Union Of India (Uoi) vs Tata Teleservices (Maharashtra) Ltd.

The Supreme Court examined the appeal under Section 18 of the Telecom Regulatory Authority of India Act, 1997, challenging the TDSAT's decision which rejected the Union of India's plea for set off and counter claim. The Court held that the TDSAT was justified in not accepting the plea of set off due to lack of jurisdiction to entertain the counter claim, affirming the TDSAT's order to refund Rs. 50 crores with interest. The judgment clarified the maintainability of counter claims in proceedings initiated by licensees before the TDSAT.
