AN ACT CONCERNING ADDRESS VERIFICATION REFORMS FOR REGISTRANTS.
This bill reformers address verification requirements for individuals required to register under Connecticut sex offender laws, including those convicted of sexually violent offenses. It reduces penalties for failing to report changes in name, address, or status from a class D felony to a C misdemeanor, and allows charges to be dismissed if the person corrects the violation within 20 business days of arraignment and has no prior convictions. The legislation also establishes an affirmative defense for those unable to comply due to uncontrollable circumstances and requires the state to mail address verification forms within five business days upon request. These changes aim to make the registration process more manageable while maintaining oversight of registrants.

MINOR
The bill was renamed from 'Raised Bill' to 'Substitute Bill' to reflect its current status in the legislative process. The most significant substantive change is the replacement of the word 'dismiss' with 'enter a nolle prosequi' in the sections describing how charges are handled when a defendant complies with the law within a specific timeframe. This change alters the legal mechanism for dismissing charges, shifting from an automatic dismissal to a formal prosecutorial decision to drop the case.
ENFORCEMENT
The method for handling charges was changed from 'dismiss' to 'enter a nolle prosequi' for defendants who comply with the law within twenty business days of arraignment, altering the procedural outcome from an automatic dismissal to a formal decision by the prosecutor to not pursue the case.
TECHNICAL
The bill title was updated from 'Raised Bill No. 509' to 'Substitute Bill No. 509' to accurately reflect its current stage in the legislative process.
