Question juridique clé
Whether the dismissal of the juvenile investigation for alleged bodily assault/tätlichkeit against B.___ was lawful.
Solution extraite
The dismissal was upheld because the available evidence did not make a conviction likely; a trial would almost certainly end in acquittal.
Motifs extraits
The statements remained irreconcilably conflicting, but the file contained credible indications of a mutual play fight. Further evidence was unlikely to clarify the matter, so under in dubio pro duriore the prosecutor could discontinue the case.
