Filing public interest litigation petitions has become an industry and career in itself, Solicitor General Tushar Mehta told the Delhi High Court on Monday while defending the appointment of Rakesh Asthana as the Delhi Police Commissioner. .Mehta said that people who wish to run the government but are unable to get elected, adopt the circuitous route of filing PILs to challenge policy decisions of the elected government. "PIL is an industry. It is a career by itself, which was not envisaged by the Constitution. Some citizens of this country have a desire to run the government. They fulfill their unfulfilled desires by filing such PILs saying 'why this appointment is wrong, why this policy is wrong'. It is for elected government to decide," Mehta argued. The submission was made during the hearing of a PIL petition filed by one Sadre Alam challenging an order passed by the Union Ministry of Home Affairs granting Asthana deputation, extension of service and appointing him as Delhi’s Commissioner of Police just four days before he was slated to retire.The NGO Centre for PIL (CPIL), spearheaded by advocate Prashant Bhushan, is an intervenor in the matter.Time and again Supreme Court has taken view that public interest litigation is not maintainable in service matters, Mehta argued today.He also contended that all the directions contained in the judgment of the Supreme Court in Prakash Singh v. Union of India would not be applicable to Union Territories.Delhi being a Union Territory, the guidelines on appointment of Director General of Police (DGP) will not be applicable as it applies to States, Mehta contended. Rakesh Asthana had also earlier objected to the PIL by questioning CPIL's bona fides.In an affidavit filed before the High Court, he had submitted that NGOs Common Cause and CPIL are engaged in a malicious campaign against him and consistently filing petitions against him in courts.
