Kernrechtsfrage
Whether the applicant was denied the right to question or have questioned the sole incriminating witness.
Extrahierter Entscheid
The complaint fails because the applicant expressly waived requesting witness summons at first instance and only belatedly sought an examination on appeal; no exception justified reopening that issue.
Extrahierte Begründung
Article 6(3)(d) ECHR protects confrontation with decisive witnesses, but the right may be waived. Here the waiver was express, the witness was already the subject of a written retraction produced by the defence, and the cantonal court could refuse to order an additional examination.
