LOYOLA UNIVERSITY OF CHICAGO et al., Appellees." ], "opinions": [ { "text": "JUSTICE FREEMAN\ndelivered the opinion of the court:\nPlaintiffs, Rose Leonardi, as administrator of the estate of Michela Lopez, and Francesco Lopez, brought a medical malpractice action in the circuit court of Cook County. Defendants included Loyola University of Chicago and several additional corporations and individual physicians. The trial court entered judgment on a jury verdict in favor of defendants.\nThe appellate court affirmed. (262 Ill. App. 3d 411.) We allowed plaintiffs\u2019 petition for leave to appeal (145 Ill. 2d R. 315(a)), and now affirm the appellate court.\nBACKGROUND\nThe record shows that on the morning of September 1, 1979, decedent, Michela Lopez, was 36 years old and seven months pregnant. Her water broke and she was taken to a hospital. Decedent\u2019s attending physician, Dr. Thomas Tierney, had her transferred to Foster G. Mc-Gaw Hospital at Loyola University Medical Center (Loyola). Loyola was better able to deal with the most premature infants in need of intensive services and equipment. Decedent herself was not ill or at risk. However, her pregnancy was considered high risk, which required monitoring, due to the age of the fetus and because her water broke prematurely.\nOn the night of September 3, a nurse noticed heavy bleeding from decedent\u2019s vagina and paged a doctor. Dr. Joseph Coughlin, a Loyola resident, arrived seconds later and determined that decedent was hemorrhaging. Dr. John Gallagher, the senior Loyola resident on call that evening, arrived seconds after Dr. Coughlin. As senior resident, Dr. Gallagher supervised and managed a case until he received specific instructions from the attending physician or the attending physician was physically present.\nAt 9:35 p.m., Dr. Gallagher had decedent transferred to the labor and delivery room. The transfer was accomplished in less than two minutes. Decedent was in hypovolemic shock due to the loss of blood. She was receiving intravenous fluids less than three minutes after being brought to the labor and delivery room. Decedent\u2019s condition stabilized. She was alert with normal signs.\nDr. Tierney was not at the hospital when decedent was admitted. However, he instructed Loyola staff by telephone not to perform a Cesarean section until he arrived. Dr. Tierney also ordered Dr. Gallagher to perform a vaginal inspection. Dr. Gallagher\u2019s examination confirmed the existence of a placenta previa. This is a condition where the placenta is found in the lower part of the uterus rather than in its normal place in the upper part of the uterus. Where the condition is present, the placenta is partially in front of the infant, obstructing the cervix and thereby preventing the infant from coming through the cervix.\nDr. Tierney arrived at the hospital and, assisted by Dr. Henry Davis, a Loyola resident, performed a Cesarean section on decedent. At 9:58 p.m., decedent gave birth to a two-pound baby girl, Rose Angela Lopez.\nWhen Dr. Tierney attempted to remove the placenta, massive bleeding occurred. A portion of decedent\u2019s uterine wall came away with placenta that adhered to it. Decedent again went into hypovolemic shock. Dr. Tierney discovered a placenta accreta, which is an abnormal adherence of the placenta to the uterine wall. The condition required Dr. Tierney to perform a hysterectomy. The massive bleeding continued during the operation. However, at the end of the Cesarean section and hysterectomy, decedent was awake, her blood pressure and pulse were stable, and her urine output was satisfactory.\nDrs. Kanteerava Balasaraswathi and Wanda Mazurek administered general anesthesia for the surgery. Dr. Balasaraswathi extubated decedent, i.e., removed the endotracheal tube that connected decedent to the respirator. Decedent was transferred to the recovery room, where she was given supplemental oxygen by mask. She was in critical but stable condition.\nOn September 4, at 6 a.m., Dr. Roberta Karlman, a Loyola resident, ordered that decedent\u2019s oxygen mask be removed. Dr. Karlman planned to get decedent back to breathing normal air. At 8 a.m., decedent began to grow restless. By 9:30 a.m., decedent had cyanotic lips and was perspiring heavily, was restless, and complained of abdominal pain. These symptoms were consistent with a patient who recently underwent a large abdominal procedure and experienced massive blood loss. At 10:30 a.m., a blood gas test revealed that decedent was experiencing respiratory difficulties. Decedent was given supplemental oxygen by mask, which appeared to stabilize her.\nHowever, at approximately 11 a.m., decedent\u2019s blood pressure dropped significantly. At 11:35 a.m., decedent suffered respiratory arrest. The doctors believed that the cause was a saddle block pulmonary embolus, which is a blood clot at the point of separation of two blood vessels. Until this time, decedent had not shown any signs of pulmonary embolism.\nAt 11:40 am., Dr. Roque Pifarre performed an emergency pulmonary embolectomy. The operation required Dr. Pifarre to break decedent\u2019s sternum and massage the embolus, which had lodged at the very beginning of the pulmonary artery and impeded blood flow to the arteries. The clot broke into many pieces that dispersed through the arteries. Decedent\u2019s life was saved, but she suffered irreversible brain damage. She was discharged from Loyola over a year later, on October 17, 1980.\nOn October 20, 1980, decedent was admitted to the Norridge Nursing Center. During her stay there, decedent could not independently perform any activity of daily living, e.g., walking, eating, dressing, etc. She lacked bladder and bowel control. Although she could smile when happy, she could not articulate words; she could make only unintelligible noises. Decedent\u2019s arms and legs were severely bent and were unable to be straightened. Decedent would cry out in pain when her arms and legs were moved for physical therapy. Decedent died on January 25, 1985.\nPlaintiffs eventually filed a fourth-amended complaint against several defendants, including Loyola and certain resident physicians, Drs. Gallagher, Coughlin, Davis, and Mazurek; and Dr. Balasaraswathi and his corporate employer. Dr. Tierney died subsequent to the bringing of this lawsuit; his estate was substituted as a defendant. Prior to jury selection, plaintiffs settled with Dr. Tierney\u2019s estate, which was dismissed from this lawsuit.\nThe complaint contained survival counts that alleged damages for injuries to decedent as a result of the negligent Cesarean section, administration of anesthesia for the Cesarean section, and resuscitation. The complaint also contained wrongful death counts that alleged damages for injuries to decedent\u2019s next of kin as a result of the same negligent acts.\nThe jury returned a verdict for defendants and the trial court entered judgment thereon. The appellate court affirmed. (262 Ill. App. 3d 411.) Plaintiffs appeal. We will refer to additional pertinent facts as they relate to the issues plaintiffs raise before this court.\nDISCUSSION\nPlaintiffs present four issues in this appeal. They contend the trial court erred by: (1) allowing defendants to present evidence of Dr. Tierney\u2019s conduct, despite that he was not a party at trial; (2) tendering to the jury an instruction on sole proximate cause; and (3) permitting defendants to improperly cross-examine plaintiffs\u2019 medical experts. Plaintiffs also contend (4) that the jury\u2019s verdict was against the manifest weight of the evidence.\nI. Evidence of Dr. Tierney\u2019s Conduct\nPlaintiffs assign error to the trial court\u2019s evidentiary rulings on (A) a motion in limine and (B) a hypothetical question to an expert witness, both regarding the conduct of Dr. Tierney. Of course, the admissibility of evidence is a matter for the sound discretion of the trial court, and its decision will not be reversed on appeal unless that discretion has been clearly abused. Gill v. Foster (1993), 157 Ill. 2d 304, 312-13.\nA. Motion In Limine\nPrior to trial, the trial court denied plaintiffs\u2019 motion in limine to bar the introduction of evidence regarding the alleged negligence of any person other than the named defendants. At trial, the court allowed defendants to question several witnesses regarding Dr. Tierney\u2019s duties and responsibilities as decedent\u2019s attending physician. The appellate court upheld the trial court\u2019s ruling. 262 Ill. App. 3d at 415-16.\nPlaintiffs contend that evidence of Dr. Tierney\u2019s conduct was irrelevant and, therefore, inadmissible. Indeed, plaintiffs oppose the concept of the \"empty chair\u201d defense, also known as and hereafter referred to as the sole proximate cause defense. This defense seeks to defeat a plaintiff\u2019s claim of negligence by establishing proximate cause in the act of solely another not named in the suit. Hall v. Clark (Mo. 1957), 298 S.W.2d 344, 348; Fabian v. Minster Machine Co. (1992), 258 N.J. Super. 261, 276-77, 609 A.2d 487, 495.\nIn attacking the sole proximate cause defense, plaintiffs rely on the common law principle that there can be more than one proximate cause of an injury, and that a person is liable for his or her negligent conduct whether it contributed wholly or partly to the plaintiff s injury as long as it was one of the proximate causes of the injury. (Nelson v. Union Wire Rope Corp. (1964), 31 Ill. 2d 69, 88.) A person who is guilty of negligence cannot avoid responsibility merely because another person is guilty of negligence that contributed to the same injury. Where such guilt exists, it is no defense that some other person or thing contributed to the injury. Thus, evidence of another person\u2019s liability is irrelevant to the issue of defendant\u2019s guilt. See Kochan v. Owens-Corning Fiberglass Corp. (1993), 242 Ill. App. 3d 781, 788-89, quoting Lipke v. Celotex Corp. (1987), 153 Ill. App. 3d 498, 509.\nPlaintiffs\u2019 reliance on this principle is misplaced. This principle presumes that a defendant\u2019s conduct is at least a proximate cause of the plaintiffs injury. (See Restatement (Second) of Torts \u00a7 433B, Comment g (1965).) In the present case, defendants denied that they were even partly a proximate cause of plaintiffs\u2019 injuries. Rather, the defense theory was that Dr. Tierney was the sole proximate cause of plaintiffs\u2019 injuries.\nPlaintiffs insist that defendants\u2019 general denial of negligence is insufficient to raise the sole proximate cause defense. Plaintiffs maintain \"that defendants should be required to plead sole proximate cause of a non-party as an affirmative defense.\u201d\nThis contention is erroneous. In any negligence action, the plaintiff bears the burden of proving not only duty and breach of duty, but also that defendant proximately caused plaintiffs injury. (Smith v. Eli Lilly & Co. (1990), 137 Ill. 2d 222, 232; see 1 M. Polelle & B. Ottley, Illinois Tort Law \u00a7 14.23 (2d ed. 1994).) The element of proximate cause is an element of the plaintiff s case. The defendant is not required to plead lack of proximate cause as an affirmative defense. (Korando v. Uniroyal Goodrich Tire Co. (1994), 159 Ill. 2d 335, 344 (products liability).) Obviously, if there is evidence that negates causation, a defendant should show it. However, in granting the defendant the privilege of going forward, also called the burden of production, the law in no way shifts to the defendant the burden of proof. See Caley v. Manicke (1961), 29 Ill. App. 2d 323, 328-29, rev\u2019d on other grounds (1962), 24 Ill. 2d 390; M. Graham, Cleary & Graham\u2019s Handbook of Illinois Evidence \u00a7 301.4 (6th ed. 1994).\nBased on these principles, we agree with the appellate court that \"an answer which denies that an injury was the result of or caused by the defendant\u2019s conduct is sufficient to permit the defendant in support of his position to present evidence that the injury was the result of another cause\u201d (Simpson v. Johnson (1977), 45 Ill. App. 3d 789, 795), and so hold. Accord Burrows v. Jacobsen (1981), 209 Neb. 778, 782, 311 N.W.2d 880, 883-84; Clement v. Rousselle Corp. (Fla. Dist. Ct. App. 1979), 372 So. 2d 1156, 1158; Dickman v. Truck Transport, Inc. (Iowa 1974), 224 N.W.2d 459, 467; Birmingham v. Smith (Mo. 1967), 420 S.W.2d 514, 516-17.\nCiting Ruesch v. Richland Memorial Hospital (1994), 260 Ill. App. 3d 49, plaintiffs argue that the sole proximate cause defense distracts a jury\u2019s attention from the simple issue of whether a named defendant caused, wholly or partly, a plaintiff\u2019s injury. We disagree. The sole proximate cause defense merely focuses the attention of a properly instructed jury (which instruction we will discuss later) on the plaintiff\u2019s duty to prove that the defendant\u2019s conduct was a proximate cause of plaintiff\u2019s injury. (See Fabian, 258 N.J. Super. at 276-77, 609 A.2d at 495.) Decisions that contain statements to the contrary, such as in Ruesch, are overruled on this point.\nWe cannot say that the trial court clearly abused its discretion in denying plaintiffs\u2019 motion in limine. Consequently, we find no error in defendants\u2019 questioning of witnesses concerning Dr. Tierney\u2019s duties and responsibilities.\nB. Hypothetical Question\nPlaintiffs also argue that the trial, court erred by refusing to strike a hypothetical question regarding Dr. Tierney\u2019s conduct. As part of their case in chief, plaintiffs called a defendant, Dr. Balasaraswathi, one of decedent\u2019s anesthesiologists. (See 735 ILCS 5/2\u20141102 (West 1994).) He testified as follows. On September 4, 1979, at 9:30 a.m., when decedent had cyanotic lips and was perspiring heavily, was restless, and complained of abdominal pain, the physician or nurse who was taking care of decedent should have, based on accepted medical practice, immediately administered to decedent oxygen and a blood gas test. Decedent\u2019s symptoms indicated, inter alla, a pulmonary embolism.\nDuring defendants\u2019 cross-examination, Dr. Balasaraswathi testified that Dr. Tierney was decedent\u2019s treating physician. Also, Dr. Balasaraswathi was referring in his direct examination to Dr. Tierney as someone who might have deviated from the standard of care. Defense counsel then asked Dr. Balasaraswathi:\n\"Q. Now if \u2014 and I will connect this up, your Honor.\nIf Dr. Tierney was notified, and an obstetrical resident was there and wanted to draw a blood gas, and Dr. Tierney countermanded the order and told the obstetrical resident that she could not, it would be Tierney who was causing that blood gas not to be drawn; is that right?\u201d\nAfter a sidebar on plaintiffs\u2019 objection, defendants\u2019 cross-examination continued:\n\"THE COURT: *** You may read the question back, please.\n* * *\nTHE WITNESS: Yes, sir.\n[Defense Counsel:] And if the failure to have a blood gas was a deviation from the standard, then the one who prevented it from being drawn would be the one who had deviated; is that correct?\nA. That\u2019s right.\u201d\nAt the close of the evidence, the trial court denied plaintiffs\u2019 motion to strike the hypothetical question. Plaintiffs view the hypothetical question as stating that at 9:30 a.m. on September 4, 1979, Dr. Tierney countermanded an order issued by a resident to obtain a blood gas sample. Plaintiffs contend that the hypothetical question was not supported by the record and, consequently, the trial court erred by refusing to strike it.\nCounsel has a right to ask an expert witness a hypothetical question that assumes facts that counsel perceives to be shown by the evidence. (Coriell v. Industrial Comm\u2019n (1980), 83 Ill. 2d 105, 110.) The assumptions contained in the hypothetical question must be based on direct or circumstantial evidence, or reasonable inferences therefrom. (Smith\u2019s Transfer Corp. v. Industrial Comm\u2019n (1979), 76 Ill. 2d 338, 350.) The hypothetical question should incorporate only the elements favoring his or her theory, and should state facts that the interrogating party claims have been proved and for which there is support in the evidence. On cross-examination, the opposing party may substitute in the hypothetical those facts in evidence that conform with the opposing party\u2019s theory of the case. Coriell, 83 Ill. 2d at 110-11.\nIt is within the sound discretion of the trial court to allow a hypothetical question, although the supporting evidence has not already been adduced, if the interrogating counsel gives assurance it will be produced and connected later. Evidence admitted upon an assurance that it will later be connected up should be excluded upon failure to establish the connection. Coriell, 83 Ill. 2d at 111; People v. Smith (1912), 254 Ill. 167, 173-74.\nApplying these principles to the present case, we agree with the appellate court that the hypothetical question at issue had sufficient support in the evidence. However, more evidence was required to support the hypothetical question than what the appellate court cited. As a reviewing court, we can sustain the decision of a lower court on any grounds which are called for by the record, regardless of whether the lower court relied on those grounds and regardless of whether the lower court\u2019s reasoning was correct. Bell v. Louisville & Nashville R.R. Co. (1985), 106 Ill. 2d 135,148; see Werner v. Botti, Marinaccio & DeSalvo (1990), 205 Ill. App. 3d 673, 679.\nThe appellate court cited the testimony of plaintiffs\u2019 expert, Dr. Hau Kwaan, and of Dr. Balasaraswathi. (262 Ill. App. 3d at 416.) Dr. Kwaan testified that Dr. Tierney, as the treating physician, was in charge of decedent and was responsible for whatever was necessary to be done. Thus, according to Dr. Kwaan, a resident was required to follow Dr. Tierney\u2019s orders.\nHowever, the appellate court misapprehended the testimony of Dr. Balasaraswathi. He testified that on September 4, 1979, at 9:30 a.m., Dr. Tierney might have deviated from the standard of care by failing to immediately administer to decedent a blood gas test. The appellate court characterized Dr. Balasaraswathi as testifying that Dr. Tierney deviated from the standard of care by preventing a blood gas test from being taken. We earlier quoted the disputed hypothetical question to Dr. Balasaraswathi. As is seen, the reference to preventing the blood gas test from being taken was not Dr. Balasaraswathi\u2019s testimony; rather, it was a continuation of the hypothetical question itself.\nIn sum, the expert testimony establishes at most that: (1) Dr. Tierney might have deviated from the standard of care by failing to immediately administer a blood gas test, and (2) a resident was required to follow Dr. Tierney\u2019s orders. This testimony, alone, does not support the hypothetical question that Dr. Tierney countermanded a resident\u2019s order to take a blood gas test.\nHowever, defendants sought to further support the hypothetical question with the additional testimony of two Loyola senior residents, Drs. John Payne and John Gianopoulos, and a Loyola resident, Dr. Marguerita Hefti. Sustaining plaintiffs\u2019 objections, the trial court ruled that the portions of their testimony that related to the hypothetical question were inadmissible hearsay. Defendants made offers of proof of the excluded testimony.\nDr. Payne testified in an offer of proof as follows. On the morning of September 4, 1979, Dr. Payne was paged to come to decedent\u2019s bedside. Dr. Hefti paged Dr. Payne because she had a dispute with Dr. Tierney. Dr. Hefti wanted to test decedent\u2019s blood gases, but Dr. Tierney did not. Dr. Payne contacted the department chairman, who ordered Dr. Payne to see the patient and render the appropriate care.\nDr. Gianopoulos testified in an offer of proof as follows. On the morning of September 4, he accompanied Dr. Payne to decedent\u2019s bedside. Later that morning, Dr. Hefti told Dr. Gianopoulos that at 9:30 a.m., she believed that decedent should have received a blood gas test. However, Dr. Tierney ordered her not to do anything until Dr. Nemickas arrived. Dr. Hefti was frustrated because she had never heard of that physician.\nDr. Hefti testified in an offer of proof as follows. She did not remember the exact exchange between herself and Dr. Tierney, or exactly what she said to Dr. Gianopoulos. However, she did remember speaking to Dr. Gianopoulos at decedent\u2019s bedside, and that the conversation involved both Dr. Tierney and the identity of Dr. Nemickas.\nDefendants assign error to the trial court\u2019s exclusion of this testimony. We agree. The principles are quite settled. An out-of-court statement that is offered as proof of the matter asserted in court is hearsay and, therefore, inadmissible. (People v. Carpenter (1963), 28 Ill. 2d 116, 121.) The distinction between admissible testimony and inadmissible hearsay is illustrated by the \"example of the witness A testifying that 'B told me that event X occurred.\u2019 If A\u2019s testimony is offered for the purpose of establishing that B said this, it is clearly admissible \u2014 if offered to prove that event X occurred, it is clearly inadmissible.\u201d Carpenter, 28 Ill. 2d at 121.\nThe record in the present case shows that defendants did not offer the testimony of Drs. Payne, Gianopoulos, and Hefti to establish that the event, i.e., the substance of the conversation between Drs. Tierney and Hefti, occurred. Bather, defendants offered the testimony to establish what those residents did and why they acted as they did. This evidence was to be additional circumstantial evidence to support defendants\u2019 hypothetical question to Dr. Balasaraswathi. When an out-of-court statement is used not as evidence of the fact asserted, but as circumstantial evidence for another purpose, the hearsay rule does not apply. See Reynolds v. Alton & Southern Ry. Co. (1983), 115 Ill. App. 3d 88, 98; Smith v. Solfest (1978), 65 Ill. App. 3d 779, 782-83; Goshey v. Dunlap (1973), 16 Ill. App. 3d 29, 34.\nTrue, defendants\u2019 hypothetical question to Dr. Balasaraswathi was not supported by direct evidence of the exact exchange between Drs. Hefti and Tierney. Dr. Tierney and the decedent are dead, and Dr. Hefti does not remember. However, we conclude that the hypothetical question was connected up to sufficient circumstantial evidence of record and reasonable inferences from the direct and circumstantial evidence, including the proffered testimony of the Loyola residents. After carefully reviewing the entire record, we cannot say that the trial court clearly abused its discretion in refusing to strike the hypothetical question.\nII. Sole Proximate Cause Instruction\nIn a related contention, plaintiffs claim that the trial court erred by tendering to the jury an instruction on sole proximate cause. A litigant has the right to have the jury clearly and fairly instructed upon each theory which was supported by the evidence. (Ervin v. Sears, Roebuck & Co. (1976), 65 Ill. 2d 140, 145.) However, it is error to give an instruction not based on the evidence. (See Black v. Peoria Marine Construction Co. (1987), 160 Ill. App. 3d 357, 365; Jensen v. Chicago & Western Indiana R.R. Co. (1981), 94 Ill. App. 3d 915, 929.) The question of what issues have been raised by the evidence is within the discretion of the trial court. The evidence may be slight; a reviewing court may not reweigh it or determine if it should lead to a particular conclusion. (See Burge v. Morton (1981), 99 Ill. App. 3d 266, 269.) The test in determining the propriety of tendered instructions is whether the jury was fairly, fully, and comprehensively informed as to the relevant principles, considering the instructions in their entirety. Saunders v. Schultz (1960), 20 Ill. 2d 301, 314.\nThe trial court tendered to the jury the long version of Illinois Pattern Jury Instructions, Civil, No. 12.04 (3d ed. 1989) (hereinafter IPI Civil 3d No. 12.04):\n\"More than one person may be to blame for causing an injury. If you decide that a [the] defendants] was [were] negligent and that his [their] negligence was a proximate cause of injury to the plaintiff, it is not a defense that some third person who is not a party to the suit may also have been to blame.\n[However, if you decide that the sole proximate cause of injury to the plaintiff was the conduct of some person other than the defendant, then your verdict should be for the defendant.]\u201d\nPlaintiffs contend the trial court erred in tendering the second paragraph \u00f3f this instruction for two reasons. Plaintiffs first argue that defendants did not plead the sole proximate cause of Dr. Tierney as an affirmative defense.\nWe cannot accept this argument. As we held previously, a defendant need not plead the sole proximate cause of another as an affirmative defense; rather, a general denial of any proximate cause is sufficient for the defendant to raise the defense. A defendant has the right not only to rebut evidence tending to show that defendant\u2019s acts are negligent and the proximate cause of claimed injuries, but also has the right to endeavor to establish by competent evidence that the conduct of a third person, or some other causative factor, is the sole proximate cause of plaintiff\u2019s injuries. Further, if the evidence is sufficient, the defendant is entitled to an instruction on this theory. See French v. City of Springfield (1972), 5 Ill. App. 3d 368, 374.\nPlaintiffs also argue that the record contained no evidence that supports the second paragraph of IPI Civil 3d No. 12.04. We cannot accept this argument. The notes to the instruction state: \"The second paragraph should be used only where there is evidence tending to show that the sole proximate cause of the occurrence was the conduct of a third person.\u201d (IPI Civil 3d No. 12.04, Notes on Use, at 12\u20149.) \"Whether the jury would have been persuaded is not the question. All that is required to justify the giving of an instruction is that there be some evidence in the record to justify the theory of the instruction.\u201d Lowe v. Norfolk & Western Ry. Co. (1984), 124 Ill. App. 3d 80, 118.\nAt the jury instruction conference, the trial court found that the record contained sufficient evidence of Dr. Tierney\u2019s involvement to justify giving the second paragraph of the instruction. We cannot say that the court abused its discretion. After carefully reviewing the instructions in their entirety, we conclude that the jury was fairly, fully, and comprehensively informed as to the relevant legal principles.\nIII. Defendants\u2019 Cross-Examination of Plaintiffs\u2019 Experts\nPlaintiffs next contend that the trial court erred by permitting defendants to improperly cross-examine plaintiffs\u2019 two medical experts, Drs. Kwaan and Ronald Wender. Plaintiffs contend that defendants\u2019 cross-examination: (A) violated Illinois Supreme Court Rule 220(d), and (B) was generally improper. We note that the scope of cross-examination rests within the sound discretion of the trial court and will not be disturbed on appeal absent abuse of that discretion. Sweeney v. Matthews (1970), 46 Ill. 2d 64, 71.\nPrior to trial, the parties conducted discovery of experts pursuant to Illinois Supreme Court Rule 220 (134 Ill. 2d R. 220 (repealed effective January 1, 1996)). Plaintiffs, in their answers to defendants\u2019 supplemental interrogatories, disclosed Dr. Wender as an expert witness, who would opine that defendants deviated from the applicable standard of care in several respects.\nAt trial, on direct examination, Dr. Wender\u2019s testimony did not exceed plaintiffs\u2019 responses in the Rule 220 interrogatories. He did not offer any opinions on whether defendants\u2019 alleged deviations proximately caused decedent\u2019s death. However, on cross-examination, the trial court allowed defense counsel to question Dr. Wender on the issue of proximate cause. Also, defendants cross-examined Dr. Kwaan regarding a portion of Dr. Wender\u2019s pretrial deposition, in which Dr. Wender opined that he was not sure that decedent had a pulmonary embolism.\nA. Rule 220\nRule 220(d) states:\n\"Scope of Testimony. To the extent that the facts known or opinions held by an expert have been developed in discovery proceedings through interrogatories, depositions or requests to produce, his direct testimony at trial may not be inconsistent with or go beyond the fair scope of the facts known or opinions disclosed in such discovery proceedings. However, he shall not be prevented from testifying as to facts or opinions on matters regarding which inquiry was not made in the discovery proceedings.\u201d 134 Ill. 2d R. 220(d) (repealed effective January 1, 1996).\nOn appeal, plaintiffs contend that defendants\u2019 cross-examination of Drs. Wender and Kwaan violated Rule 220(d). Plaintiffs contend that they disclosed in their answers to defendants\u2019 Rule 220 interrogatories what Dr. Wender would testify to at trial. Plaintiffs argue that defendants\u2019 cross-examination of Dr. Wender on the issue of proximate cause, and defendants\u2019 cross-examination of Dr. Kwaan regarding Dr. Wender\u2019s deposition testimony on the subject of decedent\u2019s pulmonary embolism, exceeded the scope of Dr. Wender\u2019s disclosed opinions.\nWe cannot accept this contention. Rule 220(d) expressly limits only the expert\u2019s \"direct testimony\u201d at trial to the expert\u2019s responses during discovery. We agree with the appellate court in Chiricosta v. WinthropBreon (1994), 263 Ill. App. 3d 132, that Rule 220 is a limitation on the party calling the expert as a witness. The rule should not be read \"to mean that the opposing party would be restricted from asking questions which were otherwise relevant because an expert witness had limited his answers to interrogatories or whose discovery deposition might have been limited.\u201d 263 Ill. App. 3d at 156.\nThe plain language of Rule 220(d) accords with an important purpose of discovery generally \u2014 to allow an opposing party to effectively cross-examine an expert witness. \"The principal safeguard against errant expert testimony is cross-examination.\u201d (Sears v. Rutishauser (1984), 102 Ill. 2d 402, 407.) Effective cross-examination of an expert witness requires advance preparation. The lawyer, even with the help of the lawyer\u2019s own experts, frequently cannot anticipate the particular approach the adversary\u2019s expert will take or the data on which the expert will base an opinion at trial. (28 U.S.C.A., Fed. R. Civ. P. 26(b)(4), Advisory Committee Note, 1970 Amendment, at 29 (West 1992); Graham, Discovery of Experts Under Rule 26(b)(4) of the Federal Rules of Civil Procedure: Part One, An Analytical Study, 1976 U. Ill. L.F. 895, 897.) Similarly, the purpose of our Rule 220(d) \"is to permit litigants to ascertain and rely upon the opinions of experts retained by their adversaries.\u201d (Emphasis added.) (134 Ill. 2d R. 220(d), Committee Comments, at 182.) Applying the restraints of Rule 220(d) to the party cross-examining an adversary\u2019s expert witness would thwart this recognized purpose.\nIn any event, Rule 220(d) plainly states also that the expert may testify at trial as to facts or opinions on matters that the expert was not asked during discovery. In the present case, Dr. Wender was not questioned during discovery regarding proximate cause. Thus, his testimony on the issue did not violate Rule 220. See Fogarty v. Parichy Roofing Co. (1988), 175 Ill. App. 3d 530, 541; Crawford County State Bank v. Grady (1987), 161 Ill. App. 3d 332, 340.\nWe also note that defendants\u2019 cross-examination of Dr. Kwaan regarding Dr. Wender\u2019s deposition did not violate Rule 220(d). True, plaintiffs did not disclose in their answers to defendants\u2019 Rule 220 interrogatories that Dr. Wender would offer an opinion on whether decedent had a pulmonary embolism. However, Dr. Wender testified on the subject in a pretrial deposition. Rule 220(d) specifically includes depositions in referring to discovery proceedings; \"discovery\u201d is not limited to answers to interrogatories. Defendants\u2019 cross-examination of Dr. Kwaan regarding Dr. Wender\u2019s deposition testimony on the subject of decedent\u2019s pulmonary embolism did not exceed the scope of Dr. Wender\u2019s opinion disclosed during discovery.\nB. Improper Cross-Examination\nIn addition to their contentions based on Rule 220, plaintiffs contend that defendants\u2019 cross-examination of Drs. Kwaan and Wender was improper.\nPlaintiffs contend that defendants could not cross-examine Dr. Kwaan regarding Dr. Wender\u2019s deposition testimony. We disagree. Dr. Kwaan testified that he had read Dr. Wender\u2019s deposition. It is not error to permit an expert to testify regarding reports or medical tests performed by other doctors, which the expert examined in reaching his or her own opinion. (See Piano v. Davison (1987), 157 Ill. App. 3d 649, 672.) \"Similarly the expert may be cross-examined with respect to material reviewed by the expert but upon which the expert does not rely.\u201d (1 J. Strong, McCormick on Evidence \u00a7 13, at 56-57 (4th ed. 1992).) Accordingly, we agree with the appellate court that it was not error for defendants to cross-examine Dr. Kwaan regarding Dr. Wender\u2019s deposition.\nPlaintiffs also contend that defendants\u2019 cross-examination of Dr. Wender on the issue of proximate cause was improper because it exceeded the scope of his direct testimony. As the appellate court observed, cross-examination is generally limited to the scope of the direct examination. However, circumstances resting within the witness\u2019 knowledge may be developed on cross-examination that explain, qualify, discredit, or destroy the witness\u2019 direct testimony, even though that material may not have been raised on direct examination. People v. Franklin (1990), 135 Ill. 2d 78, 97.\nIn the present case, Dr. Wender opined on direct examination that defendants had deviated from the standard of care. On cross-examination, defendants asked Dr. Wender whether those deviations proximately caused decedent\u2019s injuries. As stated earlier, proximate cause was an essential element of plaintiffs\u2019 case, which they were required to establish through expert testimony. (See Borowski v. Von Solbrig (1975), 60 Ill. 2d 418, 423.) Without that element, there would be no case. Defendants sought an answer from Dr. Wender that would explain, qualify, discredit, or destroy his direct testimony. We agree with the appellate court that it was not improper for defendants to ask the question. After carefully reviewing the record, we cannot say that the trial court abused its discretion in permitting defendants\u2019 cross-examination of Drs. Kwaan and Wender.\nIV. Manifest Weight of the Evidence\nPlaintiffs lastly contend that the jury\u2019s verdict for defendants was against the manifest weight of the evidence. Plaintiffs do not attack the weight of the evidence. Rather, citing the alleged errors raised on appeal, plaintiffs argue that the trial was \"tainted,\u201d which resulted in an \"arbitrary\u201d verdict. Consequently, they ask this court to reverse the judgment and remand the cause for a new trial.\nA judgment is against the manifest weight of the evidence only when an opposite conclusion is apparent, or when the findings appear to be unreasonable, arbitrary, or not based on evidence. (Bazydlo v. Volant (1995), 164 Ill. 2d 207, 215.) After carefully reviewing the entire record, we cannot say that the jury\u2019s verdict for defendants was against the manifest weight of the evidence.\nFor the foregoing reasons, the judgment of the appellate court is affirmed.\nAffirmed.", "type": "majority", "author": "JUSTICE FREEMAN" }, { "text": "JUSTICE McMORROW\ndissented from the denial of rehearing.", "type": "dissent", "author": "JUSTICE McMORROW" } ], "attorneys": [ "Power, Rogers & Smith, P.C., of Chicago (Joseph A.
