What is the current state of the law on sex offender classification?

Under certain circumstances, labeling a prisoner with a particular classification may implicate a liberty interest subject to the protections of due process. Neal v. Shimoda, 131 F.3d 818, 827 (9th Cir. 1997) ("[T]he stigmatizing consequences of the attachment of the 'sex offender' label coupled with the subjection of the targeted inmate to a mandatory treatment program whose successful completion is a precondition for parole eligibility create the kind of deprivations of liberty that require procedural protections.").
