The European Court of Human Rights has ruled, unanimously, that Hungary had violated Article 8 (respect for private and family life,  the home and correspondence) and Article 13 (right to an effective remedy) of the European Convention on Human Rights through its legislation on secret anti-terrorist surveillance introduced in 2011. Even though the Court conceded that surveillance technologies were a consequence of current terrorism, it held that Hungarian legislation did not provide sufficient safeguards against abuse.
