A divided federal appeals court in Virginia has ruled that residents of a mobile home park outside Washington, D.C., may proceed with claims that the owners of the park wrongly required them to show proof of legal U.S. residency before renewing their leases.

In a 2-1 ruling, the U.S. Court of Appeals for the Fourth Circuit majority said the plaintiffs made a sufficient showing that the policy had a “disparate impact” on the park’s Latino population.
