The Constitutional Court of the Slovak Republic declared mass surveillance of citizens unconstitutional

Under the provisions now invalid, electronic communications providers were required to store information about traffic and calls for six or twelve months, depending on the type of data. Included are data on failed phone calls. The police could receive the necessary information without notifying the citizen.
Every citizen of Slovakia has been closely monitored regardless of honesty or innocence. One of the initiators of the lawsuit in terms of the constitution noted that these laws led to years of persistent privacy violations.
In April 2014, the European Court of Justice recognized the invalidity of the directive on the storage of data and negotiations of subscribers, requiring telecom operators to store data on negotiations of EU citizens for two years. After this decision, the mass collection, storage and processing of data on citizens of Slovakia were suspended, and now banned.
