> Are you a lawyer in DACH/Germany?
Nope :-), just a normal citizen, but sometimes I am curious enough to look up a law, plus sometimes I need to refer to/look up some law in my day job as a civil engineer, too.
When you need to do that, it's not too hard to stumble upon the existence of that page through some web searches, plus the German Wikipedia often links to that page, too (as well as to some alternative platforms run by private entities, which sometimes provide some added value, e.g. buzer.de provides change history since 2006, too, other pages link relevant court decisions, etc. etc. – but gesetze-im-internet.de is the official page run by the federal government itself).
