The controversial bill against which the Arvind Kejriwal-led Aam Aadmi Party has been protesting, was passed in Rajya Sabha on Wednesday. The opposition protested the legislation, with MPs from parties like the BJD, Samajwadi Party, Congress and the YSR Congress staging a walkout. The opposition had termed the bill 'unconstitutional' and demanded that it be sent to a Select Committee for scrutiny.
