Padilla Advice Standard in the Fourth Circuit: Telling a Client He Is “Deportable/Removable” Suffices Without Predicting “Mandatory Deportation”

I. Introduction

United States v. Sergio Carrillo Murillo (Fourth Circuit, Mar. 5, 2026) is the second published appellate decision arising from Sergio Carrillo’s 28 U.S.C. § 2255 motion attacking his 2016 guilty plea to a 21 U.S.C. § 846 cocaine-distribution conspiracy. Carrillo, a lawful permanent resident and noncitizen, alleged ineffective assistance of counsel under the Sixth Amendment because his retained lawyer, Katherine Martell, did not advise him that his plea would trigger immigration consequences culminating in deportation.

The first appeal, United States v. Carrillo Murillo, 927 F.3d 808 (4th Cir. 2019) (“Carrillo Murillo I”), held Carrillo established Strickland prejudice and remanded for the district court to decide Strickland deficient performance after an evidentiary hearing. On remand, the district court held Martell’s immigration advice was constitutionally adequate. The Fourth Circuit affirmed, over a dissent.

Core issue: Under Padilla v. Kentucky and Fourth Circuit precedent (notably United States v. Swaby), is counsel constitutionally required to characterize removal as “mandatory”/“presumptively mandatory,” or to advise ineligibility for particular immigration relief, when counsel has correctly advised the client he will be “deportable,” “removable,” and placed in removal proceedings?

II. Summary of the Opinion

The Fourth Circuit affirmed the denial of § 2255 relief because Carrillo failed to prove Strickland v. Washington deficient performance. The court accepted the district court’s factual finding that Martell told Carrillo he would be “deportable” and “removable” and would face deportation proceedings, but she did not tell him deportation was “mandatory” or “presumptively mandatory,” nor that he was ineligible for cancellation of removal.

The majority held that, even where the conviction is an “aggravated felony” making a noncitizen deportable, it is not constitutionally required that counsel use the labels “mandatory deportation” or “presumptively mandatory deportation,” nor advise that deportation (or a deportability finding) is certain—because immigration outcomes can remain uncertain due to potential forms of “other relief” and executive discretion in effectuating removal.

Judge Thacker dissented, arguing the majority’s approach conflicts with Padilla v. Kentucky and United States v. Swaby, asserting that aggravated-felony consequences are sufficiently “clear” that counsel must communicate the essentially mandatory nature of removal, not merely a possibility.

III. Analysis

A. Precedents Cited

1. The Strickland framework and plea-prejudice standards

  • Strickland v. Washington, 466 U.S. 668 (1984): The opinion reiterates the two independent prongs—deficient performance and prejudice—and stresses that a court may resolve an ineffective-assistance claim on either prong without deciding the other. This becomes decisive when the panel rejects Carrillo’s attempt to treat the earlier prejudice finding as implying deficiency.
  • Hill v. Lockhart, 474 U.S. 52 (1985): Provides the plea-prejudice standard (“reasonable probability” the defendant would have gone to trial absent counsel error), which framed the first appeal.
  • Spencer v. Murray, 18 F.3d 229 (4th Cir. 1994): Cited for the proposition that deficiency and prejudice are “separate and distinct” elements—supporting the majority’s rejection of Carrillo’s “prejudice implies deficiency” theory.
  • United States v. Rangel, 781 F.3d 736 (4th Cir. 2015) and Moore v. Hardee, 723 F.3d 488 (4th Cir. 2013): Illustrate the permissible sequencing of Strickland analysis (courts may assume deficiency and decide prejudice first, or vice versa).
  • United States v. Scripps, 961 F.3d 626 (3d Cir. 2020): Used by analogy to show prejudice can exist even if deficient performance has not yet been established, reinforcing that the prongs are not logically fused.

2. Padilla and the immigration-advice line

  • Padilla v. Kentucky, 559 U.S. 356 (2010): The opinion treats Padilla as setting the constitutional baseline: counsel must inform the client whether a plea carries a risk of deportation; when consequences are “truly clear,” counsel must provide “correct advice.” The majority reads Padilla as requiring correct advice about deportability risk, not guarantees about actual removal, and not necessarily a particular set of “mandatory” labels.
  • United States v. Swaby, 855 F.3d 233 (4th Cir. 2017): Central Fourth Circuit comparator. The majority distinguishes Swaby as involving “patently incorrect advice” (a mistaken statutory interpretation leading counsel to advise only a risk rather than certainty). The dissent reads Swaby as compelling “mandatory” characterization for aggravated felonies.
  • United States v. Akinsade, 686 F.3d 248 (4th Cir. 2012): Another misadvice case. The majority emphasizes Akinsade involved affirmative incorrect assurances, whereas Carrillo’s counsel allegedly gave correct “deportable/removable” advice; thus Akinsade does not answer the “how much more detail” question.
  • Lee v. United States, 582 U.S. 357 (2017): Cited for the real-world gravity of deportation consequences and the “mandatory” nature of deportation for certain aggravated felonies—yet the majority separates that description from a constitutional requirement to predict inevitability.

3. Immigration-law context and persuasive authority

  • Dilang Dat v. United States, 983 F.3d 1045 (8th Cir. 2020): Persuasive authority supporting the majority’s caution against “absolutes” and reading Padilla as requiring advice that a conviction makes the defendant “deportable,” not that deportation is “mandatory or certain.”
  • United States v. Cazarez-Santos, 66 F. Supp. 3d 1301 (S.D. Cal. 2014): Persuasively cited for the concern that overly dire “virtual certainty” warnings could distort plea decision-making and deter defendants from pursuing immigration remedies.
  • Moncrieffe v. Holder, 569 U.S. 184 (2013): Appears in the dissent’s chain of authority (via Swaby) for the aggravated-felony/cancellation-of-removal consequences and the practical “mandatory” character of removal.

4. Standards of review and law-of-the-case themes

  • United States v. Stitt, 552 F.3d 345 (4th Cir. 2008) and United States v. Nicholson, 611 F.3d 191 (4th Cir. 2010): Provide the review framework after an evidentiary hearing (clear error for facts; de novo for legal conclusions; de novo for mixed questions such as deficient performance).
  • United States v. Luck, 611 F.3d 183 (4th Cir. 2010) and United States v. Poindexter, 492 F.3d 263 (4th Cir. 2007): Recounted from Carrillo Murillo I to explain the earlier de novo review posture when no evidentiary hearing occurred.
  • United States v. Banks, 29 F.4th 168 (4th Cir. 2022) and McMellon v. United States, 387 F.3d 329 (4th Cir. 2004): Invoked in the dissent to argue the majority’s approach conflicts with binding circuit precedent and cannot be reconciled with earlier controlling decisions.

B. Legal Reasoning

1. Prejudice does not “necessitate” deficiency

The majority’s first move is structural: it rejects Carrillo’s attempt to convert the earlier prejudice holding into an implied deficiency holding. Relying on Strickland v. Washington and Spencer v. Murray, the court emphasizes prong independence and the legitimacy of deciding ineffective-assistance claims on only one prong. Carrillo Murillo I expressly declined to decide deficiency and remanded for the district court to do so; therefore, no doctrinal shortcut applied on the second appeal.

2. Distinguishing “incorrect advice” cases from “degree-of-detail” cases

The majority reads Padilla v. Kentucky, United States v. Swaby, and United States v. Akinsade as anchored in counsel giving incorrect immigration advice (or false assurances) when the removal consequence was clear. Here, by contrast, the factual finding credited by the district court is that Martell correctly advised Carrillo he would be “deportable,” “removable,” and placed into removal proceedings. Thus, in the majority’s view, the case does not ask whether counsel must avoid misadvice; it asks whether the Constitution requires additional, more emphatic phrasing (“mandatory”/“presumptively mandatory”) and counseling about particular relief ineligibilities.

3. The opinion’s operative rule: correct “deportable/removable” advice satisfies Padilla in this setting

The court treats as “succinct and straightforward” the statutory point that an aggravated felony makes a noncitizen deportable under 8 U.S.C. § 1227(a)(2)(A)(iii). The constitutional duty, as the majority frames it, is to provide correct advice reflecting that consequence—i.e., that the plea “carr[ies] a risk of deportation by rendering him deportable.” On that framing, Martell met the constitutional minimum by saying “deportable,” “removable,” and “subject to deportation proceedings.”

4. Why “mandatory deportation” wording is not constitutionally required

The majority draws a line between (a) being legally deportable (a clear statutory consequence of the aggravated felony) and (b) being deported as an actual outcome, which can be affected by “other relief” and by executive discretion in enforcing removal. Because “mandatory deportation” and “presumptively mandatory deportation” can be misunderstood as inevitability, the majority—echoing Dilang Dat v. United States and United States v. Cazarez-Santos—endorses caution against “absolutes” and holds the Sixth Amendment does not require such labels.

5. No constitutional duty (on this record) to advise categorical “no relief” or ineligibility for cancellation

Carrillo argued Martell was required to tell him he was ineligible for cancellation of removal under 8 U.S.C. § 1229b(a)(3) and therefore would be found deportable with certainty. The majority rejects this as underdeveloped: Carrillo acknowledged possible “other relief,” yet did not demonstrate he was clearly ineligible for all relief routes. Without establishing that total ineligibility was itself “clear” and “straightforward,” the court refused to constitutionalize a duty to advise “zero relief” as a certainty.

C. Impact

1. A clarifying (and narrowing) gloss on Padilla within the Fourth Circuit

The decision is best read as a doctrinal clarification for cases where counsel gives correct advice that a plea makes the client “deportable/removable,” but does not use “mandatory” terminology. It signals that, absent affirmative misadvice, the Fourth Circuit will not readily find deficient performance merely because counsel did not emphasize the near-inevitability of removal for aggravated felonies in the strongest possible terms.

2. Practical effects on § 2255 litigation

Postconviction challenges may increasingly turn on evidentiary proof of what was actually said. If the government can establish counsel used “deportable/removable” language and warned of removal proceedings, this opinion supplies a strong basis to defeat deficiency—even if counsel also described deportation as a “possibility” and even if removal was, as a practical matter, highly likely.

3. Potential tension with existing circuit precedent (highlighted by the dissent)

Judge Thacker’s dissent frames the decision as inconsistent with United States v. Swaby and the aggravated-felony line that treats deportation as “akin to mandatory.” That dissent may invite future panels (or en banc review) to revisit how much “certainty” counsel must communicate when aggravated-felony consequences are at issue, especially where counsel’s phrasing sounds probabilistic (“may”) rather than categorical (“will be deportable”).

IV. Complex Concepts Simplified

  • “Aggravated felony” (immigration): A term of art under 8 U.S.C. § 1101(a)(43). Many drug trafficking offenses qualify. The label triggers severe immigration consequences.
  • “Deportable” vs. “deported”: “Deportable” generally means the statute authorizes removal based on the conviction (a legal status/ground). “Deported” is the real-world outcome after proceedings and enforcement decisions. The majority’s rule turns on this distinction.
  • “Cancellation of removal”: A discretionary form of relief that can allow some noncitizens to remain. Lawful permanent residents convicted of an aggravated felony are statutorily barred from this relief under 8 U.S.C. § 1229b(a)(3).
  • “Strickland deficient performance”: Whether counsel’s actions fell below “reasonable” professional norms. In this case, the key question was not whether counsel mentioned immigration consequences at all, but whether counsel had to describe them as “mandatory” or “certain.”
  • “Strickland prejudice” in plea cases: Whether there is a reasonable probability the defendant would have rejected the plea and gone to trial if properly advised (Hill v. Lockhart). Carrillo won this issue in Carrillo Murillo I, but lost the deficiency issue on remand and in this appeal.

V. Conclusion

United States v. Sergio Carrillo Murillo establishes a consequential Fourth Circuit clarification of Padilla v. Kentucky: where the aggravated-felony consequence is clear enough to require correct advice, counsel satisfies the Sixth Amendment by accurately advising that the plea renders the client “deportable/removable” and subject to removal proceedings; counsel is not constitutionally required, on this record, to label deportation “mandatory” or “presumptively mandatory,” nor to advise categorical certainty of deportation or a “zero relief” conclusion without a demonstrated, equally clear legal basis.

The dissent underscores that the scope of Padilla duties remains contested at the margin—particularly in aggravated-felony cases where deportation is practically near-inevitable—setting up a likely focal point for future litigation about how explicit counsel must be when “clear” immigration consequences are also, in practice, overwhelmingly likely to culminate in removal.
