58 The Tribunal finds his evidence to be inconsistent in this respect also. At one point, he said he was driving the forklift at the relevant time. Later, he said it was turned off. He also said he was picking up bits of timber, which suggests that he was not sitting on the forklift at all. If Mr Falzon was working on the forklift at the time, and its engine was turned on - as he said originally - it seems unlikely that he would have overheard a private conversation between two men standing 8 to 10 feet away over the sound of a 'car engine', unless they spoke loudly. On the contrary, he gave evidence that Mr Hosking was chatting 'in a normal speaking voice'. In the result, it is unclear whether, at the point when the relevant words are alleged to have been said to Mr Vagg by Mr Hosking, Mr Falzon was working on the forklift, or its engine was on. It is also unclear why, if Mr Falzon could indeed hear the conversation clearly as he said, he was able to hear only two words of it, and not the remainder.
