Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 1 His Honour Judge Robinson: Introduction 1. In the early hours of 9 August 2016, the Claimant and Aaron Brown were driven by Aaron’s brother, Dean Brown, to the Moo Moo night club in Cheltenham. I shall refer to the Brown brothers by their first names. The car was a three-door hatch back Seat Ibiza. All three drank alcohol in the club. There came a time when the Claimant, who was clearly drunk, was assisted out of the club by Aaron and Dean and placed in the front passenger seat of Dean’s car. He leaned out of the car to be sick on the ground. Aaron and Dean returned to the club to continue drinking. 2. About an hour or so later, Aaron and Dean left the club, returned to the car and got into it. Aaron was in the rear off side passenger seat. The Claimant was still in the front passenger seat. The car would not start. Aaron got out of the car to return to the club to find some jump leads. When he returned, the car had gone. At 3.53am the car drove headlong into an articulated lorry. Dean was killed outright. The Claimant had somehow moved from the front passenger seat into the rear of the car. He survived the crash but sustained extremely serious injuries. He brings this claim for damages for those injuries and other losses arising out of the accident. Primary liability is admitted. Contributory negligence is alleged: (1) The Claimant knowingly allowed himself to be driven by Dean, whom it is alleged the Claimant knew or ought to have known was not fit to drive by reason of his intoxicated state: Owens v Brimmell [1977 QB] 859; (2) The Claimant did not wear a seat belt: Froom v Butcher [1976] QB 276. 3. It is trite law that the burden of proof rests with the Defendant. By order made on 16 July 2019, Master Cook directed that the issues of liability and causation be tried separately from the issue of quantum. This is the Judgment on those preliminary issues. The Evidence 4. Tragically, before the trial began, Aaron took his own life. Before he died he provided written witness statements to the solicitors for the Claimant and for the Defendant. 5. The Claimant is in a minimally conscious state and is clearly unable to give evidence on his own behalf. 6. The written lay evidence on behalf of the Claimant comprised: (1) Donald Campbell, Claimant’s father, dated 7 December 2017; (2) Aaron Brown, dated 3 December 2017 and 26 June 2018; Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 4 20. In his third statement he says: “I put his seatbelt on him whilst we were thinking about going back into the club.” He also repeated, verbatim, the passage in his first statement concerning the Claimant’s inability “to put his seat belt on for himself”. 21. Aaron signed his first statement in December 2017, about 16 months after the accident. The other two statements were signed in May 2018 and June 2018 respectively. There is no way to reconcile the conflicting accounts. Aaron does not in his second and third statements seek to address the inconsistency. It does not seem to me to be likely that Aaron’s memory of the night in August 2016 was significantly, or any, more reliable in December 2017 than in May and June 2018. 22. I do not attach much weight to the fact that Aaron has twice said he put the seat belt on the Claimant, and only once said he did not. It would be surprising if Aaron altered his account of this matter between May and June 2018. 23. On balance I consider it more probable than not, and I so find, that Aaron put the seat belt on the Claimant. It would have made sense to take that step to provide some degree of support for the Claimant as he slept. 24. Aaron and Dean then went back into to club. They continued to drink. Aaron thinks they remained in the club for about an hour. When they came out and went to the car, Aaron got into the rear offside passenger seat. The Claimant was still asleep or passed out. Aaron, in his second statement, says: “I can’t be sure but believe that Lyum was still wearing the seatbelt”. Mr Ross QC submitted that this is insufficient evidence to establish that the Claimant was wearing his seat belt. I have found that the Claimant was left in the car with his seat belt on. I see no reason to suppose that the Claimant woke up whilst Dean and Aaron were in the club and undid his seatbelt. I find that the Claimant was wearing his seat belt when Aaron and Dean returned to the car. 25. The car would not start. Aaron got out of the car to go back to the club to see if he could borrow some jump leads. Dean must have got out of the car to allow Aaron to get out of the rear offside seat. In his second statement Aaron says he thinks he was “in the club” for about 15 minutes. It is not clear if by that he means he was away from the car for 15 minutes or whether, given that the walking distance from car to club is five minutes, he was away for 25 minutes. Little if anything turns on that. When Aaron returned to the place where the car had been parked, it had gone. Aaron went home in a taxi. Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 5 The Collision 26. Dean’s car was driven head-on into an articulated lorry. The lorry was on its correct side of the road. It is probable that Dean had fallen asleep at the wheel, but it is not necessary to make a finding of fact on that issue. The collision site was approximately 9.3 miles from the club. The car had been driven towards Oxford, which is in the opposite direction to the location of the Claimant’s house. Given that the collision occurred at 3.53am it is probable that the car was driven away at about 3.30am or shortly thereafter, which corroborates the estimate of Aaron that he and Dean left the club at some point between about 3.00am and 3.30am; probably closer to 3.00am given that Aaron went back to the club to look for jump leads. 27. The closing speed of vehicles at impact was very high: (1) The speed of the lorry was between 43 mph and 45 mph; (2) The speed of the car was between 56 mph and 69 mph; (3) The closing speed was between 99 mph and 114 mph. 28. Dean was killed instantly. The forensic toxicology report prepared for the Coroner showed that: (1) Dean had used cannabis at some time before his death. It was not possible to determine when Dean had last used the drug. (2) However, the high concentration of tetrahydrocannabinol-carboxylic acid (THC-COOH) found in the post-mortem blood was suggestive of “heavy and/or regular use”. (3) Studies have suggested that impairment in driving can extend for up to 24 hours after the drug is used. (4) Ethanol (alcohol) was detected in the post-mortem blood sample. Post- mortem microbial action does produce ethanol, but typically less than 50mg/dl. The concentration of ethanol in the sample of post-mortem blood was 176mg/dl. The legal driving limit is 80mg/dl in “life blood”. (5) Various studies have demonstrated that impairment of driving ability is significantly increased when cannabis and alcohol is used together compared with their use alone. 29. Neither Dean nor the Claimant were wearing seat belts at the moment of collision. The Collision Reconstruction experts agree that the Claimant was most probably lying across the rear seats at the time of the collision. 30. They also noted very heavy loading on the rear of the driver’s seat as a consequence of the loading by the unrestrained Claimant. Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 6 31. The head and torso of the Claimant appear to have made contact with the rear of the driver’s seat. The Claimant’s Position in the Car 32. The question obviously arises: how did the Claimant come to be in the rear of the car? I accept that when Aaron left the car to go back to the club, the Claimant was still asleep and in the front passenger seat with his seat belt on. 33. Possibilities include: (1) The Claimant woke up and unilaterally, and voluntarily, decided to change positions in the car. If that is the case, he could have done so completely on his own or done so with the assistance of Dean; (2) Dean decided to move the Claimant into the rear seat. 34. If the Claimant changed position on his own, without assistance from anyone, he would have had to have performed the following manoeuvres: (1) undone his seat belt; (2) got out of the car; (3) moved the front seat forward; (4) got into the rear seat; (5) closed the front door from his position in the rear seat. 35. That seems to me to be unlikely in the extreme. Whilst I accept that the Claimant had been asleep in the car for a while, I find it to be unlikely that he could have sobered up sufficiently to execute those manoeuvres on his own. 36. It is far more likely, and I so find, that Dean assisted him into the back seat. 37. Can it be determined whether the change of position was the Claimant’s idea or the Defendant’s idea? I consider that it can. Dean had already allowed Aaron into the rear offside seat, got in himself, tried to start the car, failed, got out of the car and let Aaron out of the rear seat. It is probable that Dean moved the driver’s seat forwards to allow Aaron to get out, but I cannot rule out the possibility that Aaron moved the driver’s seat forward on his own, even though it is notoriously difficult for a rear seat passenger to accomplish this procedure. But it does not seem to me that anything turns on this. 38. At this point, Dean was out of the car. If he got back in, he would have to get out again when Aaron got back, move his own seat forwards again, allow Aaron into the back, move the seat back again and get in himself. 39. I consider it far more likely, and so find, that it was Dean’s idea to move the Claimant from the front passenger seat to the rear of the car. If he did that, Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 9 (3) The fact that a person is able to retain the information relevant to a decision for a short period only does not prevent him from being regarded as able to make the decision. (4) The information relevant to a decision includes information about the reasonably foreseeable consequences of- (a) deciding one way or another, or (b) failing to make the decision. 46. Inexorably linked to the issue of capacity is the Claimant’s state of awareness generally and specifically his knowledge of Dean’s level of intoxication. 47. The only lay evidence of the Claimant’s state of awareness and of Dean’s intoxication comes from Aaron. 48. There is no evidence that Dean drank anything before he arrived at Aaron’s house. In his second statement, Aaron says: “I cannot recall clearly, but I think that we all had a couple of drinks at my house before heading out.” Although the Claimant had been drinking already, if Dean did drink at Aaron’s house, the Claimant must have been aware of it. Given my finding that Dean and the Claimant arrived at Aaron’s at around 11.00pm and left for the club not later than 11.30pm, there would not have been much time for drinking at Aaron’s. 49. At the Moo Moo club, all three men were drinking. In his first statement, Aaron says they had at least three bottles of champagne and that Aaron bought “at least 20 shots”. He says that “Dean and Lyum would have bought more drinks”. In addition, he recalled that earlier in the evening “we had been drinking Tequila with Lyum”. 50. In his second statement Aaron says that they all had the same amount of alcohol to drink. He thought they had two bottles of champagne, shots, and brandy and coke. 51. The Claimant’s awareness of what Dean drank is limited to the time before the Claimant was helped from the club. After that, the evidence is that he was asleep in the car. He may have been aware that Dean and Aaron had left him and gone back to club, but there is no, or no reliable, evidence from which I can make any finding that he knew for how long they had gone or how much more each of them had to drink. 52. Aaron is a little inconsistent in his recollections of how much was drunk by the three men whilst they were together. However, whatever the true amount, it was clearly a lot, comprising, at the very least, champagne and numerous shots. Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 10 53. Aaron, in his third statement, says that as the Claimant was being put in the front seat: “There was only a very short conversation with him, getting him back into the car as he was in no fit state to talk and by the time we closed the door Lyum has passed out”. 54. By the time the Claimant was put into the front seat of the car, he had spent all evening with Dean and must have been aware that Dean had drunk a great deal of alcohol. 55. When Dean and Aaron returned to the car, the Claimant had been asleep for a time, probably for around an hour or so. I have already found that the Claimant was awake when Dean began the process of moving the Claimant into the back of the car. I must determine whether, on the available evidence the Claimant was: (1) able to and did consent to that change of position in the car; and (2) was able to and did consent to being driven in the car; and (3) was aware that Dean would be driving; and (4) was aware that Dean’s ability to drive was impaired by reason of the alcohol he had consumed. 56. The starting point is the presumption of capacity. Further, capacity is time specific and issue specific. It seems to me relevant that when Aaron headed back to the club the Claimant had been asleep for, as I have found, around an hour. 57. In my judgment the evidence of previous consumption of alcohol by the Claimant is insufficient to displace the presumption of capacity to consent to moving position into the back of the car. With specific reference to the functional test in Section 3 of the 2005 Act: (1) The information relevant to the decision is simple. It involved the Claimant getting out of the front of the car and getting into the back. I reject any proposition that the Claimant could not understand what was happening. (2) The process was continuous, so that there can have been no difficulty in retaining the information. (3) The use of that information must have been part and parcel of the process of moving. In my judgment the Claimant, at the very least, was probably aware of what was happening. There is necessarily no evidence of the Claimant objecting to the change of position in the car. Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 11 (4) Communication of the decision to assent to the proposal to move position is provided by the fact that the Claimant did in fact change position and the absence of evidence of any opposition. 58. If the Claimant had capacity to consent to a change of position in the car, then in my judgment he also had capacity to consent to being driven in the car. Having found that the Claimant must have known he was moving from the front of the car to the back of the car, I also find that this move is only consistent with the Claimant consenting to remaining in the car whilst it was driven away. If his intention had been to leave the car, before it was driven off, he would surely not have got into the back of it. 59. The Claimant knew that the car belonged to Dean and that he would be the only one likely to drive it. The available evidence does not point to the Claimant being incapable of being aware of that at the time he changed position in the car. 60. Lastly, the available evidence does not point to the Claimant being incapable of being aware of the amount of alcohol that Dean had consumed, or that such quantity would have impaired Dean’s ability to drive safely. The Claimant must have been aware of Dean drinking at Aaron’s house. He must have been aware of the amounts of alcohol consumed by all three men in the club whilst the Claimant was in the club. Consequently, I find that the Claimant was aware that Dean had consumed so much alcohol that his ability to drive safely was impaired. 61. The decisions made by the Claimant may well be characterised as unwise. Anecdotally, it is by no means unusual for people who have drunk alcohol to make unwise decisions. Late night on-line shopping for unwanted and unnecessary items; posting inappropriate messages on social media are but two examples of well documented examples of unwise decision making by persons who are under the influence of alcohol. 62. I am aware, of course, that when Dean did drive away from the club it was in a direction away from where the Claimant lived. I am unable to say why that should have been, but it does not seem to me to invalidate my conclusions on the Claimant’s capacity on the specific issues which I have considered. 63. The relevant case law is straightforward. The leading case is Owens v Brimmell [1977] QB 857. Having reviewed the authorities Watkins J said (pages 866G-867A): “… [I]t appears to me that there is widespread and weighty authority for the proposition that a passenger may be guilty of contributory negligence if he rides with the driver of a car whom he knows has Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 14 “74. In relation to the fourth allegation, in my judgment that is negatived by the Claimant’s state of mind, as I have found it to be. Whether as a result of the ongoing effects of the hypoglycaemic attack or the effects of the pre-existing brain injury or a combination of the two, the Claimant did not appreciate the danger he was in, in climbing the fence, just as he had not appreciated the position he was putting himself in when he cleaned his shotgun at Terminal 1 of Heathrow Airport. Just as a young child is not guilty of contributory negligence in running out into a road where the child is so young as not to appreciate the danger of so doing, so too where a person’s state of mind is such that, whether temporarily or permanently, they do not appreciate that they are putting themselves in danger and it cannot be said that they should have so appreciated. Otherwise, that would be to penalise a person for being ill or of unsound mind, and the law does not do that.” 73. It seems to me that the situations which Martin Spencer J had in mind did not include self-induced intoxication. His reference to the law not penalising “a person for being ill or of unsound mind” does not in my judgment include persons who have got themselves deliberately drunk. 74. It might be argued that the difference in approach lies in the distinction between non-feasance and mis-feasance, but at all events it seems to me to be thoroughly unattractive that a mildly drunk person might be guilty of contributory fault for making an unwise decision whereas a person who had deliberately consumed so much alcohol that they are unable to appreciate the foolishness of their decision is in a better position in law. This does not seem to me to represent the law as it applies to decisions whether to accept a lift from a drunk driver, where an element of objectivity applies. Failure to Wear a Seat Belt – the Law 75. The leading case is Froom v Butcher to which reference has already been made in a slightly different context. Lord Denning MR, in a judgment with which the other members of the Court of Appeal agreed, summarised his conclusions at pages 295G to 296F: “Whenever there is an accident, the negligent driver must bear by far the greater share of responsibility. It was his negligence which caused the accident. It also was a prime cause of the whole of the damage. But in so far as the damage might have been avoided or lessened by wearing a seat belt, the injured person must bear some share. But how much should this be? It is proper to inquire whether the driver was grossly negligent or only slightly negligent? Or whether the failure to wear a seat belt was entirely inexcusable or almost forgivable? If such an inquiry could be easily undertaken, it might be as well to do it. … In most of these cases the liability of the driver is admitted, the failure to wear a seat is admitted, the only question is: what damages should be Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 15 payable? This question should not be prolonged by an expensive inquiry into the degree of blameworthiness on either side, which would be hotly disputed. Suffice it to assess a share of responsibility which will be just and equitable in the great majority of cases. Sometimes the evidence will show that the failure made no difference. The damage would have been the same, even if a seat belt had been worn. In such cases the damages will not be reduced at all. At other times the evidence will show that the failure made all the difference. The damage would have been prevented altogether if a seat belt had been worn. In such cases I would suggest that the damages should be reduced by 25 per cent. But often the evidence will only show that the failure made a considerable difference. Some injuries to the head, for instance, would have been a good deal less severe if a seat belt had been worn, but there would still have been some injury to the head. In such a case I would suggest that the damages attributable to the failure to wear a seat belt should be reduced by 15 per cent.” At page 296 E-F Lord Denning MR said: “Under the Highway Code a driver may have a duty to invite his passenger to fasten his seat belt; but adult passengers possessed of their faculties should not need telling what to do. If such passengers do not fasten their seat belts, their own lack of care for their own safety may be the cause of their injuries.” 76. Mr Kennedy also referred me to J v Wilkins [2001] RTR 19 (CA) at [18] and Patience v Andrews [1983] RTR 447 in support of the propositions first that a court should not ordinarily step outside the suggested ranges and secondly that the court should not engage in speculating what injuries might have been sustained, but were not, if a seat belt had been worn. 77. The primary submission of Mr Ross is that the Claimant was so incapacitated through alcohol ingestion that he could not properly decide whether to enter the car, much less decide whether to activate a seat belt. Therefore, argues Mr Ross, it was the responsibility of Dean to ensure that the Claimant was wearing a seat belt before he drove off. 78. He referred me to Pasternak v Poulton [1973 1 WLR 476 and Hughes v Williams [2013] EWCA Civ 455, [2013] PIQR P17 in support of the proposition that in certain circumstances it is the driver of the vehicle that has the duty to ensure that the passenger is seat belted. 79. In Pasternak v Poulton the Plaintiff was the front seat passenger in a car driven by the Defendant which crashed by reason of the Defendant’s negligent driving. Neither was wearing a seatbelt. Kenneth Jones J held (pages 482H – 483B): Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 16 “In my judgment the duty to take reasonable care for her [the plaintiff’s] safety which he [the defendant] owed to the plaintiff involved not merely a duty to drive and to control the car itself with reasonable care and skill but also involved the taking of some step directed to seeing that the plaintiff wore the seat belt which was fitted to the car. What steps the driver must take depend on all the facts of the case but here, at the very least, the duty of care which the defendant owed to the plaintiff involved either demonstrating the existence of and the need for the use of a safety belt by simply wearing his own, or at least pointing out to the plaintiff the existence of the seat belt and explaining to her in only a very few words that it was there for her to use. He did, as he frankly confessed, nothing in relation to the wearing of seat belts either by himself or by his passengers. In my judgment in so conducting himself he was negligent.” 80. His Lordship held that in the circumstances the Plaintiff was guilty of contributory negligence in failing to wear a seat belt only to the extent of 5%. 81. It is stated in the head note to Froom v Butcher that Pasternack v Poulton was “approved”. However, in Madden v Quirke [1989] 1 W.L.R. 702, Simon Brown J (as he then was) was of the view that Lord Denning MR, in Froom v Butcher, had disapproved the relevant part of the judgment of Kenneth Jones J in Pasternack v Poulton. Having recited the passage in Froom v Butcher at page 296 E-F dealing with the Highway Code, Simon Brown J said this at page 708 B-E: “That approach is surely inconsistent with an unbelted passenger’s claim against the driver based upon the latter’s failure to encourage or insist upon the belt being worn. I refer, of course, as did Lord Denning MR, to passengers other than infants or patients. It seems to me moreover that the Court of Appeal there impliedly disapproved that part of the decision in Pasternack v Poulton … in which Kenneth Jones J had held that the driver’s ‘want of care operated not merely in the field of controlling and driving the car, but also in the field of failure to wear a seat belt, that is, in the very same field as that in which the plaintiff’s want of care alone had effect.’ The driver’s duty was there stated, at pp. 482-483, at the very least to involve: ‘either demonstrating the existence of and the need for the use of a safety belt by simply wearing his own, or at least pointing out to the plaintiff the existence of the seat belt and explaining to her in only a very few words that it was there for her to use.’ The plaintiff’s contribution in that, the first reported seat-belt case, was assessed accordingly at only 5 per cent. But of course that case concerned a 1971 accident and already by 1975 the Court of Appeal Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 19 (9) Following on from the last point, had the Claimant been restrained in the rear offside seat, the impact loads on the rear surface of the driver’s seat would have been less and the driver’s seat would have lain in a more rearwards position than was noted at the times that the engineers inspected the car. (10) The final point of agreement in the section of the joint statement headed “Points of Agreement” is important and I quote it in full (emphasis added): “We agree that, as a conventionally positioned rear seat occupant, restrained by a seat belt, [the Claimant] would have been exposed to the probability that his head struck the rear of the driver’s or front passenger’s seat, depending on where he was sitting.” 92. I accept that evidence. I have determined that the Claimant occupied the rear nearside passenger seat. As will become clear below, when considering the oral evidence of the engineers, I also find that had the Claimant been restrained by a seat belt in that position it is probable, and I so find, that his head would have struck the back of the front passenger seat. 93. There are further points of agreement, which are recorded in the section headed “Points of Disagreement”: (1) The effectiveness of a correctly worn seat belt would depend on the Claimant’s lateral position across the car. The offside position had the greatest potential to cause injury, whilst the nearside position had the least potential. “This is because the collision forces were greater towards the offside of the vehicle, due to the offset nature of the collision. The greater level of intrusion towards the offside of the vehicle would also have had a similar, but probably a lesser effect.” (2) The main stiff structures at the front of the car did not engage directly with the tractive unit. It was noted that this was a severe impact. Despite this, the engineers were of the opinion that if the Claimant had been correctly restrained, the severity of the forces applied to his body would have been reduced “to an unknowable degree”. There would have been a corresponding reduction in the rotational acceleration of the Claimant’s head, compared to a situation in which the entire front structures of the car fully engaged with the tractive unit at the same impact speed. (3) Further to the above, the car pitched forward sufficiently for the roof of the car to contact the front of the tractive unit. The rotational movement of the car comprised in the pitching forward of the car Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 20 “would have reduced the rotational acceleration of [the Claimant’s] head to an unknowable degree” compared to a situation in which the car remained approximately horizontal during the collision. 94. There were significant areas of disagreement. Some of those areas concerned the mechanism of causation of the Diffuse Axonal Injury (DAI) to the brain sustained by the Claimant, which were more fully explored in oral evidence and, in my judgment, largely overtook the contents of the joint statement. Other areas of disagreement are summarised below: (1) Mr Jowitt was of the opinion that even if restrained, the Claimant “would have been exposed to the potential for significant head contact injury”. (2) After referring to various studies, he concluded that the Claimant “may have suffered the same level of internal head harm as is recorded” (emphasis added). (3) Mr Henderson thought that if the Claimant’s head had struck the rear of the seat in front of him, the seat back would have flexed forwards under loading. He also noted that the rear of the seat was padded. These factors together would have afforded some protection to the Claimant’s head. Mr Jowitt agreed with the generality of the proposition, but noted that the impact performance of rear front seats had not been the subject of regulatory testing and was therefore unknown. 95. There was also a large measure of agreement between the medical experts recorded in their Joint Statement, although over a fairly narrow compass: (1) The principal question was: “had [the Claimant] been wearing a seat belt (properly fitted 3 point harness) at the time of the accident ... would he have suffered less severe injuries than he in fact suffered, principally, the devastating brain injury.” I agree with that observation. (2) It is likely that the massive deceleration which resulted from the impact was the likely cause of the DAI. (3) Such a decelerative force was likely to have been produced when the Claimant’s head had struck the solid structures within the car. 96. Areas of disagreement were: Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 21 Dr Allder (1) Even if the Claimant had been wearing a seatbelt, “it is likely … his injuries would not have been reduced”. (2) Even if the Claimant had been wearing a seat belt “he is likely to have suffered the head strike” resulting in the brain injury suffered by the Claimant. Mr Skinner (3) If the Claimant had been wearing a 3 point harness “his injuries would have been significantly less severe and that it was quite possible that he would not have suffered the devastating brain injury” (emphasis added). (4) The wearing a properly fitted seat belt “would have substantially reduced the decelerative force suffered by the Claimant and was likely to have prevented a head strike which was the cause of his brain injury”. 97. When compiling their reports, none of the experts knew that the Claimant was nearly six feet tall. They first learned of this fact during the trial. 98. In cross examination Mr Jowitt said that in his opinion it was “almost inevitable” that the Claimant’s head would have made contact with the seat even if he had been restrained. Mr Kennedy referred him to paragraph 3.47 of his report when he wrote: “If [the Claimant] was a restrained rear seat occupant, it is my view that he would have been exposed to a very high level of deceleration, and that his head might have struck the rear surfaces of the driver’s seat during the collision phase” (emphasis added). Mr Kennedy asked: what was the “might not have”? Mr Jowitt said that this might be the case if the passenger was a very short person, explaining that when he wrote his report he did not know the height of the Claimant. He made the point that at paragraph 2.18 of the joint statement he and Mr Henderson had agreed on the word “probably” as used in the passage already cited: “We agree that, as a conventionally positioned rear seat occupant, restrained by a seat belt, [the Claimant] would have been exposed to the probability that his head struck the rear of the driver’s or front passengers seat, depending on where he was sitting” (emphasis added). 99. There were questions about the front passenger seat. Mr Jowitt said that it was probably not properly latched from the start of the journey, and I agree with that. He was asked whether, if the Claimant had been a rear near side seat belted passenger, his head would have struck the front passenger seat. He said Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 24 111. On the issue of the force loads in this case, the engineers agreed that the crumple zone of the car was undamaged and had not been engaged. Instead, contact between the car and the tractive unit was with the stiff structures of the car, causing forces of much greater magnitude to be transmitted through the car. Mr Jowitt thought that the movement of the Claimant would have occurred within the space of one-tenth of a second. I accept that. 112. Mr Henderson was pressed on the issue of the extent to which wearing a seat belt would have reduced the seriousness of the injuries sustained by the Claimant. At paragraph 14.3 of his report Mr Henderson referred to the possibility of the Claimant’s head striking the rear of the front seat ahead of him. When he wrote that paragraph he did not know the height of the Claimant, and it must now be read in the light of the fact that Mr Henderson accepts that there would have been a head strike. He wrote: “The severity of the collision was such that [the Claimant’s] neck is likely to have flexed forward, possibly allowing his head to contact the rear of the set ahead of him. However, if contact did occur, the severity of any consequential head/face injuries is likely to have been much lower that the injuries he did suffer because most of his movement within the car would have been managed by the seat belt.” 113. At paragraphs 14.7 and 15.2(f) of his report he wrote that in his opinion “a correctly worn seat belt is likely to have been effective at reducing the severity of the injuries that [the Claimant] suffered”. 114. In cross-examination he accepted that he could not say what the nature of the injuries would have been likely to have been. He was asked if it was impossible to evaluate the differences. He said it was difficult to do so, and this applied to a head strike against the front passenger seat as well. Asked if it was possible to delineate between the consequences he said he could “not put numbers on it”. 115. He agreed that the forces generated in the collision were of a magnitude beyond tests and common experience and that he (and I think no-one) had any experience of a seat belted adult in a rear seat being involved in a collision with a delta-V and forces of a similar magnitude to those generated in this collision. 116. In coming to his conclusion that wearing a seat belt would have made a difference, even given that the Claimant would have suffered a head strike, he said he relied upon extrapolating his experience gained from investigating low speed impacts. He agreed he had no other evidence to support his conclusion. He could not say what forces were required to trigger a DAI in a passenger. Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 25 He could not “put numbers” on the difference a correctly worn seat belt would have made. 117. In re-examination he was asked what material he had relied on in deciding that a seat belt would have made a difference. He said it was based on his experience of what he had seen in the course of examining about 1,000 vehicles. He thought that rotational forces reduced towards the nearside of the car, although he had previously agreed that a possible sequence of events was the striking of the tractive unit, followed by the car moving backwards, then tipping up and then rotating. In my judgment, the forces generated by the events before rotation must have been considerable and would have been experienced by the person located in the rear near side passenger seat. 118. Although both engineers sought to assist me in the mechanism of the cause of a DAI, I found the evidence of the medical experts to be of greater assistance. 119. Dr Allder is a Consultant Neurologist, appointed as such in 2004 at the Plymouth Hospitals NHS Trust. He left the NHS in August 2015 and has since been employed by Re:Cognition Health in Wimpole Street, London. 120. In 1993 Mr Skinner was appointed as the first Consultant in Accident and Emergency Medicine at the John Radcliffe Hospital in Oxford. He retired from the NHS in 2011, but upon retirement he was appointed “Emeritus Consultant in Emergency Medicine, Oxford”. He continued to practice emergency medicine until 2016 when, as he says in his CV, he revoked his “Licence to Practice” with the GMC “after 41 years of continuous medical practice”. 121. Dr Allder and Mr Skinner have brought to this case different areas of expertise. 122. When in active clinical practice, Mr Skinner led a team that dealt with patients who had been involved in major traumas, including road traffic accidents. He and his team received information from the ambulance crews including, if known, whether a seat belt had been worn. The task was to read the wreckage and try to interpret what injuries there may be in order to stabilise the patient. He made it clear in his report (paragraph 10) that he was not a spinal orthopaedic surgeon or neurosurgeon, but an “emergency medicine specialist who deals with these sorts of cases in the earliest stages of their assessment, diagnosis and resuscitation”. 123. Dr Allder readily agreed in cross examination that he was not an accident and emergency surgeon or a neurosurgeon. As he put it, the acute stabilisation of trauma patients was not part of his work. He was asked by Mr Ross if he was Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 26 an appropriate expert for this case, given his lack of experience of trauma patients. He explained that medical professionals were becoming increasingly specialized, and that in terms of understanding the mechanism of the causation of DAIs “that is 50% of what I do every day”. 124. Dr Allder explained the mechanism of the causation of DAI by reference to a standing person who is hit on the head which something heavy. There are three types of strain put on the brain: (1) At the point of impact, the skull hits the brain. (2) As the head and neck are pushed away, the brain lags behind so that the skull strikes the brain. (3) The brain continues to move and is halted by the structures tethering the brain to the skull, but unless the force is perfectly linear, this causes a rotational force. 125. It is the shearing forces that cause the axonal damage found in DAI. 126. Dr Allder then explained that the same three forces were at play in a standing person who trips and falls the ground. 127. In this case, the Claimant was accelerated forwards very fast so as to hit the back of the front seat, where his head underwent a massive decelerating force. 128. Both Dr Allder and Mr Skinner agreed that it is the decelerative force that is the key component in the mechanism of injury. Dr Allder said that the deceleration is the critical factor. Mr Skinner said that “it is the deceleration that kills you” and “it is the deceleration that causes the damage”. 129. For Mr Skinner, the distance over which the deceleration took place is also important. He repeated the explanation given in his report concerning the difference in outcome between a crash into a tree by a motor cycle and a motor car, both at 60 mph. A motor cycle has no crumple zone, so the rider is thrown over the handlebars and decelerates from 60 mph to 0mph over about one inch (helmet thickness plus tree bark). The motor car has a crumple zone of around four or five feet, allowing a more gradual deceleration. 130. Mr Skinner said that if the Claimant had been wearing a seat belt there would have been a “ride down” distance such that the decelerative effect of the collision would have been reduced. 131. I see the force of the analogy. However, in this case, the crumple zone of the car was not engaged. Also the rear seat belts did not have pre-tensioners, unlike the front seat belts. Mr Henderson agreed that, depending on the amount of clothing worn, a pre-tensioned seat belt offers a greater degree of Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 29 Claimant. The evidence does not show that wearing a seat belt would have made a “considerable difference” such that the Claimant’s injuries would have been a “good deal less severe”, to use the words of Lord Denning MR in Froom v Butcher. 146. I accept the submission of Mr Ross that this was a unique accident generating forces outside anyone’s experience. It has been impossible to assess factors such as the deceleration rate, or the distance from the head of the Claimant’s hypothetically seat belted body to the rear of the front passenger seat. Indeed, it was not until the trial that anyone knew the Claimant’s height, and that in itself caused the engineers to conclude that there would have been a head strike. 147. I am unable to find that wearing a seat belt would have made any difference in outcome such as to enable me to make any reduction in damages by reason of the failure of the Claimant to wear a seat belt. There must come a point where the wearing of a seat belt does not make any difference to outcome, and it seems to me to be likely that such point was reached in this case. Degree of Contributory Fault 148. In Owens v Brimmell the degree of contributory fault on the part of the Plaintiff was assessed at 20%. 149. Mr Kennedy submitted that I should determine the degree of contributory fault at a higher level in this case. 150. In Meah v McCreamer [1985] 1 All ER 367 Woolf J (as he then was) assessed the Plaintiffs proportion of blame at 25%. The Plaintiff had been working as a minicab driver. After finishing work, he went to a public house and started drinking. The Defendant was already there and, as the Judge found “had clearly been there for some time before he arrived”. The Defendant then drove himself and the Plaintiff to a Country Club about 15 miles away. In evidence the Plaintiff said that he had left his own car behind because he knew they were going drinking. The Judge found that if the Plaintiff had not been affected by drink it would have been quite obvious to him that the Defendant was not in a fit state to drive. The quantity of alcohol in the Defendant’s blood was 143mg/dl. The reading for Dean was 176mg/dl, but I reject the submission made by Mr Kennedy in his skeleton argument that this is the relevant figure for comparison purposes. That figure has not been adjusted to take account of the post-mortem production of alcohol resulting from microbial action, typically less than 50mg/dl. It is possible, since we do not know how much alcohol was produced by microbial action, but it is equally possible that Dean’s reading was less if the microbial action alcohol was 33md/dl or more. Approved for handing down Lyum Campbell v Advantage Insurance Co Ltd 30 151. It seems to me implicit from the judgment of Woolf J that the Plaintiff, when he left his car behind and went to the club in the Defendant’s car, that the Plaintiff was intending to be driven back by the Defendant. 152. In Stinton v Stinton and The Motor Insurer’s Bureau [1993] P.I.Q.R. P135 Simon Brown J (as he then was) assessed the contribution at one-third. The Plaintiff and the first Defendant driver were brothers. The driver was uninsured, hence the involvement of the MIB. The brothers had arranged to go to a working men’s club for a game of snooker. They drank moderately between about 7.30pm and 10.00pm. Then they went to a night club, arriving at about 11.00pm and staying until about 3.00am. The Judge was unable to make a finding concerning who had driven the car thus far during the day. The Judge found that the case “involves blameworthiness on the passenger’s part to the greatest extent possible, short of direct participation in the driver’s actual performance”. 153. Once more it seems to me implicit in the judgment that the Plaintiff had intended all along to be driven home by his brother. The two men had also been in each other’s company for the entire time that they had been drinking. 154. In this case, there is no evidence that there was an earlier agreement that Dean would drive the Claimant away from the club. Had it not been for the fact that the Claimant was put into the front seat of the car by Dean and Aaron it is quite possible that he would have gone home by taxi. 155. The Claimant must have known how much alcohol Dean had drunk up to the point where the Claimant was walked from the club to the car. Thereafter, he cannot have known how much more Dean had drunk. There is no evidence that the Claimant knew for how long he was left alone in the car whilst Dean and Aaron continued drinking in the club. There is no evidence concerning the Claimant’s awareness of any behaviour exhibited by Dean during the process of the Claimant transferring from the front of the car to its rear. 156. Having regard to those matters, this is not a case where the Claimant and Dean were together for the entire duration when Dean was drinking. Further, it is likely that the decision of the Claimant to allow himself to be driven by Dean was taken without a great deal of thought, although I have found that the Claimant had capacity to, and did, make this decision. 157. In those circumstances it seems to me that contributory fault on the part of the Claimant is less than that found to be appropriate in the two cases relied upon by Mr Kennedy. In my judgment, the appropriate degree of contributory fault on the part of the Claimant is 20%.
