Over 99 per cent of Idea shareholders voted in favour of the merger at the shareholders' meeting on October 12, 2017, the filing by the Aditya Birla group firm stated.
Both telcos have approached the National Company Law Tribunal (NCLT) seeking its nod. In the next step, they need a final approval from the Department of Telecom.
The meeting of Idea shareholders was convened after directions of the NCLT.
Earlier this year, Vodafone India and Idea Cellular had agreed to merge their operations to create the country's largest telecom operator worth of more than $23 billion with a 35 per cent market share.
The combined entity of Vodafone India and Idea Cellular, which are currently India's number 2 and 3 mobile service operators, respectively, would dislodge Bharti Airtel to counter the fierce price war in the world's second-largest telecom market.
Post completion of the deal, the British firm will own 45.1 per cent stake in the merged entity while the Aditya Birla group, Idea's parent, will have 26 per cent after paying Rs 3,874 crore cash for a 4.9 per cent stake.
The remaining 28.9 per cent will be held by other shareholders.
