We granted a petition for certification in this case to consider the constitutional validity of General Statutes § 54-56C11 as it has been applied to the defendant, Dwayne Murray. The statute establishes the procedures that govern adjudication of a defendant’s competency to be tried, convicted or sentenced in criminal proceedings, once a defendant’s competency has been called into question.
The procedural history of this case establishes that a jury found the defendant guilty of having committed the crimes of attempted murder in violation of General Statutes §§ 53a-49 (a) (2) and 53a-54a, assault in the first degree in violation of General Statutes § 53a-59 (a) (1), and burglary in the first degree in vio*526lation of General Statutes § 53a-101 (a) (2). 2 The trial court rendered a judgment of conviction, from which the defendant appealed to the Appellate Court. The Appellate Court affirmed the judgment of the trial court. State v. Murray, 28 Conn. App. 548, 557, 611 A.2d 916 (1992). We then granted the defendant’s petition for certification to appeal. State v. Murray, 224 Conn. 907, 615 A.2d 1049 (1992).
The issue that we certified is: “Did the Appellate Court correctly hold that the record was inadequate to rule whether General Statutes § 54-56d was unconstitutionally applied to the defendant?” Recognizing that no issue concerning the constitutionality of the statute had been raised in the trial court, the Appellate Court refused to address the merits of the defendant’s belated due process challenge in light of the defendant’s failure to comply with the requirements of State v. Evans, 165 Conn. 61, 70, 327 A.2d 576 *527(1973), as refined by State v. Golding, 213 Conn. 233, 239-40, 567 A.2d 823 (1989). The Appellate Court con-eluded that the record was inadequate for Evans-Golding review because “[t]he trial court never ruled on the defendant’s motion for a competency hearing and, therefore, § 54-56d was never applied to the defendant. Without a hearing on the motion, and without findings or rulings of the trial court, there is no record to review.” State v. Murray, supra, 28 Conn. App. 552.
In this court, the defendant argues that the trial court impliedly denied his motion for a competency hearing, while the state maintains that the defendant impliedly waived his motion by failing to renew it after the trial court had apparently resolved the immediate difficulties that led to the defendant’s motion. The most that can be said for the defendant’s contention is that the trial court proceedings, fully described in the opinion of the Appellate Court; State v. Murray, supra, 28 Conn. App. 551-52; are arguably ambiguous about the trial court’s response to the defendant’s motion. Such an ambiguity would support the conclusion of the Appellate Court that the defendant has failed to provide a record that is adequate for appellate review of his belated constitutional challenge to the validity of § 54-56d as applied to him.
Because the application of § 54-56d to the defendant is a prerequisite to his due process challenge to the constitutionality of the statute, and because that issue was fully explored by the Appellate Court, it would serve no useful purpose for us to address the substantive merits of the defendant’s claim. After examining the record on appeal and after considering the briefs and the arguments of the parties, we conclude, therefore, that the appeal in this case should be dismissed on the ground that certification was improvidently granted. *528See Booth v. Flanagan, 220 Conn. 453, 455, 599 A.2d 380 (1991); Lawler v. Lawler, 212 Conn. 117, 119, 561 A.2d 128 (1989).
The appeal is dismissed.
General Statutes § 54-56d provides in relevant part: “competency to STAND TRIAL, (a) COMPETENCY REQUIRED, definition. A defendant shall not be tried, convicted or sentenced while he is not competent. For the purposes of this section, a defendant is not competent if he is unable to understand the proceedings against him or to assist in his own defense.
“(b) presumption of competency. A defendant is presumed to be competent. The burden of proving that the defendant is not competent by clear and convincing evidence and the burden of going forward with the evidence are on the party raising the issue ....
“(c) REQUEST FOR examination. If at any time during a criminal proceeding it appears that the defendant is not competent, counsel for the defendant or for the state, or the court, on its own motion, may request an examination to determine the defendant’s competency.
“(d) examination of defendant, report. If the court finds that the request for an examination is justified and that, in accordance with procedures established by the judges of the superior court, there is probable cause to believe that the defendant has committed the crime for which he is charged, the court shall order an examination of the defendant as to his competency. . . .”
