knowingly asserts or disseminates an untrue fact related to another person
Fact: "Something that has really occurred or is actually the case; something certainly known to be of this character; hence, a particular truth known by actual observation or authentic testimony, as opposed to what is merely inferred, or to a conjecture or fiction [OED]
Presumably the inscrutable German lawmakers have included a method to determine the difference between true truths and untrue truths... Or maybe not.
