The party said the decision was akin to then Sheila Dixit government's move to give provisional certificates and then forget about such colonies.
"Wid an eye on elections, Cabinet has decided to regularise unauthorised colonies of Delhi "from 1.6.2015". This is nothing but a pre-poll gimmick, akin to Sheila's provisional certificates. Congress forgot these colonies after elections.
"People know that U-turn BJP govt will also forget them after elections. People have faith only in AAP becoz AAP does what it says," Kejriwal tweeted.
"The government is trying to fool 60 lakh residents. With this kind of order, the residences cannot be registered nor can they apply for any loan.
"After this decision, the municipal corporations can neither build roads nor can they lay sewer lines. AAP will immediately bring a law on this," Sisodia tweeted.
In a decision that will benefit about 60 lakh people in poll-bound Delhi, Union Cabinet today approved an Ordinance to regularise 895 unauthorised colonies which have come up till June 1 this year.
