Setting a 20-day deadline to respond to the notice, the Commission said he has "failed to lodge his account of election expenses in the manner required by the (Representation of the People) Act and rules."
The EC, on the directions of the Supreme Court, had issued a notice to Chavan in May to appear before it in connection with the case of alleged expenses made by him during the 2009 Maharashtra assembly polls which were categorised as "paid news".
The EC order said a candidate who is declared disqualified by the Commission under Section 10 of the RP Act "incurs disqualification for contesting further elections to any House of Parliament or State Legislature for a period of three years "and also for continuing as member of any such House if he is already a sitting member from the date of the order of the Election Commission and not from the date on which he contested the election or was elected at such election."
