Questione giuridica chiave
Whether the Zurich Kassationsgericht violated Art. 9 BV by applying a new substantiation requirement without prior notice in the cassation complaint procedure.
Decisione estratta
No unlawful practice change was shown; the court merely applied the existing rüge principle and required adequate substantiation of the alleged defense defect.
Motivazione estratta
The decision did not depart from prior practice but insisted that a complainant challenging allegedly insufficient defense must indicate, at least in outline, which concrete exculpatory circumstances existed and how a better defense could have mattered. The federal complaint did not show arbitrary or overly formalistic application.
