In the November 2007 issue of European Taxation, an article considered the decision of the Netherlands Supreme Court of 22 December 2006 to request a preliminary ruling from the European Court of Justice (ECJ) in the case of Mr Renneberg. The author of this article now critically examines the ECJ's decision of 16 October 2008 in Renneberg. Although the ECJ's decision is understandable in the light of previous decisions, the author disagrees with it in this case. The author is of the opinion that the decision of the ECJ in the Renneberg case is erroneous and that the Court has expanded its Schumacker doctrine, which is based on a just EU "principle", i.e. in extreme situations, the source Member State must treat a non-resident as a resident, to situations for which it is not justifiable.
