Key legal question
Whether the cantonal chamber arbitrarily held that the complaint against A.________ validly covered the later theft/soustraction allegations.
Extracted holding
The complaint-scope question could remain open, because the decision had to be annulled on other grounds.
Extracted reasoning
A complaint is directed at a factual situation, not at named persons only; however, extension is limited and depends on the offense and procedural conditions. The court left the precise cantonal-law issue undecided.
