It's always a matter of construing the statute to determine the appropriate level of delegation.
But on the delegation of authority, there are a host of things that require Attorney General consent or authorization that didn't occur as a result of this act but have been of long standing.
The deskbook sets out which level is appropriate in each case and reflects an assessment--ultimately a decision by the Attorney General, who is the one who authorizes the deskbook--that this level is the appropriate one. But the Attorney General always has the ability, even under this legislation, to intervene or take over a prosecution, or issue a directive.
