A service member who is convicted at a court-martial and believes the defense attorney failed them can raise ineffective assistance of counsel on appeal. Military appellate courts take the claim seriously, but they apply a demanding, well-defined standard borrowed from civilian constitutional law and refined for the military context. Understanding how those courts evaluate the claim explains why some succeed and many do not.
The constitutional source: the right to effective counsel
The Sixth Amendment right to counsel includes the right to the effective assistance of counsel, and that protection applies to service members at courts-martial. The governing test comes from the Supreme Court’s decision in Strickland v. Washington, 466 U.S. 668 (1984), which set a two-part standard for judging when a lawyer’s performance is so deficient that it violates the constitutional guarantee. Military courts have expressly adopted Strickland.
The two prongs: deficient performance and prejudice
Under Strickland, an appellant must prove two things. First, that counsel’s performance was deficient, meaning the representation fell below an objective standard of reasonableness. Second, that the deficient performance prejudiced the defense, meaning there is a reasonable probability that, but for counsel’s errors, the result of the proceeding would have been different. Both prongs must be satisfied. If the appellant cannot show prejudice, a court need not even decide whether performance was deficient, and the reverse is true as well.
The Court of Appeals for the Armed Forces applies this same two-part framework. In United States v. Gooch, 69 M.J. 353 (C.A.A.F. 2011), the court reaffirmed that to prevail on an ineffective assistance claim an appellant must demonstrate both that counsel’s performance was deficient and that the deficiency resulted in prejudice. The military’s adoption of the Strickland standard is long-settled; in United States v. Polk, 32 M.J. 150 (C.M.A. 1991), the court articulated the framework that military appellate practice continues to follow.
How the deficiency prong is applied
The first prong is difficult to meet because courts indulge a strong presumption that counsel’s conduct fell within the wide range of reasonable professional assistance. Appellate courts do not second-guess strategy with the benefit of hindsight. A choice not to call a particular witness, not to pursue a certain defense theory, or not to object at a given moment is ordinarily treated as a tactical judgment, and tactical judgments are virtually unchallengeable when they are informed and reasonable. The appellant must overcome the presumption and show that the attorney’s act or omission was not sound strategy but a genuine lapse below professional norms.
To assess this, military courts often look beyond the trial record. Because the reasons behind counsel’s choices may not appear on the face of the transcript, appellate courts frequently order the defense counsel to provide an affidavit explaining what they did and why. The appellant may submit a competing affidavit. When the affidavits conflict on a material point, the court must decide whether the dispute can be resolved on the written submissions or whether a fact-finding hearing is required.
The DuBay hearing for factual disputes
When an ineffective assistance claim turns on contested facts that cannot be resolved from the record and affidavits, military appellate courts can order a post-trial evidentiary hearing, commonly called a DuBay hearing, named for the case that established the procedure. A military judge takes testimony, makes findings of fact, and returns the record to the appellate court. This mechanism lets the appellate court evaluate what counsel actually did and why before applying the Strickland prongs, and it is a distinctive feature of how the military handles these claims.
How the prejudice prong is applied
Even a clearly deficient performance does not warrant relief unless it changed, or reasonably could have changed, the outcome. The appellant must show a reasonable probability of a different result, which the Supreme Court defined as a probability sufficient to undermine confidence in the outcome. This is more than showing the error had some conceivable effect, but less than showing it more likely than not altered the verdict. In a court-martial, prejudice can relate to findings, for example a different verdict, or to sentence, for example a materially lighter punishment had counsel performed adequately at the sentencing phase.
The strength of the government’s case heavily influences the prejudice analysis. Where the evidence of guilt was overwhelming, even a serious attorney error is unlikely to undermine confidence in the result. Where the case was close, a smaller error can be enough.
The standard of review on appeal
Military appellate courts review ineffective assistance claims de novo, treating the ultimate question as a mixed question of law and fact. They give appropriate deference to any subsidiary findings of historical fact, especially those made by a military judge at a DuBay hearing, but they decide independently whether the established facts amount to deficient performance and prejudice under Strickland. This de novo posture means the appellate court does not simply defer to the trial outcome on the legal question of effectiveness.
How the claim is raised and reviewed
An ineffective assistance claim ordinarily reaches the service Court of Criminal Appeals first, on direct appeal, where that court has broad authority to review the record and may order affidavits or a DuBay hearing. The Court of Appeals for the Armed Forces may then review the claim if it grants a petition. Because the claim often depends on matters outside the trial record, it is sometimes better developed through post-trial submissions than through the cold transcript alone. Appellate defense counsel typically identify the specific acts or omissions, gather supporting evidence, and frame the argument around both Strickland prongs rather than general dissatisfaction with the lawyer.
Why most claims fail, and when they succeed
The combination of the strong presumption of competence and the demanding prejudice requirement means many ineffective assistance claims do not succeed. Claims tend to prevail when counsel did something that no reasonable strategy explains, such as failing to investigate or present clearly available exculpatory evidence, failing to advise on a critical decision, or laboring under an actual conflict of interest, and when that failure plausibly affected a close result. Claims tend to fail when the challenged conduct is reasonably characterized as strategy or when the evidence of guilt was so strong that the error could not have changed the outcome.
Bottom line
In military justice, ineffective assistance of counsel is evaluated under the two-part Strickland v. Washington standard, requiring proof that counsel’s performance was deficient and that the deficiency prejudiced the defense, as the Court of Appeals for the Armed Forces confirmed in cases such as United States v. Gooch and earlier in United States v. Polk. Courts apply a strong presumption of competence, often develop the facts through counsel affidavits or a DuBay evidentiary hearing, and review the ultimate question de novo. Relief follows only where a genuine lapse in representation undermines confidence in the verdict or sentence.
