The Government will now be tested for its sincerity in implementing the order cancelling all allotments following The Indian Express expose of the petrol-pump scam as it begins to counter a slew of stay orders from High Courts across the country. It took the first step today—when the High Courts of Delhi, Rajasthan, Guwahati and Madhya Pradesh passed stay orders—directing the Solicitor General to approach the Supreme Court tomorrow asking for the transfer of all writ petitions to the apex court for a common hearing. Whatever its legal defence, the Government will be hampered by its own refusal to acknowledge any wrongdoing in the allotments it has decided to cancel. The Government will also be hard pressed to counter the doctrine of estoppel being cited by petitioners: Since they claim to have invested about Rs 25-30 lakhs to set up petrol pumps or gas agencies, the doctrine of estoppel bars the Government from cancelling the allotments at this stage without giving any chance to the petitioners to defend their case.
