That's interesting. I never knew that.
I suspect that lefevbre's denial he signed the Documents was an example of psychopathic pseudology. Or, maybe the onset of dementia. In any event, I doubt he intended to lie. I think, over time, he became delusional and began to think he really didn't sign the Documents he later repudiated.
To my way of thinking, that places his behavior in the best possible light because any and all psychopathological delusions would render one not culpable for the, objectively, serious sins he was engaged in
