In the case of Clay Center v. Farmers' Loan & Trust Company (1891), the U.S Supreme Court ruled in favor of Farmers' Loan & Trust Company, upholding their right to collect on bonds issued by the city of Clay Center, Kansas. The city had argued that it was not liable for these debts because they were incurred as part of a fraudulent scheme perpetrated by railroad companies and other parties. However, the court found that since Farmers' Loan & Trust Company acted in good faith when purchasing these bonds and was unaware of any fraud at that time, they were entitled to payment from Clay Center regardless. This decision reinforced legal principles related to municipal debt obligations and upheld protections for innocent purchasers acting in good faith.

In the dissenting opinion for Clay Center v. Farmers' Loan & Trust Company, it was argued that the majority's decision to uphold a Kansas law limiting railroad rates was an overreach of state power and violated constitutional protections against arbitrary interference with private contracts and property rights. The dissent contended that while states have broad powers to regulate industries within their borders, these powers are not absolute and must be exercised in a reasonable manner. They believed that the rate set by Kansas lawmakers was so low as to effectively confiscate part of the railroads' property without just compensation, which is unconstitutional under the Fifth Amendment's Takings Clause. Furthermore, they disagreed with the majority's view that courts should defer to legislative judgments on economic matters; instead arguing for a more active judicial role in scrutinizing such decisions for potential constitutional violations.
