People v. Corneliusgreen2 sentences2016See Adams, 144 Ill. 2d at 387-89 (the duty to register under SORA did not constitute punishment as the law had the non-penal purpose of protecting children from sexual crimes and aiding law enforcement in monitoring sexual offenders); Malchow, 193 Ill. 2d 23 1-15-3047 at 419-24 (rejecting the defendant's ex post facto challenge to SORA and the Notification Law and finding that their intent was protection of the public, not punishment); Cornelius, 213 Ill. 2d at 207-09 (holding that the amendment to the Notification Law providing for dissemination of sex offender information on the Internet did 2014App. 3d 405, 409 (2008) (citing People v.

California, 539 U.S. 607, 632 (2003), where the Supreme Court declared a California statute that allowed for the prosecution of time- barred cases to be an ex post facto violation, but “to hold that such a law is ex post facto does not prevent the State from extending time limits for the prosecution of future offenses, or for prosecutions not yet time barred.” ¶ 28 Here, defendant committed this offense on April 26, 2008, and under the general statute of limitations in effect at that time, the limitation period for his pros 2022See Stogner, 539 U.S. at 632 (stating that laws extending the statute of limitations after it has expired violate the ex post facto clause of the United States Constitution but, conversely, the ex post facto clause does not prevent the State from extending the statute of limitations for crimes that are not time-barred); see also Anderson, 53 Ill. 2d at 440 ; see also People v.

United States Parole Comm’n, 594 F.2d 170, 175 (7th Cir. 1979), the Seventh Circuit held that the “deprivation of all opportunity to be released on parole also comes within the scope of [the ex post facto] clause.” Like the accrual of CGCs, being paroled is not a certainty. 1980Appellant also contends that the cases of Rodriguez v.

(3d Cir. 1978), 579 F.2d 238 , mandate a finding that the rules of the Prisoner Review Board and section 3—3—5(c)(2) of the Unified Code of Corrections worked to his substantial disadvantage and were applied retroactively in violation of the ex post facto clause of the Federal Constitution. | 2 | 3 |

Beazell v. Ohio
green
2 sentences1985Ed. 216, 217 , 46 S. Ct. 68, 68 , defined as ex post facto law: “It is settled, by decisions of this Court so well known that their citation may be dispensed with, that any statute which punishes as a crime an act previously committed, which was innocent when done; which makes more burdensome the punishment for a crime, after its commission, or which deprives one charged with crime of any defense available according to law at the time when the act was committed, is prohibited as ex post facto.” However, where the crime, the punishment and the degree of proof necessary to establish guilt remain 1983Ed. 216 , 46 S. Ct. 68 ), we believe this case presents the question of whether a statute which merely makes the assertion of certain defenses less desirable than they would have been at the time of an offense is violative of the ex post facto doctrine. | 10 | 1983–2003 |
Weaver v. Graham

2 sentences2021Defendant analogized this case to Weaver v. Graham, 450 U.S. 24 (1981), where the Supreme Court determined Florida’s “gain time” credits altered the punitive consequences for prisoners and therefore violated the ex post facto clause. 1998Foremost among the concerns of the ex post facto clause are “the lack of fair notice and governmental restraint when the legislature increases punishment beyond what was prescribed when the crime was consummated.” Weaver, 450 U.S. at 30 , 67 L. | 6 | 1986–2021 |

And the Court of Appeals for the Sixth Circuit held in Dale v. Haeberlin, 878 F.2d 930, 934 (6th Cir.1989), that "the right to due process prevents judicially wrought retroactive increases in levels of punishment in precisely the same way that the ex post facto clause does when the changes are produced by legislation."
