European Court of Human Rights (ECHR) in Strasbourg issued “an extremely serious warning to Norway”. In an open letter, 170 Norwegian child protection professionals including lawyers and psychologists called Barnevernet a "dysfunctional organisation which makes far-reaching errors of judgement with serious consequences".
And the criticism has extended far beyond Norway. Citizens of the Czech Republic, Russia, Lithuania, India, and Brazil, among other countries, have accused Norway of abusing its authority and ruining families. Even neighbouring Sweden has expressed concern about Barnevernet.
