Sub-Section 7 of Section 31 deals with pre-award and post-award interest.
Hyder Consulting (UK) Limited v. Governor, State of Orissa (2015) 2 SCC 189 overruled State of Haryana v. S.L. Arora, (2010) 3 SCC 690. Justice Sapre was of view, Arbitrator only has discretion to determine rate of post-award interest. Justice Bobde did not expressly discuss ambit of discretion of Arbitrator while granting post-award interest. Therefore, issue was not conclusively decided.
When a discretion has been conferred on Arbitrators in regard to grant of pre-award interest, it would be against grain of statutory interpretation to presuppose legislative intent was to reduce discretionary power of Arbitrators for grant of post-award interest.
Arbitrator must exercise discretionary power to grant post-award interest reasonably and in good faith, taking into account all relevant circumstances.
