How does supremacy clause impact dispute among states or between states and the national government?

The Supremacy Clause, found in Article VI of the U.S. Constitution, establishes that federal law takes precedence over state laws when there is a conflict between the two. This means that if a state law contradicts a federal law, the federal law will prevail, helping to maintain a uniform legal framework across the country. As a result, the Supremacy Clause plays a crucial role in resolving disputes between states or between states and the national government by ensuring that federal authority is upheld in matters of conflicting legislation. This provision helps to prevent a patchwork of state laws that could undermine national policies and regulations.
