“Where any person suffers damage as the result partly of his own fault and partly of the fault of any other person or persons, a claim in respect of that damage shall not be defeated by reason of the fault of the person suffering the damage, but the damages recoverable in respect thereof shall be reduced to such extent as the court thinks just and equitable having regard to the claimant's share in the responsibility for the damage.”
“Whilst causation is the decisive factor in determining whether there should be a reduced amount payable to the plaintiff, nevertheless, the amount of the reduction does not depend solely on the degree of causation. The amount of the reduction is such an amount as may be found by the court to be "just and equitable", having regard to the claimant's "share in the responsibility" for the damage. This involves a consideration, not only of the causative potency of a particular factor, but also of its blameworthiness.”
“A very young child cannot be guilty of contributory negligence. An older child maybe. But it depends on the circumstances. A judge should only find a child guilty of contributory negligence if he or she is of such an age to be expected to take precautions for his or her safety: and then he or she is only to be found guilty if blame should be attached to him or her. A child has not the road sense or experience of his or her elders. He or she is not to be found guilty unless he or she is blameworthy.” 10.2 Lord Salmon LJ at p.1391: “The question as to whether the plaintiff can be said to have been guilty of contributory negligence depends on whether an ordinary child of 13 could be expected to have done more than this child did. I did say "ordinary child". I did not mean a paragon of prudence; nor do I mean a scatter-brained child; but the ordinary child of 13.”
“54 …I find that (the defendant) was travelling in a manner that was outside Caine's experience and anticipation… Caine looked straight at the car but carried on running. The inference is that he misjudged the car’s speed and/or distance. The fact that Caine was crossing in the vicinity of a crossing is also an important distinction [from the claimant in the case of AB v Main where a child of 8 years 10 months was found to have been contributorily negligent]. … 60 Therefore, the only reasonable inference is that he believed the car would stop at the crossing for him. That involved misjudging the car's capacity to stop in time. The Green Cross Code confirms that "Many children cannot judge how fast vehicles are going or how far away they are". It seems to me that it is even more difficult for a child of 8 to judge the stopping distance for a car so as to understand that while the car should stop at the crossing it may be travelling at such a speed that it is unable to do so in time. … 62 I find that this was a case of momentary misjudgment on Caine's part balanced against reckless conduct on the part of the defendant, whose driving was outside Caine’s expectation based on his understanding and experience. In my judgment it would not be just and equitable to make a finding of contributory negligence in the circumstances and I decline to do so.”
