States are under fresh pressure to agree to rationalisation of GST rates by reworking slabs and raising the levy on garments and footwear as the Centre has got legal opinion to back its claim that it does not have a liability of paying compensation to the states that fail to increase collections by 14%.While officials at the Centre and the states have maintained this argument for months, last winter, state finance ministers had opposed any attempt to rationalise the levies at a meeting of the GST Council. Armed with the attorney general’s opinion, the Centre will once again lob the ball back in the GST Council’ court. The all-powerful panel comprising state and Union finance ministers is scheduled to meet shortly to discuss the issue of compensation, with opposition-ruled states such as Kerala and West Bengal pressing the Centre to bear the burden.
