One of the benefits, absolutely, is the fact that it's easy to get everyone in the same place at the same time. People don't necessarily have to travel from far distances.
One of the other benefits we hear from judges is the ability to see everyone's faces at the same time. Often a piece of evidence is heard, and the judge is trying to look in various places in the courtroom to gauge the reaction of the parties, to watch the witness or the accused person. This allows an opportunity to see the whole room. Those are the benefits.
The disadvantage is that we don't know what's happening behind the scenes. There may be cases—and we've certainly seen examples in the U.S.—where a witness is testifying, and the accused person is in the next room coaching them.
We do have some concerns about privacy and about whether or not the integrity of the system is being undermined in some cases. However, I think there are lots of advantages to focus on.
