The U.S. Court of Appeals for the Second Circuit ruled Wednesday that Suffolk County’s decision to contract with a nonprofit to verify the home addresses of registered sex offenders did not violate Fourth Amendment protections against unreasonable searches and seizures.

A unanimous panel of the appeals court upheld the district court’s ruling, which rejected claims from a convicted Level 1 sex offender, who argued that multiple visits from the group Parents for Megan’s Law were unconstitutional.
