When the matter came up before Justice R Subbaiah, Advocate General A L Somayaji, who appeared on behalf of the state, submitted that the appointments had already been made.
The judge then directed the AG to file the counter by March 4 and issued notice to the advocates and the public service commission.
Appearing on behalf of Elangovan, a former MP, senior counsel P Wilson argued that the constitutional trust that was reposed on the Chief Secretary "has been breached for political reasons".
The advocate, who were appointed as members of TNPSC, have no experience in administration, the petitioner claimed.
Elangovan sought declaration of the appointments as illegal, ultra vires and violative of the Constitution and various directives of the Supreme Court.
