How do the national government and state governments resolve conflicts of law?

National and state governments resolve conflicts of law primarily through the Supremacy Clause of the U.S. Constitution, which establishes that federal law takes precedence over state law when there is a conflict. Additionally, the judiciary plays a crucial role in interpreting laws and adjudicating disputes, often through cases that reach the Supreme Court. States may also work collaboratively or through compacts to harmonize laws on shared issues. Ultimately, legal frameworks and procedures are in place to address and mitigate these conflicts effectively.
