With the ban on 500 and 1,000-rupee notes now more than two weeks old, the government has proposed new rules to tax black money that is being unearthed. The bill was submitted today for parliament's review by Finance Minister Arun Jaitley as the government is being attacked by a united opposition over its sudden withdrawal of 86 per cent of the notes in circulation to check black money and corruption. The move has plunged the country, especially rural India, into a major cash shortage.
