Who it affects

What it's about

Those results were before the federal court only because Florida had raised a separate argument that habeas relief was not required by “law and justice.”

The case is part of a broader debate over how strictly federal courts must defer to state criminal judgments.

Question presented

The question presented is whether the Eleventh Circuit was correct that the Florida Supreme Court’s finding of overwhelming evidence against petitioner was reasonable under AEDPA’s deferential standard of review.
