JUDGMENT : 1. The common issue involved in all these cases is whether the Commissioner is authorised to issue the impugned Circulars fixing the ‘minimum sale price’ for calculating the advance tax realisable under Section 47(16A) of the KVAT Act and if it is within the power and competence of the Commissioner, whether the sale price fixed in respect of ‘Live Chicken’ as involved in W.P.(C) 17708 of 2008 and that of 'Timber' involved in other cases is based on the actual market value and legally reckonable, for quantifying the advance tax, 2. The minimum factual position for adjudication of the cases is as follows: The ‘live chicken’ brought by the petitioner in W.P.(C) 17708 of 2008, stated as purchased for an invoice value of Rs.29/- per Kg from Tamilnadu, was intercepted by the concerned respondents at the Check Post insisting that the goods could be transported only if advance tax was remitted reckoning the value at the rate of Rs.60/- per Kg. as notified by the Commissioner. The goods as well as the vehicle were ordered to be released, pursuant to the interim order passed by this Court on 13.06.2008, on condition that the petitioner remitted advance tax on the price provisionally fixed as Rs.60/- per Kg., making it clear that the payment will be subject to the result of the Writ Petition. 3. In all the other cases, ‘timber’ of different types has been brought into the State as imported from abroad and otherwise. When the vehicles were intercepted at different places/Check Posts insisting for payment of advance tax as contemplated under Section 47(16A) of the Act on the minimum sale price notified by the Commissioner as per Circular No. 28/08 dated 19.06.2008, the power, competence and jurisdiction of the Commissioner to issue such Circular and as to the sustainability of the sale price fixed therein, have been subjected to challenge, seeking for appropriate reliefs. The vehicles and the goods have been released pursuant to the interim orders directing payment of advance tax reckoning the ‘provisional sale price’ as ordered by this Court. 4. The learned Counsel for the petitioner in W.P.(C) 17708 of 2008 submits that the price of ‘Live chicken’ fixed by the Commissioner as per Ext.P4 Circular at Rs.60/- per Kg, is exorbitant and it does not have any nexus with the market price. 4. The learned Counsel for the petitioner in W.P.(C) 17708 of 2008 submits that the price of ‘Live chicken’ fixed by the Commissioner as per Ext.P4 Circular at Rs.60/- per Kg, is exorbitant and it does not have any nexus with the market price. It is also pointed out that the price of ‘live chicken’ varies from place to place and from day to day, as evident from Ext.P2 Notification published by the Tamilnadu Paultry Farmers’ Association in various dailies, which shows that the maximum rate even as on 25.05.2008 was only Rs.30/- per Kg. The price is very much liable to be fluctuated depending upon the ‘demand-supply’ ratio, festival season and adverse calamities including ‘bird flu’ and this being the position, there is absolutely no rationale in fixing the sale price of ‘Live chicken’ as Rs. 60/- per Kg and in realising the advance tax at that rate, much prior to.the taxable event when the sale may take place for a far lesser price, contends the learned Counsel. 5. The learned Counsel for the petitioners in other cases contend that the ‘timber’ being imported is not of standard quality; the prime consumers are persons having lesser income and that the price of such timber even otherwise cannot have a uniform rate, particularly since the price of timber depends upon the quality of timber, size, girth, absence of any holes or hollows, twist/turns, colour and several other vital factors. It is also pointed out that such timber is considered and valued by the authorities of Customs in connection with the imposition of the prescribed duties, based on the ‘invoice value’ and as such, fixation of the sale price by the Commissioner, as per the impugned Circular, ignoring the invoice value and the actual expenses incurred, is thoroughly wrong and illogical. As per the impugned Circular, the Commissioner has obviously adopted a uniform figure without any regard to the nature of timber and the actual market value, which, hence is stated as wrong and unsustainable. 6. Mr. Mayankutty Mather, the learned Counsel for the petitioner in W.P.(C) 17708 of 2008 submits that the live chicken, by virtue of the very nature of the goods/commodity, are highly fragile/perishable in nature and the petitioner will not be in a position to have the goods detained for long, on interception by the departmental authorities. 6.
