I think it is an important point too that Relationships Australia are the ones technically fighting it. I want to believe that RA and the counsellor are just doing it because trust is a massive thing in counselling sessions with clients. And IMO their reasoning is that future clients may be less likely to open up if there was a risk that this type of scenario (court subpoena) could happen to them.
But here's the thing - this exception to confidentiality has been around for a very long time. Clients (should) are always told that this can happen. Of course, those clients who want to hide something out of fear of it coming out in a court of law will hide it, regardless. I haven't worked for RA, but I would assume they would have documentation and standard forms that clients fill out. This would suggest to me that GBC and Allison both were aware of this exception to confidentiality. Given a murder has occurred, I find it astounding that RA are still challenging this.
I made a post a while back about objective versus subjective case notes - I am really wondering if this could be a reason for this stubborn fight. Maybe some 'observations' or details were included in the notes that do open the counsellor up for quite intense scrutiny. And let's not forget the counsellor more than likely has a supervisor or superior at RA who would have some responsibility in the management of this case.
All just my opinion and just trying to understand the mechanics of this.
It would be interesting to know if RA has had previous subpoenas (which I am almost certain they would have), and how often they have fought so much to not comply. If this is the norm for RA to fight subpoenas, or just this one.
