The Election Commission of India's decisive blow to the Arvind Kejriwal-led Aam Aadmi Party government in Delhi, disqualifying 20 of its legislators as unfit to hold their posts under the office of profit rules, has virtually set the stage for a mini-election that will see the AAP, the Bharatiya Janata Party and the Congress vie for their in the 70-member-strong Delhi legislative assembly. While the final decision will rest with the President of India, to whom the EC has sent the recommendation to for his assent, there is no immediate threat to the AAP government in Delhi. The AAP, which won the 2015 Delhi Assembly election decisively, winning 66 seats, reducing the BJP to 4 and the Congress to an empty bag, remains in a solid position as far as the number of seats is concerned. While we are yet to hear from the President on the EC's recommendations, we bring you a breakdown of the build-up to this decision and understand its likely impact. What is the Office of Profit case against AAP? Prashant Patel, a Delhi lawyer had moved a petition against 21 AAP MLAs, appointed parliamentary secretaries to ministers for \u201csmooth functioning\u201d of the government, for holding offices of profit. Of these 21 legislators, one MLA, Jarnail Singh, resigned in January to contest the Punjab elections. The AAP, however, has said in its defence that these parliamentary secretaries were not given any perks and hence did not qualify as under the definition of office of profit. Notably, former Congress president Sonia Gandhi had in March 2006 resigned from parliament on moral grounds when similar charges were levelled against her by the opposition.
