B.S.N.L. vs VODAFONE ESSAR GUJARAT LIMITED

The Supreme Court upheld the Telecom Disputes Settlement and Appellate Tribunal's decision to set aside Bharat Sanchar Nigam Limited's demand against Vodafone Essar Gujarat Limited for alleged tampering with Caller Line Identification (CLI). The Court emphasized that under Section 4(1) of the Telegraph Act, 1885, and the directives from the Department of Telecommunications and TRAI, CLI tampering is strictly prohibited. The ruling clarified that the obligations under the Interconnect Agreement must be adhered to, and BSNL's demand was not substantiated by evidence of tampering.
