The Northern Pacific Railway Company v. The Department of Public Works of the State of Washington case in 1924 revolved around a dispute over whether or not the state could impose taxes on federal land granted to the railway company. The Supreme Court ruled that while states cannot tax lands owned by the United States, they can tax beneficial interests arising from those lands. In this case, it was determined that when Congress gave certain lands to Northern Pacific Railway Company for constructing railroads and telegraph lines, it transferred more than just bare legal title; it also conveyed beneficial interest which is taxable under state law. Therefore, even though these were technically federal lands given for public purposes (railroad construction), they carried with them benefits accruing to a private corporation which could be taxed by Washington State without infringing upon Federal sovereignty.

The dissenting opinion in the case of Northern Pacific Railway Company v. The Department of Public Works of Washington argued that the majority's decision was based on a misinterpretation and overextension of previous rulings regarding interstate commerce regulation. They contended that while states cannot directly regulate rates for interstate transportation, they can impose conditions upon corporations operating within their borders to ensure public safety and welfare. In this specific instance, it was argued that Washington State had not attempted to fix or control freight rates but merely required railway companies to maintain certain facilities for handling intrastate business as a condition for doing business within the state. Therefore, according to the dissenters, such requirements did not constitute an undue burden on interstate commerce and should have been upheld by court.
