Another addendum to the elders manual is they are not to pursue judicial action against people who threaten suicide.
Tell your sister to write a letter saying that the very thought of such a meeting makes her feel suicidal and she is going for therapy and will let them know how she is.
(dont ever get back with them)
OR - if your sister happens to be seeing a therapist currently, have the therapist write a letter stating that the person is "too fragile" for this meeting at the present time.
I know someone who did this - worked like a charm.
