D.C. Super. Ct. Crim. R. 48

(a) By the Government.

(1) Information or Complaint. The government may file a dismissal or nolle prosequi

of an information or complaint. Such a dismissal is without prejudice unless otherwise

stated. The government may not dismiss the prosecution during trial without the

defendant’s consent.

(2) Indictment. The government may, with leave of court, dismiss an indictment.

Such a dismissal is without prejudice unless otherwise stated. The government may not

dismiss the prosecution during trial without the defendant’s consent.

(b) By the Court. The court may dismiss an indictment, information, or complaint if

unnecessary delay occurs in:

(1) presenting a charge to a grand jury;

(2) filing an information against a defendant; or

(3) bringing a defendant to trial.

(c) Abandonment of Prosecution.

(1) Determination of Abandonment. If any defendant charged with a criminal offense

is committed or held to bail to await the action of the grand jury and after nine months

the grand jury has not taken action, either by ignoring the charge or by returning an

indictment, the prosecution of such charge must be deemed abandoned and the

defendant must be set free or have the bail discharged.

(2) Enlargement of Time. The court may enlarge the time for taking action by the

grand jury when practicable, so long as good cause for enlargement is shown in writing,

and due notice is given to the defendant.
