Questione giuridica chiave
Whether the statements in the open letter constituted defamation under Art. 173 StGB and whether the good-faith defense applied.
Decisione estratta
The terms used were defamatory; the defendant failed to show that he had serious grounds to believe the accusations were true or that he had adequately verified them.
Motivazione estratta
A criminal-conduct allegation is generally proved true by a corresponding conviction, which was absent. The defendant relied only on his own interpretation of the land-servitude dispute and had no justified basis for his accusations, especially after prior judgments had already classified similar statements as defamatory.
