Canon 932

1. An act placed because of extrinsic force brought to bear

upon a person, which the person was not in any way able to resist, is considered null. 2. A juridic act placed because of

grave fear, which has been unjustly inflicted, or because of

fraud is valid unless the law makes some other provision; but

such an act can be rescinded by the sentence of a judge, either

at the instance of an injured party, or that party's successors

in law, or ex officio.
