The United States Supreme Court case of the United States et al. v. Northern Pacific Railway Co. et al., 1932, revolved around a dispute over land grants given to the Northern Pacific Railway Company by Congress in 1864 for railway construction purposes across several states and territories. The government argued that certain lands were not included in this grant because they were part of an Indian reservation at the time or had been reserved for public uses prior to the passage of the act granting land to Northern Pacific Railroad Company (NPRC). NPRC disputed these claims, asserting its right over all granted lands regardless of their status at that time. The court ruled against NPRC on both counts, stating that Congress did not intend to include Indian reservations within railroad grants unless explicitly stated otherwise and also upheld earlier rulings which established that public use reservations made before a grant's passage are excluded from such grants unless specifically included therein. This decision clarified federal policy regarding railroad land grants and reaffirmed respect for Native American rights as well as protection for areas designated for public use.

In the dissenting opinion for United States v. Northern Pacific Railway Co., Justice Stone disagreed with the majority's decision to uphold a lower court ruling that allowed Northern Pacific Railway Company to retain lands granted by Congress in 1864, despite not having completed construction of their railway within a specified timeframe. He argued that this interpretation was inconsistent with Congressional intent and previous Supreme Court rulings on similar cases. According to Justice Stone, Congress intended for these land grants to incentivize railroad construction; if companies failed to meet their obligations within the stipulated time, they should forfeit any unearned lands back to public ownership. The majority’s decision effectively rewarded non-compliance and undermined public interest in favor of corporate interests.
