Key Tension
The key tension is stability and development particuarluary as common law must balance stability/certainity against development/adaptability
Atkins:
Common law should develop to meet changing social conditions
Earlier negligence cases are examples of a broader underlying principle, not isolated individual case
Neighbour principle provided a basis for extending liability
Favoured judicial development
Justice and reasonable foreseeability justified development
Buckmaster:
existing law should remain stable & significant change left for Parliament
Earlier engligence cases were narrow exceptions not evidence of a general principle
favoured judicial restraint
stability provides certainity and predictbaility
concernted that expansion of liability would create a chilling effect on society
it would open the floodgates
