Va. Code § 19.2-200
The grand jury shall inquire of and present all felonies, misdemeanors and violations of penal laws committed within the jurisdiction of the respective courts wherein it is sworn; except that no presentment shall be made of a matter for which there is no corporal punishment, but only a fine, where the fine is limited to an amount not exceeding five dollars. After a regular grand jury has concluded its deliberation on bills of indictment and made its return thereon, the court shall inquire of it whether it recommends that a special grand jury be impanelled to perform any of the functions provided for in subdivision (2) of § 19.2-191. If a majority of the grand jurors responds in the affirmative, the court shall impanel so many of that jury as answer in the affirmative and are also willing to serve thereon, plus any additional members as may be necessary to complete the panel, as a special grand jury and if a minority of the grand jurors responds in the affirmative, the court may impanel a special grand jury in the same manner.
