In the case of National Mutual Building and Loan Association v. Brahan, 1903, the United States Supreme Court ruled on a dispute involving property rights. The National Mutual Building and Loan Association had sold a piece of land to Mrs. Brahan but later claimed that she still owed them money for it due to an error in their bookkeeping system which led to her being undercharged initially. Mrs. Brahan argued that she had paid off her debt completely as per the original agreement with the association. The court sided with Mrs. Brahan, stating that once a contract has been fully executed by both parties involved (in this case, when ownership was transferred from the association to Mrs.Brahan), any mistakes discovered afterwards cannot be used as grounds for altering or voiding said contract unless fraud can be proven - something which wasn't applicable here since there was no evidence suggesting intentional deception on either side during negotiations over price terms. This decision reinforced legal principles related to contractual obligations and fairness in business transactions while also highlighting importance of accurate record-keeping practices within financial institutions.

In the dissenting opinion for National Mutual Building and Loan Association v. Brahan, Justice Harlan disagreed with the majority's interpretation of contract law principles. He argued that when a borrower enters into an agreement with a building and loan association, they are not simply borrowing money but becoming shareholders in the organization. Therefore, he believed that any profits made by such associations should be shared among all members including borrowers who have yet to fully repay their loans. This view contrasts sharply with the majority’s decision which held that only those who had repaid their loans were entitled to share in surplus earnings from investments or other sources of income beyond what was necessary to cover operating expenses and meet obligations towards creditors. According to Justice Harlan, this approach unfairly favored certain members over others despite everyone having contributed capital through payments on their loans or direct investment into shares.
