delivered the opinion of the court:
Defendants E. Reimer and Copley Memorial Hospital (Copley) (Ann West is not involved in this appeal) appeal an order of the circuit court of Kane County denying their motion to dismiss brought pursuant to section 2 — 619 of the Civil Practice Law (735 ILCS 5/2 — 619 (West 2000)). In their motion, defendants contended, inter alia, that plaintiffs present action is barred by res judicata. The trial court disagreed. Defendants then requested the trial court to make the necessary findings under Supreme Court Rule 308 (155 Ill. 2d R. 308) that would allow an interlocutory appeal. This request was granted and the trial court certified the following question for review: “[UJnder the doctrine of res judicata, is there an identity of cause of action in plaintiffs’ [sic] prior and present suits[?]” We answer this question in the affirmative.
BACKGROUND
Plaintiff, Lindsey Cload, by her mother and next friend, Gina Cload, instituted an action against Dr. Ann West, Dr. Philip Jacobsen, and Copley in the circuit court of Cook County on March 3, 1995. The complaint sounded in malpractice and concerned events related to the birth of Lindsey. Lindsey was born on June 13, 1991. Gina began experiencing labor pains that morning and was admitted to Copley at approximately 10 a.m. She was placed under the care of West, an obstetrician. At approximately 5:15 p.m., Lindsey was delivered. Lindsey was born with significant brain injuries and suffers from cerebral palsy.
Lindsey contends that her injuries were a result of the negligence of various individuals involved in her birth. In an earlier action to which Gina was also a party, Lindsey and Gina set forth a four-count complaint. Count I named Lindsey as the plaintiff and alleged three omissions by West and Jacobsen. First, it stated that the doctors failed to order a caesarian section despite evidence of fetal distress. Second, it alleged that they failed to perform a caesarian section despite evidence of fetal distress. Third, it asserted that they failed to conduct tests necessary to diagnose Lindsey’s condition. Count II was also brought in Lindsey’s name and identified Copley as the defendant. In this count, it was alleged that Copley, through its servants and agents, failed to promptly notify the doctors of evidence of fetal distress and failed to perform appropriate tests to diagnose Lindsey’s condition. Count III and count IV repeated the allegations contained in the first two counts; however, Gina was named as the plaintiff.
Copley moved for summary judgment on the first complaint. Copley argued that
On July 24, 2000, an amended complaint was filed. Lindsey was listed as the sole plaintiff. As defendants, the complaint identified West, Copley, and Reimer, who was a Copley employee. The complaint contained two counts. Count I was directed against West and was based on several omissions. First, it again alleged that West failed to order a caesarian section despite evidence of fetal distress. Second, it again asserted that West failed to perform a caesarian section despite evidence of fetal distress. Third, it repeated the allegation that West failed to conduct tests necessary to diagnose Lindsey’s condition. Fourth, it alleged that West failed to take appropriate steps to clear Lindsey’s airway “following delivery.” Fifth, it maintained that West failed to have appropriate personnel present to attend to Lindsey “immediately following delivery.” Finally, it stated that West was otherwise careless and negligent.
The second count of the amended complaint was directed against Copley and Reimer. This count was based on several acts or omissions occurring “upon the delivery” of plaintiff. First, it asserted that defendants failed to properly resuscitate Lindsey. Second, it alleged that defendants failed to promptly and adequately suction meconium from Lindsey’s airways. Third, it maintained that defendants failed to promptly intubate Lindsey. Fourth, it alleged defendants failed to properly monitor and support Lindsey’s respiration. Fifth, it stated that defendants were otherwise careless and negligent.
Defendants moved to dismiss plaintiffs amended complaint, arguing that the current action was barred by res judicata. The trial court denied defendants’ motion. The court observed that the first two elements necessary to invoke the doctrine — a final judgment on the merits and identity of parties — were indisputably met. However, the court concluded that the final element, identity of cause of action, was lacking. The court first acknowledged our supreme court’s decision in River Park, Inc. v. City of Highland Park,
ANALYSIS
This case comes to us following the trial court’s denial of a motion to dismiss made pursuant to section 2 — 619 of the Civil Practice Law (735 ILCS 5/2 — 619 (West 2000)); therefore, review is de novo. McGee v. State Farm Fire & Casualty Co.,
The sole issue before us is whether the trial court correctly determined that res judicata is inapplicable because no identity of cause of action exists between plaintiff’s prior and present claims. Res judicata precludes subsequent litigation between the same parties on a claim after a court renders final judgment on a matter. Torcasso v. Standard Outdoor Sales, Inc.,
Our supreme court has adopted the transactional test for determining whether causes of action are the same. River Park, Inc.,
Prior to River Park, Inc., Illinois employed both the same-evidence test and the transactional test. Under the same-evidence approach, claims were deemed part of the same cause of action if “the evidence needed to sustain the second suit would have sustained the first, or if the same facts were essential to maintain both actions.” Rodgers v. St. Mary’s Hospital,
Despite the supreme court’s rejection of the same-evidence test, the evidence necessary
In determining whether claims are part of the same cause of action, River Park, Inc. directs that we consider the claims in factual rather than evidentiary terms. River Park, Inc.,
Turning to the present appeal, it is clear that the claims asserted in the instant case and the claims asserted in the previous case arise from a single group of operative facts. First, they share a close temporal relationship. In the earlier action, plaintiffs allegations were based upon events connected with Lindsey’s labor and delivery, while in the present case plaintiff alleges omissions that occurred “upon the delivery” of plaintiff. Moreover, in her allegations against West, plaintiff points to the failure to clear her airway “following delivery” and the failure to have appropriate personnel present “immediately following delivery.” Labor, delivery, and immediate postpartum care are a continuous series of events. Cf. Figueroa v. Illinois Masonic Medical Center,
Similarly, the spatial relationship between the events indicates that they are part of a single transaction. Count I of the amended complaint alleges that West failed to have “appropriate personnel present to attend to the plaintiff *** immediately following delivery.” An affidavit of a doctor, submitted in support of the amended complaint, also states that a neonatologist should have been present at the time of delivery. These two references to having specialists present indicate that the events following delivery occurred in the same place as those preceding delivery. Hence, the events alleged in both complaints were intimately linked in a spatial sense.
The origin of the events alleged in the two complaints provides a further link.
The events that constitute the basis of this suit form a convenient trial unit. Implicitly conceding that such a relationship exists, in her amended complaint plaintiff has persisted in her allegations against West regarding West’s failure to order or perform a caesarian section. As to the parties’ expectations, we find little evidence. However, given the close spatial and temporal relationship between the events alleged, the link in their origin and motivation, and the fact that plaintiff alleged events occurring both before and after delivery in her amended complaint, it is difficult to conceive of how their treatment as a unit could be contrary to the parties’ expectations.
The final factor we must consider is whether the treatment of the events as a unit conforms to business understanding or usage. The amended complaint posits a duty on West’s part concerning events occurring both before and after delivery. These allegations suggest that the same medical professional was in charge of events occurring both before and after delivery. This in turn implies that, from the standpoint of the medical community, the events occurring before delivery are a part of the same occurrence as events occurring after delivery. Moreover, the affidavit of the doctor that plaintiff submitted in support of her ajnended complaint states that Lindsey exhibited stress in útero, which made it foreseeable that she would need supportive care at birth, including clearing meconium from her airways and providing respiratory assistance. Thus, a single medical professional provided an analysis of events occurring prior to delivery and their implications for the type of postdelivery care that should have been provided. Since one medical professional was able to make such an evaluation, it is apparent that both predelivery and postdelivery care fall within the same field of medical expertise. Again, from the standpoint of the medical community, these events are linked.
All of the factors set forth in River Park, Inc. (see River Park, Inc.,
In denying defendants’ motion, the trial court observed that “[i]n River Park, the court noted that the parallels between the factual allegations of the complaints in the state and federal claims were a most telling indication of identity of cause of action.” While such parallels did exist in River Park, Inc., we do not believe that the supreme court intended to set forth a test whereby one simply compares the particular allegations in various complaints to see if they coincide. Such a test would not differ significantly from the same-evidence test. Rather, River Park, Inc. contemplates an analysis of the relationship between the factual allegations in the complaints at issue, where, as noted above, considerations such as their temporal and spatial proximity are relevant. See River Park, Inc.,
We also find it of no moment that plaintiff’s current complaint names Reimer as a defendant while her former complaint did not. The allegations against Reimer concern conduct that we have already concluded is part of the same transaction as that alleged in the previous complaint. We note that plaintiff does not contest that Reimer was either a party or in privity with a party to plaintiffs first complaint. Plaintiff cannot avoid the effect of res judicata simply by explicitly naming one of Copley’s employees.
Plaintiff also points out that in some circumstances res judicata may be relaxed where justice requires. The doctrine will not be applied where it would be fundamentally unfair to do so. Weisman v. Schiller, Ducanto & Fleck,
Plaintiff contends that it is the policy of this state to protect the rights of disabled persons and children and that we should consequently apply a relaxed standard in determining if her present action is barred. It is true that Illinois law protects the rights of disabled persons and children in various situations. See, e.g., In re Estate of Mank,
Furthermore, litigation, even when it involves a plaintiff who is a member of a favored class, must end at some point. A disabled person or minor, like anyone else, may lose a suit. If we were to accept plaintiffs policy argument, such plaintiffs, merely by virtue of their status, would be free to relitigate causes of action, at least so long as they were able to alter their legal theory of the particular facts upon which they rely. We cannot conclude that disabled persons and minors are immune from the rule against claim splitting. They, like anyone else, must assert all claims arising out of a single transaction in one suit.
CONCLUSION
In light of the foregoing, we conclude that an identity of cause of action exists between plaintiffs prior and present actions. This cause is remanded to the trial court so that it may enter an appropriate order and take any further actions as necessary.
Certified question answered; cause remanded.
BOWMAN and RAPALA, JJ., concur.
