Kernrechtsfrage
Whether the first-instance judge could decide the recusal request himself.
Extrahierter Entscheid
No. Because the judge materially assessed the recusal grounds instead of limiting himself to obvious misuse or untimeliness, he breached the rule that a judge challenged by a recusal motion should not decide it himself.
Extrahierte Begründung
The exception allowing a challenged court to decide on a recusal motion applies only to manifestly abusive or clearly unsuitable requests. That was not the case here; the judge should have let the competent substitute decide.
