Contractors could not factor an unenforceable cess into bid prices, so later implementation may qualify as subsequent legislation under the contract. Retrospective cess adjustment from an arbitral award was impermissible where the contract ended before the regime became operative and the issue was not raised in arbitration. Under the foreign-currency price-adjustment formula, only 85% of the Euro component was adjustable; a further 85% adjustment would create an impermissible compounded adjustment. Plausible arbitral interpretations remain protected under limited arbitral review. en-us Tue, 20 Jan 2026 00:00:00 +0530 Tue, 28 Jul 2026 19:00:22 +0530 TaxTMI RSS Generator https://www.taxtmi.com/caselaws?id=470464 Building-workers welfare cess becomes leviable and collectible only after constitution of the relevant Welfare Board and operationalisation of statutory machinery for levy, collection, deposit and utilisation.
