Final answer:
The courts resolve conflicts between laws by upholding the supremacy of federal law over state law.
Step-by-step explanation:
When two laws come into conflict with each other, the courts play a crucial role in resolving the issue. In the United States, the Constitution establishes the supremacy of federal law over state law through the Supremacy Clause. This means that if there is a conflict between federal and state laws, the federal law prevails.
For example, if a state law legalizes marijuana, but federal law criminalizes it, the courts would likely uphold the federal law and consider the state law invalid.
The Supreme Court, as the interpreter and enforcer of the Constitution, has the final say in resolving conflicts between laws and ensuring that the Constitution is upheld.
