What it's about

The Supreme Court did not decide whether the lawyer was ineffective; it ruled that federal limits on relief for state prisoners apply even when a state court gives no reasons, wiped out the Ninth Circuit’s ruling, and sent the case back (reversed and remanded).

The case concerns how federal courts review state-court decisions when the state court gives no explanation.

Question presented

What did Justice Ginsburg say about the lawyer's failure to consult blood experts?
She agreed that the lawyer failed to provide the representation the Constitution guarantees, but said Richter's supporting evidence did not weaken the prosecution's case enough to make the trial unfair and unreliable.
