“… [O]nce the [claimant] has established that there was a breach of an enactment which made the employer absolutely liable, and that breach caused the accident, he need do no more. But it is then open to the employer to set up a defence that, in fact, he was not in any way in fault, but that the [claimant] employee was alone to blame.”
“whether the fault of the employer under the statutory regulations consists of, and is co-extensive with, the wrongful act of the employee. If there is some fault on the part of the employer which goes beyond, or is independent of the wrongful act of the employee, and was a cause of the accident, the employer has some liability.”
“The doctrine of absolute liability, which was invented by the courts, can lead to absurd results when coupled with the employer’s vicarious liability. It would be absurd if, notwithstanding the employer having done all he could reasonably be expected to do to ensure compliance, a workman, who deliberately disobeyed his employer's orders and thereby put the employer in breach of a regulation, could claim damages for injury caused to him solely by his own wrongdoing. So the courts have quite properly introduced a qualification of the employer's absolute liability. A principle of law has been established that, although in general the employer is under absolute liability in respect of such a breach, the employer may have a defence to an action against him by an employee who is also in breach.”
“The employer’s duty to comply with the requirements of the Regulation differs from that of his employee. The employer, at any rate when he is a Corporation, must needs perform his duty vicariously through his officers, servants, agents or contractors; but he does not thereby rid himself of his duty. He remains vicariously responsible for any failure by any one of them to do whatever was necessary to ensure that the requirements of the Regulations were complied with; and among those for whose failure he is prima facie vicariously liable is any employee who is himself under a concurrent statutory duty to comply with those requirements. The employee’s duty, on the other hand, is in respect of and is limited to his own acts or omissions. He is not vicariously liable for those of anyone else.”
