So Garland can kill the budget and hence the chance for prosecutions come October?
In theory, the AG can kill it at any time if he really wants to.
The Special Counsel is sort of independent, but still is supposed to report periodically to the AG and the AG retains the power to revoke it at any time.
The power delegation is a bit complicated. Technically, the delegation does not rely on the Special Counsel regulation but merely makes reference to it.
This regulation is legally flawed, however it has been upheld by the courts in political decisions with patently bad legal reasoning.
If the Special Counsel regulation were to be struck down by an honest court, Barr’s original delegation to Durham would still survive and he crafted it with this in mind.
The delegation authority even assuming invalidity of the Special Counsel regulation also allows the AG to terminate the Special Counsel if he so chooses.
