I don't think the provisions themselves are what would enhance or cause additional delay. It's the fact of the police using complex investigational techniques in ongoing investigations that sometimes themselves take years and generate a great deal of documentation, whether inside here or outside, or whether these provisions exist or not, that is an issue. Complex investigations create a great deal of information.
That information, as you referred to earlier, is subject to the rules in Stinchcombe and broad definitions of relevance that the courts have put in. Certainly, that is an issue. It is the exact issue that you raised, that when you have this amount of information, the requirements of conveying it to the defence further to the disclosure obligation sometimes has taken a great deal of time.
I'm not sure it's one that is caused by these provisions or made worse by these provisions, but yes, certainly it is an issue in the justice system.
