The CBI on Friday told a Delhi court that there were contradictions in the Telecom Regulatory Authority of India's stance, including the one according to which it says it did not consider the telecom services and spectrum as a source of revenue. The CBI said this while submitting the TRAI report to the court in response to the demand by the former Telecom Minister, Mr A. Raja, and other accused in the case to bring it on the court's record. The agency said it is still awaiting clarification from TRAI on various issues related to 2G spectrum allocation. The investigating agency said the August 20 letter, written by the regulator to it, was not in consonance with the recommendations of the expert committee which was constituted to determine annual value of the spectrum.
