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 BSNL'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 relevant directives from the Department of Telecommunications and TRAI, service providers must ensure the authenticity of CLI. The judgment clarified that the obligation to transmit authentic CLI is critical for accurate billing and compliance with regulatory standards, thus affirming the Tribunal's ruling in favor of Vodafone.
