Somewhat familiar Helsinki came up so many times that I started searching for Jehovah at http://www.csce.gov/helsinki.cfm I found a CSCE document "Deteriorating Religious Liberties in Europe". This meeting held July 30. 1998 had interesting connection to the Society. Mr Colby May a Senior Counsel in the Office of Governmental Affairs of the American center for Law and Justice was questioned by James Pellecchia from Public Affairs International for Jehovah's Witnesses.
Go and load this pdf-file where on page 19 mr May replies: "On the other hand, I hope that the process of granting to the Watch Tower Society what we call an Intesa, or a sort of concordat in Italy......Intesa is much more than being recognized, it is really entering into cooperative agreement with the government."
To my view religious deterioration in this respect has rather taken place somewhere else.
