Police Reform and Social Responsibility Bill

I wonder if the noble Lord could help me on one point. As an experienced criminal practitioner, as he rightly describes himself, he is well aware that there are two elements in the code for Crown prosecutors. One is the test as to the adequacy of the evidence and the second is the public interest. Both have to be satisfied before a prosecution takes place. I note that in the amendment tabled in his name and that of the noble Lord, Lord Macdonald of River Glaven, there are two parts to this test. One part of the test, in proposed new subsection (4AA)(a), applies when there is enough evidence to be satisfied that there is a realistic prospect, so in that case there needs to be a consideration of the public interest. In the second test, in proposed new paragraph (b), which is where there is not enough evidence, there is no reference to the public interest at all. That is probably the most likely situation—that there is not enough evidence at that stage to know if there is a realistic prospect—so why does the public interest not come into his amendment at all, even though he has been addressing it on the basis that it is to replicate the current system, which requires the public interest to be considered?
