Questão jurídica principal
Whether the federal appeal was admissible despite the cantonal cassation ruling
Decisão extraída
The appeal was timely and admissible insofar as federal review was available; constitutional-law complaints that had to be raised before the cantonal cassation court were not entered into.
Fundamentação extraída
The cassation court's non-entry did not mean the cantonal remedy was unavailable in principle, and Article 75 BGG required exhaustion of remedies for issues reviewable at cantonal level.
