NDTV has learnt that as the minister in charge, Dr Singh has now sought legal clarifications from the Ministry of External Affairs and the Law Ministry on whether international obligations can override India's nuclear liability bill.
Citing his concerns, Dr Singh has pointed there will be demands for the same treatment by the Americans and the French companies on the grounds of a level playing field.
The Tamil Nadu government has given its no objection from its pollution control board to the Kudankulam nuclear project but there is fresh hurdles for the phase 3 and 4 of the project. The Cabinet Committee on Security (CCS) is expected to clear the next phase of the project.
The Department of Atomic Energy, meanwhile, argues that Nuclear Power Corporation does not need to exercise the right to recourse as there is a provision in the international agreement and there is no such provision with the American and the French governments.
The Russians are keen that the right to recourse does not apply for its project and have brought this up during their bilateral meetings with prime minister Manmohan Singh.
