The U.S. Supreme Court case Crancer et al., Doing Business as Valley Steel Products Co. et al., v. Lowden et al., Trustee, 1941, revolved around a dispute over the bankruptcy of a steel company and its subsequent reorganization plan under Section 77B of the Bankruptcy Act. The petitioners were creditors who objected to the plan because it did not provide them with adequate protection for their claims against the bankrupt company's assets. They argued that they should have been given priority in payment over other unsecured creditors due to their status as secured creditors with liens on specific property owned by the debtor company. However, both lower courts approved the reorganization plan despite these objections from secured creditors, leading to an appeal at Supreme Court level where it was held that while Section 77B does allow for some flexibility in dealing with creditor claims during corporate reorganizations; this flexibility is not unlimited and must still respect fundamental principles of equity including respecting lien priorities among different classes of creditors. Therefore, since there was no evidence showing any exceptional circumstances justifying deviation from normal rules regarding lien priorities or any unfair prejudice towards petitioners' interests; nor sufficient justification provided by respondents for treating all general unsecured claims equally without regard to existing liens - The Supreme Court reversed previous rulings approving such treatment and remanded case back down for further proceedings consistent with its opinion.

In the dissenting opinion for Crancer et al., Doing Business as Valley Steel Products Co. et al., v. Lowden et al., Trustee, 1941, it was argued that the majority's decision to uphold a lower court ruling allowing trustees of bankrupt companies to recover payments made by those companies prior to bankruptcy was incorrect and harmful. The dissenters believed this interpretation of Section 60b of the Bankruptcy Act unfairly penalized creditors who had received payment in good faith and without any knowledge or suspicion that their debtor would soon declare bankruptcy. They contended that such an interpretation could discourage trade credit and harm commerce overall by creating uncertainty among businesses about whether they can rely on payments received from customers who later go bankrupt. Furthermore, they disagreed with the majority's view that Congress intended such a broad application of Section 60b when it passed the law.
