The Upper Tribunal has referred a case regarding whether contract bridge is considered a sport for VAT purposes to the Court of Justice of the European Union. The Tribunal is seeking clarification on the definition of "sport" based on arguments that bridge improves mental well-being versus the definition in the European Sports Charter requiring physical activity. In a separate case, the Court of Justice ruled that "flash" sales of fuel can qualify for VAT exemption if delivered directly to ships. This may have implications for intermediaries in supply chains that do not take ownership of goods. The European Commission also reported that the EU VAT gap, the difference between expected and collected VAT, was €168 billion in 2013, with the UK gap estimated at €15.4 billion
