You have an absolute right to ask the claimant(s) questions pre - award, based on S14, which says that:
(1) On a claim for a tax credit the Board must decide:
(a) whether to make an award of the tax credit, and
(b) if so, the rate at which it is to be awarded.
The claims which you receive for examination pre-award will be
those where no decision has yet been made because they are
considered too high a risk to pay without obtaining further
Your role is to ask the questions that need to be answered before a decision on the claim can be made.
