Because the domestic price of oil was much higher in India when the international price was much lower. At that time the Govt has earned a fortune to take the difference and also the customs & excise duties on oil, which according to the OIl-POOL criteria should be spend on subsidies when the international price went up. But in India that money was taken away from the OIL-POOL and spend on giving tax reductions for big corporations, Chidambaran's own company is one of them. This is day-light robbery.
