|Cheaper beer but is it legal?|
Under EU law you can not discriminate against another state's products. As the UK does not produce (much) wine the EU could argue that this breaks EU law. They have done it once before.
In the 1983 case "European Communities v United Kingdom of Great Britain and Northern Ireland. - Tax arrangements applying to wine. - Case 170/78." The Court found that:
Before people get their spirits up (pun intended) we just hope the Treasury's lawyers were consulted.... And if it is legal then there is nothing stopping France putting up its tax on beer...ON THOSE GROUNDS ,THE COURTHEREBY :1 . DECLARES THAT , BY LEVYING EXCISE DUTY ON STILL LIGHT WINES MADE FROM FRESH GRAPES AT A HIGHER RATE , IN RELATIVE TERMS , THAN ON BEER , THE UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND HAS FAILED TO FULFIL ITS OBLIGATIONS UNDER THE SECOND PARAGRAPH OF ARTICLE 95 OF THE EEC TREATY .
