I’ve gone and read through a number of in-country reports (from the region) on the topic. First, this fine is still in limbo...the city clerk forwarded it to a the prosecutor and typically it’d be collected. However, the parents also turned in a complaint and there’s likely to be a judge assigned now to review this.
German schools have some ability to mandate socially-related topics...and religion is typically not forced upon students. So, the judge I think....will be asking some stupid questions about who validated this and if this opens up other doors (a Satanist group could demand students should visit their operation, or a Scientology group).
I have doubts that the 300 Euro fine will be enforced. One of the other issues is that in a neighboring state (North Rhineland Westphalia)....there is a spring state election, and this type of action could be picked up by anti-CDU or anti-SPD political folks and shift the election in a different way.
I thought Scientology was prohibited in Germany. Wasn’t it in the 1990s?
