Kernrechtsfrage
Whether the criminal appeal was admissible and whether alleged defects in the video interviews and first police questioning could be raised for the first time before the Federal Supreme Court.
Extrahierter Entscheid
The complaint on those procedural defects was inadmissible because the objections could and should have been raised before the cantonal courts.
Extrahierte Begründung
The cantonal remedies must be exhausted materially; new constitutional arguments are barred when they could have been invoked earlier.
