Summary
The Illinois Supreme Court considered whether Chicago was required to obtain Illinois Department of Transportation certification before undertaking terminal and ground transportation improvements at O’Hare International Airport under section 47 of the Illinois Aeronautics Act. The court held that the statute was ambiguous and deferred to IDOT’s reasonable interpretation, under which certification is required for alterations materially affecting runway size or layout or interfering with specified flight paths and zones. The court upheld summary judgment for Chicago and addressed related issues concerning federal preemption and intervention.
Holdings
- Section 47 is ambiguous, and IDOT's reasonable interpretation requires a certificate of approval only for airport alterations or extensions that materially alter runway size or layout or interfere with or otherwise obstruct an approach slope, transition slope, or turning zone. The terminal and ground transportation improvements at issue did not require certification because the record did not show that they would have those effects.
- Summary judgment for Chicago was proper because no genuine issue of material fact existed concerning whether the proposed terminal and ground transportation improvements would trigger section 47's certification requirement.
- The appellate court's anti-segmentation theory was rejected. Chicago's construction of terminal and ground transportation projects in anticipation of future runway expansion does not itself trigger certification for those projects, but Chicago must obtain certification before actually undertaking qualifying runway alterations or other improvements affecting protected flight zones.
- The circuit court did not abuse its discretion in denying intervention because the proposed intervenors identified no statute granting a conditional or unconditional right to intervene and did not show an interest greater than that of the general public or inadequate representation by the existing plaintiffs.
Questions Presented
- Whether section 47 of the Illinois Aeronautics Act requires IDOT certification before Chicago undertakes the terminal and ground transportation improvements at issue.
- Whether the appellate court's theory that Chicago could not avoid certification by segmenting a larger airport expansion plan was correct.
- Whether the circuit court abused its discretion by denying Congressman Henry J. Hyde and State Senator James Philip's request to intervene.
- Whether the appeal should be dismissed as presenting an uncertain or advisory controversy because of changes in Chicago's plans.
