Opinion by
Judge Palladino,Robert Thomas Merryman (Petitioner) appeals from an order of the Workmens Compensation Appeal Board which reversed a referees decision and granted disability benefits against Petitioner to Richard H. Adam (Claimant). For the reasons set forth belowj we vacate and remand.
Petitioner is in the coal transportation business. As part, of his operation, Petitioner leases trucks from Gerard A. Hansel (Owner) to be used for the delivery of coal. On August 22, 1978, Claimant, a truck driver, was involved in an accident while operating a truck leased by Petitioner from Owner. Claimant suffered a temporary total disability for injuries sustained in the accident. Neither Petitioner nor Owner disputes that Claimant was injured in the course of his employment or that he is entitled to benefits for his injuries. The merits of the dispute center on which party was Claimants employer for workmens compensation purposes at the time of his injuries.
*599On September 26, 1978, Claimant filed a claim petition against Owner for injuries sustained in the August 22 accident. Subsequently, on November 13, 1978, Claimant filed an amended claim petition for workmens compensation against Owner and/or Petitioner. This amended petition was captioned Adam v. Hansel and/or Merryman. Following several postponements, an evidentiary hearing was held before a referee on February 20, 1979, at which the Claimant and both Owner and Petitioner participated. Several more hearings were held and briefs from all parties were finally received by January 3, 1980.
On February 4, 1980, the referee issued a decision captioned Adam v. Hansel, whereby the referee determined Owner to be Claimants employer and awarded benefits accordingly. On the next day, February 5, 1980, the referee issued a second decision captioned Adam v. Merryman. In this decision, the referee stated that “[t]his case was combined for trial with the case of Richard Adam v. Gerard Hansel, and there were seven hearings held in this matter.”1 The referee thereafter made findings of fact and concluded that Petitioner was not Claimants employer for workmens compensation purposes.
On February 26, 1980, Claimant appealed the second referees decision alleging that “the referee erred in dismissing the claim as to Robert Thomas Merryman and in holding that the claimant had failed to show an employer-employee relationship.”2 In a lengthy opinion, the Board, which made no reference to the referee’s first captioned Adam v. Hansel, sustained Claimant’s appeal *600and ordered the referee to make further findings with respect to the details of the accident, the resultant disabilities, and his average weekly earnings so as to make an appropriate award of compensation.
Despite the Boards directive, the referee, on remand, again dismissed the claim petition on grounds that Petitioner was not Claimants employer. Claimant appealed, and the Board reversed and remanded with instructions that the referee award appropriáte compensation or the Board would order the case reassigned. The referee subsequently issued a decision in conformance with the Boards directive. Petitioner appealed this final decision to the Board, and the Board affirmed on April 1, 1985.
Petitioner subsequently filed a petition for rehearing with the Board3 alleging that the Board had erred in affirming the referees decision awarding benefits against Petitioner. Petitioner argued that the Boards order permitted a circumstance whereby the Claimant gained two awards. of compensation for the same work injury and payable by two different employers. The Board denied Petitioners petition for rehearing in an order dated January 28, 1987 stating that “the defendants petition is dismissed as moot as the Board has consolidated the prior proceedings in the case of Richard Adam v. Gerard Hansel, and the Commonwealth Court has been provided with the complete record.” The matter has now come before this court for review.
Petitioner argues that the procedural posture in which this case has been presented for our review grants to the Claimant two separate compensation claims for one injury and that this constitutes legal error. We agree.
*601The Board has made no determination with respect to the legal significance of the prior referees determination. It is not this courts function to step in and perform the role of the Board in issuing determinations awarding compensation to a particular claimant against a single or joint parties. Rather, our proper appellate function is to make certain that Board orders are free from legal error and supported by substantial evidence. In this case the Board has erred in creating a situation where there exist two separate apparently valid claims against two parties for a single claimant. Accordingly, we vacate the Boards decision and remand for proceedings consistent with this opinion.
