Lawyer Bundith Siriphan represented the plaintiffs in submitting the lawsuit on Wednesday, charging DSI Director General Tarit Pengdith and four other officials with breaching Articles 157 and 200 of the Criminal Code.
Mr Tarit and his DSI associates were accused of unlawfully charging Mr Abhisit and Mr Suthep with initiating the murders of people during the political disorders when they, in fact, carried out their duty under the emergency decree.
Mr Abhisit said he would wait to see if the court will accept the case for trial while he and the Democrat MP from Surat Thani are ready to testify.
The former prime minister said he is not worried about possible interference by the United Front for Democracy against Dictatorship (the Red Shirts) during the Democrat Party’s political rally in the northeastern province of Nakhon Ratchasima this Saturday.
