In the case of Thomson, Trustee of Chicago & Northwestern Railway Co., et al. v. Gaskill et al., 1941, the U.S Supreme Court ruled in favor of Gaskill and others who were creditors to a bankrupt railroad company. The court held that under Section 77B (now Chapter X) of the Bankruptcy Act, unsecured claims against a debtor's estate are not subordinated to secured claims unless there is an express statutory provision for such subordination or it arises from equitable considerations applicable on bankruptcy reorganization cases. In this case, no such provision was found nor did any equitable consideration arise warranting subordination; hence all claimants stood on equal footing irrespective of whether their claims were secured or unsecured.

In the dissenting opinion for Thomson, Trustee of Chicago & Northwestern Railway Co., et al. v. Gaskill et al., Justice Black disagreed with the majority's decision to uphold a lower court ruling that allowed creditors to recover their claims from a bankrupt railway company before bondholders could receive any payment. He argued that this was contrary to established bankruptcy law principles which prioritize secured creditors (like bondholders) over unsecured ones in insolvency proceedings. Furthermore, he contended that such an interpretation would discourage future investments in bonds and other forms of secured debt as it undermines their supposed security against losses during bankruptcy cases. The justice also criticized the majority for not adequately considering these potential economic implications on investment behavior and market stability.
