A clear illustration of SD1's unreliability emerges from his shifting account regarding the Email. His position evolved repeatedly during the course of cross-examination — moving from an assertion that he "didn't receive" the Email, to claiming he "didn't see" it, and finally to saying he "didn't open" it — as reflected at RA1, pages 237 to 238. This pattern of fluid, self-serving adjustments underscores the instability of his evidence and reinforces the learned SCJ's finding that his testimony could not be safely relied upon. 11PPDid you receive or did you not receive?12SD1No, I didn't receive.13PPThat's your answer, you're not changing your answer?14SD1No, not changing.15PPSo it's not that you don't remember receiving it, but your answer is you didn't received?17SD1I don't get.18PPSo you answer, you are saying, you are not saying that you don't remember receiving, you're saying affirmatively you did not receive this email?2021SD1I didn't see it.1PPNo, no, you said you did not receive it?2SD1I didn't open it.
