Ronald Calzone v. Eric T. Olson, 931 F.3d 722

Background

Ronald Calzone operates a 54,000-pound dump truck in support of his Eagle Wings Ranch and holds a Missouri commercial driver’s license and an "F" (farm) plate.
A Missouri state trooper stopped Calzone in June 2013 and sought to perform a random roadside inspection authorized by Mo. Rev. Stat. § 304.230; Calzone refused and sued under 42 U.S.C. § 1983 seeking declaratory and injunctive relief.
The sole remaining claim on appeal challenged the superintendent’s authority to authorize random, suspicionless inspections of Calzone’s truck.
The Fourth Amendment generally requires a warrant and probable cause, but closely regulated industries may be subject to warrantless inspections under the Burger test.
Missouri’s regulatory scheme applies federal motor-carrier safety rules to many intrastate commercial vehicles, requires registration, weight/size limits, periodic inspections, and authorizes random roadside commercial-vehicle inspections.
Calzone claimed he was exempt (intrastate use, farm vehicle, private carrier) and thus not within the closely regulated industry; the court held he remains subject to substantial regulation and to random inspections.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Calzone is part of a "closely regulated" commercial trucking industry such that warrantless random inspections are permissible	Calzone: his truck is intrastate/farm/private and largely exempt from federal regs, so he is not within the closely regulated industry	State: Missouri law expands federal definitions to cover intrastate commercial motor vehicles and subjects Calzone’s truck to substantial regulation	Held: Calzone is within the closely regulated commercial trucking industry; Missouri’s scheme applies to him
Whether Missouri’s inspection statute advances a substantial governmental interest	Calzone: his limited farm use reduces the State’s interest	State: highway safety and infrastructure protection are substantial interests regardless of for-hire status	Held: The State has a substantial interest as applied to Calzone
Whether warrantless inspections are necessary to further the regulatory scheme	Calzone: targeted probable-cause requirement should apply	State: random roadside inspections are necessary given transitory nature and enforcement difficulties	Held: Warrantless random inspections are necessary to effectively enforce the scheme
Whether § 304.230 is a constitutionally adequate substitute for a warrant (notice, scope, and limits on officer discretion)	Calzone: statute fails to define scope, give adequate notice, and limit officer discretion	State: statute notifies drivers of potential inspections and limits inspections to regulatory compliance	Held: The statute is a permissible substitute for a warrant; random stops/inspections comport with Fourth and Fourteenth Amendments
