CENVAT credit restriction: limited credit available for specified services when service tax is paid after availing input credit. The amendment inserts a sub-rule in the Works Contract composition rules restricting CENVAT credit for specified taxable services: credit is available only to a limited extent when service tax is paid on the full value of the service after availing CENVAT credit on inputs. The provision modifies rule 3 of the principal rules and takes effect upon publication in the Official Gazette, changing credit entitlement under the composition scheme where input credit has been utilized.
