50 This demonstrates that an appellate court may infer from the express findings of a Judge, who has given adequate reasons, that he or she has rejected evidence inconsistent with those findings. The trial Judge referred to the relevant evidence of Mr Cooper and could only have come to the decision he did if he rejected it. An appellant must establish that the judgment appealed from was wrong (Warren v Coombs (1979) 142 CLR 531, 539), and will give respect and weight to the trial judge's conclusions (ibid 551). In an appeal from the exercise of a judicial discretion Lord Wright said that an appellate court will make every reasonable presumption in favour of upholding the judge (Heyman v Darwins Ltd [1942] AC 356, 388). In my view this was the approach adopted by McHugh J in the passage last quoted, and in my judgment it requires this Court to conclude that the Judge rejected the evidence of Mr Cooper that Elton had admitted that he was the driver of the bike.
51 The President has concluded that the Judge's use of the presumption of continuance was affected by legal error because he thought that the unequivocal evidence was needed to displace the presumption. I am not able to read the passage from the Judge's reasons quoted by the President in this way. In my view the Judge was simply commenting on the state of the evidence, and recording his finding that the evidence given by Mr Cooper about the admission by Elton was not unequivocal, and he could not safely rely on it. The passage in the cross-examination of Mr Cooper quoted above entitled the Judge to find that his evidence was not unequivocal. I do not read the sentence in question as dealing with the presumption or the evidence required for its rebuttal.
52 The President also holds that the Judge's use of the presumption involved circular reasoning because it depended on his acceptance of Elton's evidence that Carian was driving until shortly before the accident. However the finding that Carian was driving the bike around the vacant block also attracted the presumption, and Elton's evidence to this effect was corroborated by Bobby Jones. The lapse of time and the distance travelled after the bike was driven on to the road were short and do not rebut or materially weaken the force of the presumption.
53 I agree that the presumption does not have a higher status than other evidence and that it must be weighed against the accompanying facts. Its effect is that the existence of facts at one point of time is evidence of their existence at a later point of time. See Cloverdell Lumber Co v Abbott (1924) 34 CLR 122, 137-8 per Isaacs J.
54 I am unable, with respect, to accept that it is "a rational method of weighing the strength of two competing pieces of evidence". Its primary function is to fill a gap in the direct evidence.
55 In the present case there is such a gap because Elton said that his last memory some two hundred metres before the accident was that he was riding pillion, and Mr Cooper said that Elton admitted after the accident that he was the driver. There is no direct evidence of the identity of the driver at the time of the accident. As I read the Judge's reasons, he did not rely on the presumption in coming to his decision to reject the evidence of Mr Cooper. He simply found that his evidence on this question was not unequivocal evidence on which he could safely rely. He then turned to consider Elton's evidence that he was the passenger shortly before the accident, and found that this was reliable "using as an aid the presumption of continuance" (emphasis supplied). In my opinion this was a proper use of the presumption which did not involve giving it a higher status than other evidence. Elton's evidence was that he was still the passenger shortly before the accident and the presumption could operate for the rest of the journey until the collision.
56 The Judge found that Carian was driving the bike around the vacant lot. Some short time later, and 3 to 4 kilometres away, there is an accident. Unless there was a change of position in the meantime, Carian was still the driver. He was the more experienced driver and the more adventurous. He alone had driven the bike on private property while Bobby Jones was watching and conditions were safer than on a public road. If Elton did not ask, or was not allowed, to drive the bike on private property, one could infer that he would not attempt or be allowed to drive it on the road. There is nothing in the evidence of the events at the Jones's home to suggest that Carian would have wanted to stop on the road and change places with Elton. The presumption of continuance operating on the Judge's finding that Carian was driving the bike on the vacant block can therefore "aid" Elton's evidence that Carian was still the driver two hundred metres or so before the accident.
57 Regrettably, I am also unable to agree that the location of the bodies and the bike after the accident support an inference that Elton was the rider. Mr Cooper identified the tree that the bike hit by markings on the bark. There was a pedal mark a foot above the ground. More bark was missing about a metre from the ground on the right hand side of the tree where it looked as if the handle bar had hit it. The third mark was half a metre higher in the middle of the tree (black 69).
58 Bobby Jones's statement to the police (blue 91) records that he and his father collected the damaged bike the following day. The left and right foot pegs were smashed, the left side of the handle bar was bent, and the right side was grazed. About a week later they collected the helmets. The blue helmet that Carian had been wearing had bark on its left side. The helmet that Elton had been wearing had a crack at the temple height all the way around the back, but there was no sign of any bark.
59 It seems therefore that Carian's head hit the middle of the tree about 1½ to 2 metres above the ground. This would explain why, according to Cooper's plan, his body was lying close to the tree to the east of it.
60 Elton on the other hand missed the tree and travelled further up the road beyond the bike. The rider would have been closer to the tree when the collision occurred and, it seems to me, more likely to hit it when thrown from the bike. The passenger was further back and since the left handle bar took the major impact he could have been thrown off to the right with a catapult action and finished further away in the centre of the road.
61 No expert was called to give evidence on the inferences which could be drawn from the damage to the tree, the bike, and the helmets and the location of the bodies and the bike after the accident. If inferences are open on the evidence at all, those outlined above appear to be at least as likely as those referred to by the President.
62 In my opinion for these reasons the appeals by Carian and others in the same interest fail and should be dismissed with costs.
63 FITZGERALD JA: The circumstances giving rise to this appeal and the competing considerations are set out in the reasons for judgment of the other members of the Court.
64 The trial judge held that there was "no unequivocal evidence … to base a finding that Elton rather than Carian was in charge of the bike" and that there was "evidence which….. indicates that Carian was in control when the motor cycle struck the tree…". The only direct evidence Carian was in control was Elton's testimony. I consider that his Honour's finding that Carian was in control when the motorcycle struck the tree was based on Elton's evidence, which his Honour described as "reliable, using as an aid the presumption of continuance". I therefore agree with Handley JA that the trial judge accepted Elton's evidence that Carian was in control when the motor cycle struck the tree.
