The Commission against Corruption did not investigate Frank Sammut in 2003, a statement from the Office of the Prime Minister (OPM) read.

In 1993, an anonymous accusation was made against Sammut regarding the purchase of oil. This was investigated by the Commission which was presided over by ex-Judge Victor Borg Costanzi. The investigation concluded that it found no evidence to prove that what was in the letter was true, the OPM argued. The report was presented to Parliament by then Minister for Justice Joe Fenech on July 18 1994.

In addition, two reports were made in 1999 relating to a tender with connections to the Mediterranean Offshore Bunkering Co Ltd (MOBC). These reports were investigated by the Commission, which was then presided over by ex-Judge Albert Manche. In both cases it was concluded that the allegation was unfounded and the two reports were made public in Parliament by the then Minister for Justice Austin Gatt, The OPM concluded.
