Section 650 - Warrant for execution of death sentence1. When a person is sentenced to the punishment of death, the justice or judge who presided at the sentencing proceeding, or if that justice or judge is unavailable for any reason, then any justice of the supreme court of the department in which the defendant was sentenced, must, within seven days, make out, sign and deliver to the sheriff of the county, a warrant directed to the commissioner or to the superintendent of an institution in the department designated by the commissioner. Such warrant shall state the conviction and sentence, appoint a week on which the sentence shall be executed, and command the commissioner to execute the sentence within that week. In counties within the city of New York, or in the county of Westchester, such warrant shall be made out as aforesaid, signed and delivered to the commissioner of correction of such city or county.2. If the execution of the sentence shall be delayed while the conviction or sentence is being appealed, a justice or judge authorized to act pursuant to subdivision one of this section, at the conclusion of the state appellate process, if the conviction or sentence is not set aside, must, within seven days, make out, sign and deliver another warrant as provided in subdivision one of this section. If the execution of the sentence on the date appointed is delayed by any other cause, the justice or judge shall, as soon as such cause ceases to exist, make out, sign and deliver another warrant.
