Mr Thakorn Tantasit first submitted the papers to the Office of the Auditor-General at 10 am, saying the move is aimed at assuring to the public that the auction was conducted in a transparent manner.
The key documents include papers about 2.1GHz spectrum bidding, the public hearings which were sanctioned by both the NBTC and the National Telecoms Committee, as well as documents filed by 17 applicants applying for the 3G licence auction on August 27.
"The NBTC is confident that all papers will prove that the bidding process was conducted in a fair and transparent manner and in accordance with international standards," Mr Thakorn said. "They will answer all doubts and criticisms concerning the work of the NBTC," he said.
All documentation will also be submitted to the National Anti-Corruption Commission, the Department of Special Investigation (DSI) and the Office of the Ombudsman for further examination.
In another development, Petchaburi Senator Sumol Sutawiriyawat, president of the Senate Committee on Education, Corruption Investigation and Good Governance, submitted a petition to Mr Panthep Klanarongran, head of the anti-graft agency, seeking an investigation into alleged collusion in the 3G bidding.
Ms Sumol said the petition pointed out that there was no price competition between two companies in the bidding which might be deemed as violating the State Bidding Act 1999.
