The high court said the petition, endorsed by 135 opposition lawmakers, did not merit the judicial intervention.
Pheu Thai MP Chaowarin Latthasaksiri spearheaded the petition after the NACC ruled that Somchai committed a serious disciplinary offence when he was permanent secretary for Justice.
Somchai was found to have made a wrongful decision to condone the waivering of Bt70 million auction fee for a Pathum Thani plot seized via a bankruptcy proceedings.
Chaowarin contended that the NACC had abused power to fault Somchai.
