Gov. Gray Davis [of California] signed legislation Sunday to give Mexican workers more time to recover wages they say were denied them when they came to the United States to work during World War II...The law is intended to help "braceros," the more than 300,000 Mexican farm workers who were contracted by the U.S. government to relieve the labor shortage during World War II...The guest workers and their heirs in 2001 sued the U.S. and Mexican governments and Wells Fargo Bank to recover the money. A U.S. District Court judge dismissed much of the suit in August, but workers' attorneys say they will continue to try to pursue the case.
