Key legal question
Whether the insured's complaints were in a natural and adequate causal connection with the alleged tick bite.
Extracted holding
The file was unclear and contradictory; the case required further medical clarification through an external expert opinion.
Extracted reasoning
The symptoms could fit Lyme borreliosis, but some complaints predated the alleged bite and the serological findings were interpreted differently by the doctors. The court could not resolve the specialized medical dispute by free assessment.
