The European Commission (EC) has expressed concern with the Hungarian government over whether changes to its constitution comply with EU law. Olivier Bailly, a Commission spokesman, said that the Commission is currently studying 30 laws, which were adopted as part of the revised constitution. Viviane Reding, the European commissioner for justice, fundamental rights and citizenship, is particularly concerned with whether the laws guaranteed the independence of national judges and the national supervisor on data protection. Reding wrote to Hungarian ministers in December “spelling out her doubts” over the laws.
