PALMER, J.
  

   The plaintiff, Brenda Snell, brought this negligence action against the defendants, Johnley Sainval, a taxicab driver, his employer, Norwalk Yellow Cab, Inc. (Yellow Cab), and Vito Bochicchio, Jr., the sole shareholder of Yellow Cab, seeking damages for serious injuries she sustained when she was struck by a taxicab that had been stolen from Sainval by two teenagers after Sainval left the vehicle unattended with the key in the ignition in a Norwalk neighborhood known to have a higher than average crime rate. A jury trial ensued at which the defendants claimed, inter alia, that the conduct of the two thieves was a superseding cause that relieved Sainval of any liability to the plaintiff for his alleged negligence. At the conclusion of the trial, the jury, in response to interrogatories submitted to it by the trial court, found that Sainval was negligent in leaving the taxicab unattended with the key in the ignition; that, in light of the surrounding neighborhood, it was reasonably foreseeable that the vehicle would be stolen and operated in an unsafe manner; and that Sainval's negligence was a proximate cause of some or all of the plaintiff's injuries. The jury also found, nevertheless, that the defendants were not liable for the plaintiff's injuries because the accident that occurred was not within the scope of the risk created by Sainval's negligence.
  

   The plaintiff thereafter filed a motion to set aside the verdict and for a new trial claiming, inter alia, that the jury's finding that Sainval's negligence constituted a proximate cause of the accident was legally inconsistent with its finding that the accident was outside the scope of the risk created by Sainval's negligence. The court denied the motion and rendered judgment in accordance with the jury's verdict. The plaintiff then appealed to the Appellate Court, claiming that (1) it was improper for the trial court to instruct the jury on the doctrine of superseding cause, (2) even if the
   doctrine were properly submitted to the jury, the court's instructions and interrogatories misled the jury, and (3) the trial court improperly denied the plaintiff's motion to set aside the verdict and for a new trial on the ground that the jury's verdict was irreconcilable with its responses
   to the interrogatories.

   . Although we answer the first question in the affirmative, we answer the second in the negative and, accordingly, reverse the judgment of the Appellate Court.
  

   The opinion of the Appellate Court sets forth the following relevant facts, which the jury reasonably could have found, and procedural history. "On December 3, 2009, Sainval, who was employed by Yellow Cab as a taxicab driver, was operating a taxicab owned by Yellow Cab in Norwalk. In the early evening, he drove the taxicab to Monterey Village, a housing complex located in an area of the city with significant criminal activity. Sainval parked the taxicab and went inside one of the apartments, leaving the taxicab unlocked and unattended with the keys in the ignition.
  

   "Two teenagers, Shaquille Johnson and Deondre Bowden, who that afternoon had been consuming alcohol and smoking marijuana, noticed the parked taxicab. Although they initially intended to steal anything of
   value that they could find inside the unlocked taxicab, once they observed the keys in the ignition, the two teens decided to steal the taxicab and to go on a 'joy-ride.' They drove the taxicab from Norwalk to Stamford, making one brief stop in between, with each of the teens taking a turn driving the vehicle.
  

   "When they reached Stamford, they [encountered] traffic. At that time, Bowden was driving the taxicab. He 'kind of nodded off' and rear-ended the vehicle in front of him. Bowden, who was both 'tipsy' and 'high,' then attempted to flee the scene. In order to maneuver the taxicab around the vehicle he had struck, Bowden drove the taxicab up over the curb of the road and onto the adjoining sidewalk. In doing so, Bowden first hit a fire hydrant before striking the plaintiff with the taxicab.
  

   "The plaintiff sustained severe physical injuries, particularly to her midsection, requiring millions of dollars in medical expenditures as of the time of trial, with additional treatments and surgeries expected. After hitting the plaintiff, Bowden never attempted to stop the vehicle; he and Johnson exited the stolen taxicab while it was still moving and fled the scene on foot, returning home by train. The police later identified the teens as the individuals involved in the hit and run of the plaintiff and arrested them.

   "The plaintiff initially commenced this action solely against Sainval and Yellow Cab.

   Johnson and Bowden
   were not
   named by the plaintiff as defendants in the civil action. Although the defendants filed an apportionment complaint against the two teens, the court later granted the plaintiff's motion to strike the apportionment complaint, agreeing with the plaintiff that apportionment was unavailable in the present case because the misconduct of the teenagers was not pleaded as mere negligence but as reckless or intentional conduct. See General Statutes § 52-572h (
   
    o
   
   ) ('there shall be no apportionment of liability or damages between parties liable for negligence and parties liable on any basis other than negligence including, but not limited to, intentional, wanton or reckless misconduct');

   "The operative second amended complaint contains two counts relevant to the issues on appeal.
   
    3
   
   Count one sounds in negligence against Sainval. According to the plaintiff, Sainval acted negligently by leaving his taxicab in an unguarded public parking lot in a high crime area with the keys in the ignition, which created the reasonably foreseeable risk that the taxicab would be stolen and that a thief would drive the taxicab in an
   unsafe manner and cause injury to a person or to property. Count two alleges that Yellow Cab was vicariously liable for Sainval's negligence on a theory of respondeat superior. Prior to trial, Yellow Cab conceded that it would be liable to the same extent that Sainval was found liable on count one.
  

   "In their amended answer, the defendants, by way of a special defense, raised the doctrine of superseding cause. The defendants pleaded that, '[i]f the plaintiff sustained the injuries and losses as alleged in her complaint, said injuries and losses were the result of the intentional, criminal, reckless and/or negligent conduct of a third party, which intervened to break the chain of causation between [Sainval's] alleged negligence and/or carelessness and the plaintiff's alleged injuries and losses.'

   "[T]he court initially indicated to the parties that it was not inclined to give a superseding cause instruction to the jury because, on the basis of its reading of ...

   v.
   
    Quality Steel Products, Inc.
   
   , [
   
    263 Conn. 424
   
   ,
   
    820 A.2d 258
   
   (2003) ], superseding cause was no longer part of our tort jurisprudence except in limited circumstances,
   specifically, cases involving either an intervening intentional tort, act of nature, or criminal event that was unforeseeable to the defendant. The court suggested that the exception was not at issue in the present case because, under the plaintiff's theory of liability, the intervening theft of the car was entirely foreseeable.
  

   "The defendants, however, argued that the court was focusing on the wrong criminal act. They indicated that it was not necessarily the theft of the taxicab in this case that warranted an instruction on superseding cause but the unforeseeability of the thieves' subsequent criminal
   conduct, namely, intentionally driving the taxicab up onto a sidewalk to evade responsibility for a rear-end collision and the ensuing criminal assault on the plaintiff. Furthermore, the defendants noted that part of the court's rationale in
   
    Barry
   
   for abandoning the doctrine of superseding cause in cases alleging that an intervening negligent act or acts contributed to a plaintiff's injuries was that apportionment of liability between tortfeasors was permitted, which would prevent a less culpable defendant from inequitably shouldering full responsibility for injuries that resulted from multiple negligent acts. The defendants contended that, unlike
   
    Barry
   
   , this case involved intervening actions of other tortfeasors that were not merely negligent but reckless and criminal. In such a case, the defendants argued, apportionment of liability is unavailable by statute; see General Statutes § 52-572h (
   
    o
   
   ) ; and, thus, the primary policy rationale underlying the abolishment of the doctrine of superseding cause was absent. The court indicated that it would review the case law and give the issue further consideration in light of these arguments.
  

   "[Subsequently], the court provided counsel with the latest draft of its jury instructions and also with copies of draft interrogatories that the court intended to submit to the jury. The court indicated that the current version of the instructions included a new paragraph that the court had decided to add after further consideration of the case law concerning superseding cause and its discussions with the parties. That paragraph instructed the jury to consider whether the theft of the taxicab and the resulting accident involved intentional acts that were outside the scope of the risk created by Sainval's conduct, and that if the jury found this to be so, then the defendants should not be found responsible for the plaintiff's injuries because the conduct of the two teens would have been the proximate cause of those injuries, thus relieving the defendants of any liability. The court
   also drafted a new, related interrogatory that asked the jury to state whether the 'accident' that occurred was outside the scope of the risk created by Sainval's act of leaving the keys in the ignition of the taxicab. The court directed the jury to return a verdict for the defendants if the answer to that inquiry was yes.
  

   "Following the close of evidence later that day, the court held a charging conference. At the charging conference, the plaintiff stated that it believed the additional paragraph added by the court to its latest draft instructions was unnecessary and confusing and that, in defining and explaining the concept of proximate cause, the court adequately had covered both foreseeability and whether Sainval's conduct was a substantial factor in causing the plaintiff's injuries. The plaintiff also stated that she did not think there was any evidence from which the jury could construe that the teens had intentionally sought to harm her. The court suggested that the additional instruction was necessary to comport with case law, referring in particular to
   
    Sullivan
   
   v.
   
    Metro-North Commuter Railroad Co.
   
   ,
   
    292 Conn. 150
   
   ,
   
    971 A.2d 676
   
   (2009). It indicated its belief that foreseeability for purposes of determining negligence and scope of the risk for purposes of applying superseding cause, although closely related, were slightly different concepts.
   
    4
   
   The court agreed that there was nothing in
   the record to support a finding that the assault on the plaintiff was intentional but noted that the two teens had also engaged in other criminal conduct, including intentionally stealing the taxicab and intentionally fleeing the scene to evade responsibility after striking the plaintiff.
  

   "The defendants noted that, although the court's proposed jury instruction made reference to a special defense, it never identified that defense; in fact, the term 'superseding cause' was never used by the court. The defendants argued that they intended to reference that term in ... closing arguments and that they were entitled to a separate charge addressing their superseding cause defense. The defendants also took the position that, unlike in criminal law, tort law made no meaningful distinction between reckless and intentional conduct, and, thus, they asserted that it was inconsequential whether the criminal assault on the plaintiff was the result of intentional or reckless conduct for purposes of applying the doctrine of superseding cause.
  

   "On December 11, 2014, prior to closing arguments, the plaintiff requested that the court change the order of the proposed interrogatories. The interrogatory that the court had added regarding scope of the risk, which the court indicated related to the special defense of superseding cause, was, at the time, interrogatory number four. Interrogatory number five at that time asked whether the plaintiff had proven that some or all of her injuries were proximately caused by Sainval. The plaintiff argued that because proximate cause was an element of her prima facie case, it made more sense for the jury to answer that interrogatory and fully establish a prima facie case before turning to any consideration
   of a special defense. According to the plaintiff, this would also negate the need for a retrial in the event there was a defendants' verdict on the special defense that was overturned later on appeal; all that would be required would be a hearing in damages. The defendants did not agree that a switch was necessary. The court nevertheless indicated that it would most likely make the switch and later incorporated the change in the interrogatories it submitted to the jury. The court also indicated that it had made some additional changes based [on] the positions of the parties at the charging conference, including referring to the doctrine of superseding cause by name.
   "After the parties concluded their closing arguments, the court read its instructions to the jury. The relevant portions of the court's instructions for purposes of the present appeal are those addressing proximate causation, which provided in relevant part as follows: 'Once you've gotten past factual causation, you need to address proximate cause. Proximate cause means that there must be a sufficient causal connection between the act or omission alleged, and any injury or damage sustained by the plaintiff.
  

   " 'An act or omission is a proximate cause if it was a substantial factor in bringing about or actually causing the injury. That is, if the injury or damage was a direct result, or a reasonable and probable consequence of the defendant's act or omission, it was proximately caused by such an act or omission.
  

   " 'In other words, if an act had such an effect in producing the injury that reasonable persons would regard it as being a cause of the injury, then the act or omission is a proximate cause. In order to recover damages for any injury, the plaintiff must show by a preponderance of the evidence that such injury would not have occurred without the negligence of the defendant.
  

   " 'If you find that the plaintiff complains about an injury which would have occurred even in the absence of the defendant's conduct, or is not causally connected to this accident, you must find that the defendant did not proximately cause that injury.
  

   " 'Under the definitions I have given you, negligent conduct can be a proximate cause of an injury, if it is not the only cause, or even the most significant cause of the injury, provided it contributes materially to the production of the injury, and thus is a substantial factor in bringing it about.
  

   " 'Therefore, when a defendant's negligence combines together with one or more other causes to produce an injury, such negligence is a proximate cause of the injury if its contribution to the production of the injury, in comparison to all other causes, is material or substantial.
  

   " 'When, however, some other causal causes contributes so powerfully to the production of an injury, as to make the defendant's negligent contribution to the injury merely trivial or inconsequential, the defendant's negligence must be rejected as a proximate cause of the injury, for it has not been a substantial factor in bringing the injury about.
   
    5
   

   " 'Or to put it another way, if you find that the injury would have been sustained, whether or not the defendant had been negligent, his negligence would not have been a proximate cause of the accident. It is your responsibility to determine which, if any, of the injuries and damages claimed by the plaintiff were proximately caused by the conduct of the defendant.
  

   " 'The defendants have claimed that the theft and operation of the car by [Johnson] and [Bowden], and the resulting accident, constituted such an event, an event that was so overpowering in consequence as to render any possible negligence on the part of defendant Sainval relatively insignificant, and therefore not a proximate cause of the injuries sustained by plaintiff.
  

   " 'Foreseeability of the car being stolen, something you would have considered in connection with determining whether [Sainval]
  

   was negligent, also may be considered in this regard. It is for you to decide whether the theft of the car and subsequent manner of operation [were] so overwhelming in significance, or whether they constituted a concurrent proximate cause but not of sufficient magnitude as to render [Sainval's] negligence inconsequential.
  

   " 'To put it another way, if you find that the theft of the car and subsequent driving of the vehicle and resulting accident were intentional acts that were not within the scope of the risk which was created by [Sainval's] conduct, then the defendant[s] could not be found responsible for the injuries to the plaintiff as the conduct of [Johnson] and [Bowden] would have been the proximate cause of the injuries sustained by the plaintiff, thereby relieving the defendant[s] of any liability.
  

   " 'To the extent that you find that the plaintiff has proven, by a preponderance of the evidence, that the negligence of defendant Sainval was a proximate cause of any or all of the injuries and damages claimed to have been sustained by the plaintiff, as I have defined proximate cause to you, you are to proceed to determine the issues as to the amount of damages, following the rules I'm about to give you.'
  

   "Following the jury charge, the court inquired whether the parties had any additional objections to the charge other than those raised at the charge conference.
  

   Neither party raised any additional objections. A written copy of the court's charge was made an exhibit and provided to the jury.
  

   "The following day, the jury returned a verdict in favor of the defendants. The relevant interrogatories submitted to the jury, and the jury's response[s], are as follows: '1. Did [the] plaintiff ... prove, by a preponderance of the evidence, that ... Sainval failed to exercise reasonable care when he left the keys to his taxicab in the vehicle, when he went inside the apartment complex at Monterey Village on the evening of December 3, 2009? [Answer] Yes ... [If the answer is 'YES,' go to interrogatory #2; if the answer is 'NO,' sign and date this form and the defendants' verdict form, and then report that you have reached a verdict.] 2. Did [the] plaintiff prove that it was reasonably foreseeable that a motor vehicle, left in a parking area of Monterey Village with the key in the ignition on the evening of December 3, 2009, might be stolen? [Answer] Yes ... [If the answer is 'YES,' go to interrogatory #3; if the answer is 'NO,' sign and date this form and the defendants' verdict form, and then report that you have reached a verdict.] 3. Did [the] plaintiff prove that it was reasonably foreseeable that if a motor vehicle were to be stolen from the parking area at Monterey Village, it might be in an accident, causing injury? [Answer] Yes ... [If the answer is 'YES,' go to interrogatory #4; if the answer is 'NO,' sign and date this form and the defendants' verdict form, and then report that you have reached a verdict.] 4. Did [the] plaintiff ... prove that some or all of the injuries she sustained on the evening of December 3, 2009, were proximately caused by the negligence of ... Sainval? [Answer] Yes ... [If the answer is 'YES,' go to interrogatory #5; if the answer is 'NO,' sign and date this form and the defendants' verdict form, and then report that you have reached a verdict.] 5. Did [the] defendant[s] prove that the accident
   that occurred on December 3, 2009 was outside the scope of risk created by [Sainval's] leaving his key in the ignition of a car parked at Monterey Village? [Answer] Yes ....'
   
    6
   
   The directions contained
   in the interrogatories instructed the jury to return a defendants' verdict if it answered interrogatory five in the affirmative, and, therefore, the jury did not respond to the remainder of the interrogatories submitted. The court accepted the jury's verdict.
  

   "The plaintiff filed a postjudgment motion asking the court to set aside the verdict and to order a new trial. The plaintiff argued that, despite the jury having found that the theft of the taxicab and the subsequent accident resulting in injuries were foreseeable and that Sainval's actions were a proximate cause of her injuries, the jury instructions and attendant interrogatories permitted the jury to simultaneously and inconsistently find that her being struck by the taxicab in the manner that occurred nevertheless was outside the scope of the risk created by Sainval's negligence.
  

   "The court issued a detailed and thorough memorandum of decision denying the plaintiff's motion. The court found that there was no basis for concluding that it should not have submitted the doctrine of superseding cause to the jury in this case or that the resulting verdict and interrogatories were fatally inconsistent. The court explained that it saw 'nothing inherently inconsistent with a jury finding a "standard" proximate cause instruction satisfied, while also later finding superseding cause established when viewed from the [alternative] perspective of a charge on that point.'

   On appeal to the Appellate Court, the plaintiff claimed that the doctrine of superseding cause should not have
   been submitted to the jury because it applies only to superseding acts that were unforeseeable and intended to cause harm, and Bowden's reckless operation of the taxicab satisfied neither of those requirements.

   . The plaintiff also argued that, even if the superseding cause doctrine were applicable, the trial court's instructions misled the jury by failing to adequately define the phrase "scope of the risk" in the context of determining whether Bowden's actions were a superseding cause of the plaintiff's injuries.
   
    Id., at 68-70
   
   ,
   
    158 A.3d 787

Finally, the plaintiff maintained that the trial court improperly had denied her motion to set aside the verdict and for a new trial on the ground that the jury's finding of a superseding cause was irreconcilable with its finding that Sainval's negligence was the proximate cause of some or all of the plaintiff's injuries.

With respect to her contention that the doctrine of superseding cause applies only to intervening acts that were intended to cause harm, the Appellate Court explained that when this court abolished the superseding cause doctrine in cases involving intervening acts of negligence, it expressly exempted from its holding, among other types of intervening forces, unforeseeable "criminal event[s]";

    158 A.3d 787
   
   . With respect to the plaintiff's claim that the doctrine should not have been submitted to the jury because it applies only to superseding acts that were unforeseeable, and Bowden's recklessness represented the kind of risk that made Sainval's conduct
   negligent in the first place, the Appellate Court responded that, "even in cases in which the risk of a third party's intervention is a generally foreseeable consequence of a defendant's actions, it is
   a question of fact whether the third party's intervening actions fall somewhere within the hazard created by the defendant's negligence, i.e., within the scope of the risk. Only if the answer to that question is so abundantly clear as to be determinable as a matter of law should the court decline to give an instruction on superseding cause. Otherwise, the inquiry is a factual issue that should be presented to and decided by a jury."
   
    Id., at 61

    id., at 68
   
   ,
   
    158 A.3d 787
   
   ; concluding that, "although perhaps not perfect in all respects, the instructions were sufficient to inform the jury of the doctrine of superseding cause as pleaded and to guide the jury through its deliberation to a proper verdict."
   
    Id., at 71
   
   ,
   
    158 A.3d 787
   
   . Finally, the Appellate Court disagreed with the plaintiff that the trial court improperly denied her motion to set aside the verdict and for a new trial on the ground that the jury's response to the fourth interrogatory, that is, that some or all of the plaintiff's injuries were proximately caused by Sainval's negligence, was irreconcilable with its response to the fifth interrogatory, that is, that the accident that occurred was outside the scope of risk created by Sainval's negligence.
   
    Id., at 71-73
   
   ,
   
    158 A.3d 787
   
   . In reaching its determination, the Appellate Court relied on the definition of superseding cause set forth in § 440 of the Restatement (Second) of Torts, which "defines a superseding cause as 'an act of a third person or other force which by its intervention prevents the actor from being liable for harm to another
   
    which his antecedent negligence is a substantial factor in bringing about
   
   .' ... 2 Restatement (Second), Torts § 440, p. 465 (1965)." (Emphasis in original.)

   The Appellate Court also relied on § 442 B of the Restatement (Second) of Torts;
   
    id., at 59-61
   
   ,
   
    158 A.3d 787
   
   ; which states that, "[if] the negligent conduct of the actor creates or
   increases the risk of a particular harm and is a substantial factor in causing that harm, the fact that the harm is brought about through the intervention of another force does not relieve the actor of liability,
   
    except where the harm is intentionally caused by a third person and is not within the scope of the risk created by the actor's conduct
   
   ." (Emphasis added.) 2 Restatement (Second), supra, § 442 B, p. 469. Reading §§ 440 and 442 B together, the Appellate Court reasoned that, because the test for proximate cause is whether the defendant's conduct was "a substantial factor" in producing the plaintiff's injury; (internal quotation marks omitted)

   ("even in cases in which the risk of a third party's intervention is a generally foreseeable consequence of a defendant's actions, it is a question of fact whether the third party's intervening actions fall somewhere within the hazard created by the defendant's negligence, i.e., within the scope of the risk").
  

   In reaching its determination, the Appellate Court recognized the inherent tension
   between the Restatement's definition of superseding cause, which this court has never formally adopted,

    Barry
   
   that, "[i]f a third person's [negligence] is found to be the superseding cause of the plaintiff's injuries, that
   [negligence], rather than the negligence of the party attempting to invoke the doctrine of superseding cause,
   
    is said to be the sole proximate cause of the injury

   . The Appellate Court reasoned, however, that, because "[c]omment (b) of § 440 of the Restatement (Second) of Torts clarifies that '[a] superseding cause relieves the actor of liability, irrespective of whether his antecedent negligence was or was not a substantial factor in bringing about the harm' "; (emphasis omitted)

   59 n.15,
   
    158 A.3d 787
   
   ; it was reasonable to construe the "sole proximate cause" language in
   
    Barry
   
   "not as a repudiation of the Restatement's broader definition but simply as a recognition that, in some cases involving a superseding cause, the superseding event may so diminish the impact of the initial negligence of the defendant that that negligence can no longer be viewed as a substantial factor in bringing about the plaintiff's injury, thus transforming the superseding cause into the sole proximate cause of the harm. This iteration of the doctrine, however, does not expressly preclude that, in certain cases factually distinct from that considered by the court in
   
    Barry
   
   , the impact of the defendant's initial negligence will not be so diminished by the later intervening act as to fully negate the initial negligence as a substantial factor in causing the harm at issue. In such cases, application of the doctrine of superseding cause may nonetheless be justified to prevent an otherwise inequitable determination regarding liability."
   
    Id.
   

   On appeal following our grant of certification, the plaintiff contends that the Appellate Court incorrectly held that the doctrine of superseding cause applies to criminally reckless conduct. In support of this contention, the plaintiff asserts that the Appellate Court's
   determination conflicts with § 442 B of the Restatement (Second) of Torts, which this court has adopted, and with the Judicial Branch's model civil jury instruction on superseding causes; Connecticut Civil Jury Instructions 3.1-5, available at http://www.jud.ct.gov/JI/Civil/Civil.pdf (last visited August 5, 2019);
   
    8
   
   both of which,
   the plaintiff maintains,
   indicate that, for a third party's conduct to qualify as a superseding cause, he or she must have acted with the specific intent to cause injury. The plaintiff further contends that the Appellate Court incorrectly determined that the trial court properly denied the plaintiff's motion to set aside the verdict and for a new trial on the basis of its determination that an intervening force can be foreseeable for purposes of determining proximate cause but not within the scope of the risk for purposes of applying the superseding cause doctrine. The plaintiff argues that, under this state's well established precedent-precedent on which the trial court's jury instructions were predicated-if Sainval's negligence proximately caused some or all of the plaintiff's injuries, then the accident was, by definition, within the scope of the risk created by his negligence. See, e.g.,
   
    Sapko
   
   v.
   
    State
   
   ,
   
    305 Conn. 360
   
   , 373,
   
    44 A.3d 827
   
   (2012) ("[t]he fundamental inquiry of proximate cause is whether the harm that occurred was within the scope of foreseeable risk created by the defendant's negligent conduct" [internal quotation marks omitted] ).
  

   The defendants counter that the Appellate Court correctly determined that the jury's interrogatory responses can be reconciled by applying §§ 440 and 442 B of the Restatement (Second) of Torts, pursuant to which the jury reasonably could have found that Sainval's negligence proximately caused the plaintiff's injuries
   
    and
   
   that Bowden's and Johnson's actions were a superseding cause of the accident. The defendants further argue that, because superseding cause is a special defense that admits the allegations of a complaint but seeks to establish that the plaintiff cannot prevail; see
   
    Coughlin
   
   v.
   
    Anderson
   
   ,
   
    270 Conn. 487
   
   , 501,
   
    853 A.2d 460
   
   (2004) ("[a]s a general rule, facts must be pleaded as a special defense when they are consistent with the allegations of the complaint but demonstrate, nonetheless,
   that the plaintiff has no cause of action" [internal quotation marks omitted] ); it makes sense that "a jury must first determine that a defendant's negligence is a proximate cause of a plaintiff's injuries before it can consider whether a superseding cause ... intervened to absolve that negligent defendant of liability for those injuries." For the reasons set forth hereinafter, we conclude, contrary to the contention of the plaintiff, that the superseding cause doctrine is applicable
   to the present case. We also conclude, however, that the plaintiff is entitled to a new trial because the interrogatory responses on which the jury verdict was based are inconsistent as a matter of law.

   Whether the superseding cause doctrine applies to criminally reckless conduct presents a question of law, over which we exercise plenary review. See, e.g.,
   
    Barry
   
   v.
   
    Quality Steel Products, Inc.
   
   , supra,
   
    263 Conn. at 433-46
   
   ,
   
    820 A.2d 258
   
   (reviewing de novo trial court's decision regarding applicability of superseding cause doctrine). To properly analyze this question, it is necessary to review the legal underpinnings of the doctrine. As both the trial court and the Appellate Court observed, few other areas of tort law have consistently proven as challenging for courts to explain and for juries to apply as the principles underlying the doctrines of proximate cause and superseding cause. See, e.g.,
   
    Cuneo
   
   v.
   
    Connecticut Co.
   
   ,
   
    124 Conn. 647
   
   , 651-52,
   
    2 A.2d 220
   
   (1938) ("Few subjects have caused more trouble to courts and legal philosophers than [the question of proximate cause]. The cases on the subject are innumerable and the discussions interminable.");
   
    Snell
   
   v.
   
    Norwalk Yellow Cab, Inc.
   
   , supra,
   
    172 Conn. App. at 56
   
   ,
   
    158 A.3d 787
   
   ("although the concepts underlying the doctrine of superseding cause may be easy to identify, their application to the specifics of a particular case can be a far more difficult task"). It is well settled that a negligence action consists of four elements: duty, breach, causation, and actual injury. See, e.g.,
   
    Murdock
   
   v.
   
    Croughwell
   
   ,
   
    268 Conn. 559
   
   , 566,
   
    848 A.2d 363
   
   (2004) (identifying essential elements of negligence action). For purposes of this appeal, the defendants do not dispute that Sainval owed a duty to the plaintiff, that he breached that duty, and that the plaintiff was seriously injured. They do dispute, however, that Sainval's negligence caused the plaintiff's injuries.
   
    9
   
   Causation in a negligence action has two components, both of which must be satisfied for the plaintiff to prevail. The first, "[c]ause in fact, occasionally referred to as actual cause, asks whether the defendant's conduct 'caused' the plaintiff's injury. Thus, if the plaintiff's injury would not have occurred 'but for' the defendant's conduct, then the defendant's
   conduct is a cause in fact of the plaintiff's injury. Conversely, if the plaintiff's injury would have occurred regardless of the defendant's conduct, then the defendant's conduct was not a cause in fact of the plaintiff's injury. [W. Keeton et al., Prosser and
   Keeton on the Law of Torts] (5th Ed. 1984) § 41, p. 266."
   
    Stewart
   
   v.
   
    Federated Dept. Stores, Inc.

    234 Conn. 597
   
   , 605,
   
    662 A.2d 753
   
   (1995). In the present case, it is undisputed that Sainval's conduct was a cause in fact of the plaintiff's injuries because, if he had not left the taxicab unattended with the key in the ignition, the vehicle would not have been stolen and the plaintiff would not have been injured.
  

   The second component of causation is proximate cause. "Philosophically, cause in fact is limitless; but for the creation of this world, no crime or injury would ever have occurred. [W. Keeton, supra, § 41] p. 264. The philosophical sense of causation includes the great number of events without which any happening [of an injury] would not have occurred ... yet the effect of many of them is so insignificant that no ordinary mind would think of them as causes. 2 Restatement (Second), [supra] § 431, comment (a) [p. 429]."

   ,
   
    662 A.2d 753
   
   . "Because actual causation ... is virtually limitless, the legal construct of proximate cause serves to establish how far down the causal continuum tortfeasors will be held liable for the consequences of their actions.... The test for proximate cause is whether the defendant's conduct was a substantial factor in producing the plaintiff's injury.... This substantial factor test reflects the inquiry fundamental to all proximate cause questions, namely, whether the harm [that] occurred was of the same general nature as the foreseeable risk created by the defendant's negligence."

   We often have observed that "[p]roximate cause results from a sequence of events unbroken by a superseding cause, so that its causal viability continued until the moment of injury or at least until the advent of the
   immediate injurious force.... The terms 'intervening cause' and 'superseding cause' have been used interchangeably.... The Restatement [Second] of Torts makes clear that the doctrine is properly referred to as 'superseding cause,' and that it embodies within it the concept of an 'intervening force.' 2 Restatement (Second), [supra] §§ 440 through 453 [pp. 465-91 ]."

As we also have explained previously, "[c]auses traced clear to the end [that] become of trivial consequences, mere incidents of the operating cause, may be, in a sense, factors, but are so insignificant that the law cannot fasten responsibility [on] one who may have set them in motion. They are not substantial factors as operative causes. To be factors of this degree they must have continued down to the moment of the damage, or, at least, down to the setting in motion of the final active injurious force [that] immediately produced (or preceded) the damage."

   "[A]lthough nearly every treatise involving the law of torts acknowledges the existence of the doctrine of superseding cause, it is defined differently by various scholars. For example, one treatise notes that the problem of superseding cause is not primarily one of causation but, rather, 'one of policy as to imposing legal responsibility.' [W. Keeton, supra] § 44, p. 301.... [O]ther treatises support the view that the doctrine of superseding cause is merely a more complicated analysis of whether the defendant's actions were the proximate cause of the plaintiff's injuries. For example, one treatise states: '[Superseding] cause is merely proximate cause flowing from a source not connected with the party sought to be charged. While the term may have some descriptive value, unduly elaborate discussion of [superseding] cause as such tends to becloud rather than clarify the relatively simple idea of causal connection. When it is determined that a defendant is relieved of liability by reason of [a superseding] cause, it would appear to mean simply that the negligent conduct of someone else-and not that of the defendant-is the proximate cause of the event.' ... 1 T. Shearman & A. Redfield, Negligence (Rev. Ed. 1941) § 37, pp. 99-100." (Emphasis omitted.)

   Accordingly, "[i]f the third person's negligence is determined to be a superseding cause of the plaintiff's injury, that negligence, rather than the negligence of the party attempting to invoke the doctrine of superseding cause, is said to be the sole proximate cause of the injury.... The circumstances under which this shifting may take place have been well-defined in our case law. Even if a plaintiff's injuries are in fact caused by a defendant's negligence, a superseding cause may break that causal connection if it so entirely supersedes the operation of the defendant's negligence that it alone, without his negligence contributing thereto in any
   degree, produces the injury; or it must be the non-concurring culpable act of a human being who is legally responsible for such act.... If a defendant's negligence was a substantial factor in producing the plaintiff's injuries, the defendant would not be relieved from liability for those injuries even though another force concurred to produce them.... Whether a superseding cause was of such a character as to prevent an act of negligence of the defendant from being a substantial factor in producing a plaintiff's injury is ordinarily a question of fact [for the jury]."

   In

   was decided after the legislature's enactment of No. 86-338 of the 1986 Public Acts (Tort Reform I) and No. 87-227 of the 1987
   Public Acts (Tort Reform II), prior to which "this state followed the rules of joint and several liability with no contribution among joint tortfeasors. [Under that system, if] the illegal conduct of each of the defendants was a proximate cause of [an injury], they would be liable jointly and severally, the plaintiff would have a right to recover the entire amount of damages awarded from either, and, if he did so, the defendant paying them would have no right of contribution against the other [defendants] ....
  

   "Under the common law of joint and several liability, therefore, even a defendant whose degree of fault was comparatively small could be held responsible for the entire amount of damages, [as] long as his negligence was a proximate cause of the plaintiff's injuries. Thus, the plaintiff could collect the entire amount of his judgment
   from the richest defendant, or from the defendant with the deepest pocket....
  

   "In response largely to these concerns, the legislature undertook to reform the tort recovery provisions of our civil system, by enacting [Tort Reform I], which took effect October 1, 1986. Tort Reform I replaced the common-law rule of joint and several liability with a system of apportioned liability, holding each defendant liable for only his or her proportionate share of damages."

   Prior to
   
    Barry
   
   , the superseding cause doctrine was applied to any intervening force-be it of nature, man or beast-that a defendant claimed had superseded his own tortious conduct to such a degree that it alone was the sole proximate cause of the plaintiff's injuries. See, e.g.,
   
    Lombardi

    Wallad
   
   ,
   
    98 Conn. 510
   
   , 518,
   
    120 A. 291
   
   (1923) ("the intervening cause either must be a cause, whether intelligent or not, [that] so entirely supersedes the operation of the defendant's negligence that it alone, without his negligence contributing thereto in any degree, produces the injury");

   ,
   
    110 Conn. 184

   (1929) (
   
    Maltbie
   
   ,
   
    J.
   
   , dissenting) ("the circumstances [that] intervene may be natural phenomena, or the involuntary and unlawful act of a third person, or his negligent conduct, or his voluntary but lawful act, or his voluntary and wilfully wrong act; or some act of the injured party himself may intervene and it may be a negligent act on his part or a wilfully wrong act").
  

   In light of the significant changes to our tort system implemented by tort reform, however, this court determined in
   
    Barry
   
   "that the doctrine of superseding cause no longer serves a useful purpose in our jurisprudence when a defendant claims that a subsequent negligent
   act by a third party cuts off its own liability for the plaintiff's injuries. [In such] circumstances, superseding cause instructions serve to complicate what is fundamentally a proximate cause analysis.... [B]ecause our statutes allow for apportionment among negligent defendants; see General Statutes § 52-572h ; and because Connecticut is a comparative negligence jurisdiction; General Statutes § 52-572
   
    o
   
   ; the simpler and less confusing approach to cases ... [in which] the jury must determine which, among many, causes contributed to the [plaintiff's] injury, is to couch the analysis in proximate cause rather than allowing the defendants to raise a defense of superseding cause." (Footnote omitted.)

   ; see also
   
    id.,
   
   at 443 n.18,
   
    820 A.2d 258
   
   ("[T]he doctrine of superseding cause is already incorporated into the test for proximate cause. Repeating the test for superseding
   cause, then, merely adds confusion to an already confusing subject, and serves no meaningful purpose in a jurisdiction, such as ours, [in which] a defendant will be liable only for his or her proportion of the plaintiff's damages.")
  

   Under this approach, "the fact finder need only determine whether the allegedly negligent conduct of any actor was a proximate cause, specifically, whether the conduct was a substantial factor in contributing to the plaintiff's injuries. If such conduct is found to be a proximate cause of the plaintiff's foreseeable injury, each actor will pay his or her proportionate share pursuant to our apportionment statute, regardless of whether another's conduct also contributed to the plaintiff's injury. Put differently, the term superseding cause merely describes more fully the concept of proximate cause when there is more than one alleged act of negligence, and is not functionally distinct from the determination of whether an act is a proximate cause of the injury suffered by the plaintiff." Id., at 440,
   
    820 A.2d 258
   
   .
  

   In reaching our determination in
   
    Barry
   
   , we expressly limited our holding to cases in which "a defendant claims that its tortious conduct is superseded by a subsequent negligent act or there are multiple acts of negligence," stating that our decision did "not necessarily affect those cases [in which] the defendant claims that an unforeseeable intentional tort, force of nature, or criminal event supersedes its tortious conduct."

    Barry
   
   did not affect those types of cases. E.g.,

    305 Conn. at 377

    44 A.3d 827
   
   ("the superseding cause doctrine was largely abandoned in

   Although we did not expressly say so at the time, we exempted unforeseeable intentional torts, forces of nature and criminal events from our holding in
   
    Barry
   
   because, even under our modern tort system, apportionment of liability is not available between parties liable for negligence and parties liable on any other basis. See General Statutes § 52-572h (

   ("[W]e simply did not consider [in
   
    Barry
   
   ] whether the doctrine should be abolished in workers' compensation cases. Upon consideration of that question in the present case, we agree with the [Compensation Review Board] that the concerns that caused us to abrogate the doctrine in
   
    Barry
   
   simply are not implicated in our workers' compensation scheme, which, in contrast to our comparative negligence tort scheme, is a no-fault compensation system that imposes a form of strict liability on employers.").
   In light of the foregoing, the plaintiff cannot prevail on her claim that the doctrine of superseding cause applies only to intervening acts that were intended to cause harm. As our discussion of the relevant case law
   makes clear, the superseding cause doctrine has been applied historically to any independent, intervening force that a defendant claims was the sole proximate cause of a plaintiff's injury. Following tort reform, this court prohibited the use of the doctrine in cases in which apportionment of liability is available, not because it was incompatible with the causation principles applicable to such cases; see
   
    Barry
   
   v.
   
    Quality Steel Products, Inc.
   
   , supra,
   
    263 Conn. at
   
   443 n.18,
   
    820 A.2d 258
   
   ("the doctrine of superseding cause is already incorporated into the test for proximate cause"); but because we deemed it unnecessary in light of the statutory apportionment scheme adopted some fifteen years earlier. See
   
    id.
   
   ("[r]epeating the test for superseding cause ... merely adds confusion to an already confusing subject, and serves no meaningful purpose in a jurisdiction, such as ours, wherein a defendant will be liable only for his or her proportion of the plaintiff's damages"). As we have explained, because apportionment was unavailable prior to tort reform, ameliorative principles such as the superseding cause doctrine were developed to mitigate the harshness of a tort system that would hold a defendant liable for all of a plaintiff's damages even though his or her degree of fault may have been relatively small in comparison to other defendants. See id., at 441,
   
    820 A.2d 258
   
   (superseding cause doctrine "was ... shaped in response to the harshness of contributory negligence and joint and several liability").
  

   When applicable, the doctrine merely allows a defendant to argue, and to have the jury instructed, that it is the defendant's position that some other actor is the sole legal cause of the plaintiff's injury such that, even though the defendant's conduct may have been a cause in fact of the injury in a "but for" sense, its conduct did not contribute to the production of the injury in any meaningful sense-that is, the defendant's conduct was not a substantial factor in producing the injury
   and, thus, it was not a proximate cause of that injury. Furthermore, under our precedent, to say that the defendant's conduct was not a substantial factor in producing an injury is simply another way of saying that the injury was not within the scope of the risk created by the defendant's conduct.

   ,
   
    44 A.3d 827
   
   (" '[t]he fundamental inquiry of proximate cause is whether the harm that occurred was within the scope of foreseeable risk created by the defendant's negligent conduct' "). We agree with the Appellate Court that, as long as apportionment of liability is unavailable in cases in which a defendant claims that an intervening force is the sole legal cause of the plaintiff's injuries, the doctrine of superseding cause will continue to play a legitimate ameliorative role in our tort system.

   The plaintiff asserts, nonetheless, that our conclusion that the doctrine retains vitality in such cases is inconsonant with our past adoption of the negligence principles contained in § 442 B of the Restatement (Second) of Torts, which, as we previously indicated, states that, "[if] the negligent conduct of the actor creates or increases the risk of a particular harm and is a substantial factor in causing that harm, the fact that the harm is brought about through the intervention of another force does not relieve the actor of liability, except where the harm is intentionally caused by a third person and is not within the scope of the risk created by the actor's conduct." 2 Restatement (Second), supra, § 442 B, p. 469. Specifically, the plaintiff argues that, "under § 442 B, in order for another force to relieve the defendant of liability, that force must be both (1) intentionally caused by a third person and (2) not within the scope of the risk." To be sure, this court has applied § 442 B in cases in which a defendant has claimed that his
   or her negligence was superseded by the intentionally harmful acts of a third party. In all of the cases in which we have applied § 442 B, however, we relied on it solely for the proposition that the plaintiff could still prevail if he or she were able to establish that the intentionally harmful act was within the scope of the risk created by the defendant's negligence. See, e.g.,

   (1983) ("[our cases applying § 442 B] make it clear that the [intervening acts] of [a third party do] not [necessarily] relieve the [defendant] of liability because the trier of fact may find that the plaintiff's injury falls within the scope of the risk created by [the defendant's] negligent conduct"). As the Appellate Court explained in rejecting the plaintiff's argument predicated on § 442 B, however, "[none of these cases supports] the proposition that a superseding cause 'can only exist' in the face of conduct by a third party intended to cause harm ... [because none of them] considered or held that a specific intent to cause harm is a necessary pre-requisite to raising the doctrine of superseding cause. The cases merely recited the standard contained in § 442 B of the Restatement (Second) of Torts."

   ,
   
    158 A.3d 787
   
   .
   We note, moreover, that, although § 442 B is the Restatement section most often cited in cases involving intentionally harmful intervening acts, it does not itself govern when such acts constitute superseding causes. Sections
   
    302 B,
    
     14
    
    448
   

    15
   
   and 449
   
    16
   
   of the Restatement
   (Second) do. Comment (a) to § 442 B provides that the "rule stated in this [s]ection is a special application of the principle stated in § 435 (1),
   
    17
   
   [namely] that the fact that the actor neither foresaw nor could have foreseen the manner in which a particular harm is brought about does not prevent his liability where the other conditions necessary to it exist." (Footnote added.) 2 Restatement (Second), supra, § 442 B, comment (a), p. 469. Comment (c) to § 442 B, however, provides that "[t]he rule stated in this [s]ection
   
    does not apply
   
   where the harm of which the risk has been created or increased by the actor's conduct is brought about by the intervening act of a third person which is intentionally tortious or criminal, and is not within the scope of the risk created by the original negligence. Such tortious or criminal acts may in themselves be foreseeable, and so within the scope of the created risk, in which case the actor may still be liable for the harm,
   
    under the rules stated in §§ 448 and 449
   
   ." (Emphasis added.) Id., comment (c), p. 471.
  

   Thus, contrary to the plaintiff's contentions, § 442 B establishes that a defendant is liable "if the plaintiff's harm results from a hazard because of which the defendant's conduct was negligent";
   
    Cuneo
   
   v.
   
    Connecticut Co.
   
   , supra,
   
    124 Conn. at 651
   
   ,
   
    2 A.2d 220
   
   ; even if the harm is brought about through the intervention of a third party. As the commentary to § 442 B makes clear, however, this principle is merely an extension of the rule contained in § 435 (1) of the Restatement (Second) of Torts, namely, that, as long as the defendant's conduct was a substantial factor in producing the harm, the fact that the defendant neither foresaw nor could have foreseen the extent of the harm, or the manner in which it occurred, does
   not prevent him from being liable.

    430 A.2d 1
   
   (1980) ("[as] long as harm of the general nature as that which occurred is foreseeable there is a basis for liability even though the manner in which the accident happens is unusual, bizarre or unforeseeable"); see also

   (1998) (
   
    Berdon, J.
   
   , dissenting) (focus of foreseeability inquiry should be "on the general nature of the harm and not the specific manner in which the injury occurred or the conduct of a third party"). As the commentary also makes clear, however, the manner in which a particular harm occurred matters greatly when the harm results from the intentionally harmful act of a third party. In those circumstances, under the rules set forth in §§
   
    302 B, 448
   
   and 449 of the Restatement (Second), the defendant will be liable only if the risk created by the defendant's negligence included the hazard that the defendant's conduct would induce a third party to commit such an act.
   
    19
   
   Finally, although §§
   
    302 B, 448
   
   and 449 of the Restatement (Second) delineate when a defendant may be liable for a third party's intentionally harmful acts, those sections merely reiterate the principle set forth in §§ 442 B and 435 (1), which is the same principle that governs every section of the Restatement (Second) of Torts relating to proximate causation: liability will attach if the defendant knew or should have known that his conduct created or increased the risk that the third party would act in such a manner. See, e.g.,
   
    Doe
   
   v.
   
    Saint Francis Hospital & Medical Center
   
   ,
   
    309 Conn. 146
   
   , 190-91 n.37,
   
    72 A.3d 929
   
   (2013) ("[Section] 302 B of the Restatement (Second) of Torts does not establish a foreseeability standard that is ... different from the standard of foreseeability applicable to [other] general negligence claims. That standard does not differ from negligence case to negligence case, and there is no difference in the nature of that test for purposes of a general negligence claim, on the one hand, and a claim under § 302 B, on the other.... Like all negligence claims, § 302 B is predicated on the same general principles that govern other negligence actions, with liability in such cases depending on the foreseeability of the third party's criminal misconduct." [Internal quotation marks omitted.] ).
  

   We also disagree with the plaintiff that the Judicial Branch's model civil jury instructions on superseding cause support the conclusion that the doctrine applies only to acts that were intended to cause harm. As the Appellate Court stated in rejecting this contention, "[t]he model instructions are not intended to be authoritative. As provided on their title page, the model instructions
   are only meant to provide guidance; their legal sufficiency is not guaranteed. See Connecticut Civil Jury Instructions [supra] ('This collection of Civil Jury Instructions is intended as a guide for judges and attorneys in constructing charges and requests to charge. The use of these instructions is entirely discretionary and their publication by the Judicial
   Branch is not a guarantee of their legal sufficiency.' ...) Rather than adhering to any particular format, jury instructions must be appropriately tailored to reflect the circumstances of the particular case and to adequately guide the jury. See

   v.

   ,
   
    28 Conn. App. 449

    612 A.2d 114
   
   (1992). The language used in the model jury instructions, although instructive in considering the adequacy of a jury instruction; see

    158 A.3d 787
   
   .
  

   We note, moreover, that the model jury instructions on superseding cause found on the Judicial Branch website are revised only to 2008 and, consequently, do not reflect our subsequent cases clarifying that the superseding cause doctrine remains a viable defense in any case in which apportionment is unavailable, and that even an act of negligence can constitute a superseding cause in such a case. It is for reasons like these that we previously have cautioned that the civil jury instructions found on the Judicial Branch website are intended as a guide only, and that their publication is no guarantee of their adequacy. See, e.g.,
   
    State
   
   v.
   
    Reyes
   
   ,
   
    325 Conn. 815
   
   , 821-22 n.3,
   
    160 A.3d 323
   
   (2017) ("The Judicial Branch website expressly cautions that the jury instructions contained therein '[are] intended as a guide for judges and attorneys in constructing charges and requests
   to charge. The use of these instructions is entirely discretionary and their publication by the Judicial Branch is not a guarantee of their legal sufficiency.' " [Emphasis omitted.] ) We therefore reiterate that litigants and trial courts alike should review the relevant case law when fashioning a jury charge, whether on the basis of the instructions set forth on the Judicial Branch website or otherwise, to ensure that it conforms to any recent changes in the law.

   Having concluded that the Appellate Court correctly determined that the doctrine of superseding cause applies to criminally reckless conduct, we now must consider whether that court also was correct in concluding that the jury's responses to the fourth and fifth interrogatories are legally consistent and, therefore, that the trial court properly denied the plaintiff's motion to set aside the verdict and for a new trial. Although we ordinarily review the denial of a motion to set aside a verdict under an abuse of discretion standard; e.g.,
   
    Label Systems Corp.
   
   v.
   
    Aghamohammadi
   
   ,
   
    270 Conn. 291
   
   , 303,
   
    852 A.2d 703
   
   (2004) ; our review is plenary when, as in the present case, the trial court's decision turned on a question of law.

   , 250-51 and n.9,
   
    9 A.3d 364
   
   (2010). Furthermore, it is axiomatic that, when a party claims that the verdict should have been set aside due to the jury's inconsistent answers to interrogatories, "the court has the duty to attempt to harmonize the answers."

   v.

    525 A.2d 1332
   
   (1987).
  

   As we previously indicated, in concluding that the jury's interrogatory responses were reconcilable, the Appellate Court relied primarily on §§ 440 and 442 B of the Restatement (Second) of Torts, which it interpreted as establishing that an injury could be proximately caused by an actor's negligent conduct but not be within the scope of the risk created by that conduct. Although the Appellate Court acknowledged that its interpretation
   of these provisions of the Restatement (Second) was at odds with this court's statement in
   
    Barry
   
   that "superseding cause" is simply another way of saying "sole proximate cause," the court ultimately concluded that the "sole proximate cause" language in
   
    Barry
   
   was not intended "as a repudiation of the Restatement's broader definition" of the term and that
   
    Barry's
   
   "iteration of the doctrine ... does not expressly preclude that in certain cases factually distinct from that considered by the court in
   
    Barry
   
   , the impact of the defendant's initial negligence will not be so diminished by the later intervening act as to fully negate the initial negligence as a substantial factor in causing the harm at issue."
   
    Snell
   
   v.
   
    Norwalk Yellow Cab, Inc.
   
   , supra,
   
    172 Conn. App. at
   
   59 n.15,
   
    158 A.3d 787
   
   .
  

   We do not disagree with the Appellate Court that the fundamental policy underlying the superseding cause doctrine is essentially the same under the Restatement's explication of the doctrine and under the exposition of the doctrine found in the governing precedent of this court. As we explained, however, the terminology employed by the Restatement (Second) and by this court in explaining the doctrine are materially different. In particular, under the Restatement (Second), negligent conduct that is
   
    found to be a proximate cause of the injuries sustained
   
   may nevertheless be rendered so relatively inconsequential in light of a later superseding cause that that superseding cause is deemed to relieve the original tortfeasor of liability. Under our precedent, by contrast, a finding that conduct constitutes a superseding cause renders
   the original negligence so insignificant in relation to that superseding cause that the original negligence cannot be deemed to be a proximate cause of the injuries. Thus, our precedent simply does not contemplate a situation in which the original negligence may be found to be a substantial factor in producing the injuries if there is a finding of a superseding
   cause. Indeed, we consistently have described a superseding cause as an intervening force that "
   
    prevent
   
   [
   
    s
   
   ]
   
    an act of negligence of the defendant from being a substantial factor in producing a plaintiff's injury
   
   ...." (Emphasis added; internal quotation marks omitted.)

   Although, as the Appellate Court noted, the trial court's jury instructions were imperfect, the jury nevertheless was instructed in accordance with this court's precedent on the doctrine of superseding cause. Thus, the jury was
   
    not
   
   instructed that it could find that Sainval's negligence was a substantial factor in producing the plaintiff's injuries
   
    and
   
   that Bowden's and Johnson's actions were a superseding cause of the injuries. To the contrary, the jury was instructed that only if it found that Sainval's negligence was
   
    not
   
   a substantial factor in producing the plaintiff's injuries could it find that Bowden's and Johnson's actions were a superseding cause of those injuries. See

   v.
   
    Heil Co.
   
   , supra,
   
    203 Conn. at 605
   
   ,
   
    525 A.2d 1332
   
   ("interrogatories are not vacuous words, but words which are amplified and defined in the charge"). Specifically, the trial court informed the jury that the "defendants have claimed that the theft and operation of the car by [Johnson] and [Bowden], and the resulting accident, constituted ... an event ... that was so overpowering in consequence as to render any possible negligence on the part of ... Sainval relatively insignificant,
   
    and therefore not a proximate cause of the injuries sustained by the plaintiff
   
   ." (Emphasis added.) The court further explained that, "[w]hen ... some other causal causes [contribute] so powerfully to the production of an injury as to make the defendant's negligent contribution to the injury merely trivial or inconsequential,
   
    the defendant's negligence must be rejected as a proximate cause of the injury, for it has not been a substantial factor in bringing the injury about
   
   ." (Emphasis added.)
  

   To reinforce the latter point, the court explained that a finding of superseding cause "
   
    precludes a finding that the defendant's conduct was a proximate cause of the plaintiff's injuries
   
   " and that, "[t]o the
   extent that you find that the plaintiff has proven, by a preponderance of the evidence, that the negligence of ... Sainval was a proximate cause of any or all of the injuries and damages claimed to have been sustained by the plaintiff, as I have defined proximate cause to you,
   
    you are to proceed to determine the issues as to the amount of damages, following the rules I'm about to give you
   
   ." (Emphasis added.) Notwithstanding these instructions, the jury found
   
    both
   
   that Sainval's negligence was a proximate cause of some or all of the plaintiff's injuries
   
    and
   
   that Bowden's and Johnson's
   actions were a superseding cause of the injuries. We cannot say with any confidence, therefore, that the jury followed the trial court's instructions with respect to the issue of causation.

That action was consolidated with the present case but later was settled and withdrawn prior to trial.

    As we explain more fully in part II of this opinion, the trial court determined that "foreseeability" for purposes of determining negligence and "scope of the risk" for purposes of applying superseding cause were different concepts, in part, on the basis of § 440 of the Restatement (Second) of Torts, and the notes accompanying Connecticut Civil Jury Instruction 3.1-5, which describe "superseding cause" as "any cause intervening between the time of the defendant's allegedly tortious conduct and that of the plaintiff's claimed injury [that], although not disproving that the defendant's conduct proximately caused the plaintiff's claimed injury, prevented the defendant's conduct from being considered a legal cause of that injury." Connecticut Civil Jury Instructions 3.1-5, available at http://www.jud.ct.gov/JI/Civil/Civil.pdf (last visited August 5, 2019). Specifically, the trial court understood the latter statement to mean that the superseding cause doctrine is a special defense that admits the truth of the allegations contained in the plaintiff's complaint, including the plaintiff's contention that the defendant's negligence proximately caused the plaintiff's injuries, but seeks to demonstrate that the plaintiff cannot prevail against the defendant.
   

    This paragraph of the jury charge, along with the four paragraphs of the charge that follow, represents the trial court's instructions on superseding cause, even though the court did not expressly use the term "superseding cause" in those paragraphs.
   

    Although the fifth interrogatory contains no express reference to the term "superseding cause," it is that doctrine that is the subject thereof.
   

    Although we have never adopted the Restatement's definition of superseding cause, we note that it has appeared as dicta in a handful of this court's opinions. See, e.g.,

    (2002).
   

    Connecticut Civil Jury Instruction 3.1-5 provides: "The defendant claims that he did not legally cause the plaintiff's alleged injury because that injury was produced, in material part, by a superseding cause. A superseding cause is any intentionally harmful act, force of nature, or criminal event, unforeseeable by the defendant, [that] intervenes in the sequence of events leading from the defendant's alleged negligence to the plaintiff's alleged injury and proximately causes that injury. Under our law, the intervention of such a superseding cause prevents the defendant from being held liable for the plaintiff's injury on the theory that, due to such superseding cause, the defendant did not legally cause the injury even though (his/her) negligence was a substantial factor in bringing the injury about. Therefore, when a claim of superseding cause is made at trial, the plaintiff must disprove at least one essential element of that claim by a fair preponderance of the evidence in order to prove, by that standard, its own conflicting claim of legal causation.
   

    "In this case, the defendant claims, more particularly, that <
    
     describe alleged intervening conduct or event claimed to constitute a superseding cause
    
    > was a superseding cause of the plaintiff's alleged injury, and thus that (his/her) own negligence did not legally cause that injury. Because such intentionally harmful (conduct/force of nature/criminal event), if unforeseeable by the defendant, would constitute a superseding cause of the plaintiff's alleged injury if it occurred as claimed by the defendant and if it proximately caused the plaintiff's injury, the plaintiff must disprove at least one essential element of that claim by a fair preponderance of the evidence in order to prove that the defendant legally caused that injury. The plaintiff can meet this burden by proving either 1) that the conduct claimed to constitute a superseding cause did not occur as claimed by the defendant, either because it did not occur at all or because it was not engaged in with the intent to cause harm; or 2) that such conduct was foreseeable by the defendant, in that the injury in question was within the scope of the risk created by the defendant's conduct; or 3) that such conduct was not a substantial factor in bringing about the plaintiff's alleged injury. These, of course, are questions of fact for you to determine based on the evidence. Keep in mind, however, that the defendant does not have any burden to prove the existence of a superseding cause. The burden at all times rests [on] the plaintiff to disprove the defendant's claim of superseding cause as a necessary part of (his/her) proof that the defendant legally caused the plaintiff's injury." (Emphasis in original.)
   

    Although the legal question of whether Sainval owed a duty to the plaintiff is not before us, we previously have stated that, when a defendant claims that an independent intervening force superseded his own negligence, "the question of legal causation is practically indistinguishable from an analysis of the extent of the tortfeasor's duty to the plaintiff."

    . As this court, quoting Prosser and Keeton on the Law of Torts, has explained: " '[T]he question whether there is a duty has most often seemed helpful in cases [in which] the only issue is in reality whether the defendant stands in any such relation to the plaintiff as to create any legally recognized obligation of conduct for the plaintiff's benefit. Or, reverting again to the starting point, whether the interests of the plaintiff are entitled to legal protection at the defendant's hands against the invasion [that] has in fact occurred. Or, again reverting, whether the conduct is the "proximate cause" of the result. The circumlocution is unavoidable, since all of these questions are, in reality, one and the same.' [W.

    , 37,
    
     946 A.2d 839
    
    (2008), we rejected a nearly identical claim to that which we found persuasive in
    
     Sapko
    
    , namely, that the trial court improperly had denied the defendant's request to charge the jury on the doctrine of superseding cause, when the defendant had argued that the negligence of the plaintiff's employer was the sole proximate cause of the plaintiff's injuries. In that case, the exclusivity provision of the Workers' Compensation Act had prevented the defendant from citing in the plaintiff's employer as an apportionment defendant. See id., at 26,
    
     946 A.2d 839
    
    . In support of its claim that the trial court improperly had denied its request to charge the jury on the superseding cause doctrine, the defendant argued "that our holding in
    
     Barry
    
    is restricted to cases in which the jury is charged with apportioning liability between multiple defendants and that ... the doctrine remains viable when, as in the present case, contributory negligence and apportionment of liability between two or more defendants are not at issue." Id., at 44,
    
     946 A.2d 839
    
    . In rejecting this claim, we relied solely on the fact that the doctrine had been abandoned in
    
     Barry
    
    , "subject only to certain narrow exceptions," which did not include intervening acts of negligence.
    
     Id.
    
    We agreed with the defendant, however, that the trial court improperly had precluded it from presenting evidence and argument to the jury that the plaintiff's employer was the sole proximate cause of the plaintiff's injuries. See id., at 33,
    
     946 A.2d 839
    
    ("[t]his court has determined that a defendant has the right, under a general denial, to introduce evidence that the negligence of another was the sole proximate cause of the plaintiff's injury"). Specifically, we concluded that, "if the [nonparty] employer's actions are the sole proximate cause of the [plaintiff's] injuries, then it follows that the defendant's conduct is not a proximate cause, and the defendant should be entitled to argue and have the jury instructed accordingly ...." (Internal quotation marks omitted.) Id., at 38,
    
     946 A.2d 839
    
    , quoting

    , 8,
    
     579 N.W.2d 563
    
    (1998). Of course, it was a legal distinction without a difference to conclude, on the one hand, that the defendant was prohibited from arguing that the plaintiff's employer was a superseding cause of the plaintiff's injuries and, on the other hand, that the defendant properly could argue that the employer was the sole proximate cause of the plaintiff's injuries and was entitled to an instruction with respect to this claim. This is so because, as our discussion of the case law makes clear, when a defendant is relieved of liability on the basis of a superseding cause, "it ... mean[s] simply that the negligent conduct of someone else-and not that of the defendant-is the proximate cause of the event."

     148 A.2d 760
    
    (1959) (explaining that superseding cause and sole proximate cause are indistinguishable concepts).
   

    Thus, in light of our precedent and the trial court's instructions predicated on that precedent, we disagree with the Appellate Court that the jury properly could find simultaneously that Sainval's actions were a proximate cause of the plaintiff's injuries and that Bowden's and Johnson's actions were a superseding cause of those same injuries. As we explain more fully in part II of this opinion, under our case law, a finding that conduct constitutes a superseding cause renders the original negligence so insignificant in relation to that superseding cause that the original negligence cannot be deemed to be a proximate cause of the injuries and, therefore, cannot be deemed to be a substantial factor in producing the injuries.
   

    We note that the plaintiff urges us to adopt § 34 of the Restatement (Third) of Torts, published in 2010, which she asserts "merges the viable concepts related to superseding cause (foreseeability and proximate cause) officially into a [single] proximate cause (or scope of liability) analysis without the confusion and prejudice related to use of the superseding cause doctrine." Section 34 of the Restatement (Third) provides: "When a force of nature or an independent act is also a factual cause of harm, an actor's liability is limited to those harms that result from the risks that made the actor's conduct tortious." 1 Restatement (Third), Torts, Liability for Physical and Emotional Harm § 34, p. 569 (2010). Because the plaintiff did not raise this claim in either the trial court or the Appellate Court, it is not properly before us. Even if it were, however, as the Appellate Court noted, our recent case law "reflects a jurisprudential move toward embracing" the more modern approach to superseding cause prescribed in § 34 of the Restatement (Third) of Torts.

    57 n.13,
    
     158 A.3d 787
    
    . Indeed, the reporters' notes to that section cite this court as one of several courts that
    
     have
    
    embraced the modern approach. See, e.g., 1 Restatement (Third), supra, § 34, reporters' note to comment (c), p. 579. For the reasons previously set forth, however, we are not prepared to abandon the superseding cause doctrine even in cases in which apportionment of liability is statutorily prohibited, and we do not read the Restatement (Third) as advocating its abandonment in such circumstances. To the contrary, comment (c) to § 34 provides that "the advent of comparative principles has
    
     reduced the role for superseding cause
    
    " such that "when third persons ... are negligent or commit intentional torts, the need for aggressive use of superseding cause to absolve a tortfeasor from liability has subsided
    
     in light of the modification of joint and several liability and of the trend toward permitting comparative responsibility to be apportioned among negligent and intentional tortfeasors
    
    . Comparative responsibility permits liability to be apportioned among multiple tortfeasors and to take account of the causal relationship between each tortfeasor's conduct and the harm as well as the culpability of each tortfeasor." (Emphasis added.) 1 Restatement (Third), supra, § 34, comment (c), pp. 571-72.

We rejected the defendant's claim because the trial court, in addition to instructing the jury in accordance with § 442 B, also had instructed the jury that "[
    
     a
    
    ]
    
     ny intervening negligence by

    ,

     either
    
    an intentional
    
     or
    
    a negligent act under the defendants' theory of defense, we affirmed the judgment in favor of the plaintiff.
   

    Section 302 B of the Restatement (Second) of Torts provides: "An act or an omission may be negligent if the actor realizes or should realize that it involves an unreasonable risk of harm to another through the conduct of the other or a third person which is intended to cause harm, even though such conduct is criminal." 2 Restatement (Second), supra, § 302 B, p. 88.
   

    Section 448 of the Restatement (Second) of Torts provides: "The act of a third person in committing an intentional tort or crime is a superseding cause of harm to another resulting therefrom, although the actor's negligent conduct created a situation which afforded an opportunity to the third person to commit such a tort or crime, unless the actor at the time of his negligent conduct realized or should have realized the likelihood that such a situation might be created, and that a third person might avail himself of the opportunity to commit such a tort or crime." 2 Restatement (Second), supra, § 448, p. 480.
   

    Section 449 of the Restatement (Second) of Torts provides: "If the likelihood that a third person may act in a particular manner is the hazard or one of the hazards which makes the actor negligent, such an act whether innocent, negligent, intentionally tortious, or criminal does not prevent the actor from being liable for harm caused thereby." 2 Restatement (Second), supra, § 449, p. 482.
   

    Section 435 of the Restatement (Second) of Torts, entitled "Foreseeability of Harm or Manner of Its Occurrence," provides in relevant part: "If the actor's conduct is a substantial factor in bringing about harm to another, the fact that the actor neither foresaw nor should have foreseen the extent of the harm or the manner in which it occurred does not prevent him from being liable." 2 Restatement (Second), supra, § 435 (1), p. 449.

     Ruiz
    
    , a small child was injured when an older child unintentionally dropped a piece of concrete on her head from the third floor landing of the apartment building where the children resided. Id., at 323,
    
     107 A.3d 381
    
    . The older child had obtained the concrete from the backyard of that apartment building, where he and the victim had been playing.
    
     Id.
    
    The trial court granted the defendant landlord's motion for summary judgment, concluding that the defendant owed the victim no duty of care "because no reasonable juror could find that her injuries were a foreseeable consequence of the defendant's [failure to maintain the property in a clean and safe condition by leaving loose pieces of concrete in the backyard] and because imposing liability on the defendant would be contrary to overriding public policy considerations."
    
     Id.
    
    The Appellate Court reversed the judgment of the trial court, and we affirmed the Appellate Court's judgment; id., at 323-24,
    
     107 A.3d 381
    
    ; explaining that the defendant "does not dispute that the risk of harm created by its failure to remove the buckets, trash, broken concrete pieces and other debris from the backyard was that children playing in the area might trip on them or throw them at other children. The types of injuries one would expect to result from this type of behavior run the gamut from cuts and bruises to broken bones, concussions and even fractured skulls. [The child's] injuries, although severe, fall squarely along this continuum of harm. That they occurred in an unusual manner, namely, by a child dropping a piece of concrete into the backyard playground from a third floor balcony instead of throwing it while in the backyard, does not alter this fundamental fact. We therefore agree with the Appellate Court that [the child's] injuries were sufficiently foreseeable that it was inappropriate for the trial court to foreclose the foreseeability question as a matter of law."

    As § 442 B of the Restatement (Second) of Torts indicates, however, if all of the facts were the same except that an adult intentionally had dropped the concrete on the child's head, the defendant's liability would turn on whether an adult committing such an act was within the scope of the risk created by the defendant's failure to remove the accumulated debris from its property. Such a case undoubtedly would be resolved in the defendant's favor on a motion for summary judgment because it seems clear that a jury reasonably could not find that such an act was a foreseeable risk of the defendant's negligence.
   

    Section 442 B provides a good illustration of this principle. "A negligently leaves an excavation in a public sidewalk, creating the risk that a traveler on the sidewalk will fall into it. B, passing C on the sidewalk, negligently bumps into him, and knocks him into the excavation. A is subject to liability to C." 2 Restatement (Second), supra, § 442 B, illustration (5), p. 471. If, however, all of the facts are the same except that B intentionally pushes C into the hole, A would not be liable. Id., illustration (7), p. 471. This is true even though the injuries sustained by C in the second example are identical to the injuries sustained in the first. A is not liable in the second instance because the hazard that made A's conduct negligent did not include the risk that a third party would be induced to push someone into the excavated area.

    (private landowner was not liable for sexual assault that occurred behind overgrown vegetation on landowner's property because it was not reasonably foreseeable that such vegetation would provide incentive and shield for commission of such assault when "there was no evidence tending to demonstrate that the [landowner] had had any past experience that might reasonably have led him to perceive and act on the atypical association between 'natural shields' such as overgrown vegetation and violent criminal activity");

    (1987) ("When [the driver] left the keys in the unlocked car in a high crime area, it may well have been a foreseeable risk that the car would be stolen by a third party and negligently operated so as to cause harm to an innocent party.... It was not also foreseeable, however, that a third party would steal the car, drive elsewhere, leave the car, enter a store, commit an armed robbery, and assault an innocent person in the course of that robbery. To hold otherwise would be to convert the imperfect vision of reasonable foreseeability into the perfect vision of hindsight." [Citation omitted.] )
   

    No doubt this problem stems, at least in part, from the admonition at the conclusion of the fourth interrogatory, which, in direct contradiction to the court's charge, effectively instructed the jury to consider, in connection with the fifth interrogatory, whether "the accident that occurred ... was outside the scope of the risk created by [Sainval's] leaving his key in the ignition" only if it had found, in response to the fourth interrogatory, that the plaintiff had proven "that some or all of the injuries she sustained ... were proximately caused by the negligence of ... Sainval." In accordance with the court's charge, however, once the jury found that Sainval's negligence was a proximate cause of the accident, there could be no finding of a superseding cause. Thus, the interrogatories merely should have queried the jury whether the plaintiff had proven that Sainval's negligence was a proximate cause of the plaintiff's injuries

    , whether Bowden's recklessness in driving onto a sidewalk after striking a vehicle in front of him fell outside the scope of the risk created by Sainval's negligence because it was not reasonably foreseeable that someone stealing the taxicab would operate it in such a manner.
