2. Viada and Blanco are best friends. In July 2024, Blanco sold to Castan a parcel of land registered in Viada’s name. Blanco signed the deed of absolute sale in behalf of Viada and pretended as his agent. In August 2024, Viada executed a special power of attorney (SPA) authorizing Blanco to sell the identical parcel of land. Blanco executed a deed of absolute sale in favor of Sanchez Roman who was aware of the prior conveyance of the same land to Castan. Thereafter, Castan learned of the subsequent transaction between Blanco and Sanchez Roman. Castan then filed against Sanchez Roman an action for annulment of sale. Castan argued that Sanchez Roman is in bad faith because of his knowledge of the prior sale. Sanchez Roman countered that the sale between Blanco and Castan is void for lack of Viada’s consent. Castan replied that the subsequent issuance of the SPA to Blanco ratified any defect in their transaction. Who between Castan and Sanchez Roman has a better right over the parcel of land? Explain.
