Fortunately, Karlton has clarified Jessica’s Law so it can start protecting the state’s children without trampling the Constitution. IT’S against the law, not to mention all reason, to apply retroactive punishment to people who have already served their terms. If lawmakers decide that, say, the minimum sentencing for car thieves is too low and double it, that’s fine. But they can’t then order the rounding up of convicted car thieves who have already served their time and throw them back in jail. That is why U.S. District Judge Lawrence Karlton’s ruling last week on Proposition 83, Jessica’s Law, was correct. Karlton affirmed that the new law, which limits where sex offenders can live and subjects them to GPS monitoring, doesn’t apply to previously registered offenders. The measure’s language itself never indicated a retroactive nature. Indeed, if it had, the clear unconstitutionality would have likely caused enough controversy to kill it. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
