When a Single Judge sets aside an arbitral award under Section 34 of the Arbitration and Conciliation Act, 1996, what exactly does the Division Bench examine in the appeal under Section 37? In Otsuka Chemical (India) Pvt. Ltd. v. Trans Engineers India Pvt. Ltd., decided on 1 September 2026, the High Court of Delhi (Justices Navin Chawla and Madhu Jain) answered: whether the Section 34 court stayed within its own narrow limits. Finding that it had not — that it had re-read the contract, re-weighed the evidence and even entertained a comparison never pleaded in the arbitration — the Bench allowed the appeal and restored the arbitrator's NIL award rejecting a claim of Rs 28.37 crore.
The commercial background
Otsuka engaged Trans Engineers for a turnkey expansion of its manufacturing capacity — the "Lion Project" — on a lump-sum price of about Rs 71 crore. The perennial turnkey dispute followed: the contractor said the drawings evolved and the work grew; the owner said the evolution was built into the fixed price. The sole arbitrator, after a detailed comparison of the piping and instrumentation diagrams, the offer documents and the purchase orders, found that the contract baseline included the later revisions, that no written instructions for "major" additional work existed as the contract required, and that roughly ninety per cent of the equipment claimed as extra already figured in the contract documents. Result: a NIL award — every claim and counter-claim dismissed.
Round one: the award falls
The Single Judge set the award aside under Section 34(2A) — patent illegality — and Section 34(2)(b)(ii), holding the arbitrator had misconstrued which drawings formed the contractual baseline and had overlooked what the Minutes of Meeting showed about extra payment for later modifications.
Round two: the award returns
The Division Bench reversed. Its analysis is a compact catalogue of what a Section 34 court may not do:
Re-read the purchase orders and minutes to reach an independent view of the contract; re-assessed whether the contractor\'s evidence could quantify the additional work; accepted a comparison document never part of the arbitral record.
Testing the award for perversity, violation of natural justice, conflict with the fundamental policy of Indian law, or illegality going to the root — expressly without reviewing the merits or re-appreciating evidence.
Why the decision matters
NIL awards — where a tribunal dismisses everything — are peculiarly vulnerable to challenge, because the disappointed claimant frames the outcome itself as perverse. This judgment demonstrates that the standard does not soften for such awards. The Bench went further than merely calling the arbitrator\'s view possible: on the record, supported by a detailed comparative exhibit and the claimant\'s own witness\'s admissions, it was the view most consistent with the material. For commercial parties, the message is familiar but sharpened: the arbitration is the trial; the Section 34 petition is not a second innings; and the Section 37 appeal is narrower still.
Build the evidentiary record before the tribunal — comparative charts, contemporaneous instructions, and admissions win turnkey disputes.
Follow the contract\'s variation machinery: claims for extra work without the stipulated written instructions start crippled.
Frame Section 34 challenges within the recognised grounds; an interpretation battle dressed up as "patent illegality" invites reversal under Section 37.
Expect costs discipline: both sides here were left to bear their own costs, but re-litigation strategies increasingly attract adverse costs.
The judgment also reiterates that Explanation 2 to Section 34(2) bars any review on the merits when testing an award against the fundamental policy of Indian law — a point challengers often underestimate.

Frequently Asked Questions
What was the dispute about?
A turnkey construction contract for expanding a chemical plant's capacity. The contractor claimed about Rs 28.37 crore for additional work said to fall outside the baseline drawings; the sole arbitrator held roughly ninety per cent of the "extra" items were already within the contract documents and passed a NIL award, dismissing claims and counter-claims alike.
Why did the Single Judge set the award aside?
The Section 34 court held the arbitrator had misread the contractual framework — treating a later offer and revised drawings as part of the contract — and found the award patently illegal. The Division Bench held this was itself the error: the Single Judge substituted his own interpretation for the arbitrator's plausible one and re-assessed evidence, which Section 34 does not permit.
What is the "possible view" doctrine?
If the arbitrator's construction of the contract is a possible, plausible view — even if not the only or the best one — courts cannot interfere. Interference is reserved for interpretations no reasonable person could adopt, awards that are perverse, or illegality going to the root of the matter.
Can new material be introduced at the Section 34 stage?
No. A challenge under Section 34 is decided on the record before the arbitral tribunal. In this case the respondent's reliance on an equipment list never referred to in the pleadings, contract documents or witness statements was held impermissible — a new factual case cannot be built before the setting-aside court.
