This year's Avoir Fiscal Anniversary Conference, scheduled to take place on Friday, 27 January 2012 at the Institute of Advanced Legal Studies of the University of London, focuses on the application of EU Law on National Tax Systems. 
My presentation on "The application of EU Law on the Greek tax regime: two recent cases" focused on the main issues of two cases that were delivered in 2011, namely:
(1) the decision of the Court of Justice of the EU in the case C-155/09 on the exemption of first residential real property and
(2) the decision of the Commission C 16/2010 regarding the aid to certain Greek casinos.      

My paper on "The distortion of competition through discriminatory tax treatment and its consequences. How a cheap entrance ticket to the Casino can be very expensive" was published in the November 2011 issue of Business and Company Law Review (in Greek). 
The paper deals with the recently published decision of the European Commission C 16/2010 in which it was concluded that the cheaper entrance fee established by law for certain Greek Casinos constitutes unlawful fiscal state aid. 
The paper presents the key points of the Commission decision and analyzes certain aspects of fiscal state aids as well as the responsibilities of enterprises receiving unlawful state aid and of their legal and tax advisors.
