Does Directive 219/112/EC, and in particular Articles 63, 167, 168, 178, 179, 180, 182 and 219 thereof, and the principle of neutrality, preclude legislation which has the result that, in circumstances where the seller of the goods, liable for VAT, (i) was subject to a tax inspection which found that the VAT rate that he applied in a given situation was less than the due rate, (ii) paid to the State the additional tax and (iii) seeks to obtain the respective payment from the purchaser, also liable for VAT, the time period for the latter to be able to deduct that additional tax is calculated from the date of issue of the initial invoices and not from the date of issue or receipt of the rectifying documents?
