In the 1898 case of Guarantee Company v. Mechanics' Savings Bank and Trust Company, the U.S. Supreme Court dealt with a dispute over a mortgage foreclosure sale. The Guarantee Company had issued bonds for property that was later foreclosed upon by the Mechanics' Savings Bank and Trust Company due to unpaid debts. The bank then purchased this property at its own foreclosure sale, which led to litigation as it was argued that such an action violated Louisiana state law prohibiting creditors from buying their debtor's assets in order to satisfy their debt unless they do so through public auction or court judgment. The Supreme Court ruled in favor of the bank, stating that while Louisiana law did prohibit certain types of self-dealing transactions between creditors and debtors, it did not apply in this specific situation where a creditor bought back mortgaged property at its own foreclosure sale after default on payment by debtor. Therefore, there were no legal grounds for invalidating the transaction under existing laws.

In the dissenting opinion for Guarantee Company v. Mechanics' Savings Bank and Trust Company, it was argued that the majority's decision to uphold a lower court ruling in favor of Mechanics' Savings Bank and Trust Company was incorrect. The dissenting justices believed that the bank had not met its burden of proof to show that it should be entitled to recover from Guarantee Company on a surety bond. They contended that there were significant questions about whether or not the bank had acted prudently and within its rights under contract law when dealing with collateral tied to loans guaranteed by Guarantee Company. Furthermore, they disagreed with how certain evidence related to these issues was interpreted by both the trial court and their fellow Supreme Court justices in reaching their decisions.
