The government notification on demonetisation was "unlawful" and the notes ban process could not have been initiated by the Centre, justice BV Nagarathna said today in her strong dissent after a Supreme Court Constitution bench, with 4:1 majority, upheld the notes ban decision by the Narendra Modi-led Centre. She called the November 8, 2016 notification of the Centre "unlawful" and argued that as per the Reserve Bank of India Act, RBI should have independently recommended demonetisation and not through the advice of the government.
