In Buck v. Thaler, defendant claimed a constitutional violation based on comments about race by an expert witness. One small problem, as pointed out by Justice Alito joined by Justices Scalia and, notably, Breyer:
Dr. Quijano's testimony would provide a basis for reversal of petitioner's sentence if the prosecution were responsible for presenting that testimony to the jury. But Dr. Quijano was a defense witness, and it was petitioner's attorney, not the prosecutor, who first elicited Dr. Quijano's view regarding the correlation between race and future dangerousness.The court took up the juvenile LWOP cases, previously noted here. A simple grant after so many relists is unusual, but it does happen.
