The Supremacy Clause is a part of the United States Constitution, specifically found in Article VI, Clause 2. It establishes that the Constitution, along with federal laws and treaties, takes precedence over state laws. This means that if there is a conflict between state and federal law, federal law will prevail. This clause ensures a unified legal framework across the country, promoting consistency and stability. It also reinforces the authority of the federal government, allowing it to operate effectively while limiting the power of individual states. The Supremacy Clause is essential for maintaining the balance of power in the U.S. legal system.
