Anthony Dyous v. Commissioner of Mental Health and Addiction Services

Summary

The court affirmed the denial of habeas relief on two claims arising from the petitioner's commitment after being found not guilty by reason of mental disease or defect. It held that retroactive recognition of a constitutional requirement that such a plea be knowing and voluntary would constitute a new procedural rule barred by the applicable collateral-review framework and would not qualify for the watershed exception. It also held that the petitioner failed to prove that counsel's performance was objectively unreasonable because the habeas record did not credibly establish that counsel misadvised him about the possibility of confinement beyond twenty-five years.
