The case of United States, Trustee v. Oregon in 1960 revolved around the issue of whether a state could tax the income generated by federal property leased to private entities. The U.S., as trustee for an Indian tribe, owned land that was leased to private businesses and individuals who used it for various commercial purposes. The State of Oregon imposed a tax on these lessees based on their income from this federally-owned land. However, the Supreme Court ruled against Oregon's right to impose such taxes. The court held that while states have broad taxing powers under the Constitution, they cannot interfere with or burden federal activities without consent from Congress - which is known as intergovernmental immunity doctrine. In this case, since there was no congressional authorization allowing states to levy taxes on income derived from federal lands leased out by tribes or other entities acting under authority granted by Federal law (such as U.S., acting as trustee), those taxes were deemed unconstitutional interference with Federal functions and thus invalid.

The dissenting opinion in the case of UNITED STATES, TRUSTEE, v. OREGON argued that the majority's decision to allow Oregon to claim a portion of federal bankruptcy estate funds was inconsistent with previous rulings and interpretations of federal law. The dissent contended that under Section 3466 of the Revised Statutes, claims by states should be subordinate to those made by private creditors in cases where an insolvent debtor owes debts both federally and at state level. They believed this interpretation would ensure fairness among all creditors and prevent any preferential treatment based on jurisdictional status. Furthermore, they expressed concern over potential complications arising from different states having varying laws regarding debt collection from bankrupt estates; thus arguing for uniformity through adherence to federal law.
