Question juridique clé
Whether the victim had standing to appeal the acquittal because the decision could affect his civil claims.
Solution extraite
The victim had standing because he had participated below and his civil claims were sufficiently asserted; the acquittal could affect their adjudication.
Motifs extraits
Under the applicable version of Art. 81 LTF, a victim may appeal if the decision can affect civil claims. Although he had only sought civil claims in principle, this was acceptable because a full quantification would likely have been deferred to civil courts due to the disproportionate effort required.
