In relation to the destruction of material ...
In relation to 'special procedure material' under PACE 1984, i.e. material (documents etc.) held by a party (e.g. a bank, accountant, whatever) under a duty of confidence, this was only obtainable by an investigator (constable etc) under a Production Order from a Circuit Judge. When making an application for a PO, notice was given to the holder of the material so that they could appear before the judge to argue the PO if they wished. The notice always pointed out to the holder of the material that - having been put on notice about the material - the material was therefore protected from destruction etc. under the law.
My point is this. Lawyers know about this sort of stuff. They will be very well aware of the general notice given by HHJ Goddard even if a specific notice was not served on WTBTS/IBSA UK (and I don't yet know whether a notice was served or not, perhaps WT was too small to be included). But an admitted Solicitor or a Barrister will have no excuse whatsoever.
I suspect that right now there are frenzied communications going back and forth between UK and US (just as I;m sure there were similar communications between Australia and US during the ARC hearings).
We all saw (and the world has seen) what a complete horlicks the WT made of the ARC hearings. The current climate in the UK regarding historic abuse does not bode well for the WT if it continues to obfuscate. I, for one, wouldn't want to be an elder hung out to dry for my actions - or even for shredding my notes.
