Questione giuridica chiave
Whether the site manager's breach of safety rules was an adequate causal cause of the worker's serious bodily injury.
Decisione estratta
The breach was not an adequate cause because the decisive and unforeseeable intervening factor was the worker's own disobedient decision to begin cutting the metal posts before the power line was switched off.
Motivazione estratta
The manager expressly prohibited work on the metal scaffold before shutdown and warned of the danger. He could rely on an experienced foreman to obey this clear instruction. The accident resulted from an extraordinary, self-contained deviation from instructions, not from the initial unlawful order alone.
