In the same judgement the ECHR reviewed the judgements of several international and municipal courts judgements. It noted that International Criminal Tribunal for the Former Yugoslavia and the International Court of Justice had agreed with the narrow interpretation, that biological-physical destruction was necessary for an act to qualify as genocide. The ECHR also noted that at the time of its judgement, apart from courts in Germany which had taken a broad view, that there had been few cases of genocide under other Convention States municipal laws and that "There are no reported cases in which the courts of these States have defined the type of group destruction the perpetrator must have intended in order to be found guilty of genocide".
