This section applies only to pretrial appeals. The provisions of § 19.2-243 shall not apply to the period of time commencing when the Commonwealth’s notice of pretrial appeal is filed pursuant to this chapter and ending 60 days after the Court of Appeals or Supreme Court issues its mandate disposing of the pretrial appeal. Such finality of the Court of Appeals’ decision shall not preclude a defendant, if he is convicted, from requesting the Court of Appeals or Supreme Court on direct appeal to reconsider an issue which was the subject of the pretrial appeal.
