## Facts

- During World War II the steamship The Oropesa collided in the North Atlantic with the vessel The Manchester Regiment, causing serious damage.
- After the collision the captain of The Manchester Regiment ordered a lifeboat launched to transfer passengers and crew to the apparently less-damaged Oropesa.
- The lifeboat capsized in heavy seas and several occupants died.
- Representatives of the deceased sued, alleging the collision was due to the negligence of The Oropesa’s crew.
- The defendants contended that the captain’s decision to launch the lifeboat was an independent, unforeseeable act that constituted a novus actus interveniens, thereby severing the causal link between their negligence and the fatalities.

## Issues

1. Whether the decision to launch the lifeboat amounted to a novus actus interveniens that broke the chain of causation between the collision and the deaths.
2. Whether the deaths and related losses were nonetheless legally attributable to the negligent navigation of The Oropesa.

## Decision

- The Court of Appeal rejected the argument that the rescue attempt was an intervening act; it was a natural, reasonable and foreseeable response to the emergency created by the collision.
- Because the chain of causation remained intact, liability for the deaths rested with the negligent crew of The Oropesa.
- The court affirmed that, in general, acts of necessity or rescue undertaken in the face of danger caused by a defendant’s negligence do not absolve that defendant of liability.

## Legal Principles

- Causation in negligence comprises factual causation (“but for” test) and legal causation (remoteness and intervening acts).
- An intervening act will break the chain only if it is unreasonable or unforeseeable; reasonable rescue efforts are ordinarily foreseeable.
- Human actions taken in emergencies are treated as foreseeable when assessing legal causation.
- Negligent parties remain liable for ensuing harm where subsequent rescue attempts are a foreseeable consequence of their breach.

## Conclusion

The Court of Appeal held that the foreseeable and reasonable rescue attempt following the collision did not constitute a new intervening act; consequently, the deaths were legally caused by the negligent navigation of The Oropesa, and liability was upheld against its owners.
