Here are hotlinks to the sections on Germany of the annual reports.
In 1997, the U.S. State department issued a special report on religious freedom in which Scientology is quoted as being discriminated against in Germany. Somewhat surprisingly, the treatment of Scientology in other European countries is not mentioned.
Unfortunately, the U.S. Congress is rather uninterested in human rights violation by the U.S. To learn more about human rights violations in the U.S., read Amnesty International's Rights for All pages.
The CSCE, also called "Helsinki Commission", is
an independent agency of the United States Government mandated to monitor and encourage compliance of the participating States with the Helsinki Final Act and subsequent documents. It is composed of nine members from the United States Senate and nine members from the House of Representatives, as well as one member each from the Departments of State, Defense, and Commerce.(from the CSCE homepage). Note that the CSCE is not really related to the OSCE.
In 1993, the CSCE issued a report on Germany titled "Human Rights and Democratization in Unified Germany". This report contains the following paragraph on Scientology:
Members of the Church of Scientology, for example, have protested harassment harassment in the form of firings, expulsion from political parties, and discriminatory treatment from local and state authorities, solely based on their affiliation with Scientology. Indeed, in one recently publicized case in which the state of Baden-Wuerttemberg broke off contract negotiations with jazz musician Chick Corea upon learning that Mr. Corea was a Scientologist, state officials explained quite unapologetically to the Helsinki Commission that "The position that Baden-Wuerttemberg takes toward Scientology is shared by all other German States ... We judge the practices of Scientology in a very critical manner", and "Neither would we engage in a contractual agreement with an artist who is either radically to the left or radically to the right because we feel that it would be bad advertising for the State of Baden-Wuerttemberg."(The report is also available via gopher from server.gdn.org in Common Ground Format.)
In 1997, the CSCE had a hearing about violation of religious tolerance in Europe. You can find the full protocol at http://www.house.gov/csce/hearing.htm or excerpts concerning Scientology here.
In September 1997, Abdelfattah Amor, then Special Rapporteur of the U.N. Commission of Human Rights, visited Germany and afterwards issued this report.
Amnesty International annual reports:
Neither has Human Rights Watch in its April 1995 report "Germany for Germans" mentioned Scientology.Notably, Scientology is not interested in Human Rights violations anywhere on the world unless its own rights are affected. For example, Amnesty International issues country reports for the U.S. as well (which the U.S. State department conveniently forgets). These deal with the death penalty, the forcible return of asylum seekers back home, and racism.
