A Maryland state court ruled Thursday that a referendum on the Maryland Dream Act will be on the November ballot. In 2011, Maryland lawmakers approved the legislation to let undocumented students pay in-state tuition at state colleges so long as they attended Maryland high schools for at least three years and their parents or guardians have filed taxes. Immigration advocates made one last attempt to stop the referendum on Tuesday, arguing before the court of appeals that the Dream Act is a fiscal issue and ineligible for referendum. The law’s supporters, including Gov. Martin O’Malley (D), are building a campaign to push for voters to affirm the law.
