Key legal question
Whether the refusal to hear defense witnesses violated the right to be heard
Extracted holding
The refusal did not violate the right to be heard because the requested evidence was not shown to be relevant and the decisive fact—the appellant's knowledge of the falsity of the allegations—was already established.
Extracted reasoning
The cantonal court could refuse evidence where it was irrelevant or incapable of changing the outcome. The challenged statements were already objectively defamatory and contained in a public text. The appellant failed to show arbitrariness in the finding that he knew the allegations were false.
