The prosecutor for the Siberian city of Tomsk has twice failed in a Russian lower court to have the Bhagavad Gita, and/or commentary accompanying a translation of it, deemed "extremist literature". The prosecutor accused the scriptures (held sacred by Hindus) as inciting "social hatred" and "violence against non-believers." The accompanying commentary was penned by the founder for the International Society for Krishna Consciousness (ISKON), commonly known as the Hare Krishnas. An appeal to a higher court is possible.
