Question juridique clé
Whether the cantonal court, after a federal remand, could broaden serious bodily injury to additional injuries not previously contested.
Solution extraite
No. The remand bound the cantonal court to the federal reasoning and to the issues left open; extending Art. 122(3) CP to new injuries would have amounted to a new conviction and violated the prohibition of reformatio in peius.
Motifs extraits
Under the former remand rule, the cantonal court had to follow the federal court's legal considerations and could only decide questions left unresolved. Matters not validly challenged in the prior appeal were final and could not be revisited or enlarged on remand.
