Evidence 2 - In Bolton v Stone, the court held that even though there was harm caused to the claimant, as the defendant had put up fences, this meant there was no breach as the cost of prevention was too high. Whilst this is a practical decision, it undermines the legitimacy of a claim if the cost outweighs the risk, it may be seen as letting a defendant off the hook due to financial reasons, rather than what is just in the case.
