Reading slowly and deliberately from a prepared statement, Judge Emmet Sullivan of the federal trial court in Washington, D.C., questioned whether prosecutors in a high-profile drug trafficking case violated the D.C. Rules of Professional Conduct by making false statements to the court or failing to correct false statements.

A little background: prosecutors last week moved to dismiss the conspiracy case against businessman Zhenli Ye Gon, accused in an international drug trafficking scheme with roots in Mexico and China. Last week in court, Sullivan had a lot of questions about the sudden decision to dump the case. Sullivan said Wednesday he will grant the government’s request.
