Whether a reasonable-doubt instruction that is unconstitutional under Cage v. Louisiana denies the defendant the Sixth Amendment right to a jury trial.
Holding
Yes. An instruction that permits conviction without a proper finding of guilt beyond a reasonable doubt deprives the defendant of the jury verdict required by the Sixth Amendment.
Reasoning
The Sixth Amendment guarantees a criminal defendant a jury determination of guilt. That guarantee is not satisfied by a jury finding that the defendant is probably guilty followed by a judicial determination that the evidence establishes guilt beyond a reasonable doubt. The constitutionally required verdict is a jury verdict of guilty beyond a reasonable doubt.
Due process requires the prosecution to prove every element of the charged offense beyond a reasonable doubt. The Court treated Cage as controlling, and Cage establishes that the instruction given here did not ensure that the jury applied that constitutionally required standard. Consequently, the jury did not return the kind of valid guilty verdict that the Sixth Amendment demands.
