"I believe that holding legal proceedings without malice will be a deterrent to troublemakers," Abhisit said on his website.

The Council for Democratic Reform under Constitutional Monarchy (CDRM) should focus on four tasks, he said.

Firstly, he said, the CDRM should expedite graft investigations involving politicians, such as the probe into alleged irregularities in the procurement of CTX bomb-detection equipment. If deemed necessary, suspicious assets should be impounded pending judicial review, he said.

Secondly, Abhisit said, the probe relating to the sale of Shin Corp to Temasek Holdings of Singapore should resume, after the previous government tried to exert influence over it.

The case includes alleged income tax evasion and calls to determine the status of Kularb Kaew Co, seen by some as a foreign nominee.

Thirdly, the CDRM should initiate criminal proceedings relating to violations against the monarchy allegedly committed by the ousted government.

Finally, the authorities should prosecute certain supporters of the previous government

for allegedly instigating violence and disrupting peaceful street protests.

A number of cases of alleged extra-judicial killings during the last government's war on drugs should also be reopened, the democrat leader said.
