WASHINGTON — Supreme Court justices questioned Wednesday the fairness of “Megan’s Law” as they heard arguments in two cases, at issue are whether such laws amount to a second punishment for those already convicted for their crimes, and whether the laws violate an offender’s due process rights.

“Megan’s law” requires Sex offenders and certain other types of felons to register with local authorities after they are released from prison, and such information is typically available to the public.

Supporters of these laws argue registration laws are not unfair because the convictions are already a matter of public record.

Opponents of the law argue registrations laws prevent those convicted from moving on with their lives after serving their time, calling them “government-imposed stigma.
