  • Nature of Proceeding: Two arbitration petitions (No. 1158 of 2014 and No. 256 of 2015) filed under Section 34 of the Arbitration and Conciliation Act, 1996, challenging arbitral awards dated 24 April 2014 and 10 October 2014.
  • Contract Background: MCGM invited a tender for planning, designing, and constructing 20 community toilet blocks (each 20‑seat capacity) in slums of R‑Central Ward, Mumbai. The work was split into two phases – community‑based sanitation awareness (Phase 1) and construction (Phase 2).

  • Key Contract Clauses Cited: Site investigation (cl. 14), intended completion date (cl. 17), engineer’s approval (cl. 18), possession of site (cl. 21), variations (cl. 39‑40), retention (cl. 48), and compensation events (cl. 44).
  • Arbitrator’s Findings: The Tribunal awarded amounts for several claims, reduced others, and rejected some. Total award: Rs 37,69,666.07 plus 12 % interest from 28 Feb 2008 to 24 Apr 2014.

  • Idle Labour Compensation Breakdown: Rs 19,78,250 (labour), Rs 9,60,350 (staff), Rs 27,25,700 (machinery), Rs 20,43,108 (establishment). Percentages of idle charges relative to work value ranged from 4.25 % to 61.8 % across four contract periods.
  • Legal Reasoning: The Court reiterated the limited scope of interference under Section 34, citing Hindustan Construction Co. Ltd. v. NHAI and PSA Sical Terminals Pvt. Ltd. v. V.O. Chidambaranar Port Trust. It held that arbitral findings on technical matters are not subject to appellate re‑appraisal unless there is patent illegality or violation of public policy.
  • Supreme Court Precedents: The judgment referenced Voestalpine Schienen GmbH v. DMRC and Delhi Airport Metro Express (P) Ltd. v. DMRC on the deference owed to technical arbitrators, and Associate Builders v. DDA on the public‑policy test.
  • Petitioner’s Contentions: MCGM argued that extensions were granted without liquidated damages, that rate‑revision claims were barred by a prior undertaking to work at original rates, and that many claims lacked contractual basis.
  • Court’s Rebuttal: The Court found that MCGM failed to hand over sites as per Clause 21, causing compensation events; the Tribunal correctly applied contract provisions and awarded reasonable amounts.

Final Outcome

  • Both Arbitration Petitions (Nos. 1158 of 2014 and 256 of 2015) are dismissed.
  • The accompanying Notice of Motion is also disposed of.
  • The petitioner's prayer for a stay of the award is rejected.
  • The arbitral awards, including the total sum of Rs 37,69,666.07 and accrued interest, remain in force.
