Scarborough Refined: Delaware Supreme Court Clarifies Strickland-Prejudice Analysis for Missed Plea-Withdrawal Motions

Introduction

In Smith v. State, No. 179, 2024 (Del. Aug. 14, 2025), the Supreme Court of Delaware revisited the interplay between ineffective assistance of counsel and a defendant’s post-conviction effort to withdraw a guilty plea. Robert L. Smith—who had pleaded Guilty But Mentally Ill (GBMI) to first-degree murder—claimed that his trial counsel performed deficiently by ignoring his written request to move for plea withdrawal. Although the Superior Court agreed that counsel’s performance was objectively unreasonable, it denied relief, finding no Strickland prejudice. On appeal, the High Court affirmed and, in doing so, delivered an important clarification of the Scarborough v. State factors used to gauge whether a trial court would have granted a motion to withdraw a plea.

Summary of the Judgment

1. Deficient Performance Conceded. Both the State and the courts accepted that trial counsel acted unreasonably when he failed either to file Smith’s requested motion or withdraw so Smith could proceed pro se.
2. Only Prejudice Contested. The dispositive question became whether, but for counsel’s error, there was a “reasonable probability” that (1) Smith would have insisted on going to trial and (2) the trial court would have granted the motion (Reed v. State).
3. Full Scarborough Analysis on Remand. After a remand, the Superior Court expressly addressed each of the five Scarborough factors, ultimately finding that factors (1) through (3) weighed against withdrawal and factors (4) and (5) were neutral or insufficient.
4. Supreme Court Affirmance. The Supreme Court held that the Superior Court did not abuse its discretion, emphasizing that: (a) a defendant must point to specific evidence of legal innocence; (b) Extreme Emotional Distress (EED) mitigation does not constitute “legal innocence,” especially where a defendant is a habitual offender; and (c) a theoretical absence of State prejudice does not outweigh an otherwise knowing and voluntary plea.

Analysis

Precedents Cited and Their Influence

• Strickland v. Washington, 466 U.S. 668 (1984) – Governs ineffective-assistance claims via the twin requirements of deficient performance and prejudice. The Delaware Supreme Court’s focus was entirely on the second prong.
• Scarborough v. State, 938 A.2d 644 (Del. 2007) – Provides the five-factor framework for deciding presentence motions to withdraw guilty pleas. The Court reiterated that the factors are questions to be answered, not a mechanical balancing test, and that any one factor may be dispositive.
• Reed v. State, 258 A.3d 807 (Del. 2021) – Required explicit consideration of Scarborough in post-conviction prejudice determinations; the Smith opinion enforces this mandate.
• Lafler v. Cooper, 566 U.S. 156 (2012) and Hill v. Lockhart, 474 U.S. 52 (1985) – Confirm that prejudice in the plea context turns on whether competent advice would have changed the outcome of the plea process.
• Various Delaware Superior Court cases (Capobianco, Wright, Harden) – Support the requirement that an assertion of legal innocence after a plea must be grounded in concrete evidence.

Legal Reasoning Explained

1. Framework Selection.
   Because only prejudice was disputed, the Court asked whether Smith could show that a motion to withdraw would likely have succeeded. Scarborough provides the template for that predictive inquiry.
2. Application of Scarborough Factors.
   The Superior Court’s factual determinations bound the Supreme Court absent abuse of discretion:
   • Procedural Defect (Factor 1) – Minor deviations from 11 Del. C. § 408 (GBMI procedure) and Taylor were deemed harmless because experts’ reports were reviewed.
   • Knowing & Voluntary Plea (Factor 2) – A thorough colloquy defeated any claim of involuntariness.
   • Legal Innocence (Factor 3) – • Self-defense: No specific supporting evidence. • EED: Merely a mitigation to manslaughter, not a ground for acquittal, and irrelevant here due to habitual-offender status.
     Absence of a viable innocence claim weighed heavily against withdrawal.
   • Adequate Counsel (Factor 4) – Favored Smith.
   • Prejudice to State / Court (Factor 5) – Neutral; no showing of prejudice, but this alone cannot compel withdrawal.
3. Cumulative Assessment.
   Because factors 1–3 undermined Smith’s position and factor 3 was considered paramount, the Court concluded that Smith failed to establish a “reasonable probability” that the trial court would have granted the motion. Therefore, no Strickland prejudice.
4. Clarifications Offered.
   The Court expressly held that:
   • EED, as a statutory mitigating circumstance, is not “legal innocence” for Scarborough purposes.
   • A defendant who merely voices a defense theory without evidentiary support cannot satisfy the legal-innocence factor.
   • Absence of prejudice to the State, standing alone, cannot override a knowingly entered plea.

Impact on Future Litigation

The decision tightens the standards for post-conviction plea withdrawal based on ineffective assistance:

• Higher Evidentiary Threshold for “Legal Innocence.” Counsel and defendants must marshal concrete facts—affidavits, forensic reports, witness statements—before the courts will credit an innocence assertion.
• Limited Use of Mitigation Doctrines. Arguments such as EED or voluntary intoxication, which lessen the degree of a crime rather than negate guilt, will rarely satisfy Scarborough’s third factor unless they substantially alter sentencing exposure.
• Structured Remand Expectations. Trial courts must follow Reed in explicitly discussing each Scarborough element; failure to do so invites appellate remand.
• Plea-Stage Defense Strategy. Defense counsel are on notice that ignoring a client’s request to attempt withdrawal can constitute deficient performance, but relief will still require a compelling innocence narrative.

Complex Concepts Simplified

• Guilty But Mentally Ill (GBMI). The defendant admits guilt but is also adjudged mentally ill; the conviction stands, and the defendant receives treatment during incarceration.
• Strickland Prejudice. Not every lawyer error justifies relief; the mistake must have probably changed the outcome.
• Scarborough Factors. Five questions Delaware judges ask to decide if a guilty plea should be allowed to be withdrawn before sentencing.
• Extreme Emotional Distress (EED). A partial defense that can reduce first-degree murder to manslaughter if the defendant proves he acted under a powerful, mitigating emotional state.

Conclusion

Smith v. State re-affirms that while deficient performance in the plea-withdrawal context is serious, post-conviction relief turns on a rigorous demonstration of prejudice under Strickland. The Delaware Supreme Court has now clarified that: (1) “legal innocence” demands evidence, not conjecture; (2) purely sentencing-level mitigations like EED ordinarily do not advance the innocence factor; and (3) a knowing, voluntary plea retains powerful finality even when counsel falters afterwards. Practitioners must therefore compile a concrete factual record before alleging innocence and be prepared for strict appellate scrutiny. The ruling is poised to influence Delaware plea-withdrawal practice and underscores the judiciary’s commitment to balancing individual rights with the integrity of guilty pleas.
