Croacia - Unlawful collection of union membership data (2012)

The Croatian Tax Administration, in a circular letter sent on 19 May 2011, requested its employees to fill in forms containing personal data, including their nationality and trade union affiliation. The request was in violation of the Constitution and the Law on Personal Data Protection, as there was no legal document providing for the collection of this kind of data. Following a report filed by the Trade Union of State and Local Government Employees of Croatia, the Croatian Personal Data Protection Agency confirmed the action was unlawful and ordered the Tax Administration to discontinue further collection and processing of such data.
