Tompkins, a prisoner under sentence of death and under an active death warrant, appeals from the trial court's orders denying motions to vacate his sentence under Florida Rule of Criminal Procedure 3.851.*fn1 Tompkins also petitions to invoke this Court's authority to issue all writs necessary to complete the exercise of its jurisdiction, or alternatively to issue a writ of habeas corpus, or both. Because the orders concern post-conviction relief from a sentence of death, this Court has jurisdiction of the appeal under article V, section 3(b)(1), Florida Constitution. Additionally, we have jurisdiction over the petition under article V, sections 3(b)(7) and 3(b)(9), Florida Constitution. For the reasons stated in this opinion, we affirm the trial court's orders and deny Tompkins's petition for all writs and habeas relief.
