In the case of California National Bank v. Thomas in 1898, the U.S Supreme Court ruled on a dispute involving debt repayment and bankruptcy laws. The defendant, Mr. Thomas, had taken out loans from the California National Bank but later filed for bankruptcy before he could repay them fully. The bank claimed that since they were unaware of his insolvency at the time of lending him money, they should be exempted from standard bankruptcy procedures which would discharge Mr. Thomas's debts to them. The court disagreed with this argument and upheld lower courts' decisions favoring Mr.Thomas's right to have his debts discharged under existing bankruptcy law despite any ignorance by creditors about his financial state when extending credit or loaning funds to him. This ruling reinforced that all creditors are subject to equal treatment under federal bankruptcy laws regardless of their knowledge or lack thereof concerning a debtor’s solvency status at the time credit was extended.

In the dissenting opinion for California National Bank v. Thomas, Justice Brewer argued that the majority's decision failed to properly interpret and apply relevant banking law. He contended that a bank should not be held liable for accepting deposits from an insolvent corporation if it was unaware of the insolvency at the time of transaction. According to him, banks are not expected or required by law to investigate every depositor's financial status before accepting their money; such a requirement would place an unreasonable burden on them and disrupt normal business operations. Furthermore, he stated that there is no legal precedent supporting this kind of liability for banks in similar situations where they acted without knowledge or intent of wrongdoing. Therefore, he disagreed with holding California National Bank responsible under these circumstances.
