Rumet and others,
We are dealing with EU legislation here, which is legally binding. It does however allow for this process and as such no law has been broken.
However as the intersted parties note the Lord Advocate showed no evidence as to why the data should be handed over other than to state that this was the best way for their experts to decide if and whom to prosecute.
Taken to its logical conclusion one could argue that this would be the same in all accidents and incidents, hence why I belive we will see a lot more cases like this.
I am quite shocked as to how little weight was given to the concerns of the interested parties as to how future investigations would be adversely affected. (As well as the concerns expressed in EU legislation precisely about this issue).
