On 27 September the hearing was held at the European Court of Human Rights, following the application against Poland lodged by activists from Poland’s Panoptykon Foundation and Helsinki Foundation for Human Rights, joined by a human rights attorney. The group alleges that the state violated their right to privacy by allowing the intelligence agencies to act beyond scrutiny. Their case has been supported by the United Nations special rapporteur, Polish Ombudsman and the European Criminal Bar Association, attending the Strasbourg hearing as well.

The European Court of Human Rights demanded the Polish government to provide an explanation in the case of surveillance by intelligence agencies.
