The issue presented in this appeal is whether a work-related injury caused by a mental stimulus is compensable under the Nebraska Workers’ Compensation Act, Neb. Rev. Stat. §§ 48-101 to 48-1,117 (Reissue 1998 & Cum. Supp. 2002). Based upon long-established precedent, we conclude that it is not.
BACKGROUND
Trooper Mark Zach of the Nebraska State Patrol died on September 27, 2002, as the result of a self-inflicted gunshot wound. His surviving spouse and children, whom we shall refer to as “claimants,” brought this action for death benefits under the Nebraska Workers’ Compensation Act. Claimants alleged that while on patrol in Madison County, Nebraska, approximately 2 weeks prior to his death, Zach stopped several persons and discovered that one of them was armed with a pistol. Zach communicated the serial number of the weapon to a dispatcher, but due to a miscommunication or error, the weapon was not at that time identified as stolen. Claimants alleged that the weapon and two of the individuals stopped by Zach were subsequently involved in a bank robbery in Norfolk, Nebraska, which resulted in multiple fatalities. Claimants alleged that on the day following the robbery, Zach was advised by State Patrol officials that two of the persons he had stopped were involved in the bank robbery; that weapons taken during a previous burglary were used in the robbery; and that due to a miscommunication at the time of the stop, there had been a failure to identify the pistol used in the robbery as one of *3 the weapons involved in the previous burglary. Claimants alleged that upon learning this, Zach felt responsible and became very distraught. In support of their claim for workers’ compensation benefits, claimants alleged:
6. [Claimants’] decedent suffered an “accident” resulting in a “personal injury” inasmuch as the sudden stimulus (i.e., being advised of the consequences of an error) caused Zach’s brain to undergo physical changes which, in turn, led Zach to a state of mind which overroad [sic] his will to the extent that even knowledge of the consequences of the act of suicide did not prevent Zach from taking his own life.
7. That [claimants’] decedent suffered an “occupational disease” inasmuch as the exposure to the stress of his employment resulted in an identifiable mental disease which disease, in turn, led Zach to a state of mind which overrode his will to the extent that even knowledge of the consequences of the act of suicide did not prevent Zach from taking his own life; that the stress put upon Zach which led to his mental disease is due to causes and conditions which are characteristic of and peculiar to law enforcement inasmuch as law enforcement officers are repeatedly charged with the community’s safety, repeatedly exposed to stressful situations and suffer a peculiar'and extreme degree of stress when faced with the fatal consequences of their law enforcement activities.
The trial judge of the workers’ compensation court granted the Nebraska State Patrol’s motion to dismiss, concluding that claimants had failed to state a claim upon which relief could be granted. The judge interpreted our decisions as requiring some physical stimulus before work-related mental stress can be a compensable injury, as the result of either an accident or an occupational disease. The judge concluded as a matter of law that “the mere talking or being informed of a problem does not rise to the level of violence to the physical structure of the body” as required by § 48-151(4) and our decision in
Bekelski v. Neal Co.,
In a two-to-one opinion, the Nebraska Court of Appeals affirmed.
Zach v. Nebraska State Patrol,
We granted the petition for further review filed by the Nebraska State Patrol.
ASSIGNMENTS OF ERROR
The Nebraska State Patrol assigns, restated, that the Court of Appeals (1) erred as a matter of law by expanding the coverage of the Nebraska Workers’ Compensation Act beyond that intended by the Legislature when it presumed that being advised of the consequences of an error at work constituted an “accident” and (2) erred in interpreting Tarvin, supra, or if the interpretation was correct, that Tarvin is inconsistent with previous holdings of this court.
STANDARD OF REVIEW
An appellate court reviews de novo a lower court’s dismissal of a complaint for failure to state a claim.
Johnston
v.
Nebraska Dept. of Corr. Servs.,
The meaning of a statute is a question of law.
Bohaboj v. Rausch,
*5 ANALYSIS
Statutory Principles and Definitions
As a statutorily created court, the Workers’ Compensation Court is a tribunal of limited and special jurisdiction and has only such authority as hás been conferred on it by statute.
Foster v. BryanLGH Med. Ctr. East,
The basic principle of workers’ compensation is stated in § 48-101:
When personal injury is caused to an employee by accident or occupational disease, arising out of and in the course of his or her employment, such employee shall receive compensation therefor from his or her employer if the employee was not willfully negligent at the time of receiving such injury.
Key terms used in this principle are specifically defined by the Nebraska Workers’ Compensation Act. “Accident means an unexpected or unforeseen injury happening suddenly and violently, with or without human fault, and producing at the time objective symptoms of an injury.” § 48-151(2). “Occupational disease means only a disease which is due to causes and conditions which are characteristic of and peculiar to a particular trade . . . and excludes all ordinary diseases of life to which the general public is exposed.” § 48-151(3).
Injury and personal injuries mean only violence to the physical structure of the body and such disease or infection as naturally results therefrom. The terms include disablement resulting from occupational disease arising out of and in the course of the employment in which the employee was engaged and which was contracted in such employment.
§ 48-151(4).
The fact that suicide is alleged as the immediate cause of Zach’s death does not bar the claim because it is also alleged that Zach experienced physical changes in his brain which overrode
*6
his will to the extent that even knowledge of the consequences of the act of suicide did not prevent it. See
Friedeman v. State,
Does Operative Petition Allege Compensable Injury Resulting From Accident?
Both the review panel and the Court of Appeals concluded that the operative petition stated a workers’ compensation claim based upon accidental injury. This court first addressed the issue of compensability of an accidental injury resulting from a mental stimulus in
Bekelski
v.
Neal Co.,
It seems to us that the legislature required, not only that there should be an accident attended by objective symptoms arising out of and in the course of the employment, but that the accident must be accompanied by violence to *7 the physical structure of the body. The language indicates a clear distinction between physical and bodily injury on the one hand and mental, nervous and psychiatric injury unaccompanied by violence to the physical structure of the body on the other. The plain import of the words used eliminates from the operation of the law disabilities resulting from mental disturbances, nervousness and psychiatric ailments when violence to the physical structure of the body cannot be established.
Bekelski,
The issue of whether a compensable injury may result from a mental stimulus was next addressed in
Sorensen
v.
City of Omaha,
The critical distinction between mental and physical stimulus as the basis for a compensable injury is illustrated by
Johnston
v.
State,
Tarvin
v.
Mutual of Omaha Ins. Co.,
In this case, the allegation that Zach’s brain underwent physical changes simply identifies objective symptoms of an injury. There is no allegation that such changes were caused by any physical stimulus. To the contrary, it is specifically alleged that the changes to Zach’s brain were caused by “being advised of the consequences of an error,” which is clearly a mental stimulus. Based upon principles articulated in Bekelski and subsequent cases, an *9 injury caused by a mental stimulus does not meet the requirement in § 48-151(4) that a compensable accidental injury involve “violence to the physical structure of the body.” Accordingly, the Court of Appeals and the review panel of the Workers’ Compensation Court erred in concluding that the operative petition stated a claim for accidental injury arising out of and in the course and scope of Zach’s employment with the Nebraska State Patrol.
Does Operative Petition Allege Compensable Injury Resulting From Occupational Disease?
The trial judge concluded that the underlying condition leading to Zach’s death was “mental stress” and that “whether it be deemed from an ‘accident’ or an ‘occupational disease’ [it] must be accompanied by a prior physical insult to the physical structure of the body” under
Bekelski
v.
Neal Co.,
The issue turns on the meaning of the first two sentences of § 48-151(4). The first sentence provides: “Injury and personal injuries mean only violence to the physical structure of the body and such disease or infection as naturally results therefrom.” Id. The second sentence states: “The terms include disablement resulting from occupational disease arising out of and in the course of the employment in which the employee was engaged and which was contracted in such employment.” Id. The question is whether both sentences, or only the second, apply to injuries caused by occupational disease.
Statutory language is to be given its plain and ordinary meaning. An appellate court will not resort to interpretation to
*10
ascertain the meaning of statutory words which are plain, direct, and unambiguous.
Nebraska Liq. Distrib.
v.
Nebraska Liq. Cont. Comm.,
Although not presented with the precise issue before us in this case, we stated in
Ludwick v. TriWest Healthcare Alliance,
We conclude that under current Nebraska law, a compensable injury caused by an occupational disease must involve some *11 physical stimulus constituting violence to the physical structure of the body. Because the injury in this case is alleged to have resulted entirely from a mental stimulus, no claim is stated for injury caused by occupational disease.
Policy Considerations
The Nebraska Workers’ Compensation Act is intended to provide benefits for employees who are injured on the job, and the terms of the act are to be broadly construed to accomplish its beneficent purposes. See
Vonderschmidt v. Sur-Gro,
Nebraska is one of only five states having workers’ compensation statutes which define compensable injury in terms of violence to the physical structure of the body. See, Del. Code Ann. tit. 19, § 2301(15) (2005) (Delaware); Idaho Code Ann. § 72-102(18)(c) (2006) (Idaho); La. Rev. Stat. Ann. § 23:1021 (8)(a) (Cum. Supp. 2007) (Louisiana); Mo. Ann. Stat § 287.020.3(5) (West Cum. Supp. 2006) (Missouri). Of these states, both Idaho and Louisiana allow compensation for injuries caused by mental stimulus, but their compensation acts contain additional separate and express provisions governing this subject. See, Idaho Code Ann. § 72-451 (2006); La. Rev. Stat. Ann. § 23:1021(8)(b) through (d) (Cum. Supp. 2007) (setting forth specific requirements that must be met for mental injury to be compensable). Nebraska does not have similar provisions in its compensation act.
We are not persuaded by the holding of the Supreme Court of Delaware that a disabling work-related mental disorder is compensable under a statute requiring a showing of violence to the physical structure of the body, whether or not preceded by a physical injury. See
State
v.
Cephas, 637
A.2d 20 (Del. 1994). As this court first noted in
Bekelski
v.
Neal Co.,
CONCLUSION
For the reasons discussed, we conclude that the Court of Appeals erred in affirming the judgment of the Workers’ Compensation Court review panel which reversed the order of dismissal entered by the trial judge. We therefore reverse the judgment of the Court of Appeals and remand the cause to that court with directions to remand the matter to the review panel with directions to affirm the order of dismissal entered by the trial judge.
Reversed and remanded with directions.
