The pivotal legal issue is whether Claimant sustained an injury by accident arising out of and in the course of employment. Employers are liable to furnish compensation to an employee who suffers a personal injury "by accident arising out of and in the course of his employment." §287.120.1. An "accident" is defined as: "an unexpected or unforeseen identifiable event or series of events happening suddenly and violently, with or without human fault, and producing at the time objective symptoms of an injury." § 287.020.2. Statutory authority for compensation for injuries by assault is set forth in section 287.120.1 RSMo 2000, which provides, in part: "the term 'accident' as used in this section shall include, but not be limited to, injury or death of the employee caused by the unprovoked violence or assault against the employee by any person" (emphasis added).
In order for an injury to be compensable, it must both "aris[e] out of" and be "in the course of" Claimant's employment. § 287.120.1. An injury "aris[es] out" of one's employment if it results from a natural and reasonable incident connected with the employment and is "the rational consequence of some hazard connected with the employment." McCutchen v. Peoplease Corp., 195 S.W.3d 421, 426 (Mo.App. S.D.,2006). An injury is said to be "in the course of" one's employment "when it occurs within the period of employment, at a place where the employee may reasonably be and while he is reasonably fulfilling the duties of his employment." Id. In certain circumstances, assaults to an employee may be compensable, and in those claims the issue raised is usually whether the assaults arose out of the employment.
In Missouri, an employee who is injured in an on-the-job assault may be entitled to compensation if the assault is related to a risk directly attributable to the employment (the dangerous nature of the duties, the dangerous work environment or the outgrowth of frictions generated by the work itself), or the assault results from irrational and unexplained incidents of a neutral origin that occur in the course of employment. Loepke v. Opies Transport, Inc., 945
S.W.2d 655, 661 (Mo.App. W.D.,1997) ${ }^{2}$. Injuries resulting from assaults committed in the course of private quarrels are not compensable under § 287.120. Id. Where, as here, the injury occurs in an assault that is the outgrowth of frictions generated by the work itself, the assault is deemed to arise out of and in the course of employment.
However, an employee injured during an assault at work may forfeit workers compensation benefits if he was the "aggressor." The aggressor defense arose from a series of cases finding an aggressor is not in the course of his employment and is not entitled to compensation for an injury caused by his own uncontrolled emotions, threats and demonstrations of assault upon another. Staten v. Long-Turner Const. Co., 185 S.W.2d 375, 381 (Mo.App.1945); McDonald v. Grahn Mfg. Co., Inc. 700 S.W.2d 157, 159 (Mo.App. W.D. 1985)(The employee's aggression operates as a complete bar to compensation regardless of the facts and circumstances which occasioned the assault). In 1969, the legislature amended the definition of "accident" by adding the following language to $\S 287.120 .1$ : "The term 'accident' as used in this section shall include, but not be limited to, injury or death of the employee caused by the unprovoked violence or assault against the employee by any person." Flowers v. City of Campbell, 384 S.W.3d 305 (Mo.App. S.D.,2012). ${ }^{3}$ Thus, the aggressor defense is rooted in the proposition the aggressor takes himself out of the course of employment, as well as in the inclusion of "injury ...[caused by] unprovoked violence or assault" in the statutory definition of accident.
Assault cases often focus on whether the claimant was the victim of "unprovoked" violence. "Unprovoked means that the claimant is not the aggressor." Loepke v. Opies Transport, Inc., 945 S.W.2d 655, 660 (Mo.App. W.D.1997). A claimant is not entitled to compensation if the claimant was the aggressor and sustained injuries as a result of his or her own threats and demonstrations of assault on another. Id; see also Wolfe v. DuBourg House/Archdiocese of St. Louis, 93 S.W.3d 855, 858 -859 (Mo.App. E.D.,2003). Whether the claimant was the aggressor is an issue of fact. See Sublett v. City of Columbia, 652 S.W.2d 189, 192 (Mo. Ct. App. 1983)(The issue is one of credibility, and the cases say that the issue is one for the [finder of fact] to solve).
The body of cases in Missouri offers some guidance as to which facts are significant in determining whether a party is an aggressor. In Van Black v. Trio Masonry, Inc,, 986 S.W.2d 200, 202 (Mo. Ct. App. 1999), it was determined offensive language does not equate with aggression, citing Stephens v. Spuck Iron \& Foundry Co., 358 Mo. 372, 214 S.W.2d 534, 539 (1948). See also, McCutchen v. Peoplease Corp., 195 S.W.3d 421, 425 (Mo. Ct. App. 2006)(an employee reacting violently to a verbal assault can be considered as the initial aggressor). The

[^0]: ${ }^{2}$ This is one of several cases cited herein that were among those overruled, on an unrelated issue, by Hampton v. Big Boy Steel Erection, 121 S.W.3d 220, 224-32 (Mo. banc 2003). Such cases do not otherwise conflict with Hampton and are cited for legal principles unaffected thereby; thus I will not further note Hampton's effect thereon.
${ }^{3}$ Although it was the intent of the legislature in adding the "unprovoked violence or assault" language to make compensable the so-called assaults of 'neutral' origin, see Person v. Scullin Steel Co., 523 S.W.2d 801, 806 (Mo. 1975), the issue of whether the claimant "provoked" the assault is raised in assaults that are the outgrowth of friction generated on the job. Dillard v. City of St. Louis, 685 S.W.2d 918, 923 (Mo.App. E.D. 1984)
claimant does not need to actually strike his assailant first to be considered the initial aggressor. Id; see also Staten v. Long-Turner Const. Co., 185 S.W.2d 375, 379-381 (Mo.App. W.D.1945). In McMutchen at 425, the court found significant the aggressor's act of throwing a bolt at the claimant, which "escalated the situation from a verbal disagreement into a physical altercation." Which party was visibly injured by the encounter has been found persuasive. McDonald v. Grahn Mfg. Co., Inc., 700 S.W.2d 157, 160 (Mo. Ct. App. 1985). While these cases highlight important factors, they also emphasize that the outcome of any aggressor case will be driven by the specific facts of the case.
In the instant case, both Claimant and Taylor were engaged in verbal assault using offensive language, but the situation escalated from a verbal disagreement into a physical altercation when Claimant, "in a flash," climbed over the passenger seat, lunged out of the truck, and struck Taylor, bloodying his lip and traumatizing his tooth. Claimant thereafter landed on the hard ground, which was the source of his alleged injury. Although Claimant testified to a factual scenario where he was the victim of an assault, I do not find that testimony credible (see findings above). I find Claimant to be the aggressor, and not the victim of an unprovoked attack.
In addition to Claimant's lack of credibility on the key issue of how he was injured, there are several other facts to support the finding Claimant was the aggressor. Taylor's bloody mouth was the only visible injury between the two, and the only explanation given for that injury was that Claimant struck him. Taylor immediately reported the assault, while Claimant did not file his report until after he spoke with his union representative. Taylor was the supervisor, and had the right to give the instructions about which Claimant complained. I find the credible evidence establishes Claimant's own uncontrolled emotions, threats and demonstrations of assault upon another are the source of his injury. He was not the victim of an unprovoked assault, and therefore did not sustain an accident in the course of his employment.
In his post-trial brief, Claimant devoted much of his argument to the proposition that the 2005 legislative changes to Chapter 287 have changed the previous judicial construct of the "aggressor defense." In Flowers v. City of Campbell, 384 S.W.3d 305 (Mo.App. S.D.,2012), the court addressed whether the 2005 legislative changes altered the prior judicial interpretation of the "assault doctrine." ${ }^{4}$ The court "conclude[d] that the legislature intended no changes in the assault doctrine, as it had been announced ... in judicial decisions preceding the 2005 amendments to Chapter 287." The Court held:
Although other changes were made to $\S 287.120, the legislature reenacted the language in \S 287.120 .1 stating that " [t]$ he term 'accident' as used in this section shall include, but not be limited to, injury or death of the employee caused by the unprovoked violence or assault against the employee by any person." 2005 Mo. Laws 913-14. When a familiar rule has received a settled judicial construction from our Supreme Court and the legislature reenacts the same statutory language without change, we presume the legislature knew about and adopted this construction of the statute.
Thus, prior rulings involving the "assault doctrine" and the "aggressor defense," both rooted in §287.120.1's definition of "accident," are still binding under strict construction.

[^0]: ${ }^{4}$ The Flowers decision acknowledged the three classes of assault in workers' compensation cases, those with some risk directly attributable to the employment, those arising from private quarrels, and those of "neutral origin," and reiterated that injuries resulting from private quarrels remain not compensable.
Further proof the aggressor defense is alive and well in Missouri is found in Van Black v. Trio Masonry, Inc. 986 S.W.2d 200, 203 (Mo.App. W.D.,1999). In that case, the court acknowledged a majority of jurisdictions now reject the aggressor defense. McDonald v. Grahn Mfg. Co., Inc., 700 S.W.2d 157, 159 n. 1 (Mo.App. W.D.1985); 1 Arthur Larson \& Lex K. Larson, Workers' Compensation Law, § 11.15(a), § 11.15(c). Jurisdictions which retain the defense include states that do so because the defense is authorized by statute. Triad Painting Co. v. Blair, 812 P.2d 638, 643-644 (Colo.1991). Such is the case in Missouri, where § 287.120(1) was amended in 1969 to include "unprovoked assaults" within the statutory definition of "accident." That subsection authorizes workers' compensation for injuries from accidents arising out of employment, and now states that the term "accident" shall "include, but not be limited to, injury or death of the employee caused by the unprovoked violence or assault against the employee by any person." Thus, Missouri law still prevents the aggressor in an assault from recovering benefits.
Finally, there is no requirement in Missouri that the aggressor act with intent or purpose. To impose such an analysis, as suggested by Claimant, would exceed the plain and unambiguous terms of the statute, which is forbidden under strict construction. Robinson v. Hooker, 323 S.W.3d 418, 423-24 (Mo.App. W.D. 2010)
