18 GCA § 89202: When may Rescind.

A party to a contract may rescind the same in the following cases only:

1. If the consent of the party rescinding, or of any party jointly contracting with him, was given by mistake, or obtained through duress, menace, fraud or undue influence, exercised by or with the connivance of the party as to whom he rescinds, or of any other party to the contract jointly interested with such party;

2. If, through the fault of the party as to whom he rescinds, the consideration of his obligation fails, in whole or in part;

3. If such consideration becomes entirely void from any cause;

4. If such consideration, before it is rendered to him, fails in a material respect, from any cause; or,

5. By consent of all other parties.
