Investigation of Women Religious

At least several MOJ posts in the last two months have addressed the Vatican investigation of women relgious in the United States.  I've tried hard to look at this in the best possible light, which I confess has not always been easy.

However, whatever one thinks of the investigation of the Leadership Conference of Women Religious and of religious orders in the US in general, what justification is there for saying the sisters will not be allowed to see the final reports that will submitted to the Vatican?   (See, e.g., here.) Even if one feels some sisters are overreacting in their opposition to the investigation, it is hard to argue that they don't have a legitimate gripe about not getting to see what is being reported about them.
