*398 Opinion
The dispositive issue in this appeal is whether a trial court has jurisdiction to consider an objection to the entry of a nolle prosequi filed seven weeks after the nolle was entered in the defendant’s presence. The defendant, Michael Daly, appeals from the judgment of the trial court denying his objection to the entry of a nolle. We conclude that the court lacked jurisdiction to consider the objection. Accordingly, we reverse the judgment and remand the case to the trial court with instruction to dismiss the defendant’s objection.
The record reveals the following relevant facts and procedural history. The defendant was charged with five crimes in three separate files. In CR-06-0205321, the defendant was charged with interfering with an officer in violation of General Statutes § 53a-167a. In CR-06-0205320, the defendant was charged with possession of narcotics in violation of General Statutes § 21a-279 (a) and use of drug paraphernalia in violation of General Statutes § 21a-267 (a). In CR-06-0205317, the defendant was charged with robbery in the third degree in violation of General Statutes § 53a-136 and larceny in the third degree in violation of General Statutes § 53a-124. On February 21, 2007, the defendant pleaded guilty under the Alford doctrine1 to the charges of robbery in the third degree, larceny in the third degree and possession of narcotics. Following the imposition of the sentence, the court stated: “Costs and fees will be imposed. Nolle noted open counts.” The defendant’s attorney clarified with the court that costs would be waived. The court clerk then asked: “And a nolle on the open file, Your Honor?” The court responded: “Open file.” A nolle was entered for the charges of interfering with an officer and use of drug paraphernalia.
*399On February 28, 2007, the defendant, representing himself, filed a motion for transcript, requesting a copy of the transcript of the February 21, 2007 proceeding. In this motion, he stated that he was not present when the nolle was entered. On March 5, 2007, the court denied the defendant’s motion, noting that “[the defendant] was present during the entering of the nolle.” On March 19, 2007, the defendant filed a motion for reconsideration of the court’s denial of his motion for transcript, which the court denied on March 20, 2007. On April 11, 2007, the defendant filed an objection to the entry of the nolle, again stating that he was not present when the nolle was entered. The court denied the objection on April 12, 2007. In a subsequent memorandum of decision, dated February 8, 2008, the court explained that it denied the defendant’s objection to the entry of a nolle on the basis of its finding that the defendant was present in court during the entering of the nolle. On August 7, 2007, the defendant filed this appeal from the denial of his objection to the entry of a nolle.
On appeal, the defendant claims that the court improperly denied his objection to the entry of the nolle because the state did not comply with General Statutes § 54-56b and Practice Book §§ 39-29 and 39-30. Specifically, the defendant argues that because the prosecutor did not initiate the nolle or comply with the requirements of the § 54-56b and Practice Book §§ 39-29 and 39-30, the court abused its discretion when it noted the nolle on its own volition. Because the defendant did not object timely to the court’s decision to allow the nolle, but instead appeals from its denial of his later objection to that disposition, we decline to consider the merits of this claim. Rather, we conclude that the court did not have jurisdiction to consider the defendant’s objection.2
*400Preliminarily, we note that a fact critical to our jurisdictional analysis was not properly challenged in the defendant’s appeal. The defendant asserts in his brief that he was not aware that the nolle was entered. Specifically, he argues that it is “pretty certain” that either he had left the courtroom or was in the process of leaving the courtroom when the court noted the nolle or that he misunderstood what was happening. The defendant reasons that we can infer that he was unaware the nolle was entered on the basis of his subsequent motions and his argument before this court. Such speculation is not sufficient to challenge the trial court’s factual finding that “[the defendant] was present during the entering of the nolle”; see State v. Brown, 256 Conn. 291, 311-12, 772 A.2d 1107 (nonreviewability of claim when analysis and authority lacking), cert. denied, 534 U.S. 1068, 122 S. Ct. 670, 151 L. Ed. 2d 584 (2001); and we do not have grounds to conclude otherwise.* *3 Moreover, it is well established that as an appellate tribunal, we do not find facts. Gibson v. Commissioner of Correction, 98 Conn. App. 311, 318 n.5, 908 A.2d 1110 (2006), cert. denied, 281 Conn. 908, 916 A.2d 49 (2007); *401 State v. Zollo, 36 Conn. App. 718, 726, 654 A.2d 359, cert. denied, 234 Conn. 906, 660 A.2d 859 (1995).
Declining to disturb the court’s determination that the defendant was present during the entry of the nolle, we turn now to a discussion of subject matter jurisdiction. The state argues that the court did not have jurisdiction over the defendant’s objection to the entry of the nolle and that “a want of jurisdiction in that court would eliminate our authority to consider the issues raised on this appeal.” Hartford National Bank & Trust Co. v. Tucker, 178 Conn. 472, 477, 423 A.2d 141 (1979), cert. denied, 445 U.S. 904, 100 S. Ct. 1079, 63 L. Ed. 2d 319 (1980). “[A] subject matter jurisdictional defect may not be waived ... [or jurisdiction] conferred by the parties, explicitly or implicitly. . . . [T]he question of subject matter jurisdiction is a question of law . . . and, once raised, either by a party or by the court itself, the question must be answered before the court may decide the case.” (Internal quotation marks omitted.) Commissioner of Transportation v. Rocky Mountain, LLC, 277 Conn. 696, 703, 894 A.2d 259 (2006). Our review of this question of law is plenary. State v. Fowlkes, 283 Conn. 735, 738, 930 A.2d 644 (2007).
Subject matter jurisdiction involves a court’s authority to adjudicate the type of controversy presented in the action before it. State v. Carey, 222 Conn. 299, 304, 610 A.2d 1147 (1992), on appeal after remand, 228 Conn. 487, 636 A.2d 840 (1994). “The Superior Court is a constitutional court of general jurisdiction. ... In the absence of statutory or constitutional provisions, the limits of its jurisdiction are delineated by the common law.” (Internal quotation marks omitted.) State v. Lawrence, 281 Conn. 147, 153, 913 A.2d 428 (2007); see Conn. Const., art. V, § 1. The Superior Court’s authority over criminal cases is established by the “proper presentment of the information . . . which is essential to *402initiate a criminal proceeding.” Reed v. Reincke, 155 Conn. 591, 598, 236 A.2d 909 (1967).
We apply the previously mentioned principles of subject matter jurisdiction as we determine the status of a criminal case following the entry of a nolle. The effect of a nolle is to terminate the particular prosecution of the defendant without an acquittal and without placing him in jeopardy. State v. Herring, 209 Conn. 52, 57, 547 A.2d 6 (1988); State v. Lloyd, 185 Conn. 199, 201, 440 A.2d 867 (1981); see Bucolo v. Adkins, 424 U.S. 641, 642, 96 S. Ct. 1086, 47 L. Ed. 2d 301 (1976). “Upon entry of a nolle, the individual concerned is no longer a defendant in a criminal case. He stands accused of no crime and his release is unconditional. . . . After entry of [a] nolle [a] defendant . . . [is] not under arrest, not in custody, and not subject to any criminal prosecution.” (Internal quotation marks omitted.) State v. Gaston, 198 Conn. 435, 441, 503 A.2d 594 (1986). “The nolle, like a nonsuit or a discontinuance in a civil suit, [leaves] the matter just where it stood before the commencement of the prosecution.” State v. Main, 31 Conn. 572, 576 (1863).
Therefore, the nolle places the criminal matter in the same position it held prior to the filing of the information. Indeed, no criminal matter exists until, and if, the prosecution issues a new information against the defendant. As our rules explain, “[t]he entry of a nolle prosequi terminates the prosecution and the defendant shall be released from custody. If subsequently the prosecuting authority decides to proceed against the defendant, a new prosecution must be initiated.” Practice Book § 39-31.4 The defendant is accused of no crime, is released from custody unconditionally and is no longer *403under the authority of the court. It follows that, generally, a court does not have jurisdiction over the case after the entiy of a nolle. See Reed v. Reincke, supra, 155 Conn. 598; see also General Statutes § 54-56 (“[a]ll courts having jurisdiction of criminal cases shall at all times have jurisdiction and control over informations and criminal cases pending therein . . . .” [emphasis added]).
Our Supreme Court, however, has recognized limited instances in which a trial court may retain jurisdiction following the entry of a nolle. State v. Lloyd, supra, 185 Conn. 205. “We have held that even after the entry of a nolle the court retains limited jurisdiction over the case to hear such matters as the defendant’s motion to dismiss based on the alleged denial of the right to a speedy trial.” (Emphasis in original.) State v. Gaston, supra, 198 Conn. 443. In Lloyd, the state entered a nolle over the defendant’s objection and over his renewed motion to dismiss on speedy trial grounds.5 State v. Lloyd, supra, 200-201. Our Supreme Court held that the trial court had jurisdiction to consider the defendant’s motion for a speedy trial even after the court’s acceptance of the nolle. Id., 206. The court concluded that “[t]he defendant’s timely, and timely renewed, motions to dismiss required resolution before the pending proceedings could be fully terminated.” Id.
The defendant’s objection in the present case, by contrast, was not timely. Where our Supreme Court has ruled on the entry of a nolle over the defendant’s objection, the objection has been timely. State v. Herring, supra, 209 Conn. 54 (state indicated it intended to enter nolle and defendant objected immediately *404thereafter); see also State v. Gaston, supra, 198 Conn. 443 (noting that court’s holding in Lloyd “assumed a fortiori that [the motion to dismiss on speedy trial grounds] was properly raised before the entry of a nolle” [emphasis in original]). Practice Book § 39-30 specifically allows for a timely objection. It provides: “Where a prosecution is initiated by complaint or information, the defendant may object to the entering of a nolle prosequi at the time it is offered by the prosecuting authority and may demand either a trial or a dismissal, except when a nolle is entered upon a representation to the judicial authority by the prosecuting authority that a material witness has died, disappeared or become disabled or that material evidence has disappeared or has been destroyed and that a further investigation is therefore necessary.” (Emphasis added.) Practice Book § 39-30. The defendant here did not make his objection to the entry of the nolle until approximately seven weeks after the nolle had been entered. Unlike the situations in Herring and Lloyd, the defendant did not voice his objection before or immediately after the nolle was entered. See State v. Herring, supra, 54; State v. Lloyd, supra, 185 Conn. 207 (“[t]he purpose of providing judicial oversight over the entry of a nolle prosequi to which the defendant has timely objected is to protect the defendant from the repeated initiation and termination of charges that . . . leave him in legal limbo” [emphasis added]). Instead, as noted previously, the defendant here waited seven weeks to file his objection. Thus, the defendant’s objection was not timely and fell outside of the limited jurisdiction retained by the court following the entry of a nolle. Accordingly, we conclude that the limited jurisdiction retained by the court after the entry of a nolle does not extend to the defendant’s untimely objection.
The form of the judgment is improper. The judgment denying the defendant’s objection to the entry of the *405nolle prosequi is reversed and the case is remanded with direction to dismiss the defendant’s objection.
In this opinion the other judges concurred.
