it is important to establish whether a duty exists so that the right cases can come before the courts
the law does not impose a duty on someone to prevent foreseeable harm; it only imposes a duty where someone has assumed responsibility & created a risk to others
Robinson has clarified when the Caparo test is needed – only in novel cases not covered by precedent
disadvantages of the law around duty
the Caparo test has been criticised for its lack of clarity, making it difficult for lawyers to advise clients effectively
advantages of the law around breach
it is fair that D is judged against what is common practice & the knowledge of the time
allowing individual characteristics of C to be considered offers more vulnerable Cs better protection
courts consider whether all appropriate precautions have been taken by D & balance this against the cost & effort of taking those precautions
it is fair that there should be no liability if a risk is taken to benefit society
disadvantages of the law around breach
D is judged objectively & must reach the standard of the reasonable man – this may operate unfairly against some Ds
it is unfair to expect the same standard of care from learners as more experienced people performing that task
advantages of the law around damage
the principles of factual causation are generally fair – the 'but for' test allows all Cs to be treated in the same way
D will not be liable if a new intervening act is the cause of damage
disadvantages of the law around damages
the rules on remoteness of damage can be unfair to C as they may limit D's liability
the approach taken by the courts in determining what 'type' of damage is foreseeable may not be fair
