John Does v. Richard Snydergreen2 sentences2018The Snyder court conducted the two-step inquiry that the Supreme Court applied when analyzing whether Alaska’s SORA violated the Ex Post Facto Clause. “[T]he test we must apply . . . is quite fixed: an ostensibly civil and regulatory law, such as SORA, does not violate the Ex Post Facto clause unless the plaintiff can show ‘by the clearest proof’ that ‘what has been denominated a civil remedy’ is, in fact, ‘a criminal penalty,’ ” Id. at 700 , citing Smith, 538 US at 92 . 2017He based his argument on the Sixth Circuit Court of Appeals’ decision in Does #1-5 v Synder, 834 F3d 696, 705-706 (CA 6 2016), cert den ___ S Ct ___ (2017), which held that SORA registration constitutes punishment for purposes of the ex post facto clause of the United States Constitution, and so the 2006 and 2011 amendments to SORA could not be constitutionally applied to those convicted prior to their effective dates. | 1 | 5 |

Kansas v. Hendricksgreen1 sentence2024The dissent’s references to a “sham” are from Justice Kennedy’s concurring opinion in Hendricks, where he commented in the context of an ex post facto analysis that if the relevant statute “were adopted as a sham or mere pretext, there would have been an indication of the forbidden purpose to punish.” Hendricks, 521 US at 371 (Kennedy, J., concurring). | 1 | 1 |
