Opinion
The defendant, Tarrance Lawrence, appeals, following our grant of certification,
1
from the judgment of the Appellate Court affirming the judgment of the trial court dismissing his motion to correct an illegal sentence, filed pursuant to Practice Book § 43-22,
2
based on the Appellate Court’s determination that the trial court lacked jurisdiction to consider the motion.
State
v.
Lawrence,
The Appellate Court opinion sets forth the following undisputed facts. “The defendant was charged with one count each of murder in violation of General Statutes § 53a-54a (a), carrying a pistol without a permit in violation of General Statutes [Rev. to 1995] § 29-35 and tampering with evidence in violation of General Statutes § 53a-155 (a) (1). The murder charge alleged that the defendant caused the death of a person by use of a firearm. At trial, the defendant presented a defense of extreme emotional disturbance with respect to the murder charge. The court instructed the jury regarding that defense with the following instruction as the defendant had requested: ‘If you unanimously find that the state has proven each of said elements of the crime of murder beyond a reasonable doubt, and if you also unanimously find that the defendant has proven by the preponderance of the evidence each of the elements of the affirmative defense of extreme emotional disturbance, you shall find the defendant guilty of manslaughter in the first degree with a firearm by reason of extreme emotional disturbance and not guilty of murder.’ The jury subsequently found the defendant guilty of manslaughter in the first degree with a firearm in violation of General Statutes § 53a-55a (a) as well as guilty on the other two counts with which he had been charged. The court rendered judgment in accordance with the verdict and sentenced the defendant to thirty-five years on the count of manslaughter in the first degree with a firearm,
*151
two years on the count of carrying a pistol without a permit and three years on the count of tampering with evidence. All sentences were to run concurrently, resulting in a total effective sentence of thirty-five years incarceration. The defendant appealed from his conviction on grounds unrelated to his present claim,
3
and [the Appellate Court] affirmed the judgment.
State
v.
Lawrence,
“The defendant subsequently filed in the trial court a motion to correct an illegal sentence pursuant to Practice Book § 43-22, in which he claimed that his conviction for manslaughter in the first degree with a firearm was improper; he asserted that because the jury had acquitted him of murder on the basis of the affirmative defense of extreme emotional disturbance, the proper conviction should have been of manslaughter in the first degree in violation of General Statutes § 53a-55 (a) (2). The maximum sentence for manslaughter in the first degree is twenty year’s incarceration; see General Statutes § 53a-35a (5); and, therefore, the defendant, in his motion, requested that the court refer the matter to the sentencing judge. The court, after considering the defendant’s claims and the relief requested, dismissed the defendant’s motion for lack of jurisdiction.”
State
v.
Lawrence,
supra,
In his appeal to the Appellate Court from the judgment of dismissal, the defendant claimed that he improperly had been convicted of manslaughter in the first degree with a firearm, and that, had he properly been convicted of manslaughter in the first degree, his *152 sentence of imprisonment could not have exceeded twenty years. According to the defendant, because he was sentenced to thirty-five years imprisonment, his sentence exceeded the statutory maximum permitted under the sentencing statute and he properly invoked the jurisdiction of the court, pursuant to § 43-22; see footnote 2 of this opinion; to correct that illegal sentence. Thus, the defendant’s claim in essence challenged the propriety of the underlying conviction.
The question the Appellate Court resolved, therefore, was whether “§ 43-22 is an appropriate procedural vehicle by which to challenge an allegedly improper conviction or whether the finality of the defendant’s conviction, subject to any collateral challenges the defendant may raise via a petition for a writ of habeas corpus, has left the court without jurisdiction to entertain his claim.”
State
v.
Lawrence,
supra,
The Appellate Court determined that the trial court properly had concluded that it did not have jurisdiction pursuant to § 43-22 and, accordingly, affirmed the trial court’s judgment dismissing the defendant’s motion to correct an illegal sentence. 4 Id., 776. This certified appeal followed.
The defendant claims before this court that, because his conviction is illegal, his sentence is necessarily ille *153 gal and, therefore, his claim falls within the purview of § 43-22. The state responds that, because the defendant is challenging what transpired at trial, his claim does not fall within § 43-22. We agree with the state.
We again rely on the Appellate Court’s opinion for its discussion of the well established principles of jurisdiction guiding our resolution of this issue. “Jurisdiction involves the power in a court to hear and determine the cause of action presented to it and its source is the constitutional and statutory provisions by which it is created.
Connecticut State Employees Assn., Inc.
v.
Connecticut Personnel Policy Board,
“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. . . . This 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. . . . Id., 431-32. There are a limited number of circumstances in which
*154
the legislature has conferred on the trial courts continuing jurisdiction to act on their judgments after the commencement of sentence .... See, e.g., General Statutes §§ 53a-29 through 53a-34 (permitting trial court to modify terms of probation after sentence is imposed); General Statutes § 52-270 (granting jurisdiction to trial court to hear petition for a new trial after execution of original sentence has commenced); General Statutes § 53a-39 (allowing trial court to modify sentences of less than three years provided hearing is held and good cause shown). . . .
State
v.
Boulier,
The defendant does not dispute that the jurisdiction of the sentencing court terminates once a defendant’s sentence has begun and that a court may not take action affecting a defendant’s sentence unless it expressly has been authorized to act. See
State
v.
Reid,
“Practice Book rules do not ordinarily define subject matter jurisdiction. General Statutes § 51-14 (a) authorizes the judges of the Superior Court to promulgate rules regulating pleading, practice and procedure in judicial proceedings .... Such rules shall not abridge, enlarge or modify any substantive right nor the jurisdiction of any of the courts.” (Internal quotation marks omitted.)
State
v.
Carey,
supra,
Accordingly, we examine the categories previously recognized under the common law, beginning with
State
*156
v. McNellis,
Although our courts previously have considered on several occasions the merits of a decision on a motion to correct an illegal sentence, the specific issue of whether a particular claim fell within the purview of an illegal sentence, and, accordingly, whether the trial court had jurisdiction to rule on a motion to correct an illegal sentence, has arisen in only a few cases. In
State
v.
Cator,
supra,
In
State
v.
Mollo,
Reading these cases together, it is clear that a challenge to the legality of a sentence focuses not on what transpired during the trial or on the underlying conviction. In order for the court to have jurisdiction over a motion to correct an illegal sentence after the sentence has been executed, the sentencing proceeding, and not the trial leading to the conviction, must be the subject of the attack. In the present case, the defendant’s claim,
*159
by its very nature, presupposes an invalid conviction. The defendant does not claim, nor could he, that the sentence he received exceeded the maximum statutory limits prescribed for the crime for which he was convicted; rather, he claims that he should have been convicted of a crime that has a lesser maximum statutory limit. He also does not claim that he was denied due process at his sentencing hearing
7
or that his sentence is ambiguous or internally contradictory. See
Cobham
v.
Commissioner of Correction,
supra,
Accordingly, we conclude that the Appellate Court properly decided that the trial court’s determinations that the defendant’s sentence was not subject to review pursuant to a § 43-22 motion to correct an illegal sentence and that it lacked the jurisdiction to review the defendant’s attack on the underlying conviction were correct.
The judgment of the Appellate Court is affirmed.
In this opinion the other justices concurred.
Notes
We granted the defendant’s petition for certification to appeal from the judgment of the Appellate Court, limited to the following issue: “Did the Appellate Court properly conclude that the trial court lacked subject matter jurisdiction to consider the defendant’s motion to correct an illegal sentence?”
State
v.
Lawrence,
Practice Book § 43-22 provides: “The judicial authority may at any time correct an illegal sentence or other illegal disposition, or it may correct a sentence imposed in an illegal manner or any other disposition made in an illegal manner.”
Although we conclude that § 43-22 was not the proper procedural vehicle for the defendant to assert a claim that he should have been convicted of manslaughter in the first degree, rather than manslaughter in the first degree with a firearm, we note that a direct appeal from the judgment of conviction generally would be the proper vehicle for asserting such claims.
Initially, the defendant’s appeal was heard by a three judge panel of the Appellate Court, which, in a split decision, reversed the trial court’s judgment of dismissal, concluding that the trial court had jurisdiction to consider the defendant’s claim, but that, as a matter of law, the sentence was not illegal.
State
v.
Lawrence,
State
v.
McNellis,
supra,
The court in
Cator
did not, however, reach the merits of the defendant’s double jeopardy claim because, as a consequence of the trial court’s action merging the convictions for murder and felony murder, the defendant’s claim had become moot. See
State
v.
Cator,
supra,
See footnote 5 of this opinion.
