Trilegal has acted for Idea Cellular before the Competition Commission of India (CCI), which approved the telecom company’s $23 billion deal to merge with Vodafone India, which was represented by Shardul Amarchand Mangaldas & Co. 

The transaction is said to be largest by value in the Indian M&A history. 

Vodafone India and Idea agreed to combine operations in March, and the merger expected to be finalised in 2018. The deal, which will create the country's biggest telecom player shows how India's mobile industry is being transformed by the launch of Reliance Jio Infocomm's 4G mobile broadband network last year, reported Reuters. 

The SAM team was led by partner Shweta Shroff Chopra, while partner Nisha Kaur Uberoi headed Trilegal’s team.
