Denise Scheinert was tried and found guilty of driving while under the influence of alcohol. She had previously been arrested and charged with the same offense in 1983, after the effective date of the mandatory sentence provisions of 75 Pa.C.S. § 3731(e). On that occasion, however, she had been accepted into the Accelerated Rehabilitation Disposition program (ARD), where she successfully completed a period of probation. When, on September 30,1985, she appeared for sentencing for the later offense, the sentencing court treated her as a second offender and, consistent with the mandatory sentence provisions of 75 Pa.C.S. § 3731(e)(1)(h), imposed a sentence of imprisonment for not less than thirty days nor more than one year.1 On direct appeal from this judgment of sentence, Scheinert attacks the validity of the statutory provision which required the sentencing court to equate her prior participation in ARD with a first conviction. We find this argument lacking in merit and affirm the judgment of sentence.
*426The legislature, at 75 Pa.C.S. § 3731(e)(2), has provided as follows:
Acceptance of Accelerated Rehabilitative Disposition or any other form of preliminary disposition of any charge brought under this section shall be considered a first conviction for the purpose of computing whether a subsequent conviction of a violation of this section shall be considered a second, third, fourth or subsequent conviction.
Appellant contends that this provision is in conflict with ARD rules adopted by the Supreme Court and, therefore, invalid. The adoption of general rules governing practice and procedure, she argues, has been vested exclusively in the Supreme Court by Article 5, section 10(c) of the Pennsylvania Constitution.
The Supreme Court’s rationale for the ARD rules which it adopted was explained as follows:
The purpose of this program is to eliminate the need for lengthy motions, trials and other court proceedings, in cases which are relatively minor or which involve social or behavioral problems which can best be solved by programs and treatments rather than by punishment. In many cases, legal defenses may be available which would result in acquittal or delay in disposition of the charges. When immediate treatment is needed, however, defendant and counsel may be willing to have defendant undergo such treatment without an adjudication of guilt.
PA.R.Crim.P. 185 comment. The rules which the. Court adopted,2 however, are silent with respect to the collateral consequences of a defendant’s participation in ARD. It must be conceded, as appellant calls to our attention, that this Court has held that participation in an ARD program may not be deemed a conviction for purposes of impeaching a witness. Commonwealth v. Krall, 290 Pa.Super. 1, 434 A.2d 99 (1981). On the other hand, in Commonwealth v. Knepp, 307 Pa.Super. 535, 453 A.2d 1016 (1982), the Court held that although ARD participation did riot constitute a *427conviction, a sentencing court did not commit error by taking into consideration the defendant’s prior participation in such a diversionary program. Compare: Commonwealth v. McSorley, 335 Pa.Super. 522, 527, 485 A.2d 15,18 (1984) (Cavanaugh, J., with McEwen, J. dissenting and Cirillo, J. concurring in result), aff'd, 509 Pa. 621, 506 A.2d 895 (1986) (“caselaw does not give a clear picture of how ARD affects the status of a criminal defendant”).
These decisions, however, are not controlling of the issue now before us. The law is well-settled that “[i]t is the province of the legislature to determine the punishment imposable for criminal conduct.” Commonwealth v. Wright, 508 Pa. 25, 40, 494 A.2d 354, 361 (1985), affirmed sub nom., Pennsylvania v. McMillan, — U.S. —, 106 S.Ct. 2411, 91 L.Ed.2d 67 (1986). “The legislature has the right to fix the maximum penalty and likewise can, if it sees fit, name the minimum.” Commonwealth v. Glover, 397 Pa. 543, 545, 156 A.2d 114, 116 (1959).
The legislature, at 75 Pa.C.S. § 3731(e)(2), has provided that for the purpose of computing the number of prior convictions for purposes of determining the sentence to be imposed for driving while under the influence of alcohol, participation in ARD shall be considered a first conviction. This was clearly within the province of the legislature to do. When it did so, it did not come into conflict with ARD rules adopted by the Supreme Court. It did not legislate in an area of procedure which had been vested exclusively by Constitution in the Supreme Court of Pennsylvania. It acted solely within its province to determine the punishment for criminal conduct.
Appellant contends additionally that by equating ARD participation with a prior conviction for sentencing purposes, Section 3731(e)(2) violated her right to due process of law under the United States and Pennsylvania Constitutions.3 Fundamental fairness, she argues, commands that a prior charge may not be deemed a conviction for sentencing purposes unless the prior charge has result*428ed in an adjudication of guilt and the imposition of a judgment of sentence. We must reject this argument. Pa.R.Crim.P. 179 permits a defendant to be placed in the ARD program only after he or she has requested acceptance into the program, has indicated an understanding of the proceedings, and has accepted and agreed to comply with the conditions imposed by the trial court. “Defendants who accept ARD for drunk driving are now told that an ARD will be considered a conviction for sentencing purposes in the event of an arrest for drunk driving within the next seven years. Therefore, defendants who have accepted ARD since the effective date of the new drunk driving law have been given notice of the possible consequences of their acceptance.” Commonwealth v. Frost, 342 Pa.Super. 173, 178, 492 A.2d 448, 450 (1985). In light of the voluntary character of ARD participation and the required notice of its collateral consequences, it cannot be said that notions of fundamental fairness are violated because the legislature has directed that a person who has once been on ARD shall be sentenced as a second offender if he or she is convicted of driving while under the influence of alcohol as a result of a second arrest within a seven (7) year period. See: Commonwealth v. Godsey, 342 Pa.Super. 24, 492 A.2d 44 (1985); In re Appeal of Elias, 70 Pa.Cmwlth.Ct. 404, 453 A.2d 372 (1982); Commonwealth Department of Transportation v. McDevitt, 57 Pa. Cmwlth.Ct. 589, 427 A.2d 280 (1981), affd per curiam, 500 Pa. 532, 458 A.2d 939 (1983).
13] Appellant’s contention that she was denied due process by the Commonwealth’s failure to notify her of its intention to invoke Section 3731(e)(2) by an appropriate reference contained in the information is controlled by our decision in Commonwealth v. Reagan, 348 Pa.Super. 589, 502 A.2d 702 (1985) (en banc). In that case, we rejected the notion that due process required the Commonwealth to allege prior drunk driving convictions in a criminal information. See also: Commonwealth v. Kopycinski, 353 Pa.Super. 387, 510 A.2d 365 (1986); Commonwealth v. Potts, 352 *429Pa.Super. 299, 507 A.2d 1239 (1986); Commonwealth v. Hess, 348 Pa.Super. 600, 502 A.2d 707 (1985) (en banc).
Appellant contends finally that 75 Pa.C.S. § 3731(e)(2) is a bill of attainder and, therefore, is in violation of Article I, Section 9 of the Constitution of the United States. A bill of attainder is defined as a legislative enactment which determines guilt and inflicts punishment upon an identifiable person or group without a judicial trial. See: Nixon v. Administrator of General Services, 433 U.S. 425, 468, 97 S.Ct. 2777, 2803, 53 L.Ed.2d 867, 907 (1977); United States v. Brown, 381 U.S. 437, 445, 85 S.Ct. 1707, 1713, 14 L.Ed.2d 484, 490 (1965); United States v. Lovett, 328 U.S. 303, 315, 66 S.Ct. 1073, 1078, 90 L.Ed. 1252, 1259 (1946). However, appellant misperceives the effect of 75 Pa.C.S. § 3731(e)(2). The statute does not, as appellant suggests, inflict punishment upon persons who choose to participate in ARD programs when charged for the first time with driving while under the influence of alcohol. Rather, the statute prescribes the punishment to be imposed for a later conviction of driving while under the influence of alcohol after one has previously accepted the terms and conditions of ARD following an earlier arrest for driving while under the influence of alcohol. The conviction for which appellant was sentenced was imposed only after an adjudication of guilt. The sentence was not imposed for an unadjudicated charge which had resulted in her participation in an ARD diversionary program. The provisions of 75 Pa.C.S. § 3731(e)(2), therefore, do not require punishment Where there has been no prior adjudication of guilt by trial or guilty plea. The provisions of 75 Pa.C.S. § 3731(e)(2) do not constitute a bill of attainder; they are not proscribed by constitution.
The judgment of sentence is affirmed.
