OPINION
In this case the Commonwealth appeals the trial court’s determination that section 9712 of the Mandatory Minimum Sentencing Act, 42 Pa.C.S. § 9712, is unconstitutional. That section requires the imposition of a minimum sentence of five years total confinement if it is established by a preponderance of the evidence that the defendant was in visible possession of a firearm during the commission of certain felonies.1 In light of our recent decision in Commonwealth v. Wright, 508 Pa. 25, 494 A.2d 354 (1985), we find it unnecessary to discuss at length the issues raised in this appeal.
1.
On January 6, 1983, Appellee Cannon was convicted of three counts of robbery as felonies of the first degree, carrying a firearm on the public street, and possessing an instrument of crime. He was sentenced to serve two concurrent three-to-ten year terms, to be followed by five years probation.
