Don't quote me here on the Australian Regional Commission. But I think it was a lot to do with the JW policy of the 2 witness rule to the event.
Should someone come forward to the authorities about a ''child abuse'' scenario, normally 2 witnesses should have witnessed the event. If no such 2 individuals seen this, the case is dead in it's tracks. I'm not sure exactly, but the courts have examined this in Australia as this as being constitutional. Like I said, don't quote me here, but the courts may the WT's examined for this.
It was this argument that the Society of the WBTS is making the Elders destroy evidence on a lot of cases. ESPECIALLY, when it comes to child abuse molestation allegations.
Maybe someone could clarify this, if I'm not correct on the subject. Very complicated, deep issue.
