May be I did not understand the GST proposal well. I do not understand how the goods movement across some state should enable it to charge 1% of tax on the goods moving through it and claim it, may be in due course? Such states did not sin in production.They did not sin in consumption as well. Without sinning either way, how can they claim a percentage of the tax collected? Of course they permit goods travel across their state when that becomes necessary for another statewallah to get it! To this advantage, their own dwellers also are eligible when a need arise for themselves. Hence transportation usage can be bartered at least in theory between states.Ideally the producing state should get the tax benefit-for production is a difficult art- to manage without polluting the production location.In fact , a certain percentage of GST should be reserved for  environmental improvement of the production location.There is no need to wait for an environmental tragedy to stage, for acting against it. And as an initiator of demand the consuming state also
has a good claim,especially it will suffer cleaning the packaging etc.The claim of the Central Government must be for maintenance and up-gradation of overall trading and other facilities useful and necessary for all states! I would like to hear expert views....
