That's a really tough question to answer. It depends how many times the orders are changing.
Judgment is always needed when you apply exemptions. You want to make sure that the guidance is comprehensive and clear enough, so that border service officers, when they each apply their own judgment lens to it, they're doing so in the most fair and consistent manner.
That's why better supervision to make sure those judgments were being applied consistently is what was needed. We also recommended some additional control. Really, it's relooking at, any time a new order is issued, whether you need to clarify the instructions that were given. The frequency depends on how many times an order would change the guidance that you already have out there.
