preemption doctrine
The preemption doctrine is a legal principle that occurs when a higher authority's law overrides or takes precedence over a lower authority's law. This often happens in the context of federal and state laws, where federal law can supersede state law if they conflict. For example, if Congress passes a law regulating interstate commerce, a state law that contradicts this federal law may be nullified. Preemption ensures a consistent legal framework, especially in matters where uniformity is necessary, such as environmental standards or consumer protection.

The preemption doctrine is a legal principle that occurs when a higher authority's laws or regulations take precedence over conflicting lower authority ones. In the United States, for example, federal laws can override state laws when both govern the same issue. This ensures uniformity and prevents states from enacting laws that would conflict with federal legislation. Preemption can be "express," where it's clearly stated, or "implied," where the federal intent to dominate a field is evident. Ultimately, it helps maintain a consistent legal framework across different jurisdictions.
