GST Implications on Arbitration Awards: Distinguishing Price Revisions from Compensatory Damages under Section 142(2)(a)

The transition from the pre-GST regime (Service Tax, VAT, Excise) to the Goods and Services Tax (GST) framework continues to present complex legal interpretational challenges, particularly concerning long-term infrastructure contracts. A recurring area of litigation involves the taxability of arbitration awards and settlement amounts received in the post-GST era for works completed prior to July 2017.

A recent ruling by the West Bengal Authority for Advance Ruling (AAR) in the case of In re Karam Chand Thapar & Bros (Coal Sales) Limited provides critical clarity on this subject. The ruling delineates the fine line between "upward price revision," which is taxable, and "compensatory damages," which may remain outside the GST net.

Factual Matrix of the Case

The factual backdrop involves the assessee, Karam Chand Thapar & Bros (Coal Sales) Limited, who entered into three distinct contracts in January 1996 with THDC India Limited. These contracts pertained to the execution of civil works for the Tehri Hydro Power Plant, segregated into Packages I, II, and III.

The timeline of events is significant for the legal interpretation:

  1. Execution Phase: The works were executed and completed entirely during the pre-GST regime.
  2. Billing: Final bills were raised by the assessee between 2010 and 2011.
  3. The Dispute: During the project, significant disputes emerged regarding extra expenditures, price adjustments, rebates, and additional works.
  4. Arbitration: Following a four-tier dispute resolution mechanism and subsequent intervention by the Supreme Court, an Arbitral Tribunal was constituted in 2015.
  5. The Award: The Tribunal passed awards in favor of the assessee on November 1, 2023.
  6. Settlement: After THDC India Limited challenged the award under Section 34 of the Arbitration and Conciliation Act, 1996, the parties entered conciliation. A settlement agreement was finalized on October 24, 2024, resulting in a payment of ₹94.56 crore to the assessee.

The core dilemma for the assessee was determining the GST liability on this receipt. Specifically, did these funds represent "liquidated damages" (non-taxable) or "consideration for supply" (taxable)?

To understand the AAR's decision, one must examine the transitional provisions of the CGST Act, 2017.
