Let me understand the question. A complaint is made, and the letter in reply says.... It must set out the reasons why it's being rejected. Our policy requires that the reasons be set out in the letter.
Now, if one of the reasons is that we don't have enough evidentiary foundation for this, and you have more information or you can get more information, then you may wish to write back and tell us that you have something stronger to support this, or ask us to bring it to the attention of the commissioner to ensure that this has been properly considered. These are normal responses you might make.
I mean, we're evidence-driven. If we can make a case, we'll make it. If we can't make a case, then we are precluded from addressing the problem.
