Landmark Civil Law Cases: The Employer’s Duty to Provide Safe Systems of Work

At Lighthouse Safety, we often remind organisations that safety management isn’t just about compliance, it’s about legal responsibility. A recent reflection on two landmark civil law cases demonstrates how the courts view an employer’s duty to provide a safe system of work, and how that duty cannot simply be delegated.

These cases remain vital learning tools for anyone responsible for health and safety management, supervision, or training.

The Foundational Case: English v Wilsons & Clyde Co (1938)

This case laid the cornerstone for an employer’s non-delegable duty of care.

Mr. English, a miner, was carrying out repair work in a haulage airway when the machinery unexpectedly started. Trapped by the moving equipment, he was fatally crushed.

The company argued that Mr. English could have avoided the accident by using another route or alerting the operator. They also claimed they had delegated responsibility for the work system to an experienced supervisor.

Initially, the company was not found liable. However, the House of Lords overturned this decision, ruling that:

• The duty to provide a safe system of work lies solely with the employer.

• This duty cannot be delegated to another employee or supervisor.

• The employer is vicariously liable for any failure by staff to maintain a safe system.

• It includes providing suitable equipment, employing competent workers, and ensuring effective supervision.

In essence, the ruling made clear that employers carry the full legal responsibility for ensuring safe working conditions, regardless of delegation or experience within the workforce.

The Boundaries of the Duty: Ammah v Kuehne + Nagel Logistics Ltd (2009)

The 2009 case of Ammah v Kuehne + Nagel Logistics Ltd explored the limits of this principle.

Mr. Ammah, a warehouse employee, needed a pamphlet from a high shelf. Instead of using proper equipment, he stood on an upturned plastic box, lost balance, and broke his ankle.

He claimed that the company had failed to provide a safe system of work because they had not warned employees against using boxes as makeshift steps.

However, the Court of Appeal ruled in favour of the employer. It was shown that:

• Safe methods were already provided – including steps, a man-riser, and a forklift truck.

• The employee had access to training and knew the safe procedures.

• The decision to stand on the box was a personal choice, outside the company’s safe system of work.

The court concluded that the employer had fulfilled its duty of care, and that Mr. Ammah’s injury was the result of his own actions, not company negligence.

The Key Lesson for Employers

Both cases reinforce a critical point for all organisations:

Employers must prove that a safe system of work exists, that employees have been trained in it, and that supervision and equipment support its proper use.

If a business can demonstrate these factors through clear evidence, such as training records, risk assessments, and inspection documentation, it is far more likely to successfully defend a liability claim.

If not, the legal and financial consequences can be severe.
