Decision of 22 May 2014 in case C-356/12 Wolfgang Glatzel v. Freiestaat Bayern concerns determining whether there is a conflict between individual provisions of the European Union itself. Formally, this case relates to the provisions of Directive 2006/126/EC on Driving Licenses, as amended by Commission Directive 2009/113/EC, and whether restrictions on the issuance of driving licenses on the basis of visual impairment can be a matter of more basic. provisions, namely of the Charter of Fundamental Rights of the Union (which since Lisbon bind EU law in the category of primary law) are the basis for allegations of discrimination.
