The Supreme Court of Illinois addressed the case Southern Illinoisan v. Illinois Department of Public Health, Docket No. 98712, filed on February 2, 2006. The plaintiff, a daily newspaper, requested data from the Illinois Department of Public Health regarding neuroblastoma incidents in Illinois from 1985 onward, asserting the information was public and should be released under the Freedom of Information Act (FOIA). The Department initially denied the request, citing exemptions under the FOIA and the Medical Studies Act, which protects information collected in medical studies. Following a series of legal proceedings, including a summary judgment in favor of the plaintiff by the circuit court and subsequent appellate court affirmations, the appellate court ultimately directed the Department to release the requested information. The Supreme Court affirmed the appellate court's judgment, underscoring the public interest in the requested data to investigate potential cancer clusters in Illinois. Plaintiff referenced the appellate court decision in *May v. Central Illinois Public Service Co.* to support a request for disclosure of documents, arguing that the Department had not asserted any statutory exemptions in its response to the FOIA request. On June 8, 2005, the plaintiff filed a motion for judgment on the pleadings or partial summary judgment, claiming that the Department failed to provide a factual basis for any claims of exemption. The plaintiff asserted that the case was similar to *May*, where the appellate court ordered the disclosure of similar records, ruling that their release would not invade patient privacy. The Department responded with its own cross-motion for summary judgment, claiming that the requested information was exempt from disclosure under the Illinois Health and Hazardous Substances Registry Act, which prohibits revealing the identity of individuals whose conditions are submitted to the registry. The Department cited FOIA provisions that allow for exceptions to disclosure when state law prohibits it. To support its position, the Department included an affidavit from Dr. Latanya Sweeney, who conducted an experiment showing that individuals could be re-identified from the Cancer Registry using the type of cancer, date of diagnosis, and ZIP code—despite the absence of direct identifiers. Dr. Sweeney concluded that this combination of data could lead to identification through publicly available datasets, underscoring the potential privacy risks associated with disclosing the requested information. The Department argued that the case at hand differed from the May case, as the May court did not receive evidence on how data from the Cancer Registry could be reidentified. The Department cited Dr. Sweeney's affidavit to assert that the disclosure of requested information could potentially reveal patient identities, thus prohibiting such disclosure. On December 31, 1998, the circuit court granted the plaintiff's summary judgment motion, ordering the Department to produce data on cancer patients while restricting any identification attempts. The Department's motion for reconsideration was denied on July 22, 1999. On appeal, the appellate court reversed the circuit court's decision, agreeing with the Department that section 7(1)(a) of the FOIA prevented the release of information protected by the Registry Act. The appellate court found a genuine issue of material fact regarding whether the requested information could lead to the identification of individuals. It concluded that a "reasonableness" standard should apply to determine if the information constituted a "group of facts which tends to lead to the identity" of patients, emphasizing that the Cancer Registry Act’s intent was to provide public information while preventing undue disclosures. The appellate court deemed the question of whether the requested information reasonably tended to lead to identifying individuals a factual issue. The appellate court determined that there was a genuine issue of material fact, leading it to reverse the trial court's summary judgment in favor of the plaintiff, and remanded the case for further proceedings. Upon remand, a bench trial occurred on June 6, 2002. Under the Freedom of Information Act (FOIA), the public body must prove that its denial of information disclosure complies with the FOIA. The Department of Public Health presented its case first, with Janice Snodgrass, manager of the Cancer Registry, as the initial witness. She explained that the Cancer Registry is a comprehensive surveillance system for cancer data collected from approximately 400 sources, mandated by the Registry Act, which includes reporting from hospitals, surgical centers, and voluntary contributions from certain physicians and labs. The registry maintains extensive patient demographic and medical information, including cancer type, diagnosis date, and treatment details, while ensuring strict confidentiality for individual patient data. Snodgrass noted that although public datasets are available on the Department's website, they contain limited information to protect patient privacy. The plaintiff’s request for specific neuroblastoma case data, including patient ZIP codes and diagnosis dates, was problematic because the public datasets do not identify specific cancer cases. To access more detailed information, the Registry Act requires requestors to submit an application and sign a confidentiality agreement, a process the plaintiff did not pursue. On cross-examination, Snodgrass acknowledged awareness of claims linking neuroblastoma to environmental factors but reiterated that the raw data is not publicly accessible, although it can be requested by scientists or researchers for investigative purposes. Dr. Latanya Sweeney, an assistant professor at Carnegie Mellon University and director of the Laboratory for International Data Privacy, served as the second and final expert witness for the Department. With a background that includes an undergraduate degree from Harvard and a Ph.D. from MIT, Dr. Sweeney has extensive experience as an expert in data privacy and anonymity, having consulted for various governmental agencies. In her testimony, she described an experiment conducted in 1998, where she was tasked with reidentifying individuals from the Cancer Registry using specific data fields: type of cancer, date of diagnosis, and patient ZIP code. Utilizing a standard laptop and spreadsheet software, Dr. Sweeney successfully identified a correct name for 18 of 20 data sets and suggested correct alternatives for the remaining cases, achieving a reidentification accuracy of 80% to 87%. Due to concerns that her detailed methodology might enable others to replicate her work, the circuit court sealed that portion of her testimony. However, it is noted that Dr. Sweeney employed a multistep method, beginning with research on neuroblastoma, and incurred approximately $2,000 in costs to obtain several publicly available and semi-public data sets. This involved filling out forms and receiving records via mail in CD format. Her comprehensive approach included searching for relevant information in these datasets, leveraging her research insights to aid in the identification process. Dr. Sweeney analyzed data sets containing approximately one million records to identify common factors in neuroblastoma cases. Initially selecting a broad factor, she realized it included too many unrelated cases, prompting her to focus on a more specific factor, which yielded a more accurate analysis. She utilized additional online resources, libraries, and newspaper archives to identify 18 out of 20 individuals in the Cancer Registry, primarily relying on publicly available data. Dr. Sweeney explained that the Cancer Registry served two key purposes: it narrowed her search parameters by ZIP code and validated her findings regarding the presence of neuroblastoma in the individuals identified. While she claimed she could identify neuroblastoma patients using public data alone, she emphasized that such identifications would lack confidence and accuracy without the Registry information, which she referred to as the "gold standard" for her analysis. She noted that using basic technology and software, such as spreadsheets, made it straightforward for anyone to identify individuals from the Cancer Registry. Following her testimony, the Department rested its case, and the plaintiff presented no witnesses. The circuit court then issued an oral ruling on the core issue framed by the appellate court, determining whether the sought information could reasonably lead to identifying individuals in the Cancer Registry, thus potentially violating the Registry Act and making the information exempt under the FOIA. The court concluded that the information requested by the plaintiff would not reasonably lead to the identification of specific individuals suffering from neuroblastoma. It determined that a reasonable person would lack the necessary computer skills, knowledge of databases, and analytical abilities to utilize the requested information effectively. The court emphasized that the information in isolation does not reveal identities but rather confirms data obtained from other sources. It acknowledged that Dr. Sweeney's unique expertise and access to specialized databases enabled her to identify individuals, a capability unlikely to be replicated by someone without her level of education and experience. Consequently, the court ordered the release of the requested data while prohibiting the plaintiff from attempting to identify individuals from the statistics. The appellate court upheld this ruling, rejecting the argument that anyone could derive identities from the data without the requisite expertise. The judgment affirmed that Dr. Sweeney’s ability to identify individuals stemmed from her specialized knowledge rather than the simplicity of her tools. The appellate court expressed skepticism that an average individual, lacking Dr. Sweeney's expertise, could replicate the complex methodology used to identify individuals in the Cancer Registry. It noted that Dr. Sweeney's testimony did not adequately quantify the risk of releasing such information to the plaintiff or the public. The court highlighted that although one data anonymity expert successfully identified subjects using a detailed six-step process, this did not substantiate a generalizable threat from data release or indicate how many individuals could achieve similar results. The court emphasized the importance of understanding the magnitude of the alleged threat in determining whether the released information would reasonably lead to identifying specific individuals. In its previous ruling, the court established a "reasonableness" requirement for assessing whether the requested information from the Cancer Registry could lead to identification. Upon applying this standard, the court concluded that the Department had not met its burden of proof. The court cautioned against equating the ability of one expert to identify individuals with a widespread threat of identification, which would undermine the reasonableness standard. The Department's petition for appeal was granted, alongside permission for media organizations to file an amicus curiae brief supporting the plaintiff. The appeal centers on whether the information sought by the plaintiff under the FOIA could lead to the identification of patients in violation of the Registry Act, which would exempt it from disclosure under the FOIA. The Department argued that the appellate court incorrectly upheld the decision requiring the disclosure of this information. Collection of health information raises significant privacy concerns for patients within the Cancer Registry. The Department emphasizes that the dissemination of this information, particularly to media outlets, heightens the risk of privacy loss. To mitigate this, the legislature enacted section 4(d) of the Registry Act, which prohibits not only the disclosure of patient identities but also any information that may "tend to lead" to identifying individuals whose data is included in the Registry. The Department argues that the lower courts misapplied the legal standard, straying from the statute's plain language. It criticizes the appellate court for introducing the term "reasonably" into the interpretation of "tends to lead," claiming this dilutes the legislative intent. The Department contends that evidence shows that the requested data—cancer type, diagnosis date, and ZIP code—could enable identification of 80% to 87% of individuals in the Registry. It asserts that access to public databases allows individuals to potentially identify patients, thus supporting its claim that the requested information violates the Registry Act's confidentiality provisions. The Department also refutes the appellate court's characterization of Dr. Sweeney's analysis as overly complex, maintaining that her testimony confirms the requested information indeed "tends to lead" to patient identities. The Department argues that Dr. Sweeney's testimony differentiates the current case from a prior appellate court decision in May, which stated that disclosing a patient's ZIP code, type of cancer, and diagnosis date would not likely reveal their identity. The Department claims that the facts presented in this case, influenced by Dr. Sweeney's testimony, contradict this assertion. It also criticizes the lower courts for focusing solely on one aspect of the Cancer Registry's purpose—public information dissemination—while neglecting its multiple goals. The Department contends that disclosing the requested information would likely identify cancer patients, thus violating section 4(d) of the Registry Act and making it exempt from disclosure under section 7(1)(a) of the FOIA. In contrast, the plaintiff argues that the appellate court correctly upheld the circuit court's ruling mandating the Department to fulfill the FOIA request. The plaintiff emphasizes that FOIA should favor disclosure and that exceptions should be narrowly interpreted. They assert that the public policy objectives of the Registry Act, particularly informing the public about cancer risks and treatments, support the release of the information. The plaintiff acknowledges the tension between patient privacy and community awareness but believes that the FOIA's liberal interpretation favors disclosure. They argue that the Department failed to prove that releasing the information would identify patients, highlighting that Dr. Sweeney utilized public data, not Cancer Registry data, to identify patients in her analysis. Dr. Sweeney testified that she used Cancer Registry information solely to validate her work. The plaintiff argues that adopting the Department's privacy stance—asserting that releasing data by diagnosis, date, and zip code invades privacy—would hinder the Registry Act's objectives, particularly in informing health professionals and communities about elevated cancer risks. The plaintiff cites a recent appellate court decision which found that disclosing similar neuroblastoma information was permissible, urging a consistent ruling here. The plaintiff has agreed not to use the Cancer Registry data to identify individuals if disclosure is granted. Amici curiae, including major news organizations, support the plaintiff, emphasizing the importance of FOIA for public oversight and arguing that public records should not be withheld without clear evidence of privacy invasion. They clarify that the plaintiff seeks "masked" data to investigate potential links between hazardous substances and cancer, a matter of significant public concern. The amici contend that the requested information does not reveal patient identities and that the lower courts rightly approved the FOIA request. The appeal focuses on whether the circuit court appropriately granted the request for disclosure of Cancer Registry neuroblastoma data, including cancer type, diagnosis date, and ZIP code. The court rejects the Department's arguments and concurs with the plaintiff's position, indicating that the lower courts correctly ordered the data's release. The analysis will consider the interplay between FOIA and the Registry Act, guided by established statutory interpretation principles. The court's primary goal in interpreting statutes is to discern and implement the intent of the General Assembly, starting with the statute's plain language as the most reliable indicator of legislative objectives. Statutory provisions must be viewed collectively, with words and phrases interpreted in context rather than in isolation. It is presumed that the legislature did not intend for its enactments to produce absurdity, inconvenience, or injustice. The Freedom of Information Act (FOIA) aims to promote transparency in government by ensuring public access to governmental records. Public records are generally presumed open and accessible, reflecting the General Assembly's policy that all individuals have the right to comprehensive information about government affairs to facilitate informed public discourse and oversight. While the FOIA acknowledges limited exceptions to protect individual privacy and the functioning of public bodies, these exceptions are narrowly construed to uphold the Act's overarching goal of public access to information. The court has consistently emphasized the need for a liberal interpretation of the FOIA to fulfill its purpose, ensuring that exceptions to disclosure do not undermine this intent. A public body must comply with information requests unless a specific exemption in Section 7 of the Freedom of Information Act (FOIA) applies. The exemptions are narrowly defined; one such exemption, Section 7(1)(a), protects information explicitly prohibited from disclosure by federal or state law. When a public body denies a request citing an exemption, it must provide written notice of the specific exemption claimed. Individuals denied access can appeal the decision to the head of the public body and may seek judicial review in circuit court if the denial is upheld or not acted upon within certain timeframes. The circuit court reviews these appeals de novo and can examine the records in question to determine if the public body justifiably withheld them. The burden of proof lies with the public body to demonstrate that the denial aligns with FOIA provisions and that the records fall under the claimed exemption. In the case at hand, the Department must show that the Cancer Registry records are exempt under Section 7(1)(a) due to state law prohibiting their disclosure, specifically citing section 4(d) of the Registry Act, which aims to protect the identities of individuals whose health information is submitted to the registry. A significant concern regarding public health and welfare in Illinois was identified by the General Assembly, specifically regarding hazardous substances and the absence of a coordinated effort to gather and analyze related information and its health effects. This lack of comprehensive data led to public anxiety and ineffective state control. In response, the General Assembly enacted the Registry Act, which mandates the development of a comprehensive data system to inform and protect citizens about hazardous substances and public health. The Registry Act aims to establish a unified statewide initiative to collect and analyze information on public health and hazardous substances. Its objectives include monitoring cancer incidence trends, targeting intervention resources for affected communities, educating health professionals and the public about cancer risks, and promoting quality research for better cancer control. However, the Act also incorporates provisions to limit public access to certain sensitive information to protect the privacy of individuals with cancer. Specifically, section 4(d) defines confidential information, including any identifying details about individuals submitted to the registry. Amendments to section 4(d) clarified what constitutes identifying information, including names and social security numbers, reinforcing confidentiality. Additionally, section 4(e) mandates the protection of confidential information, while section 12 allows public access to the registry data, provided it does not disclose any privileged information. The statutory provisions illustrate a balance between the need for public access to information about cancer clusters and the imperative to protect patient privacy. Section 4(d) of the Registry Act prohibits the disclosure of publicly available information if it tends to reveal the identities of cancer patients in the Registry. This analysis applies to both the original and amended versions of section 4(d), which includes a nonexclusive list of facts that may lead to identification. The term "tends" is interpreted to allow for case-by-case determinations regarding information disclosure, reflecting the legislature’s intent for flexibility. This term indicates a heightened confidentiality standard, as it goes beyond merely prohibiting information that leads to identity, but does not create an absolute barrier to disclosure. The inherent tension in the Act aims to balance public access to information about hazardous substances and the protection of patient identities. The court disagreed with the appellate court's assertion that the word "reasonably" should be added to the phrase "tends to lead to the identity," asserting that such an addition is unnecessary and driven by concern over extreme hypothetical scenarios. The legislature's choice of the word "tends" allows for adaptable analysis based on specific circumstances surrounding the release of Cancer Registry information. The appellate court expressed concern that the term "tends" might create a blanket exemption from disclosure under section 4(d) of the Registry Act, which could undermine legislative intent. The court believed the legislature aimed to establish a flexible standard for evaluating cases based on their individual facts. The Department argued that the information sought by the plaintiff is exempt from disclosure because it could lead to identifying patients in the Cancer Registry, supported by Dr. Sweeney’s expert testimony. However, the court highlighted ambiguity in whether the disclosure prohibition relies on the capability of experts or the general public to identify patients. The court emphasized the necessity of public disclosure of government information, noting that under the Freedom of Information Act (FOIA), public records are generally presumed to be open with narrow exceptions. It concluded that information only "tends to lead to the identity" of Registry patients if it can be utilized by the general public for identification purposes. While Dr. Sweeney demonstrated that an expert could identify patients using the requested information, the Department did not provide evidence that an average member of the public could replicate this identification process without significant expertise, resources, and knowledge. Dr. Sweeney's testimony suggested that the general public could identify patients listed in the Cancer Registry; however, the Department provided no evidence to support this claim beyond her assertion. The circuit court determined that Dr. Sweeney's ability to identify these patients stemmed from her knowledge, education, and experience, finding no contradiction in the evidence presented. The court noted that Dr. Sweeney's methodology was more complex than the Department claimed, contrary to their assertions about the simplicity of her experiment. Although Dr. Sweeney stated that the equipment and data she used were accessible to the public, her unique six-step identification process required specialized knowledge and skills that go beyond the capabilities of an average individual. This process involved recognizing relevant statistical data, integrating and analyzing information, and solving complex problems. The court highlighted that Dr. Sweeney's ability to correct her initial broad factor in case analysis demonstrated her advanced expertise. Despite the trial judge's efforts to understand her method in detail, Dr. Sweeney's explanations lacked clear specificity on how easily others could replicate her work. The defendants failed to present additional evidence to counter this assessment. Defendants, despite having access to extensive resources, failed to present specific evidence that other individuals could replicate Dr. Sweeney's work, nor did they call additional witnesses to support their claims. As a result, the court determined that it could not assess the defendants' concerns effectively based on the limited evidence provided. The court reiterated that the Department had the burden under the Freedom of Information Act (FOIA) to justify its refusal to release the requested Cancer Registry information by demonstrating it fell under the exemption in section 7(1)(a) of the FOIA and was prohibited by section 4(d) of the Registration Act. Lacking conclusive evidence that the public could replicate Dr. Sweeney's complex experiment, the court emphasized the state's public policy favoring information disclosure and interpreted the FOIA liberally, with narrow interpretations of exemptions. Consequently, the lower courts' ruling requiring the Department to release the requested information was upheld. Additionally, the circuit court mandated that the plaintiff not identify individuals on the Cancer Registry list, ensuring confidentiality. The appellate court's judgment was affirmed.
