The NACC has pressed charges against the then prime minister and his deputy, plus two high-ranking police officers for alleged malfeasance after the People’s Alliance for Democracy protesters were violently dispersed from outside Parliament in October 2008, resulting in two deaths and more than 300 injured.
Those charged were former prime minister Somchai Wongsawat, General Chavalit Yongchaiyudh, former national police chief Pol General Patcharawat Wongsuwan and ex-Bangkok police chief Pol Lt-General Suchart Muankaew.
The defendants recently submitted additional evidence to the NACC, asking it to withdraw the court case.
NACC secretary-general Sansern Polajiak, who led a committee to consider a petition to drop the suit, said the committee has resolved Tuesday on whether to drop the suit or not.
The decision would be officially endorsed on May 24 before submitting to the NACC on May 26.
