SAN FRANCISCO — When the U.S. Court of Appeals for the Ninth Circuit issues a 6-5 decision in an en banc case, the vote often splits along ideological lines. But in an immigration case decided Wednesday, ethnicity appeared to be more of a factor.

Three of the court’s Latino judges helped form the six-member majority which ruled that the children of undocumented immigrants who are granted derivative visas can immigrate to the United States along with their parents, even if they turned 21 while waiting for their parents’ visas to be processed.
