Starr International Company v. United States, 910 F.3d 527

Background

Starr International, a Swiss-domiciled parent company with significant U.S.-source dividend income, sought reduced U.S. withholding tax under the U.S.-Swiss income tax treaty (Article 22).
Starr did not meet Article 22’s automatic "limitation on benefits" tests and applied for discretionary relief under Article 22(6), which allows benefits "if the competent authority . . . so determines after consultation" and directs consideration of whether obtaining treaty benefits was a "principal purpose" of establishing residency.
The U.S. Competent Authority (IRS LB&I Deputy Commissioner) denied Starr’s request for relief, concluding that obtaining treaty benefits was at least one principal purpose of Starr’s move to Switzerland.
Starr filed for a tax refund (approx. $38 million) under 26 U.S.C. § 7422(a); the District Court dismissed the refund claim as a nonjusticiable political question and allowed an APA claim instead, later granting summary judgment for the government on the APA claim.
The D.C. Circuit reversed the dismissal on political-question grounds, held that Starr has an adequate remedy under § 7422(a) (so no APA cause of action), vacated the APA-summary judgment, and remanded for the refund claim to proceed.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Starr's § 7422 tax-refund claim is barred by the political-question doctrine	Court can adjudicate whether IRS misapplied Article 22(6); this is a legal treaty-interpretation question	Judicial decision would intrude on Executive foreign-relations/consultation prerogatives and foreseeably preordain consultation outcome	Reversed dismissal: political-question doctrine does not bar adjudication; court may decide and, if needed, stay for or afford consultation effects later
Whether Starr has a cause of action under the APA	APA permits review of IRS denial as arbitrary and capricious	§ 7422(a) provides an adequate judicial remedy for tax refund disputes, precluding APA jurisdiction under 5 U.S.C. § 704	Starr lacks an APA cause of action because § 7422(a) is the appropriate and adequate remedy; APA claim must be dismissed
Proper procedural vehicle for resolving entitlement to treaty benefits	Use § 7422 refund suit to contest validity of the tax collection and IRS denial	Government preferred APA for review of agency action	§ 7422(a) is the correct vehicle for challenges to individual tax assessments seeking monetary relief; refund suit should proceed
Standard and scope of judicial review of IRS application of Article 22(6) (principal-purpose test)	Court can apply ordinary treaty-interpretation tools and the Technical Explanation’s principal-purpose standard to review the IRS determination	Executive-branch treaty interpretations and consultation have weight and foreign views may inform, but are not dispositive	Court to apply traditional treaty-interpretation rules to review IRS application; agency interpretations are entitled to deference but the District Court must evaluate the record in the refund action
