U.S. Sup. Ct.;
16-240

When petitioner was tried in a Massachusetts trial court, the courtroom could not accommodate all the potential jurors. As a result, for two days of jury selection, an officer of the court excluded from the courtroom any member of the public who was not a potential juror, including petitioner's mother and her minister. Defense counsel neither objected to the closure at trial nor raised the issue on direct review. Petitioner was convicted of murder and a related charge. Five years later, he filed a motion for a new trial in state court, arguing, as relevant here, that his attorney had provided ineffective assistance by failing to object to the courtroom closure. The trial court ruled that he was not entitled to relief. The Massachusetts Supreme Judicial Court affirmed in relevant part. Although it recognized that the violation of the right to public trial was a structural error, it rejected petitioner's ineffective-assistance claim because he had not shown prejudice.
