delivered the opinion of the court:
Roger Davis was injured when the semitractor he was driving collided with a pickup truck and rolled over. He brought a products liability action against International Harvester Company (Harvester), the manufacturer of the semitractor, alleging that the vehicle’s faulty design caused his injuries. Davis’ wife, Sharon, also filed a claim against Harvester, for loss of consortium.
Davis’ claim alleged that when the pickup truck struck his semi-tractor, it punched a hole through the tractor’s poorly supported left front comer, dislodging a vent box and forcing the vent’s sharp edges into Davis’ leg. Just prior to trial, Harvester amended its answer to include Davis’ execution of a general release as an affirmative defense and then moved for summary judgment based on the release. After a hearing, the trial court denied defendant’s motion. A jury subsequently returned a verdict for Harvester.
On appeal, Davis argues that: (1) the trial court erred in denying his motion for a new trial, which was based on his discovery, after trial, that two jurors gave false answers during voir dire; (2) the court erred in excluding evidence that Harvester had subsequently changed its semitractor design; (3) the court erred in directing a verdict for defendant on plaintiff’s claim for punitive damages; and (4) numerous other errors prejudiced his case. Harvester filed a cross-appeal in which it alleges that the court erred in denying its motion for summary judgment. We affirm the judgment for defendant.
Although not raised by plaintiffs, we must initially determine whether defendant has standing to cross-appeal. (See, e.g., Boles Trucking, Inc. v. O’Connor (1985),
I
Plaintiffs first contention on appeal is that two jurors misrepresented themselves during voir dire and that their presence on the jury was so prejudicial to him as to warrant a new trial. He claims that the trial court erred in denying his motion for a new trial and in refusing to permit him to subpoena jurors for an evidentiary hearing on the issue.
Jurors Dodge and Darnell were among a panel of 12 prospective jurors who were asked by the trial court whether they had ever “been sued or sued anyone.” Dodge replied that he had been sued in small claims court regarding some defects in a house he had sold. Another prospective juror replied that her husband had sued someone. The remaining prospective jurors, including Darnell, remained silent. In addition, when questioned individually, Darnell testified that she was married and had been married for 37 years. Plaintiff contends that Dodge failed to reveal his involvement in two other prior lawsuits— one in which he was sued by an attorney for fees, and one in which he was sued for divorce — and that Darnell failed to reveal that she had been divorced. Plaintiff raised his objections to Dodge for the first time in a supplement to his post-trial motion nearly two months after the original post-trial motion was filed. He raised his objection to Darnell over three months later, in an additional supplement to his post-trial motion. Harvester contends that plaintiff has waived this issue by failing to investigate diligently the prospective jurors prior to trial, or at least prior to filing his post-trial motion.
In Pekelder v. Edgewater Automotive Co. (1977),
We conclude that plaintiff has not demonstrated that he was prejudiced by the jurors’ omissions. With respect to Darnell, plaintiff’s allegations do not establish that she lied. She was not asked whether she had ever been divorced, and the fact that she had been divorced does not establish that she was not then married or that she had not been married for 37 years.
It is clear, though, that both jurors failed to reveal their involvement in certain prior lawsuits. It is equally clear from the responses of all of the prospective jurors, however, that the attorneys must have realized that the trial court’s general question regarding prior lawsuits was inadequate. Jurors Willis and Smith, who were also among those remaining silent after the court’s general question, revealed involvement in prior lawsuits upon more specific questioning by the attorneys. Another prospective juror, Juror Shadden, replied “no” to plaintiff’s attorney’s direct question whether he or any member of his family had been involved in any kind of lawsuit. When the attorney subsequently asked him whether he had ever used a lawyer, however, Shadden replied that he had used one in connection with his divorce. Shadden additionally stated that he had not been satisfied with the way the court system had operated in his case, but that his experience would not affect his judgment in plaintiff’s case. Plaintiff’s attorney apparently did not consider either Shadden’s divorce experience or his omission important, because both parties accepted him as a juror. We may fairly conclude, therefore, that the attorney would have reacted similarly to the divorce experiences of Dodge and Darnell had they been revealed. In addition, both jurors revealed prior litigation experience (Dodge as a litigant and Darnell as a juror) and each stated that those experiences would not affect his or her judgment in plaintiff’s case. We conclude that the additional information gained about the jurors does not indicate that they were biased against either party and does not negate plaintiff’s earlier conclusion that they were impartial. See Kingston v. Turner (1987),
We also do not believe the court erred in refusing to permit plaintiff to subpoena the jurors for an evidentiary hearing. This court has held that a hearing is necessary where there is no record of the voir dire available and subsequently discovered information indicates that one or more of the jurors may have been directly prejudiced against one of the parties. (Schulz v. Rockwell Manufacturing Co. (1982),
We summarily reject plaintiff’s contention that the jurors’ false answers violated his statutory right to challenge them for cause. (See Ill. Rev. Stat. 1985, ch. 78, par. 14.) A juror’s involvement in prior, unrelated litigation is not enough to establish even the suspicion of bias or partiality. And even if it were established, a suspicion of bias is insufficient to disqualify a juror for cause. People v. Cole (1973),
We also find merit in Harvester’s contention that plaintiff waived this issue by waiting until after the verdict to investigate the prospective jurors. Plaintiff discovered the jurors’ involvement in prior suits long after trial, by investigating public records which were available to him during the voir dire and over the course of the trial. While we do not hold that no challenge may be made to jurors after trial based on information which might have been discovered prior to or during trial (see, e.g., Schulz v. Rockwell Manufacturing Co. (1982),
II
Plaintiff next contends that the trial court erred in refusing to allow testimony regarding a subsequent design change by Harvester. Plaintiff sought to introduce evidence that Harvester altered the design of its semitractor cabs in 1981 and that the new model had no vent opening on the driver’s side of the cab. The court excluded the evidence when Harvester stipulated that the air vent of its model 4070-B semitractor cab (the model which plaintiff was driving) “could have been feasibly placed in areas other than the front left cab.” Plaintiff contends that evidence of the post-occurrence change was admissible notwithstanding the stipulation.
As a general rule, evidence of subsequent remedial measures is not admissible to prove negligence or culpable conduct. (See Hodges v. Percival (1890),
Plaintiff argues that the rule should not be applied in products liability actions, in which the focus is on the condition of the product rather than the conduct of the defendant. We note that the Illinois rule is comparable to Rule 407 of the Federal Rules of Evidence, which the Federal Court of Appeals has overwhelmingly found applicable to products liability actions notwithstanding similar arguments against its use. (See Gauthier v. AMF, Inc. (9th Cir. 1986),
Illinois courts permit evidence of subsequent remedial measures to be used for other purposes, however, such as to show the feasibility of precautionary measures. (See E. Cleary & M. Graham, Handbook of Illinois Evidence §407.1, at 182-83 (4th ed. 1984); see also Gauthier,
The Sutkowski holding was either misconstrued or summarily expanded by the Appellate Court for the First District in Burke v. Illinois Power Co. (1978),
Plaintiff correctly asserts that Holmes v. Sahara Coal Co. (1985),
Plaintiff next argues that, even if the evidence was admissible only on the issue of feasibility, the court erred in excluding evidence of the actual design changes based solely on Harvester’s bland admission that it would have been feasible to place the vent elsewhere. (Cf. 73 Am. Jur. 2d Stipulations §§1, 15 (1974) (noting that some stipulations are actually admissions rather than agreements).) Dean Wigmore stated that a trial court may exclude evidence on an issue which has been judicially admitted because: (1) the evidence is no longer relevant to the issues remaining in the case; (2) the evidence may be superfluous and confusing; and (3) the other party may not necessarily be entitled to the additional dramatic force of the evidence (which the admission is, in fact, frequently designed to obviate). (9 Wigmore, Evidence §2591, at 824 (Chadbourn rev. ed. 1981).) Wig-more concluded, however, that, because “a colorless admission *** may sometimes have the effect of depriving the party of the legitimate moral force of his evidence,” there should be no absolute rule and the admission or exclusion of additional evidence should be left to the trial court’s discretion. (Emphasis in original.) 9 Wigmore, Evidence §2591, at 824-25 (Chadbourn rev. ed. 1981); see also 75 Am. Jur. 2d Trial §133 (1974) (concluding that the matter rests in the discretion of the trial judge); cf. People v. Munday (1920),
Had the trial court admitted the evidence in the instant case, it would have risked the jury’s drawing the improper inference that Harvester changed its design because it recognized that its product was dangerously defective. In addition, the evidence was not critical to plaintiff on the issue of feasible alternative designs. In addition to Harvester’s stipulation, the testimony of plaintiff’s expert witnesses established that most other semitractor manufacturers did not place vent openings on the driver’s side of their cabs. The potential unfair prejudice to Harvester therefore substantially outweighed the probative value of the evidence. (See E. Cleary & M. Graham, Handbook of Illinois Evidence §403.1, at 149-50 (4th ed. 1984) (regarding the appropriate standard for excluding prejudicial evidence).) There was, in fact, no genuine dispute regarding the feasibility of alternative designs. (See Coshenet v. Holub (1980),
We additionally reject plaintiff’s related contention that the trial court erred in excluding photographic evidence of tractors designed by other manufacturers which had no vent on the driver’s side of the cab. The evidence would merely have been cumulative of testimony by plaintiff’s expert that he was able to find only one other manufacturer who placed a vent in that area. The extent to which a party may present evidence on a particular issue is largely within the discretion of the trial court. (See People v. Williams (1983),
Nor do we find any error in the court’s exclusion of 82 photographs of damaged trucks which plaintiff offered to demonstrate a propensity of the vent area to crack on impact. Evidence of prior accidents is admissible to demonstrate that a vehicle is dangerous if the proponent establishes that the accidents occurred in a substantially similar manner. (Rucker v. Norfolk & Western Ry. Co. (1979),
Ill
Plaintiff next contends that the trial court erred in directing a verdict for defendant on his punitive damages claim for willful and wanton conduct by Harvester. In light of the jury’s verdict in favor of Harvester, which we here affirm, any error in directing a verdict for defendant on these counts must be deemed harmless. (See Ritter v. Ferenczi (1973),
“The question of willful and wanton conduct is essentially whether the failure to exercise care is so gross that it shows a lack of regard for the safety of others.” (Moore v. Jewel Tea Co. (1969),
Plaintiff failed to produce evidence that Harvester was aware of the dangerous condition in its semitractor cab. There was no evidence produced that Harvester had received complaints of similar accidents or injuries, and the conclusion by plaintiff’s expert that the vehicle was unreasonably dangerous did not establish that Harvester knew or should have known that the vehicle was defective and likely to cause injury. See, e.g., Moore v. Remington Arms Co. (1981),
Nor can we accept plaintiff’s contention that he was denied the opportunity to establish Harvester’s willful and wanton onduct through evidence of a post-occurrence change. In Collins v. Interroyal Corp. (1984),
IV
Plaintiff alleges numerous additional errors by the trial court, each of which we will address only briefly.
Plaintiff contends that the trial court erred in requiring one of his experts to answer a hypothetical question regarding safety features which might have prevented plaintiff’s injury, rather than permitting him to render an opinion based on facts not in evidence. An expert may ordinarily state an opinion without first disclosing the facts or data on which it is based. (Wilson v. Clark (1981),
We similarly conclude that no prejudice could have resulted to plaintiff from the court’s refusal to allow another of plaintiff’s experts to testify regarding statistical data on which he based his opinion. An expert may disclose facts or data not in evidence on which his opinion is based. (See E. Cleary & M. Graham, Handbook of Illinois Evidence §705.1, at 493 (4th ed. 1984).) Plaintiff’s expert was permitted to render his opinion that the impact to the cab of plaintiff’s semi-tractor was foreseeable, because any vehicle the size of a pickup truck or larger would be large enough to impact with the cab in a collision. He also stated that those vehicles make up a certain portion of all highway traffic. He was not permitted to refer to the Department of Transportation statistics from which he determined the percentages of highway vehicles falling into that category or to state what those percentages were. We cannot conclude that the mere omission of those percentages was prejudicial to plaintiff’s case.
Plaintiff next contends that the trial court erred in refusing to permit his witness, Harold Dietz, to state his opinion that plaintiff’s vehicle was unsafe. Dietz was an occurrence witness and an experienced truck driver. A trial court has broad discretion in determining whether a witness is qualified to render an expert opinion. (People v. Park (1978),
Plaintiff next argues that Harvester violated several of its discovery requests. Pursuant to Supreme Court Rule 237 (107 Ill. 2d R. 237), plaintiff requested that Harvester produce one of its engineers, Michael Shirley, to appear as a witness at trial and produce all reports, memoranda, or other materials relied upon by him. Shirley was called as a witness by both plaintiff and defendant. During cross-examination, plaintiff’s counsel asked Shirley whether he had corresponded with another of Harvester’s expert witnesses, Russell Noble. Shirley responded that he had, whereupon plaintiff’s counsel stated, “You were asked to produce that, and I never saw any of that.” The court then spoke with the attorneys outside the jury’s presence. Defendant’s counsel objected to plaintiff’s counsel’s implication, in front of the jury, that Harvester failed to produce requested materials. He stated that if plaintiff had requested correspondence he would have received it. The court sustained defendant’s objection and noted that plaintiff’s production request applied only to materials the expert had relied upon in forming his opinion. Plaintiff does not argue that Shirley relied on the letters, and we therefore cannot conclude that Harvester violated the request. Plaintiff argues on appeal that he also requested by letter that Shirley produce his entire file. However, plaintiff’s attorney made that same representation to the trial court and informed the court that he would produce the letter at a later time. He did not do so. We therefore conclude that plaintiff has waived the alleged discovery violation. See Varady v. Guardian Co. (1987),
We find that plaintiff also waived any alleged violation of his discovery request regarding the production of an article written by Mr. Noble. Harvester’s counsel supplied plaintiff with one article that Noble had written and informed the court that he had complied with its order to contact the Society of Automotive Engineers, which apparently published the second article, but that the Society had been unable to locate it. Plaintiff made no further objections or requests for sanctions and therefore waived the alleged violation. See Varady,
We summarily reject plaintiff’s contention that he was not permitted to examine Mr. Noble regarding a conversation he had with Mr. Shirley. The record indicates that the only restriction placed on plaintiff’s counsel was that he ask specific questions, rather than asking Noble to relate a two-hour conversation.
Plaintiff next contends that the court erred in refusing to give several of its jury instructions. We disagree. Plaintiff’s instruction No. 20 (Illinois Pattern Jury Instructions, Civil, No. 400.10 (2d ed. Supp. 1986) (IPI Civil 2d)), relating to the defendant’s exercise of due care, was properly refused because defendant did not produce evidence of due care in the manufacture or inspection of its product, but claimed, as stated in Plaintiff’s instruction No. 16, that the product was not unreasonably dangerous and had not caused plaintiff’s injuries. (See Jensen v. Chicago & Western Indiana R.R. Co. (1981),
We additionally find that the court did not err in giving Defendant’s instructions No. 10 and No. 10A (IPI Civil 2d No. 400.01). While the instructions were repetitious, they were neither misstatements of the law nor prejudicial to plaintiff. See Pease v. Ace Hardware Home Center (1986),
Plaintiff has cited no relevant authority in support of his remaining contentions in violation of Supreme Court Rule 341(eX7). (107 Ill. 2d R. 341(eX7).) We therefore deem those issues waived and will not address them. People v. Ramirez (1983),
For the reasons stated above, the cross-appeal is dismissed, and the judgment of the circuit court is affirmed.
Cross-appeal dismissed; judgment affirmed.
