Is a prisoner's Fourteenth Amendment claim for access to his central file sufficient to lead to his immediate release?

A prisoner's claim which, if successful, would not necessarily lead to immediate or speedier release falls outside the "core of habeas corpus" and must be pursued in an action brought pursuant to 42 U.S.C. 1983. Nettles v. Grounds, 830 F.3d 922 (9th Cir. 2016). Here, success on petitioner's Fourteenth Amendment claim could result in an order requiring that prison officials allow him access to his central file. It would not necessarily lead to petitioner's immediate or speedier release. For this reason, the petition must be summarily dismissed without prejudice to asserting the claim in a new action pursuant to 1983.
