Questão jurídica principal
Whether the HUG were liable for the harm caused by the mistaken biopsy and ensuing arm injury
Decisão extraída
The cantonal finding of unlawful and negligent conduct, natural and adequate causation, and liability was not arbitrary.
Fundamentação extraída
The first biopsy was unnecessary because the suspicious lesion was on the 10th rib, not the 9th. The operative mistake was supported by the medical evidence, the symptoms began three days later, and the biopsy was a medically known trigger for such complications.
