Due to the extensive changes made to the Workers' Compensation Act by the General Assembly in 2005, the Commission is of the opinion that it is imperative that the basic premise of the Workers' Compensation Law be first considered, prior to reaching conclusions pertinent to the instant case.
Among its many features, the Workers' Compensation Act provides: (1) benefits to employees who sustain personal injury by accident arising out of and in the course of employment; and (2) negligence and fault are largely immaterial. Section 287.120.1 RSMo.
The construction of the phrase "arising out of and in the course of employment" historically has been broken in half, resulting in a two-prong test, with the "arising out of" portion construed to refer to causal origin, and the "course of employment" portion to the time, place and circumstances of the accident in relation to the employment. The substantive provisions of section 287.120 .1 were not changed or amended by the 2005 enactment of the General Assembly.
Pursuant to this statute proof of a compensable injury requires not only establishing that it occurred at a particular place, and at a particular time (the in the course of component) the injury must also be causally connected to some risk or hazard of the job (the arising out of employment component).
The second prong of the above mentioned two-prong test, whether the injury arose "in the course of" employment, is not in dispute in the instant case. The injury occurred within the period of employment at a place where the employee could reasonably be expected and while engaged in the furtherance of the employer's business.
The first prong, "arising out of", the test primarily concerned with causal connection, is the dispositive issue in this case.
Historically, at a minimum, our courts have required a showing that the employee's injury was caused or due to a risk of employment. Missouri cases have uniformly held that an accident and resultant injury "arise out of" the employment when there is a causal connection between the conditions under which the work was required to be performed and the resulting injury. The injury "arises out of" the employment so long as the injury was a rational consequence of a hazard connected with the employment.
Generally speaking, all risks causing injury to an employee can be brought within three categories: risks distinctly associated with the employment; risks personal to the employee; and "neutral risks", i.e., risks having no particular employment or personal character. Harms from the first category are universally compensable; harms from the second are universally non-compensable; and harms from the third result in controversy.
Various lines of interpretation of the phrase "arising out of" have historically risen of which three are the increased risk doctrine, the actual risk doctrine and the positional risk doctrine.
The increased risk doctrine, in summary fashion, requires that the distinctiveness of the employment risk can be contributed by the increased quantity of a risk that is qualitatively not peculiar to the employment.
As to the actual risk doctrine, whether the risk was also common to the public is of no concern, if it were a risk of the employment. The employment subjected employee to the actual risk that caused the injury.
The positional risk doctrine determines that an injury arises out of the employment if it would not have occurred but for the fact that the conditions and obligations of the employment placed employee in the position where he was injured.
Consequently, since risks distinctly associated with the employment fall readily within the increased risk doctrine, they are considered to arise out of the employment. As to risks personal to an employee, the origins of harm are personal and cannot possibly be attributable to employment.
However, neutral risks are defined as being neither distinctly employment nor distinctly personal in character. Furthermore, the cause is unknown, unexplainable or happenstance; known, but not associated with employment or the employee personally. In these types of risks, an award of benefits can only be justified by accepting the but for reasoning of the positional risk doctrine.
As previously mentioned, the legislature, in 2005, redefined the words accident and injury. Section 287.020.2 and section 287.020.3. In addition the legislature specifically abrogated certain earlier case law interpretations concerning the meaning of accident, as well as out of and in the course of employment. Section 287.020.10
RSMo. All three of the cases referred to in the statute that were abrogated have one component in common, i.e., it was difficult, or impossible, to ascertain where or if the employment subjected the employee to some risk or hazard greater than that to which an employee regularly experiences in everyday life. In other words,
