ORIGINAL PROCEEDING IN PROHIBITION 
 
 
Tyler Technologies, Inc., filed a petition for a writ of prohibition to bar the circuit 
court from taking further action other than dismissing with prejudice Counts IV and VI of 
a class-action petition filed by several individual and corporate property owners (Plaintiffs) 
who allege Tyler negligently performed its contractual obligations to assist Jackson County 
with the 2023 real property assessment.  Tyler is entitled to dismissal as a matter of law 
because Plaintiffs do not allege facts showing Tyler owed them a duty of care.  
Consequently, this Court makes permanent its preliminary writ prohibiting the circuit court 
from taking any further action other than dismissing Counts IV and VI of the first amended 
petition with prejudice.

Facts and Procedural History 
 
Plaintiffs alleged the County, several government officials, and Tyler acted 
unlawfully during the 2023 real property assessment, resulting in illegal assessments.  
Plaintiffs alleged Tyler entered into a contract to replace the County's computer-assisted 
mass appraisal system and provided the County with appraisal and reassessment services.  
Plaintiffs alleged Tyler owed them "a duty to use reasonable care when performing" 
services pursuant to the contract.  As relevant to this case, they further alleged Tyler's 
failure to perform its contractual obligations caused some class members to not receive 
timely notice of increased assessments (Count IV) and caused others to have their property 
assessments increase by more than 15 percent without a physical inspection pursuant to 
§ 137.1151 (Count VI).  
Tyler filed a motion to dismiss Counts IV and VI on grounds Plaintiffs failed as a 
matter of law to allege facts showing Tyler owed Plaintiffs a duty of care.  The circuit court 
overruled the motion to dismiss.  Tyler filed a petition for a writ of prohibition and this 
Court issued a preliminary writ of prohibition.  
Prohibition 
 
This Court has jurisdiction to issue original remedial writs.  Mo. Const. art. V, § 4.1. 
This Court may issue a writ of prohibition: 
(1) to prevent the usurpation of judicial power when a lower court lacks 
authority or jurisdiction; (2) to remedy an excess of authority, jurisdiction or 
abuse of discretion where the lower court lacks the power to act as intended; 
or (3) where a party may suffer irreparable harm if relief is not granted.

State ex rel. Wishom v. Bryant, 673 S.W.3d 88, 93-94 (Mo. banc 2023).  Prohibition is an 
appropriate remedy to avoid irreparable harm when the "plaintiff's petition does not state a 
viable theory of recovery, and relator was entitled to be dismissed from the suit as a matter 
of law."  State ex rel. Henley v. Bickel, 285 S.W.3d 327, 330 (Mo. banc 2009) (internal 
quotation omitted).   
Standard of Review 
 
A motion to dismiss for failure to state a claim tests whether the petition adequately 
alleged facts stating a recognized cause of action or one that may be adopted.  Id. at 329.  
"When considering whether a petition fails to state a claim upon which relief can be 
granted, this Court must accept all properly pleaded facts as true, giving the pleadings their 
broadest intendment, and construe all allegations favorably to the pleader."  Tuttle v. Dobbs 
Tire & Auto Ctrs., Inc., 590 S.W.3d 307, 310 (Mo. banc 2019) (internal quotation omitted).  
Analysis 
 
To state a negligence claim, the plaintiff must allege facts showing: "(1) the 
defendant had a duty to the plaintiff; (2) the defendant failed to perform that duty; and 
(3) the defendant's breach was the proximate cause of the plaintiff's injury."  McComb v. 
Norfus, 541 S.W.3d 550, 554 (Mo. banc 2018).  The dispositive issue in this case is whether 
Plaintiffs alleged facts showing Tyler owed them a duty of care.  
"Whether a duty exists is purely a question of law."  Tharp v. St. Luke's Surgicenter-
Lee's Summit, LLC, 587 S.W.3d 647, 654 (Mo. banc 2019) (internal quotation omitted).  A 
duty of care may be imposed by statute or ordinance, assumed by contract, or arise pursuant 
to common law under the circumstances of the case.  Scheibel v. Hillis, 531 S.W.2d 285, 
4 
 
288 (Mo. banc 1976).  
Plaintiffs allege the "general reassessment process is statutorily driven" and requires 
the County assessor to complete various steps of the process by certain dates to enable 
timely administrative review of challenged assessments.  As § 137.115.1 makes clear, the 
duty to "annually assess all real property" lies with the "assessor."2  Consistent with this 
duty, the statutory notice and physical inspection requirements alleged by Plaintiffs are 
duties imposed on the "assessor," not private, third-party contractors like Tyler.  
Plaintiffs' allegation that Tyler owed them a duty of care is premised on Tyler's 
performance of its contractual obligations to the County.  This alleged duty, however, is 
foreclosed by the rule of privity, which generally provides a party to a contract owes "no 
duty to a plaintiff who was not a party to the contract where there was no privity or direct 
transaction between them."  Westerhold v. Carroll, 419 S.W.2d 73, 76 (Mo. 1967).  
The rule of privity exists for two reasons.  First, it curtails "excessive and unlimited 
liability."  Id. at 77.  Second, it preserves the right to make contracts by not burdening the 
contracting parties "with obligations and liabilities to others which parties would not 
                                                 
2 Chapter 137 does not define the term "assessor," but the context and plain meaning of the term 
refers to the elected or appointed officeholder responsible for assessing property for taxation.  As 
§ 53.010.1 makes clear, the "assessor" is a public office, not a private contractor.  "The assessor's 
duty is "to assess all of the real and tangible personal property in the county in which he assesses 
at what he believes to be the actual cash value."  § 53.030.  The assessor is authorized to appoint 
deputies to carry out the assessor's official duties.  §§ 53.060; 137.715.  While Plaintiffs allege 
Tyler and its employees were "de facto" employees of the assessor, they do not allege Tyler and 
its employees were deputies appointed to carry out the assessor's official duties pursuant to 
§ 53.060, § 137.715, or any other statute.

voluntarily assume."  Id.  (internal quotation omitted).  While the rule of privity is not 
absolute, Missouri courts "have not relaxed" the rule in cases in which the two reasons for 
the rule are present.  Id.  
In this case, both reasons for the rule of privity are present, and Plaintiffs do not 
plead a recognized exception.3  Disregarding the rule of privity and imposing tort liability 
in this case would subject Tyler to "excessive and unlimited liability" to a putative class 
consisting of an unknown number of individuals, corporations, and other legal entities 
owning real property located in the County.  Westerhold, 419 S.W.2d at 77.  Moreover, 
concluding Tyler is liable for the County's failure to meet its statutorily mandated duties 
would also disincentivize local government contractors from entering into service contracts 
by creating "obligations and liabilities to others which parties would not voluntarily 
assume."  Id.4  
Although the reasons for the rule of privity are present in this case, Plaintiffs argue 
the rule does not apply because they pleaded facts showing it was foreseeable Tyler's 
actions could result in unlawful assessments.  Plaintiffs cite the Restatement (Second) of 
                                                 
3 Westerhold noted the rule of privity generally does not apply to an architect's potential liability 
to third parties or to cases involving negligent acts posing an imminent danger, inherently 
dangerous products, fraud, collusion, warranties, or the negligent transmission of "telegrams."  419 
S.W.2d at 77.  
4 In cases in which these two reasons are absent, the determination of whether a third party not in 
privity with the defendant may maintain a negligence action "involves the balancing of various 
factors, among which are the extent to which the transaction was intended to affect the plaintiff, 
the foreseeability of harm to him, the degree of certainty that the plaintiff suffered injury, the 
closeness of the connection between the defendant's conduct and the injury suffered, the moral 
blame attached to defendant's conduct, and the policy of preventing future harm."  Westerhold, 
419 S.W.2d at 81.  This additional analysis is unnecessary because both reasons for the rule of 
privity are present in this case.   
6 
 
Torts, § 324A, and several Missouri cases declining to apply the rule of privity due to the 
foreseeability of harm under circumstances not present in this case.5  Neither the 
Restatement nor the cited cases overcome the rule of privity and salvage Plaintiffs' 
negligence claims.  
 
Section 324A does not apply because it is expressly limited to cases involving 
"liability to the third person for physical harm[.]"  Plaintiffs allege economic damage from 
unlawful assessment, not physical harm.  Plaintiffs' reliance on personal injury and 
wrongful death cases fails for the same reason.6  The remaining cases Plaintiffs cite involve 
a third party's reliance on a defendant's performance of its contractual obligations.7  Unlike 
this case, none of these cases involved potential "excessive and unlimited liability" in a 
class action or the assumption of "obligations and liabilities to others which parties would 
                                                 
5 This Court has cited § 324A as an analytical guide for assessing negligence actions brought by 
third parties claiming a defendant's negligent performance of its contractual obligations created a 
foreseeable risk of harm giving rise to a tort duty of care.  See L.A.C. ex rel. D.C. v. Ward Parkway 
Shopping Ctr. Co., 75 S.W.3d 247, 263 (Mo. banc 2002); J.M. v. Shell Oil Co., 922 S.W.2d 759, 
765 (Mo. banc 1996).  
6 Plaintiffs cite the inapposite cases of Brown v. Michigan Millers Mutual Insurance Co., Inc., 665 
S.W.2d 630 (Mo. App. 1983) (personal injury), and Kraus v. Hy-Vee, Inc., 147 S.W.3d 907 (Mo. 
App. 2004) (wrongful death).  
7 See Children's Wish Found. Int'l, Inc. v. Mayer Hoffman McCann, P.C., 331 S.W.3d 648, 653 
(Mo. banc 2011) (noting a third party, although not in privity, may have a negligence claim against 
a professional who renders an opinion upon which the third party relies); Kaplan v. U.S. Bank, 
N.A., 166 S.W.3d 60, 71 (Mo. App. E.D. 2003) (holding lack of privity did not bar suit against 
defendant who dumped contaminated soil on the plaintiff's property because the defendant agreed 
to properly dispose of contaminated materials only at permitted landfills or on the defendant's 
property); Miller v. Big River Concrete, LLC, 14 S.W.3d 129, 131 (Mo. App. 2000) (holding lack 
of privity did not bar homeowners' suit against defendant who tested concrete and had reason to 
expect the homeowners would rely on the test results); Aluma Kraft Mfg. Co. v. Elmer Fox & Co., 
493 S.W.2d 378, 383 (Mo. App. 1973) (holding lack of privity did not bar suit against an 
accountant who prepared an audit because it was foreseeable the plaintiff would rely on the audit).

not voluntarily assume."  Westerhold, 419 S.W.2d at 77.  These cases do not implicate the 
reasons for the rule of privity and are distinguishable.  
Plaintiffs also argue they pleaded facts showing Tyler owed them a common law 
duty because unlawful assessments were a foreseeable result of Tyler's alleged negligent 
conduct.  "In the absence of a particular relationship recognized by law to create a duty, 
the concept of foreseeability is paramount in determining whether a duty exists."  Lopez v. 
Three Rivers Elec. Co-op., Inc., 26 S.W.3d 151, 156 (Mo. banc 2000).  As established, 
however, the rule of privity tempers the common law foreseeability test by generally 
providing a party to a contract owes no tort duty to a plaintiff who was not a party to the 
contract.  Westerhold, 419 S.W.2d at 76.  As established, the pleaded facts demonstrate as 
a matter of law that the rule of privity applies and precludes finding Tyler owed a duty of 
care to Plaintiffs based on its contractual obligations to the County. 
Conclusion 
 
Tyler is entitled to dismissal of Counts IV and VI of Plaintiffs' first amended 
petition.8  The preliminary writ is made permanent.9

8 Consistent with State ex rel. Jackson County, v. Chamberlain, SC100304, which was issued today 
and involves the same underlying lawsuit, dismissal also is warranted because Plaintiffs filed the 
underlying negligence action challenging legality of property tax assessments without first 
exhausting their statutory administrative remedies as required by chapters 137 and 138.   
9 No Rule 84.17 motions for rehearing shall be filed in this matter.
