Yes, that has been discussed to some extent here. We have exactly the same rule prohibiting revelation of anything that was said or done in the jury deliberating room.
In relation to counselling, the approach here is that there's confidentiality between therapist and patient. That's generally seen to cover the issue. It comes up in relation to the Samaritans as well. Of course, with the Samaritans that's a completely confidential discussion. The individual Samaritan will never know the identity of the person calling, and the person calling will never know the actual identity of the Samaritan. In effect, the issue of breaching disclosure that could be prosecuted wouldn't actually arise in either of those instances, because they're covered by confidentiality.
The only exception we have at present to the prohibition on discussing what happens in the deliberating room is for the purposes of an investigation into any misconduct that might have occurred on the part of the jury. Until the recent act, that was also covered, so the court was actually prohibited from inquiring into possible misconduct on the part of the jury.
