Re Polemis [1921] 3 K.B. 560
Facts
A ship was chartered for wartime cargo service. While cargo was being handled, a plank fell into the hold through the negligence of people for whom the charterers were responsible. Flammable vapour had accumulated there, and the impact produced ignition and a fire which destroyed the vessel. Some damage from dropping a plank was foreseeable, but the resulting fire was not the kind of damage that had been anticipated. The owners sought compensation, raising the question whether the unexpected character of that direct consequence limited responsibility once the handling had been found negligent.
Legal Issue
Under the remoteness approach then applied, was the charterer liable for an unforeseeable fire that directly resulted from negligent cargo handling?
Held
The Court of Appeal held the charterers liable for the destruction of the ship. The negligent act could foreseeably cause some damage, and the fire was treated as its direct consequence. Under the approach adopted, it was unnecessary that the particular kind of damage ultimately suffered had been foreseeable once negligence was established. That was a historical direct-consequence test, not liability for every consequence irrespective of intervening causes. The Wagon Mound No 1 subsequently rejected that approach in favour of reasonable foreseeability of the relevant kind of damage. Re Polemis should therefore be used to explain the development of remoteness, rather than as the governing rule for an ordinary modern negligence claim.
⭐ Legal Principle
Re Polemis historically imposed liability for an unforeseen kind of damage where it directly followed an act already shown to be negligent. The Wagon Mound No 1 displaced that direct-consequence approach with foreseeability of the relevant kind of damage as the ordinary negligence remoteness test.
Significance
The case separates the foreseeability needed to establish negligent conduct from the remoteness test once negligence is established. Its historical answer to the second question is no longer the ordinary approach. A good comparison with The Wagon Mound explains why directness alone proved too broad. The thin-skull rule addresses a different issue, the claimant's unusual susceptibility once the relevant injury is within responsibility, and should not be described as preserving Re Polemis wholesale or making negligence strict liability.
Common exam questions about this case
Why did the unforeseeable fire not defeat the historical claim?
Dropping the plank was negligent because some damage was foreseeable, and the fire was regarded as a direct result of that act. The Court of Appeal then treated the unexpected kind of damage as immaterial. That explains the original outcome under the direct-consequence approach used in 1921.
What changed with The Wagon Mound No 1?
The ordinary remoteness inquiry came to require reasonable foreseeability of the relevant kind of damage rather than directness alone. Re Polemis therefore cannot determine a modern negligence problem without qualification. State its historical test and then identify the later authority that displaced that approach.
Is the thin-skull rule the same as Re Polemis?
No. The thin-skull rule concerns the extent of injury arising from a claimant's unusual susceptibility once the relevant harm is within the defendant's responsibility. Re Polemis concerned an unforeseen kind of damage. Conflating them hides the distinction between the type of harm and its unexpectedly serious consequences.
