There are important aspects of an international sales contract that are not regulated by the CISG, and one must rely on and/or consider domestic law. These include the following: CISG is not concerned with the VALIDITY of the contract, its provisions, or any usage. This means that in order to examine the capacity of the parties who entered into a contract, or to determine whether a party was induced into signing a contract by fraud, domestic law is going to be looked upon by a court, should a controversy arise. CISG excludes questions on the effect of PROPERTY or TITLE. As such, a third party who claims to have an interest in the goods that are sold, is going to have to rely in domestic law to find relief. Buyer is also going to have to look upon that area of domestic law which governs his situation regarding that third party who could claim a “better” right in the goods sold. The CISG does not apply to the LIABILITY of the seller for death or personal injury caused by the goods to any person. A serious question is indeed the case of torts law and liability. Like we said earlier, torts law in Mexico differs quite a lot from that of common law jurisdictions (such as Canada, the USA, England, etc.) and, therefore, should be considered.
