A Life Sentence and the Right to Present a Complete Defense
Law Offices of David P Sheldon Asks Supreme Court to Review Excluded Defense Evidence in Navy Murder Case
A petition challenging a life-without-parole conviction asks whether excluding evidence central to the defense violated the constitutional right to present a complete defense.
WASHINGTON, D.C. — The Law Offices of David P. Sheldon, PLLC has filed a petition asking the U.S. Supreme Court to review a Navy court-martial conviction that resulted in a sentence of life without parole. The filing raises a question at the heart of a fair trial: whether an accused service member was denied the right to present a complete defense when the military judge excluded messages the defense says were critical to explaining the death at issue.
The petition in Becker v. United States challenges the exclusion of messages written by the deceased months before her death. The defense sought to use those messages to support its theory that she died by suicide. The prosecution argued that the Navy lieutenant murdered her, and the court-martial panel convicted him of premeditated murder, among other offenses.
The filing asks the Supreme Court to examine whether the evidentiary ruling crossed a constitutional line. David P. Sheldon, founder of the Law Offices of David P. Sheldon, PLLC, is counsel of record on the petition.
Evidence the Panel Did Not Hear
The case arose from a woman’s fatal fall from an apartment window in Belgium in October 2015. At trial, the parties presented competing accounts of what happened. At trial, prosecutors repeatedly offered testimony that she had not shown suicidal intent, while the defense presented expert testimony that she faced an elevated risk of suicide.
The defense also sought to introduce messages sent seven months before the death. Those messages expressed fear about losing memory and mental faculties. The petition argues that her own words offered evidence the panel needed to weigh the defense theory and assess the prosecution’s account.
The military judge excluded the messages on hearsay grounds and under Military Rule of Evidence 403, which allows certain relevant evidence to be excluded after weighing its value against specified risks to the trial.
Errors Recognized but the Exclusion Upheld
On appeal, the Navy-Marine Corps Court of Criminal Appeals found that the messages should have qualified for a hearsay exception covering a person’s then-existing mental or emotional condition. It also found error in the trial judge’s Rule 403 reasoning.
The appellate court nevertheless upheld the exclusion after conducting its own analysis. It found that the messages had limited value, risked confusing the issues because they concerned a mental state seven months earlier, and repeated a point already addressed by the defense expert. The court also concluded that the exclusion caused no prejudice because the defense had introduced substantial evidence about the deceased’s mental health history.
The Supreme Court petition challenges that conclusion. It argues that the messages were central to the defense and that expert testimony did not replace the opportunity for the panel to consider the deceased’s own statements.
The Constitutional Question
The petition also argues that the prosecution and defense faced unequal standards. According to the filing, the prosecution was allowed to present testimony about the deceased’s lack of suicidal intent across many years, while the defense’s messages were excluded in part because they were seven months old.
Relying on Supreme Court decisions including Chambers v. Mississippi and Holmes v. South Carolina, the petition argues that applying evidence rules in this way deprived the lieutenant of his Sixth Amendment right to present a complete defense. It asks the Court to bring the military courts’ treatment of that right into line with the Supreme Court’s precedents and decisions from federal appellate courts.
For the service member challenging this conviction, the stakes are life without parole. The filing also raises a broader concern for military defendants: whether they receive a meaningful opportunity to present evidence supporting their account of events when that evidence is disputed by the government.
A Request for Supreme Court Review
The Navy-Marine Corps Court of Criminal Appeals issued its decision on December 17, 2025. The Court of Appeals for the Armed Forces denied review on June 22, 2026, and denied reconsideration on July 27, 2026.
The petition now asks the Supreme Court to grant a writ of certiorari, meaning to agree to review the case. Filing the petition does not mean the Court has agreed to hear it or ruled on its merits. The conviction remains in place, and the petition’s constitutional claims are arguments presented for review.
Through this filing, the Law Offices of David P. Sheldon, PLLC seeks Supreme Court scrutiny of an evidentiary decision it argues prevented the court-martial panel from fully evaluating the defense.
