Approval of the Board of Pardons to apply this provision was required where the petitioner would be released from custodial confinement under this provision at an earlier date than he would have been under the prior law in effect at the time of his sentencing. Actions of the Board of Pardons in allowing or denying the benefits of this provision are an exercise of its power to grant clemency, and not subject to ordinary due process requirements. Whited v. Bolin, 210 Neb. 32, 312 N.W.2d 691 (1981).

This section means prisoners need the approval of the Board of Pardons before the provisions of Laws 1975, L.B. 567, apply retroactively. Johnson & Cunningham v. Exon, 199 Neb. 154, 256 N.W.2d 869 (1977).
