What is the test for the use of facial recognition technology at a jury trial?

In R v. Lyons,[6] La Forest J., writing for the majority, stated that, “at a minimum, the requirements of fundamental justice embrace the requirements of procedural fairness.” He went on to say, however, that the entitlement to procedural fairness does not entitle the accused to “the most favourable procedures that could possibly be imagined” (Lyons, at para. 114). In my view, the proposal here was fair. The technology used would ensure that the jury, the accused, and the counsel involved all had an excellent view of the witness.
