Opinion by

The Court of Common Pleas of Somerset County (trial court) sustained the appeal of William Yarbinitz (Appellee) from the six-month suspension of his drivers license. The Department of Transportation (DOT) has appealed. We reverse.

Appellee received a notice of suspension from DOT, dated March 20, 1981, which stated that because of Appellees conviction of November 4, 1980 under §3733 of the Vehicle Code 1 (Fleeing or Attempting to Elude Police Officer) his license would be suspended for six months, effective April 24, 1981. In his appeal to the trial court, Appellee asserted that he had surrendered his license to the District Justice before whom he entered his guilty plea, and so was entitled to credit against the suspension. The trial court found that: 1) Appellees conviction occurred on September 27, 1980, not November 4, 1980 as the suspension notice indicated; 2) Appellee had surrendered his license to the District Magistrate on the date of his conviction; and 3) Appellee was entitled to credit from September 27, 1980 to May 9, 1981, the date DOT restored his operators license pending the appeal.

Because the trial court determined that Appellee had already served the six-month suspension, it sustained Appellees appeal. In this appeal from the trial courts decision, DOT asserts that: 1) the trial court had no authority to compute credit against the suspension; *171 2) assuming credit was available against the suspension, this is not grounds for sustaining an appeal from a suspension; and 3) even if the trial court possessed the authority to calculate and grant credit, Appellees testimony alone is insufficient to establish that the license was surrendered to the District Magistrate for purposes of the six-month suspension, or that the magistrate forwarded the license to DOT.

We agree with DOTs assertion that, for purposes of a license suspension appeal, a trial court lacks the authority to compute and give credit for any time that DOT may have been in possession of an operators license. The function of the trial court in an appeal from a license suspension is to determine the validity of the suspension. Department of Transportation, Bureau of Traffic Safety v. Quinlan, 47 Pa. Commonwealth Ct. 214, 408 A.2d 173 (1979). Once the identity of the party whose license is suspended is established and the grounds for the suspension are found to be proper, the trial courts inquiry is ended. Even assuming Appellee was entitled to credit, this is not a basis for sustaining the appeal. If the person whose license is suspended committed the offense, and if the offense is a valid basis for suspension and no violation of due process has occurred, then the suspension must be upheld and the operators appeal dismissed. The trial court can do no more. Therefore, a suspension cannot be invalidated if it was properly imposed, even if it has already been served.

Because the trial court improperly sustained Appellees appeal, we reverse and reinstate the six-month suspension of Appellees drivers license. If Appellee believes he is entitled to credit against the suspension for time DOT may have been in possession of his license, his recourse is to apply to DOT. 2
