Question juridique clé
Whether the settlement agreement was voidable for essential mistake regarding orthopedic injuries
Solution extraite
The agreement could be avoided if the alleged orthopedic defects were truly substantial and had been assumed away by both parties as a necessary factual basis.
Motifs extraits
Medical uncertainty that was part of the compromise cannot justify mistake, but a shared incorrect assumption about an uncontroversial factual basis can. The lower court had not yet clarified whether the new orthopedic findings were correct.
