Key legal question
Whether the federal appeal against the cantonal recusal decision was admissible and what its scope was
Extracted holding
The appeal was admissible as a separately issued final cantonal-instance interim decision on recusal, but only the question of the prosecutor's apparent bias could be reviewed.
Extracted reasoning
Under Art. 92(1) BGG, recusal decisions are directly appealable. Challenges unrelated to recusal, including complaints about KESB or past cost decisions, fall outside the object of the proceedings.
