Kernrechtsfrage
Whether the complaint based on Art. 6(3)(d) ECHR could be heard despite not being raised before the cantonal cassation court.
Extrahierter Entscheid
The complaint was inadmissible because it had not been raised before the last cantonal instance and no exception to exhaustion applied.
Extrahierte Begründung
A public-law appeal may be brought only against decisions of the last cantonal instance; new grievances are barred unless an exception applies. The appellant did not invoke this ECHR ground before the cantonal court and alleged no denial of justice for its omission.
