The Centre told Supreme Court that it is bound by its ruling on allocation of 2G spectrum through auction but felt a similar route for other natural resources will hamper FDI and other investments in the country.

It said the Presidential reference was only pertaining to adoption of the process for allocation of other natural resources. Attorney General G E Vahanvati submitted this before a five-judge Constitution Bench headed by Chief Justice S H Kapadia yesterday.

The Attorney General termed as incorrect the contention that the present reference seeks to overturn or overrule the judgment dated February 2.

The Attorney General rejected the allegation that the Presidential reference is malafide and deserved to be returned.
