Sterlite benefitted from BJP's interpretation of rules?

A Business Standard article has said that Vedanta, which owns Sterlite, got environmental clearance from the Union government to expand the plant to double the capacity without public consultation, courtesy a reinterpretation of the law by the NDA government.

Reports suggest that the NDA government gave its own interpretation to green regulations in December 2014, which helped the plant at Thoothukudi to be constructed without taking the people of the affected area into consultation.
