Decision: Kwock Jan Fat v. White, 253 U.S. 454 (1920).

Kwock Jan Fat v. White involved a man claiming U.S. birth who was excluded after immigration officials discounted his proof and failed to preserve important favorable evidence in the record sent for review.

The citizenship claim turned on identity and credibility

The applicant presented family and community evidence connecting him to a person born in the United States.

Material favorable testimony disappeared from the record

Statements taken by officials that supported the claim were not included in the evidentiary record underlying the final administrative action. The practical record-review question is concrete: Does the file contain the witnesses’ actual identification evidence, or only the agency’s later summary of it? That comparison can expose an omission without assuming that the 1920 review procedure controls a modern filing.

Administrative finality depended on a fair hearing

Although courts ordinarily respected immigration factfinding, conclusiveness did not attach when essential evidence was withheld and the process departed from statutory fairness.

Habeas supplied relief from unlawful detention

The Supreme Court reversed on June 7, 1920, and remanded to the District Court for a trial on the merits, directing that the writ of habeas corpus issue. It did not simply order release unless the agency held another hearing. Kwock Jan Fat, 253 U.S. at 464–465.

Key takeaways

• Obtain the complete agency record and compare every version.
• Identify omitted evidence and explain why it is material.
• Preserve citizenship and identity proof from independent sources.
• Frame habeas relief around the defective process and lawful next proceeding.
