Va. Code Ann. § 15.2-2655

Upon motion of the plaintiff or the issuer, the court in which the first proceeding to invalidate or sustain the bonds was instituted may enjoin the commencement by any person, corporation, or association of any other action or proceeding involving the validity of the bonds or any matter recited in the motion for judgment. The court may order a joint hearing before it of all issues then pending in any actions or proceedings in any court in the Commonwealth, may order all such actions or proceedings consolidated with the validation proceeding pending before it, and may make such orders as may be necessary or proper to effect consolidation and as may tend to avoid unnecessary costs or delays. Such orders shall not be appealable.
