Answer

Yes. The scope of interference under Section 34, and consequently Section 37, of the Arbitration and Conciliation Act, 1996 is limited and does not permit re-appreciation of evidence, but where the award suffers from patent illegality apparent on its face, or where the conclusions reached are not supported by the findings or reasons recorded by the arbitrator, the Court is justified in exercising its jurisdiction under the Act.

Headnote

Arbitration and Conciliation Act, 1996 — s.34 — s.37 — Patent illegality — Award inconsistent with arbitrator's own finding — Arbitration and Conciliation Act, 1996 — s.34 — Scope of interference — Findings not supported by reasons — Held: Interference under Section 34 of the Arbitration and Conciliation Act, 1996, and consequently under Section 37, is confined to patent illegality on the face of the award or conclusions unsupported by the arbitrator's own findings; the Court cannot re-appreciate evidence merely because another view is possible. (¶15) Arbitration and Conciliation Act, 1996 — s.34 — Domestic water use finding — Liability under revised tariff category unexplained — Held further: Where the arbitrator found that 90% of water supplied was for domestic use and only 10% for industrial use, yet held the consumer liable at the "Other Beneficiaries" tariff without explaining why the domestic-use finding became irrelevant after the revised classification, the award's conclusion is not supported by its own findings and the inconsistency goes to the root of the award. (¶14, 16) Arbitration and Conciliation Act, 1996 — s.34 — Clause (C) of award — Patent illegality — Partial setting aside — Held further: Such an unexplained inconsistency amounts to patent illegality apparent on the face of the award, and the order under Section 34 confirming that clause of the award cannot be sustained; Clause (C) of the award is set aside while Clauses (A), (B) and (D) and the order of the Single Judge are confirmed. Appeal partly allowed. (¶17, 18)

In the Court's own words
Paragraph 15It is well settled that the scope of interference under Section 34 of the Arbitration and Conciliation Act, 1996, and consequently under Section 37 of the Act, is very limited. This Court cannot re-appreciate the evidence or substitute its own view for that of the learned Arbitrator merely because another view is possible. At the same time, where the Award suffers from patent illegality appearing on the face of the Award, or where the conclusions reached are not supported by the findings or the reasons recorded by the learned Arbitrator, the Court would be justified in exercising its jurisdiction under the Act.

Also decided in this judgment
Where an arbitrator finds 90% of water supplied was for domestic use, must the award explain why the consumer is still liable at the industrial tariff?
