¶1John Baldwin appeals from a judgment of a single justice of this court denying his petition for relief pursuant to G. L. c. 211, § 3. We affirm.
¶2Baldwin is the subject of a pending civil commitment proceeding in the Superior Court, pursuant to G. L. c. 123A, having pleaded guilty to various *1024sex offenses and having completed his criminal sentences. In March, 2006, he filed, in connection with his criminal case, a pro se motion “To Enforce Plea Agreement Entered Into By The Commonwealth,” claiming that the Commonwealth’s petition for civil commitment violated Baldwin’s plea agreement. A judge in the Superior Court denied the motion, concluding that the matter was controlled by Commonwealth v. Cruz, 62 Mass. App. Ct. 610 (2004). Baldwin filed a timely notice of appeal and a request for the appointment of counsel. In May, 2006, counsel was appointed. Counsel did not pursue an appeal because he concluded that it would lack merit in light of the Cruz decision. Counsel did, however, file a motion for a new trial on Baldwin’s behalf, raising different claims from those raised by Baldwin in his pro se motion. The motion for a new trial was denied, as was a motion for reconsideration. The Appeals Court affirmed those rulings. See Commonwealth v. Baldwin, 73 Mass. App. Ct. 1122 (2009). In connection with that appeal, Baldwin attempted to file a pro se brief addressing the denial of his motion to enforce the plea agreement, but his brief was not accepted.
¶3Baldwin has filed a memorandum and appendix pursuant to S.J.C. Rule 2:21, as amended, 434 Mass. 1301 (2001). Although the rule does not technically apply because Baldwin is not seeking review of an “interlocutory ruling in the trial court,” S.J.C. Rule 2:21 (1), the record before us shows that he had an adequate alternative to relief under G. L. c. 211, § 3. Concerning his attempt to appeal from the denial of his motion to enforce the plea agreement, it appears from the Superior Court docket that a record was never assembled and transmitted to the Appeals Court, and without the record having been assembled the case could not have been docketed in the Appeals Court. See Mass. R. A. P. 9, as amended, 437 Mass. 1602 (2002).
¶4 Judgment affirmed.
¶5In that brief, Baldwin argued, among other things, that Commonwealth v. Cruz, 62 Mass. App. Ct. 610 (2004), had been wrongly decided.
¶6Baldwin claims that his counsel sent a letter to the Superior Court clerk, in September, 2008, explaining that Baldwin wished to pursue such an appeal pro se, and requesting that the court assemble the record for that appeal. There is no indication on the Superior Court docket, however, that Baldwin moved in the Superior Court for an order compelling the clerk to do so. See Keane v. Commonwealth, 439 Mass. 1002, 1002 (2003), and cases cited.
