Shockley v. Vandergriff
In brief
The Supreme Court declined review (denied the petition), so it did not decide whether Shockley had a right to appeal or whether his lawyer provided constitutionally inadequate help.
- Where it stands
- Decided
Decided · March 31, 2025 · Opinion by Justice Sotomayor
- What it’s about
- This case involves a habeas corpus petition where the petitioner argued his legal counsel was ineffective for failing to call witnesses during a mistrial hearing. The lower courts previously held that counsel's performance was not constitutionally deficient.
- Who it affects
- The Court’s refusal to hear the case leaves the lower-court outcome in place for Shockley, but it does not endorse that outcome or decide the legal questions. He received no Supreme Court ruling on his appeal request or his lawyer’s performance.
