(f) Method and imposition of sentence of death. -- The imposition of a sentence of death shall be upon such terms and conditions as the trial court may impose in its sentence, including the place, the number of witnesses which shall not exceed 10, and conditions of privacy, and shall occur between the hours of 12:01 a.m. and 3:00 a.m. on the date set by the trial court. The trial court shall permit one adult member of the immediate family of the victim, as defined in § 4350(e) of this title, or the victim's designee, to witness the execution of a sentence of death pursuant to the rules of the court, if the family provides reasonable notice of its desire to be so represented. Punishment of death shall, in all cases, be inflicted by intravenous injection of a substance or substances in a lethal quantity sufficient to cause death and until such person sentenced to death is dead, and such execution procedure shall be determined and supervised by the Commissioner of the Department of Correction. The administration of the required lethal substance or substances required by this section shall not be construed to be the practice of medicine and any pharmacist or pharmaceutical supplier is authorized to dispense drugs to the Commissioner or the Commissioner's designee, without prescription, for carrying out the provisions of this section, notwithstanding any other provision of law. Such sentence may not be carried out until final review thereof is had by the Delaware Supreme Court as provided for in subsection (g) of this section. The Court or the Governor may suspend the execution of the sentence until a later date to be specified, solely to permit completion of the process of judicial review of the conviction. If the execution of the sentence of death as provided above is held unconstitutional by a court of competent jurisdiction, then punishment of death shall, in all cases, be inflicted by hanging by the neck.
