OPINION
This appeal addresses the issue of whether the Legislature may transfer a proprietary function of a municipality to a governmental function without violating the open courts or equal protection provisions of the Texas Constitution. We hold that it may and affirm the trial court’s judgment.
Background
In 1990, Phillip Salvatierra and his wife were watching their three-year-old, Robert Justin Salvatierra, ride his tricycle on the sidewalk in front of their home. What happened next is disputed: VIA Metropolitan Transit Authority (“VIA”) claims the youngster either rode into the path of the bus or was pushed into the street. In an affidavit opposing summary judgment, Phillip Salvati- *181 erra states he saw a city bus, owned and operated by VIA, attempt to make a right turn from 20th Street onto Ruiz Street, “when the driver improperly maneuvered the bus and ‘jumped’ the corner curb” and ran over the child. Robert Justin sustained a severe crush injury to his left leg, resulting in amputation above the knee, and numerous surgeries.
The Salvatierras sued VIA, its driver, and others under theories of negligence and product liability. A summary judgment, a trial, a non-suit, and a settlement have disposed of all parties except VIA. The trial court granted a partial summary judgment in favor of the plaintiff on the ground that a prior confession of judgment precluded VIA from disputing liability. With the issue of damages suffered by the minor child remaining to be determined, VIA tendered $100,000 into the registry of the Court and the trial court, on VIA’s motion, entered a summary judgment which limited damages to that amount on a theory of sovereign immunity under the Texas Tort Claims Act. See Tex. Civ. PRAC. & Rem.Code § 101.023(b). On appeal, the appellant challenges the constitutionality of the cap on damages provided in the Texas Tort Claims Act as applied to a personal injury claim against VIA, claiming that the statute violates the open courts doctrine and the equal protection provision of the Texas Constitution.
VIA: A Brief Historical Survey 1
Until the middle of the present century, San Antonio’s mass transportation was provided by private enterprise. In the late nineteenth and early twentieth centuries electric street car companies provided transportation throughout the city.
See Lakeview Land Co. v. San Antonio Traction Co.,
In 1959, the City of San Antonio purchased the city’s private bus company and renamed it the San Antonio Transit System (“SATS”). During this time, its operation of the bus company would be classified as a proprietary function as opposed to a governmental function, and in such capacity the city was liable for its torts.
Cf. Dias v. City of San Antonio,
In 1973, the Legislature enacted article 1118x to permit the state’s urban areas to develop rapid transit systems.
See
Tex rev. Civ. Stat. Ann. art. 1118x,
repealed and now codified in
Tex. Transp. Code § 451.001
et seq.
(Vernon Supp.1998);
City of Humble v. Metropolitan Transit Authority,
In accordance with this legislation, the City of San Antonio passed an ordinance creating VIA on February 3, 1977, and the citizens of San Antonio confirmed this act by election on November 8, 1977. VIA purchased the facilities and equipment of San Antonio Transit System from the City of San Antonio and commenced operations on March 1,1978.
Appellant views this series of events as having unconstitutionally transformed the *182 city’s bus company from one exercising proprietary functions and subject to unlimited tort liability to one exercising governmental functions and subject to limited liability. In five points of error, combined for purposes of argument, appellant summarizes the issue:
Is the reclassification of municipal transportation from a proprietary function to a governmental function pursuant to Tex. TraNSP. Code § 451.052 a violation of the open courts provision and the right to equal protection under the Texas Constitution, as an unreasonable and arbitrary restriction upon an injured plaintiffs ability to recover damages available to that plaintiff at common law?
Standard of Review
As the summary judgment turned on a legal issue, the standard of review in this appeal is one which applies to constitutional challenges against a state statute. We begin our review with a strong presumption that the statute is constitutional.
See Texas Nat’l Guard Armory Bd. v. McCraw,
Texas Tort Claims Act
Governmental entities enjoy sovereign immunity to the extent it has not been waived.
See
Joe R. Greenhill & Thomas V. Murto, III,
Governmental Immunity,
49 Tex. L. Rev. 462, 462 (1971). The state has the legal authority to limit the terms of consent to be sued and limit the total dollar amount to which it is willing to subject itself to liability on a claim.
See Trinity River Auth. v. Williams,
The Act’s waiver of immunity is limited in at least two ways: by the types of claims that can be brought against a governmental unit, Tex. Crv. Prac. & Rem.Code § 101.021, and by a cap on damages. Id. at § 101.023. Section 101.023 does not circumscribe a plaintiffs total recovery for a given injury. Instead, it delineates the extent of the government’s waiver of immunity from liability for that injury. See University of Texas at El Paso v. Nava,701 S.W.2d 71 , 72 (Tex.App.-El Paso 1985, no writ). When a plaintiff suffers an injury that falls within the Tort Claims Act, the Legislature has agreed to hold the government liable up to a specified dollar amount.
Edinburg Hosp. Auth. v. Trevino,
The Texas Transportation Code defines what a rapid transit authority is and is not. It is a public political entity and corporate *183 body of perpetual succession which exercises public and essential governmental functions. Its operation is not proprietary for any purpose. See Tex. Transp. Code Ann. § 451.052 (Vernon Supp.1998). Its exposure to tort liability is confined to the provisions of the Tort Claims Act. See id. at § 451.052(e); Tex. Civ. Prao. & Rem.Code ANN. § 101.023 (Vernon Supp.1998). In 1987, the Legislature amended the Tort Claims Act to reclassify some previously proprietary functions, including transportation systems, as governmental functions, thereby placing such entities under the shield of immunity’s cap on damages.
The Authority to Create VIA
Appellant argues that the cap on damages when applied to mass transit authority liability is constitutionally infirm because Article 1118x was not supported by an enabling constitutional amendment. VIA replies that the Legislature may use its general police powers to create new entities. We agree. The impetus to create mass transit authorities was “to help the state’s urban areas remedy their ever-expanding problems such as traffic congestion and air pollution which resulted in part from the lack of mass transit systems in those areas.”
City of Humble,
[T]he state constitution is not a grant of power, but a limitation upon the power of the state to act. Therefore, absent an express or directly implied prohibition in that document, it follows the legislature is free to enact laws which it deems are in the best interest of the people of the State.
Id. at 493, citing to
Shepherd v. San Jacinto Junior College Dist.,
The Open Courts Doctrine
Next, appellant argues that the damage cap of the Tort Claims Act violates the Texas Constitution guarantee that “[a]ll courts shall be open, and every person for an injury done him, in his lands, goods, person or reputation, shall have a remedy by due course of law.”
See
Tex. Const. art. I, § 13. This provision provides at least three separate constitutional guarantees: (1) courts must actually be open and operating; (2) the Legislature cannot impede access to the courts through unreasonable financial barriers; and (3) the Legislature may not abrogate well-established common law causes of action unless the reason for its action outweighs the litigants’ constitutional right to redress.
See Central Appraisal Dist. of Rockwall v. Loll,
Appellant argues that because VLA’s predecessors — the privately and publicly-owned bus companies which formerly operated in the city — were liable to suit for unlimited damages, the 1973 reclassification of mass transit operations as a governmental function, with its limited waiver of immunity under the Tort Claims Act damages cap, constitutes an open courts violation. The cap on damages represents a limitation on appellant’s claim to $100,000 regardless of the extent of the injury.
There is no question that appellant’s son could establish a cognizable common-law cause of action if suit were brought against a private bus company.
Cf. Sax v. Votteler,
We thus consider whether this statutory restriction on appellant’s recovery is unreasonable or arbitrary when balanced against the statute’s purpose. Appellant argues that the damages claimed far exceed the cap and *184 there is no express or implied purpose behind the transportation code which justifies the cap. VIA argues that this restriction is reasonable when balanced against the purpose of former article 1118x to ease the problems associated with urban growth, such as air pollution and traffic congestion.
We are obliged to look to the legislature “as the authorized spokesman of state policy in the matter of what is or is not governmental for tort immunity purposes.”
City of Corsicana v. Wren,
No doubt airports, like railroad terminals and ship wharves, could be, and in some instances are, run by private enterprise, even as, only a short time back, education was a strictly private affair and, further back, tax collection and military operations were sometimes farmed out by governments to private persons. But this does not mean that airport operation, when conducted by a city or other governmental entity, cannot be honestly classed as governmental, especially when we know that in our own state most or all important airports are municipally owned and operated.
Id.
The Equal Protection Argument
Appellant further argues that a limitation on damages presents an equal protection violation because damages which exceed the $100,000 cap are not accorded the same opportunity for redress as those claims which can be fully compensated under the cap. This challenge has been rejected previously as to the Tort Claims Act and as to former article 1118x.
See Texas Dep’t of Mental Health and Mental Retardation v. Petty,
For these reasons, we overrule appellant’s points of eiTor and affirm the judgment of the trial court.
Notes
. The following background was gleaned from appellant’s brief.
. In 1970, the $100,000 limitation on damages brought considerably more redress than it does in 1998. While we do not find that cap arbitrary and unreasonable in the context of the time it was created, we do think it is time the Legislature reviewed the reasonableness and adequacy of this cap in light of the changes in costs and valuations that have occurred since 1970. Ultimately, however, we feel that this analysis and decision is clearly within the Legislature's realm, not ours.
