In short. Yes, you can challenge a DIAC award under Section 34 of the Arbitration and Conciliation Act, 1996. But the grounds are narrow, and you get three months from receiving the signed award, plus 30 more days only if you show sufficient cause. Not a day after that. This is for a business that has lost, or partly lost, an arbitration at the Delhi International Arbitration Centre. The court won't rehear your case. Expect a year or more for a decision. Today, write down the date the award reached you and diary the last date.
Is this your situation?
- The DIAC award went against your company, and reading it, you're sure the tribunal got it wrong.
- The award came by email one day and by courier a week later. Now nobody in the office agrees on when the three months began.
- The tribunal leaned on a document you never got to answer, or shut down a cross-examination you badly needed.
- The award gives the other side something it never asked for, or something your contract specifically ruled out.
- The award holder's lawyer has already written demanding payment. Does filing a challenge stop that?
- You won. Then a Section 34(5) notice from the other side turned up in your inbox.
- It's a big award, and you need to know whether this goes to the Delhi High Court or to a district court at Saket or Tis Hazari.
Can you challenge a DIAC award under Section 34? The short answer
Yes. A DIAC award is an arbitral award like any other under Part I of the Arbitration and Conciliation Act, 1996. The only way to get it set aside is a petition under Section 34 of that Act. There's no appeal on facts and no retrial. The court asks two narrow questions. Does the award fall within one of the grounds Parliament listed? And was the petition filed in time?
The deadline doesn't bend. Under Section 34(3) you get three months from the day you received the signed award. Miss that, and the court can allow up to 30 more days if you show sufficient cause. Nothing beyond. Back in 2001, in Union of India v. Popular Construction Co., the Supreme Court held that the general power to condone delay under Section 5 of the Limitation Act, 1963 doesn't apply here.
Frankly, you can challenge it. But you need a real legal flaw in the award or in how the case was run. A strong feeling that the tribunal misread the facts isn't enough.
What a Section 34 challenge is, and what it isn't
It isn't an appeal. The judge won't reweigh the evidence, pick one witness over another, or swap in a personal reading of the contract where the tribunal's reading was a reasonable one. The Supreme Court spelt this out in Ssangyong Engineering v. NHAI (2019), after the 2015 amendments cut down the grounds. If the tribunal's view is a possible view on the evidence and the contract, it'll usually stand. Even if the judge would have gone the other way.
Since the 2019 amendment, a party has to make out its case under Section 34(2)(a) 'on the basis of the record of the arbitral tribunal'. In plain terms, the petition is argued on the pleadings, documents, evidence and orders that were in front of the tribunal. Fresh evidence is rarely let in. If a document never went before the DIAC tribunal, assume it's no use to you now. Harsh, but that's the law.
The Section 34 time limit: how the three months and the 30 days work
| What happens | What it does to your deadline |
|---|---|
| The signed award reaches you | Your three months under Section 34(3) start from the day your company actually gets a signed copy of the award (Section 31(5)). |
| You ask the tribunal to correct or interpret the award under Section 33 | If you ask within 30 days of getting the award, the three months run from the date the tribunal deals with that request. |
| The three months run out | File by this date. If it falls on a day the court is shut, you can file on the next working day (Section 4, Limitation Act). |
| The extra 30 days | Only if you show sufficient cause for the delay. Whether to allow it is up to the court. |
| Day 31 after the three months | No court can hear the petition. For practical purposes the award is final. |
| The 30 days end during a court vacation | No extension. In My Preferred Transformation and Hospitality v. Faridabad Implements (Supreme Court, 10 January 2025), a petition filed once the Delhi High Court reopened after its summer vacation was held time-barred, because the three months had ended on a working day. |
When does the clock start on a DIAC award?
Time runs from when the party receives the signed award. Not from the date typed on it, and not from the last hearing. Courts have held that what counts is delivery to the party itself, and a copy that reaches only your lawyer may not do. DIAC tribunals often send the award through the Centre, by email and by courier. Keep the email. Keep the courier receipt and any covering letter. If anyone ever disputes when you got the award, that's your proof.
A Section 33 request to fix a typo or an arithmetical error can push the start date back. But only if it's genuine and made within 30 days. A request that's really an attempt to reopen the case won't buy you any time.
When Advocate B.K. Singh opens a new Section 34 file, he writes two dates on the cover before anything else: the date of receipt, and the last date to file. Both are worked out from the documents, never from memory. Almost anything else in a file can be fixed later. A missed limitation date can't.
The grounds for challenging a DIAC award under Section 34
Section 34(2)(a)(i): incapacity of a party
A party was under some incapacity. Think of a minor, someone of unsound mind, or, in business terms, an entity that couldn't legally bind itself the way the agreement assumed. You'll rarely see this in commercial disputes.
Section 34(2)(a)(ii): invalid arbitration agreement
The arbitration agreement isn't valid under the law the parties chose, or under Indian law. The usual arguments are that your company never signed or accepted the contract carrying the clause, or that the clause doesn't cover this kind of dispute. If you raised this before the tribunal under Section 16 and lost, you can raise it again here.
Section 34(2)(a)(iii): no proper notice or no fair chance to present your case
You weren't properly told about the arbitrator's appointment or the proceedings, or you couldn't present your case for some other reason. This is for serious breaches of natural justice. The tribunal relied on a document you never saw, say, or decided the case on a point nobody argued.
Section 34(2)(a)(iv): award beyond the scope of the reference
The award deals with a dispute that was never referred, or decides things outside what was submitted. Can the bad part be cut away from the good? Then only the bad part goes, and the rest of the award survives intact.
Section 34(2)(a)(v): tribunal or procedure not as agreed
The tribunal wasn't made up, or the procedure wasn't followed, as the parties agreed. At DIAC, that includes its Rules. The exception is where the agreement itself clashed with a mandatory part of the Act.
Section 34(2)(b)(i): dispute not arbitrable
Indian law doesn't let this subject matter go to arbitration at all, typically because a statute keeps it for a special court or tribunal of its own.
Section 34(2)(b)(ii): conflict with the public policy of India
Since the 2015 amendment, this covers only three situations. One, the award was induced or affected by fraud or corruption, or made in breach of the confidentiality or admissibility rules in Sections 75 and 81. Two, it contravenes the fundamental policy of Indian law. Three, it conflicts with the most basic notions of morality or justice. The Explanation to the section makes clear the court won't review the merits of the dispute to test this.
Section 34(2A): patent illegality on the face of the award
In domestic arbitrations (not international commercial ones), an award can also be set aside if patent illegality appears on its face. The same subsection says an award isn't to be set aside just because the law was wrongly applied, or by reappreciating the evidence. In Ssangyong, the Supreme Court gave examples: an award with no reasons, a finding based on no evidence or one that ignores evidence going to the root of the matter, or a view of the contract no fair-minded person could take.
Objections that usually go nowhere in a Section 34 petition
- "The tribunal believed their witness, not ours." Weighing evidence is the tribunal's job. Unless the finding rests on no evidence at all, the court won't step in.
- "The contract can be read our way." If the clause can reasonably carry the tribunal's reading, the court leaves it there, even if yours is reasonable too.
- "The damages are far too high." Quantum turns on evidence. You'll only succeed if there's no basis for the figure at all, or the tribunal gave something the contract expressly barred.
- "We've found a document that proves everything." Section 34 is decided on the tribunal's record. A document you didn't produce in time rarely helps now.
- "The award is long and makes no sense." Bad drafting isn't a ground. Lack of reasons is. An award that gives reasons you can follow, even short ones, will usually survive.
Points that come up in DIAC award challenges in particular
The DIAC Rules are part of your agreement. When you agree to DIAC arbitration, the DIAC (Arbitration Proceedings) Rules, 2023 become the procedure you've agreed to. Breaking those rules can support a ground under Section 34(2)(a)(v), but only if the breach was serious and actually hurt you. A small slip in the timetable won't do.
Raise objections to the arbitrator early. If you knew facts pointing to bias and didn't challenge the arbitrator within the time allowed (15 days under Section 13 by default, 14 under DIAC's own challenge rule), or didn't object at all, it's hard to raise the point for the first time in a Section 34 petition. Section 4 of the Act treats an objection you didn't raise as waived in many situations. The exception is ineligibility under Section 12(5) and the Seventh Schedule, which can be waived only by an express written agreement made after the dispute arose. Our guide on challenging a DIAC arbitrator goes into this.
Fee defaults and terminated claims. Under Rule 33.5 of the 2023 Rules, a claim or counter claim can be terminated if its deposit isn't paid within 30 days of falling due. In Samsung India Electronics v. Delhi International Arbitration Centre (Delhi High Court, 18 March 2026), the court upheld separate assessment of fees where one side wouldn't pay its share. Parties who lost a counter claim this way often want to attack the final award for it. That's a weak argument where the Centre followed its rules and gave notice. Our guide on what happens when the other side won't pay DIAC fees explains more.
Emergency arbitrator orders and interim orders aren't awards. You don't challenge an order of a DIAC emergency arbitrator, or an interim order of the tribunal under Section 17, under Section 34. Section 17 orders have their own appeal under Section 37(2)(b). Only the final award, or a separate interim award that finally settles some issue, can be challenged under Section 34.
Which court hears a Section 34 petition against a DIAC award?
The petition goes to the 'court' defined in Section 2(1)(e) of the Act, and that depends on the seat of the arbitration. Most DIAC arbitrations are seated in New Delhi or Delhi, which gives the Delhi courts exclusive jurisdiction. But if your contract picked DIAC as the institution and some other city as the seat, that city's courts hear the challenge. Read the clause before deciding where to file. It takes five minutes.
Inside Delhi, the court depends on value. Section 10 of the Commercial Courts Act, 2015 sends challenges in arbitrations of commercial disputes of specified value (Rs 3 lakh and above) to the commercial courts. Section 12(4) of that Act takes the claim and counter claim in the arbitration, added together, as the value. Above Rs 2 crore, the petition goes to the Delhi High Court's Commercial Division, where it's registered as an O.M.P. (COMM.). Below that, it goes to the District Judge (Commercial Court) in whichever of the Delhi district commercial courts has territorial jurisdiction, so Saket, Tis Hazari, Karkardooma and the rest. A proposal to raise the district court limit has been under consideration since late 2025. Check the current limit before you file.
A petition filed in the wrong court is usually returned rather than dismissed. But the time it spent there may not be fully protected. You've only got three months to play with, and losing even a few weeks of them to a returned petition is a risk we'd never take for a client.
Filing a Section 34 petition against a DIAC award, step by step
A well-run challenge tends to move in this order. Expect the first few to overlap in the opening weeks.
Fix the limitation date
Start from the date the signed award came in, and count the three months, then the outer 30 days. Did anyone send a Section 33 request, and was it on time? Email both dates to everyone who needs them. Yes, the managing director too.
Get the complete arbitral record
You want everything DIAC holds: pleadings, documents, evidence affidavits, cross-examination transcripts or notes, procedural orders, written submissions, and every mail the Centre sent. Gaps? Ask the Centre for certified copies. The petition lives or dies on this record.
Find the real grounds
Lay the award next to the record. Write down each finding you dispute, then hold each one up against Section 34(2) and 34(2A). Anything that boils down to how the evidence was weighed, cut it. Two or three good grounds will do more for you than twenty thin ones.
Give prior notice under Section 34(5)
The petitioner must notify the other side in advance and file an affidavit confirming it. The Supreme Court has called this requirement directory, so missing it isn't fatal. Judges still look for it. Send it before filing or alongside.
Draft and file the petition
Lay out the facts and the award. Then take each ground in turn, pinned to pages of the record, and close with the reliefs. Annex the award, the arbitration agreement, the parts of the record you rely on, and pay the court fee. The Delhi High Court takes filings electronically. So do the district courts in Delhi.
Ask for a stay if you need one
Your petition doesn't stop enforcement by itself, so move a separate Section 36(3) application along with it, on the same day if you can. Go in expecting to offer a deposit or security.
Finish pleadings and argue
A reply comes from the award holder. Most courts decide on the record and written submissions, after hearing counsel. Cross-examination happens only in rare cases, as Emkay Global v. Girdhar Sondhi (2018) explains.
Act on the judgment
Award set aside? A fresh arbitration is open where the law permits it. Award upheld? You have 60 days to decide on an appeal under Section 37.
Under Section 34(6), the petition is meant to be decided within one year of the Section 34(5) notice. It often isn't. Courts read the provision as directory, and the lists are heavy.
Papers you'll need for a Section 34 petition
The award itself
- The signed DIAC award, with the email, courier receipt or covering letter that shows when it reached you
- Any Section 33 correction request, and the tribunal's order on it
- Fee orders and the final costs assessment, if your grounds touch on them
The arbitration file
- The contract with the arbitration clause, and any other agreement you rely on
- The request for arbitration, statement of claim, defence, counter claim and replies
- Every procedural order, and the tribunal's directions on evidence
- Evidence affidavits, exhibited documents, and transcripts or notes of cross-examination
- Both sides' written submissions, plus any Section 16 or Section 13 applications and the orders on them
Your company's paperwork
- A board resolution or authority letter to file the petition and sign the statement of truth
- The vakalatnama in favour of your advocate
- Details of any bank guarantee or deposit you could offer if you ask for a stay
A Section 34 challenge: stages, timing and costs
| Stage | How long it usually takes | Costs to plan for (lawyer fees aside) |
|---|---|---|
| Reading the award and settling the grounds | The first 2 to 4 weeks after you get it | Certified copies from DIAC, if you need them |
| Drafting and filing the petition | Within three months of receipt (30 more days at the outside) | Court fee under the Delhi court fee law, so check the current schedule. Plus typing, paper books and e-filing charges |
| Stay application under Section 36(3) | Filed with the petition. First orders often come within weeks | Deposit of all or part of the award, or a bank guarantee, if the court orders it |
| Reply and rejoinder | Often 2 to 4 months after notice | Small filing costs |
| Arguments and judgment | Often a year or more in all, depending on the court's list | Costs can be ordered against the losing side under Section 31A |
| Appeal under Section 37 | Within 60 days of the judgment | Court fee for the appeal. Check the current schedule |
Does a Section 34 petition stop enforcement? Stay under Section 36
No. Not on its own. Since the 2015 amendment, Section 36(2) says that just filing a Section 34 petition doesn't make the award unenforceable. You have to apply separately under Section 36(3), and the court can grant a stay on conditions. For a money award, the court must keep in mind the Code of Civil Procedure rules on staying money decrees. That's why the Delhi High Court so often asks for the award amount to be deposited, or a bank guarantee for it.
There's one exception. Under the proviso added in 2021, if the court finds a prima facie case that the arbitration agreement or the award was induced or effected by fraud or corruption, it must stay the award unconditionally until the petition is decided. The allegation has to be specific and backed by material. Saying the process felt unfair won't get you there.
If you hold the award, our guide on enforcing a DIAC award under Section 36 explains what you can do while the challenge is pending.
What the court can do with the award
It can dismiss the petition. It can set the whole award aside, or just the part with the defect. Under Section 34(4), if a party asks, it can also adjourn and give the tribunal a chance to resume the arbitration, or do something else to remove the ground for setting aside, for instance where the reasons in the award are thin. Remission isn't a second hearing on merits. It's a chance to fill a gap.
In Gayatri Balasamy v. ISG Novasoft (2025), a Constitution Bench held that the court also has a limited power to modify an award. It can sever an invalid part, correct clerical, computational or typographical errors, and adjust post-award interest in some cases. It can't rewrite the award on merits. If you're the petitioner and a clean severance is possible, ask for modification as an alternative relief. It spares both sides a fresh arbitration.
Setting the whole award aside doesn't mean you've won the dispute. It just means there's no award any more. The claimant can usually start a fresh arbitration, and Section 43(4) of the Act excludes the time between the start of the arbitration and the court's order when counting limitation for that new case. Keep that in mind before you celebrate.
After the Section 34 judgment: appeal, and then the Supreme Court
An order setting aside an award, or refusing to, can be appealed under Section 37(1)(c). In a commercial dispute in Delhi, the appeal goes to the Commercial Appellate Division of the Delhi High Court. That's so whether the Section 34 order came from a single judge of the High Court or from a district Commercial Court. It has to be filed within 60 days under Section 13 of the Commercial Courts Act. In Government of Maharashtra v. Borse Brothers (2021), the Supreme Court held that delay in these appeals is condoned only by way of exception. Our page on the Commercial Appellate Division of the Delhi High Court explains how these appeals get listed.
The appeal is narrower still. The appellate court checks whether the Section 34 court kept within its limits. It doesn't run its own fresh Section 34 exercise. After that, a special leave petition under Article 136 of the Constitution lies to the Supreme Court, ordinarily within 90 days. The Supreme Court steps into arbitration matters only in a small number of cases.
If you won the award: defending a Section 34 petition
Got a Section 34(5) notice? Do three things. First, check whether the petition was filed in time, counting from the day the petitioner received the award. A limitation objection is often the strongest card an award holder has. Second, go through each ground and mark the ones that are really merits arguments dressed up as legal defects. Third, if the three months have passed and there's no stay, file your own enforcement petition.
When Advocate B.K. Singh acts for an award holder, he usually asks the court at the first hearing to make any stay conditional on full deposit. Otherwise the petitioner buys time at no risk. Delhi courts have often gone along with that for money awards, though every order turns on its facts. And if a fair settlement is on the table, a Section 34 petition can be withdrawn on recorded terms. Our guide on settling a DIAC dispute explains how consent terms are recorded.
How it differs for suppliers, MSMEs, government contractors, lenders and large companies
Suppliers and service providers who lose a DIAC claim usually find their real complaint is about evidence. The tribunal didn't accept their invoices, or didn't believe the delivery challans. Those cases rarely get anywhere under Section 34. Where the tribunal ignored a signed acknowledgment of debt, or a clause that plainly decides the point, there's more room.
MSMEs should check how the arbitration started. If a registered micro or small supplier's dispute went through the MSME Facilitation Council under Section 18 of the MSMED Act, 2006, a buyer challenging that award has to deposit 75 percent of the awarded amount first under Section 19. That rule belongs to the MSMED Act route. It doesn't apply to an ordinary DIAC arbitration under a private clause. Our guide on DIAC versus the MSME Council compares the two.
Government departments and PSUs often lose weeks to internal approvals before a challenge is even drafted. The three months don't wait for the file to move, and the Supreme Court has refused, again and again, to stretch the 30 days for bureaucratic delay. Startups and smaller companies often can't put up a big deposit for a stay. So the decision to challenge has to weigh the cost of security against a realistic view of the chances. Large companies with board approvals and several stakeholders should start the internal process the week the award lands.
If the seat is outside Delhi, or it isn't a DIAC matter at all, general arbitration help for a Section 34 challenge is at arbitrationlawyer.in.
A made-up example: a challenge that worked in part
Nothing here is real. Picture a Noida electronics distributor that loses a DIAC arbitration, seated in New Delhi, to a manufacturer from Okhla. It's ordered to pay Rs 1.6 crore for stock it never paid for, and another Rs 90 lakh as damages for 'loss of reputation'. Claim and counter claim together had crossed Rs 2 crore. So the petition belongs in the Delhi High Court.
The distributor's MD is furious about one witness. He says the tribunal believed the manufacturer's man on whether goods came back, and that's what he wants to fight. His lawyers say no. It's a pure finding of fact. Then, going page by page through the record, they spot a better point. The contract shut out consequential and reputational losses in so many words. And the manufacturer had never pleaded a reputation claim. It surfaced for the first time in written submissions.
They file in week ten after receipt, on two grounds only: that head of damages went beyond the reference, and it contradicted an express clause. The court hears both sides, keeps the Rs 1.6 crore, and severs the Rs 90 lakh. The distributor pays what survived, with interest. Had the petition rested on that witness alone, it would very likely have lost outright.
Mistakes that sink Section 34 petitions
- Counting from the wrong date. People count from the last hearing, or the date printed on the award. Count from when the signed copy reached you, and keep the proof.
- Banking on the 30-day grace period. It's discretionary, it needs a real reason, and a vacation won't stretch it. Aim to file inside three months.
- Dressing up a merits appeal. Courts throw out petitions that only argue facts. Open with your strongest legal ground.
- Forgetting to ask for a stay. With no Section 36(3) application, the award holder can execute while your petition sits pending.
- Filing on a patchy record. If the transcript or an important procedural order is missing, the court simply can't see the defect you're complaining about.
- Crying bias for the first time now. Unless it's Section 12(5) ineligibility, an objection you never raised before the tribunal is usually treated as waived.
What to do this week
Write down the date your company received the signed DIAC award, and work out the three-month date. Put the whole arbitral record in one folder. List every finding you disagree with, and next to each one note whether it's about evidence or about law and procedure. Be honest with yourself on that column. And settle internally who can sign off on a deposit or bank guarantee if you need a stay.
If you hold the award, check the petitioner's filing date the moment notice arrives, and get ready to press for a deposit. Either way, decide early whether to challenge, with a clear view of the grounds and of what security will cost. Our DIAC arbitration lawyer page explains how we handle these matters from award to enforcement.

Frequently asked questions
What's the time limit to challenge a DIAC award under Section 34?
You have three months, counted from the day the signed award reaches you. Show sufficient cause and the court may give you up to 30 days more. That's the absolute limit. Section 5 of the Limitation Act can't be used to stretch it.
Can I file a Section 34 petition after the court vacation if the 30 days expired during the vacation?
No. In January 2025 the Supreme Court held that Section 4 of the Limitation Act only helps if the three-month period itself ends on a day the court is closed. If it's just the extra 30 days that run out during the vacation, filing on reopening day is too late.
Can the court change the amount in a DIAC award?
Only a little. The Constitution Bench in Gayatri Balasamy v. ISG Novasoft (2025) said the court can cut out an invalid part, fix clerical or arithmetical mistakes, and in some cases alter post-award interest. What it can't do is go into the merits and put in a figure of its own.
Does filing a Section 34 petition stop the other side from enforcing the award?
No, filing alone won't hold it back. You need a separate application under Section 36(3), and a stay usually comes with a condition to deposit the award amount or give security. You can get an unconditional stay only on a prima facie case of fraud or corruption.
Where do I file a Section 34 petition against a DIAC award?
In the courts of the seat, which for most DIAC cases means Delhi. Add up the claim and counter claim. Over Rs 2 crore, it's the Delhi High Court's Commercial Division. Below that, the District Judge (Commercial Court). The pecuniary limit may change, so check it before you file.
Can I produce new evidence in a Section 34 petition?
Hardly ever. After the 2019 amendment, Section 34(2)(a) grounds have to be shown from the arbitral tribunal's own record. Extra material gets in only in exceptional cases.
What happens if the court sets aside the DIAC award?
The award is gone, but that doesn't hand victory to either side. The claimant can usually start a fresh arbitration, and Section 43(4) of the Act protects it on limitation. If only part of the award is set aside, the rest still stands.
Can I appeal if my Section 34 petition is dismissed?
Yes, under Section 37 of the Arbitration Act. In a commercial dispute, you have 60 days to file before the Commercial Appellate Division or the Commercial Appellate Court. Courts forgive delay only in exceptional cases.
