In Commercial National Bank of Cleveland v. Iola, the United States Supreme Court was asked to decide whether a bank could be held liable for the wrongful acts of its employees. The case involved a bank employee who had fraudulently issued a check to a third party without the bank's knowledge or consent. The bank argued that it should not be held liable for the employee's actions because it had no knowledge of the fraud and had taken reasonable steps to prevent it. The Supreme Court held that the bank could be held liable for the employee's actions. The Court reasoned that the bank had a duty to exercise reasonable care in the selection and supervision of its employees, and that it had failed to do so in this case. The Court also noted that the bank had failed to take reasonable steps to prevent the fraud, such as requiring the employee to obtain the bank's approval before issuing checks. The Court's decision established that banks can be held liable for the wrongful acts of their employees, even if the bank had no knowledge of the fraud and had taken reasonable steps to prevent it. This decision has been cited in numerous cases since then, and has become an important precedent in the area of banking law.

In Commercial National Bank of Cleveland v. Iola, the Supreme Court was asked to decide whether a bank could be held liable for failing to pay out money from an account that had been frozen due to a dispute between two parties. The majority opinion found in favor of the bank, holding that it did not have any legal obligation to pay out funds until the dispute was resolved. However, Justice Harlan dissented from this decision and argued that banks should be held responsible for their actions when they fail to honor customers’ requests for payment. He reasoned that if banks are allowed to freeze accounts without consequence then customers will lose faith in them as reliable financial institutions and may choose other options instead. Furthermore, he noted that allowing such behavior would create an imbalance of power between banks and their customers since banks can unilaterally refuse payment while customers cannot do so with impunity. In conclusion, Justice Harlan believed that imposing liability on banks who wrongfully deny payments is necessary in order ensure fairness and protect customer rights within banking relationships
