Martin v. Kansas Parole Bd.
Annotate this CaseLouie Martin, a convicted felon, was released on postrelease supervision after incarceration. Shortly after his release, the legislature passed an amendment that impacted Martin's previously imposed postrelease expiration date by extending it nearly eleven years. Martin filed a petition for writ of habeas corpus against the parole board, claiming that the change in his postincarceration supervision discharge date is an unlawful ex post facto law. The district court dissolved Martin's writ of habeas corpus and dismissed the case. The Supreme Court reversed, holding that (1) because the period of parole or postrelease supervision is part of the sentence imposed, a change to that period is a change in punishment for ex post facto considerations; (2) because the amendment is retrospective and changes the term of postrelease supervision, the law violates ex post facto protections if it acts to Martin's detriment; and (3) Martin was clearly disadvantaged by the amendment. Therefore, the amendment is an impermissible ex post facto law as applied to Martin.
