In terms of consequences, I find it very difficult, to be quite frank, to envision a consequence, unless we're talking about perjury--in other words, if the member is actually deliberately, wilfully lying about the matter. An honest mistaken belief wouldn't be sufficient to meet a perjury charge, so it is difficult to see exactly what a sanction would be here, unless the member was actually, to be vulgar about it, lying.
