Robert Mitchell Jennings won.
A federal district court granted habeas relief because Jennings' trial counsel failed to present evidence of his possible brain abnormalities and his disadvantaged background. The district court, however, didn't agree with his argument about his attorney's concessions during closing arguments.
The government appealed, the Fifth Circuit reversed, and refused to consider the capital concession argument, labeling it procedurally defaulted. The Supreme Court granted certiorari in the case earlier today.
