Companies hoping to compete for a piece of California's $45 billion high-speed rail project would have to disclose whether they transported Holocaust victims or POWs to Nazi camps during World War II.
The state Senate on Thursday voted 31-1 to send AB619 to Gov. Arnold Schwarzenegger's desk.
The bill would require companies seeking contracts with the state's High-Speed Rail Authority to reveal any involvement in transporting people to concentration, prisoner-of-war, labor or extermination camps.
It does not authorize the rail authority to disqualify bidders based on their disclosures.
Supporters of AB619 say they hope it will encourage companies to acknowledge past wrongdoing. Several international railroads have expressed interest in building California's 800-mile rail system.
