Question juridique clé
Whether E. committed negligent homicide under Art. 117 CP by not checking the trench and by continuing the maneuver after seeing the victim.
Solution extraite
The operator did not breach the duty of prudence in a blameworthy way; he could assume the trained coworker knew the risks, and he was entitled to finish the maneuver already underway once he saw him briefly in the trench.
Motifs extraits
The court applied the subsidiarity principle: because E. acted actively, the case was assessed as commission. On the established facts, the victim was a semi-trained mason responsible for the crew and familiar with the risks; he was visible only briefly, so E. could initially expect him to move away and was not required to stop instantly.
