Question juridique clé
Whether the recusal request against the investigator was filed without delay under Art. 58 StPO
Solution extraite
The request was filed only about two months after the appellant allegedly learned of the supposed bias and was therefore not made without delay; it was untimely.
Motifs extraits
A recusal request must be brought within days, and a party may not continue participating in the proceedings while knowing the ground for recusal. Because the appellant waited too long, no statement under Art. 58(2) StPO was required.
