                                       ANALYSIS  ¶ 00   On appeal, defendant contends that SORA's statutory scheme violates federal and Illinois  due process rights by infringing on registrants' fundamental liberty interests where it places upon  them severe restrictions, intrusive monitoring and burdensome registration requirements without  providing substantive or procedural due process. In support of this assertion, defendant first  contends that the current version of SORA is punitive in nature. Defendant maintains that  because SORA is punitive and infringes on registrants' fundamental liberty interests without  providing procedural or substantive due process of law, this court should declare it  unconstitutional on its face, and reverse his conviction for failing to register under SORA.  ¶ 00
