Decision: Woodby v. INS, 385 U.S. 276 (1966).

The government needed more than evidence that could survive appellate review. In Woodby v. Immigration and Naturalization Service, decided with Sherman v. INS on December 12, 1966, the Supreme Court required clear, unequivocal, and convincing evidence of the facts supporting deportation. The critical distinction was how certain the agency had to be before ordering deportation, not merely whether a reviewing court could find substantial evidence in the record. The Court set aside both appellate judgments and required further administrative proceedings under the correct burden. Woodby, 385 U.S. 276, 277, 282–286 (1966).

Two records left the agency’s degree of certainty unclear

In Sherman’s case, the government alleged that a longtime resident had traveled abroad under a passport issued in another name and returned without inspection as a noncitizen. Identity was the decisive factual link. A witness initially could not identify Sherman or remember the passport name. He eventually connected Sherman to the journey but acknowledged that his recollection of events 27 years earlier was imperfect and that his identification might be mistaken. 277–279.

The agency nevertheless ordered deportation. Its decisions used several formulations about the strength of the evidence without explaining the burden governing the disputed travel and identity findings. The Second Circuit first required proof beyond a reasonable doubt, then changed course on rehearing and accepted reasonable, substantial, and probative evidence. That disagreement exposed the difference between identifying persuasive evidence and specifying the required degree of persuasion. 279–280.

Woodby’s case presented a different factual dispute under a post-entry conduct charge. She asserted duress for an earlier period; the agency did not decide that defense’s validity because it found that the conduct continued after the alleged duress ended. Neither the hearing officer nor the Board explained how certain the government’s proof had to make them. The Sixth Circuit upheld the order by asking whether substantial evidence supported it. The Supreme Court therefore faced two records in which the reviewing court’s evidentiary standard had not answered the agency-level burden question. 280–281.

Substantial-evidence review was not the agency’s burden of persuasion

The government relied on two provisions of the statute then in force. Section 106(a)(4) made an order conclusive if supported by reasonable, substantial, and probative evidence on the whole record. Section 242(b)(4) required that quality of evidence for a valid deportability decision. The Second Circuit treated the language as Congress’s choice of the government’s burden. 281.

The majority read the provisions differently. Section 106 governed judicial review by its wording, placement and history. Section 242 addressed the nature and quality of the evidence; it did not specify how firmly that evidence must establish the charged facts. An appellate court could ask whether a finding had substantial support only after the factfinder applied the right burden. The Court illustrated the distinction with criminal proceedings: A trial burden and an appellate sufficiency test perform different jobs. It did not adopt the criminal burden for deportation. 282–284.

This matters when a decision recites that the record supports a charge but never resolves a serious conflict under the governing persuasion standard. A later court’s ability to identify supporting evidence does not, by itself, establish that the agency used the correct burden when choosing between competing accounts.

Why the majority required stronger proof

Having found no congressional choice of a degree of proof, the majority treated that question as one courts traditionally resolve. Deportation was civil, but its consequences could be more severe than those in ordinary civil litigation. The Court drew on the heightened proof required in denaturalization and expatriation cases and rejected a bare preponderance as insufficient for facts establishing deportability. The resulting standard was clear, unequivocal, and convincing evidence—not proof beyond a reasonable doubt. 284–286.

Justice Clark, joined by Justice Harlan, dissented. They read the statutory language and history as Congress’s selection of the applicable administrative evidentiary standard and objected to the Court’s stronger requirement. Their disagreement concerned the legal source and degree of proof, not a competing Supreme Court finding that the disputed allegations in these two records had been established. 287–292.

The remand and the current removal statute answer different questions

The Supreme Court set aside the two court-of-appeals judgments and directed remand to the immigration agency for proceedings consistent with the proper burden. It did not itself decide whether the government could ultimately prove each charge under that burden. The record had to be evaluated using the right standard. 286.

A current case starts with the current statute, not an assumption that every immigration issue uses Woodby’s 1966 wording. 8 U.S.C. § 1229a(c)(3)(A) now places a clear-and-convincing burden on the government to establish deportability for a noncitizen who has been admitted. It separately requires reasonable, substantial, and probative evidence for a valid deportability decision. The statute thus expressly addresses the two concepts that Woodby distinguished.

Other parts of that same section allocate different burdens. Section 1229a(c)(2) governs a noncitizen’s proof of entitlement to admission or, where applicable, lawful presence pursuant to a prior admission. Section 1229a(c)(4) places eligibility and discretionary-relief burdens on the applicant for relief. Identifying the admission posture, the actual charge and the requested relief comes before deciding who must prove a disputed fact. Our analysis of Landon v. Plasencia addresses a related but different problem: A returning resident’s procedural protections and whether the particular hearing was fair.

What to examine in a disputed removal charge

• The charged facts: Match each required fact to the Notice to Appear, the government’s records and any admissions. A disagreement about identity or dates needs a focused evidentiary response.
• The agency’s reasoning: Identify which conflicting account the decision accepted and what burden it applied. A statement that evidence exists is not the same as an explanation that it meets the required degree of proof.
• The procedural posture: Separate an admitted person’s deportability charge from admission and relief questions before assigning a burden.
• The review record: Preserve the exhibits, hearing testimony and agency decisions needed to show both the disputed inference and the legal standard used. Woodby’s remand illustrates why that distinction can affect the next proceeding without guaranteeing its outcome.
