The trial judge did not err in dismissing an application for recognition and enforcement of a judgment rendered in Florida condemning the respondent, as guarantor, to repay a loan of money; that judgment would have the result of giving effect to the waiver of a party to invoke any cause of nullity of the contract, including fraud by the other party, even though the waiver itself may have been obtained by way of this fraud, which is contrary to Quebec's domestic public order (art. 3155 (5) C.C.Q.).
