Sasser v. Payne

(1) Whether amending a petition for writ of habeas corpus after a remand by an appellate court makes it a second-or-successive application under 28 U.S.C. § 2244; and (2) whether, when deciding whether a defendant is intellectually disabled and thus ineligible for the death penalty, courts violate the Eighth Amendment by a) weighing strengths against deficits in the same adaptive-skills domain, or b) requiring that a defendant prove adaptive deficits at time periods beyond those defined by medical standards.
