There has been discussion on DS over the adjectives Masipa used to describe Pistorius' evidence and how she never actually said 'unreliable'. That's true, but she used some that are just as damning, if not more so.
In the legal appeal, it does not matter whether she used the word.
This is the sort of wormhole that laypeople love to jump down. :-D
Rather the question is whether it was proper for Masipa to rely on his evidence. Is he a "reliable" witness. It's a legal question.
To borrow a phrase from Chess - there is a "main line" of the case that Nel was following.
The "main line" is what you would expect any seasoned prosecutor to focus on.
OP's only defence is the mistake. Therefore the critical question is how did the mistake happen?
All that matters is those crucial seconds when Reeva goes from the bed to the bathroom.
The crime scene photos prove OP was lying about these crucial seconds. The Judge found he was a bad witness and lied.
Therefore according to an orthodox approach, OPs evidence on this point should be rejected "In Toto"
Therefore there is no "reliable" evidence that there was a mistake - and rather the situation speaks for itself.
This is what Nel is getting at with his argument and discussions about what is "reliable"
But instead the Judge essentially held that the mistake must have happened some other - yet unknown - way. Which the accused chose not to tell the court.
This is legally improper - as it effectively amounts to wild speculation
Again this is what I have said many times that I agree with Nel - the timeline was essentially irrelevant to a finding of murder.
The crime scene photos prove guilt because the evidential burden was on the accused and he did not advance reliable evidence.
