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 acquittal by reason of mental disease or defect and resulting prolonged confinement. It held that retroactive relief based on a constitutional requirement that such a plea be knowing and voluntary was barred because that requirement would constitute a new rule that did not qualify for the watershed exception. It also held that the petitioner failed to prove that trial counsel performed deficiently by misadvising him about the possibility of confinement beyond twenty-five years.
