Established the modern law of negligence and the neighbour principle, the doctrinal starting point for any duty-of-care discussion.
The high-water mark of the two-stage test; you must know it to understand why later authority pulled back from it.
Replaced the Anns approach with the three-part test (foreseeability, proximity, fair-just-reasonable) that still anchors novel-duty analysis.
Clarified that Caparo is not a universal test; only novel cases reach the three-stage analysis, established categories control the rest.
