Questão jurídica principal
Whether Oberrichter A.________ had to recuse himself because he had earlier acted as prosecutor in the same criminal matter.
Decisão extraída
Yes. Prior prosecutorial involvement in the prosecution that led to the sentence creates an objective appearance of bias when the same person later sits as judge in proceedings on conditional release from that sentence.
Fundamentação extraída
Under Art. 30 para. 1 BV, Art. 6 para. 1 ECHR, and Art. 56 lit. b StPO, impartiality is compromised where a judge previously participated in the same criminal case. The court extended its earlier case law on later membership in a release commission to judicial participation in the release proceedings themselves.
