Justice M Venugopal said petitioner B Selvam's charges were vague in nature and he had not made out a prima facie case against the minister.
The petitioner's counsel produced a few transfer orders issued by Tamil Nadu State Marketing Corporation (TASMAC) and claimed that most of them had reference to recommendations made either by the Minister or his Personal Assistant.
Though a complaint was given to the Directorate of Vigilance and Anti-Corruption, it had not been registered, Selvam said.
But in the case of the Minister, no such preliminary enquiry was held, he alleged.
