After coming to power in 2015, the AAP government in Delhi had passed an amendment to the Delhi Members of Legislative Act, 1997, and had asked the EC to exempt the parliament secretaries from the definition of office of profit.
Earlier Supreme Court rulling had directed the state government over the appointment of Parliamentary Secretary on the ground that that such appointment is illeglal as it amount to the holding of office of profit. "AAP has been helped by BJP & EC by delaying the decision for over 3 weeks".

MLAs who are stranded in the office of profit has finally been canceled.
Sujit Dey, counsel for the 10 legislators, said the issue of disqualification has become "infructuous" since the post of Parliamentary Secretary itself had ceased to exist, and all parliamentary secretaries had immediately resigned after the High Court verdict.
The disqualification will not put into jeopardy Kejriwal's government because of its huge majority in the Delhi assembly. Alka Lamba, also one of the 20 MLAs to be disqualified, described the decision of the President as "painful" and said that the President should have heard them out once before arriving to any conclusion.
The complaint was against 21 MLAs out of which one MLA Jarnail Singh had resigned in January previous year for contesting Punjab Assembly Polls.
