How to complain
If you believe that your personal data has been processed unlawfully during the performance of investigative or operational actions and that your human right to private life has been violated, you have the right to complain.
Secret surveillance of your communications and activities, as well as the search and seizure of your electronic devices and data indisputably limit the right to control the use of your personal data and thus the enjoyment of your right to private life. If you believe that the investigative and operational activities taken are unlawful and/or disproportionate, you can challenge the decisions and actions taken by the public authorities.
