Say the ratio out loud before you open Reasoning — recalling it unprompted is exactly what the exam pays for.
Why it matters
It states the evidential half of the finality principle. Sudarshan Trading protects the arbitrator's conclusions; this case protects his assessment of the evidence that leads to them.
Facts
The award was challenged on the footing that the evidence before the arbitrator did not support what he had found, and that the court should look at that evidence again.
Held
The arbitrator is the sole judge of the quality and quantity of the evidence. It is not for the court to re-appreciate the evidence placed before the arbitrator, even if there is a possibility that on the same evidence the court might arrive at a different conclusion.
Reasoning
Step one — weight is for the fact-finder. How much a document proves, and how far a witness is to be believed, are questions of weight. The parties gave those questions to the arbitrator.
Step two — the possibility of a different view is not a defect. Two reasonable people can weigh the same material differently. If that were a ground, no award would be safe.
Step three — the limits. The rule protects the assessment of material that was before the tribunal. It says nothing in favour of an arbitrator who never looked at material documents at all, which is K.P. Poulose.
Exam use
It opens: Can the court re-appreciate the evidence in a petition to set aside an award? — answer no, and cite this case first.
Use it to dispose of a common trap. A problem question often gives you a detailed factual quarrel with the award and invites you to argue it. The right answer refuses the invitation and identifies the ground actually available.
Cite it with Sudarshan Trading and Alopi Parshad as the finality trio, and against K.P. Poulose and Continental Construction as the two recognised inroads.
Bring it up to date with the statutory rule that an award may not be set aside by re-appreciation of evidence, and with the further point that a determination whether the award contravenes the fundamental policy of Indian law does not entail a review of the merits of the dispute.
It does not decide that the court may never look at the record; it may, for the limited purpose of seeing whether the arbitrator had jurisdiction over the claim at all.
