OPINION
INTRODUCTION
We granted the appeal in this case to decide whether the sentences imposed by the trial court pursuant to a plea bargain agreement that exceeded provisions of the Criminal Sentencing Reform Act of 1989 are illegal. We have examined the record and considered the arguments of the parties as well as applicable law. We conclude that the sentences imposed were outside the trial court’s jurisdiction and were therefore illegal. Accordingly, we vacate appellant’s sentences and remand this case to the trial court for proceedings consistent with this opinion.
BACKGROUND
Appellant, Michael O’Neаl McConnell, was indicted on one count of first degree murder and six counts of robbery by use of a deadly weapon for offenses occurring in January 1989. On November 20, 1990, after the State filed notice that it was seeking the death penalty, appellant entered pleas of guilty pursuant to a plea bargain agreement. The agrеement provided that appellant would plead guilty as a Range I offender to the following: (1) second degree murder, for which he would be sentenced to thirty-five years; (2) five counts of robbery by use of a deadly weapon, for which he would receive five ten-year sentences to be served concurrently with the second dеgree murder sentence; and (3) one count of robbery by use of a deadly weapon, for which he would be sentenced to thirty-five years to be served consecutively to the second degree murder sentence. The trial court sentenced appellant according to the agreement for an effective sentеnce of seventy years. The sentencing calculations were based on the Criminal Sentencing Reform Act of 1982 (“1982 Act”) and not the Criminal Sentencing Reform Act of 1989 (“1989 Act”). 1
*797 On November 2, 1993, appellant filed a petition for post-conviction relief alleging that the trial court had no jurisdiction to enter thirty-five year sentences for secоnd degree murder or robbery by use of a deadly weapon. The trial court denied appellant’s petition. The Court of Criminal Appeals affirmed the lower court’s judgment and concluded that the same effective sentence could have been imposed under either the 1982 Act or the 1989 Act. We granted appellant’s application for permission to appeal to determine whether his sentences are illegal.
DISCUSSION
In this post-conviction proceeding, appellant has the burden of proving the allegations in his petition by a preponderance of the evidence.
See King v. State,
Appellant’s sole argument on appeal is that the trial court was without jurisdiction under the 1989 Act to enter thirty-five year sentences for a Range I offender on convictions of second degree murder and robbery by use of a deadly weapon. Wе agree. The 1989 Act provides that “any person sentenced on or after November 1, 1989, for an offense committed between July 1, 1982 and November 1, 1989, shall be sentenced under the provisions of [the Act].” Tenn.Code Ann. § 40 — 35—11T(b) (1997) (emphasis added). The offenses with which appellant is charged occurred in January 1989 and were followed by sentencing in 1990. Thus, the 1989 Aсt applied in this case. Pursuant to the 1989 Act, a Range I sentence for second degree murder, a Class A felony, cannot be less than 15 nor more than 25 years. See id. §§ 40-35-118, -35-111(b)(1), -35-112(a)(l). Also pursuant to the 1989 Act, a Range I sentence for robbery by use of a deadly weapon, a Class B felony, must be between 8 and 12 years. See id. §§ 40-35-118, -35-lll(b)(2), -35-112(a)(2).
The sentences that the trial court actually imposed, however, deviated from the provisions of the 1989 Act. On five counts of robbery by use of a deadly weapon, the court’s sentence of 10 years per count complied with the 1989 Act. Thus, the sentences on these counts are not in dispute. On the charge of second degree murder and the remaining charge of robbery by use of a deadly weapon, the length of the sentences imposed by the trial court exceeded that which is provided for by the 1989 Act.
The State contends that the triggering provision of the 1989 Act is not jurisdictional, thus permitting the trial court to depart from the mandates of the 1989 Act.
But see Archer v. State,
The 1989 Act did not provide for coupling different incarceration and release eligibility ranges, but we had previously approved of such a practice under the 1982 Act.
See State v. Mahler,
Our decision in
Mahler
is illustrative of the distinction between the use of plea bargaining tools and sentencing. Pursuant to a plea bargain agreement, the accused in
Mahler
pleaded guilty to murder in the second degree as a Range II aggravated offender even though his prior criminal record did not justify a Range II classification.
See
Our decision today in no way alters the ability of the State and defendants to use offender classification and release eligibility as subjects of plea bargain negotiations. These elements of plea bargaining have been and still are properly characterized as non-jurisdietional. However, we do maintain the distinction between the subjects of plea bargaining and the length of a sеntence.
Sentencing is jurisdictional and must be executed in compliance with the 1989 Act. Our Constitution grants the Legislature the power to define the limits of a trial court’s jurisdiction. Tenn. Const. art. VI, § 8 (“The jurisdiction of the Circuit, Chancery and other Inferior Courts, shall be as now established by law, until changed by the Legislature.”). Consequently, a trial court’s jurisdiction with regard tо sentencing is limited by Legislative enactments.
Compare Henderson v. State ex rel. Lance,
Previous decisions have recognized this principle when examining sentences entered pursuant to a plea bargain agreement but in excess of the relevant range classification. In
State v. Cutright,
No. 02C01-9108-CC-00175,
The State, despite the constitutional mandate concerning jurisdiction, previous court decisions, and the text of the 1989 Act, nevertheless contends that the sentence is valid. According to the State, the sentence is legal because it is what the appellant bargained for and because a similar result could be reached by applying the 1989 Act. These argumеnts, however, ignore that to affirm the sentence imposed below is to render ineffective the sentencing provisions of the 1989 Act.
While it is true that a plea bargain agreement is contractual, see
State v. Howington,
Also unsatisfactory is the State’s argument that the seventy-year sentence is appropriate because it could have been achieved under the 1989 Act through a combination of concurrent and consecutive *800 sentencing. 8 We аgree that if the trial court had applied the 1989 Act, it may well have still imposed an effective sentence of 70 years. But it is equally true that the appellant could have received a shorter sentence under the 1989 Act than the one imposed. If the trial court had imposed the same combination of concurrent and consecutive sentences using the sentencing guidelines of the 1989 Act rather than the 1982 Act, the appellant would have received a maximum effective sentence of thirty-seven years — not seventy years. The State’s argument then only emphasizes the danger of departing from the sentencing guidelines.
The sentencing guidelines of the 1989 Act are jurisdictional and binding on trial courts. The thirty-five-year sentences for second degree murder and robbery by use of a deadly weapon are for terms in excess of the provisions of the 1989 Act. Consequently, the sentence entered by the trial court is illegal and must be set aside. 9 On remand, the trial court may impose a sentence that is mutually agreeable to the State and appellant, so long as the sentence is available under the 1989 Act. If an agreement is not reached, though, appellant may withdraw his guilty plea and proceed to trial on the original charges.
CONCLUSION
We conclude that thirty-five-year sentences for a Range I offender for seсond degree murder and robbery by use of a deadly weapon are not permitted by the 1989 Act. Thus, they are illegal and must be vacated. Accordingly, we reverse the judgments of the trial court and the Court of Criminal Appeals and remand this case to the trial court for further proceedings.
Notes
. Under the 1982 Act, the maximum Range I term of imprisonment fоr both robbery by use of a deadly weapon and second degree murder was 35 years. See Tenn.Code Ann. §§ 39-2-212, 39-2-501 (1982); Tenn.Code Ann. § 40-35-109 (Supp.1983). By contrast, under the 1989 Act, the maximum Range I sentence for robbery by use of a deadly weapon *797 is twelve years. See Tenn.Code Ann. §§ 40-35-118, — 111(b)(2), -112(a)(2) (1997). The maximum Range I sentence for second degree murder is twenty-five years. See id. §§ 40-35-118, -111(b)(1), -112(a)(1).
. The Post-Conviction Procedurе Act provides that an appellant has "the burden of proving the allegations of fact by clear and convincing evidence.” Tenn.Code Ann. § 40-31-210 (1997). This Act, however, governs petitions for post-conviction relief filed after May 10, 1995, and motions filed after that date to reopen petitions for post-conviction relief that werе concluded prior to May 10, 1995. See id. § 40-30-201 Compiler’s Notes. Appellant filed petitions for post-conviction relief on November 2, 1993 and November 5, 1993, and it is from the trial court’s denial of these petitions that appellant sought permission to appeal. Thus, the former "preponderance of the evidence” standard is apрlicable in this case.
. In
Henderson,
the defendant agreed to plead guilty to a charge of armed robbery committed while he was on parole. Pursuant to the plea agreement, the defendant accepted a concurrent sentence which was entered by the trial court. A statute, however, required the trial court to impose consecutive sentencing for crimes committed by a defendant on parole. We concluded that the trial court had no jurisdiction to act in contravention of the sentencing statute, thus warranting the issuance of a writ of habeas corpus to release the defendant from his guilty plea.
See Henderson,
. In approving the use of offеnder classification and release eligibility as plea bargaining tools in
Hicks,
we distinguished
Outright
on the grounds that the
Outright
sentence "was void on its face because it reflected that the defendant ... was improperly sentenced under the 1982 Act.”
Hicks,
. Reliance by the intermediate court on our decision in
Outright
is not misplaced even though
Outright
is not a published opinion of this Court. We have previously noted that "[u]npublished intermediate court opinions have persuasive force.”
See Allstate Ins. Co. v. Watts,
. It appears that a court has permitted a plea bargain sentence that was in excess of the penalty imposed by statute in only one reported case.
See State v. Terry,
. In fact, the 1989 Act contemplates that its provisions will govern plea bargain agreements. The 1989 Act permits a court to impose a plea bargain sentence without a specific sentencing hearing or presentence report. See Tenn.Code Ann. § 40-35-203(b), -205(d) (1997). If the Legislature also wanted to permit the State and defendants to contract out of the 1989 Act altogether, it could have done so. It did not. Consequently, plea bargain sentences remain subject to the sentencing provisions of the 1989 Act.
. The 1989 Act was clearly applicable when appellаnt pleaded guilty pursuant to the plea bargain agreement in November 1990. See Tenn.Code Ann. § 40-35-117(b) (1997). It is unclear then why the State did not structure the plea agreement to comply with the sentencing guidelines of the 1989 Act when this argument impliedly concedes that it could have done so. In fact, our review of the transcript of the post-convictiоn petition hearing suggests that the State had explicit knowledge of the requirements of the 1989 Act. Counsel for appellant testified at that hearing that part of the plea bargain negotiations with the State included a specific discussion "about what would occur under the old law and specifically what would occur under the new law.” This makes the failure to comply with the 1989 Act even less understandable.
. We note that our decision is consistent with decisions of other jurisdictions that have considered the issue before this Court.
