Kernrechtsfrage
Whether the event of 5 October 2009 qualified as an accident under Art. 4 ATSG
Extrahierter Entscheid
No. The sequence did not involve an unusual external factor in the form of an uncoordinated movement; the complaint was therefore unfounded.
Extrahierte Begründung
The insured’s sideways collapse was not plausibly caused by the door bang as a disturbance of the movement. The lower courts could reasonably view the collapse as the direct manifestation of the injury itself, not as an accident-causing external factor.
