It is an interesting situation though, because under the Russian Law proscribing Extremist Groups, the J.W. Org. ticks all the boxes !
So no appeal will work, and the Org. will not take it to a Court like the E.C.H.R, because they would lose, mind you, they have been silly enough to do that sort of thing before.
Crying "Religious Persecution" and "Human Rights" will not wash, no Group has the Right to ignore other Human Rights, such as Freedom of Conscience, and Freedom of Religion, the Right to Family Life etc. Human Rights always come way above Religious Belief and Practice in Law.
Claiming it is their Religious Right to Shun because it is "based on their view of the Bible" has no more strength in Law than something based upon the Quran.
