A sex offender has filed a lawsuit against the City of South Lake Tahoe, claiming the city's sex offender ordinance violates pre-existing state and federal laws.

The sex offender laws in South Lake Tahoe require registered sex offenders to keep 300 feet away from areas like schools, parks, bus stops, arcades and swimming pools.

Janice Bellucci is the president of the California Reform Sex Offender Laws organization. She says, 'If you were to interpret it literally, there are places they couldn't drive down the street and other places they couldn't go - to coffee shops - or they couldn't get their laundry done at the laundromat.' Bellucci says state and federal laws already address what sex offenders can and can't do.

'The laws that have been passed by the city of South Lake Tahoe are actually preempted by state law,' she says. 

The California Court of Appeal ruled in January that the sex offender laws in the City of Irvine and Orange County were invalid due to pre-existing state laws.
