Richard Robinson appeals the dismissal of his negligence claim against his co-employee, Cheryl Hooker, following a workplace accident. Robinson contends the circuit court erred in determining his negligence claim was barred by the exclusivity provisions of the Workers’ Compensation Act and the doctrines of res judicata and official immunity. For reasons explained herein, we reverse the dismissal and remand the cause to the circuit court.
I. Factual and Procedural History
On October 23, 2007, Robinson and Hooker were performing street cleaning tasks as employees of the City of Kansas City, Missouri. Hooker lost her grip on a high pressure hose that swung wildly and struck Robinson, causing blindness in his right eye. Robinson filed a workers’ compensation claim for permanent partial disability benefits, which he settled with the City on January 30, 2009.
Two months later, Robinson filed a Petition against Hooker in the Jackson County Circuit Court. The petition alleged that Robinson suffered an eye injury as a result of Hooker’s negligence in failing to use ordinary care while operating a high pressure hose. The petition also included a loss of consortium claim for Robinson’s wife, Nadine. Hooker filed a Motion to Dismiss, asserting the court lacked subject matter jurisdiction because the Workers’ Compensation Act provided Robinson’s exclusive remedy for his injury claim against a co-employee. Alternatively, the motion asserted that Robinson’s negligence claim was barred by the doctrines of res judica-ta and official immunity.
The circuit court granted Hooker’s motion without explanation. Robinson appeals the dismissal of his petition.
II. Standard of Review
A motion to dismiss is an attack on the petition and solely a test of the adequacy of the pleadings.
Wheeler v. Sweezer,
When the circuit court does not provide reasons for dismissing a petition, we must presume the decision was based on the grounds stated in the motion to dismiss.
Duvall v. Lawrence,
*422 III. Issues on Appeal
A. Workers’ Compensation Act
In her Motion to Dismiss, Hooker argued the circuit court lacked subject matter jurisdiction because the Workers’ Compensation Act, Section 287.120, 1 provides the exclusive remedy for Robinson’s injury claim against a co-employee. Robinson contends the court erred in dismissing his petition on this ground because the Act does not bar civil claims against co-employees, based on a 2005 amendment requiring strict construction of the exclusivity provision. § 287.800.
As a preliminary matter, we find that Hooker’s defense of immunity under the Workers’ Compensation Act did not raise a jurisdictional defect. In
McCracken v. Wal-Mart Stores E., LP,
Because McCracken was decided while this case was pending, we must consider Hooker’s claim of immunity as preserved by the filing of her motion to dismiss. Id. at 480. For purposes of this appeal, we will proceed as if Hooker had filed a responsive pleading asserting the affirmative defense of employer immunity under Section 287.120. This procedural posture allows us to address the issue presented: Whether Hooker, as Robinson’s co-employee, can properly seek immunity from the civil suit based on a strict construction of the Act’s exclusivity provisions.
1. History of Co-Employee Immunity
Historically, prior to the passage of workers’ compensation laws, an employer was not liable for injuries to an employee caused by the negligent acts of a “fellow servant.”
Bender v. Kroger Grocery & Baking Co.,
In 1926, the Workmen’s Compensation Act made the employer responsible for providing benefits to injured employees in exchange for the employer receiving immunity against tort claims for the injuries.
Gunnett v. Girardier Bldg. & Realty Co.,
In
Badami,
this judicial extension of immunity was deemed necessary to “fix” the Act’s omission of agency principles in determining liability for workplace injuries.
Id.
at 178. Under
Badami
and its progeny, a co-employee could not be sued unless there was a showing of “something more” than a breach of the employer’s duty to provide a safe workplace.
Id.
at 180;
State ex rel. Taylor v. Wallace,
2. Statutory Construction
Prior to 2005, Section 287.800 mandated that “[a]ll provisions of [the Workers’ Compensation Act] shall be liberally construed with a view to the public welfare.” Under this standard, courts broadly interpreted the Act to extend benefits to the largest possible class and resolved any doubts as to the right of compensation in favor of the employee.
Schuster v. State Div. of Emp’t Sec.,
In 2005, the Act was amended to eliminate the requirement of liberal construction. Section 287.800 now provides:
Administrative law judges, associate administrative law judges, legal advisors, the labor and industrial relations commission, the division of workers’ compensation, and any reviewing courts shall construe the provisions of this chapter strictly.
(Emphasis added.) This change requires the courts to use principles of strict construction in applying all provisions of the workers’ compensation statute.
Strict construction means that a “statute can be given no broader application than is warranted by its plain and unambiguous terms.”
Harness v. S. Copyroll, Inc.,
3. Strict Construction of Employer Immunity Provisions
Based on the new requirement of strict construction, Robinson argues that the exclusivity provisions of the Workers’ Compensation Act, which grants employer immunity from civil claims, cannot be applied to co-employees. Section 287.120 of the Act provides:
1. Every employer subject to the provisions of this chapter shall be liable, irrespective of negligence, to furnish compensation under the provisions of this chapter for personal injury or death of the employee by accident arising out of and in the course of the employee’s employment, and shall be released from all other liability therefore whatsoever, whether to the employee or any other person.
2. The rights and remedies herein granted to an employee shall exclude all other rights and remedies of the employee ... at common law or otherwise, on account of accidental injury or death, except such *424 rights and remedies as are not provided for by this chapter.
The first paragraph of this section only refers to an “employer” being released from liability in exchange for providing workers’ compensation benefits. Because there is no provision releasing employees from liability to their injured co-workers, Robinson contends the immunity is exclusively available to employers. Strict construction requires this court to interpret and apply the Act based on its plain language. Robinson asserts there is nothing in the Act to indicate that the term “employer” includes co-employees; thus, the more liberal application and extension of the employer immunity to co-employees, as set forth in Badami and its pre-2005 progeny, is no longer applicable.
Robinson finds further support for his argument in the second paragraph of Section 287.120, which states that the exclusivity provision only limits the rights and remedies of the employee as specified in the Act. This language implicitly allows an injured employee to pursue civil remedies for claims against parties not covered by the Act. That interpretation is consistent with Section 287.150.1, which expressly preserves the employee’s right of recovery against a “third person” whose negligence caused the. workplace injury. Robinson posits that a co-employee qualifies as a third party who can be sued for tort liability.
See Schumacher v. Leslie,
We agree that the exclusivity provisions of Section 287.120 must be strictly construed in light of the 2005 amendment to the Act.
See McCracken,
With regard to Section 287.120, the determination of whether the exclusivity provision applies to co-employees depends upon the meaning of the term “employer.” When a term is defined within a statute, we must give effect to the legislature’s definition.
Jones v. Dir. of Revenue,
(1) Every person, partnership, association, corporation, limited liability partnership or company, trustee, receiver, the legal representatives of a deceased employer, and every other person, including any person or corporation operating a railroad and any public service corporation, using the service of another for pay;
[[Image here]]
(3) Any of the above-defined employers must have five or more employees to be deemed an employer for the purposes of this chapter....
§ 287.030.1 (emphasis added). The meaning of a key term in the Act is subject to strict construction.
Hager v. Syberg’s Westport,
Generally, a co-employee would not fall within this statutory definition of an “employer” as a “person ... using the service of another for pay” and “hav[ing] five or more employees.” Strict application of the definition requires us to further conclude that co-employees are not entitled to invoke the employer immunity under Section 287.120. Even though the language of the exclusivity provision was not amended in 2005, the scope of employer immunity was narrowed by the new lens of strict construction.
See Mo. Alliance
*425
for Retired Americans v. Dep’t of Labor & Indus. Relations,
Hooker cannot qualify as an “employer” based on the mere statement in the petition that she is a co-employee of Robinson. Accordingly, she is not entitled to immunity under Section 287.120, and the circuit court erred in dismissing Robinson’s petition on that ground. Unless there is an alternative ground for the dismissal (as discussed herein in the remaining points), we must reverse the judgment and remand the cause for further proceedings.
B. Doctrine of Res Judicata
Hooker’s Motion to Dismiss asserted Robinson’s tort action was barred by the doctrine of res judicata based on the settlement of his workers’ compensation claim against the City. Robinson contends the circuit court erred in dismissing his petition on this ground because there was a lack of identity between the claims and parties in the two proceedings.
The defense of
res judicata
bars any claim that was previously litigated between the same parties or those in privity with them.
Spath v. Norris,
In the workers’ compensation proceeding, Robinson sought permanent partial disability benefits from the City to cover his loss of income and medical expenses from his work-related injury. Here, Robinson has sued Hooker for her personal negligence in operating a water hose. He seeks compensation for pain and suffering, loss of consortium, and other tort-related damages that are not available under the Workers’ Compensation Act. Different facts will be necessary to prove the damage claims in the lawsuit as compared to those in the disability proceeding. The parties in the two actions are also necessarily different. Robinson could only obtain workers’ compensation benefits from his employer; he could not have brought suit against Hooker personally in the earlier proceeding. Thus, Robinson’s claim against Hooker was not merged into or barred by the earlier judgment awarding workers’ compensation benefits. There is a clear lack of identity between the two proceedings.
Hooker’s motion cited two cases to support her request for dismissal on grounds of
res judicata: Conley v. Treasurer of
*426
Missouri,
Robinson’s petition was not barred by the settlement of his benefits claim. He could not have sued Robinson for personal liability in the workers’ compensation proceeding. The circuit court erred in dismissing his lawsuit on grounds of res judi-cata. We must, therefore, reverse the judgment unless the dismissal was appropriate on the remaining alternative ground of official immunity.
C. Official Immunity
In his final point on appeal, Robinson contends the circuit court erred in dismissing his petition based on Hooker’s defense of official immunity. He argues the immunity is inapplicable because Hooker is not a public official and she was not performing discretionary acts.
“Official immunity protects public officials from liability for alleged acts of ordinary negligence committed during the course of their official duties for performance of discretionary acts.”
Davis v. Lambert-St. Louis Int’l Airport,
As a threshold requirement for official immunity, Hooker must demonstrate that she is a public official.
Lynn v. T.I.M.E.-D.C, Inc.,
Beyond her official status, Hooker must also establish that she was performing a discretionary act and not a ministerial act. The difference depends on the “degree of reason and judgment” required to perform the act.
Kanagawa v. State By and Through Freeman,
The underlying petition alleged that Robinson suffered an eye injury when his “co-employee,” Hooker, negligently operated a high pressure hose. No further factual details were provided in the pleadings or in the Motion to Dismiss. We find nothing in the record to indicate whether Hooker was a supervisor or whether she was performing a discretionary act at the time the injury occurred. Accordingly, Hooker failed to establish that she was entitled to official immunity.
The circuit court erred in dismissing Robinson’s petition on the basis of official immunity. The judgment of dismissal is reversed, and the cause is remanded for further proceedings. On remand, Hooker will have the opportunity to file a responsive pleading, and the circuit court can thereupon consider whether she has a viable affirmative defense of official immunity-
Conclusion
The judgment of dismissal is reversed and remanded consistent with the instructions set forth herein.
