In the 1912 case of Keatley v. Furey, the U.S Supreme Court was tasked with resolving a dispute over property rights and mortgage payments. The American Guaranty Company had gone into receivership, and its receiver, Keatley, sought to collect on a mortgage that the company held against property owned by Furey. However, Furey argued that he had already paid off his debt to another party who claimed to be an agent of American Guaranty Company before it went into receivership. The court ruled in favor of Keatley stating that there was no evidence proving this other party's authority as an agent for collecting debts owed to the company prior to its insolvency proceedings. Therefore, since these payments were not made directly or indirectly through authorized channels towards reducing his debt obligation under lawfully executed agreements or contracts with American Guaranty Company itself; they could not be recognized as valid discharges from liability for repayment due on said outstanding loan balance still legally enforceable by rightful claimants like Mr.Keatley acting in capacity as appointed receiver during ongoing bankruptcy process.

In the dissenting opinion for Keatley v. Furey, it was argued that the majority's decision to uphold a lower court ruling in favor of Furey was incorrect. The dissenters believed that American Guaranty Company should have been allowed to recover funds from Furey because he had received them as part of an illegal transaction involving stock manipulation and fraud. They contended that allowing him to keep these ill-gotten gains would be tantamount to endorsing his fraudulent behavior and undermining public faith in financial institutions. Furthermore, they disagreed with the majority's interpretation of relevant laws and precedents, arguing instead for a stricter application which would prioritize protecting innocent parties who were harmed by such deceptive practices over preserving unlawful profits obtained through them.
