Question juridique clé
Whether the insured participated in a brawl within the meaning of Art. 49(2) OLAA and whether the injury was causally linked to that participation.
Solution extraite
The insured voluntarily took part in the brawl, and the ceinture strike remained causally linked to that participation.
Motifs extraits
The participation requirement is broader than criminal rixe; it is enough to enter the zone of danger. The brief lapse of time, continuing tension, and the insured's approach to the others supported the finding that the later blow was a continuation of the conflict, not an independent act of revenge.
