Well, we both suggested that he could find out if the person in question told him.
If perotp has been sued for defamation over calling the disability fraud, he should have kept his mouth shut until he actually had some kind of proof. If he gets into trouble about it now, he's going to have to hope that a court is willing to order it.
People do have a right of medical privacy.
Medical records can be, and are, subpoenaed for use in a court action.
I agree that, IF the question asked by perotp has anything at all to do with defamation - and was not just placed in this section of the forum due to confusion over what defamation actually is (which is not an uncommon occurrence
) - it would be nice if perotp returned to fill us in on some details.
If a report on fraud or suspected fraud was made to the Social Security Administration (perhaps using the SSA Hotline), this type of communication would be privileged (although the privilege is a qualified one, subject to defeat upon a showing of actual malice). It would be unprivileged false statements of fact that potentially could support a defamation claim.
