East Suffolk Rivers Catchment Board v Kent [1940] UKHL 3 (09 December 1940)

A high tide breached a wall protecting the respondents' farmland, causing flooding. The appellant Catchment Board had statutory power but no duty to repair. They attempted repairs inefficiently, taking 164 days instead of 14. The House of Lords held that having only a power, not a duty, the Board was not liable for damage caused by delay in exercising that power.

Facts

On 1st December 1936, an exceptionally high spring tide reinforced by a northerly gale caused the waters of the River Deben in Suffolk to breach ancient walls protecting adjoining marshland. One breach, measuring 20-30 feet, flooded approximately 50 acres of marsh pastures belonging to the respondent Porter and occupied by the respondent Kent.

The appellant East Suffolk Rivers Catchment Board was constituted under the Land Drainage Act 1930 and had statutory power (but no duty) to repair drainage works including such walls. The Board attempted to repair the breach but used inefficient methods and inadequate staff. The trial judge found that whereas the gap could have been closed in 14 days with reasonable skill, it actually took 164 days to complete the repair.

Issues

Principal Legal Question

Whether a statutory body with power (but no duty) to act becomes liable in negligence for failing to exercise that power with reasonable care and expedition once it has voluntarily undertaken to act.

Secondary Issue

Whether the damage suffered by the respondents was caused by the Board’s negligent delay or by the original breach caused by natural forces.

Judgment

The House of Lords allowed the appeal by a majority of 4-1 (Lord Atkin dissenting).

Majority View

The Lord Chancellor held that since the Board was under no statutory duty to repair but merely had power to do so, and since the flooding was caused by the forces of nature rather than by the Board’s actions, the respondents had no claim. The Board’s unsuccessful efforts to stop the flooding did not make them liable for damage they did not cause.

Lord Thankerton agreed that once the Board entered the land they owed a duty to conduct operations with reasonable care to avoid causing damage, but held that the respondents failed to establish that their damage was caused by the Board’s breach rather than by the original flood breach.

Lord Romer stated the principle that where a statutory authority has a mere power, it cannot be made liable for damage sustained by failure to exercise that power. If they embark upon execution of the power, their only duty is not to add to the damages that would have been suffered had they done nothing.

Lord Porter concurred, noting that the damage was not caused by any positive act of the appellants but would have occurred to the same extent if they had taken no steps at all.

Dissenting Opinion

Lord Atkin dissented, holding that the Board owed a duty to the respondents to use reasonable care, including reasonable despatch, in conducting the repair work. He considered that if the respondents could prove extra damage resulting from the delay beyond 14 days, they should succeed.

Implications

This case established an important distinction between statutory duties and statutory powers in the law of negligence. A public body with discretionary powers is not liable for failing to exercise those powers, even if exercising them would have prevented damage. Once they choose to act, they are only liable for damage positively caused by their intervention, not for damage that would have occurred anyway had they done nothing. This principle protects public authorities from liability when exercising discretionary powers and recognises that decisions about when and how to exercise such powers involve considerations of policy, resources and competing priorities that should not be second-guessed by courts.

Verdict: Appeal allowed. The East Suffolk Rivers Catchment Board was held not liable for the damage caused by the prolonged flooding, as they had only a statutory power and not a duty to repair, and the damage was caused by natural forces rather than by their intervention.
