I saw this earlier today and thought it might be of interest, considering that other German court decisions are currently being discussed on Hacker News: https://news.ycombinator.com/item?id=44912085

Note: the headline is somewhat misleading. The first line of the article reads

> A court in Hamburg, Germany, has stated in the details of a ruling concerning a Karl Marx reading group that Marx’s teachings may be contrary to the “free democratic basic order.”
