"There is no logical rationale for any of the opposition raised by Congress. Congress concern is more of a political red herring than real substance," he said.
Chandrasekhar, who was also the member of the Select Committee which had scrutinised the GST bill, said the state finance ministers in their meeting today have voiced their support for the new indirect tax regime and it was time that Congress listened to the popular opinion.
Chandrasekhar said the Congress' demand of 18 per cent cap in Constitution Amendment bill "will not find any support anywhere" as no government would want to bring in a higher taxation rate.
Congress, which first proposed the constitutional amendment in 2006, is demanding capping the overall rate at 18 per cent and scrapping an additional 1 per cent tax designed to compensate manufacturing-heavy states that fear losing revenue once the measure is implemented.
Also the Congress has been demanding doing away with the power to levy 1 per cent additional tax by the manufacturing states and also an independent dispute settlement mechanism.
The GST bill -- which will help create a single national sales tax to replace several state and central levies -- has already been approved by the Lok Sabha and is pending in the Rajya Sabha where the government doesn't have a majority.
