OP, if I understand you correctly, you are the company CFO, yes? As in executive level, yes?

So why are you asking such a serious question here to people who clearly do not have all the details of the matter?

Why instead are you not having this discussion with someone at the executive level within your company who's responsibility is to oversee the HR department? For example someone director level or higher?

You have two issues here. One is you do not trust your HR manager is competent, two, you have a specific matter that requires attention and the information to arrive at a correct course of action is conflicting. Sounds to me you need to have a talk with someone at your level within the company.....
