It was unconstitutional to retroactively apply Michigan’s SORA to a defendant who had pleaded guilty to a sex offense under a state diversionary statute, the Michigan SCT has ruled.

In a recent opinion, the US Court of Appeals for the 6th Circuit declared recent amendments to Michigan's SORA to be ex post facto law.

In In re TD, the COA held that application of SORA was not "punishment," so it could not be deemed unconstitutional on grounds that it was cruel and unusual as applied to the respondent.

In People v Dowdy, the Court of Appeals issued a published opinion interpreting SORA - the Sex Offender Registry Act.
