Imposing a fine of Rs. 50 lakh on former petroleum minister Satish Sharma for arbitrarily allotting petrol pumps, the Supreme Court had said last year that absolute discretion was an anathema to the Constitution and advised the ‘judicious’ use of discretionary powers.
Citing the use of the so-called privileges as “prejudicial to public interest and a breach of trust”, HD Shourie of Common Cause has sought the prime minister’s intervention to “stop this practice of discretionary quota for ministers to present to the public an image of clean functioning of the government.”
In a letter written to the Cabinet Secretary, he has drawn the PM’s attention to the misuse of this privilege by more than a dozen ministers. In the railways, discretionary quota covers platform stalls, passes, tickets and berths on trains. In civil aviation and tourism, the largesse includes free international air tickets, out-of-turn seats and stalls in ITDC hotels.
