New Delhi, May 23: Terming it unconstitutional, Congress leader P. Chidambaram on Wednesday said the government’s proposal of allocating cadres and services to candidates selected under civil service examinations only after completion of foundation course will compromise the anonymity and objectivity associated with the exam. It will lead to the “preference” of the executive government playing a role in the selection process. “First, the proposed change appears to be unconstitutional as it is violative of Article 320. The selection for ‘appointment’ to the service, now done solely by the UPSC, will be affected by the foundation course marks given by the executive government,” Chidambaram wrote in a blog post. “I doubt if the proposed change can be implemented without amending Article 320,” he said. The Congress leader said the move will “greatly” affect the anonymity and objectivity of the selection process.
