group's activities within Germany. The results of this investigation indicated that at the time of publication, Scientology's main sources of revenue ("Haupteinnahmequellen der SO") were from course offerings and sales of their various publications. Course offerings ranged from (German Marks) DM 182.50 to about DM 30,000the equivalent today of approximately $119 to US$19,560. Revenue from monthly, bi-monthly, and other membership offerings could not be estimated in the report. Since 1997 Germany has considered Scientology to be in conflict with the principles of the nation's constitution. It is seen as an anticonstitutional sect and a new version of political extremism and because there is "evidence for intentions against the free democratic basic order" it is observed by the Federal Office for the Protection of the Constitution. In 1997, an open letter to then-German Chancellor, Helmut Kohl, published as a newspaper advertisement in the International Herald Tribune, drew parallels between the "organized oppression" of Scientologists in Germany and the treatment of Jews in 1930s' Nazi Germany. The letter was signed by Dustin Hoffman, Goldie Hawn and a number of other Hollywood celebrities and executives. Commenting on the matter, a spokesman for the U.S. Department of State said that Scientologists were discriminated against in Germany, but condemned the comparisons to the Nazis' treatment of Jews as extremely inappropriate, as did a United Nations Special Rapporteur. Based on the IRS exemptions, the U.S. State Department formally criticized Germany for discriminating against Scientologists and began to note Scientologists' complaints of harassment in its annual human rights reports, as well as the annual International Religious Freedom Reports it has released from 1999 onwards. Germany will continue to monitor Scientology's activities in the country, despite continued objection from Scientology which cites such monitoring as abuse of freedom of religion. France and Belgium have not recognized Scientology as a religion, and Stephen A. Kent, writing in 2001, noted that recognition had not been obtained in Ireland, Luxembourg, Israel or Mexico either. Although the Belgian State Prosecution Service recommended that various individuals and organizations associated with Scientology should be prosecuted, the Belgian courts finally decided in March 2016 that Scientology is not a criminal organization. In Greece, Scientology is not recognized as a religion by the Greek government, and multiple applications for religious status have been denied, notably in 2000 and 2003. In the Netherlands, Scientology was granted tax exempt status in October 2013. The status was revoked in
