*145The self-represented defendant, Abdul Mukhtaar, appeals from the judgment of the trial court dismissing his motion to correct an illegal sentence filed pursuant to Practice Book § 43-22.1 On appeal, he argues that the court improperly dismissed this motion. We disagree and, accordingly, affirm the judgment of the trial court.
The following facts and procedural history are necessary for the resolution of this appeal. The defendant was convicted of murder in violation of General Statutes § 53a-54a and sentenced to fifty years incarceration. See *146State v. Mukhtaar , 253 Conn. 280, 281-82, 750 A.2d 1059 (2000).2 Our Supreme Court affirmed the judgment of conviction on direct appeal. See id., at 282, 750 A.2d 1059.3 *31The defendant filed the motion to correct an illegal sentence that is the subject of the present appeal on *147January 19, 2018. In this motion, the defendant alleged that his sentence was illegal because (1) Judge Gormley had presided over both the defendant's probable cause hearing4 and the criminal trial, (2) Judge Gormley was biased, (3) Judge Gormley did not order a competency examination pursuant to General Statutes (Rev. to 1997) § 54-56d5 and (4) there were inconsistent statements by witnesses during the criminal investigation and trial.
On February 14, 2018, the court conducted a hearing on the defendant's motion. In addition to the claims set forth in his motion, the defendant also claimed that his sentence was illegal because the Bridgeport Police Department lost and destroyed evidence before the criminal trial and that he was the victim of implicit bias. One week later, the court, Devlin, J. , issued a memorandum of decision dismissing the defendant's motion to correct an illegal sentence. After setting forth the relevant law, the court concluded: "None of the six claims raised by the defendant concerns his sentence or the manner in which it was imposed. To the contrary, his claims regarding judicial bias, lack of competency examination, implicit bias, inconsistent statements, lost evidence and that the same judge presided over the [probable cause hearing] and trial, all concern the underlying conviction and not the defendant's sentence. Accordingly, this court lacks jurisdiction to consider these claims." This appeal followed. Additional facts will be set forth as necessary.
On appeal, the defendant claims that the court improperly concluded that it lacked jurisdiction to consider the issues raised in his motion to correct an illegal sentence. The state counters, inter alia, that all of the *148defendant's issues focus on the events that occurred prior to his sentencing, and therefore the court properly dismissed the motion to correct. We agree with the state.
At the outset, we identify our standard of review. "Our determination of whether a motion to correct falls within the scope of Practice Book § 43-22 is a question of law and, thus, our review is plenary." (Internal quotation marks omitted.) State v. Anderson , 187 Conn. App. 569, 584, 203 A.3d 683 (2019) ; see also State v. Delgado , 323 Conn. 801, 810, 151 A.3d 345 (2016) ; State v. Robles , 169 Conn. App. 127, 131, 150 A.3d 687 (2016), cert. denied, 324 Conn. 906, 152 A.3d 544 (2017).
Next, we set forth the legal principles pertaining to the trial court's jurisdiction following a judgment of conviction. "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.... It is well established that under the common law a trial court has the discretionary power to modify or vacate a criminal judgment before the sentence has been executed....
*32This is so because the court loses jurisdiction over the case when the defendant is committed to the custody of the commissioner of correction and begins serving the sentence.... Because it is well established that the jurisdiction of the trial court terminates once a defendant has been sentenced, a trial court may no longer take any action affecting a defendant's sentence unless it expressly has been authorized to act.... [Practice Book] § 43-22 embodies a common-law exception that permits the trial court to correct an illegal sentence or other illegal disposition.... Thus, if the defendant cannot demonstrate that his motion to correct falls within the purview of § 43-22, the court lacks jurisdiction to entertain it.... [I]n order for the court to have jurisdiction over a motion to correct an illegal *149sentence after the sentence has been executed, the sentencing proceeding [itself] ... must be the subject of the attack ....
"[A]n illegal sentence is essentially one [that] either exceeds the relevant statutory maximum limits, violates a defendant's right against double jeopardy, is ambiguous, or is internally contradictory. By contrast ... [s]entences imposed in an illegal manner have been defined as being within the relevant statutory limits but ... imposed in a way [that] violates [a] defendant's right ... to be addressed personally at sentencing and to speak in mitigation of punishment ... or his right to be sentenced by a judge relying on accurate information or considerations solely in the record, or his right that the government keep its plea agreement promises .... These definitions are not exhaustive, however, and the parameters of an invalid sentence will evolve ... as additional rights and procedures affecting sentencing are subsequently recognized under state and federal law." (Emphasis added; internal quotation marks omitted.) State v. Anderson , supra, 187 Conn. App. at 583-84, 203 A.3d 683 ; see also State v. Evans , 329 Conn. 770, 778-80, 189 A.3d 1184 (2018), cert. denied, --- U.S. ----, 139 S.Ct. 1304, --- L.Ed.2d ---- (2019) ; State v. Parker , 295 Conn. 825, 833-39, 992 A.2d 1103 (2010) ; see generally State v. Lawrence , 281 Conn. 147, 153-59, 913 A.2d 428 (2007) ; State v. McNellis , 15 Conn. App. 416, 443-44, 546 A.2d 292, cert. denied, 209 Conn. 809, 548 A.2d 441 (1988).
Next, we turn to the specific allegations contained in the defendant's motion to correct an illegal sentence. He claims that his sentence was illegal because Judge Gormley had presided over the probable cause hearing and the criminal trial, two of the state's witnesses had provided inconsistent statements during the criminal investigation and trial proceedings, Judge Gormley did *150not order a competency hearing on behalf of the defendant either "pre or post trial,"6 and the Bridgeport Police Department had lost and destroyed evidence prior to the criminal trial. These contentions do not attack the sentencing proceeding but, rather, concern the pretrial proceedings and the criminal trial. "[I]n order for the court to have jurisdiction *33over a motion to correct an illegal sentence after the sentence has been executed, the sentencing proceeding, and not the [proceedings] leading to the conviction, must be the subject of the attack." (Internal quotation marks omitted.) State v. Cruz , 155 Conn. App. 644, 651, 110 A.3d 527 (2015) ; see also State v. St. Louis , 146 Conn. App. 461, 466-67, 76 A.3d 753, cert. denied, 310 Conn. 961, 82 A.3d 628 (2013).
The remaining two allegations of the defendant, that there was an implicit bias against him because he is African-American and the victim was Caucasian, and that Judge Gormley was biased as evidenced by his failure to order a competency hearing, likewise are not limited to the events of the sentencing proceeding. Additionally, they do not fit within the definitions of either an illegal sentence or a sentence imposed in an illegal manner. See State v. Anderson , supra, 187 Conn. App. at 583-84, 203 A.3d 683 ; see also State v. Evans , supra, 329 Conn. at 779, 189 A.3d 1184. We iterate that "[t]he claims that may be raised in a motion to correct an illegal sentence are strictly limited *151to improprieties that may have occurred at the sentencing stage of the proceeding.... Thus ... for the trial court to have jurisdiction to consider the defendant's claim of an illegal sentence, the claim must fall into one of [several specific] categories of claims that, under the common law, the court has jurisdiction to review." (Internal quotation marks omitted.) State v. Walker , 187 Conn. App. 776, 784, 204 A.3d 38 (2019). For these reasons, we conclude that the trial court properly determined that it lacked jurisdiction to consider the defendant's motion to correct an illegal sentence.
The judgment is affirmed.
