The criminal code (Strafgesetzbuch) Chapter 7 (Offences against public order), Paragraph 130 (Incitement to hatred) of the Federal Republic of Germany defines when a person is guilty of Volksverhetzung.
For any hate speech to be punishable as Volksverhetzung, the law requires that said speech be "qualified for disturbing public peace" either by inciting "hatred against parts of the populace" or calling for "acts of violence or despotism against them", or by attacking "the human dignity of others by reviling, maliciously making contemptible or slandering parts of the populace".
"Germany places strict limits on speech and expression when it comes to right-wing extremism" or anything reminiscent of Nazism.
[6] Offences contrary to § 130 of the Criminal Code committed abroad, whether by German nationals or foreigners, can be pursued as a domestic crime when they so act as if they had been committed within the country, affecting the public peace in Germany and violating the human dignity of German citizens.
It is sufficient, for example, that criminal content on the Internet, for example in the form of a HTML page, can be accessed from Germany.
[7] Hence, for example, the jurisdiction of German courts can be applied for offences of sedition (Volksverhetzungsdelikte) committed abroad.
