Article 25 is not subject to the saving clause of subparagraph 4(a) of Article 1 (General

Scope) by virtue of the exceptions in paragraph 5 of that Article. Thus, rules, definitions, procedures, etc. that are agreed upon by the competent authorities under this Article may be applied by the United States with respect to its citizens and residents even if they differ from the comparable Code provisions. Similarly, as indicated above, U.S. law may be overridden to provide refunds of tax to a U.S. citizen or resident under this Article.

A person may seek relief under Article 25 regardless of whether he is generally entitled to benefits under Article 22 (Limitation on Benefits). As in all other cases, the competent authority is vested with the discretion to decide whether the claim for relief is justified.
