To what cases is the judge referring to here?
None: neither the quoted article (2023-06-02 05:57: Prozess gegen Lina E.: Stadt Leipzig verbietet Solidaritäts-Demonstration) given in the english version of Wikipedia nor the german Wikipedia version (Dresdner Linksextremismusprozess – Wikipedia uses the quote given in the english version.
In the article itself, the name 'Hans Schlueter-Staats' is used only once:
The arrest warrant against them will be suspended against conditions, said Hans Schlueter-Staats, presiding judge of the State Protection Chamber at the Dresden Higher Regional Court, on Wednesday evening at the end of the verdict. She only has to serve the remainder of the sentence if the verdict becomes final.
Assume that, for whatever reason, someone added a fabricated quote, in the Wikipedia page, that is not contained in the given source hoping that nobody would notice (either because the reader can't read German or simply wouldn't look).
It would be very strange for a judge whos primary duty, in a civil law system, is to read the law as written, to give a personal opinion about previous rulings (which was the reason I looked: to read the exact German text).
Whoever fabricated that quote was obviously unaware of this or didn't care hoping that others would simply assume it to be correct due the given source of a newspaper that has a reputation as being a reliable source.
