In the case of Otte, Trustee in Bankruptcy v. United States et al., 1974, the Supreme Court was asked to determine whether federal tax liens or bankruptcy trustee's rights took precedence when a taxpayer declared bankruptcy after a notice of federal tax lien had been filed but before any property had been seized by the IRS. The court ruled that under Section 70c of the Bankruptcy Act, a trustee in bankruptcy is given no greater rights than an unsecured creditor with respect to certain types of property and therefore cannot prevail over previously attached federal tax liens. This decision clarified that even if no levy has been made at all prior to commencement of proceedings under Chapter XI (arrangement proceeding), once there is assessment followed by demand for payment and refusal thereof - which are prerequisites for creation of valid lien - then such lien attaches not only on date it arises but also relates back and fastens onto status quo as it existed at time these events occurred.

In the dissenting opinion for Otte, Trustee in Bankruptcy v. United States et al., Justice Douglas argued that the majority's decision violated the spirit of bankruptcy law by allowing tax claims to supersede other creditors' rights. He contended that this interpretation undermined Congress's intent when it enacted bankruptcy legislation, which was designed to distribute a debtor's assets fairly among all creditors rather than favoring government entities over private ones. Furthermore, he disagreed with the majority’s view on “secured” and “unsecured” status of taxes owed under Section 67(b) of Bankruptcy Act; instead asserting that they should be treated as unsecured debts subject to discharge in bankruptcy proceedings. In his view, treating tax claims differently from other types of debt unfairly disadvantaged private creditors and contradicted fundamental principles underlying U.S.'s bankruptcy system.
