In 1973, a jury convicted Perez of murder in the first degree, among other offenses. The judge sentenced him to life imprisonment pursuant to G. L. c. 265, § 2. This court affirmed his conviction in Commonwealth v. Perez, 390 Mass. 308 (1983). Thirty years after his conviction, Perez now claims that his sentence was improper because the United States Supreme Court’s decision in Furman v. Georgia, 408 U.S. 238 (1972) — decided the year before Perez was convicted and eleven years before this court reviewed and affirmed his conviction — nullified in its entirety the statute under which he was sentenced.
Perez’s appeal suffers from two fundamental flaws. First, the decision of the single justice, acting as a gatekeeper pursuant to G. L. c. 278, § 33E, is “final and unreviewable.” Napolitano v. Attorney Gen., 432 Mass. 240, 241 (2000), citing Commonwealth v. Ambers, 397 Mass. 705, 710-711 (1986), and Dickerson v. Attorney Gen., 396 Mass. 740, 742 (1986). For this reason alone, his appeal must be dismissed. Second, this court has repeatedly rejected similar challenges to the validity of G. L. c. 265, § 2. See Napolitano v. Attorney Gen., supra at 243 (“no rights of this plaintiff have been infringed whatsoever by the life sentences imposed in the first instance by the trial judge”); Valliere v. Superintendent of Mass. Correctional Insts., 429 Mass. 1024, 1025 (1999) (“By changing the death sentence to life imprisonment, this court did not infringe on any rights belonging to the petitioner. In effect, he ended up with the most lenient sentence he could have possibly received, given the convictions of murder in the first degree”); Commonwealth v. Cassesso, 368 Mass. 124, 125 (1975) (“With the invalidation of the death *1020penalty in discretionary circumstances, such as exist under the language of G. L. c. 265, § 2, the only remaining relevant permissible penalty is imprisonment for life. We arrive at this conclusion as matter of statutory construction. The jury have no remaining sentencing function. The judge must impose the sentence”).
The case was submitted on the papers filed, accompanied by a memorandum of law. Luis Perez, pro se. Loretta M. Lillios, Assistant District Attorney, for the Commonwealth.Appeal dismissed.
