A. Where an appearance is required or permitted before a magistrate, intake officer, or, prior to trial, judge, the appearance may be by (i) personal appearance before the magistrate, intake officer, or judge or (ii) use of two-way electronic video and audio communication. With the consent of the court and all parties, an appearance in a court may be made by two-way electronic video and audio communication for the purpose of (a) entry of a plea of guilty or nolo contendere and the related sentencing of the defendant charged with a misdemeanor or felony, (b) entry of a nolle prosequi or dismissal, (c) a revocation proceeding pursuant to § 19.2-306, or (d) waiver of a preliminary hearing. If two-way electronic video and audio communication is used, a magistrate, intake officer, or judge may exercise all powers conferred by law and all communications and proceedings shall be conducted in the same manner as if the appearance were in person. If two-way electronic video and audio communication is available for use by a district court for the conduct of a hearing to determine bail or to determine representation by counsel, the court shall use such communication in any such proceeding that would otherwise require the transportation of a person from outside the jurisdiction of the court in order to appear in person before the court. Any documents transmitted between the magistrate, intake officer, or judge and the person appearing before the magistrate, intake officer, or judge may be transmitted by electronically transmitted facsimile process or other electronic method. The facsimile or other electronically generated document may be served or executed by the officer or person to whom sent, and returned in the same manner, and with the same force, effect, authority, and liability as an original document. All signatures thereon shall be treated as original signatures.
