The penalty reduction provisions of the Drug Law Reform Act (L 2004, ch 738) do not apply to defendants sentenced prior to its enactment ( People v. Walker, 81 NY2d 661, 666-667), and we reject defendant's arguments to the contrary. Since defendant received the minimum sentence permitted by law, this Court has no authority to reduce it as a matter of discretion in the interest of justice (CPL 470.20).
