The Democrat petition singled out the top two officials of the Department of Special Investigation, director-general Tarit Pengdith and his deputy Pravesana Mulpramook, for lapse of duty in their enforcement of the lese majeste law.
Suthep said he wanted the NACC to probe the two officials on two separate cases.
In the first case, Tarit had made several comments in the media about the existence of a conspiracy to topple the monarchy. But after a change of government, he abruptly submitted the DSI report to the public prosecutors recommending the charges be dropped.
Suthep said he suspected Tarit and Pravesana had drawn an unlawful conclusion because the two did not make reasonable efforts to collect evidence.
In the second case, Tarit spearheaded the DSI investigation on royal insult involving red-shirt leader Jatuporn Promphan in connection with his rally speech in April 2011.
The investigative work had progressed to the point the Criminal Court agreed to revoke Jatuporn’s bail last May.
The bail was previously granted to Jatuporn after terrorism charges were laid in connection with the 2010 political mayhem.
Due to suspicion of an alleged royal insult, the DSI managed to hold Jatuporn in the remand cell until his release last August following the general election in which he won a House seat.
Suthep said Tarit made an about-turn on May 10 to drop the royal insult charges against Jatuporn. He added that the DSI chief appeared to have made two conflicting conclusions on
the Jatuporn case, one of which was definitely wrongful because an individual suspect could not be guilty and not guilty in the same case.
