In the 1891 case of Northern Pacific Railroad Company v. Amato, the U.S. Supreme Court ruled in favor of Northern Pacific Railroad Company (NPRC). The dispute arose when NPRC sold land to a buyer who later defaulted on payment, leading NPRC to reclaim and resell it. However, during this period, Antonio Amato had leased part of this land from the initial buyer for farming purposes and made significant improvements upon it. When NPRC reclaimed ownership, they did not recognize Amato's lease or his claim over these improvements. Amato sued for compensation but was unsuccessful at both district court level and on appeal at supreme court level because he failed to prove that he was an innocent purchaser without notice about potential issues with title ownership when leasing from the original defaulter. The Supreme Court held that as per law established by previous cases like Ruckman v Russell (1869), any individual dealing with property under questionable circumstances should be aware that their rights may be compromised if legal complications arise regarding rightful ownership.

The dissenting opinion in the case of Northern Pacific Railroad Company v. Amato argued that the majority's decision was inconsistent with previous rulings and failed to properly interpret relevant legislation. The dissenting justices believed that the railroad company had a clear right, under federal law, to sell its land without restrictions or conditions imposed by state laws. They asserted that Congress intended for these lands to be sold freely in order to fund railway construction and promote settlement in western territories. Therefore, they contended that any attempt by states to regulate these sales infringed upon this federal prerogative and should not be upheld by the court. Furthermore, they disagreed with the majority's interpretation of "bona fide purchasers," arguing it contradicted established legal definitions and principles regarding property rights.
