What type of laws does the Supreme Court review?

The Supreme Court primarily reviews decisions made by lower courts, which often involve interpreting federal and state laws. This function is essential because the Court's role is to ensure that the law is applied consistently across the country, and when lower courts reach different conclusions on the same issue, it can necessitate Supreme Court review to resolve these discrepancies.

When lower courts issue rulings on cases, particularly those involving constitutional issues or federal law, parties dissatisfied with the outcome can appeal to the Supreme Court. The Court selectively hears cases that have significant legal implications, usually those that could clarify or set precedent in law. This process helps uphold the rule of law and ensures that justice is uniformly administered in the United States.

The other options, while related to law, do not precisely capture the Supreme Court's core function of reviewing lower court decisions for overall legal interpretation and consistency.
