Manmohan Singh today prevailed upon the Congress not to try to score political points by pressing amendments to the GST bills in the Rajya Sabha, facilitating their return to the Lok Sabha unchanged.
The four Bills are the Central Goods and Services Tax Bill, 2017, the Integrated Goods and Services Tax Bill, 2017, the Goods and Services Tax (Compensation to States) Bill, 2017 and the Union Territory Goods and Services Tax Bill, 2017.
Speaking with reporters after parliament passed the bills, Finance Minister Arun Jaitley said it was a "historic day".
Jaitley added that the government was still looking at July 1 as the roll out date for the new indirect tax regime.
In the backdrop of a reconciliatory mood, Rajya Sabha members showed consensus that the new indirect tax is the biggest reform since Independence and is the need of the hour.
The four GST Bills were passed after an eight-hour marathon debate in the Lower House. "It will become hard to implement", Jaitley said but O'Brien did not relent.
One more piece of legislation, the State GST Bill, will have to be passed by the legislative assemblies of States and Union Territories with legislature.
"If we are looking at one nation, one tax, than these issues should be looked into", he said.
