Cadman vs HSE: 2006 Health & Safety Case

By Melissa MartinMarch 27, 2026

The Cadman v Health and Safety Executive (HSE) case in 2006 was a landmark decision in UK health and safety law, significantly impacting the interpretation of the Reporting of Injuries, Diseases, and Dangerous Occurrences Regulations (RIDDOR). This article explores the key aspects of this case, its implications, and the subsequent changes in RIDDOR reporting.

Background: The Cadman Case

In 2006, the HSE prosecuted Cadman Ltd, a construction company, for failing to report an incident where a worker suffered a fractured skull. The company argued that the injury was not work-related, as it occurred when the worker slipped on a banana skin while walking through a public street on his way to work. The HSE, however, maintained that the injury was work-related as it occurred during the worker's journey to the workplace, which was considered part of his working time.

Key Legal Issues

Work-Related Injury Definition

At the heart of the Cadman case was the definition of a 'work-related' injury. The HSE interpreted RIDDOR to include injuries that occur during the course of employment, even if they happen outside the workplace. Cadman Ltd, however, argued that the injury only became work-related once the worker started his duties at the workplace.

Reporting Obligations

Another key issue was the obligation to report injuries. The HSE contended that Cadman Ltd should have reported the incident, as it was a 'work-related' injury. Cadman Ltd, on the other hand, argued that they were not obligated to report the injury, as they did not believe it was work-related.

Judicial Decision

The case reached the Court of Appeal, which ruled in favor of the HSE. The judges agreed with the HSE's interpretation of RIDDOR, stating that an injury is 'work-related' if it occurs during the course of employment, regardless of the location. The court also held that employers have an obligation to report any work-related injury, regardless of their personal belief about the cause of the injury.

Implications of the Cadman Case

Broadened Scope of RIDDOR

The Cadman case significantly broadened the scope of RIDDOR. It established that injuries occurring during the course of employment, even outside the workplace, must be reported. This includes commuting to and from work, as well as any work-related travel.

Enhanced Employer Obligations

The case also increased employers' obligations. They must now report any work-related injury, regardless of their personal belief about its cause. This means employers must report injuries they believe are not work-related, and allow the HSE to make that determination.

Changes to RIDDOR After Cadman

Following the Cadman case, RIDDOR was amended in 2012 to reflect the broader interpretation of 'work-related' injuries. The regulations now explicitly include injuries that occur during the course of employment, regardless of location. The 2012 amendments also clarified employers' reporting obligations, emphasizing that they must report any work-related injury, regardless of their personal belief about its cause.
