Final answer:
The court found Liberati liable in Antonis v. Liberati because he did not perform his job properly, which led to fraud, and because it was easy for him to verify the work correctly but he failed to do so.
Step-by-step explanation:
In the case of Antonis v. Liberati, the court held that Liberati was liable because a) he had not performed his job adequately, which led to the occurrence of the fraud, and b) it would have been easy for him to ensure that the work had been done correctly. Both these factors contributed to the determination of his liability. This implies a standard of care was expected from Liberati, which he failed to meet, allowing the fraud to happen when it could have otherwise been prevented given his job responsibilities and the relative ease with which he could have verified the work.
In Antonis v. Liberati, the court held that Liberati was liable because of a) If he had done his job, the fraud would not have occurred and b) It was an easy matter for him to make sure the work had been done correctly. The court found that Liberati, being trained to do that particular type of job, had a duty to ensure that the work was done correctly. Therefore, the correct answer is d) A and B.
