Which court has exclusive jurisdiction over cases involving the validity or constitutionality of tax laws, rules, and regulations?

• A. Court of Appeals
• B. Court of Tax Appeals
• C. Regional Trial Court
• D. Supreme Court

Answer: (B)

The main idea is that challenges to the validity or constitutionality of tax laws, rules, and regulations are handled by a specialized court that has exclusive original jurisdiction over these issues. The Court of Tax Appeals is designed to hear disputes arising from taxation and, specifically, to decide whether a tax statute, rule, or regulation is valid or constitutional. This exclusivity means those questions are brought there first rather than to general trial courts, ensuring expertise and consistent application of tax law across the country. After the CTA rules, its decisions can be reviewed by higher courts in the normal appellate process. The other courts do not have the authority to hear these original challenges to tax laws, rules, and regulations.
