The Higher Administrative Court of Hamburg has rejected an appeal brought by the Hamburg Data Protection Commissioner against the Court’s ruling in March 2016 to require German Facebook users to use their real names. The Court had held that the German right to use a pseudonym was not applicable since the German subsidiary  of Facebook was operating mainly in the advertising industry. The Court held that EU law is indeterminate on the question of whether national data protection authorities can take action against a company based in another member state on the basis of that competent authority’s national law.
