Kernrechtsfrage
Whether the jump from the collapsing ladder and resulting back pain constituted an accident under the law.
Extrahierter Entscheid
The existing medical file did not allow a definitive answer; the matter had to be medically clarified further.
Extrahierte Begründung
A jump to avoid an overturning ladder may be an instinctive defensive reaction and thus an unusual external factor if it triggers an injurious internal bodily process. However, the records were insufficient to determine whether the acute lumboischialgia was caused in this way.
