## Facts

- A breach occurred in the riverbank of the River Deben, resulting in substantial flooding of Kent's farmland.
- The East Suffolk Rivers Catchment Board, responsible for river management and flood prevention, undertook repairs to the breached bank.
- The Board's repair efforts were delayed and inefficient, which led to prolonged flooding and additional damage to Kent's property.
- Kent sued the Board for negligence, alleging that their inefficient response exacerbated the flooding and consequent damage.
- At first instance, the court held in favor of Kent, finding the Board liable for negligence.
- The Board appealed the decision.

## Issues

1. Whether a public authority exercising statutory powers is liable for negligence when its inefficient actions fail to mitigate harm but do not actively worsen the situation.
2. Whether mere inefficiency or poor execution in the performance of a statutory duty constitutes actionable negligence by a public body.
3. Whether liability for public authorities should be limited to instances where their actions directly exacerbate the harm suffered.

## Decision

- The Court of Appeal reversed the initial decision, holding that the Board was not liable for mere inefficiency in performing its statutory duty.
- The court determined that liability only arises if the public authority's actions actually worsen the situation, not for a mere failure to improve it.
- It was held that the Board's statutory powers conferred discretion rather than imposing an absolute duty to prevent flooding.
- The court concluded that the Board's actions did not amount to misfeasance, as the flooding was not made worse by their conduct.

## Legal Principles

- Public authorities exercising statutory powers are only liable in negligence if their conduct directly causes additional harm.
- Statutory duties often provide discretionary authority, not an absolute obligation to prevent harm.
- Mere inefficiency or poor execution in addressing a problem does not amount to legal liability unless it results in aggravated harm.
- A distinction exists between nonfeasance (failure to act) and misfeasance (improper performance), with only the latter potentially giving rise to liability.

## Conclusion

The court established that a public authority is not liable for harm resulting solely from inefficient execution of statutory powers unless its actions actively worsen the situation. This decision reinforced limits on negligence claims against public bodies, requiring active causation of harm for liability to arise.
