It was not until this week that an amendment to a Russian law on burying and funeral arrangements came into a light. According to Novaya Gazeta, Putin signed the amendment suggested by Duma one month after the Dubrovka hostage taking. The amendment prohibits from returning the bodies of those who were killed "as a result of interception of their terrorist activity". The location of the burials is also a secret.
According to Alexander Podrabinek, such amendment makes it impossible to find the exact cause of death and avoid falsification.
On June 28, 2007 Russian Constitutional Court confirmed the amendment.
It seems that the only governing body in Russia is the European Court of Human Rights.
