The EC, after framing the charges, also asked the complainants in the case to furnish all their evidence "in the form of affidavits" to the poll-panel by June 4.
The EC's full panel, comprising Chief Election Commissioner (CEC) V S Sampath and Election Commissioners H S Brahma and S N A Zaidi will hold the next hearing in the case on June 9.
Chavan, who recently won Lok Sabha polls from Nanded constituency of Maharashtra, too has been asked to produce evidence "in rebuttal" of the evidence produced by complainants before the hearing.
The apex court had, in its earlier order, given a free hand to the Commission to inquire into complaints of 'paid news' or incorrect expenses against a political leader.
One of the charges framed by the EC in this case states that the hearing would be done to find if the alleged 'paid news' instances were "incurred or authorised by the respondent (Chavan) or by his election agent or by any other person with the consent or knowledge of the respondent or of his election agent"
