I would like to add something if I may.
The Quebec Bar intervened in R. v. St-Onge Lamoureux in 2012. At trial court, it presented expert evidence to show that there were 10 possible errors or manipulation errors related to the internal operation of the machine. I am not familiar with all the technical details of the machine's operation, but I remember very well that the Supreme Court found in its decision that there were nine possible errors and that it was very much inclined to state that the documents must be disclosed.
We could discuss this in another place, but under the Canadian system it is preferable to acquit nine guilty persons than to convict one innocent person. Assuming that the machine is accurate and reliable and reducing the volume of information to which the accused is entitled increases the possibility of one day convicting an innocent person.
