The payment terms are so staggered that the concessionaire is held accountable for the repair and maintenance of the highway as well. The contract needs to be looked at holistically based on the services to be performed by the concessionaire and cannot be artificially split into two separate contracts for construction and operation and maintenance, based on the payment terms. The concessionaire is bound contractually to complete not only the construction of the highway but also to operate and maintain the same.

specified periods, or on completion of an event, as specified in the contract. The same appears to be covered under the ‘Continuous supply of services’ as defined under section 2(33) of the CGST Act.
