Administrative Adjudication of Overweight-Vehicle Violations: Three Illinois Decisions
Illinois municipalities use several procedures to enforce vehicle-weight ordinances. Depending on the applicable statutes and local ordinances, a violation may be processed through a municipal administrative hearing system or by a uniform traffic citation filed in circuit court.
Three Illinois decisions—Catom Trucking, Inc. v. City of Chicago, Cammacho v. City of Joliet, and Solano v. City of Chicago—address the authority of municipalities to adjudicate overweight-vehicle violations administratively. The cases also discuss local enabling ordinances, reportable offenses, monetary penalties, bonds, vehicle detention, and enforcement of administrative decisions.
Because citation procedures vary by municipality and the circumstances of the violation, enforcement officers should discuss available options with their city attorney, command staff, and municipal administrators.
Catom Trucking, Inc. v. City of Chicago
In Catom Trucking, Inc. v. City of Chicago, a trucking company, its owner, and two drivers challenged several Chicago practices involving overweight vehicles and permits. Chicago’s Department of Administrative Hearings had adjudicated alleged violations of sections 9-72-070 and 9-72-080 of the Chicago Municipal Code.
The Illinois Appellate Court initially concluded that the Department of Administrative Hearings lacked jurisdiction over the violations. The court interpreted section 1-2.1-2 of the Illinois Municipal Code as excluding offenses under the Illinois Vehicle Code, similar regulations governing vehicle movement, and reportable offenses under section 6-204 of the Vehicle Code from municipal administrative adjudication. [1]
That jurisdictional portion of Catom was subsequently overruled by the Illinois Supreme Court in Cammacho. Other portions of Catom, however, addressed separate enforcement questions.
For example, the appellate court determined that section 15-112 of the Illinois Vehicle Code did not prohibit Chicago from authorizing employees other than police officers to stop or detain overweight vehicles. The court also found that Chicago’s ordinance authorized the City to require a bond equal to the minimum fine.
The court drew a distinction between requiring a bond and detaining a vehicle until the bond was posted. Although Chicago’s ordinance authorized the bond, the City did not identify a statute or ordinance that authorized employees to prevent the vehicle from leaving as a substitute for posting the bond. The court therefore affirmed the bond requirement but reversed the ruling concerning detention of the vehicle pending payment.
Cammacho v. City of Joliet
Cammacho v. City of Joliet involved five commercial truck drivers cited for violating Joliet ordinances governing overweight or overlength vehicles on nondesignated roads. The City issued municipal ordinance violation notices and adjudicated the cases through its administrative code hearing unit. The hearing officer found the drivers liable and imposed fines and costs.
The appellate court reversed the administrative decisions, citing Catom. The Illinois Supreme Court affirmed the reversal, but it relied on different reasoning.
The Supreme Court held that section 1-2.1-2 of the Illinois Municipal Code does not preempt the independent constitutional authority of a home-rule municipality to create an administrative-adjudication system. Under the Illinois Constitution, home-rule powers are construed liberally. A state statute limits those powers only when the General Assembly expressly states the limitation and identifies its extent. [2]
The Court explained that section 1-2.1-2 defines the types of proceedings included within the statutory administrative system established by that division of the Municipal Code. It does not expressly prohibit a home-rule municipality from adopting another administrative system under its constitutional authority. The Supreme Court therefore overruled the portion of Catom holding otherwise.
Joliet nevertheless could not use administrative adjudication for the citations at issue because of its own ordinance. Section 3-5 of the Joliet Code directed that traffic offenses requiring reporting to the Illinois Secretary of State be reported to the circuit court. Non-reportable ordinance or traffic violations could be assigned to the City’s administrative process.
Section 6-204 of the Illinois Vehicle Code generally requires the reporting of qualifying violations, other than parking violations, when the driver holds a commercial driver’s license or commercial learner’s permit. The reporting requirement may also apply when a violation is committed in a statutorily defined commercial motor vehicle. [3]
The plaintiffs were commercial truck drivers, and the weight and length ordinances were similar to provisions of the Illinois Vehicle Code. The Supreme Court concluded that the violations were reportable under section 6-204. Consequently, Joliet’s own ordinance required the use of uniform traffic citations returnable in circuit court rather than municipal notices adjudicated by its code-hearing unit.
Cammacho distinguishes a municipality’s general home-rule authority from the authority provided by its local code. A municipality may have constitutional power to establish an administrative system, even if its existing ordinance assigns a particular category of cases to the circuit court.
Solano v. City of Chicago
In Solano v. City of Chicago, the City issued a commercial truck driver a citation alleging that his tractor-trailer weighed 26,000 pounds and exceeded the applicable limit by 16,000 pounds. The citation identified a potential fine of $2,655 and informed the driver that he could request a hearing before Chicago’s Department of Administrative Hearings.
The driver filed a lawsuit challenging the Department’s authority. Following the Supreme Court’s decision in Cammacho, he withdrew claims based on section 1-2.1-2 of the Municipal Code. His remaining claims alleged that sections 11-208.2 and 11-208.3 of the Illinois Vehicle Code limited Chicago’s administrative authority and capped the permissible fine. [4]
The Illinois Appellate Court determined that Chicago’s home-rule authority permitted its Department of Administrative Hearings to adjudicate weight violations. Chicago Municipal Code section 9-72-100 expressly gave the Department authority to conduct hearings following the issuance of weight citations.
The court also concluded that sections 11-208.2 and 11-208.3 did not expressly limit Chicago’s authority over weight violations. Those provisions address categories such as standing, parking, vehicle compliance, automated traffic laws, and automated speed-enforcement violations. Weight violations are addressed separately in Chapter 15 of the Vehicle Code.
The court rejected the argument that Chicago’s use of the phrase “permit to remain” converted an overweight violation into a standing or parking violation. Because the relevant state provisions did not expressly apply to vehicle-weight violations, they did not restrict Chicago’s home-rule authority to conduct the administrative hearing.
The court affirmed the dismissal of the driver’s claims. It did not decide what mechanisms Chicago could use to enforce an administrative fine or convert an administrative determination into an enforceable court judgment. The court stated that adjudicatory authority and enforcement procedures are separate questions.
Considerations for Enforcement Officers
Before any municipality begins issuing citations for overweight vehicles through a local administrative adjudication process, legal counsel should be sought. The issue is very complicated, and recent court decisions have not clarified the many nuances of the legality. Because any uniform traffic citation issued to a CDL or CLP holder must be reported to the Illinois Secretary of State, it is our position that municipalities should refrain from prosecuting overweight vehicle citations through local administrative adjudication.
