Greece has technically missed the two-month deadline - which the EU Commission set for the government in Athens on December 21st 2015 - for a uniform and unconditional confirmation that the Greek government indeed intends to change several parts of the lucrative taxation for the country's large shipping industry.

If the answer is different, Greece could be close to a court case at the Court of Justice of the European Union (CJEU) in Luxembourg, as large parts of the country's tonnage taxation, according to the Commission, constitute illegal state aid.
