Does mental illness count as a "sudden affliction" as defined in Roberts? Defendant was involved in two automobile accidents in fairly quick succession. The plaintiffs were involved in the second accident. The traffic report stated that defendant engaged in “bizarre” behavior before and after the collision with the plaintiffs. Defendant stated that she had little recollection of either accident. She claimed that she had no control of her actions, and believed that she had “wigged out” or “freaked out” at the time. She also claimed a family history of mental illness. Unrebutted medical expert evidence described the defendant as suffering a “[s]udden, unanticipated onset of mental illness” shortly before colliding with plaintiffs.
