Key legal question
Whether the insured's ongoing paralysis was compensable under Art. 6(3) UVG as a treatment-related injury after the plexus anesthesia.
Extracted holding
A treatment-related injury was not established with the required degree of probability; no liability under Art. 6(3) UVG.
Extracted reasoning
The medical file did not objectively prove a neurological lesion. The only support for causation was temporal proximity, which was insufficient and amounted to an impermissible post hoc inference.
