delivered the opinion of the court:
Defendant Caroline Cogtella filed a lawsuit against defendants DePaul University (DePaul), L&L Engineers and Holabird & Root (H&R), alleging that she suffered bodily injury due to her exposure to the fluorescent lighting selected and installed in DePaul University’s Goldblatt building. DePaul tendered its defense of Cogtella’s complaint to plaintiff American Economy Insurance Co. (American Economy) because American Economy was the insurer of Metrick Electric Co. (Metrick), the electrical subcontractor that was hired to install the lighting at the Goldblatt building, and DePaul was a named additional insured on Hetrick’s insurance policy. American Economy denied coverage and filed this declaratory judgment action as to its duty to defend in the Cogtella litigation. The trial court, in considering cross-motions for summary judgment, held that American Economy had an obligation to defend DePaul in the Cogtella litigation.
American Economy appeals, arguing that the trial court erred in finding that American Economy had a duty to defend DePaul because the complaint filed by Cogtella does not allege any negligence by Hetrick and the trial court could not consider a third-party complaint filed by DePaul to find such a duty.
In December 1995, Cogtella filed her complaint for negligence, professional negligence, and negligent infliction of emotional distress against H&R, DePaul, and L&L Engineers. Cogtella’s complaint alleged the following facts.
On or about November 1, 1991, the City of Chicago (City) and DePaul entered into an agreement in which the City sold real estate known as the Goldblatt building to DePaul, and DePaul, in turn, granted the City a leasehold interest for a portion of the building for City offices. Pursuant to that agreement, the City contracted with H&R to be the architect and general contractor for the design and construction of the City’s space in the Goldblatt building. L&L Engineers was the electrical subcontractor on this project. All plans and specifications for the design and construction of the City’s space were submitted to DePaul for approval.
Cogtella alleged that H&R, DePaul, and L&L Engineers selected and installed fluorescent light fixtures and lights in the City’s space. However, they did not choose to shield or filter the lights with commercially available and reasonably priced diffusers or filters that would diffuse or reduce the ultraviolet (UV) rays emitted by the fluorescent lights to a safe level. Cogtella further claimed that, “At no time during the planning, preparation of specifications, or construction of the City’s leasehold space did Defendants consider the possible health effects on people occupying the City’s space when they decided to install fluorescent lighting in the space.”
Cogtella worked as the risk manager for the City’s department of finance, risk management office, which moved into a portion of the City’s space in the Goldblatt building. Cogtella had been previously diagnosed with lupus erythematosus, an autoimmune disease which causes inflammation of various parts of the body, especially the skin, joints, blood and kidneys. At the time Cogtella began working in the Goldblatt building, her illness was under control and did not cause any impairment in her ability to perform her job. However, within days of Cogtella’s move to the new work area in the Goldblatt building, she experienced a sudden, serious illness. She suffered severe erythema and edema of her face, neck and hands associated with first degree burns, skin lesions, hair loss, severe joint pain, vision impairment, and exhaustion. Cogtella alleged that this sudden illness was caused by her exposure to the unfiltered and undiffused fluorescent lighting in her work area.
In count I, Cogtella raised a claim of negligent infliction of emotional distress and alleged that defendants had a duty to provide a safe work area, free from hazards, for all people occupying the Goldblatt building and that they carelessly and negligently breached their duty and caused severe physical harm to Cogtella. These negligent acts and omissions proximately caused Cogtella “to suffer emotional distress of both a physical and mental nature” and she will continue to suffer “severe emotional and physical illness and financial harm.” In count IX Cogtella alleged that DePaul owed Cogtella “a duty to exercise reasonable care, skill, knowledge, and judgment in exercising its duty as landlord to ensure that the design and installation of the lighting system for the City’s leased space did not present a danger to the occupants and users of the space.” Contrary to its duty, DePaul was guilty of one or more of the following careless and negligent acts or omissions:
“a. Improperly installed the fluorescent lighting fixtures and lights without installing diffusers or filters which would reduce or eliminate harmful UV emissions from the lights;
b. Failed to reasonably educate itself about current medical and scientific information and literature relating to the dangers of exposure to UV emissions from fluorescent lights;
c. Failed to ensure that the fluorescent lighting fixtures and lights installed in the City’s leasehold space was [sic] safe;
d. Failed to advise Defendants Holabird and Root and L&L that the fluorescent lights and lighting systems presented an unreasonable danger to the people occupying the City’s leased space;
e. Was otherwise careless and negligent.”
In June 1997, DePaul filed a third-party complaint against Hetrick and the City. In count II, DePaul alleged that Hetrick “was in charge of the installation of the electrical light fixtures in [Cogtella’s] work station and on the fourth floor of the DePaul Center.” DePaul further alleged that Hetrick owed a duty to Cogtella to install electrical lighting fixtures that would not cause her physical, mental or emotional illness. DePaul claimed that Hetrick was guilty of the following careless and negligent acts and/or omissions:
“a. Failed to reasonably educate itself regarding the potential danger or harm caused by exposure to ultraviolet ray emissions from florescent lights which they installed into buildings;
b. Failed to ensure that the florescent lighting fixtures and light[s] installed in the City’s work space on the fourth floor of the DePaul Center and in [Cogtella’s] work station were safe so as not to cause physical, mental and emotion[al] illness to its workers;
c. Failed to properly consult with its lighting engineer, L&L Engineers, and its architect, Holabird & Root, in order to ensure that the florescent lights and lighting systems chosen by the City of Chicago for [Cogtella’s] work station and the fourth floor of the Goldblatt building were safe and did not present a danger to the City of Chicago employees occupying the City of Chicago’s leasehold space; and
d. Was otherwise careless and negligent.”
In March 1999, American Economy filed its complaint for declaratory judgment, asking the trial court to find that H&R 1 , DePaul, the City, and L&L Engineers did not qualify as additional insureds on Hetrick’s policy, and therefore, American Economy had no duty to defend or indemnify the defendants in connection with the Cogtella litigation.
American Economy and Hetrick entered into a contract for general liability insurance, effective October 1, 1993, to October 1, 1994. H&R, DePaul, L&L Engineers and the City were added as additional insureds under the policy pursuant to an additional insured endorsement, which provided as follows:
“WHO IS AN INSURED (Section II) is amended to include as an insured the person or organization shown in the Schedule but only with respect to liability arising out of ‘your work’ for that insured by or for you.”
The Cogtella litigation was settled in January 2000. In March 2005, the trial court denied American Economy’s motion for summary judgment and granted DePaul’s cross-motion for summary judgment. In November 2005, the trial court entered a money judgment in the amount of $179,027.55, plus interest, in favor of DePaul. This appeal followed.
The issue before us on appeal is whether American Economy has a duty to defend DePaul as an additional insured when the only allegations against the named insured, Hetrick, are in DePaul’s third-party complaint. American Economy maintains that because Cogtella did not name Hetrick in the underlying complaint or allege any negligence on Hetrick’s part, it does not have a duty to defend DePaul. DePaul responds that “the pleadings in the underlying litigation establish, at a minimum, that DePaul’s liability potentially arose out of Hetrick’s work.”
“The construction of an insurance policy and a determination of the rights and obligations thereunder are questions of law for the court which are appropriate subjects for disposition by way of summary judgment.” Crum & Forster Managers Corp. v. Resolution Trust Corp.,
The primary function of the court when construing an insurance policy is to ascertain and enforce the intentions of the parties as expressed in the agreement. Crum & Forster Managers Corp.,
“To determine an insurer’s duty to defend its insured, a court must look to the allegations of the underlying complaints. If the underlying complaints allege facts within or potentially within policy coverage, the insurer is obliged to defend its insured even if the allegations are groundless, false, or fraudulent.” Northbrook Property & Casualty Co. v. Transportation Joint Agreement,
“As the threshold for pleading a duty to defend is low, any doubt with regard to such duty is to be resolved in favor of the insured.” United Services Automobile Ass’n v. Dare,
In order to determine whether American Economy is required to defend DePaul as an additional insured, we must look at the language of the additional insured endorsement. Under the policy, American Economy is required to defend DePaul as an additional insured of Hetrick “but only with respect to liability arising out of ‘your work’ for [DePaul] by or for [Hetrick].” According to the definition in the policy,
“ ‘Your work’ means:
a. Work or operations performed by you or on your behalf; and
b. Haterials, parts or equipment furnished in connection with such work or operations.
‘Your work’ includes warranties or representations made at any time with respect to the fitness, quality, durability or performance of any of the items included in a. or b. above.”
Illinois courts have held that the phrase “arising out of’ is “both broad and vague, and must be liberally construed in favor of the insured; accordingly, ‘but for’ causation, not necessarily proximate causation, satisfies this language.” Maryland Casualty Co. v. Chicago & North Western Transportation Co.,
The underlying complaint alleged that it was the selection and the installation of fluorescent lighting without UV diffusers that caused Cogtella’s injury. Although that complaint does not mention Hetrick’s installation of the lighting, the third-party complaint filed by DePaul alleged that Hetrick “was in charge of the installation of the electrical light fixtures in [Cogtella’s] work station and on the fourth floor of the DePaul Center.” American Economy contends that this court cannot look to the third-party complaint to ascertain Hetrick’s involvement, but is limited to the allegations in the Cogtella complaint and the subject policy. Thus, we need to determine whether we may consider any evidence beyond the underlying complaint, such as the third-party complaint filed here, in order to determine the duty to defend.
In our decision in the related American Economy appeal, we engaged in a lengthy analysis of the Illinois cases in which evidence beyond the underlying complaint was admitted in determining the duty to defend. See American Economy,
Based on that authority, we held that “consideration of a third-party complaint in determining a duty to defend is in line with the general rule that a trial court may consider evidence beyond the underlying complaint if in doing so the trial court does not determine an issue critical to the underlying action (see Envirodyne,
However, there is one important factual distinction between this case and the related American Economy decision, which is that DePaul was the party that prepared and filed the third-party complaint against Hetrick and used its complaint to seek coverage from American Economy as an additional insured. American Economy relies on Lexmark International, Inc. v. Transportation Insurance Co.,
In Shriver, Shriver Insurance Agency (Shriver) filed a declaratory judgment action against its insurer, Utica Mutual Insurance Company (Utica), after Utica declined to defend Shriver in an underlying lawsuit. Utica filed a motion to dismiss Shriver’s complaint based on a policy exclusion. Shriver responded to the motion and filed a motion for summary judgment. Shriver attached an affidavit from its president as well as the letter sent to Utica informing it of the underlying action and the facts leading up to the lawsuit. Utica filed its own motion for summary judgment. The trial court granted Shriver’s motion for summary judgment and found that Utica had a duty to defend Shriver because the letter prepared by Shriver’s president constituted true but unpleaded facts known to Utica. Shriver,
On appeal, the reviewing court found that the complaint in the underlying action “alleged the type of risk Utica intended to exclude from coverage.” Shriver,
“In [La Rotunda], the court determined that Royal Globe had a duty to defend where the results of its own investigation disclosed the true but unpleaded fact that all of the land in question was not used as a junkyard or refuse dump. Therefore, smoke from the land, which caused a driving accident on a neighboring road, might have come from the vacant part of the land and not the junkyard, making the business exclusion in Royal Globe’s policy inapplicable.
In [Associated Indemnity], the insurer, Insurance Company of North America (INA), knew that unpleaded facts related to it by Associated Indemnity were true. INA possessed a file containing documents produced in the underlying litigation that verified the truth of Associated Indemnity’s facts. Also, INA knew the facts to be true because it was defending another party in the underlying action.” Shriver,323 Ill. App. 3d at 251-52 , citing La Rotunda,87 Ill. App. 3d at 452 , and Associated Indemnity,68 Ill. App. 3d at 818-19 .
Nevertheless, the Shriver court continued its analysis to find that even if the unpleaded facts were assumed to be true, the facts did not raise the possibility that the underlying lawsuit was within the coverage of Utica’s policy. Shriver,
Here, the third-party complaint alleging Hetrick’s involvement in the Goldblatt building construction was prepared by the insured, DePaul. However, even if we decline to consider DePaul’s third-party complaint, other true but unpleaded facts are present in the case that were not provided by the insured.
In the related American Economy opinion, we found that the record showed “that in addition to the third-party complaint, true but unpleaded facts should have alerted American Economy to the possibility that the Cogtella complaint against H&R was potentially within the coverage of the Hetrick policy.” American Economy,
“First, we note that American Economy has never disputed the fact that Hetrick installed the lighting. However, in its motion for summary judgment, American Economy contended that the injuries alleged in the Cogtella complaint arose from the selection of fluorescent lighting and that ‘there is no suggestion in her complaint that the manner of installation had any contribution whatsoever to her alleged injury.’ This statement is not supported by the Cogtella complaint. In her complaint, Cogtella alleged that ‘Defendants selected and installed fluorescent light fixtures and lights. However, they did not elect to shield or filter the lights with commercially available and reasonably priced diffusers or filters that would diffuse or reduce to a safe level the ultraviolet (UV) rays emitted by the fluorescent lights.’ Thus, Cogtella alleged that her injuries were caused by the selection as well as the installation of the fluorescent lighting without diffusers. Further, Metrick’s subcontract for its work at the Goldblatt building is included in the record and provides that Metrick was responsible for the construction of the ‘complete operating electrical system.’
Additionally, American Economy knew that Metrick installed the lighting and that the Cogtella lawsuit arose from the selection and installation of fluorescent lighting because it represented Metrick in the underlying case. Again, American Economy does not dispute this fact. *** Based on its representation of Metrick in the underlying lawsuit and Metrick’s subcontract, American Economy knew that Metrick installed the lighting at the Goldblatt building and that the Cogtella complaint alleged that her injuries were caused by the selection and installation of the fluorescent lighting without diffusers.” American Economy,382 Ill. App. 3d at 1034-35 .
The additional insured endorsement provided coverage for liability arising out of Metrick’s work for DePaul. As we previously stated, “arising out of” is to be liberally construed in favor of the insured and only a “but for” causation is required. See Maryland Casualty Co.,
Based on all of the foregoing, we find the trial court properly held that American Economy has a duty to defend DePaul and we affirm the decision of the circuit court of Cook County.
Affirmed.
