Existing law allows EC to ban them just 48 hours prior to voting.
The poll panel has proposed that there should be a prohibition on publication and broadcast of the results of opinion polls starting from the date of notification of elections till the completion of the last phase of polls to the Lok Sabha and state assemblies.
The view of Attorney General G E Vahanvati was sought on the EC's proposal after the poll body proposed the ban. His opinion has since been forwarded to the EC which will take a final call on the issue.
He said "one must also take into consideration the view of the political parties at the meeting held on April 6, 2004 and the unanimous view expressed therein."
To support his view to ban opinion polls, he also pointed that the amendments incorporating restrictions in relation to exit polls have been in force for over three years "and there does not appear to be a challenge to this."
Delhi, Rajasthan, Madhya Pradesh and Chhattisgarh are among the states going for assembly polls later this year.
