OPINION
In this direct appeal, we must resolve whether a trial court had the authority to impose a mandatory fine, which it initially *383 neglected to render in its judgement of sentence. At issue in this case is the interpretation by a trial court of the mandatory minimum sentencing provisions of 18 Pa.C.S. § 7508. The trial court concluded, and the Superior Court agreed, that where the Commonwealth properly invokes the mandatory sentencing provisions found in 18 Pa.C.S. § 7508, the trial court must apply the entire, relevant provision and can correct, at any time, a sentence it has imposed that fails to conform to the statute. After studying the terms of 18 Pa.C.S. § 7508 and reviewing the relevant case law, we find no error with the conclusions reached by the trial court and the Superior Court.
I. FACTS AND PROCEDURAL HISTORY
On February 4, 1992, two City of Philadelphia police officers observed Jose Vasquez (Appellant) trafficking in items they believed to be controlled substances. The' police arrested Appellant and recovered 120 packets of heroin, a Schedule I controlled substance. 1 The aggregate weight of the seized heroin was 3.2 grams. After a bench trial, the trial court convicted Appellant of possession 2 and possession with intent to deliver a controlled substance. 3 Appellant filed post-trial motions, which the trial court denied. On June 1, 1994, the trial court sentenced Appellant to a term of imprisonment of two (2) to five (5) years, pursuant to 18 Pa.C.S. § 7508(a)(2)(i). 4
Appellant filed a timely appeal to the Superior Court, challenging his competency to stand trial and his waiver of a jury trial. Neither Appellant nor the Commonwealth presented any questions to the Superior Court concerning the appliea *384 tion by the trial court of the mandatory sentencing provisions. The Superior Court affirmed the conviction but vacated the Judgment of Sentence and remanded the matter to the trial court for resentencing. The Superior Court acknowledged in its unpublished opinion that the trial court had made a direct request that it remand for resentencing. In a Rule 1925 opinion, 5 the trial court indicated that it had “inadvertently omitted” the mandatory fine of five thousand dollars ($5,000.00) 6 from the sentence and urged the Superior Court to remand the case. In a concurring and dissenting opinion, Judge Johnson disagreed with the appropriateness of the remand, finding that the Commonwealth failed to preserve for appeal or request review of the issue concerning the mandatory fine. Appellant filed a Petition for Allowance of Appeal with this Court, which we denied on December 8, 1995. On remand, following a hearing, the trial court sentenced Appellant to a period of incarceration of two to four years and ordered him to pay the mandatory fine. The Superior Court affirmed the Order of the trial court without dissent in an unpublished opinion.
II. DISCUSSION
A. MANDATORY MINIMUM SENTENCING PROVISION
Generally, the imposition of a sentence is vested in the sound discretion of the trial court.
Commonwealth v. Gribble,
*385
The legislature established mandatory minimum sentences for drug trafficking convictions by enacting 18 Pa.C.S. § 7508. Section 7508 sets forth the minimum penalties that apply to specific drug offenses. The terms of the statute are clear that sentences may not deviate from the minimum limits set forth by Section 7508.
7
Once a trial court has determined that the Commonwealth has established the requirements of a legislatively mandated sentence, the trial court has no discretion to deviate its sentence from that which is defined by statute.
Commonwealth v. Myers,
Appellant does not dispute the applicability of Section 7508(a)(2)(i) to his conviction. He raises no issue regarding the identification of the controlled substance or its weight. Furthermore, Appellant does not dispute the finding by the trial court that the Commonwealth notified both the trial court and him after conviction and before sentencing that it intended to seek the mandatory minimum sentence provided by *386 Section 7508. See 18 Pa.C.S. § 7508(b) (requiring the Commonwealth to provide reasonable notice). Instead, Appellant makes a purely procedural argument. He suggests that the notice provided by the Commonwealth must state the precise punishment it will seek, pursuant to the mandatory provision, and, here, he alleges that the Commonwealth failed to declare its intent to petition for imposition of the mandatory fine. Appellant argues that when the Commonwealth seeks only part of a mandatory provision of Section 7508, the judiciary has no power to interfere with its discretionary act.
When the words of a statute are clear and free from ambiguity, courts must not substitute an alternate meaning. 1 Pa.C.S. § 1921(b);
Hayes v. Mercy Health Corp.,
*387 B. WAIVER OF ILLEGALITY OF SENTENCES
Appellant also contends that the Superior Court lacked the authority to remand the matter for resentencing and the trial court possessed no jurisdiction to modify its sentence. Pursuant to Rule 1410 of the Pennsylvania Rules of Criminal Procedure, if the Commonwealth wishes to petition the trial court to modify its sentence, it must file its motion within ten (10) days after imposition of the sentence. Pa.R.Crim.P. 1410;
Fajohn v. Commonwealth, Dept. of Corrections,
The Commonwealth does not contest Appellant’s assertions that the Commonwealth failed to file a timely motion to modify the sentence or preserve the issue for direct appeal. Rather, the Commonwealth maintains that, because the initial sentence lacked the mandatory fine, it was illegal from its inception and always susceptible to correction. We agree.
“[C]laims concerning the illegality of the sentence are not waivable.”
Commonwealth v. Smith,
The Superior Court committed no error by vacating the sentence and remanding the case to the trial court. It is clear from the Rule 1925 opinion of the trial- court that the Commonwealth notified Appellant and the trial court of its intention to seek a sentence under 18 Pa.C.S. § 7508., By omitting the fine, in contravention of 18 Pa.C.S. § 7508(a)(2)(i), the original sentence was illegal. Because the initial sentence was illegal, the trial court possessed the authority to mold a new, statutorily correct sentence. We find no merit to Appellant’s claim that the trial court improperly imposed a new sentence that added a fine of five thousand dollars ($5,000.00) to the existing term of years.
For the foregoing reasons, we affirm the Order of the Superior Court, which affirmed the Judgment of Sentence of the Court of Common Pleas of Philadelphia County.
