That’s because there isn’t any. They are just trying to prevent pre-Sorna people from being able to leave early. Or so that how it goes in their mind. They believe they can make ex post facto laws because the registry is civil in their mind.
What changes did the make from SORNA to ACT 10 anyways to make it “civil” . The only thing I saw was the ability to fight your SVP status after 25 years and whether or not your charge qualifies for the registry. Oh and the ability to call in after 3 years , yet for only certain pieces of information.
