OPINION
WILLIAM C. KOCH, JR., J., delivered the opinion of the Court, in which JANICE M. HOLDER, C.J., CORNELIA A. CLARK, GARY R. WADE, and SHARON G. LEE, JJ., joined.
This appeal involves the application of the Tennessee Governmental Tort Liability Act to an action for damages filed against a defendant that was not covered by the Act when the injury-producing events occurred. The defendant filed a motion for partial summary judgment in the Circuit Court for Shelby County seeking the benefit of the claims and defenses available to government entities under the Act. The plaintiffs responded by challenging the constitutionality of legislation extending the coverage of the Act to the defendant on the ground that the legislation had been enacted after the plaintiffs had sustained their injuries. The trial court held that the Act applied to the defendant but granted the plaintiffs permission to pursue an interlocutory appeal. We granted the plaintiffs' application for permission to appeal after the Court of Appeals declined to consider the case. We have determined that applying the substantive amendment to the Tennessee Governmental Tort Liability Act enacted after the injury-producing events occurred to the plaintiffs' damage claims violates the prohibition against retrospective laws in Article I, Section 20 of the Constitution of Tennessee.

I.[1]
In mid-2002, Joyce Bell was twenty-seven years old and pregnant. On August 19, 2002, she was administered an electrocardiogram at the Regional Medical Center ("the Med") in Memphis, Tennessee. No one at the Med ever informed Ms. Bell of the test results, even though they revealed that she had an irregular heartbeat and an electrical conduction problem indicative of a potentially life-threatening condition. *826 In addition, no one ordered follow-up tests to ascertain the precise nature of Ms. Bell's cardiac problems or of the potential effects these problems could have on her unborn child.
On December 12, 2002, Ms. Bell experienced a full cardiac arrest. She was taken by ambulance to the Med where an emergency caesarian section was performed to deliver her baby. Unfortunately, Ms. Bell died. Jonathan C. Bell, her newborn child, survived but sustained severe and irreparable damage to his brain and other organs.
When these events occurred, the Med was a private charitable institution that was not considered to be a governmental entity.[2] However, on May 21, 2003, approximately five months after Ms. Bell died at the Med, the Tennessee General Assembly amended the Tennessee Governmental Tort Liability Act[3] ("GTLA") to transform the Med into a "governmental entity" for the purpose of the Actbut only from July 1, 2003 to June 30, 2006.[4] The General Assembly expressly provided that this legislation "appl[ied] to all claims filed [against the Med] on and after July 1, 2003 through June 30, 2006" and "to all other claims which arise on and after July 1, 2003 through June 30, 2006, even if the claims are filed subsequent to June 30, 2006."[5] The Governor signed the bill on June 11, 2003,[6] and it took effect less than three weeks later on July 1, 2003.[7]
On December 10, 2003, Mary Ann Bell, Ms. Bell's mother and Jonathan Bell's grandmother, filed suit in the Circuit Court for Shelby County on behalf of her deceased daughter and her grandson ("the Bell plaintiffs"). The complaint named as defendants UT Medical Group, Inc., Dr. Robert Gates, Dr. Karl Weber, and the Med and sought damages for Ms. Bell's death and Jonathan Bell's catastrophic injuries. During the course of the litigation, Stephen Bilsky replaced Mary Ann Bell as the administrator of Ms. Bell's estate and as guardian ad litem for Jonathan Bell.
On October 13, 2007, the trial court granted Dr. Weber's motion for summary judgment. On March 18, 2008, it granted summary judgments in favor of Dr. Gates and the UT Medical Group, Inc. As a result of these orders, the Med is the only remaining defendant in the case.
On March 4, 2008, the Bell plaintiffs moved for partial summary judgment against the Med. The trial court granted their motion with regard to certain undisputed *827 issues but declined to reach questions of causation. On April 22, 2008, the trial court found based upon the undisputed facts that "[i]t was the sole responsibility of [the Med] to provide the August 11, 2002, EKG of Joyce Bell to the appropriate physicians of ... [Ms.] Bell" and also concluded that the Med "failed to provide the August 11, 2002, EKG to [Ms.] Bell's physicians." Additionally, the trial court found that the Life Care Plan submitted by the Bell plaintiffs accurately reflects future health care costs and expenses for Jonathan Bell. The Life Care Plan provides for thirty million dollars in such costs and expenses exclusive of pain and suffering and the loss of enjoyment of life. The trial court, however, declined to grant summary judgment with regard to the Bell plaintiffs' assertion that the Med's failure to provide the EKG to Ms. Bell's physicians caused Ms. Bell to suffer a cardiac arrest on December 12, 2002 and that this cardiac arrest was the cause of Jonathan Bell's severe and permanent brain damage.
On July 3, 2008, the Med moved for a partial summary judgment relying on its new status as a government entity. It requested the trial court to find that "as a matter of law the provisions of the Tennessee Governmental Tort Liability Act ... apply to [the Med] in this case and that it is entitled to all of the defenses and protections therein." The Bell plaintiffs countered that the 2003 amendment to the GTLA could not be constitutionally applied to their lawsuit. The Med defended the constitutionality of the 2003 amendment to the GTLA without the assistance of the Attorney General and Reporter who, exercising his discretion pursuant to Tenn. Code Ann. § 8-6-109(b)(10) (Supp.2009), declined to defend the constitutionality of the measure.
The trial court heard the Med's motion on August 27, 2008. In an order issued on September 12, 2008, the court held that the Med "is and was a governmental entity subject to the Governmental Tort Liability Act as codified by Tennessee Code Annotated § 29-20-102, et seq., at the time of the filing of Plaintiffs' Complaint, December 10, 2003." As a result, the court found that the Bell plaintiffs' suit was subject to the limitations on lawsuits brought against a governmental entity under the GTLA, including the cap on damages.
The Bell plaintiffs quickly sought the trial court's permission to pursue a Tenn. R.App. P. 9 interlocutory appeal from its September 12, 2008 decision. The trial court granted the motion because it had "substantial reservations" regarding its ruling. In its order, the trial court identified the following reasons for its concern: (1) the "[p]laintiffs' right of actions accrued prior to the enactment of the amendment to the Governmental Tort Liability Act;" (2) "[t]his case involves the rights of a minor and the Court is conscious of its special duty to protect the rights of minors;" (3) "[t]he [p]laintiff was not dilatory in filing this case, particularly considering that it involves a claim on behalf of a minor;" (4) "[i]t was less than thirty (30) days between enactment of the amendment and the effective date of the amendment;" (5) "[t]he Court is not aware and has not been advised of how the [p]laintiff or the public at large was ever advised or given notice of the amendment in such a way that there was reasonable opportunity to file claims prior to the effective date of the amendment;" and (6) "[t]he amendment clearly affects the substantive rights of the [p]laintiff, and in particular, the amount of damages that may be recovered by the [p]laintiff." The Court of Appeals entered an order on October 22, 2008 denying the Bell plaintiffs' application for permission to appeal. On November 20, *828 2008, the Bell plaintiffs filed a Tenn. R.App. P. 11 application in this Court. We granted the Bell plaintiffs' application on February 17, 2009.

II.
A summary judgment is warranted in virtually any civil case when the party seeking the summary judgment demonstrates that no genuine issues of material fact exist and that it is entitled to a judgment as a matter of law. See Wait v. Travelers Indem. Co. of Ill., 240 S.W.3d 220, 224 (Tenn.2007); Doe v. HCA Health Servs. of Tenn., Inc., 46 S.W.3d 191, 195-96 (Tenn.2001). Thus, when the parties do not disagree regarding the material facts, issues regarding the constitutionality of the application of a statute to the facts of a particular case may be decided by summary judgment as a question of law. See Bredesen v. Tenn. Judicial Selection Comm'n, 214 S.W.3d 419, 424 (Tenn.2007); Bailey v. County of Shelby, 188 S.W.3d 539, 542-43 (Tenn.2006). Decisions involving questions of law require de novo review without a presumption of correctness. Colonial Pipeline Co. v. Morgan, 263 S.W.3d 827, 836 (Tenn.2008); State v. Burns, 205 S.W.3d 412, 414 (Tenn.2006).

III.
Throughout this proceeding, the parties have agreed that the purpose and effect of the 2003 amendment to the GTLA was to bring the Med within the GTLA's definition of "governmental entity" and that the amendment applied to the Bell plaintiffs' lawsuit against the Med. Their dispute centers on whether the application of the 2003 amendment to the Bell plaintiffs' lawsuit violates the constitutional prohibition against retrospective laws in Article I, Section 20 of the Constitution of Tennessee.
The Med concedes that the 2003 amendment resulted in "a substantive change to the law." However, it insists that the amendment was merely "a prospective change to the law" and that applying it to the Bell plaintiffs does not violate Article I, Section 20 because the Bell plaintiffs lacked any vested rights in their claim for damages until they actually filed their lawsuit. For their part, the Bell plaintiffs assert that their rights vested when Ms. Bell died and Jonathan Bell sustained his injuries and, therefore, that the application of the GTLA's cap on damages results in an unconstitutional interference with their vested rights. We have concluded that permitting the Med to characterize itself as a governmental entity for the purpose of limiting its exposure to the Bell plaintiffs' damages claims violates Article I, Section 20.

A.
Article I, Section 20 of the Tennessee Constitution guarantees "[t]hat no retrospective law, or law impairing the obligations of contracts, shall be made." Despite two new renditions of the Tennessee Constitution in 1834[8] and 1870[9] and numerous amendments to these constitutions, this provision has remained unchanged since our constitution was originally ratified in 1796.[10] The lineage of Article I, Section 20 can be traced to Article 23 of the New Hampshire Constitution of 1784.[11]*829 Approximately one hundred and seventy-five years ago, New Hampshire's Superior Court of Judicature, the state's highest appellate court at the time, observed that the "object of the clause is to protect both parties from any interference of the legislature whatever, in any cause, by a retrospective law." Woart v. Winnick, 3 N.H. 473, 477 (1826).
Other state courts construing broad constitutional prohibitions against retrospective laws similar to Article I, Section 20 have observed that their own constitutional provision provides greater protections to parties in civil matters than those provided by the United States Constitution.[12] This case does not require us to ascertain the boundaries of the rights protected by Article I, Section 20 because it presents circumstances that have been reviewed by this Court before.
Despite the facial breadth of Article I, Section 20, this Court has long taken the view that "not every retrospective law ... is objectionable in a Constitutional sense." Collins v. E. Tenn., Va. & Ga. R.R., 56 Tenn. (9 Heisk.) 841, 847 (1874). We have held that the prohibition in Article I, Section 20 "does not mean that absolutely no retrospective law shall be made, but only that no retrospective law which impairs the obligation of contracts, or divests or impairs vested rights, shall be made." Ford Motor Co. v. Moulton, 511 S.W.2d 690, 696 (Tenn.1974) (quoting Shields v. Clifton Hill Land Co., 94 Tenn. 123, 148, 28 S.W. 668, 674 (1894)); Dark Tobacco Growers' Coop. Ass'n v. Dunn, 150 Tenn. 614, 632, 266 S.W. 308, 312 (1924).
Accordingly, the Tennessee Constitution does not prohibit the retrospective application of remedial or procedural laws, unless the application of these laws impairs a vested right or contractual obligation. Stewart v. Sewell, 215 S.W.3d 815, 826 (Tenn.2007); Doe v. Sundquist, 2 S.W.3d 919, 923-24 (Tenn.1999); see also Saylors v. Riggsbee, 544 S.W.2d 609, 610 (Tenn.1976). The constitutional guarantee against retrospective laws does, however, prohibit retrospective substantive legal changes "which take away or impair vested rights acquired under existing laws or create a new obligation, impose a new duty, or attach a new disability in respect of transactions or considerations already passed." Doe v. Sundquist, 2 S.W.3d at 923 (quoting Morris v. Gross, 572 S.W.2d 902, 907 (Tenn.1978)); cf. Kuykendall v. Wheeler, 890 S.W.2d 785, 787 (Tenn.1994) (noting that "[w]hether a statute applies retroactively depends on whether its character is `substantive' or `procedural.'").
We need not tarry long on the issue of whether the 2003 amendment to the GTLA, which temporarily transformed the Med into a governmental entity, is a substantive change in Tennessee law or simply a procedural or remedial change. The Med concedes that the amendment is a substantive legal change. This concession is appropriate given that for more than three decades Tennessee's appellate courts have consistently ruled that a change to the law that alters the amount of damages constitutes a substantive, as opposed to a *830 procedural or remedial, change. See, e.g., Nutt v. Champion Int'l Corp., 980 S.W.2d 365, 368 (Tenn.1998) (quoting Shell v. State, 893 S.W.2d 416, 419-20 (Tenn. 1995)); Anderson v. Memphis Hous. Auth., 534 S.W.2d 125, 127-28 (Tenn.Ct. App.1975). Thus, in the present case, the parties are not vying over whether the statutory change is a substantive versus a procedural or remedial legal change.

B.
The issue squarely presented by this case is one of constitutional classification. The Med classifies the 2003 amendment as a constitutionally permitted prospective change in the law because the Bell plaintiffs had not filed their lawsuit before the amendment was enacted and became effective. The Bell plaintiffs classify the 2003 amendment as a retrospective law because it impairs their right to recover damages which vested when the allegedly negligent conduct occurred. Distilled to its essence, the question is whether the Bell plaintiffs' right to seek damages, unlimited by the GTLA's cap, vested when the Med's tortious conduct and the Bell plaintiffs' injuries occurred. We conclude that the Bell plaintiffs' right of action to pursue damages without the GTLA's cap on damages vested prior to the General Assembly's approval of the 2003 amendment. Accordingly, as applied to the Bell plaintiffs' lawsuit, the amendment is an unconstitutional retrospective law.
When applying Article I, Section 20 to tort cases, this Court has long recognized that "[t]he rights of the parties [are] fixed under the law as it existed at the time of the injury complained of, and any law which undertook to change those rights would be retrospective and void." Chicago, St. Louis & New Orleans R.R. v. Pounds, 79 Tenn. 127, 131 (1883); see also Crismon v. Curtiss, 785 S.W.2d 353, 354 (Tenn.1990); Miller v. Sohns, 225 Tenn. 158, 163, 464 S.W.2d 824, 826 (1971);[13]cf. Cherry v. Williams, 36 S.W.3d 78, 83 (Tenn.Ct.App.2000) (citation omitted) (noting that "[a]s a general rule, a cause of action for an injury accrues when the injury occurs, an `injury' being understood as any wrong or damage done to another's person, rights, reputation, or property").
In Miller v. Sohns, we considered this issue in the context of a plaintiff who was injured in October 1967 as a result of the negligence of three drivers in a multi-car traffic accident. In April 1968, approximately five months after the accident, the Uniform Contribution Among Tort-Feasors Act[14] took effect. One of the effects of this Act was to reduce a plaintiff's recovery against a joint-tortfeasor-defendant when the plaintiff agrees for consideration not to sue one or more of the joint tortfeasors. Mr. Sohns eventually settled his claims against two of the three defendants in return for $5,000 and proceeded to trial against the third defendant. After a jury returned a plaintiff's verdict for $5,000, the trial court declined to grant the remaining defendant's motion to reduce the verdict by the amount that Mr. Sohns had been paid by the other two drivers. Miller v. *831 Sohns, 225 Tenn. at 160-61, 464 S.W.2d at 825. The trial court reasoned that applying the Uniform Contribution Among Tort-Feasors Act to Mr. Sohns's claim would impair a right that vested at the time of the commission of the tort against him. The Court of Appeals affirmed the trial court.
This Court decided to review the decisions of the lower courts "because of the novelty of the question." Miller v. Sohns, 225 Tenn. at 161, 464 S.W.2d at 826. In affirming the decisions below, we found that "the substantive rights of plaintiff Sohns accrued ... [a]t the time of the occurrence of the accident." Miller v. Sohns, 225 Tenn. at 162, 464 S.W.2d at 826. Among the rights that accrued was a right "to make a covenant not to sue, without the amount paid by the alleged joint tort-feasor reducing the amount he might recover in a subsequent suit." Miller v. Sohns, 225 Tenn. at 163, 464 S.W.2d at 826. We also held that this right in a tort action vested for purposes of Article I, Section 20 "at the time of the commission of the tort against" the plaintiff and that any subsequent change to reduce the plaintiff's recovery violated Article I, Section 20. Miller v. Sohns, 225 Tenn. at 162, 464 S.W.2d at 826.

C.
Tennessee's courts are not alone in adopting this understanding of the restrictions imposed by state constitutional prohibitions against retrospective laws. A recent decision of the Supreme Court of Missouri is particularly illuminating because the courts in Tennessee and Missouri have adopted the same broad definition of retrospective laws originally advanced by Justice Joseph Story in an 1814 decision.[15]Compare, e.g., F.R. v. St. Charles County Sheriff's Dep't, 301 S.W.3d 56, 62 (Mo.2010) with, e.g., Owens v. Truckstops of Am., 915 S.W.2d 420, 427 (Tenn.1996).
In Klotz v. St. Anthony's Med. Ctr., 311 S.W.3d 752 (Mo.2010), the Supreme Court of Missouri confronted a case with circumstances squarely on point with the case before us. In 2004, James Klotz endured sepsis, amputation, and organ failure when his pacemaker caused an infection. In 2005, the Missouri General Assembly decreased the amount of non-economic damages that could be awarded in medical malpractice suits from $579,000 to $350,000. As with the 2003 amendment to the GTLA, the 2005 Missouri amendment expressly applied to all suits filed after a particular date irrespective of whether the tortious conduct giving rise to the suit occurred prior to or after the specified *832 date. Mr. Klotz filed suit in 2006, after the effective date of the 2005 amendment. When the case was tried in 2008, the trial court reduced the jury's award in accordance with the 2005 reduction in the cap on non-economic damages. The Supreme Court of Missouri held that the application of the lower damage cap to any claims that accrued prior to the effective date of the 2005 legislation was an unconstitutional retrospective law, even with regard to lawsuits that were not filed until after the 2005 amendment took effect. Klotz v. St. Anthony's Med. Ctr., 311 S.W.3d at 759-60.[16]
In reaching its conclusion, the Supreme Court of Missouri drew upon a prior case which had presented the inverse questionwhether a statute eliminating a damage cap could be applied to a suit seeking damages for conduct committed prior to the statutory amendment. In that case, the court had observed that
[i]t is best to keep in mind that the underlying repugnance to the retrospective application of laws is that an act or transaction, to which certain legal effects were ascribed at the time they transpired, should not, without cogent reasons, thereafter be subject to a different set of effects which alter the rights and liabilities of the parties thereto.
State ex rel. St. Louis-San Francisco Ry. v. Buder, 515 S.W.2d 409, 411 (Mo.1974). The court ultimately concluded that the damage cap "operated to protect defendants from verdicts in excess of a certain maximum" and that "[t]he decision to eliminate this protection cannot justly be applied to acts which occurred when the protection was afforded." State ex rel. St. Louis-San Francisco Ry. v. Buder, 515 S.W.2d at 411.
Our own prior decisions, as well as those of the Supreme Court of Missouri, are consistent with the historic purpose of imposing a constitutional restraint on retrospective laws in civil cases. That purpose is "to protect both parties from any interference of the legislature ... by a retrospective law." Woart v. Winnick, 3 N.H. at 477. These decisions also reflect Justice Story's insight that it would be "utterly subversive of all the objects of a constitutional prohibition on retrospective laws to allow the enforcement of provisions "which, though operating only from their passage, affect vested rights and past transactions." Soc'y for the Propagation of the Gospel v. Wheeler, 22 F.Cas. at 767.

D.
The Med's reliance on Mills v. Wong, 155 S.W.3d 916 (Tenn.2005) to support a contrary conclusion is misplaced. The Med notes that we stated in Mills v. Wong that "the Tennessee General Assembly has the sovereign power prospectively to limit and even to abrogate common law rights of action in tort as long as the legislation bears a rational relationship to some legitimate governmental purpose." Mills v. Wong, 155 S.W.3d at 922. However, we also expressly cautioned that "[t]he disturbance of vested rights through retroactive legislation implicates a different constitutional question which is not at *833 issue in this case." Mills v. Wong, 155 S.W.3d at 922 n. 5 (citation omitted). Mills v. Wong did not address the issue of retrospective versus prospective application but instead involved considerations of whether constitutional due process protections require tolling of a statute of repose for medical malpractice actions where the plaintiff was mentally incompetent during the repose period. See generally Mills v. Wong, 155 S.W.3d at 918-25.
The Med argues that Mills v. Wong ultimately supports its argument that "if vested rights can be prospectively extinguished by the General Assembly, as the Mills Court held, legislation which limits vested rights of action must also be upheld." This argument, however, ignores the constitutionally significant distinction between prospective and retrospective applications. In our application of Article I, Section 20 to tort actions, we have repeatedly found that the rights of the plaintiff vest or accrue with the commission of the tort and the resulting injury to the plaintiff. See, e.g., Crismon v. Curtiss, 785 S.W.2d at 354; Miller v. Sohns, 225 Tenn. at 163, 464 S.W.2d at 826; Chicago, St. Louis & New Orleans R.R. v. Pounds, 79 Tenn. at 131. Previous decisions of this Court also firmly establish that the General Assembly may not take away or impair a vested right through a substantive retrospective change in the law. See, e.g., Doe v. Sundquist, 2 S.W.3d at 923; Morris v. Gross, 572 S.W.2d at 907. Accordingly, we find the Med's argument unavailing.

IV.
For the reasons addressed above, the 2003 amendment to the GTLA rendering the Med a government entity for the purposes of suits filed after July 1, 2003 is unconstitutional as applied to the Bell plaintiffs whose claims for damages vested prior to the effective date of the 2003 amendment.[17] Accordingly, we reverse the trial court's September 12, 2008 order and remand the case for further proceedings consistent with this opinion. We also tax costs of this appeal to the Shelby County Health Care Corporation for which execution, if necessary, may issue.

OPINION ON THE PETITION FOR REHEARING
The Shelby County Healthcare Corporation ("The Med") has filed a Tenn. R.App. P. 39 petition for rehearing requesting this Court to reconsider our opinion in Estate of Bell v. Shelby County Health Care Corp., 318 S.W.3d 823, 2010 WL 2539644 (Tenn.2010). In that opinion, we found that the application of the Act of May 21, 2003, ch. 321, 2003 Tenn. Pub. Acts 650 ("2003 Act") to the claims of the estate of Joyce Bell and her infant son, Jonathan Bell, violated Article I, Section 20 of the Tennessee Constitution. We have determined that the arguments advanced by The Med in its petition do not merit a reconsideration of our earlier opinion.

I.
The Med's petition advances two arguments that were not previously raised either before the trial court or this Court. First, The Med asserts that it has always been a governmental entity covered by the Governmental Tort Liability Act ("GTLA") and that the 2003 Act "simply made it clear" that The Med was a governmental entity. Second, The Med insists that the doctrine of sovereign immunity, embodied *834 in Article I, Section 17 of the Tennessee Constitution, undermines the validity of our decision that the retroactive application of the 2003 Act to the claims of the estate of Joyce Bell and Jonathan Bell violates the prohibition against retrospective laws in Article I, Section 20 of the Tennessee Constitution.
We have carefully reviewed the record and the parties' briefs and have confirmed that The Med did not present either of these arguments to the trial court or to this Court in the initial briefing of this case. Appellate courts customarily decline to consider issues presented for the first time in a petition for rehearing that were not previously presented in the original hearing of the case. Harrison v. Schrader, 569 S.W.2d 822, 828 (Tenn.1978); Alexander v. Patrick, 656 S.W.2d 376, 377 (Tenn.Ct.App.1983); see also 2 Lawrence A. Pivnick, Tennessee Circuit Court Practice § 30:11, at 790 (2010). Accordingly, these issues should have been raised far earlier than in a petition for rehearing. Nonetheless, we will address them now because this opinion involves the manner in which the General Assembly may exercise its legislative power under Article II, Section 3 of the Tennessee Constitution.

II.
The Med's argument that it has always been a governmental entity is not supported by the record and is inconsistent with the position it took in the trial court. In its trial court filings, The Med stated that "[o]n July 1, 2003, The Regional Medical Center at Memphis became protected under the auspices of the Governmental Tort Liability Act" and that "[o]n July 1, 2003, the Shelby County Health Care Corporation d/b/a the Regional Medical Center at Memphis (MED), gained protection under the Governmental Tort Liability Act (GTLA)." Later, in argument to the trial court, counsel for The Med stated that "had they [the Bell plaintiffs] filed it [their complaint] on December 13th, 2002, I don't think that The Med would have come under the GTLA. I think on July 1, 2003, it did come under the GTLA."
The Med made similar arguments to this Court both in its brief and in oral argument. In its brief, The Med stated that "[p]laintiff filed the claim on December 10, 2003, more than five months after The Med was entitled to protection under the GTLA." Later in its brief, The Med "adopt[ed] and incorporate[d] by reference" an opinion issued by the Attorney General and Reporter stating that "[b]ased on these facts, one may conclude that there is a rational basis for extending the term `governmental entity' ... to include The Med." At oral argument before this Court, counsel for The Med similarly conceded that the 2003 Act was a substantive change in existing law.[1]
The Med's current argument that it has always been a governmental entity for the purpose of the GTLA is not subject to the doctrine of judicial estoppel.[2] However, a petition for rehearing is not an appropriate vehicle for advancing a contradictory position when earlier arguments have proved to be unsuccessful. Accordingly, we have concluded that this argument does not provide a basis for granting a petition for rehearing.


*835 III.
The Med next argues that the General Assembly's constitutional prerogative to prescribe the manner and limits of governmental entities' liability for civil damages should not be circumscribed by Article I, Section 20's prohibition against retrospective laws. In essence, The Med urges us to interpret the Constitution of Tennessee to empower the General Assembly to abridge an injured individual's vested right to recover damages from a governmental entity after the injury has occurred. We respectfully decline The Med's invitation to drastically restrict the application of Article I, Section 20 with regard to statutes authorizing suits against governmental entities.

The Constitution of Tennessee is the product of the sovereign will of Tennessee's citizens. State ex rel. Gouge v. Burrow, 119 Tenn. 376, 381, 104 S.W. 526, 527 (1907); Williams v. Carr, 218 Tenn. 564, 571-72, 404 S.W.2d 522, 526 (1966); Cummings v. Beeler, 189 Tenn. 151, 175-76, 223 S.W.2d 913, 923 (1949); The Judges' Cases, 102 Tenn. 509, 520, 53 S.W. 134, 136 (1899). It embodies fundamental values and articulates Tennesseans' common aspirations for constitutional governance and the rule of law. Martin v. Beer Bd. for Dickson, 908 S.W.2d 941, 946-47 (Tenn.Ct.App.1995). No branch of government is above the Constitution. This Court, as the final arbiter of what constitutional provisions mean,[3] must construe each provision in a way that gives the fullest possible effect to the intent of the Tennesseans who adopted it. Cleveland Surgery Ctr., L.P. v. Bradley Cnty. Mem'l Hosp., 30 S.W.3d 278, 281 (Tenn.2000); Prescott v. Duncan, 126 Tenn. 106, 128, 148 S.W. 229, 234 (1912).
The text of a constitutional provision is the primary guide to the provision's purpose. Cleveland Surgery Ctr., L.P. v. Bradley Cnty. Mem'l Hosp., 30 S.W.3d at 282; Hatcher v. Bell, 521 S.W.2d 799, 803 (Tenn.1974). We must interpret constitutional provisions in a principled way that attributes plain and ordinary meaning to their words, Barrett v. Tenn. Occupational Safety and Health Review Comm'n, 284 S.W.3d 784, 787 (Tenn.2009); Gaskin v. Collins, 661 S.W.2d 865, 867 (Tenn.1983), and that takes into account the history, structure, and underlying values of the entire document. Cleveland Surgery Ctr., L.P. v. Bradley County Mem'l Hosp., 30 S.W.3d at 282.
All constitutional provisions are entitled to equal respect. Thus, when called upon to construe a particular provision, the Court must consider the entire instrument, Barrett v. Tenn. Occupational Safety and Health Review Comm'n, 284 S.W.3d at 787; State v. Martin, 940 S.W.2d 567, 570 (Tenn.1997), and must harmonize its various provisions in order to give effect to them all. State ex rel. Higgins v. Dunn, 496 S.W.2d 480, 487 (Tenn.1973); Shelby Cnty. v. Hale, 200 Tenn. 503, 511, 292 S.W.2d 745, 748-49 (1956). No constitutional provision should be construed to impair or destroy another provision. Vollmer v. City of Memphis, 792 S.W.2d 446, 448 (Tenn.1990); Patterson v. Washington County, 136 Tenn. 60, 66, 188 S.W. 613, 614 (1916).

B.
Both the common-law doctrine of sovereign immunity embodied in Article I, *836 Section 17 and the prohibition against retrospective laws[4] in Article I, Section 20 have a long lineage. Retrospective statutes have been viewed with disfavor throughout this Nation's history. Eastern Enters. v. Apfel, 524 U.S. 498, 532-33, 118 S.Ct. 2131, 141 L.Ed.2d 451 (1988).[5] Retrospective statutes present problems of unfairness because they can deprive individuals of legitimate expectations and upset settled transactions. Gen. Motors Corp. v. Romein, 503 U.S. 181, 191, 112 S.Ct. 1105, 117 L.Ed.2d 328 (1992). Courts have traditionally opposed retrospective statutes because they tend to create instability and because the legislature can unfairly benefit favored groups or harm disfavored groups more easily with retrospective statutes than it can with prospective statutes. 2 Robert D. Rotunda & John E. Nowak, Treatise on Constitutional Law § 15.9(a), at 846 (4th ed.2007).
The same concern about retrospective laws that animated the debates of the framers of the United States Constitution[6] caused the framers of Tennessee's first constitution to include a specific prohibition against retrospective laws in its Declaration of Rights.[7] This prohibition was carried forward unchanged in the Constitution of 1834 and in the Constitution of 1870. Thus, Tennessee is currently one of eight states whose constitutions contain an explicit prohibition against retrospective laws. 2 Norman J. Singer & J.D. Shambie Singer, Statutes and Statutory Construction § 41:3, at 397 & n. 9 (7th ed.2009).
In Article II, Section 3, the Constitution of Tennessee expressly assigns all legislative power to the General Assembly. This power is limited only by the federal and state constitutions. Perry v. Lawrence Cnty. Election Comm'n, 219 Tenn. 548, 551, 411 S.W.2d 538, 539 (1967); Williams v. Carr, 218 Tenn. at 578, 404 S.W.2d at 529. We have noted in the past that the prohibition against retrospective laws in Article I, Section 20 is a limitation on the General Assembly's exercise of its legislative power, Dupuis v. Hand, 814 S.W.2d 340, 343 (Tenn.1991); Hanover v. Ruch, 809 S.W.2d 893, 896 (Tenn.1991); Bank of the State v. Cooper, 10 Tenn. (2 Yer.) 599, 603 (1831) (Green, J.), and that this Court has the power to determine whether the application of a particular statute violates Article I, Section 20. Wynne's Lessee v. Wynne, 32 Tenn. (2 Swan) 405, 411 (1852).
We decline to interpret Article I, Section 17 in a way that undermines the *837 traditional interpretation and application of Article I, Section 20. It is unnecessary to do so because these two provisions are easily harmonized. The General Assembly undoubtedly has control over the "manner... and courts" in which suits against governmental entities may be pursued. However, the General Assembly may not exercise this power in a way that retroactively divests citizens of vested substantive rights. Thus, the ends of these two provisions can be served by holding that the General Assembly's exercise of its power under Article I, Section 17 may not run afoul of the prohibition against retrospective laws in Article I, Section 20.[8] Accordingly, we hold that the General Assembly may exercise its authority under Article I, Section 17 to shape the contours of litigation and claims against governmental entities, but it may not retrospectively divest an individual of his or her vested substantive rights in doing so.

IV.
The Med also asserts that we should recede from our earlier opinion because of the potential ramifications that the lawsuits brought on behalf of Ms. Bell's estate and Jonathan Bell might have on its ability to provide vital medical services to residents of West Tennessee, as well as residents of Arkansas, Mississippi, and Missouri. In essence, The Med would have us base our interpretation of Article I, Section 20 on the idea that "the good of the many outweighs the good of the few." We decline to engage in this sort of delicate philosophical balancing where the Tennessee Constitution and prior precedent provide a clear resolution of this case.
The appellate record in this case contains no evidence regarding the mission of The Med. Likewise, there is a dearth of evidence regarding the services The Med provides, the demographics of the patients The Med serves or the alternatives for providing health care to these patients, the sources of The Med's funding, The Med's financial condition, or the arrangements that The Med has made for the compensation of patients injured by acts for which The Med is responsible. Without evidence of this sort, this Court, or any other court for that matter, can only speculate about the possible effect that the lawsuits filed on behalf of Ms. Bell's estate and Jonathan Bell might have on The Med's ability to carry out its mission.
The Med suggests that when the Tennessee General Assembly passed the 2003 Act, it decided that the already accrued claims of persons injured by acts attributable to The Med must be limited in order to preserve the financial well-being of The Med. We have reviewed the text of the 2003 Act and its legislative history to determine whether, in fact, the General Assembly made this choice. Neither the 2003 Act itself nor its legislative history reflect that the General Assembly enacted the 2003 Act for the purpose of altering or affecting legal claims against The Med that had already accrued.
Our examination of the text of the 2003 Act, its legislative history, and the language and legislative history of related acts has failed to identify any legislative findings regarding the existence of an existing need to assure The Med's financial stability that was so immediate and compelling that it required placing new limitations on already accrued claims. To the contrary, the legislative record reflects that many legislators understood that extending the GTLA to The Med largely *838 addressed slip-and-fall cases and traffic accidents involving The Med's employees. Many legislators appeared to believe that the 2003 Act's effect on the ability of patients to recover for negligent medical treatment would be relatively minimal because the liability for these acts would be shifted from The Med to health care practitioners who could still be sued and who were excluded from the full protections of the GTLA.[9] Stated simply, neither the record of this case nor the record of the consideration and passage of the 2003 Act provides a basis for concluding that the General Assembly enacted the 2003 Act in order to address a financial emergency by purposely abridging the rights of persons whose claims against The Med had already accrued.
This case involves a claim for damages filed on behalf of a deceased 27-year-old woman and her 7-year-old son who was born with severe and irreparable brain injuries. The complaint alleges that the woman's death and the child's injuries were caused by negligence for which The Med is responsible. While The Med's liability for the woman's death and the child's injuries has not yet been established, the parties and the trial court apparently agree that the cost to provide humane care to Jonathan Bell for the remainder of his life will be considerable. There is no evidence in this record that either Jonathan Bell or any members of his family have the financial resources to provide this care.
It is the business of the courts "to see that the scales of justice be held with an even hand." Officer v. Young, 13 Tenn. (5 Yer.) 320, 321 (1833). In its petition for rehearing, The Med asks us to use these scales to balance concrete injuries and, as yet, unrefuted allegations regarding its liability against the speculative impact that a judgment for the injured parties might have on The Med's ability to carry out its mission. Based on the state of this record, engaging in this sort of balancing would be tantamount to placing our thumb on the scales. Adopting The Med's argument would require reversing long-standing precedents of this Court and would substantially undermine the Tennessee Constitution's express protection against the imposition of retrospective laws. Accordingly, we decline to recede from our earlier conclusion, consistent with Miller v. Sohns, 225 Tenn. 158, 162-63, 464 S.W.2d 824, 826 (1971),[10] that the 2003 Act cannot be retrospectively applied to undermine the vested substantive right of Ms. Bell's estate and Jonathan Bell to pursue their claim against *839 The Med without the GTLA's cap on damages.

V.
We have considered all the arguments presented by The Med in support of its petition for rehearing,[11] and we have concluded that they fail to provide a basis for reconsideration of our earlier opinion. Accordingly, we respectfully deny The Med's petition for rehearing and tax the costs of this petition to the Shelby County Health Care Corporation for which execution, if necessary, may issue.
NOTES
[1]  The facts set forth in this opinion are drawn from the current record on appeal. Because the parties have yet to have a full hearing with regard to these facts, our inclusion of any particular fact in this opinion should not be construed as a conclusive finding of fact that prevents the parties from presenting additional evidence regarding the fact or as preventing the trial court from making contradictory findings of fact based on the evidence actually presented by the parties.

[13]  We have observed that "[a] vested right of action is property in the same sense in which tangible things are property, and is equally protected against arbitrary interference.

Rountree, 83 Tenn. 725, 731 (1885) (quoting Thomas McIntyre Cooley, A Treatise on the Constitutional Limitations Which Rest Upon the Legislative Power of the States of the American Union 449 (4th ed., Boston, Little, Brown and Co. 1868)).

[15]  In addressing a constitutional protection under the New Hampshire Constitution, which states that "[r]etrospective laws are highly injurious, oppressive, and unjust. No such laws, therefore, should be made, either for the decision of civil causes, or the punishment of offenses," N.H. Const. art. 23, Justice Story, sitting as a Circuit Justice, offered an enduring definition of what constitutes a retrospective law. Justice Story wrote:

What is a retrospective law, within the true intent and meaning of this article? Is it confined to statutes, which are enacted to take effect from a time anterior to their passage? or does it embrace all statutes, which, though operating only from their passage, affect vested rights and past transactions? It would be a construction utterly subversive of all the objects of the provision, to adhere to the former definition. It would enable the legislature to accomplish that indirectly, which it could not do directly. Upon principle, every statute, which takes away or impairs vested rights acquired under existing laws, or creates a new obligation, imposes a new duty, or attaches a new disability, in respect to transactions or considerations already past, must be deemed retrospective....

[16]  The Maryland Court of Special Appeals and the Ohio Court of Appeals have reached the same conclusion applying constitutional provisions expressly proscribing retrospective laws.

The South Carolina Supreme Court and the Wisconsin Supreme Court have reached the same result based on more generalized constitutional protections. Simmons v. Greenville Hosp. Sys., 355 S.C. 581, 586 S.E.2d 569, 571-72 (2003); Martin by Scoptur v. Richards, 192 Wis.2d 156, 531 N.W.2d 70, 86-93 (1995).

[4]  For the purpose of Article I, Section 20, a retrospective statute is one which operates forward but looks backward in that it attaches new consequences or legal significance in the future to past acts or facts that existed before the statute came into effect. See Soc'y for the Propagation of the Gospel v. Wheeler, 22 F. Cas. 756, 767 (C.C.N.H.1814) (No. 13,156); Black's Law Dictionary 1343 (8th ed.2004); William P. Wade, A Treatise on the Operation and Construction of Retroactive Laws as Affected by Constitutional Limitations and Judicial Interpretations § 1, at 2 (1880). Included within this broad definition are statutes that apply to antecedent acts or events even though the application of the statute is limited to legal proceedings filed after the date of the statute's enactment.

[8]  Other courts have reached similar conclusions. See, e.g., Greyhound Food Mgmt., Inc. v. City of Dayton, 852 F.2d 866, 869-70 (6th Cir.1988); Kaisner v. Kolb, 543 So.2d 732, 738-39 (Fla.1989); Rupp v. Bryant, 417 So.2d 658, 665-66 (Fla.1982).
[9]  Tenn.Code Ann. § 29-20-310(b)(c) (Supp. 2009). The legislators, in apparent reliance on information supplied by The Med, also appeared to assume that health care practitioners would carry their own malpractice insurance either with The Med's assistance or independently.
[10]  After our decision in Miller v. Sohns, we devised a multi-factorial framework for determining whether a right was vested for the purpose of Article I, Section 20. We stated that the four most important inquires were: (1) whether the statute advances or retards the public interest, (2) whether applying the statute retroactively gives effect to or defeats the bona fide intentions and reasonable expectations of the affected persons, (3) whether the statute surprises persons who have long relied on a contrary state of the law, and (4) whether the statute appears to be procedural or remedial. Doe v. Sundquist, 2 S.W.3d 919, 924 (Tenn. 1999). The Court in Miller v. Sohns concluded that the statute at issue could not be applied retroactively because it was substantive, rather than procedural or remedial and because it was contrary to a "well-settled" common-law rule. These findings would support a similar result using the Doe v. Sundquist analysis. By the same token, the right at issue in this casethe right to pursue a claim against The Med free from the GTLA's cap on damageswas both substantive and vested under the Doe v. Sundquist analysis.
[11]  We need not tarry long with The Med's argument that it is entitled to a rehearing because our initial opinion cited two decisions from other jurisdictions that were issued after the briefing and argument in this case was completed. Our decision rests on the prior decisions of this Court, not on these two decisions. These cases were cited as support for our observation that other state courts had adopted an approach to retrospective statutes that was similar to ours.
