The OSCE organisation has a permanent council in Vienna, Austria, Europe
A simple search for jehovah in the osce homepage leads you for example to all the interesting articles by the europan association of JW concerning religious freedom in russia or ukraine. Of course JW are active here.
In Austria - my country - Jehovahs witnesses are one of the 16 state approved churches and religious societies, The state has very well a right to look into a religion. They have same duties and rights like islam, catolic, protestant or mormon church. They could offer religious education in school classes, or demand monthly contributions. In Austria obviously as JW you are becoming a "real member " of an state approved institution. Austria lateley changed the religious law for Islam, to prevent financing of terrorism and djihad extremist ideology, via financing of education, training of extremist Imam in Vienna. Before the acceptance of JW as approved religious society it is has been very well checked, wether the teachings are acceptable for the public welfare or not.
BTW, GB member Gerrit Lösch is Austrian citizen.
