Key legal question
Whether the recusal request against Helen Leimbacher had to be granted under Art. 56 lit. f StPO
Extracted holding
No objective appearance of bias arose from the limited child-protection interviews; the request was unfounded.
Extracted reasoning
The interviews were part of social-pedagogical work in a different proceeding, were brief, focused on the children's placement and welfare, not on the criminal charge itself, and showed no statements or conduct indicating prejudgment.
