The delegation of rulings on disputes over tariff classification may not extend beyond how many years from effectivity?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (B)

Delegation of rulings on tariff classification is allowed only for a limited period, specifically up to three years from the law’s effectivity. This sunset clause ensures the authority remains temporary and that the arrangement can be revisited or reauthorized later, keeping the Tariff Commission’s oversight intact and preventing an indefinite handover of quasi‑judicial power.

Why this fits best: three years is the maximum allowed by the statute, giving enough time to implement and resolve disputes while preserving accountability and the option for renewal. A shorter period (two years) might be insufficient for stable administration, while longer periods (four or five years) would exceed the permitted limit and would require new enabling legislation or action to extend.
