Key legal question
Whether requalifying conduct from robbery to coercion without prior warning violated the accused's defense rights and the accusation principle.
Extracted holding
No violation occurred because coercion was a foreseeable element of the charged robbery and, in any event, the alleged defect was cured on cantonal appeal where the accused could contest the requalification.
Extracted reasoning
Robbery also protects personal liberty and includes coercion. Given the remaining elements charged and the appellant's own defense, he had to expect that coercion might be retained. The cantonal cassation court heard and fully reviewed the argument, curing any hearing defect.
