In an April 2017 judgement that supported the prosecutors, the court deemed that Russia's failure to act on "sufficient" evidence about a likely attack on a North Ossetia school had violated the "right to life" guaranteed by the European Convention on Human Rights. The court stated the error was made worse by the Russian use of "indiscriminate force." Result were published in April 2017, and found that Russian actions in using tank cannons, flame-throwers and grenade launchers "contributed to the casualties among the hostages", and had "not been compatible with the requirement under Article 2 that lethal force be used 'no more than absolutely necessary." The report also said that "The authorities had been in possession of sufficiently specific information of a planned terrorist attack in the area, linked to an educational institution," "nevertheless, not enough had been done to disrupt the terrorists meeting and preparing," or to warn schools or the public.
