Va. Code § 17.1-116
Whenever, by reason of the destruction, possession by a public enemy, or infection with contagious disease of any building in which the Supreme Court is to be held, it seems necessary to the Chief Justice, he shall, by proclamation, designate a place at which the Court shall be held, so long as such reason may continue, and when the circumstances require it, may postpone the time for holding the Court. In the case of the destruction of the building, the place designated by the Chief Justice shall be within the same county, city or town as the destroyed building. A copy of such designation shall be sent to the clerk and to each of the justices of the Court and published in some newspaper at the seat of government and near the regular place of session of the Court.
