Key legal question
Whether the nullity complaint could challenge cantonal procedural-law objections and evidentiary assessment.
Extracted holding
The complaint was admissible only for alleged violations of federal law; challenges to cantonal procedural rules and to evidence appraisal were not reviewable.
Extracted reasoning
Under Art. 269(1) BStP, only federal-law violations may be raised; factual findings and evidentiary assessment are excluded under Art. 273(1)(b) BStP.
