The Supervisor

Wojciech Wiewiórowski, European Data Protection Supervisor, was appointed by a joint decision of the European Parliament and the Council. Assigned for a five year term, he took office on 6 December 2019.

The transparent selection procedure which led to his appointment involved the three major EU institutions as follows:

  • A public call for candidates  for the Supervisor posts resulted in the most competent applicants being shortlisted by an inter-institutional selection board;
  • Following interviews with the shortlisted candidates, the selection board presented the European Commission with their recommendations for its review and submission to the European Parliament and the Council.
  • Hearings to evaluate the experiences, skills and independence of the candidates took place in the European Parliament. A joint decision  of the Parliament and Council was reached following their deliberations.
