What it's about
He also asks whether refusing that instruction until the judge’s final directions is an error that automatically requires a new trial (structural error).
The dispute concerns when jurors must hear instructions about the presumption of innocence and the state's burden of proof in a criminal trial.
Question presented
1. Whether the Sixth and Fourteenth Amendments require a criminal jury, on request, to be instructed on the presumption of innocence and the burden of reasonable doubt before the presentation of evidence? 2. Whether refusal to give an instruction, on request, on the presumption of innocence until final instructions is structural error, overruling Kentucky v. Whorton, 441 U.S. 786 (1979)?
