Under the U.S. Constitution's Supremacy Clause, federal laws and the Constitution are supreme, meaning they generally override conflicting state laws, not the other way around; however, states can enact laws providing greater protections or rights than federal minimums (e.g., higher minimum wage, stricter environmental rules), which prevail within that state, but states cannot nullify valid federal law or set lower standards where federal law requires uniformity. Federal law preempts state law when Congress intends a uniform national standard or when state laws interfere with federal objectives, like in immigration, bankruptcy, or interstate commerce.
