Questione giuridica chiave
Whether the appellants were criminally liable for negligent bodily injury by omitting roof safety measures
Decisione estratta
The omission could not be attributed to them because, in the horizontal division of labour, they were entitled to rely on D. SA to take the necessary precautions until its work was completed.
Motivazione estratta
The Federal Court held that workplace safety rules required effective fall protection, but responsibility was divided between the contractors. Under the trust principle and art. 9 OPA, C. SA's employees could assume D. SA would secure the opening or warn them. No special circumstances displaced that reliance.
