(AP) - A judge in Northern California is set to hear arguments over whether to block a new federal law that requires sex offenders to have "unique identifiers" in their passports.
U.S. District Court Judge Phyllis Hamilton has scheduled a hearing Wednesday in Oakland on a nonprofit group's request for a preliminary injunction against the so-called International Megan's Law, which President Barack Obama signed into law in February.
The law requires the Secretary of State to add "unique identifiers" to the passports of registered sex offenders.
The group, California Reform Sex Offender Laws, has filed a lawsuit challenging the law. It says a symbol on a passport identifying people as registered sex offenders violates their constitutional rights and puts them and others traveling with them in danger.
