Federalism and conflicts between state and federal regulation
🔹 1. McCulloch v. Maryland (1819)
Issue: Can a state tax a federal institution? Does Congress have the authority to create a national bank?
Facts: The State of Maryland imposed a tax on the Second Bank of the United States, which was a federally chartered institution. James McCulloch, the cashier of the Baltimore branch, refused to pay the tax, arguing it was unconstitutional.
Ruling:
The Supreme Court, under Chief Justice John Marshall, held that Congress had the implied power to create the bank under the Necessary and Proper Clause (Article I, Section 8).
The Court also ruled that Maryland could not tax the federal bank because "the power to tax involves the power to destroy," which would make the states supreme over the federal government — contrary to the Constitution.
Significance:
Established the supremacy of federal law over state law.
Reinforced broad federal powers through the Necessary and Proper Clause.
Key precedent for limiting state interference with federal operations.
🔹 2. Gibbons v. Ogden (1824)
Issue: Can a state grant exclusive navigation rights on waters that are part of interstate commerce?
Facts: New York granted a monopoly to Ogden for steamboat operation on its waters. Gibbons had a federal license to operate steamboats in interstate commerce, including those waters.
Ruling:
The Court ruled that the federal government has exclusive power to regulate interstate commerce, under the Commerce Clause (Article I, Section 8).
New York’s monopoly law conflicted with federal law and was therefore invalid.
Significance:
Reinforced the idea that federal law preempts state law when it comes to interstate commerce.
Broad interpretation of the Commerce Clause allowed the federal government to regulate more aspects of the economy.
🔹 3. Wickard v. Filburn (1942)
Issue: Can the federal government regulate wheat production intended for personal use under the Commerce Clause?
Facts: Roscoe Filburn, a farmer, grew more wheat than allowed under federal law but claimed it was for personal use and not for sale.
Ruling:
The Supreme Court held that even wheat grown for personal consumption could be regulated by Congress because, in the aggregate, such practices could affect interstate commerce.
Significance:
Greatly expanded the scope of federal power under the Commerce Clause.
Demonstrated that even local or non-commercial activities could be federally regulated if they had a substantial economic effect.
🔹 4. Arizona v. United States (2012)
Issue: Can states create their own immigration laws?
Facts: Arizona passed SB 1070, a strict immigration enforcement law. The federal government sued, arguing that immigration enforcement is a federal responsibility.
Ruling:
The Court struck down three of the four challenged provisions of the Arizona law as preempted by federal immigration law.
The only provision upheld was one allowing police to check immigration status during lawful stops.
Significance:
Confirmed that immigration is a primarily federal matter.
Reinforced the doctrine of preemption, where federal law supersedes conflicting state law.
Showed how states are limited in areas where Congress has clearly legislated.
🔹 5. Gonzales v. Raich (2005)
Issue: Can the federal government ban marijuana use allowed by state law?
Facts: California allowed medical marijuana use under state law. Raich and Monson used medical marijuana legally under state law but were targeted by federal DEA agents under the Controlled Substances Act (CSA).
Ruling:
The Court held that Congress could prohibit local cultivation and use of marijuana, even if it complied with state law, under the Commerce Clause.
Local use could affect supply and demand in the interstate market, justifying federal regulation.
Significance:
Affirmed federal supremacy in drug enforcement, even when state law permits otherwise.
Emphasized that state law does not immunize individuals from federal prosecution.
Deepened the conflict between states with legal cannabis and federal drug laws.
🔹 6. Murphy v. NCAA (2018)
Issue: Does a federal law prohibiting states from authorizing sports gambling violate the Tenth Amendment?
Facts: The Professional and Amateur Sports Protection Act (PASPA) barred states from authorizing sports gambling. New Jersey passed a law to allow it, challenging PASPA.
Ruling:
The Court held that PASPA violated the anti-commandeering doctrine, part of the Tenth Amendment.
The federal government cannot compel states to enact or enforce federal regulatory schemes.
Significance:
Strengthened states’ rights and limits on federal power.
Showed that while federal law is supreme, the federal government cannot force states to legislate in a particular way.
Important for understanding the boundaries of federalism in regulation.
