The U.S. Court of Appeals for D.C. on Thursday denied the District’s petition to re-hear its case challenging the constitutionality of the police checkpoint program used in Trinidad in 2008.

The controversial “Neighborhood Safety Zone” checkpoints adopted by D.C. Police Chief Cathy Lanier were first ruled unconstitutional by a three-judge panel on July 10, and this time, a total of seven out of eight judges voted not to grant the District’s petition to re-hear the case en banc. Their decision (you can download the order here) therefore reaffirms the court’s earlier ruling.

This leaves the District with but one remaining appeal: the U.S. Supreme Court. City Desk quotes D.C. AG Peter Nickles as saying he’ll have to “look at our options including a Supreme Court request.”
