If
Matthew Best is to be believed, Dr Shoo Lee's evidence
"was not allowed to be presented at appeal".
Firstly, it is relatively inexpensive to submit written evidence at a trial. The defense had the opportunity to submit Dr Lee's evidence in the form of an affidavit. They CHOSE not to do so.
As to the appeal, see my
post no. 207, where I stated the four criteria for evidence to be admitted at appeal that was not admitted at trial.
"4. There needs to be a reasonable explanation for why it was not introduced at trial."
"Flying Dr Lee over from Canada would have been really expensive, and beyond the limit of the resources available to my client" is the sort of reasonable explanation that the court would normally be willing to accept.
The defense CHOSE not to make this argument. They never even tried.
I do not doubt her guilt either.
