State's Attorney outlines legal tests judges use in land‑use suits and urges board to confine deliberations to public hearings

A representative of the Will County State's Attorney's Office reviewed the legal standards courts apply when property owners sue the county over denials of zoning relief and special‑use requests, and warned board members that off‑record contacts and informal site visits can complicate defense of those decisions.

The presenter, Matt, summarized two categories of constitutional claims—procedural due process and substantive due process—and said substantive challenges are most common in land‑use litigation. He told the committee that courts use the LaSalle and Sinclair cases’ factors—six from LaSalle and two added in Sinclair, commonly described together as eight factors—in a balancing test to decide whether a denial was “arbitrary, capricious, and unreasonable.” Matt said, “procedural due process a plaintiff is merely entitled to notice of a proceeding and an opportunity to present their position,” and that more often plaintiffs raise substantive claims tested against the LaSalle/Sinclair factors.

Why it matters: Board members decide land‑use requests that can be appealed to court. Legal counsel told the committee that judges will scrutinize what the board considered and how it reached a decision; the clearer the record that the board relied on legitimate planning factors, the harder it is for plaintiffs to show a denial was arbitrary.

Inverted‑pyramid details: Matt listed commonly applied factors courts examine, including “the existing uses and the zoning of nearby property,” the extent property values are affected, the balance between public gain and private hardship, the suitability of the property for the zone’s purposes, and the length of time a parcel has remained vacant. He explained that the Sinclair additions ask whether the community needs the proposed use and how carefully the community has planned land development—citing Will County’s Land Resource Management Plan (LRMP) as an example of a planning document a court may consider.

Board members asked how to apply the factors in practical situations such as airports and long‑established industrial sites. Matt and other legal staff said expert testimony (appraisers, traffic or safety experts) is often decisive in court and that judges give deference to land‑use bodies when decisions are “rationally related” to legitimate government interests. Matt said courts will also consider any standards set by the legislative body (for example, county zoning rules) in addition to the LaSalle/Sinclair factors.

On conduct and process, county legal staff including Kevin and other presenters repeatedly advised board members to confine substantive deliberations and evidence‑gathering to the official public hearing (Planning and Zoning Commission, often abbreviated PCC, and the statutorily required hearing). They recommended directing constituents to present evidence at the public hearing rather than in one‑on‑one meetings so opposing parties have an opportunity to test testimony. As one staff member put it, such evidence belongs in “the public hearing” because otherwise “it never happened” for legal purposes.

The state's attorney and county staff addressed common questions: whether long‑standing uses are “grandfathered,” whether members may visit sites, and how municipal objections near county borders factor in. Counsel said grandfathering protects legally established pre‑existing uses but generally does not authorize expansions beyond the previously established use; site visits carry legal risk because off‑record observations or private conversations can be used in discovery; and municipal resolutions or border concerns factor into a board member’s deliberations but do not transfer legal voting authority.

Members also raised solar permitting. Counsel said the 2023 state statute applicable to large solar projects sets a separate, statutory five‑point test; where that statute applies, the LaSalle/Sinclair analysis is not the controlling framework and the statutory criteria (and the county ordinance derived from it) govern the review.

Ending: The committee did not take substantive votes on land‑use applications during the session. Legal counsel said they will provide a written list of the LaSalle/Sinclair factors and follow‑up materials to the board. Several members asked county staff and legal counsel to prepare template language and public guidance explaining why members should encourage constituents to use the public‑hearing process.
