§ 9715.  Life imprisonment for homicide. (a)  Mandatory life imprisonment.-- Notwithstanding the provisions of section 9712 (relating to sentences for offenses committed with firearms), 9713 (relating to sentences for offenses committed on public transportation) or 9714 (relating to sentences for second and subsequent offenses), any person convicted of murder of the third degree in this Commonwealth who has previously been convicted at any time of murder or voluntary manslaughter in this Commonwealth or of the same or substantially equivalent crime in any other jurisdiction shall be sentenced to life imprisonment, notwithstanding any other provision of this title or other statute to the contrary. (b)  Proof at sentencing.-- Provisions of this section shall not be an element of the crime and notice thereof to the defendant shall not be required prior to conviction, but reasonable notice of the Commonwealth's intention to proceed under this section shall be provided after conviction and before sentencing. The applicability of this section shall be determined at sentencing. The sentencing court, prior to imposing sentence on an offender under subsection (a), shall have a complete record of the previous convictions of the offender, copies of which shall be furnished to the offender. If the offender or the attorney for the Commonwealth contests the accuracy of the record, the court shall schedule a hearing and direct the offender and the attorney for the Commonwealth to submit evidence regarding the previous convictions of the offender. The court shall then determine, by a preponderance of the evidence, the previous convictions of the offender and, if this section is applicable, shall impose sentence in accordance with this section. Should a previous conviction be vacated and an acquittal or final discharge entered subsequent to imposition of sentence under this section, the offender shall have the right to petition the sentencing court for reconsideration of sentence if this section would not have been applicable except for the conviction which was vacated. (c)  Authority of court in sentencing.-- There shall be no authority in any court to impose on an offender to which this section is applicable any lesser sentence than provided for in subsection (a) or to place such offender on probation or to suspend sentence. Nothing in this section shall prevent the sentencing court from imposing a sentence greater than that provided in this section. Sentencing guidelines promulgated by the Pennsylvania Commission on Sentencing shall not supersede the mandatory sentences provided in this section. (d)  Appeal by Commonwealth.-- If a sentencing court refuses to apply this section where applicable, the Commonwealth shall have the right to appellate review of the action of the sentencing court. The appellate court shall vacate the sentence and remand the case to the sentencing court for imposition of a sentence in accordance with this section if it finds that the sentence was imposed in violation of this section.
