Standing will be the issue.
I hope plaintiffs considered to consequences of entering into plea agreement knowingly waived right to contest civil action.
The information provided via SOR regime is for the people’s use. That aspect is essentially civil in intent.
IMHO the punitive outcome results from the people’s uses outside that aspect. The people clearly use the info to impose their own brand of affirmative disability and restraint, residency restriction, banishment and so forth. Putting legal bars around places ( presumptively where kids gather) is no different than placing offenders in jail or prison.
