In the case of Florida et al. v. United States et al., 1930, the Supreme Court was asked to resolve a dispute between states over apportionment of water from a river that flowed through their territories. The State of Florida and Alabama sued Georgia for equitable apportionment of waters from the Apalachicola-Chattahoochee-Flint River Basin (ACF Basin). They claimed that Georgia's consumption significantly reduced downstream flows causing harm to oyster fisheries in Apalachicola Bay and also impacting power generation capabilities at Farley Nuclear Plant in Alabama. The court ruled against Florida stating it failed to prove by clear and convincing evidence that imposing a cap on Georgia’s water use would provide an effective remedy for its alleged harms without harming other stakeholders like Atlanta city residents or farmers who rely on this basin for drinking water supply and irrigation respectively. This decision underscored how interstate disputes over shared natural resources can be complex, requiring careful balancing of interests among multiple parties.

In the dissenting opinion for Florida et al. v. United States et al., Justice Stone argued that the majority's decision to uphold a federal law prohibiting shipment of filled milk (milk mixed with non-milk fats) was an overreach of Congress' power under the Commerce Clause. He contended that while it is within Congress' purview to regulate interstate commerce, this should not extend to regulating what products can be sold simply because they might cross state lines in trade. Furthermore, he disagreed with the majority's view that filled milk was inherently harmful and deceptive; rather, he believed such determinations should be left up to individual states or consumers themselves based on their own judgment and preferences. In his view, if every product deemed by some as unhealthy or undesirable were banned from interstate commerce, it would lead to an untenable expansion of federal regulatory power at the expense of state sovereignty and individual freedom.
