Constitutionality of sex offender registriesin the United States The National Association for Rational Sexual Offense Laws (NARSOL) is an organization headquartered in Raleigh, North Carolina with operations based in Albuquerque, New Mexico and with affiliated organizations, advocates, and contacts in the vast majority of states.

NARSOL has generated media attention by arranging national conferences in multiple cities including Boston, Albuquerque,[1] Los Angeles[2] Dallas,[3] Atlanta, Cleveland, Houston, and Raleigh, and by being involved in numerous lawsuits challenging the constitutionality of sex offender registration and notification laws.

NARSOL's former Californian chapter, CA RSOL, challenged ordinances governing registered sex offenders in federal court across the state of California.

[15] These efforts culminated in March 2015 when Supreme Court of California declared residency restrictions unconstitutional citing their unfairness and counterproductive effects.

They were part of the Amicus Curiae cited in the March 2013 Court of Appeals decision Doe v. DPSCS which declared that Maryland's existing sex offender registry laws are punitive in effect, and therefore could not constitutionally be applied retroactively to persons whose crimes pre-dated registration.
