Grand Jury Proceedings in Washington, D.C.: What Defendants Need to Know

What Is a Grand Jury?

A grand jury is a group of citizens who consider evidence presented by prosecutors and determine whether criminal charges should be formally brought through an indictment.

Under D.C. Superior Court Criminal Rule 6, a grand jury generally consists of 16 to 23 members.

For an indictment to be returned, at least 12 grand jurors must agree that the charge should proceed.

An indictment does not mean that the defendant has been found guilty. It means the grand jury has determined that there is a sufficient legal basis for the government to formally prosecute the charges contained in the indictment.

When Is a Grand Jury Required in D.C.?

Under D.C. Code § 23-301, an offense punishable by imprisonment for more than one year generally must be prosecuted by indictment.

A defendant may waive indictment in certain circumstances after being advised of the charge and applicable rights. If indictment is properly waived, prosecution may instead proceed by information.

Because most serious felony prosecutions involve potential incarceration exceeding one year, grand jury proceedings frequently play an important role in D.C. criminal cases.

What Happens During Grand Jury Proceedings?

Grand jury proceedings differ significantly from a trial.

Prosecutors present evidence and question witnesses before the grand jury. Evidence may include:

• Police officer testimony

• Civilian witness testimony

• Surveillance footage

• Physical or forensic evidence

• Phone and digital records

• Financial documents

• Photographs or videos

• Statements allegedly made by the accused

The defense generally does not present its case in the same adversarial manner used at trial.

Under Rule 6, only specified people may be present while the grand jury is in session, including government attorneys, the witness being questioned, necessary interpreters, and personnel responsible for recording the proceeding.

Only the jurors may be present during deliberations and voting.

Are Grand Jury Proceedings Secret?

Yes. Grand jury proceedings are generally subject to strict secrecy requirements.

Rule 6 limits disclosure of matters occurring before the grand jury, although the court may authorize disclosure in specific circumstances.

Proceedings are generally recorded except during grand-jury deliberations and voting.

These secrecy rules are one reason defendants may have limited information about exactly what occurred before the grand jury when an indictment is first returned.

Can a Defendant Challenge an Indictment?

An indictment does not end the defense’s ability to challenge the government’s case.

Depending on the circumstances, a defense attorney may examine issues involving:

• Whether the grand jury was lawfully selected

• Whether the indictment properly states an offense

• Constitutional violations

• Illegal searches or seizures

• Inadmissible statements

• Identification problems

• Discovery and evidentiary weaknesses

Rule 6 also permits certain objections concerning the legal qualification or selection of grand jurors.

However, challenges to indictments are governed by specific procedural rules and must be evaluated based on the facts of the individual case.

What Happens After a Grand Jury Returns an Indictment?

If at least 12 grand jurors concur, the indictment is returned to the court.

In a felony case, the defendant will generally proceed to an arraignment on the indictment, where the charges are formally addressed and a plea is entered.

The case may then move through discovery, pretrial motions, plea negotiations, hearings, and potentially trial.

An indictment is therefore an important procedural step, but it is not a conviction.
