Solution extraite
The term 'competition' includes the ULM championship; the exclusion validly applies.
Motifs extraits
The cantonal court's interpretation was not arbitrary. It could rely on the event's official championship character, the organizer's statutes and regulations, the testimony of the organizer, and French authorities' own classification of the event as a competition.
