Required Diligence of a Blind Person
The heirs of Francisco argue that the Court of Appeals erred when it ruled that Francisco was liable to CBCI because he failed to exercise the diligence of a good father of a family when he bought the diesel fuel. They argue that since Francisco was blind, the standard of conduct that was required of him was that of a reasonable person under like disability. Moreover, they insist that Francisco exercised due care in purchasing the diesel fuel by doing the following: (1) Francisco asked his son to check the identity of Bacsa; (2) Francisco required direct delivery from Petron; (3) Francisco required that he be named as the consignee in the invoice; and (4) Francisco required separate receipts from Bacsa to evidence actual payment.
Standard of conduct is the level of expected conduct that is required by the nature of the obligation and corresponding to the circumstances of the person, time and place.25 The most common standard of conduct is that of a good father of a family or that of a reasonably prudent person.26 To determine the diligence which must be required of all persons, we use as basis the abstract average standard corresponding to a normal orderly person.27
However, one who is physically disabled is required to use the same degree of care that a reasonably careful person who has the same physical disability would use.28 Physical handicaps and infirmities, such as blindness or deafness, are treated as part of the circumstances under which a reasonable person must act. Thus, the standard of conduct for a blind person becomes that of a reasonable person who is blind.
We note that Francisco, despite being blind, had been managing and operating the Caltex station for 15 years and this was not a hindrance for him to transact business until this time. In this instance, however, we rule that Francisco failed to exercise the standard of conduct expected of a reasonable person who is blind. First, Francisco merely relied on the identification card of Bacsa to determine if he was authorized by CBCI. Francisco did not do any other background check on the identity and authority of Bacsa. Second, Francisco already expressed his misgivings about the diesel fuel, fearing that they might be stolen property,29 yet he did not verify with CBCI the authority of Bacsa to sell the diesel fuel. Third, Francisco relied on the receipts issued by Bacsa which were typewritten on a half sheet of plain bond paper.30 If Francisco exercised reasonable diligence, he should have asked for an official receipt issued by CBCI. Fourth, the delivery to Francisco, as indicated in Petron’s invoice, does not show that CBCI authorized Bacsa to sell the diesel fuel to Francisco. Clearly, Francisco failed to exercise the standard of conduct expected of a reasonable person who is blind.
