Lewis v. English

Whether a federal prisoner may file a petition for habeas corpus under 28 U.S.C. § 2241 in order to raise arguments that were foreclosed by binding (but erroneous) circuit precedent at the time of his direct appeal and original application for post-conviction relief under 28 U.S.C. § 2255, but which are meritorious in light of a subsequent decision overturning that erroneous precedent.
