Ah. Notes taken contemporaneously with the interview aren't necessarily entered on the GCMS system that same day or even immediately after, based on what I have read on appealed cases. The 6 week difference between the interview date and the date when GCMS entries of the interview notes were made may have been merely a procedural delay.
The problem is, there is her version of what took place at the interview, and there is your husband's version. You should be aware that the appeal judge will always prefer her version (the GCMS notes) to his (which is only verbal), unless you can directly prove that she was NOT a disinterested (objective) third party. The assumption is that she will neither gain an advantage nor be at a disadvantage by refusing or allowing his application, and therefore she will be considered in the right unless you can definitely show she isn't.
