In the case of Security Mortgage Company v. Powers, Trustee in Bankruptcy (1928), the United States Supreme Court was tasked with determining whether a mortgage company could claim priority over other creditors in bankruptcy proceedings. The Security Mortgage Company had lent money to a debtor who subsequently filed for bankruptcy. The company argued that because it held a mortgage on some of the debtor's property, it should be paid before other unsecured creditors. However, under federal law at that time, secured and unsecured creditors were treated equally during bankruptcy proceedings unless state law provided otherwise. The court ruled against Security Mortgage Company stating that their lien did not give them any special rights or privileges over other general creditors in terms of payment order from the bankrupt estate’s assets. This decision upheld principles of equity distribution among all types of debtors without giving undue preference to one type over another based solely on security interests attached to loans made prior to filing for bankruptcy protection.

The dissenting opinion in the case of Security Mortgage Company v. Powers, Trustee in Bankruptcy argued that the majority's decision was inconsistent with previous rulings and failed to adequately consider relevant state laws. The dissent emphasized that under New York law, a mortgage is considered as an interest in land and not merely a lien or security for debt. Therefore, it should be treated as such when determining whether it can be transferred without formalities required by statute. They also pointed out that prior cases had established precedent recognizing this principle and allowing mortgages to pass through bankruptcy proceedings intact if they were validly created under state law before bankruptcy was declared. By failing to follow these precedents, the majority effectively allowed federal bankruptcy law to override state property rights without clear justification.
