An inmate such as plaintiff who fails to show "that his release on parole or supervised release is actual or imminent" yet claims that he will be deprived of his due process rights has merely asserted a speculative injury insufficient to establish standing. Cooper v. Owens, 303 F. App'x 179, 180 (5th Cir. 2008); see also Clarke v. Director, TDCJ-CID, No. 4:09-CV-404, 2012 WL 4120430, at *3 (E.D. Tex. Sept. 19, 2012) (holding that the inmate's alleged injury was speculative and did not satisfy the standing requirement because he had not shown that his release on parole was actual or imminent). It has long been held that, in order to bring a challenge to the constitutionality of a statute, a claimant must have standing to raise the claim.
