awarding whatever the facts seem to justify. The tribunal is confined to the claim that was pleaded and referred, and ONGC confirms that anything beyond it is made without jurisdiction. Each of these mistakes produces an award that looks strong on the day it is delivered and unravels on challenge.
The bigger picture
It is tempting to see all of this as a technicality, the kind of pleading formality that arbitration was meant to escape. It is the opposite. Requiring a claim to be specifically pleaded, and an admission to be clear and unequivocal, is what keeps an award honest. It forces the claimant to commit to a definite case that the respondent can meet, it stops a tribunal from manufacturing liability out of a phrase or a letter, and it confines the award to the dispute the parties actually agreed to arbitrate. The structure of Section 23, reinforced by Section 25, is built around exactly this idea, as commentaries on the statement of claim and defence explain, and the text of Section 23 itself ties the relief a tribunal can grant to the relief that was sought. If you remember one thing from the case law, remember this: in arbitration, you win on what you plead and prove, not on what you can read into the other side's letters.
