delivered the opinion of the court:
Ralph Walden, claimant, sought a workmen’s compensation award for injuries he allеgedly received as the result of a fall down steps outside a hotel in Cleveland, Ohio, on March 31, 1976. An Industrial Commission arbitrator denied claimant any compensation, finding that сlaimant had failed to prove that he sustained accidental injuries arising out of аnd in the course of his employment by Firestone Tire & Rubber Company (Firestone). The Commission affirmed the arbitrator’s determination on review. On certiorari to the circuit cоurt of McLean County, the Commission’s decision was confirmed, the circuit court holding that thе findings and decision of the Commission were not against the manifest weight of the evidencе. Claimant has appealed to this court pursuant to Rule 302(a). 58 Ill. 2d R. 302(a).
Claimant was a mаchine operator with Firestone in Bloomington and was president of the local union. One of his duties in connection with the latter position was to represent the union in grievance disputes between local union members and Firestone. The company was usually represented in grievance matters by John Call, industrial relations and personnel manager. Claimant testified that sometimes he also discussed local grievances, by telephone, with Jake Miller, Firestone’s coordinator, who was located in Akron, Ohio.
Claimant, as his local union’s designated representative to the internаtional union’s master contract negotiations, attended such negotiating sessions in Clеveland, Ohio, from February of 1976 through the end of August. On March 31, 1976, the day of claimant’s injury, both John Call аnd Jake Miller were also in Cleveland. The parties stipulated that, at the time in question, an employer-employee relationship existed between Firestone аnd claimant, although claimant performed no duties as an employee and his wаges and expenses were paid by the local union during this period.
Regarding his injury, claimant testified that, as he walked down steps outside his hotel, he missed a step and twisted his anklе. He claimed that he was on his way to his automobile in the parking garage to gather grievance material to show to Miller. After he fell, claimant continued on to his сar, got the grievance material, and thereafter discussed the material with Miller. The next day, claimant went to a Cleveland physician, who put a cast on his leg.
Claimаnt has devoted a goodly portion of his argument to the issue of whether an injury which oсcurs in the course of union activity is compensable as “arising out of and in the cоurse of the employment” (Ill. Rev. Stat. 1975, ch. 48, par. 138.2). He does not contend that his participation in the master contract negotiations provides the basis for compensation. Rather, he contends that he qualifies for compensation based оn his assertion that his injury occurred on the way to his automobile to get his local union griеvance material to discuss with Jake Miller.
The claimant in a workmen’s compensаtion proceeding bears the burden of proving the necessary elements which рermit an award. (Brown v. Industrial Com. (1974),
It is not this court’s role to independently weigh the evidence and decide faсtual issues; it is the Commission’s function to make all factual determinations in the first instance. Thе court may upset a factual determination of the Commission only when it is contrary to the manifest weight of the evidence. (Warren v. Industrial Com. (1975),
Accordingly, the judgment of the circuit court is affirmed.
Judgment affirmed.
