Key legal question
Whether the rear-end collision caused or aggravated the lumbar disc-related complaints under accident insurance law.
Extracted holding
The causal link was denied because the accident was not of special severity and not suitable to injure even a healthy intervertebral disc.
Extracted reasoning
For disc herniations and aggravations of pre-existing disc disease, accident causation is exceptional and requires a particularly severe accident with immediate symptoms and incapacity. The collision delta-v was only around 10–15 km/h, so the special-severity threshold was not met.
