According to Sethurathnam Ravi, when the GST was introduced 5 years ago there were a lot of misgivings about how the centre and state governments will work together regarding the tax collection and how the distribution will work. In Sethurathnam Ravi's opinion, compounded with this issue was the platform issue. At the time of the introduction of the GST, there was also the interpretation and the awareness issue from the SSE and it had also created a lot of confusion in that, he says.
