In another salvo against the troubled Washington, D.C. courts, a group of lawyers who represent indigent criminal defendants sued the D.C. court system Thursday. The lawyers, who are paid by the courts on an hourly basis for representing the poor, allege that court leaders violated a federal law by failing to process their checks in a timely fashion.

Attorneys Steven Polin, Gary Sidell, and Betty Ballester, as well as investigator Steven Roth, are seeking interest they claim they are owed on overdue vouchers they submitted under the Criminal Justice Act (CJA). The payments are approved by judges in the D.C. Superior Court and the D.C. Court of Appeals.
