Key legal question
Whether cantons may criminalize public nude hiking under Art. 335(1) StGB.
Extracted holding
Yes. The federal sexual-offense regime is exhaustive as to sexual integrity, but non-sexual public nudity may still be sanctioned by cantonal minor-offense law.
Extracted reasoning
The repeal of old Art. 203 aStGB did not remove cantonal competence over public morality or good manners; the federal legislature did not preclude cantonal punishment of non-sexual public nudity.
