In 2007, a case (Janowiec and Others v. Russia) was brought in front of the European Court of Human Rights, with the families of several victimes claiming that Russia violated the European Convention on Human Rights by withholding documents from the public. The declared admissible two complaints from relatives of the massacre victims against Russia regarding adequacy of the official investigation. In a ruling on 16 April 2012, the court found Russia had violated the rights of victims' relatives by not providing them with sufficient information about the investigation and described the massacre as a "war crime". But it also refused to judge the effectiveness of the Soviet Russian investigation because the related events took place before Russia ratified the Human Rights Convention in 1998. The plaintiffs filed an appeal but a 21 October 2013 ruling essentially reaffirmed the prior one, claiming that the matter is outside the court's competence, and only rebuking the Russian side for its failure to substantiate adequately why some critical information remained classified.
