Question juridique clé
Whether the complainant had standing under Art. 81 LTF despite not asserting civil claims in cantonal proceedings.
Solution extraite
No standing: a private complainant may appeal an acquittal only if, where reasonably possible, civil claims were asserted or properly explained; X. did neither.
Motifs extraits
The proceedings reached judgment stage, so civil claims could have been raised. X. limited his cantonal appeal to criminal conviction requests and did not set out any civil claim or justify the omission in his federal appeal. He therefore failed to show a legally protected interest.
