Can you say more about what these small mistakes were? Would they affect the interpretation of the law?
buzer.de actually has a list of things that differ in their consolidation compared to gesetze-im-internet.de: https://www.buzer.de/quality.htm
In that list you can actually find mistakes that would alter the interpretation. But I think this also sounds worse than it is. It's just a funny thought that whatever source you are using, you are essentially trusting one party to not have made any mistakes, consolidating 1000s of pages of pdfs :)
But my point is that, as far as I know, there is no official version of the final text. The official publications are made in the Bundesgesetzblatt (which had been privatized in the past, but that's another story). The publications might look like this:
1947: We hereby make the following text a law called Grundgesetz "Artikel I: Human dignity is inviolable"
2026: We hereby change the law called Grundgesetz by changing the first article to say "Human or Alien" instead of "Human".
Now there are a lot of entities that will consolidate these changes into a final text. But this consolidation isn't done officially. So, while in this example its easy to see, that in 2026 the law would read "Human and Alien dignity is inviolable", it becomes less clear when these changes are spread over 80 years and are only available as PDFs.
